Canada imposes notification requirements for paint additive


The Canadian government has imposed notification requirements for certain new uses of the paint additive calcium 2-ethylhexanoate.

Canada determined in 2018 that the substance is not harmful at current levels of exposure but could become concerning to human health with increased use, given its potential developmental effects. It therefore proposed to impose significant new activity (Snac) requirements to allow the government to assess the risk of certain new uses before allowing them.

Published in the Canada Gazette on 17 August, the Snac requires notification for the use of calcium 2-ethylhexanoate in a cosmetic or consumer product above 0.1% by weight, with exceptions for stains and coatings that dry as a solid film and have a concentration under 0.5% by weight. Importation above 10kg per year for such uses also requires submission of a significant new activity notice (Snan).

Calcium 2-ethylhexanoate – also called hexanoic acid, 2-ethyl-, calcium salt – is used in Canada as an additive in interior and exterior paints, as a formulant in antifouling paints and as a ‘no-rinse’ aid in commercial dishwashers. It also has uses in the manufacture of food packaging materials, including resins and printing inks.
