Description
[0001] A presente invenção refere-se a partículas de distribuição de agente de benefício (tal como fragrância) e composições (tais como composição de tratamento para a lavagem de roupas) que as compreende.[0001] The present invention relates to benefit agent delivery particles (such as fragrance) and compositions (such as laundry treatment composition) comprising them.
[0002] Na composição de tratamento para a lavagem de roupas, tais como detergentes para a lavagem de roupas, a fragrância sentida pelos consumidores é um dos atributos mais importantes. A distribuição eficiente das fragrâncias corretas ao tecido durante o processo de lavagem de roupas e a liberação daquela fragrância em momentos essenciais do consumidor é crucial para a distribuição de roupa limpa e fresca.[0002] In laundry treatment composition, such as laundry detergents, the fragrance felt by consumers is one of the most important attributes. Efficiently delivering the correct fragrances to fabric during the laundry process and releasing that fragrance at key consumer moments is crucial to delivering clean, fresh laundry.
[0003] A distribuição de fragrância em momentos essenciais é uma tarefa difícil visto que detergentes para a lavagem de roupas são usualmente projetados para carregar materiais oleosos ou sólidos particulados para longe do tecido lavado. As fragrâncias, no entanto, também são tipicamente materiais oleosos.[0003] Fragrance distribution at essential times is a difficult task as laundry detergents are usually designed to carry oily materials or particulate solids away from the washed fabric. Fragrances, however, are also typically oily materials.
[0004] O encapsulamento da fragrância permite a deposição melhorada da fragrância no tecido, bem como o retardo da liberação da fragrância quando a roupa do consumidor está sendo usada.[0004] Fragrance encapsulation allows for improved deposition of the fragrance on the fabric, as well as delaying the release of the fragrance when the consumer's clothing is being worn.
[0005] No entanto, outro momento importante para o consumidor é quando a roupa está na fase “úmida”, que se estende desde quando as roupas estão sendo retiradas da máquina de lavar até quando elas estão quase secas. Há uma necessidade de uma composição que permita uma boa experiência de fragrância durante esta fase sem comprometer significativamente o desempenho da fragrância em outros estágios, tais como na composição acondicionada antes do uso e quando as roupas lavadas estão secas.[0005] However, another important moment for the consumer is when the clothes are in the “wet” phase, which extends from when the clothes are being removed from the washing machine to when they are almost dry. There is a need for a composition that allows for a good fragrance experience during this phase without significantly compromising the performance of the fragrance at other stages, such as in the composition conditioned before use and when washed clothes are dry.
[0006] A presente invenção aborda este problema.[0006] The present invention addresses this problem.
[0007] A invenção provê uma partícula de distribuição de agente de benefício tendo uma estrutura do tipo núcleo-casca em que uma casca porosa de material polimérico aprisiona um núcleo contendo o agente de benefício; em que os poros na casca são pelo menos parcialmente obstruídos por um revestimento removível por lavagem provido na superfície externa da casca; e caracterizada pelo revestimento removível por lavagem ser formado a partir de partículas depositadas de um complexo de um tensoativo catiônico e um tensoativo aniônico.[0007] The invention provides a benefit agent delivery particle having a core-shell structure in which a porous shell of polymeric material entraps a core containing the benefit agent; wherein the pores in the shell are at least partially obstructed by a washable liner provided on the outer surface of the shell; and characterized in that the washable coating is formed from particles deposited from a complex of a cationic surfactant and an anionic surfactant.
[0008] A invenção também provê uma composição de tratamento para a lavagem de roupas compreendendo uma partícula de distribuição de agente de benefício conforme definido acima.[0008] The invention also provides a laundry treatment composition comprising a benefit agent delivery particle as defined above.
[0009] O núcleo da partícula de distribuição de agente de benefício da invenção é tipicamente formado em uma região interna da partícula e provê um dissipador para o agente de benefício. A casca geralmente protege o agente de benefício contra o ambiente externo e regula o fluxo do agente de benefício para dentro e para fora do núcleo.[0009] The core of the benefit agent delivery particle of the invention is typically formed in an internal region of the particle and provides a dissipator for the benefit agent. The shell generally protects the benefit agent from the external environment and regulates the flow of the benefit agent into and out of the core.
[0010] Na partícula de distribuição de agente de benefício da invenção, a presença do revestimento removível por lavagem serve para reduzir o vazamento do agente de benefício aprisionado através dos poros na casca. A remoção do revestimento durante uma operação de lavagem facilita a liberação do agente de benefício aprisionado.[0010] In the benefit agent delivery particle of the invention, the presence of the washable coating serves to reduce leakage of the trapped benefit agent through the pores in the shell. Removing the coating during a washing operation facilitates the release of the trapped beneficial agent.
[0011] O termo “operação de lavagem” como usado aqui geralmente denota um método de lavagem do tecido usando uma composição de tratamento para a lavagem de roupas de acordo com a invenção.[0011] The term “washing operation” as used here generally denotes a method of washing fabric using a treatment composition for washing clothes according to the invention.
[0012] O Revestimento Removível Por Lavagem É Formado De Partículas Depositadas De Um Complexo De Um Tensoativo Catiônico E Um Tensoativo aniônico.[0012] The washable coating is formed from deposited particles of a complex of a cationic surfactant and an anionic surfactant.
[0013] Preferivelmente, o complexo tem uma solubilidade em água destilada (a 25 °C e à pressão atmosférica) menor que cerca de 10 mg/L, preferivelmente menor que cerca de 1 mg/L, para impedir o revestimento de ser removido muito rapidamente na lavagem.[0013] Preferably, the complex has a solubility in distilled water (at 25°C and atmospheric pressure) of less than about 10 mg/L, preferably less than about 1 mg/L, to prevent the coating from being removed too much. quickly in the wash.
