Copolymer

What Copolymer is & what it does

Copolymer is a general term for a polymer built from two or more different monomer units linked into long chains. In skincare and sunscreen formulas, copolymers are used for many purposes, such as forming films, thickening, stabilizing emulsions, or improving water and rub resistance. The exact role depends on the specific copolymer, so its function varies from product to product.

What does a copolymer do in skincare?

A copolymer is a polymer built from two or more different building blocks, and its job depends on the specific type. In skincare and sunscreens, copolymers are commonly used to form films, thicken, stabilize emulsions, or improve water and rub resistance. Because Copolymer is a broad term, the exact role varies by product.

Is a copolymer natural or synthetic?

Most copolymers used in cosmetics are synthetic, made by linking selected monomers into long chains, though some are based on naturally derived units. Since Copolymer is a general category, the source depends on the specific polymer in a given formula. Check the full ingredient list for the precise copolymer named.

Is a copolymer safe?

Copolymers are used widely in cosmetics, largely as film formers and texture agents, and established cosmetic copolymers are generally considered safe as used. Because the term covers many different materials, safety relates to the specific copolymer in a product. If you have sensitive skin, patch testing the finished product is wise.
