Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 200-578-6 | CAS number: 64-17-5
Adsorption / desorption
Administrative data
- Endpoint:
- adsorption / desorption
- Remarks:
- adsorption
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Accepted calculation method Hypothesis and analogue approach for read-across: This substance (S-Ethanol, composition 2) has degree of ethanol purity between 76 - 82%. 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. Therefore, testing of the substance itself was considered unnecessary. Instead the available REACH registration data of ethanol and methanol is used in order to update the chemical safety assessment of this substance. Other impurities of this substance are taken into account for self-classification, but there is no need to consider their properties in hazard assessment because of low concentrations (see IUCLID section 1.2; composition 2).

The very low value of the estimated Koc indicates no significant adsorption of methanol on soils.
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.
