Definitions
- the present invention relates to a detergent composition
- a detergent composition comprising cationic and anionic surfactants and an acid and alkali source, which is suitable for use in laundry washing and dish washing methods.
- detergents which provide improved cleaning and stain removal. Therefore, in the recent past detergents have been developed which contain high levels of surfactant and various types of surfactants, such as anionic, nonionic and cationic surfactants.
- the high density detergents comprising high levels of surfactants can lead to poor solubility properties, arising from low rate of dissolution or the formation of gels, and thus to poor dispensing ofthe product, either from the dispensing drawer of a washing machine, or from a dosing device placed with the laundry inside the machine.
- This poor dispensing is often caused by gelling of particles, which have high levels of surfactant, upon contact with water.
- the gel prevents a proportion of the detergent powder from being solubilized in the wash water which reduces the effectiveness of the powder. This is a particular problem at low water pressures and/or at lower washing temperatures.
- WO94/28098 discloses a non-spray-dried detergent powder comprising a combination of an ethoxylated primary C8-18 alcohol, an alkali metal aluminosilicate builder and 5 to 40 wt% of a water-soluble salt of a citric acid.

- the mean particle size ofthe base composition of granular compositions in accordance with the invention can be from 0.1 mm to 5.0 mm, but it should preferably be such that no more that 5% of particles are greater than 1.7mm in diameter and not more than 5% of particles are less than 0.15mm in diameter.
- the term mean particle size as defined herein is calculated by sieving a sample ofthe composition into a number of fractions (typically 5 fractions) on a series of Tyler sieves.

The mean particle size is taken to be the aperture size through which 50% by weight of the sample would pass.
- the bulk density of granular detergent compositions in accordance with the present invention typically have a bulk density of at least 600 g/litre, more preferably from 650 g/litre to 1200 g/litre.
- Bulk density is measured by means of a simple funnel and cup device consisting of a conical funnel moulded rigidly on a base and provided with a flap valve at its lower extremity to allow the contents ofthe funnel to be emptied into an axially aligned cylindrical cup disposed below the funnel.
- the funnel is 130 mm high and has internal diameters of 130 mm and 40 mm at its respective upper and lower extremities. It is mounted so that the lower extremity is 140 mm above the upper surface ofthe base.
- the cup has an overall height of 90 mm, an internal height of 87 mm and an internal diameter of 84 mm. Its nominal volume is 500 ml.
- the funnel is filled with powder by hand pouring, the flap valve is opened and powder allowed to overfill the cup.
- the filled cup is removed from the frame and excess powder removed from the cup by passing a straight edged implement eg; a knife, across its upper edge.
- the filled cup is then weighed and the value obtained for the weight of powder doubled to provide a bulk density in g/litre. Replicate measurements are made as required.
- the surfactant system herein is preferably present in granular compositions in the form of surfactant agglomerate particles, which may take the form of flakes, prills, marumes, noodles, ribbons, but preferably take the form of granules.
- the most preferred way to process the particles is by agglomerating powders (e.g. aluminosilicate, carbonate) with high active surfactant pastes and to control the particle size ofthe resultant agglomerates within specified limits.
- Such a process involves mixing an effective amount of powder with a high active surfactant paste in one or more agglomerators such as a pan agglomerator, a Z-blade mixer or more preferably an in-line mixer such as those manufactured by Schugi (Holland) BV, 29 Chroomstraat 821 1 AS, Lelystad, Netherlands, and Gebruder Lodige Maschinenbau GmbH, D-4790 Paderbom 1 , Elsenerstrasse 7-9, Postfach 2050, Germany. Most preferably a high shear mixer is used, such as a Lodige CB (Trade Name).
- a high active surfactant paste in one or more agglomerators such as a pan agglomerator, a Z-blade mixer or more preferably an in-line mixer such as those manufactured by Schugi (Holland) BV, 29 Chroomstraat 821 1 AS, Lelystad, Netherlands, and Gebruder Lodige Maschinenbau GmbH, D-4790 Paderbom 1
- a high active surfactant paste comprising from 50% by weight to 95% by weight, preferably 70% by weight to 85% by weight of surfactant is typically used.
- the paste may be pumped into the agglomerator at a temperature high enough to maintain a pumpable viscosity, but low enough to avoid degradation ofthe anionic surfactants used.
- An operating temperature ofthe paste of 50°C to 80°C is typical.
- the detergent composition has a density of greater than about 600 g/1 and is in the form of powder or a granulate containing more than about 5% by weight ofthe alkali, preferably (bi-) carbonate or percarbonate.
- the carbonate material is either dry-added or delivered via agglomerates.
- the addition ofthe acid, preferably citric acid, (up to 10%) may be introduced into the product as a dry-add, or via a separate particle.
- Machine laundry methods herein typically comprise treating soiled laundry with an aqueous wash solution in a washing machine having dissolved or dispensed therein an effective amount of a machine laundry detergent composition in accord with the invention.
- an effective amount ofthe detergent composition it is meant from 40g to 300g of product dissolved or dispersed in a wash solution of volume from 5 to 65 litres, as are typical product dosages and wash solution volumes commonly employed in conventional machine laundry methods.
- a dispensing device is employed in the washing method.
- the dispensing device is charged with the detergent product, and is used to introduce the product directly into the drum ofthe washing machine before the commencement of the wash cycle. Its volume capacity should be such as to be able to contain sufficient detergent product as would normally be used in the washing method.
- the dispensing device containing the detergent product is placed inside the drum.
- water is introduced into the drum and the drum periodically rotates.
- the design of the dispensing device should be such that it permits containment of the dry detergent product but then allows release of this product during the wash cycle in response to its agitation as the drum rotates and also as a result of its contact with the wash water.
- the device may possess a number of openings through which the product may pass.
- the device may be made of a material which is permeable to liquid but impermeable to the solid product, which will allow release of dissolved product.
- the detergent product will be rapidly released at the start of the wash cycle thereby providing transient localised high concentrations of product in the drum of the washing machine at this stage ofthe wash cycle.
- Preferred dispensing devices are reusable and are designed in such a way that container integrity is maintained in both the dry state and during the wash cycle.
- Especially preferred dispensing devices for use with the composition ofthe invention have been described in the following patents; GB-B-2, 157, 717, GB-B-2, 157, 718, EP-A-0201376, EP-A-0288345 and EP-A-0288346.
