ABSTRACT:
A soap-free sucrose ester-containing surfactant is obtained by transesterifying sucrose with at least one fatty acid triglyceride to produce a solid material containing sucrose esters, glycerides and fatty acid soaps, and treating this material with a solution of a metal salt in water or an alkanol to produce a second solid material and separating the soap-free product containing sucrose esters by dissolving the esters present in an alkanol and evaporating the alkanolic solution to dryness. Glycerides are removed, where desired, by extracting with an organic solvent.
