Conclusion on classification

TMBX is hydrolytically unstable and hydrolyses to form methanol and boric acid, both of which are toxicologically significant species. TMBX is readily biodegradable into the relevant components and is not classified for the environment. In addition Boric acid and Methanol are not classified for the environment.
