Pentaerythrityl Tetra-Di-T-Butyl Hydroxydrocinnamate ●
TL;DR. This ingredient is a synthetic antioxidant used to slow oxidation in oils, waxes, fragrances, pigments, and packaging-adjacent raw materials. In formulas, it helps protect color, odor, and texture from rancidity or oxidative drift.
What does Pentaerythrityl Tetra-Di-T-Butyl Hydroxydrocinnamate do in a cosmetic formula?
This ingredient is a synthetic antioxidant used to slow oxidation in oils, waxes, fragrances, pigments, and packaging-adjacent raw materials. In formulas, it helps protect color, odor, and texture from rancidity or oxidative drift.
Is Pentaerythrityl Tetra-Di-T-Butyl Hydroxydrocinnamate clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic phenolic stabilizer with limited skin-benefit rationale and data-gap concerns in consumer-facing ingredient standards. It is not a common irritant at cosmetic use levels, but its restricted-list standing depends on the standard being applied.
Is Pentaerythrityl Tetra-Di-T-Butyl Hydroxydrocinnamate sustainable?
This material is typically made from petrochemical feedstocks and is designed to resist oxidation, which also makes its environmental profile less favorable. It is highly hydrophobic, poorly water-soluble, and not a strong fit for readily biodegradable ingredient design.
Is Pentaerythrityl Tetra-Di-T-Butyl Hydroxydrocinnamate COSMOS-approved?
This ingredient is not aligned with COSMOS natural or organic ingredient principles and is generally not treated as permitted for certified natural formulas. Its Green Chemistry fit is weak because it relies on nonrenewable feedstocks, has low biodegradability, and functions through chemical persistence rather than easy environmental breakdown.
How does Pentaerythrityl Tetra-Di-T-Butyl Hydroxydrocinnamate work chemically?
The molecule is a bulky, high-molecular-weight hindered phenolic antioxidant that donates hydrogen to interrupt free-radical oxidation chains in lipids and polymer-adjacent materials. It is oil-dispersible rather than water-soluble, used at very low stabilization levels, and is generally chosen for heat and oxidation stability rather than direct skin activity.
