Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A complex synthetic polymer used to make products opaque — creates a milky, creamy appearance.
This is a sodium salt copolymer of styrene, methoxy PEG-10 maleate, nonoxynol-10 maleate, and acrylate monomers. It functions as an opacifying agent, providing cosmetic products with a desirable white, creamy appearance. No GHS hazards, no EU restrictions. As a high-molecular-weight polymer, skin penetration is negligible. Contains PEG and nonoxynol moieties with theoretical trace ethylene oxide concerns.
