Description of key information
Additional information
Triboron trimethyl hexaoxide is known to rapidly hydrolyse in contact with water to form methanol (CAS 67-56-1) and boric acid (CAS 10043-35-3) (Steinberg and Hunter, 1957). For methanol relevant biodegradation data was gathered from the ECHA dissemination dossier (d.d. 2014 -04 -24). Methanol is qualified as readily biodegradable based on the results of a total of 4 key studies. For boric acid, the concept of biodegradation does not apply as it is an inorganic substance. For regulatory purposes, inorganic substances are to be regarded as not readily biodegradable. Therefore, the parent substance triboron trimethyl hexaoxide needs to be qualified as not readily biodegradable.
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.
