Toxic substances list: MAPBAP acetate

The substance Methylium, [4-(dimethylamino)phenyl]bis[4-(ethylamino)-3-
methylphenyl]-, acetate, Chemical Abstracts Service Registry Number (CAS RN) 72102-55-7, is commonly known as “MAPBAP acetate”.

MAPBAP acetate is used in Canada as a dye mainly in the production of certain paper products made from mechanical grade pulp such as newsprint.

The risk assessment concluded that the use of MAPBAP acetate may have an immediate or long-term harmful effect on the environment but may not constitute a danger to human life or health.

Therefore, Environment Canada manages the environmental risk with Guidelines that set standards on MAPBAP acetate retention, performance of the effluent treatment system and containment measures for the pulp and paper sector.

Health Canada will manage potential health risk that could arise from any new use of MAPBAP acetate through the Significant New Activity provisions. For more information, please visit the Chemical Substances Website.
