New oil components for cosmetic and pharmaceutical applications consist of reaction products of epoxidized triglyceride oils with monohydric alcohols containing from 1 to 4 carbon atoms. The oil components are produced by reacting an epoxidized triglyceride oil containing from about 4 to about 8% by weight of epoxide oxygen, preferably an epoxidized soya bean oil containing from about 6 to about 7% by weight of epoxide oxygen, in the presence of an acidic catalyst with a monohydric C.sub.1 -C.sub.4 -alcohol, preferably methanol, in excess at the boiling temperature of the alcohol until the oxirane rings have been completely opened, followed by neutralizing the catalyst and distilling off the excess alcohol. The new oil components are eminently suitable, inter alia, for the production of cosmetic stick preparations.
In a method for treating the human skin, mucous membrane, or hair by applying thereto a cosmetic or dermatological preparation which contains an oil component, the improvement wherein the oil component is at least one reaction product of an epoxidized triglyceride oil and a C.sub.1-4 monohydric alcohol.
In a cosmetic preparation in stick form containing at least one wax component wherein said at least one wax component is one or more of beeswax, carnauba wax, and candelilla wax, and at least one cosmetic oil, the improvement wherein the cosmetic oil comprises from about 5 to about 60% by weight of at least one reaction product of an epoxidized triglyceride oil and a C.sub.1-4 monohydric alcohol.
