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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- not specified
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP status not known, information from a published handbook, acceptable with restrictions
- Justification for type of information:
- N/A
- Principles of method if other than guideline:
- The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to Exploring QSAR, Hydrophobic, Electronic and Steric Constants states that it is an extensive compilation of published data. Each record is evaluated and the preferred value is identified for each substance. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.
- GLP compliance:
- not specified
- Remarks:
- no data reported
- Type of method:
- shake-flask method to: flask method
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- not specified
- Key result
- Type:
- log Pow
- Partition coefficient:
- 1.13
- Temp.:
- 25 °C
- pH:
- 7
- Details on results:
- No further details provided. Temperature and pH are assumed
- Conclusions:
- The log kow of ethylene is 1.13
- Executive summary:
No information on the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

Additional information
The Handbook by Hansch et al. (1995) is peer reviewed and is considered reliable and acceptable for use as a key study for this endpoint. The supporting study (Meylan and Howard 1995) is a peer reviewed QSAR and reports a value of 1.27 and supports the value reported in the key study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
