Abstract

Proceso de producción de una nanoestructura de película delgada de mezcla anfifílica polimérica con alta concentración de núcleo de carácter orgánico para aplicación contra la radiación ultravioleta, que comprende tres fases: orgánica, acuosa y fase acuosa de dilución, donde en la fase orgánica se utiliza un solvente orgánico como cetonas, ésteres y alcoholes, o también una combinación de dos o más de estos, donde es aumentado individualmente el polímero hidrófobo, el contenido orgánico de agentes químicos contra la radiación UV, el copolímero hidrófilo, y un tensioactivo no iónico; la fase acuosa es preparada con agua destilada y tensioactivo del tipo lauril éter sulfato de sodio o cocoamidopropilbetaína o dietanolamida de ácido graso de coco o laurato de sorbitano 80 EO, o cetil fosfato; y la fase de diluciones preparada con agua destilada y tensioactivos, como lauril éter sulfato de sodio, o cocoamidopropilbetaína o dietanolamida de ácido raso de coco o laurato de sorbitano 80 EO. Reivindicación 6: Proceso de producción de una nanoestructura de película delgada de mezcla anfifílica polimérica con alta concentración de núcleo de carácter orgánico para aplicación contra la radiación ultravioleta, de acuerdo con la reivindicación 5, caracterizado porque se utiliza para la constitución de la envuelta-núcleo una mezcla del polímero hidrófobo policaprolactona mezclado con los copolímeros hidrófilos de polioxietileno o polioxipropileno, y la combinación de al menos dos agentes químicos de protección contra la radiación ultravioleta para la constitución del núcleo.Production process of a thin film nanostructure of polymer amphiphilic mixture with high concentration of organic core for application against ultraviolet radiation, comprising three phases: organic, aqueous and dilution aqueous phase, where in the organic phase a organic solvent such as ketones, esters and alcohols, or also a combination of two or more of these, where the hydrophobic polymer, the organic content of chemical agents against UV radiation, the hydrophilic copolymer, and a non-ionic surfactant are individually increased; the aqueous phase is prepared with distilled water and surfactant such as sodium lauryl ether sulfate or cocoamidopropyl betaine or coconut fatty acid diethanolamide or sorbitan laurate 80 EO, or cetyl phosphate; and the dilution phase prepared with distilled water and surfactants, such as sodium lauryl ether sulfate, or cocoamidopropyl betaine or coconut satin acid diethanolamide or sorbitan laurate 80 EO. Claim 6: Production process of a thin film nanostructure of polymer amphiphilic mixture with high concentration of organic core for application against ultraviolet radiation, according to claim 5, characterized in that it is used for the constitution of the core-shell a mixture of the hydrophobic polycaprolactone polymer mixed with the hydrophilic copolymers of polyoxyethylene or polyoxypropylene, and the combination of at least two chemical ultraviolet radiation protection agents for the constitution of the core.
