Description of key information


Ready biodegradability:

One study (TNO, 2000), scored as Klimisch 1 and selected as a key study, was performed according to the OECD guideline 301B.

After 28 days, the test substance Rhodixan A-1 was biodegraded for 19.4% at test substance concentrations of 25 mg/l and 14.9% at 50 mg/l. Rhodixan A-1 therefore did not pass the criteria given in the guideline (i.e. > 60% degradation reached within a 10 day period counting from the day that the level of degradation exceeded 10% ), and is therefore assessed to be not readily biodegradable in this test.
