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.
Questions everyone asks
