Description of key information
Biodegradation data were available for 1 stream within this Category. All data showed the test substances to be not readily biodegradable. Biodegradation rate was 7.3 % in 28 days for 68921-67-5. However, of the 240 measured constituents (at equal or above 0.1% w/w), and according to the criteria set out in the ECHA R.7b Information Requirements Guidance, 218 (BIOWIN 2), 204 (BIOWIN 3), 88 (BIOWIN 5) and 166 (BIOWIN 6) were predicted to be readily biodegradable based on the different models, with 218 constituents having at least one prediction of a high probability that it will biodegrade fast.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
