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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2/20/2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study not conducted under GLP
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- GLP compliance:
- no
- Type of method:
- HPLC method
- Partition coefficient type:
- octanol-water
- Key result
- Type:
- log Pow
- Partition coefficient:
- 4.1
- Temp.:
- 20 °C
- Remarks on result:
- not measured/tested
- Remarks:
- The 4.1 is an average of two constituents which have a log Kow of 4 and 4.2. The pH is not considered critical in absence of acidic or basic groups
- Details on results:
- Floralozone consits of 2 constituents, which are only different by an ethyl group which is either para or ortho-substituted on the phenyl ring. It cannot be deduced which log Kow belongs to which constituent. Therefore an average of both values is used for the risk characterisation.
- Conclusions:
- The partition coefficient of Floralozone has been determined as log P =4-4.2 at 25°C under a study equivalent to OECD Guideline 117 (HPLC method) in a reliable non-GLP study. Floralozone consits of 2 constituents, which are only different by an ethyl group which is either para or ortho-substituted on the phenyl ring. It cannot be deduced which log Kow belongs to which constituent. Therefore an average of both values is used for the risk characterisation.
- Executive summary:
The partition coefficient of Floralozone has been determined as log P =4-4.2 at 25°C under a study equivalent to OECD Guideline 117 (HPLC method) in a reliable non-GLP study. Floralozone consists of 2 constituents, which are only different by an ethyl group which is either para or ortho-substituted on the phenyl ring. It cannot be deduced which log Kow belongs to which constituent. Therefore an average of both values is used for the risk characterisation.
