Abstract
The present invention relates to novel spherical agglomerates of 10-phenothiazinylpropanoic acid. The invention also relates to a process for obtaining those agglomerates. The process for preparing the spherical agglomerates of 10-phenothiazinylpropanoic acid is characterized by stirring a suspension of 10-phenothiazinylpropanoic acid in water in the presence of a binder liquid which is not miscible with water selected from esters of aliphatic or cycloaliphatic acids, aliphatic or cycloaliphatic alcohols, and aliphatic or cycloaliphatic ketones.
