C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer

What C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer is & what it does

C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer is a synthetic crosslinked polymer made from acrylate and methacrylic acid units with C8 to C22 alkyl side chains. In cosmetic and sunscreen formulas it functions as a film former, thickener, and stabilizer, helping the product hold together and stay evenly distributed. A notable trait is its ability to improve water resistance and the long-wear feel of emulsions.

What does C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer do in skincare?

This crosspolymer acts as a film former, thickener, and stabilizer in cosmetic and sunscreen formulas. It helps the product hold together, stay evenly mixed, and form a thin, even film on the skin. In sunscreens it can contribute to better water resistance and longer wear.

Is C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer safe?

C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer is a large synthetic polymer used in cosmetics and is generally regarded as safe for topical use at typical levels. Because it is a high-molecular-weight film former, it stays on the skin surface rather than being absorbed. Anyone with sensitive skin can patch test a new product to be sure.

Is C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer natural or synthetic?

It is synthetic. The ingredient is a man-made crosslinked polymer built from acrylate and methacrylic acid units, not sourced from a plant or animal. As a result it is typically suitable for vegan formulas.
