Abstract

The invention relates to a method for producing a base material used to produce masks for cleaning the skin and for applying cosmetic products to the skin. More specifically, the invention relates to the production of a base material created from water-soluble, partially-crosslinked polymers and applied either alone or combined with synthetic and/or natural cosmetic products, which, once dried on the skin, form an adhesive film that is flexible, microporous, consistent and firm. Once dried on the skin, the film generates and maintains a noticeable skin tightening effect (lifting) while also providing a medium for simultaneously applying cosmetic products that have a specific purpose or for cleaning or caring for the skin, and, owing to its consistency, it can be removed in large sections, without the inconvenience of leaving residue.

RETICULADOS Y UN METODO PARA RETICULARLOS PARCIALMENTE ANTECEDENTES DE LA INVENCIÓN RETICULATES AND A METHOD TO RETICULATE THEM PARTIALLY BACKGROUND OF THE INVENTION
La presente invención se refiere al campo del cuidado de la piel, particularmente se refiere a un proceso para elaborar mascarillas para el cuidado de la piel, utilizando como material base para prepararlas, polímeros parcialmente reticulados, los cuales, al mezclarse con productos utilizados en la práctica cosmética, forman una película que aporta continuamente tales productos a la piel y que al retirarla ayuda a la limpieza de la piel; los polímeros así reticulados y mezclados retienen su capacidad para formar películas delgadas, flexibles, adhesivas y micro porosas, que al aplicarse y secar sobre la piel son resistentes a la abrasión ligera y permiten la libre transpiración, por lo que pueden mantenerse durante varias horas sin causar incomodidad al usuario y que mientras se encuentran adheridas a la piel generan un efecto tensor, reducen el tamaño aparente de los poros, de pequeñas cavidades y de las líneas de expresión, que al retirarse desprenden las impurezas así como el vello débilmente adherido. La invención incluye un método para generar tales polímeros parcialmente reticulados.  The present invention relates to the field of skin care, particularly it relates to a process for making masks for the care of the skin, using as a base material to prepare them, partially cross-linked polymers, which, when mixed with products used in the cosmetic practice, form a film that continually brings such products to the skin and that when removed helps to cleanse the skin; the polymers thus crosslinked and mixed retain their capacity to form thin, flexible, adhesive and micro porous films, which when applied and dried on the skin are resistant to light abrasion and allow free transpiration, so they can be kept for several hours without cause discomfort to the user and that while they are attached to the skin generate a tensor effect, reduce the apparent size of the pores, small cavities and expression lines, which when removed release the impurities as well as weakly adhering hair. The invention includes a method for generating such partially crosslinked polymers.
En años recientes se han desarrollado, para el propósito del cuidado personal, una serie de productos para mejorar el aspecto de la piel, principalmente la piel del rostro. Estos productos son las denominadas mascarillas, la mayoría de las cuales consisten de películas textiles o a base de polímeros, impregnadas de formulaciones cosméticas, las cuales se aplican sobre la piel y que el usuario las conserva durante un cierto periodo de tiempo para que, al retirarlas, experimente una mejoría en el aspecto de la piel. Estas mascarillas tienen las mismas características en cuanto a que son paños impregnados de formulaciones cosméticas, los cuales se conservan sobre la piel sin ningún otro efecto, más que el de constituir un medio para mantener la piel expuesta a la formulación cosmética por un período determinado, ejemplos de este tipo de mascarillas lo constituyen las descritas en las patentes número US 20070023048A1, US20080051860A1 y EP 2783594E1.  In recent years have been developed, for the purpose of personal care, a series of products to improve the appearance of the skin, mainly the skin of the face. These products are the so-called masks, most of which consist of textile or polymer-based films, impregnated with cosmetic formulations, which are applied to the skin and which the user preserves for a certain period of time so that when they are removed , experience an improvement in the appearance of the skin. These masks have the same characteristics in that they are cloths impregnated with cosmetic formulations, which are preserved on the skin without any other effect, rather than constituting a means to maintain the skin exposed to the cosmetic formulation for a determined period, examples of this type of masks are those described in the patents number US 20070023048A1, US20080051860A1 and EP 2783594E1.
Otro tipo de mascarillas lo constituyen los productos en forma de geles, emulsiones o pastas, las cuales también tienen la función de mantener la piel expuesta a un producto cosmético por un tiempo determinado, sin un efecto adicional, más que el generado por el cosmético agregado. Other types of masks are products in the form of gels, emulsions or pastes, which also have the function of keeping the skin exposed to a cosmetic product for a certain time, without an additional effect, more than the one generated by the added cosmetic.