[0014] Em um processo preferido usado para preparar uma partícula de distribuição de agente de benefício da invenção, o tensoativo catiônico é primeiro misturado com uma pasta fluida aquosa de partículas pré-formadas tendo uma estrutura do tipo núcleo-casca em que uma casca porosa de material polimérico circunda um núcleo contendo o agente de benefício (a seguir denominado “partículas do tipo núcleo-casca pré-formadas”). O tensoativo catiônico se deposita sobre a superfície externa da casca das partículas do tipo núcleo-casca pré-formadas. O tensoativo aniônico é, então, adicionado à mistura de partículas de forma que ele forme um complexo com o tensoativo catiônico depositado na superfície da casca exterior das partículas. As cabeças carregadas dos respectivos tensoativos são neutralizadas durante a complexação.[0014] In a preferred process used to prepare a beneficial agent delivery particle of the invention, the cationic surfactant is first mixed with an aqueous slurry of preformed particles having a core-shell type structure in which a porous shell of polymeric material surrounds a core containing the beneficial agent (hereinafter referred to as “preformed core-shell particles”). The cationic surfactant is deposited on the outer surface of the shell of preformed core-shell particles. The anionic surfactant is then added to the particle mixture so that it forms a complex with the cationic surfactant deposited on the surface of the outer shell of the particles. The charged heads of the respective surfactants are neutralized during complexation.
[0015] Os tensoativos aniônicos e tensoativos catiônicos para o uso na formação do complexo geralmente têm pesos moleculares de cerca de 1000 ou abaixo e solubilidades em água destilada (a 25 °C e à pressão atmosférica) de pelo menos cerca de 10 mg/L, preferivelmente pelo menos cerca de 100 mg/L.[0015] Anionic surfactants and cationic surfactants for use in complex formation generally have molecular weights of about 1000 or below and solubilities in distilled water (at 25 °C and atmospheric pressure) of at least about 10 mg/L , preferably at least about 100 mg/L.
[0016] Os tensoativos catiônicos adequados para o uso na formação do complexo podem ser selecionados de compostos de monoamônio quaternário de cadeia longa da fórmula geral (I): R1R2R3R4N+X- (I) onde R1 é selecionado entre cadeias de alquila ou alquenila lineares ou ramificadas contendo de 6 a 24 átomos de carbono e 0 ou 1 ligação dupla, R2, R3 e R4 são, cada um, independentemente selecionados entre grupos alquila C1 a C3 e grupos (CnH2nO)xH nos quais n é 2 ou 3 e x é de 1 a cerca de 3), e X é um ânion selecionado entre cloreto, brometo, iodeto, nitrato, sulfato, metilsulfato, etilsulfato, acetato e fosfato.[0016] Cationic surfactants suitable for use in complex formation can be selected from long-chain quaternary monoammonium compounds of general formula (I): R1R2R3R4N+X- (I) where R1 is selected from linear alkyl or alkenyl chains or branched containing 6 to 24 carbon atoms and 0 or 1 double bond, R2, R3 and R4 are each independently selected from C1 to C3 alkyl groups and (CnH2nO)xH groups in which n is 2 or 3 and x is from 1 to about 3), and X is an anion selected from chloride, bromide, iodide, nitrate, sulfate, methyl sulfate, ethyl sulfate, acetate and phosphate.
[0017] Preferivelmente na fórmula geral acima (I), R1 é selecionado entre cadeias de alquila saturadas lineares C16 a C22 e R2, R3 e R4 são, cada um, independentemente selecionados entre CH3 e CH2CH2OH, mais preferivelmente CH3.[0017] Preferably in the above general formula (I), R1 is selected from linear saturated alkyl chains C16 to C22 and R2, R3 and R4 are each independently selected from CH3 and CH2CH2OH, more preferably CH3.
[0018] Exemplos específicos de tensoativos catiônicos preferidos para o uso na formação do complexo incluem cloreto de cetiltrimetilamônio (CTAC), cloreto de esteariltrimetil amônio (STAC), cloreto de beheniltrimetilamônio (BTAC) e misturas destes.[0018] Specific examples of preferred cationic surfactants for use in complex formation include cetyltrimethylammonium chloride (CTAC), stearyltrimethylammonium chloride (STAC), behenyltrimethylammonium chloride (BTAC) and mixtures thereof.
[0019] Os tensoativos aniônicos adequados para uso na formação do complexo podem ser selecionados a partir de sais de sulfatos e sulfonatos orgânicos que possuem radicais alquila contendo de cerca de 8 a cerca de 22 átomos de carbono, sendo o termo “alquila” utilizado para incluir a porção alquila de radicais acila superiores. Exemplos de tais materiais incluem sulfatos de alquila, sulfatos de éter alquílico, sulfonatos de alcarila, sulfonatos de alfa- olefinas e misturas destes. Os radicais alquila contêm, preferivelmente, de 10 a 18 átomos de carbono e podem ser insaturados. Os sulfatos de éter alquílico podem conter de uma a dez unidades de óxido de etileno ou óxido de propileno por molécula e, preferivelmente, conter de uma a três unidades de óxido de etileno por molécula. O contraíon para tensoativos aniônicos é geralmente um metal alcalino tal como sódio ou potássio; ou um contraíon amoniacal tal como monoetanolamina, (MEA) dietanolamina (DEA) ou trietanolamina (TEA). Misturas de tais contraíons também podem ser empregadas.[0019] Anionic surfactants suitable for use in complex formation can be selected from salts of organic sulfates and sulfonates that have alkyl radicals containing from about 8 to about 22 carbon atoms, the term “alkyl” being used to include the alkyl portion of higher acyl radicals. Examples of such materials include alkyl sulfates, alkyl ether sulfates, alkaryl sulfonates, alpha-olefin sulfonates, and mixtures thereof. Alkyl radicals preferably contain from 10 to 18 carbon atoms and may be unsaturated. Alkyl ether sulfates may contain from one to ten ethylene oxide or propylene oxide units per molecule and, preferably, contain from one to three ethylene oxide units per molecule. The counterion for anionic surfactants is generally an alkali metal such as sodium or potassium; or an ammonia counterion such as monoethanolamine, (MEA) diethanolamine (DEA) or triethanolamine (TEA). Mixtures of such counterions can also be employed.
