| 摘要 |
<p>The invention concerns an improved method for avoiding the degradation of an active principle. The invention is characterised in that the active principle is incorporated inside multilamellar vesicles with an onion-like structure and consisting, from the periphery towards the centre, concentric membranes in the form of double layers comprising at least a surfactant, said membranes being separated by an interstitial liquid, said vesicles containing at least an agent for avoiding degradation of said active principle. The invention is more particularly applicable to the stabilisation of products sensitive to oxidation, reduction or hydrolysis and to products sensitive to more specific degradation reactions such as enzymes. The invention also concerns compositions containing said multilamellar vesicles and their method of preparation.</p> |
