The technical field to which the invention relates

The present invention relates to a method of washing dishes manually by applying undiluted liquid detergent composition directly on the dishes or with a sponge. Because of the presence of branched ethoxylated nonionic surfactant in liquid detergent compositions provide effective cleaning from grease with persistent foam, during long-term use in the methods of direct application.

The level of technology

While some consumers prefer to wash dishes, dipping it in dilute liquid detergent compositions, many consumers prefer to apply undiluted liquid detergent composition directly on the dishes or using tools, such as a sponge. Applied direct provides enhanced cleaning of grease, since a large concentration of surfactant is applied directly on the stain. For direct ways of drawing consumers want sustainable in a long time cleaning from grease and sustainable for a long time foam. Previously, such "working time" was continued by increasing the level of surfactant. However, while this increased level surface�IDT-active substances actually improves the profile for the diluted foaming liquid detergent composition, a higher level of surfactants leads to deterioration of the original foaming during washing dishes by direct application. Additionally, such liquid detergent compositions are less desirable fatty and viscous appearance.

There is therefore a need in the way of washing dishes manually by direct application easy wash liquid detergent composition, resulting in superior cleaning from grease, excellent original foaming and stable in a long time pen.

It has surprisingly been found that liquid compositions of detergents for washing dishes by hand, containing even small amounts of branched alkoxyimino nonionic surfactant that provides superior sustained for a long period of time the foam and excellent cleaning of grease, when used in the methods of direct application, being at the same time is easily washable.

WO 9533025, US 5968888, US 2005/0170990 A1 describe methods of washing dishes by hand, including the stage of contacting the dishware with a liquid detergent composition in undiluted form. US 2007/0123447 A1, WO 2006/041740 A1, US 6,008,181 describe compositions for washing dishes containing branched surfactants.

Summary of the invention

In accordance with the present invention presents a method of washing dishes by hand using liquid detergent compositions containing from 0.1 to 5% by weight alkoxysilane branched nonionic surfactant, having an average degree of alkoxysilane from 1 to 40; wherein the method comprises a stage on which is injected into contact a liquid detergent composition in its neat form with the dishes. The present invention is also the use of liquid detergent compositions containing from 0.1 to 5% by weight alkoxysilane branched nonionic surfactant, having an average degree of alkoxysilane from 1 to 40; to ensure sustainable in the long profile of the foam in the ways of washing dishes manually by direct application.

Detailed description of the invention

As used in this application, "liquid detergent composition for washing dishes by hand" refers to those compositions that are used in manually (i.e. by hand) cleaning of utensils. Such compositions in General have a high foaming or foam by nature. As used in this application, the "cleaning" means the application of a liquid detergent composition for washing dishes by hand on a surface to remove undesired hair�th residue, such as pollution, grease, stains, and/or for disinfection.

As used in this application, "tableware" means a surface such as dishes, glasses, pots, pans, kitchenware, bakeware and Cutlery, made of ceramic, porcelain, metal, glass, plastic (polyethylene, polypropylene, polystyrene, etc.) and wood.

As used in this application, the "grease" means materials containing at least partially (i.e. at least 0.5 wt.% by weight of the grease) saturated and unsaturated fats and oils, preferably oils and fats derived from animal sources such as beef and/or chicken.

As used in this application, profile foam" means a foam (high or low) and duration of flushing (how sustainable or long-term is the foam during the wash process, resulting from the use of liquid detergent compositions. As used in this application, "high foaming" or "stable for a long time foam" refers to liquid detergent compositions for washing dishes manually, which generates high levels of foam (i.e., the level of foaming is considered acceptable to the consumer) and where the level of stable foam during the operation of washing dishes. This is particularly important in relation to the Jew�their compositions of detergents for washing dishes, since the consumer perceives high foaming in the performance of the detergent composition. Additionally, the user also uses the profile of foaming as an indication that the cleaning solution still contains active ingredients of detergents. The consumer typically causes additional liquid detergent composition for washing dishes by hand, when the foam subsides. Thus, the detergent composition for washing dishes low foaming will tend to be used by the user more than necessary.

The term "in its undiluted form" in this application mean that the specified composition is applied directly onto the surface or on the device or the cleaning tool, such as brush, sponge, nonwoven fabric, or woven material, without any significant dilution by the user (immediately) before applying. "In its undiluted form, also includes a small breeding, for example, arising from the presence of water in the cleaning device, or the addition of water to the consumer to remove the remaining amount of the composition from the bottle. Therefore, the composition in its neat form includes a mixture comprising the composition and water in ratios ranging from 50:50 to 100:0, pre�occhialino from 70:30 to 100:0, more preferably from 80:20 to 100:0, even more preferably from 90:10 to 100:0 depending on user habits and clean-up tasks. For the avoidance of doubt the ratio of 100:0 is the most preferred.

