Triolein ●
TL;DR. This ingredient functions mainly as an emollient and skin-conditioning lipid, helping soften skin, reduce transepidermal water loss, and improve slip in creams, oils, balms, and makeup.
What does Triolein do in a cosmetic formula?
This ingredient functions mainly as an emollient and skin-conditioning lipid, helping soften skin, reduce transepidermal water loss, and improve slip in creams, oils, balms, and makeup.
Is Triolein clean?
From a clean-beauty perspective, it is generally well tolerated and not a common restricted-list concern. Sensitivity issues are uncommon, though rancid or poorly stabilized lipid materials can affect odor and skin feel.
Is Triolein sustainable?
This material can be sourced from vegetable oils or made from renewable fatty-acid and glycerin feedstocks. It is expected to be biodegradable, with the main sustainability variables coming from agricultural sourcing, traceability, and refining practices.
Is Triolein COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic when derived from approved natural feedstocks and processed through allowed methods. It fits Green Chemistry principles well through renewable sourcing, biodegradability, and relatively simple lipid processing.
How does Triolein work chemically?
The molecule is a neutral triacylglycerol with three monounsaturated C18 fatty chains esterified to a glycerol backbone, which gives it high lipophilicity and a liquid-oil sensory profile. In formulation, it belongs in the oil phase, is stable across typical cosmetic pH ranges, and benefits from antioxidant support because unsaturated lipids can oxidize over time.
