The technical field to which the invention relates.

The present invention relates to solid detergent compositions for washing containing anionic cleansing surfactant and a highly porous media. The compositions of the present invention have good purification efficiency, good distribution profiles and dissolution, and good physical characteristics.

The level of technology

Relatively recently, many manufacturers of detergents, attempts were made to significantly improve the efficiency of the solubility and distribution of their granular detergents for washing. The approach of many manufacturers of detergents focuses on significant reduction or even complete removal of water-insoluble additives such as zeolite additives in the compositions of granular detergents for washing or from these compositions. However, due to the exclusion from circulation of phosphates in many countries due to laws that prohibit manufacturers of detergents to include a sufficient number of water-soluble detergent components based on phosphates such as sodium tripolyphosphate, in the composition of the granular detergents for washing, and also due to the lack of alternatives nevospolnim water-soluble detergent components on the vent manufacturers of detergents, the approach of many manufacturers of detergents focused not on a complete replacement system based on zeolite detergent component system water-soluble detergent component having a uniform content of detergent, and the creation of unfinished songs granulated detergent for washing.

Although this "unfinished" approach significantly improves dissolution and dispersible granular detergent for Laundry, there are problems with a large number of cations, such as calcium, which are not removed from the washing solution during the washing system main cleaning component of the composition of the granulated detergent for washing. These cations interfere with the system of anionic cleansing surfactants (surfactant) granular detergent composition for washing those that cause the precipitation of anionic cleansing surfactants from solution, resulting in reduced activity and cleaning ability of anionic cleansing surfactant. In extreme cases, such water-insoluble complexes can Deposit in tissues, leading to poor preservation of the white and poor performance of the integrity of the tissue. This is a particular problem when the detergents used for washing in hard water with a high concentration is tion of calcium ions.

Another problem to be solved, when the content of water-insoluble detergent components, such as zeolites, in the composition is significantly reduced, or when such zeolites are completely removed from the composition are poor physical characteristics of this composition, in particular after storage, resulting in poor strength of the sediment.

The inventors have found that the cleaning ability and physical characteristics of the built detergent compositions are improved with the use of anionic cleansing surfactant in combination with a highly porous material medium.

U.S. patent 5.552.078 (Carr et al., Church & Dwight Co. Inc.) relates to a powder detergent composition for washing containing the active surfactant. It is argued that the composition according to the U.S. patent 5.552.078 exhibit excellent cleaning and whitening of fabrics, allowing you to avoid the problems associated with eutrofikatsija that occurs in the presence of significant quantities of phosphate detergent component in the composition, and minimizing the problem of deposition in tissue, often occurring when the composition contains large quantities of carbonate detergent component.

In U.S. patent 6.274.545 B1 (Mazzola, Church & Dwight Co. Inc) described powder washing composition for washing, containing many carbonate and a little phosphate, which can be is successfully used when washing fabrics in cold water, in this case the residual amount of insoluble residue of the detergent in the solution is minimal. Washing composition according to the U.S. patent 6.274.545 B1 contains a mixture of anionic/nonionic surfactant, which is a partially sulfonated and neutralized ethoxylated surfactant alcohol and ingredient polyethylene glycol, which presumably increases the solubility of the solid detergent in the washing solution.

Application WO 97/43366 (Askew et al., The Procter&Gamble Company) discloses a detergent composition containing a foaming system, and gives examples of detergent compositions containing carbonate detergents, and do not contain bleach.

Application WO 00/18873 (Hartshorn et al., The Procter&Gamble Company) relates to detergent compositions having, as is alleged, good metering characteristics and leaves no traces on the fabric after washing.

Application WO 00/18859 (Hartshorn et al., The Procter&Gamble Company) relates to detergent compositions having allegedly superior release of ingredients in the washing solution in the washing process. Composition application WO 00/18859, as approved, does not form a gel upon contact with water and, allegedly, do not leave insoluble residues on clothes after washing. Compositions according to the application WO 00/18859 contain predominantly water-soluble detergent component, to which were directly mixed with the surface-active substance.

Application WO 02/053691 (Van der Hoeven et al., Hindustian Lever Limited) relates to detergent compositions for washing, containing more than 10 wt.% insensitive to calcium surfactants, from 0.1 wt.% up to 10 wt.% strong main detergent component selected from phosphate and (or) zeolite detergent components, and less than 35 wt.% non-functional water-soluble inorganic salts that do not have an alkaline reaction.

For anionic cleansing surfactants may be preferred such a structural modification, in which the anionic cleansing surfactant is less sensitive to calcium, as well as to the loss of the washing solution in the presence of free calcium ions. This structural modification may be effected by the introduction of a methyl or ethyl group near the head group of anionic cleansing surfactant, which can lead to less sensitivity to calcium due to steric hindrance of the head group, and to decrease the ability of anionic cleansing surfactants for complexation with the participation of free calcium cations, thus to cause the precipitation from solution. Other structural modifications include the introduction of functional groups such as amine groups, alkyl chain anionic cleansing surfactant; this may result in reduced sensitivity of anionic cleansing surfactant to calcium due to the presence of alkyl chains of the surfactant group, which can minimize the undesirable physicochemical property of anionic cleansing surfactant to form a homogeneous crystalline structure in the washing solution in the presence of free calcium ions. This reduces the tendency of anionic ochimusha to fall out of solution.
