The related notice was published in the Canada Gazette, Part I: Vol. 152, No. 49.|
A seventh substance, (CAS RN 632-99-5) was initially identified as being part of the Triarylmethanes Group at the outset of the third phase of the CMP. This substance was subsequently determined to be of low concern to both human health and the environment, through other approaches. Conclusions for this substance are provided in the Draft Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.
