What it is
This ingredient is a modified silicone built on a dimethicone backbone carrying both cetyl (fatty) and glyceryl groups, giving it the amphiphilic structure needed to act as an emulsifier. It is used to create and stabilize water-in-silicone or water-in-oil emulsions, which are common in long-wearing sunscreens, primers, and foundations. It helps produce smooth, even textures and supports uniform dispersion of pigments and mineral filters.
Safety & warnings
Silicone emulsifiers of this class are generally considered mild and well tolerated, with low irritation and sensitization potential at normal use levels.
Origin & sourcing
Synthetic silicone-based emulsifier.
Questions everyone asks
What is this ingredient for?
It is a silicone emulsifier that helps blend water and silicone or oil phases into a stable, smooth product, common in long-wearing sunscreens and makeup.
Is it a silicone?
Yes. It is a dimethicone modified with fatty and glyceryl groups so it can act as an emulsifier rather than just a conditioning silicone.
