DESCRIPCIONDESCRIPTION
Ingredientes de rendimiento en partfculas de pelfculaPerformance ingredients in film particles
La presente invencion se refiere a composiciones detergentes granulares que comprenden una pluralidad de partfculas de pelfcula.The present invention relates to granular detergent compositions comprising a plurality of film particles.
AntecedentesBackground
Se conoce la inclusion de partfculas visualmente contrastantes en composiciones detergentes para lavar la ropa granulares. Las partfculas contrastantes pueden administrar un ingrediente funcional o pueden simplemente proporcionar una senal visual al usuario.The inclusion of visually contrasting particles in detergent compositions for washing granular clothes is known. The contrasting particles can administer a functional ingredient or can simply provide a visual signal to the user.
En el documento US 4082682, se agrega una proporcion minoritaria de partfculas de jabon alargadas de colores contrastantes a un polvo detergente. Las partfculas contrastantes comprenden un tinte y un agente de fluorescencia no sustantivos para el tejidotejido. El polvo comprende un compuesto mejorador de la detergencia. Las partfculas de jabon brindan detergencia a la composicion y reducen la formacion de espuma. Dado que las partfculas de jabon podrfan hundirse en el tejidotejido se dice que la ventaja de las partfculas es que no producen manchas en el tejidotejido con la que entran en contacto.In US 4082682, a minor proportion of elongated soap particles of contrasting colors is added to a detergent powder. The contrasting particles comprise a non-substantive dye and fluorescence agent for the woven fabric. The powder comprises a detergency builder compound. Soap particles provide detergency to the composition and reduce foam formation. Since the soap particles could sink into the woven fabric it is said that the advantage of the particles is that they do not produce stains on the woven fabric with which they come into contact.
En el documento GB2358403A se ha mezclado en seco una composicion detergente en polvo que tiene una proporcion importante de partfculas blancas o de color claro en una menor proporcion de cuerpos lamelares visualmente contrastantes de tamano de partfcula promedio significativamente mayor en al menos una dimension que el tamano de partfcula promedio de las partfculas blancas o de color claro. Los ejemplos utilizaron cuerpos de forma circular o de estrella contrastantes hechos de pelfcula polimerica soluble en agua de colores. Los cuerpos visualmente contrastantes pueden contener opcionalmente ingredientes detergentes funcionales.In GB2358403A, a powder detergent composition having an important proportion of white or light colored particles in a smaller proportion of visually contrasting lamellar bodies of significantly larger average particle size in at least one dimension than the size has been dry mixed of average particle of white or light colored particles. The examples used contrasting circular or star bodies made of colored water soluble polymeric film. The visually contrasting bodies may optionally contain functional detergent ingredients.
El documento W02006/079416 propone emplear una partfcula de pelfcula muy soluble como una senal visual. Se sugiere la posibilidad de incluir ingredientes funcionales dentro de la pelfcula, p. ej. agentes activos en superficie, perfume, antioxidante, antiespumante. Ejemplos en esta solicitud comparan polvos detergentes que contienen un 0,1 % en peso de senales visuales hechas con alcohol polivinflico con senales visuales de goma arabiga. Adecuadamente, las partfculas de pelfcula podrfan seleccionarse de modo que atraviesen un tamiz de 1400 pm, pero no uno de 500 pm.Document W02006 / 079416 proposes to employ a very soluble film particle as a visual signal. The possibility of including functional ingredients within the film is suggested, e.g. ex. surface active agents, perfume, antioxidant, antifoam. Examples in this application compare detergent powders containing 0.1% by weight of visual signals made with polyvinyl alcohol with visual arabic rubber signals. Suitably, the film particles could be selected to pass through a sieve of 1400 pm, but not one of 500 pm.
Se sabe que se agregan ingredientes sensibles a polvos para lavar la ropa como granulos fabricados separadamente. Este procedimiento puede denominarse mezclado en seco o post-dosificacion.It is known that powder-sensitive ingredients are added to wash clothes as separately manufactured granules. This procedure can be called dry mixing or post-dosing.
El documento US4176079 describe una alternativa a granulos de post-dosificacion. Se incorpora una enzima en una pelfcula soluble en agua y la pelfcula funcional asf producida se corta en cuadrados, rectangulos o bandas y se agrega a un polvo detergente. Las composiciones tfpicas de aditivo de pelfcula son 48,7 % de alcohol polivinflico y 43,8 % de tensioactivo no ionico (el resto agua y enzima). El aditivo de pelfcula funcional cortada tiene un area de superficie de 300 mm2.Document US4176079 describes an alternative to post-dosage granules. An enzyme is incorporated into a water soluble film and the functional film thus produced is cut into squares, rectangles or bands and added to a detergent powder. Typical compositions of film additive are 48.7% polyvinyl alcohol and 43.8% non-ionic surfactant (the rest water and enzyme). The cut film functional additive has a surface area of 300 mm2.