[0020] Os tensoativos aniônicos preferidos para uso na formação do complexo inclui sulfonatos de alquilbenzeno, particularmente sulfonatos de alquilbenzeno linear (LAS) com um comprimento de cadeia de alquila de 10 a 18 átomos de carbono. LAS comercial é uma mistura de isômeros intimamente relacionados e homólogos de cadeia de alquila, cada contendo um anel aromático sulfonado na posição “para” e anexado a uma cadeia de alquila linear em qualquer posição, exceto os carbonos terminais. A cadeia de alquila linear tipicamente tem um comprimento de cadeia de 11 a 15 átomos de carbono, com os materiais predominantes tendo um comprimento de cadeia de cerca de C12. Cada homólogo de cadeia de alquila consiste em uma mistura de todos os isômeros de sulfofenila possíveis, exceto para o isômero de 1-fenila.[0020] Preferred anionic surfactants for use in complex formation include alkylbenzene sulfonates, particularly linear alkylbenzene sulfonates (LAS) with an alkyl chain length of 10 to 18 carbon atoms. Commercial LAS is a mixture of closely related isomers and alkyl chain homologs, each containing a sulfonated aromatic ring in the “para” position and attached to a linear alkyl chain in any position except the terminal carbons. The linear alkyl chain typically has a chain length of 11 to 15 carbon atoms, with the predominant materials having a chain length of about C12. Each alkyl chain homologue consists of a mixture of all possible sulfophenyl isomers except for the 1-phenyl isomer.
[0021] Também são adequados os sulfatos de éter alquílico que têm um grupo de cadeia de alquila linear ou ramificada tendo de 10 a 18, mais preferivelmente de 12 a 14 átomos de carbono e contendo uma média de 1 a 3 unidades de OE por molécula.

[0023] As partículas do tipo núcleo-casca pré-formadas podem ser adequadamente feitas utilizando-se métodos conhecidos dos técnicos no assunto, por exemplo, coacervação, polimerização interfacial e policondensação.[0023] Preformed core-shell particles can be suitably made using methods known to those skilled in the art, for example, coacervation, interfacial polymerization and polycondensation.
[0024] O processo de coacervação envolve tipicamente o encapsulamento de um material de núcleo geralmente insolúvel em água pela precipitação de material(ais) coloidal(ais) sobre a superfície de gotículas do material. A coacervação pode ser simples, ou seja, utilizando um coloide, por exemplo, gelatina, ou complexa em que dois ou possivelmente mais coloides de carga oposta, por exemplo, gelatina e goma arábica ou gelatina e carboximetilcelulose, são utilizados sob condições de pH, temperatura e concentração cuidadosamente controladas.[0024] The coacervation process typically involves the encapsulation of a generally water-insoluble core material by precipitation of colloidal material(s) onto the surface of droplets of the material. Coacervation can be simple, i.e. using one colloid, e.g. gelatin, or complex in which two or possibly more oppositely charged colloids, e.g. gelatin and gum arabic or gelatin and carboxymethyl cellulose, are used under conditions of pH, carefully controlled temperature and concentration.
[0025] A polimerização interfacial tipicamente ocorre com a formação de uma fina dispersão de gotículas de óleo (em que as gotículas de óleo contêm o material de núcleo) em uma fase aquosa contínua. As gotículas dispersas formam o núcleo da futura partícula do tipo núcleo-casca e as dimensões das gotículas dispersas determinam diretamente o tamanho da futura partícula do tipo núcleo-casca. Os materiais de formação de casca (monômeros ou oligômeros) estão contidos tanto na fase dispersa (gotículas de óleo) quanto na fase aquosa contínua e reagem juntos na interface de fase para construir uma parede polimérica em torno das gotículas de óleo, para dessa forma encapsular as gotículas. Um exemplo de uma partícula do tipo núcleo-casca produzida por esse método tem uma casca de poliureia formado pela reação de diisocianatos ou poliisocianatos com diaminas ou poliaminas.[0025] Interfacial polymerization typically occurs with the formation of a fine dispersion of oil droplets (where the oil droplets contain the core material) in a continuous aqueous phase. The dispersed droplets form the nucleus of the future core-shell particle and the dimensions of the dispersed droplets directly determine the size of the future core-shell particle. The shell-forming materials (monomers or oligomers) are contained in both the dispersed phase (oil droplets) and the continuous aqueous phase and react together at the phase interface to build a polymeric wall around the oil droplets, thereby encapsulating the droplets. An example of a core-shell particle produced by this method has a polyurea shell formed by the reaction of diisocyanates or polyisocyanates with diamines or polyamines.
[0026] A policondensação envolve a formação de uma dispersão ou emulsão do material de núcleo em uma solução aquosa de pré-condensado de materiais poliméricos sob condições adequadas de agitação para produzir material de núcleo disperso de um tamanho de partícula desejado, e o ajuste das condições de reação para levar à condensação do pré-condensado por catálise ácida, resultando no condensado se separando da solução e circundando o material de núcleo disperso para produzir um filme coerente e as partículas desejadas. Um exemplo de uma partícula do tipo núcleo-casca produzida por este método tem uma casca de aminoplasto formada do produto de policondensação de melamina (2,4,6-triamino-1,3,5-triazina) ou ureia com formaldeído. Agentes de reticulação adequados (por exemplo, diisocianato de tolueno, divinilbenzeno, diacrilato de butanediol) também podem ser utilizados e polímeros de parede secundários também podem ser utilizados conforme adequado, por exemplo, anidridos e seus derivados, particularmente polímeros e copolímeros de anidrido maleico.[0026] Polycondensation involves forming a dispersion or emulsion of the core material in an aqueous solution of precondensate of polymeric materials under suitable stirring conditions to produce dispersed core material of a desired particle size, and adjusting the reaction conditions to lead to condensation of the precondensate by acid catalysis, resulting in the condensate separating from the solution and surrounding the dispersed core material to produce a coherent film and the desired particles. An example of a core-shell particle produced by this method has an aminoplast shell formed from the polycondensation product of melamine (2,4,6-triamino-1,3,5-triazine) or urea with formaldehyde. Suitable crosslinking agents (e.g. toluene diisocyanate, divinylbenzene, butanediol diacrylate) may also be used and secondary wall polymers may also be used as appropriate, for example anhydrides and derivatives thereof, particularly maleic anhydride polymers and copolymers.
