Description of key information

The test item has been considered to be essentially non-inhalable.

Additional information

The method used is based on a procedure designed to be compatible with that given in ‘Particle Size Distribution, Fibre Length and Diameter Distribution’, June 1996 European Commission technical guidance document, which satisfies the requirements of OECD Guideline 110, 12 May 1981.

Test item (15.11 g) was sieved for approximately 30 minutes on an Inclyno sieve shaker using a sieve with an aperture size of 100 µm. The mass of test item passing through the sieve was measured.

The proportion of test item having an inhalable particle size of less than 100 µm was determined to be 2.0%. The test item has been considered to be essentially non-inhalable.
