ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Una de las acciones recomendadas por organismos internacionales de salud para evitar contraer enfermedades de transmisión vectorial, es la aplicación de productos repelentes corporales. Estos productos, normalmente formulados en forma de lociones, deben aplicarse cada cuatro o seis horas dependiendo del tipo y concentración de la sustancia activa presente en su formulación. Este hecho hace que sea necesaria por parte de los usuarios de una atención constante y de una provisión de repelentes que pueden no resultar accesibles a todo el mundo, especialmente si hablamos de población local con escasos recursos. One of the actions recommended by international health organizations to avoid contracting vector-borne diseases is the application of repellent products. bodily These products, normally formulated in the form of lotions, should be applied every four to six hours depending on the type and concentration of the active substance present in its formulation. This fact makes it necessary for users of constant attention and a supply of repellents that may not be accessible to everyone, especially if we talk about local people with limited resources.
Además en la aplicación de repelentes se suele obviar una parte muy importante, como son los pies y, sobre todo los tobillos, donde la epidermis es más fina, y, por tanto, resulta un lugar muy apetecible para los mosquitos y, sobre todo, para los flebótomos que tienen un vuelo muy corto y bajo y prefieren esas zonas para conseguir la sangre con la que madurar sus huevos. Also, in the application of repellents, a very important part is usually obviated, such as the feet and, especially the ankles, where the epidermis is thinner, and, therefore, it is a very desirable place for mosquitoes and, above all, for the sandflies that have a very short and low flight and prefer those areas to get the blood with which to ripen their eggs.
Los mosquitos son transmisores de enfermedades como malaria, dengue, fiebre amarilla, virus del Nilo occidental y varias encefalitis. Los flebótomos son vectores de leishmaniosis cutánea y visceral. La nueva tecnología de microcápsulas poliméricas permite incorporar distintos principios activos como biocidas convencionales, reguladores del crecimiento de insectos, repelentes, atrayentes, moléculas naturales (aceites esenciales) en biopolímeros de liberación lenta que otorgan un elevado poder residual manteniendo la no interacción de los activos. La microencapsulación polimérica de los ingredientes activos se realiza en un polímero orgánico incorporado en una matriz activa de distintas cargas y pigmentos, que proporciona una liberación gradual y lenta de los activos aumentando su persistencia, siendo inocuo para el ser humano. Mosquitoes are transmitters of diseases such as malaria, dengue fever, yellow fever, West Nile virus and various encephalitis. The sandflies are vectors of cutaneous and visceral leishmaniasis. The new polymer microcapsule technology allows different active ingredients to be incorporated, such as conventional biocides, insect growth regulators, repellents, attractants, natural molecules (essential oils) in slow-release biopolymers that grant a high residual power while maintaining the non-interaction of the assets. The polymeric microencapsulation of the active ingredients is carried out in an organic polymer incorporated in an active matrix of different fillers and pigments, which provides a gradual and slow release of the active ingredients increasing their persistence, being harmless to the human being.
Todos los formulados de la microencapsulación polimérica incorporan la microcápsula, siendo ésta el elemento que confiere a los formulados toda sus especiales características. All the formulations of the polymeric microencapsulation incorporate the microcapsule, this being the element that gives the formulates all their special characteristics.
La formación de la microcápsula es un proceso químico, y da como resultado una suspensión de microcápsulas que oscilan entre 1 nanómetro y 300 micrómetros. The formation of the microcapsule is a chemical process, and results in a suspension of microcapsules ranging from 1 nanometer to 300 micrometers.
Esta microencapsulación se describe por ejemplo en las patentes de invención con números de publicación WO 2010130856 y ES 2350075, propiedad ambas del mismo titular que la invención que nos ocupa. La liberación progresiva y controlada de los activos microencapsulados se consigue gracias a que la naturaleza del polímero recubriente lo permite. This microencapsulation is described for example in the invention patents with publication numbers WO 2010130856 and ES 2350075, both owned by the same owner as the invention at hand. The progressive and controlled release of microencapsulated assets is achieved thanks to the nature of the coating polymer allows.
Los principales beneficios de los nuevos productos microencapsulados para el control vectorial son: - Elevada eficacia. The main benefits of the new microencapsulated products for vector control are: - High efficiency.
- Seguridad para el usuario y para el medioambiente, al basarse en sustancias no tóxicas y naturales. - Safety for the user and the environment, based on non-toxic and natural substances.
- Larga persistencia de acción, por la liberación lenta de los activos gracias a las microcápsulas poliméricas. - Ausencia de residuos tóxicos, con el consiguiente ahorro y simplificación en el manejo y reutilización de los materiales. - Long persistence of action, due to the slow release of assets thanks to polymeric microcapsules. - Absence of toxic waste, with the consequent saving and simplification in the handling and reuse of materials.
