ANHYDRIDE COPOLYMER ●
TL;DR. This ingredient is primarily a film-former and binder. It helps create a continuous layer on skin, hair, or nails for hold, adhesion, water resistance, or longer wear.
What does ANHYDRIDE COPOLYMER do in a cosmetic formula?
This ingredient is primarily a film-former and binder. It helps create a continuous layer on skin, hair, or nails for hold, adhesion, water resistance, or longer wear.
Is ANHYDRIDE COPOLYMER clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic polymer rather than a readily biodegradable, naturally derived material. Dermal penetration is expected to be low due to high molecular weight, but residual monomers and polymer persistence are the main review points.
Is ANHYDRIDE COPOLYMER sustainable?
This material is typically made from petrochemical feedstocks and is not considered readily biodegradable. Its end-of-life profile is the main sustainability concern, especially when it enters wastewater as a persistent polymeric residue.
Is ANHYDRIDE COPOLYMER COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic standards because it is a petrochemical synthetic polymer with poor biodegradability alignment. It fits Green Chemistry only weakly, with efficient performance at low levels but limited renewable sourcing and end-of-life compatibility.
How does ANHYDRIDE COPOLYMER work chemically?
The molecule is a high-molecular-weight synthetic copolymer containing cyclic carboxyl-derived reactive groups that can hydrolyze toward acid functionality in water. Use levels are typically in the low single digits for film formation, and performance depends on pH, neutralization state, solvent system, salts, and compatibility with cationic ingredients.
