What is Acrylates Copolymer?

Acrylates Copolymer is a group of compounds made from acrylic acid and its esters. It is produced through a chemical polymerization process that forms long-chain molecules with varying properties depending on the specific formulation.

This ingredient is primarily used in cosmetics and personal care products for its film-forming and adhesive properties. It provides texture, stability, and help to retain moisture on the skin or hair. The health evidence on acrylates copolymer is limited, but it is generally considered safe for topical use in the concentrations typically found in these products.

When you see acrylates copolymer on a label, it's usually indicating a purpose related to improving product feel, longevity, or moisture retention, rather than an active ingredient with specific health effects.

Commonly found in: Whitening products, Makeup, Hair Care, Body Care

Scout's take

Synthetic film-forming acrylate polymer; classified as a primary microplastic by the EU Chemicals Agency (ECHA). Restricted in EU rinse-off cosmetics under the 2023 microplastic regulation phase-in.

More from Scout's analyses

Synthetic polymer film-former — microplastic-adjacent.

from the analysis of equate Timeless White Whitening Strips

Acrylates copolymer is a thickening agent that helps maintain the structure of the strip. However, it is a synthetic polymer that may pose risks of irritation and is not biodegradable, raising environmental concerns.
