Consumers that use liquid detergent as a mild liquid detergent composition for washing dishes, tend to laundering fat, difficulties in cleaning up things at the end of the wash, greater ease in cleaning items, such as glasses and Cutlery. Light liquid detergent compositions for washing dishes require a high profile foam while ensuring the removal of grease.

The recent trend has been the development of compositions for washing dishes by hand, which provide effective cleaning, as well as some benefits for the care of hands. For example, Henkel WO 2007/028571 describes liquid water cleaning products for hard surfaces, in particular for washing dishes by hand, containing an active substance with a beneficial effect in terms of the sensations of the skin, which can be select the but of the touch active substances and/or active substances with a positive biological effect. Lion JP 2005-179438 describes liquid detergent composition for the kitchen, which reduces problems with the skin, caused by detergents, prevents hardening of the skin and keeps the skin in a fresh condition by using plant extracts, a polyhydric alcohol and a surfactant.

The aim of the present invention is to provide compounds, which are still very effective for the removal of grease while providing excellent soft hands. It was found that the system specific anionic surfactants in accordance with the present invention will provide excellent cleaning required from the liquid composition for washing dishes by hand, being very soft and gentle to the hands. Additionally it was found that the pearlescent agent in accordance with the present invention, such as having a lamellar structure, for example, mica, will give benefits for the skin by affecting the correction of skin color and correction of skin luster. Interaction with light, provided pearlescent agent, contributes to the correction of the color and Shine of the skin by regulating the reflective properties of the skin. Therefore, it was found that the combination of pearlescent agent and system specific anionic surfactants in accordance with the present invention PR is the advantage of excellent treatments for the hands together with excellent cleaning from fat.

Another advantage of the composition in accordance with the present invention is to provide a user of such a product that will actually provide the intended benefits for the care of hands. Add pearlescent agent is in fact to provide excellent aesthetic properties, which will provide the consumer with the advantages of excellent softness of the skin. The rheology modifier in accordance with the present invention is to provide a very stable suspension of pearlescent agent and thus to improve the aesthetic properties of the product.

Lewis Soil (containing 12.7% of oil Crisco, 27.8% of fat Crisco, 7.6% of fat, which is 51.7% refined edible edible solid fat beef, 0.14% of oleic acid, 0.04% of palmitic acid and 0.02% stearic acid, supplied by J&R Coordinating Services, Ohio) is added to the test solution is again stirred, and the resulting foam height is measured again. A higher number of cycles contamination typically add up to achieve the minimum height of the foam, typically 0.5 to see the Number of cycles contamination is an indicator of the usefulness of foam (more cycles pollution, indicates the great value of foaming). This test can be used to simulate the initial profile of the foaming composition, as well as his profile foaming during application, with a larger introduction of contaminants on the surface being washed.

The profile analysis of foaming is as follows:

1. Prepare a set of clean, dry, calibrated cylinders, and water with a water hardness of 30 grams per gallon at a temperature of 40°C and at a concentration of active surfactant component of 0.03% by mass.
