Acid Orange 7 showed to be ready biodegradable under standardised test conditions in OECD301C (MITI TEST) since the level of biodegradability is > 60%. No test on adsorption/desorption properties was performed considering the negative logKow and the expected low potential of adsorption.

Based on the results of the tests, Acid Orange 7 is considered to be ready biodegradable but not hydrolisable and is expected to show low adsorption potential on soil.
