What does this crosspolymer do in skincare?

Ammonium Acryloyldimethyltaurate/Beheneth-25 Methacrylate Crosspolymer is a synthetic polymer used as a thickener and stabilizer. It helps gels, creams, and lotions reach the right consistency and stay evenly mixed. It also contributes to a smooth, cushioned texture rather than acting on the skin itself.

Is this crosspolymer safe?

This crosspolymer is a large polymer molecule used at low levels in cosmetics, where it functions mainly as a texture and stability agent. Such polymers generally stay on the skin surface and are considered well tolerated in typical formulas. As with any ingredient, individual sensitivities can occur.

Is this crosspolymer natural or synthetic?

It is a synthetic ingredient, manufactured by linking acrylate-based and methacrylate-based units into a cross-linked polymer network. It is not derived from a single plant or animal source. Being synthetic, it is normally suitable for vegan formulations.
