Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer

What Acrylates/Stearyl Acrylate/Dimethicone 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.

What does Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer do in skincare?

This ingredient is a synthetic copolymer used mainly as a film former and to help structure or stabilize a formula. Combining acrylate and silicone (dimethicone) units gives a polymer that can leave a smooth, often water-resistant film on the skin. In sunscreens, film-forming polymers like this can help the product spread evenly and stay put.

Is Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer safe?

Acrylate and silicone copolymers like this are widely used in cosmetics and are generally considered suitable at the levels formulators use. Because it is a large polymer, it tends to sit on the skin surface rather than be absorbed. Individual tolerance can vary, so patch testing a new product is reasonable.

Is Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer vegan?

This is a fully synthetic copolymer made from acrylate and silicone building blocks, so it does not contain animal-derived material and is generally suitable for vegan formulas. Whether a finished product is vegan also depends on its other ingredients. Check the specific brand's labeling to confirm.
