What it is
This ingredient is derived from the unsaponifiable portion of olive oil, the fraction that does not form soap on treatment with alkali and is rich in sterols and other minor lipids, which is then hydrogenated for stability. In sunscreens and creams it functions as a conditioning emollient that supports a smooth, soft skin feel. It is typically used at modest levels as a specialty olive-derived lipid.
Safety & warnings
Olive-derived unsaponifiables are generally well tolerated and are often chosen for conditioning, comforting effects in leave-on products. As an olive-derived lipid material it is an emollient, so very acne-prone users may prefer lighter ingredients, but it is not a recognized fragrance allergen.
Origin & sourcing
It is a plant-derived material obtained by isolating the unsaponifiable fraction of olive oil (Olea europaea) and hydrogenating it to improve stability.
