Description

Cleaning products based on oil-containing microemulsions

The present invention relates to cleaning products based on oil-containing microemulsions and the process for their preparation, which are nevertheless aesthetic and which can be used as shower gels, shampoos, cleaning preparations, hand-washing products, bath preparations, make-up removers or shaving products. The products can be low-viscosity or gel-like, can foam lightly or strongly and / or can be used as antibacterial rinse-off formulations. The cleaning products are very mild to the skin and aesthetic. The microemulsions can serve as impregnation medium for wipes, tissues that are used wet or dry by the consumer or can also be applied from a pumpoamer.

Cosmetic treatment of the skin and hair also includes cleaning them. Cleaning means removing unwanted dirt, removing all types of germs and increasing mental and physical well-being. Preparations containing surfactants are primarily suitable for cleaning.

Surfactants are amphiphilic substances that can dissolve organic, non-polar substances in water. Due to their specific molecular structure with at least one hydrophilic and one hydrophobic part of the molecule, they ensure a reduction in the surface tension of the water, wetting of the skin, facilitating dirt removal and removal, easy rinsing and, if desired, foam regulation.

The hydrophilic parts of a surfactant molecule are mostly polar functional groups, for example -COO ^" , -OSO ₃ ^2" , -SO ₃ ^" , while the hydrophobic parts generally represent non-polar hydrocarbon residues generally classified according to the type and charge of the hydrophilic part of the molecule. There are four groups:

• anionic surfactants, • cationic surfactants,

• amphoteric surfactants and

• nonionic surfactants.

Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In aqueous solution they form negatively charged organic ions in an acidic or neutral environment. Cationic surfactants are characterized almost exclusively by the presence of a quaternary ammonium group. In aqueous solution, they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and accordingly behave in aqueous solution like anionic or cationic surfactants depending on the pH. They have a positive charge in a strongly acidic environment and a negative charge in an alkaline environment. In the neutral pH range, however, they are zwitterionic, as the following example should illustrate:

RNH ₂ ⁺ CH ₂ CH ₂ COOH (at pH = 2) X ^" = any anion, eg Cl ^"

RNH ₂ ⁺ CH ₂ CH ₂ COO ^" (at pH = 7)

RNHCH ₂ CH ₂ COO- B ⁺ (at pH = 12) B ⁺ = any cation, e.g. Na ⁺

Polyether chains are typical of non-ionic surfactants. Non-ionic surfactants do not form ions in an aqueous medium.

Common manifestations of cosmetic or dermatological preparations and cleaning products are finely dispersed multiphase systems in which one or more fat or oil phases are present in addition to one or more water phases. Of these systems, the actual emulsions are the most widespread.

In simple emulsions there are finely dispersed droplets of the second phase enclosed by an emulsifier shell in the one phase (water droplets in W / O or Li pidvesicles in O / W emulsions). The droplet diameters of the usual emulsions are in the range from approx. 1 μm to approx. 50 μm. Such "macroemulsions", without further coloring additives, are milky white and opaque. Finer "macroemulsions", whose droplet diameters are in the range from approx. 4x 10 ^'1 μm to approx. 1 μm, are, again without coloring additives, bluish white and opaque ,

Micellar and molecular solutions with particle diameters smaller than approx. 10 ^"2 μm are reserved to appear clear and transparent.

The droplet diameter of transparent or translucent microemulsions, on the other hand, is in the range from about 10 ^"2 μm to about 4 x 10 ^{" 1} μm. Such microemulsions are usually of low viscosity. The viscosity of many O / W type microemulsions is comparable to that of water.

The advantage of microemulsions is that active substances can be more finely dispersed in the disperse phase than in the disperse phase of "macroemulsions". Another advantage is that they can be sprayed due to their low viscosity. A disadvantage of the microemulsions of the prior art is that a high content of one or more emulsifiers must always be used, since the small droplet size requires a high interface between the phases, which generally has to be stabilized by emulsifiers.

In itself, the use of the usual cosmetic emulsifiers is harmless. Nevertheless, emulsifiers, like any chemical substance, can cause allergic or hypersensitive reactions in individual cases.

