Description of key information

The partition coefficient n-octanol/water of the test item Vat Blue 66 was estimated based on the ratio of the individual solubilities of the test item in water and n-octanol. The solubilities were determined according to the flask method.

It was found to be:

log POW~-0.1(1)

([1])The partition coefficient calculated with the program KOWWIN (part of EPI Suite) was 10.5.

Key value for chemical safety assessment
