What it is
Sodium Acrylate/Vinyl Alcohol Copolymer is made by polymerizing sodium acrylate together with vinyl alcohol units, producing a water-compatible film-forming polymer. In formulas it helps build viscosity, stabilize emulsions, and lay down a smooth, even film as the product dries. These properties make it useful for improving the texture and wear of sunscreens and other leave-on products.
Safety & warnings
As a high-molecular-weight polymer it is generally well tolerated and considered low risk for irritation or sensitization at cosmetic use levels.
Origin & sourcing
Synthetic: a copolymer produced from sodium acrylate and vinyl alcohol monomer units.
Questions everyone asks
What does this copolymer do?
It acts as a film former, thickener, and stabilizer, helping build viscosity and lay down a smooth, even film.
Is it natural or synthetic?
It is synthetic, made by combining sodium acrylate and vinyl alcohol units into a copolymer.
