Ammonium Acryloyldimethyltaurate/Carboxyethyl Acrylate Crosspolymer is a synthetic crosslinked acrylic polymer used to thicken, stabilize emulsions, and provide a smooth gel texture in skincare and cosmetic formulations. It functions as a rheology modifier and emulsifier rather than a biologically active treatment ingredient.

| Contact allergy / sensitization | Very rare | Isolated reports; the polymer is generally considered low-sensitizing. |
| Eye irritation | Rare | Possible mild irritation with direct ocular contact in some formulations. |
