Polyglyceryl-10 Pentastearate

A Natural Polyglyceryl O/W Emulsifier

Polyglyceryl-10 Pentastearate is a polyglycerol-ester emulsifier (from glycerin and stearic acid), supplied as a waxy solid — often paired with Behenyl Alcohol and Sodium Stearoyl Lactylate.

It builds gentle, oil-in-water emulsions with a light, natural feel and good tolerance, as a PEG-free emulsifier choice.
