Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone description

Lauryl PEG-9 polydimethylsiloxyethyl dimethicone is a silicone polymer that plays multiple roles in skin care, hair care, makeup, and other hygiene/beauty product formulations. It offers conditioning properties that can help soften skin or hair. It may also be used as a viscosity adjusting agent to enhance the formula’s texture. Other functions include emulsifier and surfactant (cleansing agent). Lauryl PEG-9 polydimethylsiloxyethyl dimethicone may be plant-derived or synthetic. It’s described as colorless to light brown, transparent to slightly hazy liquid. Manufacturers of this ingredient note its good compatibility/solubility with other silicones, oils, and esters. It’s also extolled as part of a blend that enhances the dispersion of mineral sunscreen actives to achieve reliable, uniform UV protection. Lauryl PEG-9 polydimethylsiloxyethyl dimethicone has been deemed safe by the Cosmetic Ingredient Review Expert Panel.
