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

particles with diameter < 10 µm: ca. 3 % (v/v)

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.
