Additional information

Based on REACH guidance, the study does not need to be conducted because the test substance is inorganic. However, sodium borohydride rapidly hydrolyzes in water to form sodium borate/boric acid and hydrogen gas with a half-lives ranging from seconds to minutes at environmentally relevant pHs. The log partition coefficient n-octanol/water (Log Pow) of boric acid was reported to be -1.09 ± 0.16 (22 ± 1 ºC), pH 7.5.
