Ethylene/Propylene/Styrene/Copolymer description

Ethylene/propylene/styrene copolymer is a synthetic polymer used in skin care to help thicken and create gel textures in oil-based formulas. This polymer, or compound with a high molecular weight made up of smaller parts, is created when the hydrocarbons ethylene, propylene and styrene are joined together and then terminated through a process called hydrogenation. Due to its status as a gelling agent, this copolymer improves the sensorial experience of formulas and can help to create an occlusive barrier that prevents transepidermal water loss, ultimately helping hydrate skin. Ethylene/propylene/styrene copolymer is often used alongside butylene/ethylene/styrene copolymer. In cosmetics, it’s often used in levels between 0.5-1.5%. It’s considered safe as used in cosmetics, with amounts double to three times what’s typically used being non-irritating to skin and only mildly irritating to eyes.
