BackgroundThese 11 substances, as well as 2 other substances (CAS RNs 8001-04-5 and 68140-48-7), were identified as being part of the Musks (macro/poly cyclic) Group at the outset of the third phase of the CMP. CAS RNs 8001-04-5 and 68140-48-7 were subsequently determined to be of low concern to both human health and the environment, through other approaches. Conclusions for these 2 substances are provided in the Final Screening Assessment for Substances Identified as Being of Low Concern using the Ecological Risk Classification of Organic Substances and the Threshold of Toxicological Concern (TTC)-based Approach for Certain Substances. The remaining 11 substances are now referred to, under the CMP, as the Macrocyclic Lactones and Ketones, Ionones and Cyclohexanone Group.
