Abstract
Fatty esters of oligoesters of a dicarboxylic acid and a polyol retaining at least one free hydroxyl group, particularly of the formula (I): R—[ORO—C(O)—R—(O)C—]—R(I), where Ris H, a monocarboxylic acid group, or RO—[C(O)—R—(O)C]—; Rs are residues of polyols having at least one substituent free hydroxyl; Rs are hydrocarbylene; Ris —OH, —OM where M is a salt forming metal, amine or ammonium, —OR, or —ORO—R; Ris Cto Chydrocarbyl; Ris Cto Chydrocarbyl; Ris H, or —C(O)R; and m is 1 to 20; provided that at least one of Rand Ris or includes a Cto Cgroup, are surfactants. A range of surfactant properties can be obtained by varying the molecules within these ranges. Especially where Ris derived from a higher polyol e.g. sorbitol, Ris Cto C, and the fatty terminal group is Cto C, the products can be highly water soluble and effective oil in water emulsifiers.
