Additional information

Based on the resutls of the published report where the biodegradability of typycal leather chemicals are degraded by activated sludge treatment, analogue substance 1 showed a good biodegradability rate, without inhibilition of the respiration rate at any dose up to 1500 mg/l over 5 days.

As a supporting study also the test on FLL sample 9 was considered that estimates no effects on the respiration of Psuedomonas putida at loading rates up to 10,000 mg/l (4900 mg/l active substance) (WAF testing approach taken). This result indicates a substance with low aquatic toxicity.

Based on the read across considerations same results apply to target substance
