Acrylates/Ammonium Methacrylate Copolymer ●
TL;DR. This ingredient is a synthetic film former and binder that helps products form a flexible, continuous coating on skin, hair, or lashes. It is used to improve adhesion, wear time, water resistance, and styling hold.
What does Acrylates/Ammonium Methacrylate Copolymer do in a cosmetic formula?
This ingredient is a synthetic film former and binder that helps products form a flexible, continuous coating on skin, hair, or lashes. It is used to improve adhesion, wear time, water resistance, and styling hold.
Is Acrylates/Ammonium Methacrylate Copolymer clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic persistent polymer and may be screened for residual monomers. It is generally low-irritation on skin when well purified, but its polymer profile places it on many restricted-list watch areas.
Is Acrylates/Ammonium Methacrylate Copolymer sustainable?
This material is typically made from fossil-derived feedstocks and is not considered readily biodegradable. Its high molecular weight limits skin penetration, but environmental persistence after rinse-off or removal is the main sustainability concern.
Is Acrylates/Ammonium Methacrylate Copolymer COSMOS-approved?
This ingredient is not aligned with COSMOS natural or organic standards as a conventional synthetic petrochemical polymer. It has weak Green Chemistry alignment because renewable sourcing and biodegradation are limited, even though it can be effective at low use levels.
How does Acrylates/Ammonium Methacrylate Copolymer work chemically?
The molecule is a high-molecular-weight anionic copolymer with pendant ester and ammonium salt groups, designed to dry into a cohesive film. It is typically supplied as an aqueous dispersion or solution, and performance depends on neutralization state, solids content, plasticizers, and compatibility with salts, pigments, waxes, and other polymers.
