Canada permits manufacture and import of amides with restrictions

Canada's environment department has approved, with restrictions, the manufacture or import of the substance amides, tall-oil fatty, N-[3-(dimethylamino)propyl], effective from 25 September.

The restrictions applied include strict terms of disposal because the substance is suspected of being toxic, or capable of becoming so, according to section 64 of the Canadian Environmental Protection Act (Cepa).

In addition to record-keeping, the notifier must also:

only import the substance to incorporate it as a component of asphalt or bitumen emulsions, and transfer physical control only to those who will use it in that way;
write to the environment minister at least 120 days before manufacturing, giving any information required by law, supplying the address of the Canadian facility producing it, describing the manufacturing process, providing a flow diagram and outline of the major steps in the process; and
provide written information about the terms and ministerial condition to any recipient in control of the substance, waste, containers or transportation vessels. They must also get confirmation that the information was received.

Echa's database lists the substance as very toxic to aquatic life and causing severe skin burns and eye damage.
