Abstract
The present invention relates to a gelled cosmetic emulsion comprising an oil phase, an aqueous phase and a gelling system which contains at least one non-siloxane based polyamide in a sufficient amount to gel the emulsion. The polyamide can have an tertiary amide, ester, acid, or amine terminal end group. The emulsion is stabilized with an alkylene oxide containing emulsion stabilizer. The polyamide resin is stabilized with a resin stabilizer containing an atom with a certain electronegativity. The emulsions of the present invention are substantially transparent and when colorants are added the color is especially bright and clear. The emulsions are used in lipstick and mascara products as well as other gel and stick products.
