Description

DETERGENT COMPOSITIONS FIELD OF THE INVENTION This invention relates to the washing of dirty articles. It is particularly applicable to hand-wash applications and to be used in combination with a hand-held container.

BACKGROUND OF THE INVENTION For many years, the hand-laundry industry has focused on solid detergent compositions which, when dissolved in a water solution, exhibit a low viscosity (eg, less than 15 mPas) because the low viscosity improves the distribution of the solid detergent composition, when dissolved in a water solution, during the washing process. To improve the cleaning performance of hand-washing detergent compositions, in particular during the hand washing of severely stained articles, the Applicant (Assignee) developed hand-held containers to be used in combination with these solid detergent compositions, as described in WO98 / 16438 and W098 / 16622. These hand-held containers improve the cleaning performance of solid detergent compositions provide distribution and friction means to assist in the procedure of severely stained articles. However, the inventors have found that the dwell time of the detergent in the residual stains is not long enough to provide optimal cleaning results, hence the cleaning performance of the solid detergent compositions, when used with a container of detergent. hand, is still not satisfactory. The inventors have also found that, in order to obtain a satisfactory cleaning performance, the consumer must use a large amount of the composition. However, this washing method is very inefficient and causes an extremely high consumption of the detergent product. The inventors have discovered that by adding a thickening agent to a solid detergent composition, said solid detergent composition can be used with a handheld container at a much lower concentration and achieve good cleaning results. The presence of a thickening agent is a solid detergent composition for use in combination with a hand-held container, it is a highly efficient washing process which results in a much lower consumption of the product than that previously achieved. When a solid detergent composition containing a thickening agent is in solution, the thickening agent increases the viscosity of said solution so that an optimum viscosity is reached at a much lower concentration of the solution. detergent, in particular because the viscous composition remains in the spots for sufficient time to provide good cleaning. This avoids the need to use a high detergent concentration to achieve this optimum viscosity. In addition, the performance of the distribution of a solid detergent composition comprising a thickening agent when in solution from a handheld container was surprisingly improved. This is due to the higher viscosity of said solution in the hand container that remains in the hand container and does not spill when the consumer uses said hand container to apply friction means to a severely stained article. Therefore, the purpose of the present invention is to provide a solid detergent composition which can be used at low concentrations in combination with a hand-held container, but where the viscosity is such that the residence time of the detergent in the residual stains is sufficiently long to achieve good cleaning results, thereby improving the efficiency of the washing process by reducing the consumption level of the detergent product during the washing process.
