OTTAWA, Ont. — The Canadian government published a preliminary assessment last month proposing the elimination of three silicon-based chemicals including D5, the main ingredient in GreenEarth solvent.
The assessment identified octoamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5) and dodecamethylcyclohexasiloxane (D6) silicones and a phenol derivative as meeting toxicity criteria sufficient to require elimination under Canadian law.
