Organogel nanoparticles as delivery system for lipophilic drugs

In recent years, a growing interest has emerged in the development of semi-solid colloidal careers for the delivery of water-insoluble drugs. Solid Lipid Nanoparticles (SLN) and Nanostructured Lipid Careers (NLC) are example of such systems. As an alternative to SLN, we propose the use of an original family of organogel nanoparticles. Organogels are semi-solid materials in which an organic solvent (e.g., vegetable oil) is entrapped in the three-dimensional fibrous network formed by self-aggregation of a low molecular mass organic gelator (12-hydroxystearic acid). The preparation process of the gelled oil nanoparticles is based on the sol-gel phase transition of the organogel obtained by hot emulsification (T°>T°gel) in presence of an aqueous solution of stabilizing agent (polyvinyl alcohol 80), leading to a stable semi-solid dispersion after cooling (T°
