Interesting Fact: P-Methylaminophenol Sulfate

Two of the most dangerous chemicals found in generic hair dyes are resorcinol, and toluene-2,5-diamine sulphate (TDS; 2,3). Both of these rated a high 8 according to EWG’s Skin Deep cosmetics database, but it’s very important to note why. Resorcinol has been placed on the UN’s list of endocrine disruptors, and TDS is even potentially carcinogenic.
