Overview
Polyglyceryl-2 sesquicaprylate is the esterification product of polyglycerin (with two glycerol units) and caprylic acid (octanoic acid). It is a non-ionic surfactant and emulsifier with mild surface-active properties, making it suitable for gentle cleansing and emulsification in personal care and cosmetic formulations. Its low irritation profile makes it ideal for sensitive skin, baby care products, and natural cosmetic lines. The compound is biodegradable and environmentally friendly.
