Abstract:
A temperature-stable cosmetic composition including a polyamide resin, a solvent for the polyamide resin, and a gelling agent selected from the group consisting of N-acyl amino acid amides, N-acyl amino acid esters, and mixtures thereof, is disclosed. A composition of the invention can be made translucent or transparent, need not require specialized packaging and containers, is not subject to hardening caused by evaporation of volatile alcohols, is temperature-stable over a period of several weeks, and exhibits excellent esthetic and functional properties, including sensory properties, for consumer acceptance.
Extended wear compositions are disclosed which include the use of silicone resin, a dimethicone solvent, a low viscosity dimethicone dispersant having a viscosity of less than 1,000 cps and a high concentration of colorant or pigments. The resultant low viscosity compositions can be dispensed with a felt tip applicator and still provide extended wear qualities.

Abstract:
A plasticized high water content cosmetic gel that will be sharpenable when used as a core inside of a sharpenable pencil barrel. The gel essentially comprises, by weight, about 25-42% water; about 25-35% of a polyol or aliphatic diol vehicle such as a butylene glycol; about 4-12% sodium stearate; about 0. 1-2% of a carboxylated acid ester plasticizer; about 4-28% of a colorant; and about 0. 1-1% of a surfactant. To reduce syneresis, adding about 1 percent or less a viscosity increasing agent is effective. For water resistance when the cosmetic gel is applied to a user's skin, adding about 5-10% of a styrene acrylic polymer waterproofing agent is effective, and does not increase irritation levels out of the mild range.