También, en la literatura especializada se reportan métodos de fabricación de mascarillas de belleza a base de polímeros, en“Cosmetic and Toiletry Formulations”, Segunda edición, Emest W. Flick 1992 Volumen 2, se documenta al menos una fórmula para preparar este tipo de mascarillas, sin embargo, al preparar y usar la formulación se forma una película que no tiene la suficiente consistencia para mantener a los componentes unidos una vez que se seca y al retirarla se rompe fácilmente en pequeñas partes que el usuario debe retirar como pequeñas secciones adheridas a la piel. Asi mismo, aunque se adhiere a la piel, no tiene la suficiente consistencia para ser retirada como una sola pieza ni mucho menos posee la adherencia suficiente para remover las impurezas presentes en la piel.  Also, in the specialized literature there are reported methods of manufacturing beauty masks based on polymers, in "Cosmetic and Toiletry Formulations", Second Edition, Emest W. Flick 1992 Volume 2, at least one formula is documented to prepare this type of masks, however, when preparing and using the formulation a film is formed that does not have enough consistency to keep the components together once it dries and when removed it breaks easily into small parts that the user must remove as small sections adhered To the skin. Likewise, although it adheres to the skin, it does not have enough consistency to be removed as a single piece, much less has enough adhesion to remove the impurities present on the skin.
Por otra parte, en la patente US 6419935B1 se describe un tipo de parche adhesivo que se aplica sobre la piel, el cual tiene la función de desprender impurezas de la piel, sin embargo no puede contener ia cantidad de cosméticos que regularmente contiene una mascarilla para fines cosméticos.  On the other hand, patent US 6419935B1 discloses a type of adhesive patch that is applied to the skin, which has the function of removing impurities from the skin, however it can not contain the amount of cosmetics that a mask contains on a regular basis. cosmetic purposes.
En la patente No. WO 2014077519A1 se describe la fabricación de un hidrogel como un material base para incorporarle diversos cosméticos, sin embargo contiene gran cantidad de productos químicos, comprende un complejo proceso de manufactura y el contenido de productos cosméticos que se le pueden incorporar está limitado a aproximadamente un 5 por ciento en peso, lo que hace limitada su aplicación.  Patent No. WO 2014077519A1 describes the manufacture of a hydrogel as a base material to incorporate various cosmetics, however it contains a large amount of chemicals, comprises a complex manufacturing process and the content of cosmetic products that can be incorporated into it. limited to approximately 5 percent by weight, which limits its application.
Por lo tanto, en el campo de la cosmeto logia aun existe la necesidad de contar con un material base que ayude a crear mascarillas pelables, adhesivas, que permitan que la piel transpire libremente, que tenga la suficiente consistencia para removerse fácilmente, que sean de manufactura simple y que sirvan para múltiples propósitos, como el de llevar a cabo una limpieza de la piel para eliminar impurezas, tales como la piel muerta, espinillas, vello débil y los comedones, y que simultáneamente sirva como vehículo para un aporte continuo de productos cosméticos hacia la piel, para mejorar su aspecto, a la vez que reduzca la posibilidad de reacciones alérgicas por un alto contenido de productos químicos. DESCRIPCION DE LA INVENCION Therefore, in the field of cosmeto loggia there is still the need to have a base material that helps to create peelable, adhesive masks that allow the skin to freely transpire, that has the sufficient consistency to be easily removed, that they are simple manufacture and that serve multiple purposes, such as carrying out a cleaning of the skin to remove impurities, such as dead skin, pimples, weak hair and comedones, and which simultaneously serves as a vehicle for a continuous supply of products Cosmetics to the skin, to improve its appearance, while reducing the possibility of allergic reactions by a high content of chemicals. DESCRIPTION OF THE INVENTION
En la presente invención se describe el proceso para elaborar un material base formado a partir de polímeros parcialmente reti cu lados que constituyen una base para aplicar tratamientos cosméticos y para la limpieza de la piel, que al aplicarse solos o mezclados con productos para el cuidado de la piel, tienen la capacidad de formar películas delgadas, adhesivas y micro porosas, que al aplicarse y secar sobre la piel generan un efecto tensor, reducen el aspecto de los poros, cavidades leves y de las líneas de expresión y que al retirarse desprende las impurezas y el vello débilmente adherido. El material base así creado puede mezclarse con productos cosméticos en proporciones de hasta aproximadamente el 25 por ciento en peso con relación al peso total de la mezcla para formar mascarillas con diversas propiedades cosméticas, las cuales están determinadas por los productos cosméticos agregados, pudiendo ser productos que aporten suavidad; que reduzcan las manchas de la piel; productos para humectarla; productos para reducir el tamaño de los poros o el aspecto de las líneas de expresión, productos para darte firmeza a la piel o cualquier otro producto con efectos específicos, ya que el material base objeto de esta invención, al ser un producto base agua se puede considerar como un producto inerte, que no reacciona con los productos utilizados en la práctica cosmética actual. Una ventaja que tiene es que una vez que la mascarilla ha secado sobre la piel, constituye una película que es resistente a la abrasión ligera y que no causa incomodidad al usuario, pues conserva una gran flexibilidad y permite que la piel transpire libremente, pudiendo el usuario conservarla por varias horas e incluso dormir con ésta mientras permanece aplicada sobre la piel del rostro.  