Isostearyl Linoleate ●
TL;DR. This ingredient functions mainly as an emollient and skin-conditioning ester, adding slip, softness, and a lightweight oily feel to creams, lotions, balms, and color cosmetics.
What does Isostearyl Linoleate do in a cosmetic formula?
This ingredient functions mainly as an emollient and skin-conditioning ester, adding slip, softness, and a lightweight oily feel to creams, lotions, balms, and color cosmetics.
Is Isostearyl Linoleate clean?
It is generally viewed as low-concern in clean-beauty screening, with low irritation potential and no common restricted-list issues. The main review points are feedstock origin and the quality controls used to manage residual reactants or oxidation byproducts.
Is Isostearyl Linoleate sustainable?
This material is typically based on fatty raw materials that may be plant-derived, though supplier documentation is needed to confirm origin. It is expected to be biodegradable as a long-chain ester, but sourcing can vary, including possible palm-linked or mixed oleochemical supply chains.
Is Isostearyl Linoleate COSMOS-approved?
It can align with COSMOS-natural when made from approved natural-origin fatty inputs using permitted esterification chemistry, but eligibility depends on supplier documentation. From a Green Chemistry view, it is a reasonable fit when renewable feedstocks, low residual solvents, and good biodegradability data are demonstrated.
How does Isostearyl Linoleate work chemically?
The molecule is a long-chain branched fatty ester made from a C18 branched alcohol and a C18 polyunsaturated fatty acid, which gives it spreadability and a cushioned emollient profile. Because the fatty acid portion is unsaturated, formulas may need antioxidant support and sensible packaging to limit oxidation over shelf life.
