Title:
徐放性複合粒子、徐放性複合粒子の製造方法及び乾燥粉体
Document Type and Number:
Japanese Patent JP7147490
Kind Code:
B2
Abstract:
To provide: a novel easy-to-handle sustained-release composite particle that can maintain the effect of functional components for a long period of time while maintaining the characteristics of cellulose nanofiber; a method for producing said sustained-release composite particle; and a dry powder body containing said sustained-release composite particle.SOLUTION: The sustained-release composite particle 9 is a composite particle having a coating layer 2 composed of a micronized cellulose 1 on the surface of a core particle 3 containing at least one kind of polymer. The functional component is contained in the coating layer 2. The core particle 3 and the micronized cellulose 1 are combined and in an inseparable state.SELECTED DRAWING: Figure 2
