Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 4/7/2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The information is derived from a reliable non-GLP in-house study according to OECD TG 117 (HPLC).
- 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:
- 4.4
- Temp.:
- 25 °C
- Remarks on result:
- other: pH not provided in the report but is not considered critical
- Type:
- log Pow
- Partition coefficient:
- 3.5
- Temp.:
- 25 °C
- Remarks on result:
- other: pH not provided in the study report, but not considered critical
- Type:
- log Pow
- Partition coefficient:
- 4.7
- Temp.:
- 25 °C
- Remarks on result:
- other: pH not provided in the study report but not considered critical
- Details on results:
- The pH is assessed not to be critical based on the absence of acidic and base structural features of PSEUDO LINALYLACET BHT and in its molecular structure. The log Kows cannot be well assigned to the peaks of the key constituents. The log Kow of 4.4 is considered to be a good representative of Pseudo linalyl acetate.
- Conclusions:
- The partition coefficient of PSEUDO LINALYLACET BHT has resulted in 3 log Kows 3.5, 4.4 and 4.7 at 25°C in a study equivalent to OECD Guideline 117 (HPLC method) in a reliable non-GLP study. The highest log Kow will be taken forward because this log Kow is associated with Myricenyl acetate, being the constituent with the highest concentration in the substance.
- Executive summary:
The partition coefficient of PSEUDO LINALYLACET BHT has been determined as log P = 3.5-4.7 at 25°C in a study equivalent to OECD Guideline 117 (HPLC Method). The highest log Kow will be taken forward because this log Kow is associated with Myricenyl acetate 'mono', being the constituent with the highest concentration in the substance.

Description of key information
The partition coefficient of PSEUDO LINALYLACET BHT has been determined as log P = 3.5 , 4.4 and 4.7 at 25°C in a study equivalent to OECD Guideline 117 (HPLC Method). These log Kow cannot be well assigned to key constituents, therefore the log Kow of 4.4 is considered a good representative for Pseudo linalyl acetate.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.4
- at the temperature of:
- 25 °C