El documento US 2005/0075261 A1 se refiere a una partfcula soluble en agua y/o dispersable en agua que comprende un ingrediente activo, preferentemente una enzima, en una matriz que comprende el 20-95 % de la partfcula de un polfmero de alcohol polivinflico especificado. Los ejemplos elaboran la partfcula aplicando una accion de corte a una cinta extrudida. Esto tenderfa a elaborar una partfcula granular (esferica). Otros ingredientes activos sugeridos para su inclusion a niveles del 0,1 al 55 % incluyen: blanqueadores, activadores de blanqueo, catalizadores de blanqueo, abrillantadores y fotoblanqueadores. El tamano de partfcula oscila entre 200 pm y 2000 pm, preferentemente entre 250 pm y 800 pm. En una forma de realizacion en la que la partfcula extrudida (cilfndrica) no esta cortada puede tener hasta 20 mm de largo, pero es preferentemente de menos de 1 mm de largo y tiene una distribucion de tamano de partfculas preferido de 100 pm a 800 pm.US 2005/0075261 A1 refers to a water soluble and / or water dispersible particle comprising an active ingredient, preferably an enzyme, in a matrix comprising 20-95% of the particle of a polyvinyl alcohol polymer specified. The examples elaborate the particle by applying a cutting action to an extruded tape. This would tend to make a granular (spherical) particle. Other suggested active ingredients for inclusion at levels of 0.1 to 55% include: bleaching agents, bleaching activators, bleaching catalysts, brighteners and photobleaching agents. The particle size ranges from 200 pm to 2000 pm, preferably between 250 pm and 800 pm. In an embodiment in which the extruded (cylindrical) particle is not cut, it can be up to 20 mm long, but is preferably less than 1 mm long and has a preferred particle size distribution of 100 pm to 800 pm .
Sigue existiendo una cantidad de problemas relacionados con el uso de partfculas de pelfcula en composiciones detergentes granulares, especialmente detergentes para lavar la ropa granulados.There are still a number of problems related to the use of film particles in granular detergent compositions, especially laundry detergents.
Un problema importante es elaborar una partfcula de pelfcula de senal visual que ayude a limpiar. Sorprendentemente, los autores de la invencion han encontrado ahora nuevos beneficios de liberacion de ingredientes de beneficio especfficos a partir de una partfcula de pelfcula.An important problem is to develop a particle of visual signal film that helps to clean. Surprisingly, the authors of the invention have now found new benefits of releasing specific benefit ingredients from a film particle.

Descripcion detallada de la invencionDetailed description of the invention
Las composiciones detergentes para lavar la ropa granulares estan compuestas principalmente por tensioactivos y electrolitos. Los tensioactivos tfpicos incluyen alquilbencensulfonatos lineales, sulfatos de alcohol primario, etoxisulfatos de alcohol lineales y alcohol etoxilatos. Los electrolitos tfpicos son materiales inorganicos tales como sulfato de sodio, cloruro de sodio, tripolifosfatos de sodio, carbonato de sodio, sflices y zeolitas y materiales organicos tales como policarboxilatos y acido cftrico.The detergent compositions for washing the granular clothes are mainly composed of surfactants and electrolytes. Typical surfactants include linear alkylbenzenesulfonates, primary alcohol sulfates, linear alcohol ethoxy sulfates and alcohol ethoxylates. Typical electrolytes are inorganic materials such as sodium sulfate, sodium chloride, sodium tripolyphosphates, sodium carbonate, slices and zeolites and organic materials such as polycarboxylates and citric acid.
