Two other substances were identified as being part of the Resins and Rosins Group at the outset of the third phase of the CMP. These substances were subsequently determined to be of low concern to both human health and the environment, through other approaches. Conclusions for CAS RN 26266-77-3 are provided in the Screening Assessment for Substances Identified as Being of Low Concern based on the Ecological Risk Classification of Organic Substances and the Threshold of Toxicological Concern (TTC)-based Approach for Certain Substances. Conclusions for CAS RN 91081-53-7 are provided in the Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.
