Definitions
- the present invention relates to a process for preparing a particulate detergent composition, in particular by spray drying an aqueous slurry. Particulate detergent compositions are also disclosed.
- powder structurants useful to achieve a crisp, free-flowing spray-dried powder.
- film-forming polymer for example, polycarboxylates (for example, US-A-4 379 080); polyacrylates (for example, JP204098/1983); sucrose and derivatives (for example, EP-A-0 215 637) ; sodium sesquicarbonate (for example, EP-A-0 242 138).
- powder structurants are required by the formulator as active ingredients, then they are an expensive processing aid.
- aqueous slurry which does not comprise either water-soluble silicate, or one of the alternative powder structurants is difficult to spray dry.
- high water concentrations are generally needed in order to maintain the viscosity of the slurry low enough to provide crisp, free-flowing particles of the desired particle size when spray-dried.
- the disadvantage of high water concentrations is that the excess water must be removed during the drying step and a lot of energy is needed to do this.
- WO90/04630 published on 3rd May 1990, describes a process for preparing a carbonate containing detergent slurry comprising an alkylpolyglycoside and an alkali metal chloride.
- Zeolite A is suggested as one possible builder albeit in the presence of silicate (at 7% by weight in Table VI).
- the object of the present invention is to avoid residue problems by substantially omitting silicate from an aqueous slurry which comprises anionic surfactant and aluminosilicate, and at the same time to provide a low viscosity slurry suitable for spray-drying to form crisp, free-flowing powder.
- this object is achieved by forming an aqueous slurry which further comprises less than 5% by weight of silicate and at least 1% by weight of an inorganic salt, or a mixture of inorganic salts, and whereby the addition of the inorganic salt increases the ionic conductivity of the aqueous slurry, and subsequently drying the aqueous slurry to form the particulate detergent composition.
- the inorganic salt is an alkali metal or alkaline earth metal salt, or mixtures thereof of halide, nitrate or citrate, most preferably sodium chloride.
- the step of adding the inorganic salt raises the ionic conductivity of the aqueous slurry by at least 3 milliSiemens, and preferably by at least 5 milliSiemens.
- a further aspect of the invention concerns spray-dried detergent powder compositions.
- Preferred compositions comprise:
- Essential components of the compositions of the present invention are aluminosilicate builders such as those having the empirical formula: M z (zAlO 2 ) y ] ⁇ x H 2 O wherein z and y are integers of at least 6, the molar ratio of z to y is in the range from 1.0 to about 0.5, and x is an integer from about 15 to about 264.

- polyacrylamides polyacryl
- polystyrene resin polystyrene resin
- suitable polymers are polyamine N-oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, polyvinylpyrrolidone polymers, polyvinyloxazolidones and polyvinylimidazoles or mixtures thereof.
- Polymeric polycarboxyate builders are set forth in U.S. Patent 3,308,067, Diehl, issued March 7, 1967. Such materials include the water-soluble salts of homo-and copolymers of aliphatic carboxylic acids such as maleic acid, itaconic acid, mesaconic acid, fumaric acid, aconitic acid, citraconic acid, methylenemalonic acid, methyl acrylic and PEG.
- polymeric polycarboxylates are substantially omitted from the aqueous slurry. By substantially omitted, less than 5% by weight of the aqueous slurry is preferred, and less than 2% by weight is more preferred.
- the inorganic salt should result in an increased ionic conductivity of the aqueous slurry.
- the ionic conductivity of the aqueous slurry depends not only on the inorganic salt used, but also on the amount of inorganic salt used, and also on the composition of the aqueous slurry. Halides, especially chlorides, nitrates and citrates have been found to be particularly effective inorganic salts which when used at the preferred levels, have the effect of increasing the ionic conductivity of the aqueous slurry.
- Carbonates and sulphates are less effective, and may well cause a decrease in the ionic conductivity of the slurry.
- the higher ionic conductivity of the aqueous slurry suppresses the formation of highly viscous surfactant phases which are subsequently difficult to dry. By promoting less viscous surfactant phases the aqueous slurry is more readily formed into free-flowing, crisp particles having a good particle size distribution.
- Particulate suds suppressors may also be incorporated into the finished composition by dry adding.
- the suds suppressing activity of these particles is based on fatty acids or silicones.
- compositions of the present invention can be included in the compositions of the present invention. These include flow aids, color speckles, bleaching agents and bleach activators, suds boosters or suds suppressors, antitarnish and anticorrosion agents, soil suspending agents, anionic and nonionic soil release agents, dyes, clays, flocculating agents, STS, fillers, optical brighteners, germicides, pH adjusting agents, nonbuilder alkalinity sources, hydrotropes, enzymes, enzyme-stabilizing agents, chelating agents, (including EDDS) and perfumes.
- flow aids include color speckles, bleaching agents and bleach activators, suds boosters or suds suppressors, antitarnish and anticorrosion agents, soil suspending agents, anionic and nonionic soil release agents, dyes, clays, flocculating agents, STS, fillers, optical brighteners, germicides, pH adjusting agents, nonbuilder alkalinity sources, hydrotropes, enzymes, enzyme-stabilizing agents,
- These optional ingredients may be incorporated either directly in the agglomerates herein or may be components of separate particles suitable for dry adding to the agglomerates of the present invention.
- the aqueous slurry may be prepared by a batch or continuous process. Most conveniently a batch mixer, or “crutcher” is used in which the various detergent components or dissolved in, or slurried with, water. Typically the aqueous slurry contains from about 20% to about 60% by weight of water, in particular from about 30% to about 40% by weight of water. This is referred to as the crutcher mix moisture. In the process of the present invention, the order of addition of the inorganic salt and the other components of the aqueous slurry (or “crutcher mix") is not considered to be critical.
- the ionic conductivity of the aqueous slurry which comprises the inorganic salt must be greater than the ionic conductivity of the aqueous slurry in the absence of the inorganic salt. It is preferred that the addition of the inorganic salt results in an aqueous slurry having an ionic conductivity which is at least 3 milliSiemens higher than a corresponding aqueous slurry from which the inorganic salt has been omitted.
- the drying of the aqueous slurry may be achieved by any one of several processes known to the skilled man, but it is preferably prepared by spray drying. Following the spray drying route, an aqueous slurry is prepared comprising the solids. The slurry is then pumped at high pressure through atomising nozzles into a drying tower where excess water is driven off, producing a flowable powder. The resulting powder may then be oversprayed with liquid ingredients, especially nonionic surfactants for which the powder has a high adsorption capacity before it loses its good flow characteristics. Other powdered components of the finished laundry detergent may be dry mixed with the flowable powder produced by the above process.

- the aqueous slurry is heated to 70°C and is fed through to a series of pressure pumps. This increases the pressure of the mix up to 80 bar. Air is then injected into the mix at a pressure of 100 bar. The high pressure mix is then directed to the top of the spray drying tower. Here it is blown through a set of nozzles, which range in aperture diameter up to 1mm. These atomise the slurry into droplets. The moisture is driven off these particles as they fall through the tower with a residence time of up to 180 seconds by contact with hot air at 275°C. At the bottom of the tower a blown powder is collected with a density in the range of 300 - 550g/l. The resulting blown powder has a moisture in the range of 5 -_15% with the majority of the particles having a size in the range of 150 - 1200 micrometers.
