Additional information

"There are no experimental studies on the toxicokinetics of ethoxylated and propoxylated diaminotoluene.The ethoxylated and propoxylated diaminotoluene is made fromo-diaminotoluene. Commercialo-toluenediamine is a mixture of 40% toluene-2,3-diamine and 60% 4-methyl-o-phenylenediamine. The toxicokinetics of propoxylated diaminotoluene is inferred from the read across from toluene-2,4-diamine and toluene-2,6-diamine to the toluene-2,3-diamine and 4-methyl-o-phenylene diamine and from propane-1,2-diol, oxydipropanol and [(methylethylene)bis(oxy)]-dipropanol. Diaminotoluene has two free amino groups, thus no longer polymer oligomers are likely to consist predominantly of chains of between one and two monomers."
