Microcapsules having a combined atelocollagen/polyholoside wall coagulated by a divalent cation and method for manufacturing these microcapsules and cosmetic or pharmaceutical or food compositions containing them
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.
