Abstract

The Expert Panel for Cosmetic Ingredient Safety (Panel) reviewed the safety of 1-Hydroxyethyl 4,5-Diamino Pyrazole Sulfate, which functions as an oxidative hair dye ingredient. The Panel reviewed relevant data provided in this safety assessment, and concluded that 1-Hydroxyethyl 4,5-Diamino Pyrazole Sulfate is safe in the present practices of use and concentration in oxidative hair dye formulations.
