What it is
Bis-butyldimethicone polyglyceryl-3 is a silicone polymer modified with polyglycerol groups, giving it both oil-loving silicone segments and water-compatible glyceryl segments. This structure lets it act as an emulsifier that helps blend water and oil phases and as a dispersing aid for mineral pigments and UV filters in sunscreens and makeup. It contributes to a stable, even, and smooth-applying product.
Safety & warnings
Silicone polyglyceryl emulsifiers of this type are generally well tolerated and non-irritating in cosmetic use. It is not a recognized fragrance allergen.
Origin & sourcing
It is a synthetic material based on a dimethicone (silicone) backbone functionalized with polyglycerol groups.