[0027] Na partícula de distribuição de agente de benefício da invenção, a casca porosa de material polimérico é preferivelmente uma casca de aminoplasto formada do produto de policondensação de melamina com formaldeído.[0027] In the beneficial agent delivery particle of the invention, the porous shell of polymeric material is preferably an aminoplast shell formed from the polycondensation product of melamine with formaldehyde.
[0028] A casca é preferivelmente de um formato geralmente esférico; e compreenderá tipicamente no máximo 20% em peso com base no peso total da partícula de distribuição de agente de benefício.[0028] The shell is preferably generally spherical in shape; and will typically comprise a maximum of 20% by weight based on the total weight of the benefit agent delivery particle.
[0029] A partícula de distribuição de agente de benefício da invenção terá, de modo geral, um tamanho de partícula médio entre 100 nanômetros e 50 micrômetros. Partículas maiores que isso entram na faixa do visível. Exemplos de partículas na faixa de submicrômetros incluem látexes e miniemulsões com um tamanho de partícula médio variando de 100 a 600 nanômetros. As partículas do tipo núcleo-casca adequadas para o uso na invenção preferivelmente têm um tamanho médio de 0,6 a 50 micrômetros, mais preferivelmente de 2 a 30 micrômetros e com a máxima preferência de 5 a 25 micrômetros. A distribuição do tamanho de partícula pode ser estreita, ampla ou multimodal. Se necessário, as partículas conforme inicialmente produzidas podem ser filtradas ou peneiradas para dar origem a um produto de maior uniformidade de tamanho.[0029] The benefit agent delivery particle of the invention will generally have an average particle size between 100 nanometers and 50 micrometers. Particles larger than this enter the visible range. Examples of particles in the submicrometer range include latexes and miniemulsions with an average particle size ranging from 100 to 600 nanometers. Core-shell particles suitable for use in the invention preferably have an average size of 0.6 to 50 micrometers, more preferably 2 to 30 micrometers and most preferably 5 to 25 micrometers. Particle size distribution can be narrow, broad or multimodal. If necessary, the particles as initially produced may be filtered or sieved to produce a product of greater uniformity in size.
[0030] O termo “tamanho”, conforme aqui utilizado, refere-se ao diâmetro, salvo definição em contrário. Para amostras com diâmetro de partícula de não mais que 1 micrômetro, diâmetro significa o tamanho de partícula de média z medido, por exemplo, utilizando espalhamento dinâmico de luz (conforme definido na norma internacional ISO 13321) com um equipamento, por exemplo, Zetasizer NanoTM (Malvern Instruments Ltd, Reino Unido). Para amostras com diâmetro de partícula maior do que 1 micrômetro, diâmetro significa o diâmetro médio do volume aparente (D50), mensurável, por exemplo, por difração a laser (como estabelecido no padrão internacional ISO 13320) com um instrumento tal como um Mastersizer™ 2000 (Malvern Instruments Ltd, Reino Unido).[0030] The term “size”, as used herein, refers to diameter, unless otherwise defined. For samples with a particle diameter of no more than 1 micrometer, diameter means the z-average particle size measured, for example, using dynamic light scattering (as defined in the international standard ISO 13321) with equipment, for example, Zetasizer NanoTM (Malvern Instruments Ltd, United Kingdom). For samples with a particle diameter greater than 1 micrometer, diameter means the apparent volume mean diameter (D50), measurable, for example, by laser diffraction (as set out in the international standard ISO 13320) with an instrument such as a Mastersizer™ 2000 (Malvern Instruments Ltd, United Kingdom).
[0031] A partícula de distribuição de agente de benefício da invenção pode ser provida com um auxiliar de deposição na superfície da casca exterior. Os auxiliares de deposição servem para modificar as propriedades da superfície externa de casca, por exemplo, para tornar a partícula mais substantiva a um substrato desejado.[0031] The benefit agent delivery particle of the invention may be provided with a deposition aid on the surface of the outer shell. Deposition aids serve to modify the properties of the outer shell surface, for example, to make the particle more substantial to a desired substrate.

[0033] O auxiliar de deposição pode ser adequadamente provido na superfície externa de casca por meio de ligação covalente, entrelaçamento ou forte adsorção. Preferivelmente, tal auxiliar de deposição é fixado à superfície da casca exterior por meio de ligação covalente, seja diretamente ou por meio de uma espécie de ligação.[0033] The deposition aid can be suitably provided on the outer shell surface by means of covalent bonding, entanglement or strong adsorption. Preferably, such deposition aid is attached to the surface of the outer shell by means of covalent bonding, either directly or by means of some kind of bonding.

