PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE
PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE is a manufactured organic antioxidant, also known as Antioxidant 1010. Its structure combines four phenolic portions with a pentaerythritol core through propionate groups; the phenolic groups are the part of the molecule that can interrupt oxidation reactions. It is not a plant oil or botanical extract, despite its long chemical-sounding name.

PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE: what it is
PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE is a manufactured organic antioxidant, also known as Antioxidant 1010. Its structure combines four phenolic portions with a pentaerythritol core through propionate groups; the phenolic groups are the part of the molecule that can interrupt oxidation reactions. It is not a plant oil or botanical extract, despite its long chemical-sounding name.
It is a large, low-volatility molecule designed to remain in the oil phase or other parts of a formula that need stability. It should not be confused with antioxidants added for a direct skin effect: its main relevance is the chemical behavior of the product itself over its shelf life, rather than a promise to treat the skin.
PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE: what it does in cosmetics
In cosmetics, PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE helps slow the oxidation of vulnerable formula components. In practical terms, this can help an oil-based base or a fragrance retain its odor, color, and texture more consistently while the product is stored and used. It supports the stability of the preparation; it is not an active intended to moisturize, brighten, or correct the skin.
A published safety assessment described cosmetic uses up to 0.8% and a repeated patch test at 0.5%. Those figures belong to the conditions examined and do not predict individual tolerance or the performance of every finished product. For someone reading a label, the reasonable expectation is a component that helps preserve the formula against oxidation, not an isolated clinical benefit for the skin.
