Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