[0048] Os exudatos de ocorrência natural, por exemplo, óleos essenciais extraídos de plantas, também podem ser utilizados como componentes de fragrância na invenção. Os óleos essenciais são geralmente extraídos por processos de destilação de vapor, extração em fase sólida, prensagem a frio, extração de solvente, extração por fluido supercrítico, hidrodestilação ou destilação-extração simultâneas. Os óleos essenciais podem ser derivados de várias partes diferentes da planta, incluindo, por exemplo, as folhas, flores, raízes, botões, ramos, rizomas, cerne, casca, resina, sementes e frutos. As principais famílias de plantas das quais os óleos essenciais são extraídos incluem Asteraceae, Myrtaceae, Lauraceae, Lamiaceae, Myrtaceae, Rutaceae e Zingiberaceae. O óleo é “essencial” no sentido de que possui um aroma característico, ou essência, da planta.[0048] Naturally occurring exudates, for example, essential oils extracted from plants, can also be used as fragrance components in the invention. Essential oils are generally extracted by steam distillation, solid phase extraction, cold pressing, solvent extraction, supercritical fluid extraction, hydrodistillation, or simultaneous distillation-extraction processes. Essential oils can be derived from many different parts of the plant, including, for example, the leaves, flowers, roots, buds, branches, rhizomes, heartwood, bark, resin, seeds and fruits. The main plant families from which essential oils are extracted include Asteraceae, Myrtaceae, Lauraceae, Lamiaceae, Myrtaceae, Rutaceae, and Zingiberaceae. The oil is “essential” in the sense that it has a characteristic aroma, or essence, of the plant.
[0049] Os óleos essenciais são compreendidos pelos técnicos no assunto como misturas complexas que, de modo geral, consistem em várias dezenas ou centenas de constituintes. A maioria desses constituintes possui uma estrutura isoprenoide com 10 átomos de carbono (monoterpenos), 15 átomos de carbono (sesquiterpenos) ou 20 átomos de carbono (diterpenos). Também podem ser encontradas quantidades menores de outros constituintes, por exemplo, álcoois, aldeídos, ésteres e fenóis.[0049] Essential oils are understood by those skilled in the art as complex mixtures that, generally speaking, consist of several tens or hundreds of constituents. Most of these constituents have an isoprenoid structure with 10 carbon atoms (monoterpenes), 15 carbon atoms (sesquiterpenes) or 20 carbon atoms (diterpenes). Smaller amounts of other constituents can also be found, for example alcohols, aldehydes, esters and phenols.
[0050] Entretanto, um óleo essencial individual é geralmente considerado um ingrediente único no contexto de formulação prática de fragrância. Portanto, um óleo essencial individual pode ser considerado um componente de fragrância único para as finalidades da presente invenção.[0050] However, an individual essential oil is generally considered a single ingredient in the context of practical fragrance formulation. Therefore, an individual essential oil can be considered a single fragrance component for the purposes of the present invention.

[0052] O número de diferentes componentes de fragrância contidos na formulação de fragrância será, de modo geral, de pelo menos 4, preferivelmente pelo menos 6, mais preferivelmente pelo menos 8 e, com a máxima preferência, pelo menos 10, por exemplo, de 10 a 200 e, mais preferivelmente, de 10 a 100.[0052] The number of different fragrance components contained in the fragrance formulation will generally be at least 4, preferably at least 6, more preferably at least 8, and most preferably at least 10, e.g. from 10 to 200 and, more preferably, from 10 to 100.
[0053] Tipicamente, nenhum componente de fragrância único compreenderá mais que 70% em peso do peso total da formulação de fragrância. Preferivelmente, nenhum componente de fragrância único compreenderá mais que 60% em peso do peso total da formulação de fragrância e, mais preferivelmente, nenhum componente de fragrância único compreenderá mais que 50% em peso do peso total da formulação de fragrância.[0053] Typically, no single fragrance component will comprise more than 70% by weight of the total weight of the fragrance formulation. Preferably, no single fragrance component will comprise more than 60% by weight of the total weight of the fragrance formulation and, more preferably, no single fragrance component will comprise more than 50% by weight of the total weight of the fragrance formulation.
[0054] O termo “formulação de fragrância”, no contexto da presente invenção, denota os componentes de fragrância conforme definidos acima, mais quaisquer excipientes opcionais. Excipientes podem ser incluídos nas formulações de fragrância para várias finalidades, por exemplo, como solventes para componentes insolúveis ou pouco solúveis, como diluentes para os componentes mais potentes ou para controlar a pressão de vapor e as características de evaporação da formulação de fragrância. Os excipientes podem ter muitas das características de componentes de fragrância, porém não possuem fortes odores em seu interior. Consequentemente, os excipientes podem ser distinguidos dos componentes de fragrância uma vez que podem ser adicionados às formulações de fragrância em altas proporções, por exemplo, 30% ou mesmo 50% em peso do peso total da formulação de fragrância sem alterar significativamente a qualidade de odor da formulação de fragrância. Alguns exemplos de excipientes adequados incluem etanol, isopropanol, éter monoetílico de dietilenoglicol, dipropilenoglicol, ftalato de dietila e citrato de trietila. Misturas de quaisquer dos materiais descritos acima também podem ser adequadas.[0054] The term “fragrance formulation”, in the context of the present invention, denotes the fragrance components as defined above, plus any optional excipients. Excipients can be included in fragrance formulations for various purposes, for example, as solvents for insoluble or poorly soluble components, as diluents for more potent components, or to control the vapor pressure and evaporation characteristics of the fragrance formulation. Excipients can have many of the characteristics of fragrance components, but do not have strong odors within them. Consequently, excipients can be distinguished from fragrance components since they can be added to fragrance formulations in high proportions, e.g. 30% or even 50% by weight of the total weight of the fragrance formulation without significantly altering the odor quality. of fragrance formulation. Some examples of suitable excipients include ethanol, isopropanol, diethylene glycol monoethyl ether, dipropylene glycol, diethyl phthalate and triethyl citrate. Mixtures of any of the materials described above may also be suitable.

