INCI: Polyglycerin-6
Polyglyceryl-6 (INCI: Polyglycerin-6) is a synthetic polymer composed of six linked glycerol units, also known as hexaglycerin. It functions primarily as a humectant, attracting and retaining water at the skin's surface to improve hydration and create a plumper appearance. It is also used as an emulsifier backbone for polyglyceryl-6 fatty acid esters, and is valued for its mild, PEG-free, vegetable-derived profile.
