Not Clean
Silicones and siloxanes, dimethyl, dodecyl methyl, polymers with alpha-2-propenyl-omega-2-propenyloxypoly(oxy1,2-ethanediyl) (15 mol EO average molar ratio) Science: Process: Ethoxylation | Functions: Light Stabilizer, Viscosity Controlling Safety Ratings: CIR: Safe as used EU Restriction: III/186
Form
Liquid
Plant-Derived
Synthetic. Derived from silicone polymers and polyethylene glycol (PEG) starting materials, both synthetically produced chemicals.
Synthesized through crosslinking of dimethicone with ethoxylated lauryl alcohol via polymerization reactions.
Function
Light Stabilizer | Viscosity Controlling
Benefits
Shields from UV damage
Traditional Use
A modern synthetic polymer developed in the late 20th century combining polyethylene glycol, silicone, and lauryl alcohol. Designed to create lightweight, non-greasy textures and improve the feel of cosmetic formulations.
