Also known as
PEG/PPG-20/20 Behenyl Dimethicone silicone PEG/PPG emulsifier dimethicone copolyol behenyl KF-6038
Compatibility
Works well with:
cyclopentasiloxane dimethicone glycerin niacinamide hyaluronic acid phenoxyethanol
Use caution with:
high concentrations of electrolytes strong acids strong bases
This silicone-based emulsifier is well suited for water-in-silicone (W/Si) and water-in-oil emulsions and is compatible with a broad range of silicone fluids and cosmetic actives. High electrolyte concentrations can disrupt emulsion stability, so salt levels should be kept low. Avoid extreme pH conditions which may hydrolyze the polyether grafts.
Formulation notes
Behenyl PEG/PPG-20/20 Dimethicone is a silicone-polyether copolymer grafted with a behenyl (C22) fatty chain that functions primarily as a W/Si emulsifier, enabling the formation of lightweight, silky-feeling emulsions and sunscreens. The long behenyl tail enhances emulsion robustness and can impart a mild thickening effect, while the PEG/PPG backbone provides hydrophilic character. It is widely used in color cosmetics, sun-care formulas, and skin-care products where a non-greasy, smooth skin feel is desired.
