Description of key information
The octanol-water partition coefficient for C.I. Direct Blue 264 was calculated according to its definition as quotient of n-octanol and water because the investigation following the standard guidelines was technically not feasible. The partition coefficient is calculated based on the 1-octanol solubility and the water solubility of C.I. Direct Blue 264 determined by HPLC.
Therefore the calculated octanol-water partition coefficient (log Pow) of C.I. Direct Blue 264 at 20°C is <-0.2 (Pow = 0.7).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -0.2
- at the temperature of:
- 20 °C
Additional information
The calculated octanol-water partition coefficient (log Pow) of C.I. Direct Blue 264 at 20°C is <-0.2 (Pow = 0.7).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