In the present invention, the process for preparing a base material formed from partially retreated polymers is described, which constitute a basis for applying cosmetic treatments and for cleaning the skin, which when applied alone or mixed with products for the care of the skin, have the ability to form thin, adhesive and micro porous films, which when applied and dried on the skin generate a tensor effect, reduce the appearance of pores, slight cavities and fine lines and which when removed release the impurities and weakly adhering hair. The base material thus created can be mixed with cosmetic products in proportions of up to about 25 weight percent relative to the total weight of the mixture to form masks with various cosmetic properties, which are determined by the added cosmetic products, and can be products that provide softness; that reduce the spots of the skin; products to moisturize it; products to reduce the size of the pores or the appearance of the lines of expression, products to give firmness to the skin or any other product with specific effects, since the base material object of this invention, being a water-based product, can be consider as an inert product, which does not react with the products used in current cosmetic practice. An advantage that it has is that once the mask has dried on the skin, it constitutes a film that is resistant to light abrasion and that does not cause discomfort to the user, since it retains a great flexibility and allows the skin to freely transpire, the User keep it for several hours and even sleep with it while it remains applied on the skin of the face.
El medio para generar el material base, para elaborar las mascarillas cosméticas, objeto de esta invención, es mediante la reticulación parcial de polímeros solubles en agua; el proceso de reticulación parcial transforma a los polímeros en buenos agentes fo rimadores de películas las cuales tienen las características de que al ser aplicadas son delgadas, viscosas, muy adhesivas y que son permeables a los gases y vapores, por lo que su uso sobre la piel no ocasiona incomodidad a los usuarios, aun cuando las usen por periodos prolongados, pues permite que la piel transpire libremente. Las características del material base objeto de esta invención son las pocas etapas de fabricación involucradas, así como una mínima cantidad de productos presentes en la formulación. Por otra parte, la composición del material base incluye solo materiales bíocompatibles, lo que reduce el riesgo de reacciones alérgicas al usuario, adicional a que el material base es lavable con agua y cualquier aplicación en una zona no deseada puede limpiarse fácilmente enjuagando con agua. The means for generating the base material, for preparing the cosmetic masks, object of this invention, is through the partial cross-linking of water-soluble polymers; The process of partial cross-linking transforms the polymers into good film-forming agents which have the characteristics that when applied they are thin, viscous, very adhesive and that they are permeable to gases and vapors, so their use on the Skin does not cause discomfort to users, even when they are used for prolonged periods, because it allows the skin to breathe freely. The characteristics of the base material object of this invention are the few manufacturing stages involved, as well as a minimum amount of products present in the formulation. On the other hand, the composition of the base material includes only materials biocompatible, which reduces the risk of allergic reactions to the user, in addition to the base material is washable with water and any application in an unwanted area can be easily cleaned by rinsing with water.
El material base objeto de esta invención, en su estado base, es decir, antes de agregarle cualquier otra formulación cosmética, es un líquido viscoso, adhesivo y cristalino que tiene la capacidad de formar, por sf mismo, una película delgada. Por otra parte también permite ser combinado con prácticamente cualquier material o formulación cosmética; una vez hecha la mezcla entre el material base y el o los productos cosméticos involucrados, la mezcla se esparce sobre la piel hasta formar una película de unos pocos milímetros de espesor; después de aproximadamente 30 minutos la mezcla del material base y los productos cosméticos que forman la mascarilla se habrán secado y la película estará adherida firmemente a la piel; simultáneamente, durante el proceso de secado iniciará un proceso de tensión sobre la piel en todas direcciones, generando incluso una fuerza de tensión perpendicular a la piel, la cual es generada por el efecto de la contracción de la película durante el secado. Esta fuerza perpendicular a la piel hace que el interior de los poros sea halado suavemente hacia la superficie, lo que reduce evidentemente su aspecto.  The base material object of this invention, in its base state, that is, before adding any other cosmetic formulation, is a viscous, adhesive and crystalline liquid which has the capacity to form, by itself, a thin film. On the other hand it also allows to be combined with practically any material or cosmetic formulation; once the mixture is made between the base material and the cosmetic product (s) involved, the mixture is spread on the skin to form a film a few millimeters thick; after about 30 minutes the mixture of the base material and the cosmetics that form the mask will have dried and the film will be firmly attached to the skin; simultaneously, during the drying process will initiate a tension process on the skin in all directions, generating even a tension force perpendicular to the skin, which is generated by the effect of shrinkage of the film during drying. This force perpendicular to the skin causes the interior of the pores to be pulled gently towards the surface, which evidently reduces its appearance.
