Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
13 September 1999 to 6 January 2000
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose:
reference to same study
Qualifier:
according to
Guideline:
OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
GLP compliance:
yes
Type of method:
microscopic examination
Type of distribution:
mass based distribution
Percentile:
D50
Remarks on result:
other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.

The results indicate that 0.2% by mass of HP-10 is smaller than 10μm.

Conclusions:
The results indicate that 0.2% by mass of HP-10 is smaller than 10 μm.
Executive summary:

A study was performed to determine particle size distribution of HP-10. The method followed was OECD Guidelines for the Testing of Chemicals, Method 110.

 

The particle size distribution was initially examined using sieve analysis. As greater than 10% by weight of the test substance was found to pass a 75 micron sieve, it was further examined by image analysis.

 

The results indicate that 0.2% by mass of HP-10 is smaller than 10μm.

Description of key information
