  • Composite gel microparticles as active principle carriers
    Patent number: 6180141
    Abstract: The invention relates to vectors for delivering medicinal, nutritional, plant-protection or cosmetic active principles, these delivery particles being of small, controllable and adjustable particle size, which protect the active principle, and being biocompatible, biodegradable, non-immunogenic, stable and free of solvent. The particles do not denature the active principle and allow the active principle to be released. The microparticles of the invention are of a cohesive structure made of a physicochemically stable and integral composite gel which includes an oil such as coconut oil, an aqueous phase and a linear, non-crosslinked copolyamino acid of Leu/Glu type (random or diblock). The microparticles have a controllable and adjustable size of between 0.05 and 500 &mgr;m.

  • Particles based on polyamino acid(s) and capable of being used as delivery vehicles for active principle(s) and method for preparing them
    Patent number: 5904936
    Abstract: The present invention relates to delivery vehicles which are useful for the administration of active principles (APs), preferably medicinal or nutritional active principles, in particular via the oral or parenteral route.The technical problem solved by the invention is that which consists in providing delivery vehicles composed of (nano)- or (micro)particles based on polyamino acids, and which are invert with respect to the AP (proteins), of controllable particle size, strong and inexpensive.According to the invention, the particles have an average size of less than 200 .mu.m and consist of a polyamino acid of the Leu/Glu type, in which Leu/Glu+Leu.gtoreq.3% and the M.sub.w .gtoreq.4,000 D.