Para dar beneficios de lavado adicionales, pueden incluirse a niveles bajos ingredientes de beneficio, a saber agentes de fluorescencia, tintes matizadores, fotoblanqueadores, antioxidantes y catalizadores. Dichos ingredientes de beneficio son sumamente efectivos en materia de costo cuando se agregan a niveles muy bajos, tipicamente de menos del 0,1 % en peso de la composicion. Los ingredientes de beneficio usualmente se granulan y luego se post- dosifican en la composicion granular. Esto inevitablemente da como resultado altas concentraciones localizadas del ingrediente de beneficio, lo que puede causar problemas si se ponen en contacto con determinados tejidos antes de que tengan una oportunidad de disolverse o dispersarse en el licor de lavado. Este problema esta causado por la alta concentracion localizada del ingrediente de beneficio y no por el tiempo de su liberacion. El problema se produce especialmente en el caso de ingredientes de beneficio de bajo peso molecular que causan danos a los tejidos cuando estan presentes a concentraciones muy altas, especialmente si se administran desde un sustrato portador que tenga una mayor solubilidad y/o dispersibilidad que el ingrediente de beneficio.To give additional washing benefits, benefit ingredients may be included at low levels, namely fluorescence agents, tinting dyes, photobleach, antioxidants and catalysts. Such benefit ingredients are extremely cost effective when added at very low levels, typically less than 0.1% by weight of the composition. Beneficial ingredients are usually granulated and then post-dosed in the granular composition. This inevitably results in high localized concentrations of the benefit ingredient, which can cause problems if they come into contact with certain tissues before they have a chance to dissolve or disperse in the wash liquor. This problem is caused by the high localized concentration of the benefit ingredient and not by the time of its release. The problem occurs especially in the case of low molecular weight benefit ingredients that cause tissue damage when they are present at very high concentrations, especially if they are administered from a carrier substrate that has a higher solubility and / or dispersibility than the ingredient. of benefit
El encapsulado del ingrediente o ingredientes de beneficio dentro de la pelfcula polimerica soluble proporciona una solucion a este problema. La cantidad de ingrediente de beneficio en la partfcula de pelfcula es preferentemente 0,05 al 1,0 % en peso de la partfcula de pelfcula.The encapsulation of the benefit ingredient or ingredients within the soluble polymeric film provides a solution to this problem. The amount of benefit ingredient in the film particle is preferably 0.05 to 1.0% by weight of the film particle.
Las partfculas de pelfcula se vuelven convenientemente visibles por medio de un tinte no sustantivo para tejido que les da un color contrastante con respecto a los granulos que forman el resto de la composicion granulada.The film particles become conveniently visible by means of a non-substantive dye for tissue that gives them a contrasting color with respect to the granules that form the rest of the granulated composition.
Las composiciones detergentes granulares de color mas claro que las partfculas de pelfcula incluyen ventajosamente algo de agente de fluorescencia y/o tinte matizador en los granulos para dar un mayor contraste entre los granulos y las partfculas de pelfcula.Granular detergent compositions of a lighter color than the film particles advantageously include some fluorescent agent and / or tint dye in the granules to give a greater contrast between the granules and the film particles.
La composicion detergente granular es preferentemente muy alcalina cuando se disuelve en agua desionizada. Una solucion al 0,1 % a 25 °C tiene un pH > 10,5. Para lograr este pH la composicion detergente granular puede comprender ventajosamente silicato y/o carbonato.The granular detergent composition is preferably very alkaline when dissolved in deionized water. A 0.1% solution at 25 ° C has a pH> 10.5. To achieve this pH the granular detergent composition may advantageously comprise silicate and / or carbonate.
La partfcula de pelfcula esta preferentemente mas cerca de un pH neutro para proteger el o los ingredientes de beneficio que contiene. Tiene un pH comprendido entre 3 y 9, preferentemente entre 6 y 8 cuando se disuelve para formar una solucion al 0,1 % en agua desionizada.The film particle is preferably closer to a neutral pH to protect the benefit ingredient (s) it contains. It has a pH between 3 and 9, preferably between 6 and 8 when dissolved to form a 0.1% solution in deionized water.
Aunque muchos polfmeros solubles podnan ser adecuados para su inclusion en la partfcula de pelfcula, la partfcula de pelfcula comprende al menos alcohol polivimlico al 30 %. Para mejorar su solubilidad y facilitar la inclusion de los ingredientes de beneficio, las partfculas de pelfcula comprenden ademas deseablemente entre el 5 y el 50 % en peso de tensioactivo. El contenido preferido de tensioactivo de las partfculas de pelfcula es de al menos el 5 % de tensioactivo anionico, mas preferentemente un alquilsulfato.Although many soluble polymers may be suitable for inclusion in the film particle, the film particle comprises at least 30% polyvinyl alcohol. To improve their solubility and facilitate the inclusion of the benefit ingredients, the film particles also desirably comprise between 5 and 50% by weight of surfactant. The preferred surfactant content of the film particles is at least 5% anionic surfactant, more preferably an alkyl sulfate.
Ingredientes adicionales opcionales son: adjuntos para ayudar en la fabricacion de la pelfcula, por ejemplo agentes de liberacion y agua. Ademas de su efecto en el control de la humedad relativa de la pelfcula, el agua tambien ayuda en la plastificacion de la misma y regula su solubilidad.Additional optional ingredients are: adjuncts to assist in the manufacture of the film, for example release agents and water. In addition to its effect in the control of the relative humidity of the film, water also helps in plasticizing it and regulates its solubility.

