Abstract
Blends of the hard wax fraction obtained from the fractionation of lanolin and an ester derived from an aliphatic polyol or ether polyol and fatty acid are suitable substitutes for U.S.P. anhydrous lanolin and can be substituted therefore in cosmetic formulations (creams, lotions, etc.) without detracting from the properties of the system.
Claims9
A composition useful as a substitute for anhydrous lanolin U.S.P. consisting essentially of:
- a. a hard wax fraction obtained from the fractionation of lanolin and melting in the range of 45.degree.-60.degree. C;
- and
- b. an ester or partial ester of an aliphatic polyol containing from 2 to 20 carbon atoms or an ether polyol obtained by the condensation of from 2 to 8 of said aliphatic polyol units and an aliphatic monocarboxylic acid containing from about 8 to 20 carbon atoms, said ester or partial ester being a liquid at 25.degree. C or lower;
- and said composition containing from about 30 to 70% by weight of component (a) and 30-70 weight percent of component (b).