Microemulsions based on anionic surfactants are known. EP 0529883 describes preparations which, in addition to lauryl ether sulfate and betaine, contain a cationic deposition polymer. It is disadvantageous that on the one hand only silicone oils can be used and on the other hand the proportion of the oil is only 1% by weight in contrast to 18% by weight of surfactants. The emulsification of more oil components while maintaining transparency has not been achieved. Transparent systems are obtained when water is no longer used in O / W microemulsions. However, these systems are then not to be regarded as an O / W microemulsion, but rather as pure oil bases, oil baths, as described in DE 19712678.

Another problem with the provision of microemulsions with anionic, cationic or amphoteric surfactants is that the oil components are very difficult to use, since the surfactants are often too water-soluble and therefore have hardly any emulsifying properties. Furthermore, the surfactants mostly contain salts, which have a great influence on the emulsifying power. Furthermore, surfactant mixtures often have to be adjusted to pH values between 5 and 7 with acids such as citric acid, which likewise leads to a change in the interface properties and thus often complicates the incorporation of oil components while maintaining transparency. The prior art lacks a manufacturing specification for oil-containing yet transparent microemulsions which are mild to the skin as cleaning products.

DE 3534733 describes microemulsions, but the proportion of solubilized oil components is low in the range from 0.5 to 3% by weight. The problem of incorporating larger quantities of oil is also clear in WO 9948473, here the incorporation of only 0.5-1% by weight of oil is mentioned.

WO 0047166 describes microemulsions based on MIPA laureth sulfate. Laureth-9, Myreth-9, sodium laureth-10-carboxylic acid, ethoxylated castor oil and cocamidopropylbetaine are used as cosurfactants in the examples. From the examples it can be seen that the ratio of the surfactants to the solubilized oil is very large. This disadvantage of the surfactant mixture allows a maximum of 5% by weight of oil to be solubilized. A further problem that the combination of cationic substances with anionic surfactants often leads to precipitation of the corresponding surfactant mixture due to the electrostatic attraction of both substances is not mentioned in WO 0047166.

EP 668754 describes transparent preparations which are anionic

Contain surfactants, 3-15% by weight of oil, a polar, nonionic emulsifier (HLB 5-10) and 1-5% by weight of an ethoxylated monoglyceride ether. The disadvantage is that only Lauryl ether sulfate can be used, the formulas cannot be adjusted to low viscosities like water and a special polar emulsifier (Rewoderm LIS 75) is required. DE 4411557 describes microemulsions which contain 8% by weight of oil. In addition to lauryl ether sulfate, only low ethoxylated W / O emulsifiers (ceteth-5, oleth-5) are used as surfactants. It is disadvantageous that the mixtures foam little and contain no conditioning agents. It is also known that foams that consist only of the anionic surfactant lauryl ether sulfate produce a flash foam, but this quickly becomes unstable. The stability can be achieved by cosurfactants such as betaine, glutamate, sarcosinate or amphoacetate, but this is not considered advantageous in DE 4411557. The surfactant systems typically used for rinse-off products are also not described.

DE 19755488 describes microemulsions which either contain very little water or very much water. In the latter case, however, the microemulsions are characterized by a very high polyol content of 12-30% by weight. The oil phase mentioned consists of glyceryl oleate or cetyl alcohol, so that in the cosmetic sense it is rather a matter of W / O emulsifiers and consistency enhancers. Strictly speaking, the microemulsion described consists of anionic surfactants such as lauryl ether sulfate, cocoglyceride and the W / O emulsifiers mentioned. Only cetyl laurate (hexyldecanol laurate) with a proportion of 2.2% by weight is to be regarded as a real oil component. Solubilizing larger amounts of oil is obviously difficult here, too, since a total of 33.2% by weight of surfactants and W / O emulsifiers are required in order to clearly disperse about 2% by weight of oil. Another disadvantage is the high content of hexanediol of 12% by weight and short-chain glycerol esters such as glyceryl caprylate of 12-15% by weight, since these substances are irritating to the skin in the concentrations listed.

