ABSTRACT:
Process for preparing polyglycerolated nonionic surfactants from (poly)hydroxylated organic compounds, by condensing glycerol monochlorohydrin with the said (poly)hydroxylated compound in the presence of a strong base, at a temperature below 150.degree. C. and in the presence of an aromatic solvent, removing the water formed by distillation as it forms.
This process makes it possible to condense a relatively large quantity of glycerol monochlorohydrin in a single step, while limiting the formation of polyglycerols, and to obtain a good quality surfactant which is usable in cosmetic compositions.
