Triphenyl Phosphate
What is Triphenyl Phosphate?
Triphenyl phosphate (TPP) is an organophosphate ester compound, synthetically produced from phosphorus oxychloride and phenol. It serves primarily as a plasticizer and film former in cosmetic formulations, especially in nail coatings and hair styling products. In these applications, TPP integrates into polymer matrices to increase flexibility, reduce brittleness, and prevent cracking during wear or application. This functionality allows for smoother spreading and longer-lasting finishes on nails or hair. Originating from industrial chemistry, it replaces phthalates in some formulations due to similar plasticizing properties. Authoritative reviews, including those from cosmetic safety panels, note its use at low concentrations in rinse-off and leave-on products, where it modifies the mechanical properties of films without altering color or scent significantly. Its chemical stability contributes to product shelf life under varying conditions.
