study well documented, meets generally accepted scientific principles, acceptable for assessment

Principles of method if other than guideline:

Counting apparatus

GLP compliance:

no

Type of method:

other: counting

Type of distribution:

volumetric distribution

No.:

#1

Size:

< 10 µm

Distribution:

ca. 3 %

Please see distribution curve (attachment).

Executive summary:

Particle size distribution of finely ground sodium p-chloro-m-cresolate (hydrated form) was determined by counting apparatus. Ca. 3 % (volumetric) of the particles are smaller than 10 µm in diameter.

Description of key information

The substance is hygroscopic and the particles aggregate.

Particles with diameter < 10 µm: ca. 3 % (v/v) (finely ground material)

Additional information

Particle size distribution of finely ground sodium p-chloro-m-cresolate (hydrated form) was determined by counting apparatus. Ca. 3 % (volumetric) of the particles are smaller than 10 µm in diameter.

A further study does not need to be conducted because the experience in production and handling shows that the substance is hygroscopic and the particles aggregate.
