PCT No. PCT/FR91/00640 Sec. 371 Date Feb. 9, 1993 Sec. 102(e) Date Feb. 9, 1993 PCT Filed Aug. 2, 1991 PCT Pub. No. WO92/02254 PCT Pub. Date Feb. 20, 1992.The invention relates to microcapsules having a combined atelocollagen/polyholoside coagulated wall as well as to a method for producing them. According to the invention, the microcapsules are characterized in that they include a combined atelocollagen/polyholoside wall coagulated by a coagulant, preferably a divalent cation. These microcapsules are preferably prepared by a method which includes laminar-flow extrusion dislocated by individual droplet vibrations falling into a coagulation bath. The presence of the atelocollagen renders the microcapsules biocompatible. They are particularly suitable for the production of cosmetic, pharmaceutical or food compositions.