An important point to consider when developing cleaning products is their skin tolerance. In the case of the microemulsions described above, there is no information about their skin compatibility in comparison to corresponding oil-free surfactant mixtures or oil-containing emulsion products which were prepared with anionic surfactants. The choice of surfactants and the sometimes very high concentration of the surfactants seems to be responsible for this. The object of the present invention is to provide oil-containing cleaning products which do not have the disadvantages of the known cleaning products listed. Another object of the present invention is to enrich the state of the art and to provide cleaning products and their production processes which have a relatively high oil content and are nevertheless aesthetically pleasing and above all skin-friendly.

Another object of the present invention is to provide oil-containing cleansing products which can be applied, distributed and washed off in a manner which is pleasant to the senses, the skin-care oil phase remaining on the skin.

Furthermore, it is necessary to solve the problem of cleaning products that have a relatively high oil content but do not foam.

The stated tasks are solved by a process for the production of microemulsions as cleaning preparations and the cleaning preparations thus produced according to the main claims. The subclaims relate to advantageous embodiments of the preparations according to the invention. The invention further comprises the use of such preparations.

It was surprising and unforeseeable for the person skilled in the art that oil-containing microemulsions, which can be used as cleaning products, by the combination of a) a primary surfactant, b) one or more cosurfactants, c) optionally one or more W / O emulsifiers, i.e. ) one or more liquid and / or solid oil phases, e) optionally a thickener and f) the addition of 0 to 4% by weight of salts, the primary / cosurfactant ratio being variable with a constant total amount of surfactant and transparent emulsions be preserved. The corresponding microemulsions remedy the disadvantages of the prior art. When solving the problems, the multifactorial dependency in the production of oily and possibly foaming microemulsions must be taken into account. The factors, the type of oil phase used, the amount of oil, the pH value, the salt content and the primary / cosurfactant ratio influence the transparency of the microemulsion. The factors of pH, salt content, the amount of thickener, the W / O emulsifiers and the primary / cosurfactant ratio in turn influence the viscosity of the microemulsion. Nevertheless, surprisingly, with a constant total surfactant content, a microemulsion results with a variable primary / cosurfactant ratio.

It has proven advantageous that the primary surfactant, e.g. laurethersulfate or lauryl sulfate, and the cosurfactant, e.g. betaines, amphoacetate, glutamate or sarcosinate, have the same total surfactant content of e.g. 15% by weight, can be changed so that microemulsions continue to result. Variable phmar / cosurfactant ratios of 14: 1, 13: 2, 11: 4, 9: 6 etc. can be set and a microemulsions is obtained in any case. Recipes that have such flexibility with regard to the choice of surfactant are advantageous because the foaming power as well as the compatibility of the respective formulation depend heavily on it.

These relationships have been known for oil-free surfactant mixtures, but have not yet been explored for the oil-containing compositions. Since microemulsions are extremely sensitive to such variations, since the interface properties then change greatly, the present invention has remedied an existing deficiency which is disclosed in the above-described microemulsions.

Foaming is particularly advantageous because the consumer associates cleaning performance with it. In general, oil-free formulations foam particularly well if the surfactant / cosurfactant content or the surfactant ratio are selected accordingly. An advantage of the formulations according to the invention is that they foam even in the presence of oil.

In the case of the microemulsions according to the invention, variation in the relative surfactant proportions to one another is furthermore not restricted to a specific oil component. Active ingredients of different hydrophilicity / lipophilicity can thus be more easily can be used because the oil phase can be chosen flexibly. Furthermore, when using larger concentrations of oils and lipids, they themselves adhere better to the skin or hair, so that products of this type have greater care potential. The use of larger concentrations of oil phases also enables lipophilic, hydrophilic or surface-active substances to adhere, since the remaining lipid film on the skin after showering, bathing, cleaning the face, washing hands, removing makeup or after shaving , The washability of these substances is difficult compared to microemulsions with a small oil phase or compared to oil-free surfactant mixtures.

The use of larger concentrations of oil components with a protective lipid film is advantageous since the adhesion of surfactants after a rinse-off process is often problematic. This adherence can lead to intolerance to contact dermatitis if products containing surfactants are used frequently. This disadvantage does not occur with preparations according to the invention because lipid deposition takes place on the skin.

Another advantage of the microemulsions according to the invention is to formulate low-viscosity microemulsions with the advantages described above and also microemulsion gels. For example, a low-viscosity microemulsion can be advantageous for a bath additive, while a gel-like consistency is more favorable for a shower product, since the product is then present in large quantities when it is distributed in the palm of the hand.

