Background
Two other substances (CAS RNs 1533-45-5 and 3426-43-5) were identified as being part of the Stilbenes 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 these two substances are provided in the Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.
