Polyglyceryl-6 Stearate

INCI: Polyglyceryl-6 Stearate

Polyglyceryl-6 stearate is a PEG-free emulsifier derived from the esterification of hexaglycerol (a polymer of six glycerol units) with stearic acid. It enables oil and water phases to mix into stable emulsions and is particularly suited to low-viscosity formulations such as serums, lotions, and sprays. It is based on renewable raw materials and is considered a gentle, modern alternative to PEG-based emulsifiers.
