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

Description of key information

According to Column 2 of REACH Annex VII, section 7.14., this study does not need to be conducted because OO-tert-butyl monoperoxymaleate is placed on the market in a non-solid or granular form.

Additional information

OO-tert-butyl monoperoxymaleate as such is a solid. However, due to the thermal instability of the organic peroxide, it can only be marketed together with a liquid phlegmatizer and is never available as a "pure" solid.
