Description of key information
Additional information
Hydrolysis studies show that isobutyric anhydride added to water rapidly converts to isobutyric acid. Thererfore, isobutyric acid data is being used by read across for most environmental fate and ecotox endpoints.
Biodegradation in water: screening tests
Isobutyric acid has been shown to be readily biodegradable as combined evidence from two biodegradation tests
1. - test similar to OECD TG 302 B (Hoechst AG, undated; RL2; KS)
2. - test similar to OECD TG 301 E (Henkel KGaA, 1983; RL3; WoE)
Biodegradation in water and sediment: simulation tests
Tests need not be conducted, as isobutyric acid is readily biodegradable.
Biodegradation in soil
Tests need not be conducted, as isobutyric acid is readily biodegradable.
Mode of degradation in actual use
Data for mode of degradation in actual use are not required under REACH.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
