Abstract

La presente invencion se refiere a las nanoparticulas micelares y a los métodos de su produccion. Las nanopartículas micelares se elaboran hidratando una mezcla de un aceite, un estabilizador/tensoactivo y un iniciador alcoholico con una solucion acuosa. Estas nanopartículas micelares normalmente son de diámetro inferior a 100 nanometros. Las nanopartículas son particularmente ventajosas para suministrar materiales como estradiol por vía topica a través de la piel debido a que su tamaño pequeño permite la fácil penetracion.
