Temp.:
25 °C
Remarks on result:
other: pH not provided in the study report
Details on results:
The pH is assessed not to be critical based on the absence of acidic and basic structural features of TERPINEOL BAJA DENSIDAD and in its molecular structure.
Conclusions:
The partition coefficient of the representative of the Terpene Hydrocarbon Alcohols has been determined as log P = 3.5 - 5.5 at 25°C in a study equivalent to OECD Guideline 117 (HPLC method) in a reliable non-GLP study.
Executive summary:

The partition coefficient of the representative of the Terpene Hydrocarbon Alcohols has been determined as log P = 3.5 - 5.5 at 25°C in a study equivalent to OECD Guideline 117 (HPLC Method).

Description of key information

The partition coefficient of the representative of the Terpene Hydrocarbon Alcohols has been determined as log P = 3.5 - 5.5 at 25°C in a study equivalent to OECD Guideline 117 (HPLC Method).In this study the lower Kow values represent the Alcohol-type, Ketone type and Ether type. The higher log Kow represents the Solely hydrocarbon type constituents of which Terpinolene is the key constituent. On the ECHA website the measured log Kow is 4.2 - 4.5. An average measured Terpinolene log Kow value of 4.9 ((4.3+5.5)/2) is used as key value.
