Pentaerythrityl Tetraisostearate ●
TL;DR. This ingredient is a rich emollient ester used to add cushion, gloss, and slip in lip products, color cosmetics, and creams. It also helps disperse pigments and bind powders into a smoother film.
What does Pentaerythrityl Tetraisostearate do in a cosmetic formula?
This ingredient is a rich emollient ester used to add cushion, gloss, and slip in lip products, color cosmetics, and creams. It also helps disperse pigments and bind powders into a smoother film.
Is Pentaerythrityl Tetraisostearate clean?
From a clean-beauty perspective, it is generally low in irritation potential and not a common allergen. The main scrutiny is origin and processing, since it is an industrially made ester and supplier documentation matters.
Is Pentaerythrityl Tetraisostearate sustainable?
This material is usually made from fatty-acid inputs combined with a synthetic polyol, so its footprint depends on the source of the fatty acids and manufacturing controls. It is an ester and is expected to biodegrade more readily than silicone oils, though its branched, high-molecular-weight structure can make breakdown slower than simpler plant oils.
Is Pentaerythrityl Tetraisostearate COSMOS-approved?
It can have partial COSMOS alignment when made from permitted feedstocks using allowed esterification chemistry, but it is not automatically a COSMOS-organic fit without documentation. From a Green Chemistry view, it scores better when renewable fatty acids are used and when manufacturing limits solvent and purification burdens.
How does Pentaerythrityl Tetraisostearate work chemically?
The molecule is a bulky, highly lipophilic tetraester built from a four-arm alcohol core and branched C18 fatty chains, which gives it high viscosity, strong pigment wetting, and a non-greasy cushion. It is typically stable across normal anhydrous and emulsion pH ranges, and its saturated, branched chains make it less prone to oxidation than many unsaturated oils.
