Is isobutanol toxic?
There is a preponderance of evidence of public information on the biodegradation and toxicology on Isobutanol. In a robust summary report by a panel of toxicologists from the SIDS OECD assessment on Isobutanol, many of the studies referenced state that isobutanol is readily biodegradable and the main environmental conclusion from the report is that Isobutanol is currently of low priority for further work due to its low hazard profile. In another report from IPCS (International Programme on Chemical Safety) that was sponsored by the World Health Organization (WHO) states that Isobutanol is readily biodegradable and it is degraded in significant amount within a few hours, and degradation would be expected to be complete within a few days and thus isobutanol does not bioaccummulate. Isobutanol also occurs naturally in a variety of fruits (e.g., cherry, grape, apple, raspberry) and is added to foods and beverages as a flavouring agent (e.g., butter, cola, fruit, liquor, rum and whiskey) (W
