    摘要: The invention relates to microcapsules with a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, and to processes for the manufacture of the said microcapsules. According to the invention, the microcapsules comprise a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, the proportion of polyholosides, for example glycosaminoglycans, relative to the atelocollagen preferably being between 18 and 50% by weight. These microcapsules can be manufactured either by a process involving interfacial crosslinking or by the extrusion of a laminar flow which is broken up by vibrations into individual droplets, which fall into a crosslinking bath. These microcapsules are biocompatible by virtue of the presence of atelocollagen, which has most of the advantageous properties of collagen, namely a very low antigenicity and a perfect biodegradability. They are therefore particularly suitable for the manufacture of cosmetic, pharmaceutical or food compositions.
