Plasticized cosmetic gel composition with high water content and pencil containing it

摘要

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.
