Background

Four other substances were identified as being a part of the Alkyl Imidazolines and Salts Group at the outset of the third phase of the CMP. Two of these substances were subsequently determined to be of low concern to both human health and the environment, through other approaches. The conclusion for CAS RN 21652-27-7 is provided in the Final Screening Assessment of 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 conclusion for CAS RN 31135-57-6 is provided in the Final Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure. CAS RNs 67633-57-2 and 68122-86-1 will be assessed in a future screening assessment.
