Description of key information

Key study: Test method according to OECD Guideline 110 and CIPAC MT 170. GLP study. The mass moment mean of the test substance was determined to be 197.85 µm. 

Additional information

Key study: The determination of particle size distribution was carried out using dry sieve test in accordance with CIPAC MT 170 and OECD Guideline 110, following the Principles of GLP. The results obtained were as follows:

The results obtained were as follows; over 2000µm: 0.00%, fraction 1000 - 2000µm: 0.15%, fraction 500 - 1000µm: 0.41%, fraction 250 - 500µm: 20.48%, fraction 25 - 250µm: 46.84%, fraction 75 - 125µm: 22.99%, fraction 45 - 75µm: 7.31%, under 45µm: 1.83%.

The mass moment mean of the test substance was determined to be 197.85µm.
