Ammonium Acryloyldimethyltaurate/VP Copolymer is a synthetic acrylic copolymer used in skincare to thicken, gel, and stabilize emulsions, providing viscosity control and a smooth texture. It functions as a rheology modifier and film former rather than a biologically active treatment ingredient.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Rare | Occasional reports, generally well tolerated on intact skin. |
| Contact allergy/sensitization | Very rare | Polymeric structure makes sensitization uncommon; isolated case reports only. |
| Transient stinging on sensitive skin | Very rare | Usually related to overall formulation rather than the polymer itself. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