- Clasificación como producto ecológico, con el consiguiente interés para su uso en cualquier parte del mundo. - Classification as an organic product, with the consequent interest for its use anywhere in the world.

Se prevé por tanto que una parte del calzado, preferentemente su piso, incorpore una capa del mismo material que el que compone el propio piso del calzado "cargada" con la composición microencapsulada o no. Publication number WO 2010130856 and publication number ES 200930147, both records being property of the same owner as the invention at hand. It is therefore foreseen that a part of the footwear, preferably its floor, incorporates a layer of the same material as that which composes the footwear floor itself "loaded" with the microencapsulated composition or not.
En consecuencia es una carga con la composición biocida 3 ubicada en una parte del calzado, con el fin de que esta composición sea liberada de forma prolongada en el tiempo. Consequently, it is a load with the biocidal composition 3 located in a part of the footwear, so that this composition is released over time.
Para ello, se prevé que el propio usuario, en cada pisada, contribuya con la propia masa de su cuerpo, ejerza presión sobre el calzado y provocar así dicha liberación de la composición biocida. For this, it is expected that the user himself, in each step, contribute to his body's own mass, exert pressure on the footwear and thus cause said release of the biocidal composition.
En cuanto al método de fabricación, se prevén básicamente dos: Un primer método en el que se baña o impregna al menos parte del material polimérico que conforma el piso del calzado, con la composición biocida 3, para impregnar totalmente dicho piso que posteriormente liberará el producto biocida a través del tiempo. Regarding the manufacturing method, two are basically foreseen: A first method in which at least part of the polymeric material that forms the footwear floor is bathed or impregnated, with the biocidal composition 3, to completely impregnate said floor that will subsequently release the floor. Biocidal product over time.
Adicionalmente se realiza una fase de curado y secado del material. Additionally, a curing and drying phase of the material is carried out.
Un segundo método donde la composición biocida 3 (activos biocidas) se integra en la capa de material adhesivo 5 que se emplea para unir la plantilla 4 con el piso 1 del calzado. A second method where the biocidal composition 3 (biocidal assets) is integrated in the layer of adhesive material 5 that is used to join the insole 4 with the floor 1 of the footwear.
En este caso la composición podrá incluir un adhesivo según se concreta a continuación: In this case the composition may include an adhesive as specified below:
- Adhesivos de látex: látex vinílico o alcohol polivinílico. - Latex adhesives: vinyl latex or polyvinyl alcohol.
- Adhesivos sensibles a la presión: silicona, acrílico y caucho. - Adhesivos de fusión en caliente: termoplásticos. - Pressure sensitive adhesives: silicone, acrylic and rubber. - Hot melt adhesives: thermoplastics.
- Adhesivos reactivos. - Reactive adhesives.
Elastómeros: Caucho de estireno butadieno (SBR) o neopreno. Elastomers: Styrene Butadiene Rubber (SBR) or Neoprene.
Otros tipos de adhesivos: epoxi (resina epoxi más endurecedor), siliconas, fenólicas, poliimidas, plastisoles (PVC modificados), poliéster, polivinil acetato y poliacrilatos, acrilatos y metacrilatos, ciano acrilatos, fenólicas. Other types of adhesives: epoxy (epoxy resin plus hardener), silicones, phenolic, polyimides, plastisols (modified PVC), polyester, polyvinyl acetate and polyacrylates, acrylates and methacrylates, cyano acrylates, phenolic.
- Adhesivos naturales: pegatinas de colágeno, almidones, cafeína, resinas (colofonia) y gomas naturales (laca, arábiga). - Natural adhesives: collagen, starch, caffeine, resin (rosin) and natural rubber (lacquer, arabic) stickers.
Tal como se ha referido anteriormente se prevé que algunos biocidas no se microencapsulen, y por lo tanto, únicamente se impregnen o embeban sobre el propio cuerpo del calzado, sin necesidad de miroencapsulación. As mentioned above, some biocides are not expected to microencapsulate, and therefore, they are only impregnated or embedded in the body of the footwear itself, without the need for miroencapsulation.
Por otra parte, existe la posibilidad de reactivar el compuesto biocida impregnado sobre el calzado, con el fin de perpetuar el efecto repelente y/o biocida sobre el calzado, especialmente en aquellos modelos de calzado de "gama alta", tales como zapatos especializados, zapatos de montaña, botas militares, etc. On the other hand, there is the possibility of reactivating the impregnated biocidal compound on footwear, in order to perpetuate the repellent and / or biocidal effect on footwear, especially in those "high-end" footwear models, such as specialized shoes, mountain shoes, military boots, etc.
Cabe señalar que el calzado de la invención no solo sea una chancla, como se muestra en las figuras, sino que puede ser cualquier tipo de calzado. It should be noted that the footwear of the invention is not only a flip flop, as shown in the figures, but can be any type of footwear.
