What it is
Polyacrylate Crosspolymer-11 is a synthetic crosslinked polymer of acrylate monomers used to thicken and stabilize emulsions and to build a smooth, soft-focus texture. It helps suspend particles, control flow, and impart a velvety, fast-absorbing finish, which makes it common in tone-up and finishing sunscreens. It is used at low to moderate levels as a rheology modifier and film former rather than as an active ingredient.
Safety & warnings
Polymeric rheology modifiers of this type are generally considered low-irritant and non-sensitizing, as the large crosslinked molecules are not appreciably absorbed. They are not associated with comedogenicity at typical use levels.
Origin & sourcing
Synthetic, produced by polymerization of acrylate-type monomers with a crosslinking agent to form an insoluble, swellable polymer network.
Questions everyone asks
What does Polyacrylate Crosspolymer-11 do?
It thickens and stabilizes the formula and helps create a smooth, soft, fast-absorbing texture, especially in tone-up and finishing sunscreens.
Is it a natural ingredient?
No. It is a synthetic crosslinked acrylate polymer made specifically as a texture and stability aid.
