In the present work, vesicles made with soy lecithin and a commercial mixture of alkyl polyglucosides were prepared and characterized. Vesicles with a constant amount of soy lecithin and an increasing amount of a decylpolyglucoside surfactant, (OrNS10), were formulated and their physicochemical properties were studied with the airn to design a drug delivery system suitable for different applications. To this put-pose, morphology, size distribution, zeta-potential and apparent viscosity of the prepared vesicles were studied. Vesicles were also characterized by using optical and light polarized microscopy, transmission electron microscopy and photon correlation spectroscopy. A stability study was also performed by checking mean size and C-potential value variation of the several formulations during 4 weeks. Moreover, theoretical advances on geometric and thermodynamic aspects related to lipid vesicle formation were applied to this study. (c) 2007 Elsevier B.V. All rights reserved.

Abstract
In the present work, vesicles made with soy lecithin and a commercial mixture of alkyl polyglucosides were prepared and characterized. Vesicles with a constant amount of soy lecithin and an increasing amount of a decylpolyglucoside surfactant, (OrNS10), were formulated and their physicochemical properties were studied with the airn to design a drug delivery system suitable for different applications. To this put-pose, morphology, size distribution, zeta-potential and apparent viscosity of the prepared vesicles were studied. Vesicles were also characterized by using optical and light polarized microscopy, transmission electron microscopy and photon correlation spectroscopy. A stability study was also performed by checking mean size and C-potential value variation of the several formulations during 4 weeks. Moreover, theoretical advances on geometric and thermodynamic aspects related to lipid vesicle formation were applied to this study. (c) 2007 Elsevier B.V.
