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.
