Hydrogenated Olive Oil Unsaponifiables

Hydrogenated olive oil unsaponifiables are the non-saponifiable fraction of olive oil that has been hydrogenated to increase stability. During oil processing, unsaponifiables are the components that don't convert into soap when treated with alkali—this fraction typically contains sterols, squalene, and polyphenols from the olive.In skincare and haircare formulations, this ingredient functions as an emollient and conditioning agent, helping to soften and smooth the skin surface and improve the feel of hair. It's used in a relatively small proportion of products, appearing in roughly 0.6% of …

Hydrogenated olive oil unsaponifiables work primarily as a humectant and emollient. The lipid and sterol components have an affinity for the skin's outer layers, where they help reduce trans-epidermal water loss and create a light occlusive layer without a heavy or greasy feel.Because the oil has been hydrogenated, it remains stable in formulations and less prone to oxidation than raw olive oil, making it more suitable for shelf-stable skincare products.

This ingredient is typically part of a finished formulation rather than used standalone. Follow the usage instructions of your product; if it's a moisturiser or conditioning treatment, apply to clean skin or damp hair as directed. No special activation or layering technique is required.

Generally well-tolerated and safe for topical use. Some individuals with fungal acne concerns may wish to check product formulations, as plant oils can occasionally feed certain fungal species, though hydrogenation may reduce this risk.
