Description of key information
Physical appearance (BHMT-H): Solid but manufactured as an aqueous solution (liquid)
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- liquid
- Form:
- solid - liquid: aqueous solution
Additional information
The anhydrous form of the substance is a solid under ambient conditions, but it is typically manufactured in situ as an aqueous solution (liquid). Thus, the substance is not marketed or used in the solid form.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
