Administrative data

Endpoint:
particle size distribution (granulometry)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is marketed or used in a non solid or granular form
Justification for type of information:
According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 18 December 2006 (CORRIGENDA), this study does not need to be conducted if the substance is marketed or used in a non solid or granular form. This substance is manufactured in a 50% aqueous solution and used usually in a much more diluted aqueous solution.
