Background

Seven other substances were identified as being a part of the Epoxides and Glycidyl Ethers 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 RNs 61788-72-5, 61789-01-3, 68082-35-9 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 RNs 101-90-6, 556-52-5, 28768-32-3, 66072-38-6 are provided in the Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.
