TRIPHENYLPHOSPHINE.

Avoid CAS 603-35-0 / NAIL CONDITIONING

Triphenylphosphine is an organophosphorus compound primarily recognized in industrial chemistry as a ligand for catalysts, enhancing reaction rates and yields. While there are limited historical mentions of its use in cosmetic applications such as nail conditioning or fragrances, current research indicates no specific mechanism of action or benefits for skin.

Science

No known mechanism of action for cosmetic benefits on skin has been identified for Triphenylphosphine. Its primary chemical roles involve forming stable metal complexes and acting as a Lewis base catalyst or reducing agent in various organic reactions.

Safety

CIR Status
Not reviewed
Sensitization risk High

Official safety assessments for Triphenylphosphine specifically as a skincare ingredient by bodies such as CIR, SCCS, or FDA are currently unavailable; existing CIR reports often pertain to a distinct compound, Triphenyl Phosphate. Classified as a hazardous industrial chemical, it is known to cause irritation to the respiratory tract, eyes, and skin. Chronic or high-level exposure is associated with potential damage to the liver, kidneys, and nervous system.

Our Assessment

Avoid

Given its classification as a hazardous industrial chemical, demonstrated high irritancy, lack of established cosmetic benefits for skin, and unreviewed safety status, Triphenylphosphine is not recommended for skincare formulations.
