Description of key information
Zinc borates are ‘sparingly soluble salts,’ particularly the anhydrous form. Hydrolysis under dilute conditions leads to zinc hydroxide (via zinc oxide) and boric acid. Zinc hydroxide solubility is extremely low under neutral and basic conditions, leading to a situation where zinc borate hydrolyzes to zinc hydroxide and boric acid more quickly than it solubilizes. Under physiological conditions and typical environmental concentrations with neutral and lower pH, zinc borate can be considered to hydrolyze to zinc hydroxide and boric acid.
Key value for chemical safety assessment
Additional information
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.
