Acrylates/C10-30 Alkyl Acrylate Crosspolymer

Low risk

FunctionThickener

What it is — Acrylates/C10-30 Alkyl Acrylate Crosspolymer (INCI of the same name), a synthetic cross-linked polymer.

What it does — It is commonly used as a thickener and stabilizer that gives gels, lotions and creams their body and helps keep oil and water phases evenly suspended.

Typical use — Found across a wide range of leave-on and rinse-off products where a smooth, structured texture is wanted.

Who it suits / good to know — Suitable for most skin types; it is an inert texture agent that works on the formula rather than the skin.

Safety — Rated low risk as a large, non-penetrating polymer. This is general information, not medical advice; finished products can be patch-tested if your skin is easily irritated.

Why we grade it Low: Low risk — inert texture agent.
How grades are set — Risk reflects our own reading of publicly available safety data, an EWG-style reading shown at the worst-case grade we've assigned this ingredient across products. It isn't a third party's proprietary score, and it isn't medical advice. Always read the packaging and patch-test where indicated.
