Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

A hydrolysis study cannot be performed with this substance, as the water solubility of the substance is lower than 1 mg/l.

High levels (55%) of biodegradation were observed in OECD 301B test despite the low water solubility of Radia 7853.The data do demonstrate that Radia 7853 is ultimately biodegradable. The observed level of 55% biodegradation after 28 days implies that Radia 7853 is completely mineralized to CO2(with remainder incorporated into cellular material). Levels of >50% mineralization are typical for complete mineralization of substances with low water solubility.The 28-day period can be extended, especially relevant for substances with low water solubility. The test (OECD301B) with Radia 7853 was terminated after 28 days. Extrapolation of the curve indicates that the 60% level would have been reached after 30-32 days. It is therefore concluded that Radia 7853 should be considered as readily biodegradable.

The adsorption study shows log Koc values > 5.63 for all constituents of the substance. This shows that the substance is not mobile in soil.
