Composition in the form of anhydrous gel with organically modified clay, spongy thermoplastic hollow particles and wax-free fatty phase containing pyrogenic silica, and use for topical application

摘要

A compsn. in the form of an anhydrous fatty phase gel contains in a fatty phase, free from wax, (a) an organo-modified clay, (b) hollow, thermoplastic, expanded particles of (co)polymer formed from ethylenically unsatd. monomer(s), and (c) a pyrogenic SiO2. Pref. the fatty phase forms 60-85 wt. % of the compsn., and contains a plant, mineral, synthetic or silicone oil, a phenylated or hydroxylated silicone gum, and/or a fluorinated oil. The component (a) forms 0.5-6 % of the active matter in the compsn., and is the prod. of reaction of a hectorite or montmorillonite and a quat. ammonium salt, esp. stearyldimethylbenzylammonium chloride (I) or a chloride of formula R-N+)CH3)2-R' Cl- (R, R' = mixt. of 14-200 alkyl gps. derived from hydrogenated tallow). The modified clay is as a gel in a plant, mineral, animal or synthetic oil and a wetting agent, esp. in a mixt. of triglycerides of capric and caprylic acids and propylene carbonate.
