Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer ●
TL;DR. This ingredient is primarily a film-forming and texture-modifying polymer that improves slip, wear, water resistance, and makeup or sunscreen adhesion on skin and hair.
What does Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer do in a cosmetic formula?
This ingredient is primarily a film-forming and texture-modifying polymer that improves slip, wear, water resistance, and makeup or sunscreen adhesion on skin and hair.
Is Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer clean?
From a clean-beauty perspective, it has significant friction because it is a synthetic, organosilicon-modified polymer with low biodegradability. It is not mainly flagged for skin irritation, but for persistence and synthetic-polymer policies in stricter standards.
Is Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer sustainable?
This material is made through petrochemical polymer chemistry with organosilicon components, so it has limited renewable-feedstock alignment. Its high molecular weight and film-forming nature point to poor biodegradability and environmental persistence concerns.
Is Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. It fits Green Chemistry poorly because it relies on synthetic polymerization, non-renewable inputs, and limited biodegradability, even though it can improve product performance at low levels.
How does Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer work chemically?
The molecule is a cross-functional synthetic copolymer with acrylate backbone segments, long hydrophobic alkyl side chains, and organosilicon-modified side chains that create flexible, water-resistant films. It is typically used at low single-digit levels in anhydrous or emulsion systems and is selected for rub resistance, slip, and compatibility with oils, waxes, pigments, and UV-filter phases.