It is surprising and particularly advantageous that oil-containing formulations according to the invention turn out to be much milder than oil-free compositions. Although a general one

Theory for this is lacking, it is assumed that the surfactants prefer to the

Cleaning products responsible. When the microemulsion according to the invention is used, a lipid film is formed which is more protective than low-oil ones

Compositions or compared to oil-free recipes. Therefore they are

To a certain extent or not at all leads to the removal of the stratum corneum lipids, proteins or natural moisturizing factors. Surprisingly, this effect can only be observed for the oil-containing microemulsions according to the invention. For use as a cleaning product, this is associated with a further significant advantage, since a pleasant, noticeable lipid film remains on the skin after use, which naturally lacks low-lipid or lipid-free formulations. This is interesting for those consumers who, for example, do not apply lotion after showering.

Was surprisingly further that the incorporation can be effected by lipid-soluble drugs or amphiphilic lighter compared to formulations with low ^"oil phase or in comparison to oil-free Tensidabmischungen. Further, simultaneously or separately and hydrophilic agents may be used to advantage.

The adherence of the active ingredients to the skin / hair is facilitated after a rinse-off process.

Furthermore, the microemulsions according to the invention can be used very well as impregnation media for wipes and fabrics which can be used by the consumer wet or dry. The compositions with the ultra-fine droplets are easily drawn onto the fiber, which is an advantage. Furthermore, the soaked products can also lead to a foam when used with water on the skin.

The addition of a lipophilic co-emulsifier such as glycerol ester, propylene glycol ester, sorbitan ester low ethoyl. Glycerides, diglycerides or triglycerides are advantageous because they can lower the interfacial tension more. The lack of suitable co-emulsifiers in known preparations is explained by the fact that frequently only unstable formulations in the presence of the surfactants result in the presence of oil or that only simple emulsions can be obtained. This disadvantage has also been met according to the invention.

The influence of the salt content is only insufficiently appreciated in microemulsions of the prior art. This is despite the fact that the salt content is important for the successful production of cosmetic cleaning products. The surfactants often contain salts due to the manufacturing process. In the case of oil-free market formulations based on surfactants, the additional use of table salt changes the viscosity from low-viscosity to gel-like. This high salt content can make the successful production of microemulsions difficult. The microemulsions according to the invention advantageously allow the additional salt content to be added between 0 and 4% by weight, provided the surfactants are not salt-free. For microemulsions which are to be produced from salt-free surfactants, the salt content would have to be set between 0 to 4% by weight plus the salt content which is present in the salt-containing surfactants.

Furthermore, the microemulsions of the prior art do not aim at how important the pH is for the transparency of the mixtures. For example, it is advantageous to adjust the pH to 5.5 using citric acid or other acids. However, the addition of acids changes the interfacial properties of the surfactants, so that a microemulsion with pH 8 can become white or unstable by adding acid at pH 5.5. In microemulsions or microemulsion gels according to the invention, the relative ratios of surfactants / cosurfactants and W / O emulsifiers or by varying the salt content make it possible to obtain microemulsions regardless of the pH, which is not possible in the formulations of the prior art.

It was also astonishing that, in addition to lauryl ether sulfate or lauryl sulfate, a variety of milder cosurfactants can be used as exemplary primary surfactants. The surfactants can advantageously be selected from:

A. anionic surfactants acylamino acids and their salts, such as

Advantageous quaternary surfactants are alkyl betaine, alkyl amidopropyl betaine and alkyl amidopropyl hydroxysulfain. Cationic surfactants can also preferred according to the present invention are selected from the group of quaternary ammonium compounds, especially benzyltrialkylammonium chlorides or bromides de, for example benzyldimethylstearylammonium chloride, also ammonium salts Alkyltrialkylam-, for example cetyltrimethylammonium chloride or bromide, Alkyldime- thylhydroxyethylammoniumchloride or bromides, dialkyldimethylammonium or bromides, dialkyl ethoxylate dimethyl ammonium chlorides or bromides such as, for example, di (C14-C18) alkyl (EO) 3-20 dimethyl ammonium salts or distearyl (EO) 5 dimethyl ammonium chloride and distearyl (EO) 15 dimethyl ammonium chloride.

