Description of key information
log Kow < -3.5 based on concentration of test substance below limit of quantification
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -3.5
- at the temperature of:
- 25 °C
Additional information
The limit value is based on the concentrations in the
n-octanol phase being below the detection limit of the
analytical method used. The value quoted is for the 2:1
water/octanol volume ratio. The values for the 1:1 and 1:2
volume ratios are <-3.8 and <-3.2, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
