Triphenyl Phosphate (or TPP) (CAS No.204-112-2, EC No.115-86-6) is used to soften or make supple various synthetic polymers, including in nail polishes, enamels, or manicuring preparations.
It is not currently regulated under the Cosmetics Regulation (EC) No.1223/2009.

Benzophenone-4, Benzophenone-1, Triphenyl Phosphate: requests for Opinions to the SCCS, CosmeticOBS, 24 April 2023


1. In light of the data provided and taking under consideration the concerns related to potential endocrine disrupting properties of Triphenyl Phosphate, does the SCCS consider Triphenyl Phosphate safe when used as a plasticiser in nail products up to a maximum concentration of 5%?

Based on the currently available information, it is not possible for the SCCS to conclude on the safety of Triphenyl Phosphate because the genotoxicity potential cannot be excluded.

2. Alternatively, what is according to the SCCS the maximum concentration considered safe for use of Triphenyl Phosphate in nail products?


3. Does the SCCS have any further scientific concerns with regard to the use of Triphenyl Phosphate in nail products?

The SCCS mandates do not address environmental aspects. Therefore, this assessment did not cover the safety of Triphenyl Phosphate for the environment.
