Polyglyceryl-4 Laurate is a nonionic surfactant and emulsifier derived from lauric acid and polyglycerin. It is widely used in personal care and cosmetic formulations for mild cleansing, emulsifying, and skin-conditioning properties. This ingredient helps stabilize oil-in-water emulsions, improves texture, and provides a smooth, soft skin feel. Its biodegradable and skin-friendly nature makes it suitable for natural and sensitive-skin formulations.
