Description of key information

logPow= 1.8 at 23 °C at pH7
(estimated value based on individual solubilities)

Key value for chemical safety assessment

Additional information

The determination was carried out by flask method based on the ETAD method.

This standard method was developed by intensive cooperation with the ETAD (Ecological and Toxicological Association of Dyes and Organic Pigments Manufacturers) and is regarded as acceptable for pigments by authorities.

The concentration of the pigment in n-octanol and in water was determined by HPLC-UV.

The presented logPow value was calculated based on individual solubilities.
