About M-PHENYLENEDIAMINE SULFATE
The sulfate salt of m-phenylenediamine. Same prohibition as the parent diamine — banned in EU cosmetics and clinically linked to hair-dye allergy.
Detailed Analysis
m-Phenylenediamine sulfate (CAS 541-70-8) is the sulfate salt of m-phenylenediamine and is covered by the same EU Cosmetics Regulation Annex II entry — the prohibition applies to the diamine and its salts. It is a recognised cross-reactor with PPD-class hair-dye allergens and carried the same in-vitro genotoxicity signals that led to the parent compound being removed from the permitted hair-dye list. There is no legitimate cosmetic use pathway.
