Description of key information

The test item Hydroxy(2-methylprop-2-enoato-O)zinc has a median particle size L50 = 7.45 µm, which was determined by laser diffraction measurement.

Additional information

Key study was performed in order to determine the particle size distribution of the test item Hydroxy(2-methylprop-2-enoato-O)zinc according to the OECD 110 and ISO 13320 using the laser diffraction method.

Three test series of 3 measurements each were performed with the fine fraction of the test item.

The test item Hydroxy(2-methylprop-2-enoato-O)zinc has a median particle size L50 = 7.45 µm

The result has been considered as reliable without restriction because the test was performed in compliance with OECD and EU guidelines giving scientifically valid results.
