C30-38 Olefin/Isopropyl Maleate/Ma Copolymer

What C30-38 Olefin/Isopropyl Maleate/Ma Copolymer is & what it does

C30-38 Olefin/Isopropyl Maleate/MA Copolymer is a synthetic film-forming copolymer made from long-chain olefins reacted with maleic acid esters. In sunscreens and other cosmetics it acts as a thickener and binder that helps hold oils and UV filters in a uniform layer on the skin. A notable property is its ability to improve the water resistance and wear of an applied film.

What does C30-38 Olefin/Isopropyl Maleate/MA Copolymer do in skincare?

This copolymer is a film former and thickener. In sunscreens and other products it helps hold oils and UV filters in an even layer and can improve how well the film resists water and wear. It mainly affects the texture and durability of the formula rather than acting on the skin directly.

Is C30-38 Olefin/Isopropyl Maleate/MA Copolymer safe?

This is a synthetic copolymer used as a structural and film-forming ingredient in cosmetics, and large polymers of this type are generally considered well tolerated on skin. It is not known as a common irritant at typical use levels. If you have sensitive skin, a patch test is a reasonable precaution.

Is C30-38 Olefin/Isopropyl Maleate/MA Copolymer natural or synthetic?

It is synthetic. The ingredient is made by reacting long-chain olefins with maleic-acid based esters to form a copolymer. It is produced for its film-forming and thickening behavior rather than sourced from a plant or animal.