A formulação de fragrância tipicamente compreenderá de cerca de 10 a cerca de 60% e preferivelmente de cerca de 20 a cerca de 40% em peso com base no peso total da partícula de distribuição de agente de benefício. A quantidade de formulação de fragrância pode ser medida tomando-se uma pasta fluida das partículas de distribuição de agente de benefício, extraindo-se em etanol e medindo-se por cromatografia líquida.[0056] The content of fragrance components preferably ranges from 50 to 100%, more preferably from 60 to 100% and, most preferably, from 75 to 100% by weight based on the total weight of the fragrance formulation; with one or more excipients (as described above) balancing the fragrance formulation as needed. The fragrance formulation will typically comprise from about 10 to about 60% and preferably from about 20 to about 40% by weight based on the total weight of the benefit agent delivery particle. The amount of fragrance formulation can be measured by taking a slurry of the benefit agent delivery particles, extracting it into ethanol and measuring by liquid chromatography.

[0058] Em uma típica composição de tratamento para a lavagem de roupas de acordo com a invenção, o nível de partículas de distribuição de agente de benefício variará, de modo geral, de 0,01 a 10%, preferivelmente de 0,1 a 5%, mais preferivelmente de 0,3 a 3% (em peso com base no peso total da composição).[0058] In a typical laundry treatment composition according to the invention, the level of beneficial agent delivery particles will generally vary from 0.01 to 10%, preferably from 0.1 to 5%, more preferably 0.3 to 3% (by weight based on the total weight of the composition).
[0059] As partículas de distribuição de agente de benefício como descrito acima podem ser preparadas separadamente e então combinadas com outros ingredientes para formar a composição de tratamento final para a lavagem de roupas.[0059] The benefit agent delivery particles as described above can be prepared separately and then combined with other ingredients to form the final treatment composition for washing clothes.
[0060] As partículas de distribuição de agente de benefício também podem ser formadas in situ durante a preparação de, por exemplo, um detergente líquido para a lavagem de roupas incluindo tensoativo aniônico. Em um processo típico, o tensoativo catiônico é primeiro depositado sobre a superfície externa da casca das partículas do tipo núcleo-casca pré-formadas. A mistura de partículas é então combinada com ingredientes detergentes líquidos para a lavagem de roupas incluindo tensoativo aniônico (como é ainda descrito abaixo). O tensoativo aniônico dos ingredientes detergentes líquidos para a lavagem de roupas então forma um complexo com o tensoativo catiônico depositado na superfície da casca exterior das partículas. As cabeças carregadas dos respectivos tensoativos são neutralizadas durante a complexação. Se desejado, outros ingredientes podem ser adicionados à mistura para formar o detergente líquido final para a lavagem de roupas.[0060] Benefit agent delivery particles can also be formed in situ during the preparation of, for example, a liquid laundry detergent including anionic surfactant. In a typical process, the cationic surfactant is first deposited onto the outer surface of the shell of preformed core-shell particles. The particle mixture is then combined with liquid laundry detergent ingredients including anionic surfactant (as further described below). The anionic surfactant in liquid laundry detergent ingredients then forms a complex with the cationic surfactant deposited on the surface of the outer shell of the particles. The charged heads of the respective surfactants are neutralized during complexation. If desired, other ingredients can be added to the mixture to form the final liquid laundry detergent.
[0061] Uma composição de tratamento para a lavagem de roupas de acordo com a invenção está preferivelmente na forma líquida.[0061] A treatment composition for washing clothes according to the invention is preferably in liquid form.
[0062] O termo “líquido(a)”, no contexto da presente invenção, denota que uma fase contínua ou parte predominante da composição é líquida e que a composição é fluível a 15 °C e acima. Consequentemente, o termo “líquido(a)” pode abranger emulsões, suspensões e composições tendo consistência fluível, porém mais rígida, conhecida como géis ou pastas. A viscosidade da composição pode adequadamente variar de cerca de 200 a cerca de 10.000 mPa.s a 25 °C a uma taxa de cisalhamento de 21 s-1. Essa taxa de cisalhamento é a taxa de cisalhamento que é geralmente exercida sobre o líquido quando despejado de uma garrafa. As composições líquidas despejáveis têm, de modo geral, uma viscosidade de 200 a 2.500 mPa.s, preferivelmente de 200 a 1500 mPa.s.[0062] The term “liquid”, in the context of the present invention, denotes that a continuous phase or predominant part of the composition is liquid and that the composition is flowable at 15 °C and above. Consequently, the term “liquid” can encompass emulsions, suspensions and compositions having a flowable but more rigid consistency, known as gels or pastes. The viscosity of the composition may suitably range from about 200 to about 10,000 mPa.s at 25°C at a shear rate of 21 s-1. This shear rate is the rate of shear that is generally exerted on liquid when poured from a bottle. Pourable liquid compositions generally have a viscosity of 200 to 2500 mPa.s, preferably 200 to 1500 mPa.s.
[0063] As composições líquidas que são géis despejáveis têm, de modo geral, uma viscosidade de 1.500 mPa.s a 6.000 mPa.s, preferivelmente de 1.500 mPa.s a 2.000 mPa.s.[0063] Liquid compositions that are pourable gels generally have a viscosity of 1,500 mPa.s to 6,000 mPa.s, preferably 1,500 mPa.s to 2,000 mPa.s.

[0075] Tensoativos não iônicos para uso na invenção são tipicamente compostos de polioxialquileno, isto é, o produto de reação de óxidos de alquileno (sutais como óxido de etileno ou óxido de propileno ou misturas destes) com moléculas de partida tendo um grupo hidrofóbico e um átomo de hidrogênio reativo que é reativo com o óxido de alquileno. Tais moléculas de partida incluem álcoois, ácidos, amidas ou alquil fenóis. Onde a molécula de partida é um álcool, o produto de reação é conhecido como alcoxilato de álcool. Os compostos de polioxialquileno podem ter uma variedade de estruturas de bloco e hetéricas (aleatórias).

