Phytosteryl Oleate ●
TL;DR. This ingredient is a lipid emollient and skin-conditioning agent that helps soften skin, reduce transepidermal water loss, and improve the cushion of creams, balms, and oil-based products.
What does Phytosteryl Oleate do in a cosmetic formula?
This ingredient is a lipid emollient and skin-conditioning agent that helps soften skin, reduce transepidermal water loss, and improve the cushion of creams, balms, and oil-based products.
Is Phytosteryl Oleate clean?
It is generally well tolerated, with low irritation potential and little clean-standard friction. Sensitivity is uncommon, though final product performance depends on purity and the quality of the vegetable feedstocks used.
Is Phytosteryl Oleate sustainable?
This material is typically sourced from vegetable oil or forestry-derived lipid streams, so its footprint depends on the crop, traceability, and any palm-linked inputs. It is expected to be biodegradable and is not known for environmental persistence concerns.
Is Phytosteryl Oleate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic frameworks when made from permitted renewable feedstocks using allowed esterification chemistry. From a Green Chemistry view, it aligns well through renewable sourcing, low volatility, and good biodegradability, with sourcing traceability as the main caveat.
How does Phytosteryl Oleate work chemically?
The molecule is a large lipophilic ester built from a steroid-like alcohol backbone and an 18-carbon monounsaturated fatty acid chain, which gives it strong oil-phase compatibility and a substantive skin feel. It is typically used in the oil phase of emulsions, balms, and anhydrous products at low single-digit percentages, and the unsaturated chain means antioxidant support can help protect formulas from rancidity over time.
