Sodium Acrylates Copolymer

Sodium Acrylates Copolymer is a synthetic acrylate-based polymer used in sunscreens and skincare as a thickener and stabilizer that helps control texture and suspend ingredients.

What it is

This is a synthetic copolymer made from neutralized acrylic acid derivatives that swells in water to build viscosity and structure. It is widely used to thicken aqueous phases, stabilize emulsions, and improve the spread and feel of lotions and gels. In sunscreens it helps create an even, cohesive layer and can support a lightweight, non-greasy texture.

Safety & warnings

Acrylate copolymers of this type are large molecules that are not appreciably absorbed and are generally well tolerated with low irritation potential in cosmetic use.

Origin & sourcing

Synthetic; manufactured from acrylic acid derivatives.
