The technical FIELD
The present invention relates to a liquid composition for washing dishes by hand and to a method of washing tableware in such detergent composition containing a chelating agent and a surfactant with an average degree of branching of at least 10%, to ensure superior cleaning action and Shine.
Optimization of purification from fatty substances is an ongoing challenge in the field of washing dishes by hand. Consumers using liquid detergent as a liquid detergent composition for washing lightly polluted dishes, usually wash oily, trudnosmyvaemye items last, after cleaning more easily otbivalsya items such as glasses and Cutlery. The liquid detergent compositions for washing lightly polluted cookware should have a high foaming capacity, while ensuring the removal of grease.
To ensure the removal of grease and foam requires a minimum amount of surfactant when used in pure or diluted form. However, the surfactant may leave a visible film and to form stripes and spots on the surface of the washed tableware. Shine, however, is also critical for consumers effect. Unexpectedly would is about detected, what superior Shine is achieved by using a combination of chelating agent with the developed system of surface-active substances, such as having an average degree of branching of the alkyl chain system surfactants in General, equal to at least 10%.
The aim of the present invention is to provide compositions for washing dishes by hand, providing superior detergency and Shine.
This invention relates to a liquid cleaning composition for washing dishes by hand, containing:
(a) from 0.1% to 20%, by weight of the composition as a whole, chelating agent,
(b) from 5% to 80%, by weight of the composition in General, surface-active substances selected from the group consisting of anionic, nonionic, cationic, amphoteric, zwitterionic, polupryamykh nonionic surfactants and mixtures thereof; where the average degree of branching of the alkyl chain of the surfactants is at least 10% of the total weight of surface-active substances.
The present invention additionally relates to a method of washing tableware in such liquid detergent composition.
A DETAILED DESCRIPTION of the INVENTION
Liquid detergent composition for washing dishes by hand method and the method of cleaning tableware according to the present invention unexpectedly on the provide a nice clean fat in combination with a beautiful Shine.
Used here meaning "fatty substance" means material that contains at least a portion (i.e., at least 0.5 percent by weight. from weight fatty substances) saturated and unsaturated fats and oils, preferably, oils and fats derived from animal sources such as beef and/or chicken.
Used here the value of "foaming ability (suds profile) means the amount of foam (high or low) and the resistance (resistant foam), foam, resulting from the use of the liquid detergent composition of the present invention in the process of washing. Used here the value "high foaming" refers to liquid detergent compositions for washing dishes by hand, with high foaming ability (i.e. level of foaming, which is considered acceptable for consumers) and stable foaming (i.e. high level of foaming is maintained during operation of the washing up). This is especially important for liquid detergent compositions for washing dishes, because the consumer uses high foaming as an indicator of working caracteristic detergent composition. In addition, the consumer liquid detergent composition for washing dishes uses foaming ability as an indicator that the cleaning solution still contains active in redient detergent. The consumer typically updates the cleaning solution when the foaming stops. Thus, the consumer will seek to replace the liquid detergent composition for washing low foaming more than necessary, due to the low level of foaming.
Used here the value of "tableware" means a surface, such as plates, glasses, pots, pans, bakeware and Cutlery made from ceramic, porcelain, metal, glass, plastic (polyethylene, polypropylene, polystyrene etc) and wood.
Used here the value of "liquid detergent composition for washing dishes by hand" refers to the compositions used for the manual (i.e. hand) dishwashing. Such compositions are typically characterized by strong foaming or foaming in nature.
Used here to mean "clearing" means the application of the surface for cleaning and/or disinfection.

The compositions of the present invention provide improved cleaning uluchshenie Shine. Effective cleaning active substances such as anionic surfactants based on alkyl sulphates and alkylbenzenesulfonates lead to deposition on the surfaces of the crystalline material, giving them a dull appearance, and/or leave a film, stripes and spots. This is because the cleaning active substances form insoluble salts with ions of Ca/Mg present in the water. It was found that the chelating agents capable of inhibiting the growth of crystals, will prevent the formation of crystals, especially in the presence of impurities, and therefore will provide luster washed tableware. Unexpectedly, it was further discovered that the combination of chelating agents and systems of surface-active substances, characterized by an average degree of branching of the alkyl chain of at least 10% of the system surface-active substances in General, provides a superior Shine. Without wanting to be limited by theory indicate that, as is the combination of chelating agents branched surfactants provides superior cleaning (clarification) from the film by means of destruction and prevent the formation of crystalline films created resulting salts, and additionally improves the wetting of the surface. In total, combine the Oia chelating agent and system branched surfactants will effectively prevent the formation of crystalline films on the surface of the ware and to provide improved wetting and thus, superior Shine.

Chelating agents are chemical compounds that form soluble, complex molecules with certain metal ions, inactivating these ions so that they cannot normally react with other elements or ions with the formation of sludge or scum. The ligand forms a chelate complex with the substrate. This term is used to complexes in which the metal ion is associated with two or more atoms of a chelating agent.