The total surfactant content, consisting of primary surfactant and cosurfactant, is in the range from 1 to 30% by weight. The total surfactant content is preferably 25% by weight and the primary / cosurfactant ratio can be set variably in the range from 14: 1 to 1:14.

The droplets of the discontinuous oil phase can be connected to one another by one or more crosslinking substances, known as thickeners Crosslinker structure is characterized by at least one hydrophilic area which has an extent which is suitable for bridging the distance between the microemulsion droplets and by at least one hydrophobic area which is able to interact in a hydrophobic manner with the microemulsion droplets.

WO 9628132 shows the backbone of a water-soluble or water-dispersible thickener, the branching points representing covalently bound hydrophobic groups to the polymer. The hydrophobic residues can attach to one another through hydrophobic interaction. Microemulsion droplets can also attach to the crosslinking sites through hydrophobic interactions. It is in principle irrelevant whether the hydrophobic residues "immerse" or whether the hydrophobic residues only come into superficial contact with the microemulsion droplets and adhere to them to a greater or lesser extent. It is equally advantageous if the crosslinking substance, within the scope of the This description also referred to as the thickener, forms an independent gel network in which the microemulsion droplets are then held in place by hydrophobic interaction (so-called associative thickeners are present), or whether the network is held together by the crosslinking with the microemulsion droplets in the nodes of the network is effected.

The crosslinking substances used according to the invention generally follow structure schemes as follows:

A I A— B— A A— B— A

I I

A— B— A A A (1) (2) (3)

where B symbolizes a hydrophilic region of the respective crosslinker molecule and A each represents hydrophobic regions, which may also be of a different chemical nature within a molecule.

and analogously formed, even more complex structures definitely fall within the scope of the invention presented here.

A— B— Z— B— A A A (9) (10) (11)

(12) (13)

where Z represents a central unit, which can be hydrophilic or hydrophobic and usually consists of an oligo- or polyfunctional molecular residue. Of course, thickeners with a higher degree of branching also fall within the scope of the present invention.

For example, in scheme (10), Z can consist of a glyceryl residue, the three OH functions of which merge into regions B, which in turn can represent, for example, polyoxyethylene chains of the same or different lengths, and whose terminal OH group is esterified with a longer-chain fatty acid. Partial substitution of glycerol is also conceivable, which can result in structures which correspond to scheme (9).

The hydrophilic groups B can advantageously be chosen such that the crosslinking agent is water-soluble or at least dispersible in water, the hydrophobic portion of the groups A then being overcompensated.

For the structure scheme (1), for example, the following more specific structure schemes can be followed:

H-fO-CH-CH ₂ -fO-fCH ₂ -CH ₂ -θ -hCH-CH2-OjH

where R 1, R ₂ , R ₃ , R, R ₅ and R _{6 can} independently represent branched or unbranched, saturated or unsaturated, cyclic or chain-like aliphatic, aromatic or heteroaromatic radicals, for example branched or unbranched or cyclic alkyl or alkanoyl radicals , Aryl or aroyl radicals substituted or unsubstituted by alkyl or aryl substituents or also alkylated or arylated organylsilyl radicals. x means numbers which allow the entire molecule to be soluble or at least dispersible in water, typically selected from the range greater than 10, advantageously from the range 20-300. a and b

Numbers chosen depending on x are such that the

Those skilled in the art are known per se and require no further explanation.

For the structure scheme (2), for example, the following more specific structure schemes can be followed:

ι where R 1, R ₂ and R _{3 can} independently represent branched or unbranched, saturated or unsaturated, cyclic or chain-like aliphatic, aromatic or heteroaromatic radicals, for example branched or unbranched or cyclic alkyl or alkanoyl radicals, substituted or unsubstituted by alkyl or aryl substituents Aryl or aroyl residues or also alkylated or arylated organylsilyl residues. x, y and z mean, independently of one another, numbers which allow the entire molecule to be soluble or at least dispersible in water, typically selected from the range greater than 10, advantageously from the range 20-300.

Partial substitution is also conceivable, where one or more of the indices x, y, or z can assume the value zero and one or more of the radicals R 1, R ₂ or R ₃ can represent hydrogen atoms.