[0122] Um detergente líquido para a lavagem de roupas de acordo com a invenção também pode ter sua reologia modificada pelo uso de um ou mais estruturantes externos que formam uma rede estruturante dentro da composição. Exemplos desses materiais incluem óleo de rícino hidrogenado, celulose microfibrosa e fibra de polpa cítrica. A presença de um estruturante externo pode prover reologia de pseudoplasticidade e, também, pode permitir que materiais, como encapsulados e indicadores visuais, sejam estavelmente suspensos no líquido.[0122] A liquid detergent for washing clothes according to the invention can also have its rheology modified by the use of one or more external structuring agents that form a structuring network within the composition. Examples of these materials include hydrogenated castor oil, microfibrous cellulose, and citrus pulp fiber. The presence of an external structuring agent can provide pseudoplasticity rheology and can also allow materials, such as encapsulates and visual indicators, to be stably suspended in the liquid.
[0123] Um detergente para a lavagem de roupas de acordo com a invenção pode compreender uma quantidade eficaz de uma ou mais enzimas selecionadas do grupo que compreende pectato liase, protease, amilase, celulase, lipase, mananase e misturas destas.

[0125] Uma composição de tratamento para a lavagem de roupas da invenção pode conter outros componentes opcionais para intensificar o desempenho e/ou a aceitabilidade pelo consumidor. Exemplos de tais ingredientes incluem agentes reforçadores de espuma, conservantes (por exemplo, bactericidas), antioxidantes, protetores solares, agentes anticorrosão, colorantes, perolizantes e/ou opacificadores e corante para sombreamento. Cada um destes ingredientes estará presente em uma quantidade eficaz para realizar este propósito. De modo geral, esses componentes opcionais são incluídos individualmente em uma quantidade de até 5% (em peso com base no peso total da composição).[0125] A laundry treatment composition of the invention may contain other optional components to enhance performance and/or consumer acceptability. Examples of such ingredients include foam reinforcing agents, preservatives (e.g., bactericides), antioxidants, sunscreens, anticorrosive agents, colorants, pearlizers and/or opacifiers, and shading dye. Each of these ingredients will be present in an effective amount to accomplish this purpose. Generally speaking, these optional components are included individually in an amount of up to 5% (by weight based on the total weight of the composition).
[0126] Uma composição de tratamento para a lavagem de roupas da invenção pode ser embalada como doses unitárias em filme polimérico solúvel na água de lavagem. Alternativamente, uma composição da invenção pode ser fornecida em embalagens plásticas de múltiplas doses com um fecho superior ou inferior. Um medidor de dose pode ser fornecido com a embalagem pack tanto como parte da tampa ou como um sistema integrado.[0126] A laundry treatment composition of the invention can be packaged as unit doses in wash water-soluble polymeric film. Alternatively, a composition of the invention may be supplied in plastic multi-dose packaging with a top or bottom closure. A dose meter can be supplied with the pack packaging either as part of the cap or as an integrated system.
[0127] Um método de tratamento de tecido utilizando um detergente para a lavagem de roupas de acordo com a invenção geralmente envolverá a diluição da dose de detergente para obter um líquido de lavagem e a lavagem de tecidos com o líquido de lavagem assim formado. O método de lavagem do tecido pode ser realizado adequadamente em uma máquina de lavar automática ou pode ser realizado a mão.[0127] A method of treating fabric using a detergent for washing clothes according to the invention will generally involve diluting the dose of detergent to obtain a washing liquid and washing fabrics with the washing liquid thus formed. The method of washing the fabric can be carried out properly in an automatic washing machine or can be carried out by hand.
[0128] Em lavadoras de roupa automáticas, a dose de detergente é tipicamente colocada em um dispensador e, a partir dele, é inserido na máquina pela água que flui para dentro da máquina, formando assim o líquido de lavagem. Alternativamente, a dose de detergente pode ser adicionada diretamente no cesto. As dosagens para uma típica máquina de lavar com carregamento frontal (utilizando 10 a 15 litros de água para formar o líquido de lavagem) podem variar de cerca de 10 mL a cerca de 60 mL, preferivelmente de cerca de 15 a 40 mL. As dosagens para uma típica máquina de lavar com carregamento superior (utilizando de 40 a 60 litros de água para formar o líquido de lavagem) podem ser maiores, por exemplo, até cerca de 100 mL. Dosagens menores de detergente (por exemplo, 50 mL ou menos) podem ser usadas para métodos de lavagem manual (usando cerca de 1 a 10 litros de água para formar o licor de lavagem). Uma etapa subsequente de enxágue aquoso e de secagem das roupas é preferida. Qualquer entrada de água durante qualquer(quaisquer) etapa(s) opcional(ais) de enxágue não está incluída ao determinar o volume do líquido de lavagem.[0128] In automatic washing machines, the dose of detergent is typically placed in a dispenser and, from there, it is inserted into the machine by the water flowing into the machine, thus forming the washing liquid. Alternatively, the dose of detergent can be added directly to the basket. Dosages for a typical front-loading washing machine (using 10 to 15 liters of water to form the washing liquid) can range from about 10 mL to about 60 mL, preferably from about 15 to 40 mL. Dosages for a typical top-loading washing machine (using 40 to 60 liters of water to form washing liquid) can be higher, for example, up to around 100 mL. Smaller dosages of detergent (e.g., 50 mL or less) can be used for manual washing methods (using about 1 to 10 liters of water to form the wash liquor). A subsequent step of aqueous rinsing and drying of the clothes is preferred. Any water ingress during any optional rinse step(s) is not included when determining the wash liquid volume.
[0129] A etapa de secagem da roupa pode ocorrer em uma secadora automática ou ao ar livre.[0129] The laundry drying step can take place in an automatic dryer or outdoors.
[0130] A invenção será agora ainda descrita com referência aos seguintes Exemplos não limitativos.[0130] The invention will now be further described with reference to the following non-limiting Examples.
[0131] Todas as porcentagens em peso são em peso com base no peso total, salvo se especificado de outra forma. Exemplos de acordo com a invenção são indicados por um número; e os Exemplos Comparativos (não de acordo com a invenção) são indicados por uma letra.[0131] All percentages by weight are by weight based on total weight unless otherwise specified. Examples according to the invention are indicated by a number; and Comparative Examples (not in accordance with the invention) are indicated by a letter.
