Ottawa, Ontario – A draft screening assessment from Health Canada has concluded that isophorone diisocyanate (IPDI), used in some polyurethanes, poses a low risk of harm.
A 60-day public consultation ends on 2 May 2018.
The assessment concludes that IPDI poses no harm because not enough enters the Canadian environment. The assessment said that the quantities and concentrations do not have a long-term harmful effect on the environment or its diversity. The level of exposure does not pose a danger to human life or health in Canada.
Health Canada said that the material falls outside the scope of the Canadian Environmental Protection Act. This is in contrast to Europe, where it has category 1 respiratory sensitisation classification.
IPDI was identified as a priority for assessment on the basis of potential health concerns. It is not made in Canada, but it is used in paints, coatings, adhesives, sealants and floor coverings.
