Ethylene/Propylene Copolymer
What Ethylene/Propylene Copolymer is & what it does
Ethylene/Propylene/Styrene Copolymer is a synthetic polymer built from ethylene, propylene, and styrene monomers. In cosmetics, including some sunscreens, it is used as a viscosity controlling and texturizing agent that helps thicken and stabilize the formula. A notable property is its oil-compatible nature, which makes it useful for structuring anhydrous or oil-rich bases.
What does Ethylene/Propylene Copolymer do in skincare?
It is a synthetic polymer used mainly as a thickener and texture or viscosity agent. It can help adjust a product's consistency and contribute to a smooth, stable feel. It is an inert film-forming type ingredient rather than a skincare active.
Is Ethylene/Propylene Copolymer natural or synthetic?
It is synthetic. The copolymer is made by combining ethylene and propylene units into a polymer chain. It is a petroleum-derived material rather than a botanical ingredient.
Is Ethylene/Propylene Copolymer safe?
Inert synthetic polymers like this are widely used in cosmetics as texture agents and are generally considered non-reactive on skin. Suitability still depends on the complete formula and individual skin, and we do not provide medical advice. It is not known as a common irritant.
