Tetrahydroxystearate/Tetraisostearate ●
TL;DR. This ingredient is an oil-phase emollient and structuring agent that adds cushion, gloss, and slip while helping stabilize pigments and anhydrous sticks or balms.
What does Tetrahydroxystearate/Tetraisostearate do in a cosmetic formula?
This ingredient is an oil-phase emollient and structuring agent that adds cushion, gloss, and slip while helping stabilize pigments and anhydrous sticks or balms.
Is Tetrahydroxystearate/Tetraisostearate clean?
It is generally viewed as low-irritation and is not a common allergen or restricted-list focus in clean beauty standards. The main review point is documentation of feedstock origin and residual processing impurities rather than routine skin-safety concern.
Is Tetrahydroxystearate/Tetraisostearate sustainable?
This material is typically based on fatty-acid chemistry that can be plant-derived, although supply chains may vary by manufacturer. It is expected to be biodegradable by ester breakdown, but large-scale sourcing can carry palm, castor, or other crop-traceability considerations.
Is Tetrahydroxystearate/Tetraisostearate COSMOS-approved?
It can fit COSMOS-natural when the feedstocks and esterification process meet the standard’s allowed inputs and processing rules, but supplier certification is needed. From a Green Chemistry view, it scores better when made from renewable fatty acids and simple ester chemistry, with less alignment if feedstocks are petrochemical or poorly traceable.
How does Tetrahydroxystearate/Tetraisostearate work chemically?
This compound is a high-molecular-weight, branched polyol ester with multiple long-chain fatty groups, which explains its rich slip, film formation, and viscosity-building behavior in oils. It is used mainly in anhydrous or emulsion oil phases, is broadly pH-insensitive, and is more oxidatively stable than many unsaturated plant oils because it contains esterified, saturated or branched fatty chains.
