What it is
C30-45 olefin is a synthetic ingredient made up of long-chain hydrocarbon (olefin) molecules. In formulations it behaves like a waxy structuring agent, helping to build body, form a cohesive film, and keep the product stable and evenly textured. It appears in some sunscreens and color cosmetics as a supporting structural ingredient.
Safety & warnings
As an inert, high-molecular-weight hydrocarbon material it is generally well tolerated and not associated with sensitization. Comedogenicity data are limited, but it is typically used at modest levels as a structuring agent.
Origin & sourcing
Synthetic, produced from long-chain olefin hydrocarbons.
Questions everyone asks
What is C30-45 olefin used for?
It is a waxy synthetic ingredient that helps structure the formula, form a film, and keep the product's texture stable and uniform.
Is it the same as a UV filter?
No. It does not provide sun protection; it is a structuring and film-forming ingredient that supports the overall formula.
