Document Type and Number:
Japanese Patent JP2002523584
Kind Code:
A
Abstract:
The invention relates to a method for the production of spherical microparticles consisting totally or partly of at least one water-insoluble polysaccharide, wherein the at least one water-insoluble polysaccharide is dissolved in a solvent or solvent mixture, the solution thus formed is introduced into a precipitating agent or precipitating agent mixture, the mixture obtained is optionally cooled and the formed microparticles are separated. The invention is characterized in that the water-insoluble polysaccharide is selected from a polyglucan containing branches with a degree of branching higher than zero and no higher than 8% and a mixture of a polyglucan containing branches and a linear polysaccharide, wherein the proportion of polyglucan containing branches in the mixture is at the most 30% by weight in relation to the overall weight of the polysaccharide and the polyglucan.
