Formula IngredientViscosity ControllerEthylene/Propylene/Styrene Copolymer
INCI: Ethylene/Propylene/Styrene Copolymer
Ethylene/propylene/styrene copolymer is a hydrogenated synthetic polymer of ethylene, propylene, and styrene monomers. It functions primarily as an oil gelling agent and viscosity controller. When combined with its related compound butylene/ethylene/styrene copolymer and mixed with hydrocarbons, it creates gels with varying sensorial and physical characteristics, improving skin occlusivity and reducing transepidermal water loss.

Is Ethylene/Propylene/Styrene Copolymer safe? Key considerations
Can Ethylene/Propylene/Styrene Copolymer cause irritation?
Low RiskEWG rates this ingredient at 1 (lowest hazard). CIR (Cosmetic Ingredient Review) gives it an A rating (highest safety). No EU CosIng Annex II or III restrictions apply. As an inert polymer, it has minimal direct skin interaction.
Does Ethylene/Propylene/Styrene Copolymer increase sun sensitivity?
No RiskDoes not increase photosensitivity. No special sun protection measures are required.
Is Ethylene/Propylene/Styrene Copolymer safe during pregnancy?
SafeNo specific pregnancy concerns noted in available safety databases. As an inert synthetic polymer with no known systemic absorption, it is generally considered safe during pregnancy.
