Description of key information

Simulation testing on ultimate degradation in surface water or sediment simulation testing is not required due to the predicted ready biodegradability of the substance and the low potential for adsorption to sediment.

Key value for chemical safety assessment

Additional information

Isobutyl-R-lactate is predicted to be readily biodegradable. According to Annex IX, column 2, of Regulation (EC) No 1907/2006 a study on "simulation testing on ultimate degradation in surface water or sediment simulation testing" does not have to be conducted if "the substance is readily biodegradable". Furthermore, it is concluded that the test item does not have a high potential for adsorption to sediment. According to Annex IX columns 1 and 2 of the Regulation (EC) No 1907/2006, sediment simulation testing is therefore not required.
