Environmental mutagenesis, 2(2), 111-124 (1980-01-01)
The mutagenic effects of 2,4-dinitrotoluene (2,4-DNT), purified and technical grades, 3,5-DNT, 2,4-diaminotoluene (2,4-DAT), and 2,5-DAT were tested in mice using one or more of the following: the dominant lethal assay, the sperm morphology test and/or the recessive spot test. Compounds

Postgraduate medical journal, 61(721), 1003-1005 (1985-11-01)
We describe two female patients aged 31 and 62 y who developed severe aplastic anaemia following the use of hair dye containing para-toluenediamine. One received a bone marrow transplant but died after developing graft versus host disease and severe opportunistic
Andrew Scheman et al.
Dermatitis : contact, atopic, occupational, drug, 22(4), 189-192 (2011-07-26)
Finding alternative hair dyes for individuals allergic to para-phenylenediamine (PPD) has been difficult. Newer permanent and demipermanent hair dyes that have replaced PPD with para-toluenediamine sulfate (PTDS) are now available. We examined whether individuals allergic to PPD will tolerate PPD-free
David A Basketter et al.
Cutaneous and ocular toxicology, 28(3), 104-106 (2009-06-26)
p-Phenylenediamine (PPD) is an important hair dye allergen, but there remains a reasonable suspicion that other hair dye chemicals may also be responsible for a proportion of the clinical burden of hair dye allergy. To assess to what extent presently
