Skin Benefits

Creates a cushioned, low-tack feel while increasing staying power. Helps products resist movement for a tidier look through the day.

Uses In Skincare & Cosmetics

Used in lip balms, cream eyeshadows, and transfer-resistant mascaras to build flexible textures and hold oily phases in place.

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Considered low risk for irritation and sensitization, with limited skin penetration. Suitable for long‑wear and waterproof formats when properly formulated.

Is Ethylene/Propylene/Styrene Copolymer a Good Ingredient?

Good: creates flexible, low-tack films that improve staying power and oil gelling, and is typically non-irritating as an inert elastomeric polymer. Since it works purely on texture and wear rather than skin condition, it rates Good rather than Great.
