COMPOSITIONS NON-AQUEOUS DETERGENTS CONTAINING PARTICULATE MATERIAL FIELD OF THE INVENTION This mvenc on refers to non-aqueous detergent products for laundry that are on the shelf of a liquid, gel or paste and that are in the form of stable dispersions of material in μar + icul s, such as Manqueo agents and activators of Manqueo.

BACKGROUND OF THE INVENTION cjß often considers that detergent products in the form of liquid, gel or paste are more convenient to use than dry detergent or powder products. Therefore, said detergents have found substantial acceptance by consumers. All detergent products are easily measured, quickly dissolve in the washing solution, and are capable of being easily applied in concentrated solutions or dispersions to soiled areas in garments that are washed, and do not leave a dust coat. They also often take up less storage space than granular products. Purely such detergents can incorporate materials that may not be incorporated into their formulations. support drying operations without deterioration, whose operations are frequently used on 1? ? abr? falls? of do producios of the people granulai is or do material on particles. Although said detergents have several advantages over granular detergent products, they also inherently possess several disadvantages. In particular, the components of the detergent composition, which may be compatible with one another in granular products, may tend to interact or react with each other. Thus, such components as enzymes, tensio-active agents, perfumes, brighteners, etc. Solvents and especially bleaching agents and bleach activators, can be specifically difficult to incorporate into liquid detergent products that have an acceptable chemical stability graph. An alternative to increase the chemical compatibility of The composition of the detergent composition in detergent products has been to formulate non-aqueous (or anhydrous) detergent compositions. In said non-aqueous products, at least some of the components of the normally solid detergent composition tend to remain more soluble in the liquid product and, therefore, are less reactive with any other than if they had dissolved in the matrix. qu.da. Detergent compositions Non-aqueous liquids, including those containing reactive materials such as peroxygen bleaching agents, have been described, for example, in Heprth et al., U.S. Pat. 4,615,820, presented on October 1, 1906; Schultz et al., Patent of F.U.A. 1, 929, JÜC1, filed 29 of Hayo do 1 0; chult et al., patent of L.U.A. 5,000,031, filed lbr of nbr *? 1 of 1901; Eider et al., EP-A 030,096, published on June 10. { ) of 1981; Hall and others, UO 9? / 09B?

The difficulties that have been observed with the incorporation of bLanqueo activators in detergents do not aqueous, they include the chemical and / or physical stability of the activators of Manqueo. EP 339 995 discloses a non-aqueous liquid detergent composition comprising a per-salt bleach and a precursor and, therefore, the composition contains a blocked non-ionic alkoxylated surfactant. FP 540 L5 090 proposes to use a bleach precursor that is relatively insoluble in the non-aqueous liquid phase of L? composition of liquid waste. One difficulty associated with the stability of bleach activators is that, after being diluted in the In the case of a washing solution, the bleach activators need to have a certain degree of solubility high enough to be effective as a kind of bleaching in the washing solution. Given the foregoing, there is clearly a continuing need to identify and provide non-aqueous ergent compositions containing a bleach activator in the form of liquid, gel or paste products having a high grade.of chemical stability in the concentrate, together with an efficiency of efficient bleaching in 1"wash solution. Therefore, it is an object of the present invention to provide a non-aqueous detergent composition, wherein the bleach activators are chemically stable in the concentrate while, at the same time, it is still effective as a type of bLanking in the solution. of Washing. ?) e conform to the present? invention, a non-aqueous detergent composition is provided which is in the form of a liquid, gel or paste, containing a bleaching agent and a bleach activator which is present as a divalent metal salt, a trivalent metal salt, or a mixed metal salt, according to which at least one of the salts is a trivalent di-metal salt, or mixtures thereof.

These include oxygen bleaches, as well as other agents for bleaching. In the present invention, perborate bleach may be used, for example, sodium perborate (eg, mono- or tetrahydrated J). Peroxygen bleaching agents are preferably used in the compositions. Suitable peroxygen bleaching agents include perborate, sodium bicarbonate, butyl bromide and bleach of "perearbonat" or equivalent, sodium peroxyhydrate pyrophosphate, per-oxy, urea hydrate and sodium peroxide. The bleach activators according to the present invention are present as a divalent metal salt and / or tr value, and the salt of the bleach activator can be added as a binder, for example OXONE, manufactured by DuPont. a dispersed powder in non-aqueous L? base.

The whitening activator can also be used with a non-aqueous liquid product such as a non-ionic agent, organic solvent and / or mixtures thereof. The salts of the bleaching agent can be obtained by any known method for preparing divalent metal salts of ammonium surfactant solutions. The salts of the bleach activator of the present invention may comprise salts, whereby at least one of the salts is a divalent or trivalent salt; Mixed salts are obtained by co-crystallization of the salts of the bleach activator. The mixed salts may comprise a monovalent salt. Examples of these salts are Na3l1g 4 UN-nonanoyl-h-arninohexanoyloxy benzenesulphonate. Preferred salts according to the present The invention is salts of Ca, Mg and Al. Highly preferred are the salts of Ca and Mg, or mixtures thereof.

A residual group is any group that is displaced from the bleach activator as a consequence of the nucleophilic attack, on the bleach activator, by the dropping anion. This, the reaction of perhydric acid, results in the formation of peroxyl carboxylic acid. In general, for a group to be an adequate residual group, it must exert an electron-attracting effect. It should also form a in stable condition, so that the speed of the reverse reaction is negligible. This facilitates the ionic core attack by the hydrogen ion. Group L must be sufficiently reactive for the reaction to take place within the optimal time frame (eg, a Wash cycle). however, if L is too reactive, this activator will be difficult to stabilize-to utilize-1 or in a bleaching composition. These characters *? Stories are general in and equaled by the pKa of conjugated acid from the residual group, although exceptions to this convention are known. Typically, residual groups exhibiting such behavior are those in which their conjugated acid has a pKa on the scale of about 4 to about 13, preferably about 6 to about 11, and preferably about from 8 to about 11. Preferred bleach activators are those of the above general formula, wherein Ri, R2 and RS on as defined for the peroxyacid, and L is selected from the group consisting of: and mixtures thereof, wherein R1 is an alkyl, ryl or alkapol group containing from about 1 to about 14 carbon atoms, R3 is an alkyl chain containing At about tom carbon atoms, R * is H or R3, and Y is an ammonium solubilizer group.

L5 Such activators are described in U 4,634,551 and US 4,852,989. The important class of ion bleach activators provides organic peracids as described in the present invention by ring opening as a consequence of the nucleophile attack on the carbon of the cyclic ring, on the perhydroxide anion. . For example, this reaction of opening of the aniLlo in certain activators includes the attack on the carbom to the lactam ring by the per-oxide of hydrogen or its anion. Since the attack of an acyl lactase by * the hydrogen peroxide or an anion * occurs preferentially in the exocyclic carbom, obtaining a significant fraction of the ring opening may a totalizer require., or an example of money laundering assets? you? The ring can be found in other activators, such as those described in the US patent. / ?, 966, r23, by Hodge et al., Filed on October 30, 1990. Surprisingly, it has now been found that the bleach activators of the present invention are in contrast to the salts of the bleach activator. monovalent, are chemically stable in the concentrate while, at the same time, they are effective as a bleaching species in the wash solution.
