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 conclusions for CAS RN 21652-27-7 are provided in the 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 conclusions for CAS RN 31135-57-6 are provided in the Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure. Proposed conclusions for CAS RNs 67633-57-2 and 68122-86-1 will be provided in a future screening assessment.
