摘要:
Fatty esters of oligoesters of a dicarboxylic acid and a polyol retaining atleast one free hydroxyl group, particularly of the formula (I): R1-[OR2O-C (O)-R3-(O)C-]m-R4 (I), where R1 is H, a monocarboxylic acid group, or R6O-[C(O)-R3-(O)C]-; R2s are residues of polyols having at least one substituent freehydroxyl; R3s are hydrocarbylene; R4 is -OH, -OM where M is a salt formingmetal, amine or ammonium, -OR6, or -OR2O-R7; R5 is C7 to C21 hydrocarbyl; R6is C8 to C22 hydrocarbyl; R7 is H, or -C(O)R5; and m is 1 to 20; provided thatat least one of R1 and R4 is or includes a C8 to C22 group, are surfactants. Arange of surfactant properties can be obtained by varying the molecules withinthese ranges. Especially where R2 is derived from a higher polyol e.g.sorbitol, R3 is C2 to C6, and the fatty terminal group is C8 to C14, theproducts can be highly water soluble and effective oil in water emulsifiers.
