- Conclusions:
- According to test method ISO 13320:2009, the volume mean diameter of Formononetin is 59.18 μm and its 90%, 50% and 10% cumulative size distributions are 146.9 μm, 32.97 μm and 7.65 μm respectively.
Reference
The particle size distribution was determined using the laser diffraction method with dry dispersion. The instrument detected the size distribution and generated a mean value and size distributions automatically.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
