PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE
Is PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE safe for seborrheic dermatitis?
There is not enough ingredient-specific evidence to give Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate a confident seborrheic-dermatitis verdict. It is used to protect a formula from oxidation, not to treat the skin or scalp.
No applicable evidence found for this page shows that this antioxidant feeds Malassezia or improves seb derm. It is usually present at a low formula-support level, so the surrounding oils, fragrance, cleansers and actives matter more. Stop if the finished product repeatedly irritates affected skin.
