PREPARATION OF POWDERS CONTAINING COLLOIDAL PARTICLES
摘要
The invention discloses a method for preparing a powder from an aqueous liquid which comprises colloidal particles. The method is based on the use of dense-phase extraction media, i.e. near-critical or supercritical fluids. The powder obtained through the method can be reconstituted with an appropriate aqueous liquid to yield a colloidal dispersion. The method is particularly useful for drying and stabilising aqueous colloidal dispersions comprising an active compound, such as a drug substance.
