Abstract: This invention relates to a biomaterial comprising an injectable bioresorbable polysaccharide composition wherein the polysaccharide may be succinochitosan glutamate. This invention also relates to a biomaterial comprising an injectable bioresorbable polysaccharide composition in which resorbable particles may be in suspension, the said particles comprising or consisting essentially of chitin and/or chitosan, which may be free of any additional formulation modifying agents, and a process for manufacturing the same. This invention also relates to a medical device including said biomaterial and to a method of repair or treatment including the filling of cavities in the human face or body.

Abstract: Microcapsules involving a wall of chitin or chitin derivatives or of polyhydroxylated polyamines or one of their salts, with the wall sheathing a hydrophobic substance, are prepared by forming a hydrophobic phase emulsion of the hydrophobic substance in an aqueous phase containing an anionic surfactant capable of causing insolubilization of chitosan or chitosan derivatives or polyhydroxylated polyamines, mixing the emulsion with a chitosan or chitosan derivative or polyhydroxylated polyamine organic salt so as to cause the coacervation of the chitosan or the chitosan derivatives or the polyhydroxylated polyamines around the droplets of the hydrophobic phase, subjecting the chitosan or chitosan derivative or the polyhydroxylated polyamine coacervate to an acetylation or crosslinking reaction and recovering the microcapsules, and are applicable to cosmetic compositions incorporating sunscreens.
