  • Particles, especially microparticles or nanoparticles, of crosslinked monosaccharides and oligosaccharides, processes for their preparation and cosmetic, pharmaceutical or food compositions in which they are present
    Patent number: 6197757
    Abstract: Particles comprising an outer wall formed of one or more saccharide components selected from the group consisting of monosaccharides and oligosaccharides crosslinked by interfacial crosslinking in emulsion, preferably at room temperature, with a polyfunctional acylating crosslinking agent to produce ester linkages between the acylatable hydroxyl group(s) of the primary alcohol(s) of the saccharide component and the acyl groups of the polyfunctional acylating agent. These particles can be used for the manufacture of cosmetic, pharmaceutical and food compositions.

  • Particles prepared by transacylation reaction between an esterified polysaccharide and a polyamine, methods of preparation therefor and compositions containing same
    Patent number: 5635609
    Abstract: Particles, preparation methods therefor, and compositions containing same. The particles include at least one esterified polysaccharide and at least one polyamine, as well as at least one gellable polysaccharide when neither the esterified polysaccharide nor the polyamine can be gelled under the selected operating conditions. Said particle includes, at least on its surface, a membrane consisting of the product of the transacylation reaction between the esterified polysaccharide and said polyamine within an optionally gellable gel, said reaction causing the formation of covalent amide bonds. Such particles may be used to encapsulated various active principles useful in the fields of cosmetics, pharmaceuticals and agri-foodstuffs, enzymes, cells and micro-organisms.
