C12-22 Alkyl Acrylate/Hydroxyethylacrylate Copolymer

C12-22 Alkyl Acrylate/Hydroxyethylacrylate Copolymer is a synthetic polymer — a long-chain molecule made up of repeating units — used primarily as a formulation ingredient rather than an active skincare component. It is designed to bind other ingredients together, stabilise emulsions (mixtures of oil and water), and adjust how a product feels on the skin.This ingredient belongs to a class of polymers commonly used across cosmetics, pharmaceuticals and personal care products. It functions behind the scenes to improve product texture, spreadability and shelf stability rather than to deliver d…

This copolymer works by forming a three-dimensional network within a formula. The polymer chains interact with both water-based and oil-based ingredients, allowing them to coexist in a stable mixture. On the skin, it can form a light, flexible film that helps the product adhere and spread evenly without feeling sticky or heavy.

This ingredient requires no special application technique; you would use it as you would any other skincare product containing it. As it is a background formulation ingredient, its efficacy depends on the overall product design and the active ingredients present alongside it. Store products in a cool place to help maintain stability over time.

Generally well-tolerated in skincare formulations. Rare sensitivity reactions are possible, as with any ingredient, but are not commonly reported.
