Also known as
ABIL EM 90 silicone emulsifier PEG/PPG dimethicone cetyl dimethicone copolyol
Compatibility
Works well with:
cyclopentasiloxane dimethicone mineral oil isohexadecane phenyl trimethicone glycerin
Use caution with:
high levels of ethanol anionic emulsifiers
Works best in water-in-silicone or water-in-oil emulsion systems and is generally incompatible with anionic emulsifiers, which can disrupt the silicone emulsion network. High concentrations of ethanol may destabilize emulsions built with this ingredient. It is often combined with co-emulsifiers such as polyglyceryl-4 isostearate or lauryl PEG-9 polydimethylsiloxyethyl dimethicone for optimal stability.
Formulation notes
Cetyl PEG/PPG-10/1 Dimethicone is a silicone-based emulsifier primarily used to create stable water-in-silicone (W/Si) emulsions, enabling the formulation of lightweight, non-greasy sunscreens, foundations, and skin-care products with a silky skin feel. Its cetyl-modified backbone anchors at the oil-water interface, providing robust emulsion stability and improved water resistance in finished products. Formulators value it for its ability to disperse water-soluble actives evenly within a silicone-continuous phase while delivering a smooth, velvety application texture.
