PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE.

Valuable CAS 6683-19-8 / ANTIOXIDANT

Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate is a high-performance antioxidant, primarily integrated into skincare formulations to safeguard the product itself from oxidative degradation. This action extends the shelf life and maintains the integrity and efficacy of other active ingredients within the formula, while also offering surface-level antioxidant protection to the skin.

Summary

Antioxidant

Science

Mechanism of Action

This compound functions by neutralizing oxidative stress induced by environmental aggressors such as UV radiation and atmospheric pollution. Its high molecular weight restricts significant epidermal penetration, directing its antioxidant action primarily to the skin's surface. By preserving the stability of other components, it indirectly supports the skin's hydration and defense mechanisms against environmental stressors.
