Glyceryl Triacetyl Hydroxystearate ●
TL;DR. This ingredient is primarily an oil-phase structurant and emollient, helping thicken oils, stabilize sticks and balms, and give formulas a smooth, cushioned feel.
What does Glyceryl Triacetyl Hydroxystearate do in a cosmetic formula?
This ingredient is primarily an oil-phase structurant and emollient, helping thicken oils, stabilize sticks and balms, and give formulas a smooth, cushioned feel.
Is Glyceryl Triacetyl Hydroxystearate clean?
It has a low irritation profile and is not a common clean-standard concern. The main review point is processing and feedstock documentation, rather than a specific restricted-list issue.
Is Glyceryl Triacetyl Hydroxystearate sustainable?
This material is commonly based on plant-derived fatty acids, often from castor, plus glycerin and acetyl groups from simple acid chemistry. It is expected to be biodegradable and has low persistence concern compared with silicone or fluorinated materials.
Is Glyceryl Triacetyl Hydroxystearate COSMOS-approved?
It is generally compatible with COSMOS-natural style formulation when made from approved feedstocks and allowed esterification or acetylation chemistry. From a Green Chemistry view, it aligns well when renewable fatty-acid inputs and efficient solvent-minimized processing are used.
How does Glyceryl Triacetyl Hydroxystearate work chemically?
The molecule is a glycerol-based ester built from a saturated C18 fatty-acid backbone with acetylated hydroxyl functionality, which gives it waxy structuring behavior in anhydrous systems. It is typically used in low single-digit percentages to build viscosity, improve pay-off, and reduce oil bleed, and it is more relevant to oil-phase stability than to formula pH.
