Additional information

Diaminotoluene, propoxylated, 1-5.5 mol propoxylated is a relatively non-volatile liquid at room temperature (vapour pressure 3.05 x 10-3 hPa). The commercial material is fairly soluble in water (21 g/L) and has log P 0.3-2.8. There are no experimental studies on the toxicokinetics of propoxylated diaminotoluene. The toxicokinetics of propoxylated diaminotoluene are inferred from the read across from toluene-2,4-diamine and toluene-2,6-diamine to toluene-2,3-diamine and 4-methyl-o-phenylenediamine, and toluene-2,6-diamine, and propane-1,2-diol, oxydipropanol and [(methylethylene)bis(oxy)]dipropanol. Diaminotoluene has two free amino groups, thus the NLP polyols are likely to consist predominantly of chains of one or two monomers.

Discussion on bioaccumulation potential result:

There are no toxicokinetic data for propoxylated diaminotoluene. The propoxylated diaminotoluene is made from o-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.
