Abstract
The invention discloses novel polyester emulsifiers. Compounds of the invention are made by reacting (a) a dimethicone copolyol, (b) a diacid and (c) a fatty alcohol alkoxylate containing 4 to 20 carbon atoms. The compounds of the invention by virtue of (a) the silicone group, (b) the fatty alcohol terminal group and (c) the polyoxyalkylene present in the compound are extremely efficient emulsifiers for a variety of oils at heretofore unknown levels.
