摘要:
A natural ester for topical application to the skin, hair, and/or nails comprising the esterification product of (1) an undecylenic acid derived from a natural source and (2) a vegetable-derived fatty alcohol, and a personal care product that contains this ester is provided. Also disclosed are methods of preparing a natural personal care composition comprising combining an ester and at least one personal care component, wherein the ester comprises the esterification product of (1) an undecylenic acid derived from a natural source and (2) a vegetable-derived fatty alcohol.
摘要:
The invention includes a method of increasing the substantivity of a personal care composition to hair, skin or nails by preparing a composition of an aqueous phase, a non-aqueous phase and a neutralized amino acid ester that is a reaction product of a neutral amino acid having a non-polar side chain with a long chain fatty alcohol and is represented by formula (I):
wherein R 1 is an alkyl group;R 2 is a linear or branched carbon chain; and the amine group of the amino acid is neutralized with an acid. The composition is substantially free of petrochemicals and/or derivatives of petrochemical materials. The aqueous phase and the non-aqueous phase are emulsified by the neutralized amino acid ester. Other methods and an emulsifiers that is the neutralized amino acid ester are included. Because the neutralized amino acid ester and the compositions do not contain petrochemical-derived ingredient, the products are natural.

摘要:
A UV absorbing complex polyol polyester polymer is the product of a reaction scheme that includes: (i) the esterification of a polyol and a dianhydride, wherein the esterification is carried out under conditions that facilitate substantially only anhydride opening, to form a polyester polymer comprising at least two pendant carboxylic groups, and at least two hydroxyl groups: and (ii) the reaction of at least one pendant carboxylic group and at least one terminal hydroxyl group of the polyester polymer with an epoxide having a functional group, wherein the epoxide comprises an UV absorbing moiety. A crosslinked UV absorbing complex polyol polyester polymer that is reaction product of a random copolyesterification esterification reaction and/or the esterification product.
