UTILIZATION OF A TRANSACYLATION REACTION BETWEEN AN ESTERIFIED POLYSACCHARIDE AND A POLYAMINATED OR POLYHYDROXYLATED SUBSTANCE FOR FABRICATING MICROPARTICLES, MICROPARTICLES THUS OBTAINED, METHODS AND COMPOSITIONS CONTAINING TH M

摘要

The invention relates to microparticles, particularly microcapsules and their fabrication method. Said microparticles, and particularly said microcapsules, are characterized in that they have a wall made of the product obtained from the reaction between a polysaccharide carrying esterified carboxylic groups and a polyaminated or polyhydroxylated substance, particularly through a transacylation reaction. Said microparticles or said microcapsules are useful for the fabrication of cosmetic, pharmaceutical or food product compositions.
