Abstract
Abstract This invention provides skin care compositions which include an emollient complex containing a primary moisturizing agent selected from certain carboxylic acid amides and a mucopolysaccharide secondary moisturizing agent. The compositions also include one or more skin-structuring proteins and an astringent agent which confers skin-firming characteristics. Long lasting protection is afforded by the optional incorporation of a cellulosic film-former. Preferred embodiments take the form of two discrete gel phases.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
87 words
Skin treatment compositions comprising: 0.25-10% of a primary moisturizing agent selected from gluconamides containing at least 6 carbon atoms; 0.2-2% of a mucopolysaccharide moisturizer containing disaccharide repeating units; 0.05-8% of a skin-structuring protein selected from the group consisting of glycoproteins, collagen, striated muscle fiber, elastin, and reticulin; and 0.1-5% of an astringent agent selected from the group consisting of arnica flowers or extracts hereof, methanol, lower alkyl alcohol, boric acid, lactic acid, methol, camphor, zinc phenol sulphonate, and zinc chloride or sulfate; in a cosmetically acceptable carrier.
