Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to Regulation (EC) No. 1907/2006, Annex IX, section, column 2, soil simulation testing need not be conducted if the substance is readily biodegradable and direct and indirect exposure of soil is unlikely.  A Ready Biodegradability test shows 54.1 % degradation after 28 days.  Although this does not fulfill the minimum criteria set out by the OECD method, it does however indicate that the material achieved >50 % within 30 days, highlighting its propensity for biodegradation. An inherent biodegradability test shows 80.5% degradation after 28 days, therefore the material is inherently biodegradable and as such not persistent in environmentally significant conditions.  Furthermore, given the use pattern of the substance direct or indirect exposure of soil is unlikely. Therefore, given the potential for biodegradation and the use patterns, further testing is scientifically unjustified.
