Nano-and microparticles of gelled oils were prepared using an aminoacid-based low molecular weight organogelator and amphiphilic nonionic polysaccharides as stabilizers. The investigated oils were Tetralin, M810N and M829. The preparation procedure involved organogelator dissolution in hot solvent (150-190 °C) followed by oil-in-water emulsification at 70-80 °C in liquid state and final cooling step to room temperature to obtain gelled oil particles. The range of particle diameters (sub-micrometric or micrometric) could be adjusted by selecting the emulsification process, sonication or vortex mixing. Using sonication, organogel particles could be also prepared at room temperature with the oil phase in the gel form. The suspensions of gelled oil particles could be centrifuged and fully redispersed by vortex mixing with an increase of particle diameters whose extent depended on the nature of the oil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
