- Executive summary:
A laboratory study for assessment of the Ready Biodegradability of the test substance was performed, i.e. the CO2 Evolution Test according to OECD Guideline 301 B. A positive control (reference substance benzoic acid, sodium salt) and 2 negative controls were included in the test program. The validity criteria of the test guideline were met.
According to the test results the test item had to be assessed to be not readily biodegradable.
