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

A biodegradation study (Mitsubishi Kasei Institute of Toxicological and Environmental Sciences, 1988) was conducted to assess the ready biodegradability of ETD in water. The study was conducted according to official test methods (Test Method Relating to New Chemical Substances, Kanpogyo No. 5, Yakuhatsu No. 615, 49 Kikyoku No. 392, 1974) and in compliance with GLP.

On the basis of oxygen consumption, the test material was found not to have degraded over the 28 -day monitoring period (mean degradation -1%). On this basis, ETD is considered not to be readily biodegradable. It was noted that residual test material concentrations in media had decreased over the monitoring period, however this was considered to have been due to volatilization.
