Ethyl cellulose grams 15 Alcohol cc 80 Solution No. 2
Polyethylene glycol having an average molecular weight of 1500 grams 20 Polyethylene glycol having an average molecular weight of 1000 grams 50 Alcohol cc 70 Castor oil cc 100 Each of the solutions are made separately, and then Solution No. 1 is added slowly to Solution No.2 while both are at between 100 F. and 140 F., and stirred vigorously to an intimate and perfectly smooth mixture; then left to cool to room temperature before packaging for use.
The percentages by volume of ingredients in the foregoing resultant compound are approximately:
Per cent Ethyl cellulose 3.7
Alcohol" -4 48.0 Castor oil -i 29.0 Polyethylene glycol 19.3
evaporated and the compound has become set,
the compound being sufficiently fluid initially to make using of the coating easy and practicable.
Instead of castor oil, some other suitable oil non-toxic to the skin, may be employed, such as for example, blown soy-bean oil, di-butyl phthalate, tri-cresyl phosphate, special-processed linseed oil, or some similar compatible products, such liquids acting as a permanent plasticizer or softener for the waxes in the composition.
The, alcohol selected is fully evaporative and is preferably an anhydrous ethyl or a grain alcohol, non-toxic of course, as are all of the other ingredients of the compound.
Other waxy materials may be employed instead of thosementioned, as by way of example, stearic acid, paraffinewax, carnauba wax, beeswax, etc., although it is preferable that the waxy materials have a melting pointat aboutthat of the human body-heat, this being true of the polyethylene glycols suggested. Such waxy materials, will then hold their shape after being applied, and will be unaffected after application, by weather conditions. They will remain permanently sufiiciently moist, especially after they have been plasticized with the oil ingredient of the compound, so that at all times, removal from the hand may be effected through a simple wiping operation.
The coating compound set forth will form a film or coating on the hand, to act as abarrier to prevent the penetration of nail polish therethrough, and will remain moist as just described, so as to always be removable from the hand by a simple wiping operation, without further moistening.
In use, the compound is brushed or otherwise applied to the hands, in an area or strip about an or more, wide, as an edging about the nail or nails to be polished, and if any portion of the nail itself is to be only partially polished, such predetermined area is similarly coated. The alcohol in the solution will evaporate after the compound has been applied, to thus thicken or set the rest of the compound on the fingers, such a setting taking perhaps a minute or two.
After having set, the coating forms a film that is permanently moist and waxy, and nail polish is insoluble therein, or at least very difficultly solublein the time during which manicuring is accomplished, so that even though some of the polish does inadvertently get past the boundary of predetermined areas of color and onto the previously initially coated areas of the skin, these last-mentioned areas will have been so protected by the coating that the, lacquer will not penetrate therethrough.
Now, after the color has dried on the nails,
a simple wiping operation, as with a dry piece of absorbent sheet or, material, is all that is-necessary, in which action no color. is removed from the initially unprotected areas, but will come off the other portions where it has adhered to the undercoating of protective or non-penetrant material.
If so desired, the composition may be such that instead of being permanently moist so as to be removable by wiping,-it may set or harden so as to be removable by lifting or peeling, and in this event, it is not necessary to wait until the lacquer has dried on the nails before removing the protective coating. Such peeling of the coating will not disturb the lacquer intended to be left on the nail, and any excess of undesired coloring on the protective coating will simply comev olT therewith.
In manicuring according to the manner set forth, such pre-treatment of the nails leaves a neat and attractive colored area on the nails so processed, and one wherein the edges of the nails are rather accurately and sharply defined and delineated to meet the intended desires of the operator. 1
It is now clear that the flowable product described above, prepared in rough proportions as indicated in the description of the manner of preparation of Solution No. 1 and Solution No. 2, consists essentially of a waxy material, a cellulose derivative, a volatile solvent, and a compatible softener, the waxy material and compatible softener together constituting the major quantity of the non-volatile ingredients. position given hereinabove is illustrative of the essential ingredients of the composition and also illustrates approximately. the quantitive relations between the ingredients but it is understood that they may be varied considerably and still obtain a product which will have the property offorming a substantially non-drying film which is impenetrable to nail polish and which will remain moist to be removed by a simple wiping operation. What we claim as new and desire to secure by Letters Patent is:
1. A composition for applying to the fingers prior to applying nail polish .to bound and define a nail polish receiving area, the composition com together The specific comprising the following ingredients in approximately the following proportions:
Percent Ethyl cellulose 3.7 Alcohol 48.0 Castor oil 29.0 Wax 19.3
2. A flowable composition for applying to the fingers prior to applying nail polish to bound the nail and define a nail polish receiving area thereof; the composition consisting essentially of a waxy material, a cellulose derivative and a volatile solvent therefor, and a compatible softener plasticizing the waxy material; the waxy material and compatible softener together constituting the major quantity of non-volatile ingredients, and the composition having the property of forming a substantially non-drying film impenetrable to nail polish.
3. The composition set forth in claim 2 in which the plasticizer content is approximately 29%.
4. The composition set forth in claim 2 in which the content of waxy material is approximately one-fifth.
5. The composition set forth in claim 2 in which the content of plasticizer is about threetenths and the waxy material content is about one-fifth.
6. The composition set forth in claim 2 in which the waxy material has a melting point of approximately body temperature.
