Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

For solubility in water, OECD 105 was used as a starting point. To determine if the experiment should be outsourced to a contract lab using a qualified test method, preliminary experiments were conducted. Three lots were assessed with one replicate per lot (PF 264, PF 312, PF 321- storage condition minus 20 °C). The experiments were conducted using transaminase enzyme lyophilized powder in distilled water at 22 °C. With the initial aliquot of powder added to distilled water, there was an extremely small amount of insolubility from a component in the powder. As additional powder was added, the insoluble component increased – this continued until the mixture became a paste. Therefore, no water solubility value is reported.
