Description of key information
The mass median diameter: Promaxon T, 35.700µm. Promaxon: 61.253 µm.
Additional information
The granulometry of crystalline calcium silicate hydrates (xonotlite - tobermorite) was investigated according to OECD guideline 110 under GLP using the sedimentation method. This test was disregarded.
The granulometry of Promaxon T was determined with a Mastersizer 2000. The mass median diameter was found to be 35.700 µm. No particles were found under 0.417 µm and above 316.228 µ under the conditions of this test.
