A polymer thickener and stabilizer. It thickens gels and creams and holds actives evenly. Inert to skin.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
A functional thickener. Safe.
Sodium Polymethacrylate (INCI: Sodium Polymethacrylate) is a thickening and stabilizing polymer. It gives body to gels and creams, keeps actives evenly spread, and stops the formula from separating. This is a functional ingredient, not a skincare active. Its job is viscosity and stability, not an effect on skin. No treatment result should be expected from it. Because of its topical use and lack of meaningful systemic uptake, it can be used during pregnancy and breastfeeding without restriction. Tolerance is good. Irritation and allergy potential are both low, so it is comfortable on sensitive skin too. It is an inert material that most skin carries without a reaction.
