Description of key information
Additional information
Sodium isobutyrate solution ( Reaction mass of lithium 3-hydroxy-2,2,4-trimethylpentanoate and lithium isobutyrate and sodium 3-hydroxy-2,2,4-trimethylpentanoate and sodium isobutyrate) was shown to be readily biodegradable in a 28 -day OECD 301A DOC die-away test. Hence, it can be expected that the substance will degrade rapidly in the environment.
As the substance was found to be readily biodegradable no further testing on biodegradability or hydrolysis were considered necessary.
As the substance has an extremely low log Kow, testing for adsorption/desorption is not required according to REACH Annex VIII Column 2.In addition to this, the low log Kow of the substance means that testing for bioaccumulation is not necessary according to REACH Annex IX Column 2.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
