Description of key information
The determination of the partition coefficient (n-octanol/water) was based on OECD Guideline no. 117: "Partition Coefficient (n-octanol/water) High Performance Liquid Chromatographic (HPLC) method" (1989).
In the HPLC chromatograms of 3-hydroxy-1,1-dimethylbutyl 2-ethyl-2-methylheptaneperoxoate , using detection at 210 nm, one large and 4 smaller test substance peaks were observed. It was assumed that the large peak derived from the major component of test substance whereas the small peaks derived from impurities.
The corresponding Pow values were calculated to be 1.58x10E04 (log Pow = 4.2) for the major component.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.2
- at the temperature of:
- 23 °C
Additional information
The determination of the partition coefficient (n-octanol/water) was based on OECD Guideline no. 117: "Partition Coefficient (n-octanol/water) High Performance Liquid Chromatographic (HPLC) method" (1989).
In the HPLC chromatograms of 3-hydroxy-1,1-dimethylbutyl 2-ethyl-2-methylheptaneperoxoate, using detection at 210 nm, one large and 4 smaller test substance peaks were observed. It was assumed that the large peak derived from the major component of test substance whereas the small peaks derived from impurities.
The corresponding Pow values were calculated to be 1.58x104(log Pow = 4.2) for the major component and 2.00x104(log Pow = 4.3), 3.16x104(log Pow = 4.5), 5.01x104(log Pow= 4.7) and 39.8x104(log Pow = 5.6) for the impurities.
The test was performed at 22.7-22.9°C.
