    摘要: A novel fatty polypropoxylate ester which is an ester of an aliphatic or an aromatic monoacid formed by reacting the acid with a stoichiometric excess of a polypropoxylated fatty alcohol. The compounds have the following structural formula: wherein R1 is a polypropoxylated fatty alcohol having the structural formula: wherein R5 is a saturated or unsaturated, substituted or unsubstituted aliphatic or aromatic moiety containing from 4 to 24 carbon atoms, and x is an integer from 3 to 30; and wherein R has the structural formula: wherein R2, R3 and R4 are independently selected from the group consisting of methyl, ethyl, propyl or isopropyl; or wherein R6 is H or OH or NH2 or methyl or ethyl. The compounds possess exceptional pigment dispersant and esthetic emollient properties for use in personal care and topical pharmaceutical preparations, e.g., lipsticks, cream foundations, waterproof sunscreens, sunscreen lotions.
