PENTAERYTHRITYL TETRAISOSTEARATE
PENTAERYTHRITYL TETRAISOSTEARATE is a long-chain lipid ester. Its structure has a pentaerythrityl core joined to four isostearic-acid groups, which helps explain its place in oil-phase formulas such as foundations, lip products, creams, and other products with a richer texture.
PENTAERYTHRITYL TETRAISOSTEARATE: what it is
PENTAERYTHRITYL TETRAISOSTEARATE is a long-chain lipid ester. Its structure has a pentaerythrityl core joined to four isostearic-acid groups, which helps explain its place in oil-phase formulas such as foundations, lip products, creams, and other products with a richer texture.
The word "tetraisostearate" is what distinguishes it from similarly named pentaerythrityl derivatives: the core is connected to four isostearate groups. It is not a whole plant oil or an extract, but a defined substance made by joining those chemical parts and used to shape a formula's feel and structure.
PENTAERYTHRITYL TETRAISOSTEARATE: what it does in cosmetics
As an emollient, PENTAERYTHRITYL TETRAISOSTEARATE can make the skin's surface feel softer and improve slip as a product is spread. In creamy or colour cosmetics, that can support a less dragging application and a more even feel, without making the ingredient a skin treatment.
It is also classified as an emulsifying and cleansing surfactant. In practical terms, an emulsifier helps water and oily components stay distributed in one preparation, while the cleansing function relates to removing oily material during use. The CIR assessment examined this tetraester with related compounds for cosmetic safety; it was not a clinical test of a visible cosmetic result.
