Description of key information
Additional information
Aquatic / sediment
Data are not required as the substance is registered under provision of Article 12(1)(c) of REACH.
As the log Kow of isovaleric acid is low (log Kow = 1.7, Sect. 4.7, OXEA, 2010) and the substance is readily biodegradable (Urano, 1986 and Dias 1971), the potential for bioaccumulation of isovaleric acid is low.
In addition, calculated Log BCF and log BAF (upper trophic) values of 0.5 and 0.748 respectively (US EPA EPI Suite v4.10, program component BCFBAF v3.01) indicate a low potential of isovaleric acid for bioaccumulation in aquatic organisms (GUBDH, 2012).
Terrestrial
No data available (data are not required as only Annex VII data requirments have to be fulfilled).
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.
