Description
SOLID DETERGENT COMPOSITIONS
FIELD OF THE INVENTION
The invention relates to solid detergent compositions comprising aluminosilicate-type builder and surfactants comprised of two or more components, which have improved cleaning performance, and improved laundering and reduced residue formation on fabrics .
BACKGROUND OF THE INVENTION
All detergents on the market contain surfactants and builders. One of the detergency builders most commonly used in phosphate-free detergents are aluminosilicates. These are economic buffers, which have the added benefit that they are easy to process. In fact, these are useful processing aids because they are very good structure formers, binders or vehicle materials for other detergent ingredients. Therefore, most detergents comprise a base powder, prepared by spray drying an aluminosilicate suspension and surfactant or by agglomeration of aluminosilicate and surfactant. In addition, aluminosilicates are
useful as dusting agents, to reduce the stickiness or tendency to cake the product. A problem encountered with these detergents containing an aluminosilicate-based builder system is that they tend to cause residues on the fabric. These residues contain detergent products that are trapped in the fabrics and / or are insoluble in water. These are perceived by consumers as forming spots on the fabric. Another problem encountered with, in particular, solid detergents, is their tendency to form gels after coming into contact with water. This leads to a low supply of the product from a dispenser drawer or from a dispensing device, and also to a low dissolution of the product in the wash water. This results in the accumulation of debris in the drawer, in the dispensing device, in the washing machine and on the fabrics, which can be perceived as stains on the fabric. It has been discovered that surfactants in particular form gels after coming into contact with water. The inventors have discovered surprisingly that this particular problem arises when the surfactants and the aluminosilicates in the detergent are in close contact with one another, for example when they are in the detergent in an intimate mixture. This is the case, for example, in most known and used base powders, which are agglomerates or spray-dried powders. The inventors
they have now discovered that not only the problem of waste formation but also the problem of gelation or dissolution or dispensing problem arise mainly in most known products, when almost all surfactants and aluminosilicates are intimately mixed one with another. It has been found that when the degree of intimate mixing is reduced or even completely avoided, those problems are reduced or even completely solved. Therefore, the inventors have found a solution that still allows the incorporation of aluminosilicates and surfactants into the detergents, but in a different form: The invention provides detergents comprising at least two components comprising surfactants and aluminosilicate in such a way that a limited degree of intimate mixing occurs. The detergents of the invention have a reduced formation of residues in the fabric, in particular of insoluble detergent ingredients, of gelling, an improved dispensing and dissolution. It has been found that these benefits are obtained by any conventional way to introduce detergents to washing, including the use of a dispenser drawer, a dispensing device or by the addition of detergent in the wash prior to the addition of the wash load or the addition of the detergent on top of the washing load. The compositions may comprise an effervescence system to further assist in the dispensing or dissolution or
foam formation.
BRIEF DESCRIPTION OF THE INVENTION
The invention provides a detergent composition comprising an aluminosilicate type builder and an anionic surfactant and comprising (n) components (i), where n is at least 2, whereby the level of aluminosilicate builder in said components together is at least 5% by weight of the composition and the level of the anionic surfactant in said components together is at least 5% by weight of the composition and thereby the degree of mixing (M ) of the anionic surfactant and the aluminosilicate builder is from 0 to 0.7, where M is
s is the fraction of the anionic surfactant of the composition comprised in component (i); ? is the fraction of the anionic surfactant of the composition comprised in component (i). The composition in particular is in granulated form, in the form of an extruded material, marumerates or pastilles, or in the form of a tablet. The invention also relates to the use in a composition
detergent of at least two components comprising together an aluminosilicate at a level of at least 5% by weight of the composition and an anionic surfactant at a level of at least 5% of the composition or mixtures thereof, with which the mixing degree (M) of the anionic surfactant and the aluminosilicate type builder is from 0 to 0.7 to improve the detergent supply to the wash water, M being as defined above. The detergent compositions have an improved supply to the wash water. For the purpose of the invention, this means that the compositions provide a reduction of residues in the fabrics, in particular of water-insoluble detergent ingredients such as aluminosilicate, an improvement in the dispensing of the detergent composition, an improvement in the dissolution of detergent, a reduction in the gelling of the detergent and / or a reduction of the formation of detergent lumps on the fabrics and for compositions containing bleach, a reduced risk to the fabric.
DETAILED DESCRIPTION OF THE INVENTION
The detergent composition of the present invention comprises at least two components comprising an anionic surfactant or an aluminosilicate or mixtures thereof, whereby mixtures of aluminosilicate and the surfactant are present in one or more
of the components, the degree of mixing M is less than 0.7, as defined by the formula. In this way, each component comprises part or all of the aluminosilicate, all or a part of the anionic surfactant or mixtures thereof, with the proviso that M is from 0 to 0.7. The components of the detergent composition of the invention each comprise at least two ingredients, including the anionic surfactant and / or the aluminosilicate, which are intimately mixed. For the purpose of the invention, this means that the two or more ingredients of the component are divided substantially homogeneously into the component. Preferably, a component is such that when it comprises an anionic surfactant, the level of the anionic surfactant is less than 95%, preferably less than 85% or even less than 80% by weight of the component, whereby it could be preferring that the level of the anionic surfactant be at least 5%, preferably at least 10%, more preferred at least 20% or even more preferred at least 30% or more preferred still 35% by weight of the component. Preferably, a component is such that when it comprises an aluminosilicate, the level of the aluminosilicate is less than 95%, preferably less than 85% or even less than 80% by weight of the component, with which it may be preferred that the level of the aluminosilicate is at least 5%, preferably at least 10% by weight of the component.
