Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Abiotic degradation: Hydrolysis as a function of pH was determined according to OECD TG 111. This study showed that the substance is stable in acidic or neutral solutions (half life > 1 year at pH 4 and 7) but hydrolyses significantly in basic conditions (half life: 7.8 days at pH 9). However, degradation products are the corresponding acid and alcohol which are not classified for the environment in the Annex I of directive 67/548/EEC.

 

Biodegradation: The high trans quality (cis/trans: 10/90) is readily biodegradable according to OECD TG 301 F (Manometric Respirometry Test ) performed in GLP conditions. 89 % of biodegradation was measured after 28 days in the test conditions were all validity criteria were fulfilled. The biodegradation rate reached after the 10-day window (days 6 to 16) was 82 %, which exceeds the pass level of 60 %. Furthermore, biodegradation curves obtained with the reference substance Aniline alone and with the test material + Aniline showed no toxic effect of the test material on the microorganisms at the test concentration (100 mg/l).

This study clearly shows that the test material is fully degraded in the environment and does not induce long-term adverse effect on biota (non persistent material).

Bioaccumulation potential: The octanol-water partition coefficient of the substance was measured by the shake flask method following OECD 107, resulting in a Log Kow of 2.93. The substance is believed to have low potential for bioaccumulation.

Transport and distribution of the substance in the environment: According to the level III fugacity model from EPISUITE v4.00, the substance would be distributed between the four environmental compartments, air (0.497%), water (22.2%), soil (77.1%) and sediment (0.173%) with half-lives of 12 hours (air), 360 hours (water), 720 hours (soil) and 3240 hours (sediment).
