Abstract
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: ##STR00001## wherein R.sub.1 has the structural formula: ##STR00002## wherein R.sub.5 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: ##STR00003## wherein R.sub.2, R.sub.3 and R.sub.4 are independently selected from the group consisting of methyl, ethyl, propyl or isopropyl; or ##STR00004## wherein R.sub.6 is H or OH or NH.sub.2 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.
