Ethylene/Propylene Copolymer

Ethylene/Propylene Copolymer is a synthetic plastic made from two petroleum derived building blocks, ground into fine particles that bulk up scrubs and mascara or help control the texture and gloss of a formula. It falls under a CIR review of vinyl type and related polymers, which reported very low residual monomer levels and concluded the polyene group ingredients are safe in the practices of use described.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
