UNIFORMLY DISPERSIBLE CROSSLINKED GELATIN PARTICLE AGGREGATE

Title:

UNIFORMLY DISPERSIBLE CROSSLINKED GELATIN PARTICLE AGGREGATE

Document Type and Number:

Japanese Patent JP2014218464

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a crosslinked gelatin particle aggregate which is constituted by encapsulating a given amount of crosslinked gelatin particles with a fine particle diameter using water-soluble gelatin, wherein crosslinked gelatin particles can uniformly disperse by increased solution viscosity due to dissolving water-soluble gelatin into a medium by dissolving into an aqueous medium such as physiological salt solution at the time of use.SOLUTION: A given amount of crosslinked gelatin particles with an average particle diameter of 10-500 μm are encapsulated with water-soluble gelatin. A jelly strength of the water-soluble gelatin is preferred to be 300 g or less, and the encapsulating amount is preferred to be 2-5 times of the encapsulated crosslinked gelatin particle weight. The crosslinked gelatin particles are preferred to be tablet shape by package coating with water-soluble gelatin or by dispersing in a water-soluble gelatin layer.
