PEG-8 Cetyl Dimethicone
What is PEG-8 Cetyl Dimethicone?
PEG-8 Cetyl Dimethicone is a synthetic hybrid ingredient combining silicone chemistry with polyethylene glycol modification. It features a cetyl dimethicone polymer chain—derived from dimethicone (polydimethylsiloxane) with a cetyl alcohol side chain—ethoxylated with eight units of ethylene oxide (PEG-8). This structure imparts amphiphilic properties, making it dispersible in water while retaining silicone's occlusive benefits. Primarily used in leave-on skincare products like moisturizers, serums, and foundations, it acts as a skin conditioning agent by forming a lightweight film that enhances texture and aids even application. The PEG chain boosts emulsification, helping blend oil and water phases for stable formulations without greasiness. Its low molecular weight modification supports quick absorption and a non-tacky finish on skin surfaces.
