METHYL DI-T-BUTYL HYDROXYHYDROCINNAMATE.

Questionable CAS 6386-38-5 / ANTIOXIDANT, PERFUMING

Methyl Di-T-Butyl Hydroxyhydrocinnamate primarily functions as an antioxidant within cosmetic formulations, safeguarding other ingredients from oxidation and degradation. Its role is to enhance product stability and maintain aesthetic integrity, rather than offering direct benefits to the skin.

Summary

Antioxidant Perfuming

Science

Mechanism of Action

This compound acts as an antioxidant by inhibiting oxygen-promoted reactions, which are a primary cause of ingredient deterioration and unwanted changes in cosmetic products. By neutralizing these oxidative processes, it helps to preserve the integrity and longevity of the formulation.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a dedicated safety assessment for Methyl Di-T-Butyl Hydroxyhydrocinnamate, although it is reported as an impurity in Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, which the CIR deemed safe up to 0.8%. PubChem lists GHS classifications indicating it may be 'Harmful if swallowed' and 'Toxic to aquatic life with long lasting effects'. EWG also raises concerns regarding its potential for high persistence and bioaccumulation, low-moderate non-reproductive organ system toxicity, and low ecotoxicology.

Verdict

Questionable

While serving a valuable role in product stability, the absence of a dedicated safety review by CIR and noted environmental and health concerns render Methyl Di-T-Butyl Hydroxyhydrocinnamate a questionable ingredient for precision skincare.
