Description

Solid detergent compositions.

Technical field

The invention relates to compositions detergents, in particular detergent compositions for the laundry

Background of the invention

All detergents for applications laundry wash contain surfactants and additives that enhance the detergency Generally, most detergents comprise a base powder manufactured by spray drying or by granulation of detergency builder components and surfactant components, for example, by agglomeration or extrusion. The base powder is usually also subjected to stages of post-treatment as the dry addition of others detergent components in the form of particles, spraying other liquid components such as surfactants, especially non-ionic surfactants and / or subsequent lubrication stages with solid materials in the form of fine particles to reduce the caking and stickiness of solid detergents produced.

Environmental pressures have forced manufacture detergents as efficient as possible. The tendency to use smaller amounts of detergent compositions more compact, for example, with a density greater than 600 g / l or 650 g / l or more than 700 g / l or even higher, the need to ensure total performance of all components detergents in the washing medium.

However, solid detergents have a tendency to form lumps or gels in contact with water. In this case, lumps of gelled material may fall into the sump of a washing machine, where they are not subjected to any mechanical action and / or, due to their method of use in the washing machine, once in it the solid detergents do not dissolve or a poor supply of product is produced from the dispensing box of a washing machine or from another dispensing device. Therefore, the use of all detergent components is defi-
enough

The inventors have discovered that for solving this problem requires a combination of properties. This can be achieved by controlling the detergent and its process of manufacturing so that the combinations of the different detergent components, when they have been formed into particles to get the finished detergent, modify to get the maximum performance advantage for each of the components detergents This leads to good detergent compositions. solubility and minimal gelation and, therefore, at maximum supply of the detergent components to the washing medium, for example, minimizing the interaction between some components detergents and maximizing interaction between others detergent components These advantages provide a good washing performance and minimize any deterioration of the tissue due to excessive concentration of bleach.

In WO97 / 02339 it is described that achieves good solubility by providing detergent particles of a given grain structure. In EP-A-342043 separates the slow solubility surfactants of the surfactants of fast solubility

Summary of the invention

In the present invention a solid detergent composition as defined in claim 1, which comprises 10-60% by weight of a system surfactant and having a maximum residue index of 25 and a Maximum secondary waste index of 15.

The Waste Index can be calculated as next:

1 liter of deionized water is introduced into a dissolution apparatus (Erweka DT6-R, mentioned in hereinafter as the "Sotax" device) (USP 711 Dissolution). He Sotax is equipped with a perspex lid to prevent evaporation, is calibrated at a temperature of 5 ° C with the stirrer (paddle) and regulated at 21 rad / s (200 rpm). The palette has two sheets fixed on the central axis opposite each other so that the diameter Total of the palette with the two sheets is 75 mm. The palette is placed in the center of the Sotax device so that the distance between the lower end of the vane and the bottom of the apparatus solution is 25 mm. The total height of the palette sheets is 19 mm A wire basket that has walls is supplied sides and a base formed of stainless steel wire 20 mesh (850 µm), a diameter of 25 mm and a height of 41 mm. The wire basket is filled with a detergent product whose surface is flush and a non-permeable cover is used to Close the top of the wire basket. Then you Suspend the wire basket to a fixed equidistant position of the central axis of the Sotax and of the side wall at a height such that the base of the wire basket is 7 mm above the surface upper blade.

After twelve minutes the set of the wire basket of the Sotax device and the residue is passed to a previously heavy container. The transfer stage has to be quantitative; a rinse stage with deionized water is accepted in necessary case. The waste is oven dried 70-80 ° C until no more loss of weight. The weight of the dry residue is noted. Then the percentage residue of the basket in relation to the mass of the sample initial of the detergent composition introduced into the Sotax. He average percentage residue remaining in two identical samples provides the value of the Waste Index.

The waste index for compositions detergents of the invention do not have to be greater than 25, being preferably not more than 20 and still more preferably not greater than 15.

The secondary waste index is calculated from following way:

using the same device, 800 are introduced ml of deionized water in the Sotax apparatus and heated until constant temperature of 20 ° C at a stirrer speed of 21 rad / s (200 rpm). Then add 2 grams of product to the deionized water and stirred at a stirrer speed of 21 rad / s (200 rpm) for 20 minutes. After 20 minutes the deionized water containing the detergent sample through a circle of black C70 fabric (from Empirical Manufacturing Company) placed in a Buchner funnel with the smooth side of the fabric upwards. The black tissue is removed from the Buchner funnel and placed On a sheet of paper. The black tissue is allowed to dry room temperature for 24 hours. Three replicates are made for each trial and an average percentage waste is calculated that it is in the circle of black tissue as a proportion of the sample Total detergent introduced into the Sotax.

The average residues of the three replicates supply the value of the Secondary Waste Index, which has to be a maximum of 15. Preferably, the Waste Index maximum secondary is 10, even more preferably, the Index of Maximum secondary waste can be 5 or less.

Example 1

A detergent composition was prepared which it comprised blown dust, an agglomerate that comprised silicate crystalline laminar and anionic surfactant, a particle effervescent and a mixed bleach activator particle dry, sodium percarbonate, sodium citrate and suppressant suds.

The individual particles were prepared and mixed together dry by gentle mixing, e.g. eg in a Nautamixer for a time of at least 4 minutes.

Preparation of blown dust

The composition of the final blown powder was the next:

Ingredient % in powder blown Rent linear chain sodium sulphonate (THE) twenty Acid copolymer acrylic / maleic acid 5 Sulfate of sodium 16 Carbonate sodium 31 Citrate of sodium twenty Water 8

       \ vskip1.000000 \ baselineskip
    

The blown powder was prepared by a process standard spray drying. The above ingredients are mixed with water to form an aqueous suspension. The suspension Aqueous can be prepared by a batch or continuous process. In the case at hand, a batch mixer or "closed mixer" where they dissolved, or formed a suspension, with water the various detergent components for obtain an aqueous suspension containing 35% water. The content of water can vary from about 20% to about 60% in water weight, preferably it is about 30% at approximately 40% by weight of water. In this example, the order of adding the ingredients to the water to form the aqueous suspension was the one indicated above in the final powder composition blown. The aqueous solution was then pumped under pressure. elevated through atomizing nozzles inside a tower spray drying, in which excess water was removed, obtaining a fluid powder product (blown powder). The Fine particles were screened through a sieve.

Preparation of the laminar silicate particle crystalline / anionic surfactant

The particle was obtained through a process of roller compaction. Raw materials in proportions indicated above were fed, applying a force of 80 kN compression, inside a Pharmapaktor L200 / 50 roller P, provided with concave smooth rollers with an axial undulation installed 0.3 mm. The scales produced were compacted to then using a Flake Crusher FC 200 with a size of mesh selected to produce the required particle size. The product was screened to remove fine particles.

These three components were mixed with the Additional dry added ingredients related to then, in the proportions indicated below, to obtain a detergent composition according to the invention.
