Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer

What this ingredient generally does
A copolymer that thickens the formula, keeps the oil and water parts from separating, and forms a film as it dries. It also helps make the product look opaque and stops it from caking. In short, it sets the texture and holds the mix together.