Si la Mascarilla así elaborada se conserva sobre la piel durante varias horas, por ejemplo, una noche, el efecto de alisamiento de los poros y otras cavidades será evidente al remover la mascarilla a la mañana siguiente. Este mismo efecto de alisamiento sucede con las marcas dejadas por el acné y sobre las líneas marcadas sobre la piel, así como con las líneas que se generan alrededor de la boca y a un lado de los ojos.  If the Mask thus elaborated is kept on the skin for several hours, for example, one night, the smoothing effect of the pores and other cavities will be evident when the mask is removed the next morning. This same effect of smoothing happens with the marks left by acne and on the lines marked on the skin, as well as with the lines that are generated around the mouth and on one side of the eyes.
Asimismo, como una forma de potencializar el efecto tensor de la mascarilla formada por el material base y los productos cosméticos, y como parte de esta invención, aun estando fresca y aplicada sobre la piel, se pueden colocar sobre ésta recortes de tela tejida o no tejida, de origen natural o sintético o de una fina malla de polímero, con lo cual, al secar la mascarilla, constituye una base firme que genera un punto de apoyo para que, al contraerse la película, el alisamiento de los poros y líneas de expresión sea más evidente cuando se retira.  Also, as a way to potentiate the tensor effect of the mask formed by the base material and the cosmetic products, and as part of this invention, even being fresh and applied on the skin, pieces of woven fabric or not may be placed on it. woven, of natural or synthetic origin or of a fine polymer mesh, with which, when drying the mask, it constitutes a firm base that generates a point of support so that, when the film contracts, the smoothing of the pores and lines of expression is more evident when it is removed.
Mientras el usuario mantenga la mascarilla sobre la piel, experimentará un notable efecto tensor, sin embargo, debido a que la mascarilla está constituida por un material base que forma una película micro porosa, el usuario no experimentará incomodidades por el bloqueo de la transpiración natural de la piel, ya que el material base de la mascarilla, permite que la piel transpire libremente, debido a que está formado por una red microscópica de moléculas entrelazadas entre sí que permiten el paso de los gases y vapores producto de la transpiración. While the user keeps the mask on the skin, it will experience a remarkable tensing effect, however, because the mask is constituted by a base material that forms a micro porous film, the user will not experience discomfort due to the blockage of the natural transpiration of the skin, since the base material of the mask allows the skin to freely transpire, because it is formed by a microscopic network of interlaced molecules that allow the passage of gases and vapors product of perspiration.
Las ventajas que presenta el material base objeto de la presente invención es que al mezclarse con los productos cosméticos mencionados más adelante, la película que forma la mezcla presenta una buena consistencia cuando se seca lo que le da la ventaja de poder removerse fácilmente de una sola pieza o en grandes piezas, después de un tiempo de secado de aproximadamente 20 a 30 minutos, variando el tiempo de reposo según las condiciones climáticas, y sin dejar residuos.  The advantages of the base material object of the present invention is that when mixed with the cosmetic products mentioned below, the film forming the mixture has a good consistency when dried, which gives it the advantage of being easily removed from a single product. piece or in large pieces, after a drying time of approximately 20 to 30 minutes, varying the resting time according to weather conditions, and leaving no residue.
Una ventaja sobre otras mascarillas es que el material base objeto de esta invención, después de haber sido reticulado y en su estado puro (libre de cosméticos o aditivos), puede ser mezclado por un usuario final para crear y aplicarse sus propias formulaciones cosméticas en forma de mascarillas, ya que el material base permite ser mezclado también con productos naturales, tales como infusiones o extractos concentrados de productos herbolarios, colágeno, elastina y aceites grasos, hasta en aproximadamente un 25 por ciento en peso con relación al peso total de la mezcla, lo que da al usuario final una amplia gama de aplicaciones. Esto constituye una característica importante del material base objeto de esta invención, dado que en años recientes se ha dado un crecimiento importante en el uso de producto naturales, debido precisamente a que las personas buscan opciones más naturales para el cuidado de la piel, a la vez que buscan tener menos exposición a agentes químicos.  An advantage over other masks is that the base material object of this invention, after having been crosslinked and in its pure state (free of cosmetics or additives), can be mixed by an end user to create and apply its own cosmetic formulations in the form of masks, since the base material can also be mixed with natural products, such as infusions or concentrated extracts of herbal products, collagen, elastin and fatty oils, up to approximately 25 percent by weight in relation to the total weight of the mixture , which gives the end user a wide range of applications. This constitutes an important characteristic of the base material object of this invention, given that in recent years there has been an important growth in the use of natural products, precisely because people seek more natural options for skin care, to the instead they seek to have less exposure to chemical agents.
