Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer

What Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer is & what it does

A pre-neutralized thickener that quickly builds smooth gels and stabilizes emulsions with a silky feel. It is robust and easy to formulate with.

What is Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer and what does it do in sunscreen?

It is a thickener and stabilizer that builds a smooth gel and holds the oil and water parts of a lotion together. Because it comes pre-neutralized, it works quickly and gives products a light, silky texture without needing extra balancing steps. It is what gives many sunscreens their easy-to-spread, gel-cream feel.

Is Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer safe?

Yes. It is a large polymer that stays on the surface and works on the texture of the formula, not on the skin itself, and it is well tolerated in leave-on products. Thickeners like this are a routine, non-controversial part of modern lotions and gels. It is not a common irritant.

Does Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer clog pores?

No. It is a water-loving thickener, not an oil or wax, and it is considered non-comedogenic. Its job is to gel and stabilize the formula, so it has little potential to block pores. If a product breaks you out, the oils and emollients elsewhere are the more likely cause.

What is this ingredient also called on a label?

On an ingredient list it appears under its full INCI name, Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer. It belongs to a family of pre-neutralized acrylate thickeners that formulators often refer to by their trade names. It usually sits in the middle of the list, where the texture-building ingredients live.

Is Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer natural or synthetic?

It is synthetic. It is a lab-made copolymer designed to build smooth gels and stabilize emulsions reliably. It contains no animal-derived material, so it is suitable for vegan formulas.
