C12-22 Alkyl Acrylate/Hydroxyethylacrylate Copolymer is a synthetic acrylic copolymer used in cosmetic formulations to thicken, stabilize emulsions, and adjust viscosity and texture. It functions as a formulation aid rather than a treatment active.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Rare | Occasional transient redness or stinging, typically in sensitive or compromised skin. |
Allergic contact dermatitis | Very rare | Isolated sensitization reports; acrylate polymers are generally considered low-allergenicity. |
Eye irritation | Rare | Possible if formulations come into direct contact with the eyes. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
