T-BUTYL BENZOYL PEROXIDE.

Avoid CAS 614-45-9 / UV ABSORBER

T-Butyl Benzoyl Peroxide (TBPB) is an organic peroxide primarily employed as a radical initiator in industrial applications, such as polymerization and cross-linking processes. Current dermatological literature does not identify a recognized mechanism of action or direct skin benefits for TBPB in cosmetic formulations.

Summary

Science

Mechanism of Action

Our research indicates no widely established mechanism by which T-Butyl Benzoyl Peroxide confers active dermatological benefits when applied topically to the skin. Its known function pertains to industrial chemical reactions as a radical initiator.

Dusting Analysis

Not commonly dusted

T-Butyl Benzoyl Peroxide lacks recognized benefits for topical skin application and is primarily an industrial compound; therefore, it is not considered an ingredient prone to 'dusting' or exaggerated marketing claims in precision skincare.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

T-Butyl Benzoyl Peroxide is classified by Safety Data Sheets as causing skin irritation (Category 2) and possessing a high potential for allergic skin reactions (Category 1). It is also harmful if inhaled (Category 4). There is a documented concern that its use in polymers, including those for food or cosmetics, may lead to the formation of benzene upon decomposition. While Benzoyl Peroxide (BPO) has specific SCCS recommendations against its use due to potential tumor promotion, these findings are distinct and not directly applicable to T-Butyl Benzoyl Peroxide. No specific FDA status for TBPB related to skin benefits has been identified.

Our Assessment

Verdict

Avoid

Due to a complete absence of documented skin benefits, coupled with classified risks of skin irritation, allergic reaction, and potential for toxic decomposition products, T-Butyl Benzoyl Peroxide is not suitable for topical cosmetic applications.
