dc.description.abstract | Ethylcellulose nano-emulsions have been obtained by the low-energy phase inversion composition method in the Water / [Alkylamidoammonium: Cremophor WO7] / [6% ethylcellulose in ethyl acetate] system at 25 °C. It is shown that nano-emlulsions’ composition variables (oil-to-surfactant ratio, cationic: nonionic surfactant ratio and polymer and water content) produce changes in their droplet diameter, surface charge and colloidal stability following defined trends. Nano-emulsions with good stability, droplet diameters between about 120 and 200 nm and surface charge from about 10 to 50 mV have been obtained. Nano-emulsions are further used as templates for nanoparticle dispersions preparation, which show sizes and surface charges typically smaller and similar respectively to their nano-emulsion templates. Cationic: nonionic surfactant ratio has the highest influence on both, size and surface charge, followed by oil-to-surfactant ratio and water content. Interestingly, the positive charge of the nanoparticles can be depleted under diluting conditions in a time-dependent manner. © 2019 Elsevier Ltd | es_ES |
dc.description.sponsorship | The DLS, zeta potential, viscosity and Turbiscan analyses have been performed at the Nanostructured Liquid Characterization Unit, located at the Institute of Advanced Chemistry of Catalonia (IQAC), belonging to the Spanish National Research Council (CSIC) and affiliated to the NANBIOSIS ICTS of the Biomedical Networking Center (CIBER-BBN). CIBER-BBN is an initiative funded by the VI National R&D&I Plan 2008-2011. Financial support from MINECO (grant CTQ2011-29336-C03-01 and CTQ2017-84998-P ) and Generalitat de Catalunya (grant 2017 SGR 1778 ) is acknowledged. S.L. is grateful to CIBER-BBN for a research scholarship. Colorcon and Bonderalia S.A./Quimivita S.A. are gratefully acknowledged for the gift of ethylcellulose and ricinoleamidopropyltrimonium methosulfate respectively. Appendix A | es_ES |
