Description of key information


The biodegradation of Ethyl isovalerate was determined in a reliable study according to OECD 301 D and in compliance with GLP. No inhibitory effects on microorganisms were observed up to 3 mg/L. According to OECD criteria, the test substance is readily biodegradable.

Henry´s Law constant:

Evaporation into the air is considered to be low based on a calculated Henry´s Law Constant value of 76.9 Pa m3/mol derived with the formula in ECHA Guidance R.16.

Hydrolysis and adsorption:

Ethyl isovalerate is readily biodegradable and further has a log Kow value below 3 (log Kow = 2.47). Both values indicate that the adsorption to organic sediments and soil particles is low. Furthermore, the abiotic degradation (hydrolysis) of the substance is not considered to be a relevant degradation pathway in the environment.
