ALLYL STEARATE/VA COPOLYMER ●
TL;DR. This ingredient is a synthetic film-former that helps create flexible, water-resistant coatings in color cosmetics, sunscreens, and hair or skin styling products. It can also improve adhesion, gloss, and wear in anhydrous or solvent-based formulas.
What does ALLYL STEARATE/VA COPOLYMER do in a cosmetic formula?
This ingredient is a synthetic film-former that helps create flexible, water-resistant coatings in color cosmetics, sunscreens, and hair or skin styling products. It can also improve adhesion, gloss, and wear in anhydrous or solvent-based formulas.
Is ALLYL STEARATE/VA COPOLYMER clean?
From a clean-beauty perspective, this ingredient is often treated as a synthetic polymer with restricted-list friction, especially where brands screen for persistent microplastic-like materials. Skin irritation is not usually the main concern, but residual manufacturing impurities and polymer persistence can affect its acceptability.
Is ALLYL STEARATE/VA COPOLYMER sustainable?
This material is typically made from synthetic feedstocks with limited renewable input. It is expected to biodegrade slowly, so its sustainability profile is weaker than readily biodegradable waxes, oils, or natural film-formers.
Is ALLYL STEARATE/VA COPOLYMER COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic standards because it is a synthetic polymer outside the permitted natural and nature-derived ingredient framework. It fits poorly with Green Chemistry priorities around biodegradability, renewable sourcing, and end-of-life simplicity.
How does ALLYL STEARATE/VA COPOLYMER work chemically?
The molecule is a hydrophobic copolymer with long C18 fatty side chains and polar acetate-type repeat units, which helps it form flexible, water-resistant films. It is generally used in low percentages as a film-forming or wear-enhancing additive and is more compatible with oils, esters, and organic solvents than with water-based systems.
