Abstract

The invention provides a method for improving the dispensing of a detergent composition or component thereof, comprising a surfactant and other detergent components, by providing a detergent composition comprising an intimate mixture of the surfactant component or part thereof and a crystalline layered silicate.

Description

Method to dispense.

Technical field

The invention relates to the use of a component specific detergent in detergent compositions for improvement of dispensing the product or its components.

Background of the invention

In recent decades, the efforts of research have been directed to the development of detergents that They have an improved cleaning capacity. Additionally, the focus has been on developing products high density detergents.

It has recently been found that one of the main complaints of detergent users is that Products are not always dispensed or dissolved satisfactorily. This results in the formation of product residues in the drawer of dispensed, in the washing machine also in the fabrics after washing, for example in the form of a gel or of powder residues. This can pose a problem especially with high density products, in cold water wash conditions or when quantities are used limited water in the washing process, for example in the phase initial of the washing process, when small amounts of water come into contact with the product in the dispensing drawer or in the inside of the washing machine

The inventors have found that various detergent ingredients can cause these problems. They have found that in particular certain surfactants can form gels in initial contact with water. The inventors have also found that dense granules comprising high levels of surfactants, dense granules comprising high levels of aluminosilicates, and granules comprising high levels of water, can cause gelation and dissolution problems. For example, crystalline laminar silicate agglomerates comprising high water levels are described in WO92 / 07932 (Procter & Gamble), which anyway describes aluminosilicates as preferred detergent builder ingredients against lamellar silicates crystalline EP-425804 describes particles comprising high levels of aluminosilicate, surfactant and crystalline lamellar silicates. These agglomerates known in the art are often exactly those ingredients that have been seen to cause dispensing problems in detergents. WO95 / 06706 describes spray dried particles comprising alkylsulfates and lamellar silicates
crystalline

The formation of these gels not only limits the supply of the gelling ingredients to the wash but also of other detergent ingredients trapped in the gel. This results in an ineffective release of the detergent composition in all or part of it, thus reducing the capacity cleaner. Also, another problem associated with these certain ingredients that have a tendency to gel are that they can have tendency to form a cake, resulting in reduced capacity of product flow. In addition, the resulting waste in the washing machine and possibly even in tissues are undesirable, because they can lead to a dirty appearance of washing machines and clothes and even damage tissues.

Another problem associated with products detergents is that certain ingredients are not water soluble and tend to deposit in the tissues or in the washing machine, forming undesirable waste

The inventors have now discovered that when the surfactants are mixed intimately with a specific amount of laminar silicate type detergency reinforcing material crystalline by agglomeration, before its addition to the Detergent formulation, these problems improve. It has been found that crystalline laminar silicate levels and of intimately mixed surfactants are essential to improve these problems; for example, intimate mixtures comprising more than 60% of surfactant do not produce a satisfactory dispensing. The detergent compositions typically have a density apparent of at least 500 g / l.

It has been found that the use of surfactant intimately mixed crystalline laminar silicate, in agglomerates thereof, in solid detergent compositions, improves the dispensing of detergent compositions, or improves dissolution of detergent compositions or reduce gelation of detergent compositions in contact with water.

Summary of the invention

The invention provides a method to improve the dispensing of a detergent composition or component thereof, comprising a surfactant and other detergent components, providing a detergent composition comprising a mixture intimate of the surfactant component and a laminar silicate crystalline by agglomeration, not including agglomerates that comprise more than 60% surfactant.

In the use or method of the present invention, providing the surfactant or part thereof mixed intimately with a crystalline laminar silicate by agglomeration, it achieves an improvement in the dispensing of a detergent composition. By this it is meant that the dispensing of the composition detergent or component thereof in the wash water, including that of a dispenser drawer of a washing machine or a device dispenser, improves compared to detergent compositions that comprise the anionic surfactant not intimately mixed with a crystalline laminar silicate.

The improvement in dispensing may also include an improvement in the dissolution of a detergent composition or component of it in the wash water, including the water of wash in the dispenser drawer and wash water inside the washing machine, compared with detergent compositions comprising the anionic surfactant not intimately mixed with a silicate crystalline laminar.

The improvement of the composition dispensing detergent or component thereof may also include a reduction of waste deposition of the detergent composition or components thereof in wash fabrics or in the washing machine, in comparison with detergent compositions comprising the anionic surfactant not intimately mixed with a silicate crystalline laminar.

The improvement of the composition dispensing detergent or component thereof may also include a reduction of the gelation of the detergent composition or component in contact with water, especially at the beginning of washing process, in particular in the initial contact with water of the detergent composition in a dispenser drawer of a washing machine or inside the washing machine, compared with compositions detergents comprising the non-mixed anionic surfactant intimately with a crystalline laminar silicate.
