Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a thin-film nanostructure composed of a polymeric amphiphilic blend with a high concentration of the organic core for use against ultraviolet radiation, belonging to the field of cosmetics and pharmaceutical preparations of active substances characterised by special physical forms, involving three phases: an organic phase, an aqueous phase and an aqueous dilution phase, wherein in the organic phase an organic solvent such as ketones, esters and alcohols is used, or a combination of two or more of these substances, wherein the hydrophobic polymer, the organic chemical agents against U.V. radiation, the hydrophilic copolymer and a non-ionic surfactant are added individually; the aqueous phase is prepared with distilled water and a surfactant such as lauryl ether sodium sulphate or cocoamidopropyl betaine or coconut fatty acid diethanolamide or sorbitan laurate 80 EO, or cetyl phosphate; and the dilution phase is prepared with distilled water and surfactants, such as lauryl ether sodium sulphate or cocoamidopropyl betaine or coconut fatty acid diethanolamide or sorbitan laurate 80 EO. La présente invention concerne un procédé de production d'une nanostructure à film mince constituée d'un mélange amphiphile polymère à haute concentration de noyau de nature organique, pour utilisation contre le rayonnement ultraviolet, relevant du secteur des produits cosmétiques et des préparations pharmaceutiques de substances actives se caractérisant par des formes physiques spéciales impliquant trois phases : organique, aqueuse et phase aqueuse de solution, avec utilisation dans la phase organique d'un solvant organique tel que des cétones, des esters et des alcools, ou encore la combinaison d'au moins deux de ceux-ci, le polymère hydrophobe, le contenu organique d'agents chimiques contre le rayonnement UV, le copolymère hydrophile et un tensioactif non ionique étant ajoutés individuellement. La phase aqueuse est préparée avec de l'eau distillée et un tensioactif du type lauryléthersulfate de sodium ou cocoamidopropybétaïne ou diéthanolamide d'acide gras de coco ou laurate de sorbitane 80 EO, ou cétyl phosphate ; et la phase de dilution est préparée avec de l'eau distillée et des tensioactifs, tels que le lauryléthersulfate de sodium, ou la cocoamidopropylbétaïne ou le diéthanolamide d'acide gras de coco ou laurate de sorbitane 80 EO. A presente invenção refere-se a um processo de produção de nanoestrutura de película
