Additional information

m-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline was shown to degrade by a pseudo-first order behaviour. Half-life times at 25°C and pH 4, pH 7 and pH 9 were determined to be 4.0, 5.0 and 5.1 days, respectively. The test item is stable in water.

Regarding the biodegradation, no biodegration were observed in the inherent biodegradation (8 % biodegradation) and ready biodegradation (2 % biodegradation) test of m-(2,3 -epoxypropoxy)-N,N-bis(2,3 -epoxypropyl) aniline.

m-(2,3 -epoxypropoxy)-N,N-bis(2,3 -epoxypropyl) aniline is not biodgeradable in water.

The simulation test for the biodegradation in water and sediment was not performed in accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the simulation testing on ultimate degradation in surface water, and sediment simulation testing (required in section 9.2.1.2, and 9.2.1.4) do not need to be conducted based on the findings of the Chemical Safety Assessment; the substance does not fulfil classification criteria according to the applicable regulations and does not fulfil the criteria for vPvB or PBT.

The biodegradation in soil was waived in accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the soil simulation testing (required in section 9.2.1.3) does not need to be conducted as direct and indirect exposure of soil is unlikely.

In accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the simulation testing on ultimate degradation in surface water, and sediment simulation testing (required in section 9.2.1.2, and 9.2.1.4) do not need to be conducted based on the findings of the Chemical Safety Assessment; the substance does not fulfil classification criteria according to the applicable regulations and does not fulfil the criteria for vPvB or PBT.

The adsorption coefficient was found to be ,Log Koc = 1.93 at 20oC. The substance is slightly moblie (according to Guth mobility classification, 1985) and the substance is expected to have a low potential for bioaccumulation as it has a low octanol-water partition coefficient (Log Pow = 1.6)
