Description
DETERGENT COMPOSITIONS
TECHNICAL FIELD
The present invention relates to detergent compositions or to components thereof which contain a specific cationic surfactant to be used under alkaline washing conditions, which has a carefully selected counter-ion. The detergent compositions of the invention are to be used in any detergency field, including household cleaners, but are generally used in laundry and dishwashing processes to provide improved benefits of greasy stain removal and cleaning benefits.
BACKGROUND OF THE INVENTION
The use of cationic surfactants in detergent compositions is known. For example, GB 2040990A discloses granular detergent compositions comprising cationic surfactants. EP-A-121949 discloses surfactants to be used in laundry detergent compositions. This reference describes a broad class of cationic surfactants.
Applicants have found that a particular group of cationic quaternary ammonium surfactants provide good cleaning properties, especially on greasy, oily stains. It has been found that cationic compounds are particularly beneficial in detergent compositions that additionally include anionic surfactants. Without being limited to the theory, the applicant believes that the particular surfactants used in the detergent compositions of the present invention surprisingly have good solubility. In addition, these are associated in the presence of anionic components to produce, surprisingly, anionic / cationic complexes which lead to unexpected performance benefits: the cationic surfactant is contacted quickly and effectively with the greasy spots and rapidly penetrating and breaking the stain providing effective removal of greasy stains. It is further believed that, after breaking the greasy dirt, the cationic surfactants used in the present invention also form complexes with the fatty acids and any other negatively charged product from the break, increasing their solubility and increasing the removal of oily dirt, oily and overall cleaning performance. However, it has been found that some surfactants can produce unpleasant odors during processing or use under alkaline detergent conditions in the wash solution. Without being limited by theory, applicants believe that odors arise as a result of the exchange of the counterion of the cationic surfactant with hydroxide ions in the aqueous alkaline wash solution. The resulting quaternary ammonium hydroxide product can then produce amine byproducts with unpleasant odors. To adequately avoid this problem during use in alkaline conditions, the particular cationic surfactants must have a counter ion having a higher relative selectivity towards the cationic surfactant than that of the hydroxide ion in aqueous solution under the conditions of use. All documents cited in the present description are incorporated herein by reference.

The maximum amount of cationic surfactant can even be as low as 1% by weight. The benefits of the invention are found even with very small amounts of the cationic surfactant of the formula I. In general, there will be at least 0.01% by weight, preferably at least 0.05% or at least 0.1% by weight of the surfactant cationic in the detergent compositions of the invention. In formula I, R1 is a hydroxyalkyl group having no more than 6 carbon atoms, and preferably, the -OH group is separated from the quaternary ammonium nitrogen atom by not more than 3 carbon atoms. Preferred R1 groups are -CH2CH2OH, -CH2CH2CH2OH, -CH2CH (CH3) OH and -CH (CH3) CH2OH. More preferred are the groups -CH2CH2OH and -CH2CH CH2OH, and -CH2CH2OH is particularly preferred. Preferably, R2 and R are each selected from ethyl and methyl groups, and most preferably both R and R3 are methyl groups. The R groups that are preferred have at least 6, or even at least 7, carbon atoms. R4 could have no more than 9 carbon atoms or even no more than 8 or 7 carbon atoms. R can be C5..9 or Cu The R groups that are preferred are linear alkyl groups. Linear R groups having from 8 to 11 carbon atoms, or from 7 to 9 carbon atoms are preferred. The counter ion X in formula I can be any counterion that is not substantially exchanged with the hydroxide ion in aqueous solution at 0.5% by weight of the detergent composition at 20 ° C, so as to substantially prevent the formation of malodorous compounds. . An appropriate method for determining whether the counterion is substantially or not exchanged with the hydroxide ion is described in J. Phis.

Generally the appropriate counterions have an electronegativity greater than that of the hydroxide ions. The preferred examples are chloride ions, bromide and nitrate, and of these the chloride ion is particularly preferred. Although pure or substantially pure cationic compounds are within the scope of this invention, it has been found that mixtures of cationic surfactants of the formula I can be particularly effective, for example, mixtures of surfactants in which R can be a combination of linear alkyl groups of Cg and IQ, O alkyl groups of C9 and C ^.

