Cetearyl Dimethicone/Vinyl Dimethicone Crosspolymer is a silicone-based crosspolymer used in cosmetic formulations as an emollient, thickening agent, and film former that imparts a smooth, silky skin feel and helps stabilize emulsions. It is a formulation/base ingredient rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation | Rare | Silicone crosspolymers are generally considered low-irritation; mild reactions are infrequent. |
Contact dermatitis/allergic reaction | Very rare | Sensitization to dimethicone-based ingredients is uncommon and poorly documented. |
Clogged pores/comedogenicity | Rare | Generally regarded as non-comedogenic, though heavy occlusive films may rarely contribute in acne-prone skin. |
