DYNAMIC SUSPENSION DRYING (DSD) TO CONTROL OSTWALD RIPENING

The present invention relates to a process for the control of Ostwald Ripening phenomenon occurring in particle suspensions without the need for addition of stabilizing agents, by using high pressure homogenization at mild conditions in a way that no increase or decrease in particle size occurs, thu...

Beschreibung
Zusammenfassung:	The present invention relates to a process for the control of Ostwald Ripening phenomenon occurring in particle suspensions without the need for addition of stabilizing agents, by using high pressure homogenization at mild conditions in a way that no increase or decrease in particle size occurs, thus allowing the stabilization of the suspension during the isolation step in the form of a dried powder. La présente invention porte sur un procédé pour la lutte contre le phénomène de mûrissement d'Ostwald survenant dans des suspensions de particules sans avoir besoin d'ajouter des agents stabilisants, à l'aide d'une homogénéisation à haute pression dans des conditions douces d'une manière telle qu'aucune augmentation ou diminution de la dimension des particules n'a lieu, ce qui permet ainsi la stabilisation de la suspension pendant l'étape d'isolement sous la forme d'une poudre séchée.
