Isodecyl Oleate

What is Isodecyl Oleate?

A synthetic ester of isodecyl alcohol and oleic acid, designed to deliver a smooth, emollient skin feel.

Why is it used in products?

It functions as a lightweight emollient and solvent that helps active ingredients penetrate the skin more effectively.

Why does it clog pores?

The oleic acid portion of this ester is a proven pore irritant that disrupts the follicular lining and promotes comedone formation. Its penetration-enhancing properties actually help it deliver this pore-disrupting oleic acid deeper into follicles. This makes it a particularly effective pore-clogger despite its light feel.
