Description of key information

WP30 solubility limit has been determined to be < 0.02 µg/l by an elution method according to EC A6.

Key value for chemical safety assessment

Additional information

Due to the low expected solubility of < 100 mg/ L an elution method was applied. This method is

based on the elution of a test substance with water from a micro-column which is charged with an inert support

material, such as glass beads or sand, coated with an excess of test substance. The water solubility is to be

determined when the mass concentration of the eluate is constant. The WP30 concentration in water was below the detection limit, and < 0.02 µg/l.
