- Executive summary:
This test using the procedures outlined in the NOTOX Study Plan for 487467, OECD 107 and EU Method A.8.
The estimation method was used for the determination of the Pow of Everzol Red CDN Crude. The water solubility of Everzol Red CDN Crude was 258 g/l and a solubility of Everzol Red CDN Crude in octanol of < 5 × 10-3g/l. The Pow, calculated as the quotient of the octanol and water solubility, is < 1.9 × 10-5. Therefore, the log Pow of Everzol Red CDN Crude was < -4.7.
Reference
The water solubility of Everzol Red CDN Crude was 258 g/l. Taking the dilution factor of the samples into account it corresponds with a solubility of Everzol Red CDN Crude in octanol of < 5 × 10-3g/l. The Pow, calculated as the quotient of the octanol and water solubility, is < 1.9 × 10-5.
Description of key information
The log Powof Everzol Red CDN Crude was < -4.7 (OECD TG107 and EU Method A.8).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -4.7
- at the temperature of:
- 20 °C
Additional information
The estimation method was used for the determination of the Pow of Everzol Red CDN Crude. The water solubility of Everzol Red CDN Crude was 258 g/l and a solubility of Everzol Red CDN Crude in octanol of < 5 × 10-3g/l. The Pow, calculated as the quotient of the octanol and water solubility, is < 1.9 × 10-5. Therefore, the log Pow of Everzol Red CDN Crude was < -4.7.