Said particles are preferably prepared by an extrusion process. The bulk density of the granular detergent compositions according to the present invention is typically a bulk density of at least 400, preferably 600 g / liter, most preferably from 650 g / liter to 1200 g / liter. The bulk density is measured by means of a simple funnel and cup device consisting of a conical funnel rigidly molded on a base and provided with a butterfly valve at its lower end to allow the contents of the funnel to be emptied into a cup axially aligned cylindrical arranged below the funnel. The funnel is 130 mm high and has internal diameters of 130 mm and 40 mm in its respective upper and lower extremities. It is mounted in such a way that the lower extremity is 140 mm above the upper surface of the base. The cup has a total height of 90 mm, an internal height of 87 mm and an internal diameter of 84 mm. Its nominal volume is 500 ml. To carry out a measurement, the funnel is filled with manually poured dust, the butterfly valve is opened and the powder is allowed to overfill the cup. The full cup is removed from the frame and the excess powder is removed from the cup by passing a straight edge implement, v.gr. , a knife, through its upper edge. The filled cup is then weighed and the value obtained for the weight of the powder is doubled to provide a bulk density in g / liter. Repeated measurements are made as required. The compacted solids can be manufactured using any suitable compaction process, such as rattling, agglomeration or extrusion, preferably tableting. Preferably, the tablets to be used in dishwashing processes are manufactured using a normal rotary clack press and using compression forces of 5 to 13 KN / cm, most preferably 5 to 11 KN / cm2 for the solid compacted has a minimum hardness of 176N to 275N, preferably 195N to 245N, measured by a C100 hardness test as provided by I. Holland instruments. This method can be used to prepare homogeneous or stratified tablets of any size or shape. Preferably, the tablets are symmetrical to ensure uniform dissolution of the tablet in the wash solution.
Laundry Washing Method The laundry washing methods of the present invention typically comprise treating the laundry with an aqueous washing solution in a washing machine having dissolved or supplied therein an effective amount of a laundry detergent composition in accordance with the present invention. with the invention For an effective amount of the detergent composition it is tried to say from lOg to 300g of product dissolved or dispersed in a washing solution of a volume of 5 to 65 liters, which are typical doses of product and in volumes of washing solution commonly used in conventional laundry washing methods. The dosage depends on the particular conditions such as water hardness and degree of soiling of the laundry. The detergent composition can be supplied, for example, from the assortment box of a washing machine or it can be sprinkled on the dirty laundry placed on the machine. In one aspect of use, a delivery device is employed in the washing method. The delivery device is loaded with the detergent product and used to introduce the product directly into the drum of the washing machine before starting the washing cycle. Its volume capacity must be such that it is capable of containing sufficient detergent product that would normally be used in the washing method. The delivery device containing the detergent product is placed inside the drum before the start of the washing cycle, before, simultaneously with or after the washing machine has been loaded with clothes. At the beginning of the washing cycle of the washing machine, water is introduced into the drum and it rotates periodically. The design of the delivery device must be such as to allow the dry detergent product to be contained but then allow this product to be released during the wash cycle in response to its agitation when the drum is rotated and also as a result of its contact with the washing liquid. To allow the release of the detergent product during washing, the device may possess a number of openings through which the product can pass. Alternatively, the device may be made of a material that is liquid permeable but impermeable to the solid product, which will allow the dissolved product to be released. Preferably, the detergent product will be released rapidly at the start of the wash cycle, thereby providing transient localized concentrations of the product in the washing machine drum at this stage of the wash cycle. Preferred delivery devices are reusable and designed in such a way that the integrity of the container is maintained both in the dry state and during the wash cycle. Especially preferred delivery devices for use with the composition of the 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. An article by J. Bland, published in Manufacturing Chemist, November 19889, p. 41-46, also discloses especially preferred supply devices for use with granular laundry products, which are of a type commonly known as "granulette". Another preferred delivery device for use with the compositions of this invention is described in PCT patent application No. W094 / 11562. Essentially preferred delivery devices are described in European Patent Application Publication Nos. 0343069 and 0343070. This application describes a device comprising a flexible liner in the form of a pouch extending from a support ring defining a hole, the orifice being adapted to admit sufficient product into the bag for a washing cycle in a washing process. A portion of the washing medium flows through the orifice into the bag, dissolves the product and the solution then passes down through the orifice into the washing medium. The support ring is provided with a masking arrangement to prevent the exit of the wetted and undissolved product, this arrangement typically comprising radial walls extending from a protrusion in a spoke wheel configuration or similar structure, in which the walls have a helical shape. Alternatively, the delivery device may be a flexible container, such as a bag or bag. The bag may be made of a fibrous structure coated with a waterproof protective material to retain the contents, such as that described in published European patent application No. 0018678. Alternatively, it may be formed of a synthetic polymeric material insoluble in water provided with an edge seal or closure designed to break in the aqueous medium as described in published European patent applications Nos. 0011500, 0011501, 0011502 and 0011968. A convenient form of water-curable closure comprises a soluble adhesive in water disposed along and sealing an edge of a sack formed of a waterproof polymeric film such as polyethylene and polypropylene.
Automatic dishwashing method Any suitable methods for automatic dishwashing or the cleaning of dirty cutlery, particularly dirty silverware, are envisioned. An automatic dishwashing method that is preferred comprises treating selected articles of earthenware, glassware, pots, silverware and cutlery, and mixtures thereof, with an aqueous liquid having dissolved or dispersed therein an effective amount of a composition for the automatic dishwashing according to the invention.