[0132] Partículas do tipo núcleo-casca de melamina-formaldeído foram preparadas tendo uma casca de melamina-formaldeído, um núcleo contendo uma fragrância modelo de 15 componentes, um diâmetro médio de partícula de aproximadamente 13 μm e um potencial zeta de aproximadamente -20 mV (quando medido como descrito acima). As partículas foram obtidas em uma pasta fluida aquosa tendo um teor de sólidos de cerca de 30% em peso. Um líquido para a lavagem de roupas foi preparado separadamente tendo ingredientes mostrados na Tabela 1. Tabela 1 [0132] Melamine-formaldehyde core-shell particles were prepared having a melamine-formaldehyde shell, a core containing a 15-component model fragrance, an average particle diameter of approximately 13 μm, and a zeta potential of approximately -20 mV (when measured as described above). The particles were obtained in an aqueous slurry having a solids content of about 30% by weight. A liquid for washing clothes was prepared separately having ingredients shown in Table 1. Table 1
[0133] A pasta fluida de partículas aquosas foi diluída com água para reduzir o teor de sólidos a cerca de 10% em peso. Uma formulação de acordo com a invenção (Exemplo 1) foi preparada primeiro adicionando CTAC (cloreto de cetiltrimetilamônio) à pasta fluida de partículas aquosas a 10% em peso e misturando por 30 minutos. Uma alíquota de 1 mL da pasta fluida de partículas tratadas com CTAC assim obtida foi então misturada com 9 mL do líquido para lavagem de roupa para formar a formulação do Exemplo 1. Uma formulação de controle também foi preparada pela adição de uma alíquota de 1 mL da pasta fluida de partículas aquosas a 10% em peso (não misturada com CTAC) a 9 mL do líquido para a lavagem de roupas.[0133] The aqueous particle slurry was diluted with water to reduce the solids content to about 10% by weight. A formulation according to the invention (Example 1) was prepared by first adding CTAC (cetyltrimethylammonium chloride) to the aqueous particle slurry at 10% by weight and mixing for 30 minutes. A 1 mL aliquot of the slurry of CTAC-treated particles thus obtained was then mixed with 9 mL of the laundry liquid to form the formulation of Example 1. A control formulation was also prepared by adding a 1 mL aliquot of of 10% by weight aqueous particle slurry (not mixed with CTAC) to 9 mL of laundry liquid.
[0134] Para testar o vazamento da fragrância das partículas do tipo núcleo- casca, as amostras de teste de controle 35 e formulações do Exemplo 1, respectivamente, foram colocadas em um rolo por 24 horas, seguido por centrifugação por 30 minutos a 11000 rpm. O líquido sobrenadante foi então removido e filtrado através de um filtro de 3,1 μm. 1 mL do filtrado foi então colocado em um frasco de espaço vazio de 20 mL. O espaço vazio acima do filtro foi medido após a incubação por 10 minutos a 40 °C em um amostrador automático CombiPAL. A amostragem foi realizada usando uma fibra DMS/Carboxen/DVB com um tempo de exposição de 60 segundos. A fibra foi, então, dessorvida por 5 minutas a 270 °C na entrada de um Agilent 6890 cromatógrafo gasoso. A separação foi realizada utilizando-se uma coluna capilar 30mBPX-5. A identificação de pico foi realizada usando um detector de massa inerte Agilent 5973N com a biblioteca de software/NIST apropriada. As integrações para os picos da fragrância foram somadas para dar um nível de fragrância total. Um gráfico de calibração, construído pela adição de quantidades conhecidas da fragrância livre ao líquido para a lavagem de roupas modelo, permitiu que o resultado fosse convertido em um valor percentual de vazamento. Os resultados são mostrados na Tabela 2. Tabela 2 [0134] To test fragrance leakage from core-shell particles, test samples of control 35 and formulations from Example 1, respectively, were placed on a roller for 24 hours, followed by centrifugation for 30 minutes at 11000 rpm . The supernatant liquid was then removed and filtered through a 3.1 μm filter. 1 mL of the filtrate was then placed in a 20 mL headspace vial. The void space above the filter was measured after incubation for 10 minutes at 40 °C on a CombiPAL autosampler. Sampling was performed using a DMS/Carboxen/DVB fiber with an exposure time of 60 seconds. The fiber was then desorbed for 5 minutes at 270 °C in the inlet of an Agilent 6890 gas chromatograph. Separation was performed using a 30mBPX-5 capillary column. Peak identification was performed using an Agilent 5973N inert mass detector with the appropriate software/NIST library. The integrations for the fragrance peaks were summed to give a total fragrance level. A calibration chart, constructed by adding known amounts of free fragrance to model laundry liquid, allowed the result to be converted into a percentage leakage value. The results are shown in Table 2. Table 2
[0135] As partículas no Exemplo 1 de acordo com a invenção demonstram um percentual de vazamento de fragrância significativamente menor do que as partículas de controle não revestidas quando incorporadas em um líquido para a lavagem de roupas. Quando o líquido para a lavagem de roupas é diluído em uma operação de lavagem (tipicamente 35 mL de líquido em 21 L de água) o revestimento é removido.[0135] The particles in Example 1 according to the invention demonstrate a significantly lower percentage of fragrance leakage than the uncoated control particles when incorporated into a laundry liquid. When laundry liquid is diluted in a washing operation (typically 35 mL of liquid in 21 L of water) the coating is removed.
[0136] Desta maneira, as partículas da invenção proveem uma melhoria na estabilidade da fragrância face ao vazamento no produto, enquanto proveem uma experiência de fragrância intensificada nos estágios iniciais após a lavagem.[0136] In this way, the particles of the invention provide an improvement in the stability of the fragrance against leakage into the product, while providing an intensified fragrance experience in the initial stages after washing.