For the structure scheme (3), for example, the following more specific structure schemes can be followed:

where R _L R ₂ , R ₃ and R _{4 can} independently represent branched or unbranched, saturated or unsaturated, cyclic or chain-shaped aliphatic, aromatic or heteroaromatic radicals, for example branched or unbranched or cyclic alkyl or alkanoyl radicals, substituted by alkyl or aryl substituents or unsubstituted aryl or aroyl residues or also alkylated or arylated organylsilyl residues. u, v, w and x mean, independently of one another, numbers which allow the entire molecule to be soluble or at least dispersible in water, typically selected from the range greater than 10, advantageously from the range 20-300.

Here too, it goes without saying that partial substitution is conceivable, where one or more of the indices u, v, w, x can assume the value zero and one or more of the radicals R 1, R ₂ , R ₃ or R ₄ can represent hydrogen atoms. The substances naturally go into other structural schemes.

For the structure scheme (9), for example, the following more specific structure schemes can be followed:

where R _{1 t} R ₂ , R ₃ and R can independently represent branched or unbranched, saturated or unsaturated, cyclic or chain-like aliphatic, aromatic or heteroaromatic radicals, for example branched or unbranched or cyclic alkyl or alkanoyl radicals, with alkyl or aryl substituents sub - substituted or unsubstituted aryl or aroyl residues or also alkylated or arylated organylsilyl residues. x and y mean, independently of one another, numbers which allow the entire molecule to be soluble or at least dispersible in water, typically selected from the range greater than 10, advantageously from the range 20-300.

For the structure scheme (10), for example, the following more specific structure schemes can be followed:

where R 1, R ₂ and R _{3 can} independently represent branched or unbranched, saturated or unsaturated, cyclic or chain-like aliphatic, aromatic or heteroaromatic radicals, for example branched or unbranched or cyclic alkyl or alkanoyl radicals, substituted by alkyl or aryl substituents or unsubstituted aryl or aroyl residues or also alkylated or arylated organylsilyl residues. x, y and z mean, independently of one another, numbers which allow the entire molecule to be soluble or at least dispersible in water, typically selected from the range greater than 10, advantageously from the range 20-300.

For the structure scheme (11), for example, the following more specific structure scheme can be followed:

where R 1, R ₂ , R ₃ and R _{4 can} independently represent branched or unbranched, saturated or unsaturated, cyclic or chain-shaped aliphatic, aromatic or heteroaromatic radicals, for example branched or unbranched or cyclic alkyl or alkanoyl radicals, substituted by alkyl or aryl substituents or unsubstituted aryl or aroyl residues or also alkylated or arylated organylsilyl residues. u, v, w and x mean, independently of one another, numbers which allow the entire molecule to be soluble or at least dispersible in water, typically selected from the range greater than 10, advantageously from the range 20-300. k, I, m and n can independently represent numbers from 0 to 50.

For the structure scheme (12), for example, the following more specific structure scheme can be followed:

where R _{1 t} R ₂ , R ₃ , R ₄ and R _{5 can} independently represent branched or unbranched, saturated or unsaturated, cyclic or chain-shaped aliphatic, aromatic or heteroaromatic radicals, for example branched or unbranched or cyclic alkyl or alkanoyl radicals, with alkyl or aryl substituents substituted or unsubstituted aryl or aroyl radicals or also alkylated or arylated organylsilyl radicals. u, v, w, x and y mean, independently of one another, numbers which allow the entire molecule to be soluble or at least dispersible in water, typically selected from the range greater than 10, advantageously from the range 20-100.

For the structure scheme (13), for example, the following more specific structure scheme can be followed:

where R ₁ , R ₂ , R ₃ , R ', R ₅ and R _{6 can} independently represent branched or unbranched, saturated or unsaturated, cyclic or chain-like aliphatic, aromatic or heteroaromatic radicals, for example branched or unbranched or cyclic alkyl or alkanoyl radicals , Aryl or aroyl radicals substituted or unsubstituted by alkyl or aryl substituents or also alkylated or arylated organylsilyl radicals. u, v, w, x, y and z mean, independently of one another, numbers which allow the entire molecule to be soluble or at least dispersible in water, typically selected from the range greater than 10, advantageously from the range 20-1000.