Para lograr el uso mas efectivo de sus productos de lavado muchos consumidores remojan sus prendas en una solucion de composicion detergente para lavar la ropa. A menudo las prendas se ponen en agua, se rocfa la composicion detergente en la parte superior y las prendas se dejan despues entre 2 y 200 minutos. En este procedimiento, una composicion detergente para lavar la ropa granular puede no disolverse por completo y puede producirse el manchado de los tejidos de la ropa con los ingredientes de beneficio. El manchado implica la solucion incompleta de los granulos y la subsiguiente formacion de una alta concentracion localizada del ingrediente de beneficio en contacto con el tejido de las prendas, esta sobredosis muy concentrada y localizada de ingrediente de beneficio puede gelificarse despues y ello se inhibe luego de dispersion o solucion adicional. El problema es lo mas pronunciado y obvio con tintes y fotoblanqueadores donde aparecen manchas de color claro sobre el tejido de las prendas. El fenomeno reduce tambien la efectividad de los ingredientes de beneficio, porque no todo el ingrediente se hace disponible para el lavado completo.To achieve the most effective use of their washing products, many consumers soak their clothes in a solution of laundry detergent composition. Often the garments are put in water, the detergent composition is sprayed on top and the garments are left after 2 to 200 minutes. In this procedure, a detergent composition for washing the granular clothes may not dissolve completely and staining of the fabrics of the clothes with the beneficial ingredients may occur. The staining implies the incomplete solution of the granules and the subsequent formation of a high localized concentration of the benefit ingredient in contact with the fabric of the garments, this highly concentrated and localized overdose of the benefit ingredient can gel afterwards and this is inhibited after dispersion or additional solution. The problem is the most pronounced and obvious with dyes and photo whiteners where light colored spots appear on the fabric of the garments. The phenomenon also reduces the effectiveness of the beneficial ingredients, because not all the ingredient is made available for complete washing.
Este problema se supera incorporando los ingredientes de beneficio en una pelfcula de polfmero soluble que seguidamente se corta en trozos discretos que tienen area transversal baja de menos de 100 mm2. Dichas partfculas de pelfcula pueden servir tambien como senales visuales dado que tambien incluyen tintes. Su funcion como una senal visual puede incrementarse aun mas cortando las partfculas de pelfcula en la forma de una flor con petalos, o algun otro objeto natural tal. El area transversal tendrfa que ser de al menos 4 mm2. Por area transversal los autores de la invencion se refieren al area de superficie real de un lado de la partfcula plana.This problem is overcome by incorporating the benefit ingredients in a soluble polymer film which is then cut into discrete pieces that have a low transverse area of less than 100 mm2. Said film particles can also serve as visual signals since they also include dyes. Its function as a visual signal can be further increased by cutting the film particles in the form of a flower with petals, or some other such natural object. The cross-sectional area should be at least 4 mm2. By cross-sectional area the authors of the invention refer to the real surface area of one side of the flat particle.
Las partfculas de pelfcula tienen la ventaja adicional de mantener los ingredientes de beneficio a menudo sensibles, alejados del pH elevado agresivo de una composicion detergente para lavar la ropa base. Ello proporciona una senal visual clara al usuario de que esta presente el ingrediente de beneficio. Es particularmente conveniente que la partfcula de pelfcula flote cuando se anade primero a agua. Esto incrementa la visibilidad de la partfcula de pelfcula en uso y puede tambien ayudar con la reduccion del manchado u otro dano a los tejidos debido a la solucion inicial que tiene lugar en la superficie, que es probable que este lejos de la mayor parte de el tejido que se esta lavando. Para asegurar que la partfcula de pelfcula flote se prefiere que su densidad relativa sea menor que 0,8, mas preferentemente menor que 0,5 y lo mas preferentemente menor que 0,4.The film particles have the additional advantage of keeping the often sensitive benefit ingredients, away from the aggressive high pH of a detergent composition for washing the base clothes. This provides a clear visual signal to the user that the benefit ingredient is present. It is particularly convenient for the film particle to float when it is first added to water. This increases the visibility of the film particle in use and may also help with the reduction of staining or other tissue damage due to the initial solution that takes place on the surface, which is likely to be far from most of the fabric that is being washed. To ensure that the film particle floats it is preferred that its relative density be less than 0.8, more preferably less than 0.5 and most preferably less than 0.4.
El espesor de la pelfcula plana de la partfcula de pelfcula es como maximo 0,5 mm. Preferentemente es menor a 0,3 mm, lo mas preferentemente 0,2 mm. La pelfcula es de un espesor relativamente uniforme para permitir caracterfsticas de solucion predecibles. La tolerancia del espesor es como mucho de mas o menos el 20 %, preferentemente de mas o menos el 10 %.The thickness of the flat film of the film particle is at most 0.5 mm. It is preferably less than 0.3 mm, most preferably 0.2 mm. The film is of a relatively uniform thickness to allow predictable solution characteristics. The thickness tolerance is at most 20%, preferably more or less 10%.
