Abstract

Disclosed are novel polyglycerine polyricinoleates as emulsifiers obtained by the esterification of polyricinoleic acid with a natural condensation rate of from 2 to 10 with a polyglycerine mixture comprising 5-35 wt. % glycerine, 15-40 wt. % diglycerines, 10-30 wt. % triglycerines, 8-20 wt. % tetraglycerines, and 3-10 wt. % pentaglycerines, and the remainder being oligoglycerines. The materials have improved emulsifying capacity.