It should be understood that the detergent composition of the present invention could also comprise additional intimate mixtures that are free of anionic surfactant and aluminosilicate free. In addition, the detergent composition could comprise additional ingredients that are not intimately mixed with another ingredient and therefore are not comprised in a component of the composition, as defined in the present invention. For example, the composition could comprise a detergent ingredient sprinkled on the components thereof or dry aggregates to the components of the present invention. The components together comprise the luminosilicate-type builder at a level of at least 5% by weight of the composition and the anionic surfactant at a level of at least 5% by weight of the composition. Preferably, the components comprise aluminosilicate at a level of at least 7%, or more preferred at least 10% or even 15% by weight of the composition. Depending on the precise formulation of the composition and the conditions of use, the compositions of the invention may even comprise higher levels of aluminosilicate, such as more than 20% or even more than 25%, and still provide an improved supply of the detergent to the wash. Preferably at least 7% or more preferred at least
10%, or even at least 12% by weight of the anionic surfactant composition is present in the components. Depending on the precise formulation of the composition and the conditions of use, it could be
prefer to have anionic surfactant levels of 18% by weight of the composition or higher. It may be preferred that the detergent composition comprises additional dry-added aluminosilicate, in particular to sprinkle the detergent components to reduce the risk of cake formation and / or to provide whiteness to the product. Preferably, M is less than 0.65, or even less than 0.45 or even 0.4 or 0.35. It could be preferred that M is 0, and that in this way no components are present in the detergent composition comprising both anionic surfactant and anionic surfactant. Whether or not this is preferred will depend on the levels of aluminosilicate and anionic surfactant in the detergent, or on the other ingredients present in the formulation and the amount of components present therein. The components of the present invention are preferably particles, having a particle size of at least 50 microns, more preferred the particles have a weight average particle size of more than 150 or more than 250 microns or even more than 350 microns, as measured by sieving the composition on sieves of different mesh size, and by calculating the fraction remaining in the sieve and the fraction passing through the sieve. . It may be preferred that at least one component be made by a spray drying process, as is known in the art, and at least one component be prepared by
an agglomeration process, as is known in the art. Preferably, the density of the components ranges from 250 g / liter to 1500 g / liter, more preferred at least one of the components, preferably all components, have a density of 400 g / l up to 1200 g / liter, more preferred from 500 g / liter to 900 g / liter. A rather preferred additional ingredient of the detergent compositions of the present invention could be an oxygenated bleach, preferably containing a source of hydrogen peroxide, preferably a perhydrogenated compound and a bleach activator, described later in the present invention. It has been found that improved delivery of the product to the wash results in an improved supply of the bleaching system of the present invention, which reduces the risk of bleach deposition on the fabric and the risk of damage to the fabric in patches. Another preferred additional ingredient is one or more additional builders materials, such as one or more carboxylic, monomeric, oligomeric or polymeric detergency builders and / or a stratified crystalline silicate type builder material, described later in the present invention. In addition, depending on the use of the composition and the specific formulation, the detergent composition could be substantially free of sprayed nonionic alkoxylated alcohol surfactants, which have been found to cause problems of
gelation, or dispensing or dissolving. It may then be preferred that the composition comprises other nonionic surfactants, preferably nonionic surfactants which are solid at room temperature. A further advantage could be that the omission of sprinkled nonionic alkoxylated alcohols allows the reduction or omission of pulverized materials normally required to sprinkle detergent particles containing these liquid nonionic surfactants, such as fine aluminosilicates. This not only reduces the complexity of the process, but also reduces the degree of mixing or contact of the surfactants. In addition, the inventors have discovered that in some embodiments of the invention it may be beneficial to reduce the degree of mixing between the aluminosilicate and one or more of the organic polymeric compounds, when present, for example flocculation polymers and polycarboxylate-type polymers. , as described in the present invention. The degree of mixing of the aluminosilicate and one or more of those polymers can be determined by the above formula, in which s would indicate the weight fraction of the specific polymer in a certain component. It has been found that this could reduce the formation of residues in the fabrics, in particular of water-insoluble components, such as aluminosilicate. It could also be useful that in some embodiments of the invention, the degree of mixing between the amorphous silicate and an anionic surfactant is reduced, when an amorphous silicate is present, in
In particular in mixtures containing anionic surfactant which will be dried by spray drying, it could be beneficial to reduce the amount of silicate present, for example to levels less than 3% by weight of the mixture, or even less than 2%, or even less than 1% or even 0% by weight of the mixture.
