Description of key information
Based on dry sieve analysis of the test item Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc, more than 80 % of the test item was found to be bigger than 125 μm and no particles with a diameter below 11 μm. As only residues > 90% were determined, the range of the sieves with 10% < Rx < 90% could not be determined.
Additional information
The particle size distribution of Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc was determined following CIPAC MT 169 (Tap Density) and MT 170 (Dry Sieve Analysis). First, the tap density of the test item was calculated as 0.83 g/mL ( = g/cm3). In the following, the particle size distribution of Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc was determined by dry sieve analysis according to CIPAC MT 170. Six sieves of different mesh sizes were used. More than 80 % of the test item was found to be bigger than 125 μm. No particles with a diameter below 11 μm were found. As only residues > 90% were determined, the range of the sieves with 10% < Rx < 90% could not be determined.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