It may also be advantageous to modify the structural schemes described above in such a way that branching occurs again at the end of the thickener molecule, approximately as it is realized in the group of so-called dendrimers.

Particularly suitable crosslinkers have been found to be those selected from the

Group of polyethylene glycol ethers of the general formula RO - (- CH ₂ -CH ₂ -O-) _n -R ', where R and R' independently of one another are branched or unbranched alkyl, aryl or alkenyl radicals and n is a number greater than 100, the etherified fatty acid ethoxylates of the general formula R-COO - (- CH ₂ -CH ₂ -O-) _n -R ', where R and R' independently of one another are branched or unbranched alkyl, aryl or alkenyl radicals and n is a number greater than 100, the esterified fatty acid ethoxylates of general formula R-COO - (- CH ₂ -CH ₂ -O-) _n -C (O) -R \ where R and R "independently of one another are branched or unbranched alkyl, aryl or alkenyl radicals and n is a number greater than 100 represent the polypropylene glycol ether of the general formula RO - (- CH ₂ -CH (CH ₃ ) -O-) _n -R ', where R and R' independently of one another are branched or unbranched alkyl, aryl or alkenyl radicals and n is a number larger represent as 100, the esterified fatty acid propoxylates of the general formula

It is also advantageous to add mixtures of the polymers described above use, for example from PEG 800 distearate and PEG-800 Chol ₂ .

Furthermore, celluloses, for example hydroxypropylmethylcellulose (HPMC), which are not to be regarded as crosslinking agents, are also particularly advantageous. Combinations of HPMC and the crosslinkers described above can also be used.

A slightly modified way of forming microemulsion gels according to the invention is to immobilize the oil droplets by using hydrophobically modified, synthetic or natural polymers. Such polymers are sometimes referred to as associative thickeners.

It is accordingly also advantageous, in particular if the thickener or thickeners are to be selected from the group of associative thickeners, to select hydrophobically substituted polysaccharide derivatives, for example hydrophobically substituted cellulose ethers, hydrophobically substituted starches, alginates, glucans, chitins, dextrans, caseinates, pectins , Proteins and gums, also polyurethanes, polyacrylamides, polyvinyl alcohols, polyacrylates, water-soluble silicone polymers and the like.

The oil components can advantageously be present in a content of 1 to 50% by weight, based on the total preparation, about 1 to 40% by weight are preferred.

It was also astonishing that very high concentrations of oils and lipids (1-15% by weight) can be used with a total surfactant content of 15% by weight (active) and W / O emulsifier content of 0.0 to 10% by weight. Furthermore, the total surfactant content (less than 15% by weight) can also be lower without the microemulsion structure (for example transparency when water-clear preparations are sought) being lost.

The adhesion of the substances can be further improved by using waxes (ester waxes, triglyceride waxes, ethoxylated waxes, etc.) in the oil phase or as an oil phase. It is preferred if the wax component or all of the wax components are selected from the group of the esters from saturated and / or unsaturated, branched and / or unbranched alkane carboxylic acids or hydroxycarboxylic acids with a chain length of 1 to 80 C atoms and saturated and / or unsaturated, branched and / or unbranched alcohols with a chain length of 1 to 80 C atoms, from the group of esters from aromatic carboxylic acids and saturated and / or unsaturated, branched and / or unbranched alcohols with a chain length of 1 to 80 C atoms, provided that Wax components or the entirety of the wax components at room temperature represent a solid, the natural waxes, the diesters of polyols and C10-C80 fatty acids, the ethoxylated waxes, the triglyceride waxes, the C16-C60 fatty acids and / or C16-C80 fatty alcohols, the mineral oil waxes.

By using waxes (ester waxes, triglyceride waxes, ethoxylated waxes, etc.) in the oil phase or as an oil phase, the adhesion of the active ingredients and moisturizers can be further improved.

Furthermore, light protection filters can also be used much more easily, so that shower-on products result, ie the user receives directly during the Showering a protective protection against sun rays for skin and hair. The expert knows how difficult it is to formulate sun protection filters in shower products containing surfactants while maintaining transparency.
