Acrylates/Ammonium Methacrylate Copolymer

What Acrylates/Ammonium Methacrylate Copolymer is & what it does

A synthetic thickener that builds clear gels and stabilizes emulsions, giving a smooth, non-greasy texture. It helps suspend ingredients evenly without adding oiliness.

Is Acrylates/Ammonium Methacrylate Copolymer safe?

Acrylates/Ammonium Methacrylate Copolymer is a synthetic film-forming polymer used in cosmetics and is generally considered suitable for topical use at formula levels. Large polymers like this tend to remain on the skin surface rather than being absorbed. Sensitivity is uncommon, but a patch test is sensible if your skin reacts easily.

What does Acrylates/Ammonium Methacrylate Copolymer do in skincare?

Acrylates/Ammonium Methacrylate Copolymer works as a film former and can also help thicken or stabilize a formula. It creates a flexible film on the skin that can improve water resistance and how long a product lasts on the skin. In sunscreens this kind of polymer supports durability and wear.

Is Acrylates/Ammonium Methacrylate Copolymer natural or synthetic?

Acrylates/Ammonium Methacrylate Copolymer is synthetic. It is a man-made polymer built from acrylate and ammonium methacrylate monomers rather than being plant or animal derived. Synthetic copolymers like this are chosen for their reliable film-forming behavior.
