PHENYL T-BUTYLNITRONE.

Valuable CAS 3376-24-7 / ANTIOXIDANT

Phenyl T-Butylnitrone (PBN) is a unique 'spin trap' antioxidant that precisely neutralizes destructive free radicals, converting them into stable, harmless molecules. It provides superior protection for vital cellular components like mitochondria and DNA, while also contributing significant anti-inflammatory benefits to the skin.

Science

Mechanism of Action

Phenyl T-Butylnitrone (PBN) operates via a 'spin trap' mechanism, actively targeting and sequestering aggressive free radicals such as hydroxyl and superoxide radicals. This process converts these destructive species into stable, non-reactive molecules, which are then either naturally cleared or reutilized within cellular pathways. PBN's action extends to providing superior protection for both mitochondrial function and DNA integrity. Additionally, it exerts an anti-inflammatory effect by inhibiting the expression of various pro-inflammatory genes, supporting a calmer, more resilient complexion.

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) has not conducted a specific review for Phenyl T-Butylnitrone. While other Phenyl-substituted compounds like 'Phenyl Trimethicone' have been deemed safe, this assessment does not directly apply to PBN. Independent safety evaluations by organizations like EWG Skin Deep assign PBN (Spin Trap) a 'LOW' concern rating for potential cancer, allergies, immunotoxicity, and developmental/reproductive toxicity.
