particle size distribution (granulometry)
Data waiving:

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

In accordance with Column 2 of REACH Annex VII, section 7.14., this study does not need to be conducted because the test item 1-methyl-1-phenlyethyl peroxyneodecanoate is only marketed as a liquid.

Additional information

1-methyl-1-phenlyethyl peroxyneodecanoate can only be marketed together with a phlegmatiser. The test item is a liquid and "pure" 1 -methyl-1 -phenlyethyl peroxyneodecanoate is never available without phlegmatiser due to the substance's thermal instability.
