TRIPHENYL PHOSPHATE.

Questionable CAS 115-86-6 / PLASTICISER

Triphenyl Phosphate is a functional ingredient primarily utilized as a plasticizer in cosmetic formulations. Its role is to enhance film flexibility and durability, improving product adhesion and structural integrity. Upon cutaneous exposure, it undergoes metabolism to diphenyl phosphate.

Summary

plasticizer

Science

Mechanism of Action

As a plasticizer, Triphenyl Phosphate improves the physical integrity and longevity of cosmetic films by increasing their flexibility and adherence to surfaces. This action contributes to enhanced product performance and wear. When in contact with biological tissues, it is metabolized into diphenyl phosphate.

Key findings

  1. 01 Human studies using nail products with concentrations up to 7% Triphenyl Phosphate did not induce irritation or sensitization.
  2. 02 An in-use safety evaluation of a nail polish containing 1.0041% Triphenyl Phosphate reported no adverse events.

Dusting Analysis

Not commonly dusted

Triphenyl Phosphate's established role is primarily as a plasticizer in specific cosmetic applications, particularly nail products. The available research does not indicate that this ingredient is commonly overhyped or 'dusted' in general skincare contexts.

Triphenyl Phosphate presents as a colorless, crystalline powder with a melting point of approximately 49-50 °C. No specific optimal pH range for stability in cosmetic formulations has been identified in the provided data.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
14.5%
Sensitization risk Moderate

The CIR Expert Panel concludes Triphenyl Phosphate is safe in cosmetics, supporting usage up to 14.5% in polish strips, up to 11.9% in nail enamels, and up to 1% in nail lotions. This assessment highlights very low skin absorption and negative genotoxicity studies, with FDA approval as an indirect food additive. However, the SCCS has expressed concerns regarding a possible genotoxic potential, stating that its safety cannot be conclusively confirmed based on current evidence. While human patch tests in nail products showed low irritation and sensitization potential at concentrations up to 7%, isolated case reports of allergic contact dermatitis have been documented in individuals exposed to various plastic products containing Triphenyl Phosphate.

Our Assessment

Verdict

Questionable

Primarily serving as a plasticizer for nail product integrity, Triphenyl Phosphate lacks direct clinical efficacy data for skin benefits, and ongoing regulatory concerns regarding its genotoxic potential suggest a cautious approach for precision skincare formulations.
