PHYTOSTEROL ESTERS ●
TL;DR. This ingredient is primarily an emollient and skin-conditioning lipid. It adds cushion, improves barrier feel, and can support richer textures in creams, balms, lip products, and anhydrous formulas.
What does PHYTOSTEROL ESTERS do in a cosmetic formula?
This ingredient is primarily an emollient and skin-conditioning lipid. It adds cushion, improves barrier feel, and can support richer textures in creams, balms, lip products, and anhydrous formulas.
Is PHYTOSTEROL ESTERS clean?
Clean-beauty frameworks generally treat this ingredient as low concern, with little restricted-list friction and low sensitization potential. The main quality checks are residual catalysts, residual solvents, and plant-oil impurity control from processing.
Is PHYTOSTEROL ESTERS sustainable?
This material is typically plant-derived, often from vegetable oils or plant-processing side streams. It is oil-soluble and expected to biodegrade through ester breakdown, with a stronger sustainability profile when feedstocks are traceable and not linked to high-pressure land use.
Is PHYTOSTEROL ESTERS COSMOS-approved?
It can be compatible with COSMOS-natural and COSMOS-organic frameworks when made from permitted natural feedstocks using allowed esterification chemistry. From a Green Chemistry lens, it fits best when renewable inputs, efficient processing, and minimal solvent use are documented.
How does PHYTOSTEROL ESTERS work chemically?
The molecule is a fatty acid ester of a plant sterol alcohol, combining a rigid sterol core with a long hydrophobic acyl chain. It is water-insoluble, used in the oil phase often around 0.1% to 5%, and its oxidation profile depends mainly on the attached fatty acids and the antioxidant system in the formula.
