POLYGLYCERYL-4 CAPRATE
Is POLYGLYCERYL-4 CAPRATE safe for seborrheic dermatitis?
Polyglyceryl-4 Caprate is context-dependent for seborrheic dermatitis. It helps oils disperse in water and supports mild cleansing or preservation systems, but it is not a seb derm treatment.
Caprate refers to a C10 fatty-acid component, which falls outside the C11 to C24 range used by the practical Malassezia screen checked for this page. Even so, this is an intact polyglyceryl ester rather than free capric acid, and no exact human seb derm or yeast study was found. Treat it as a formula-dependent ingredient and watch how the complete product behaves on inflamed skin.

What is POLYGLYCERYL-4 CAPRATE used for in skincare?
Polyglyceryl-4 Caprate is a polyglycerol ester made with capric acid. Its water- and oil-compatible structure allows it to act as a mild emulsifier, solubiliser and cleansing helper. It is often combined with polyglyceryl caprylates, glyceryl caprylate, humectants and gentle surfactants in micellar waters, cleansers, sprays and light emulsions.
