Description

Reinigungsmittelcleaning supplies
Die vorliegende Erfindung betrifft ein neues Reinigungsmittel, insbesondere zur Verwendung in industriellen Bereichen.The present invention relates to a new cleaning agent, in particular for use in industrial areas.
Reiniger sind zumeist tensidhaltige Formulierungen mit einem breiten Einsatzbereich und daher sehr unterschiedlicher Zusammensetzung.Cleaners are mostly surfactant-containing formulations with a wide range of uses and therefore very different compositions.
Nach pH- Wert unterscheidet man alkalische, neutrale und saure Reiniger, nach der Angebotsform flüssige (auch in Sprayform) und feste Reiniger (auch in Tablettenform). Die sogenannten Reiniger für harte Oberflächen sollen im Unterschied etwa zu Geschirrspülmitteln, die meist auch in die Produktgruppe der Reiniger eingeordnet werden, sowohl im konzentrierten Zustand als auch in verdünnt wässrigen Lösungen in Verbindung mit mechanischer Energie ein optimales Anwendungsprofil zeigen. Kaltreiniger entfalten ihre Leistung ohne erhöhte Temperatur. Maßgebend für die Reinigungswirkung sind vor allem Tenside und/oder Alkaliträger, alternative Säuren, gegebenenfalls auch Lösungsmittel wie Glykolether und niedere Alkohole. Im allgemeinen sind in den Formulierungen darüber hinaus Builder, je nach Reiniger-Typ auch Bleichmittel, Enzyme, keimmindernde oder desinfizierende Zusätze sowie Parfümöle.A distinction is made between alkaline, neutral and acidic cleaners according to the pH value, liquid cleaners (also in spray form) and solid cleaners (also in tablet form). In contrast to dishwashing detergents, which are usually also classified in the product group of detergents, so-called cleaners for hard surfaces should show an optimal application profile both in the concentrated state and in dilute aqueous solutions in conjunction with mechanical energy. Cold cleaners perform without increasing the temperature. The main determining factors for the cleaning action are surfactants and / or alkali carriers, alternative acids, and if appropriate also solvents such as glycol ethers and lower alcohols. In general, there are also builders in the formulations, depending on the type of detergent, bleaching agents, enzymes, germ-reducing or disinfectant additives and perfume oils.
Haushalts-Reiniger können als Universal-Reiniger oder als Spezial-Reiniger für u.a. Keramik, Fliesen, Fenster, Kunststoffe, (Teppich-)Böden, Kochfelder, Backöfen, Mikrowellenherde, als Sanitär-Reiniger oder WC-Reiniger formuliert werden. Rohr- Reiniger sind alkalisch eingestellt und bestehen z.B. aus festem Natriumhydroxid und Aluminium-Pulver. Sanitär-Reiniger enthalten neben Tensid und Builder vor allem keimmindernde Wirkstoffe, wobei das früher verwendete Natriumhypochlorit teilweise durch Wasserstoffperoxid oder andere Persauerstoff-Verbindungen ersetzt ist. Zu den Spezial-Reinigern gehören im Do-it-yourself-Bereich auf Kfz-, Auto- Scheiben-, Felgen-, Motoren- und Farbauftragsgeräte-Reiniger. Technische Reiniger werden vor allem in der Getränke-, Nahrungsgüter-, chemischen, kosmetischen und pharmazeutischen Industrie, aber auch in der Metall- Industrie zum Metall-entfetten eingesetzt. Die Produktgruppe umfasst u.a. auch Reiniger für Kfz- Waschanlagen, Tankwagen- und Flugzeug-Reiniger. Im Hinblick auf die erforderliche Produktivität müssen diese Reiniger mit schaumarmen Tensiden formuliert sein, wofür sich spezielle nichtionische Tenside, wie Ethylenoxid- Propylenoxid-Blockcopolymere und sogenannte endgruppenverschlossene Alkyl- ethoxylate, eignen.Household cleaners can be formulated as universal cleaners or as special cleaners for ceramics, tiles, windows, plastics, (carpeted) floors, hobs, ovens, microwave ovens, as sanitary cleaners or toilet cleaners. Pipe cleaners are alkaline and consist, for example, of solid sodium hydroxide and aluminum powder. In addition to surfactants and builders, sanitary cleaners mainly contain germ-reducing agents, although the sodium hypochlorite previously used is partly replaced by hydrogen peroxide or other peroxygen compounds. The specialty cleaners in the do-it-yourself area include automotive, car, window, rim, engine and paint application cleaner. Technical cleaners are mainly used in the beverage, food, chemical, cosmetic and pharmaceutical industries, but also in the metal industry for metal degreasing. The product group also includes cleaners for car washes, tank truck and aircraft cleaners. In view of the required productivity, these cleaners must be formulated with low-foam surfactants, for which special non-ionic surfactants such as ethylene oxide-propylene oxide block copolymers and so-called end-capped alkyl ethoxylates are suitable.
