In the model N-(1,4-dimethylpentyl)-N'-phenylbenzene-1,4-diamine is treated as a type 1 chemical, i.e. the chemical partitions into all environmental media. Estimation is carried at an environmental temperature of 25 °C.

Applicant's summary and conclusion

Executive summary:

The distribution of N-(1,4-dimethylpentyl)-N'-phenylbenzene-1,4-diamine in the envitonment was calculated according to the Mackay fugacity model level I (Currenta,2010) based on the physico-chemical properties. The main target compartment for N-(1,4-dimethylpentyl)-N'-phenylbenzene-1,4-diamine is air with 0.17 %, followed by water with 4.06 %, soil with 47.43 % and sediment with 47.95 %.
