Ethylene/Propylene/Styrene Copolymer
Ethylene/Propylene/Styrene Copolymer
A synthetic elastomeric polymer used to gel oils and add body to anhydrous sticks and balms.
What it does
Ethylene/Propylene/Styrene Copolymer is a rubbery synthetic polymer soluble in oils. It thickens and gels the oil phase, helps hold a stick or balm together, and improves the glide and structure of the formula. It is a texture-and-structure ingredient rather than a skin active.
