- Remarks:
- hypothesis As a hypothesis, methanol is the critical constituent of the substance (S-Ethanol, composition 2) based on its amount and with regards to its hazardous properties. It is the major constituent affecting the classification and labeling of the target substance (S-Ethanol). Therefore, data from methanol is used in the read-across approach in order to update the hazard assessment of this substance. Other impurities are taken into account for self-classification but there were no need to consider evaluating their properties in hazard assessment because of low concentrations. Analogue approach justification This substance (S-Ethanol, composition 2) has degree of ethanol purity between 76.4-81.9 %. Methanol is the main impurity of the target substance (conc. 13-14 %), and considered the major driver for adverse effects based on its properties and relative quantity in the substance. For chemical safety assessment certain physico-chemical properties are relevant for both human health and environmental health assessment. Also they are important for self-classification and for updating of the exposure assessment of the target substance. For toxicological endpoints, methanol is considered the major drivers for classification and overall safety assessment of the target substance. Therefore, methanol properties were included for chemical safety assessment and the endpoint robust summaries were provided also for methanol.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