The term "diluted form" in this application mean that the specified composition is diluted by the user, typically water. The term "rinse" in this application involve contacting the tableware, which is purified composition with a substantial amount of water after the step of applying a liquid composition on a specified dishes.

The term "significant amount" shall mean generally from 1 to 20 liters.

All percentages, ratios and proportions used in this application, is given as a mass percentage of liquid detergent compositions for washing dishes manually. All average values are calculated "by weight" liquid detergent compositions for washing dishes manually, unless specifically stated otherwise.

Liquid detergent compositions for washing dishes manually and can be used for washing dishes in a variety of ways, depending on the level and type of contamination or grease, and consumer preferences.

The present invention provides a method of applying undiluted liquid detergent compositions�of funds includes a stage on which is brought into contact this composition, in its undiluted form with the dishes. Said composition can be poured directly onto the plate from the container. Alternatively, the composition may be deposited on the device or the cleaning device, for example a brush, sponge, non-woven material or woven material. The apparatus or means of purification, and therefore the liquid composition for washing dishes in its undiluted form, then in direct contact with each contaminated surface of the dish to remove specified impurities. The device or the cleaning tool is typically in contact with each surface of the dish during the time period in the range from 1 to 10 seconds, although the actual time of application will depend on such factors as the degree of soiling of the dish. Contacting said device or means of cleaning the surface of the dish is preferably accompanied by simultaneous scraped. Alternatively, the apparatus or means may be immersed in a liquid detergent composition for washing dishes by hand in its undiluted form, in a small container that can hold a cleaning device.

Before applying the specified song, contaminated glassware can be immersed in a water bath, or hold it under running water, to soak in�arnosti ware.

The method may include an optional rinsing stage, after the step of contacting a liquid detergent composition with the dishes.

The present invention is also the use of liquid detergent compositions containing from 0.1 to 5% by weight of a branched nonionic surfactant, having an average degree of alkoxysilane from 1 to 40, to ensure sustainable in the long profile of the foam in the ways of washing dishes manually by direct application.

That is, the liquid detergent composition has a turbidity of 5 NTU to less than 3000 NTU, preferably less than 1000 NTU, more preferably less than 500 NTU and most preferably less than 100 NTU.

Alkoxysilane branched non-ionic surfactant

Liquid detergent compositions for washing dishes manually, which are used in the method according to the present invention contain from 0.1% to 5%, preferably from 0.2% to 3%, more preferably from 0.5% to 2% by weight alkoxysilane branched nonionic surfactant. Specified alkoxysilane branched non-ionic surfactant has an average degree of alkoxysilane from 1 to 40, preferably from 3 to 20, more preferably from 7 to 12. The average degree of alkoxysilane is defined as the average number of moles of alkylated per mole alkoxysilanes branched non-ionic surfactant in accordance with the present invention. Preferably the branched non-ionic substance is an ethoxylated and/or propoxycarbonyl, more preferably ethoxylated.

N�ethoxylated branched non-ionic surfactant in combination with ethoxylated anionic surface-active substance in these compositions, it has been found that limiting characteristic of the foaming liquid detergent composition. Therefore, the composition preferably contains less than 10%, more preferably less than 5%, most preferably less than 2% by weight neilcicierega branched alcohol. To surfactant was acceptable surfactant, branched nonionic surfactant preferably contains from 8 to 24, more preferably from 9 to 18, most preferably 10 to 14 carbon atoms. Alkoxysilane branched nonionic alcohols selected from: formula I, formula II, and mixtures thereof, are particularly preferred:

The degree of alkoxysilane specified branched nonionic substance is preferably greater than the degree of amoxilonline ethoxylated anionic surfactant, in the presence. With increase in the degree of amoxilonline anionic surfactant increases the viscosity of the liquid detergent compositions for washing dishes manually. Believe that this is because the hydrophilicity of the overall system of the surfactant increases. Additionally, liquid compositions of detergents for washing dishes by hand in General is obtained using premix of surfactants. With increase in the degree of amoxilonline anionic surfactants, the probability of such gelation of the premix of surfactants during processing increases. However, it has been discovered that by incorporating small amounts of branched nonionic surfactant, having a higher degree of alkoxysilane than the degree of amoxilonline anionic surfactants, the viscosity of the premix surface-aktivno� substances and the resulting composition can be controlled.

Alkoxysilane branched nonionic surfactants can be classified as relatively water-insoluble or relatively water-soluble.

The average degree of amoxilonline is defined as the average number of moles of ethylene oxide per mole of ethoxylated anionic surfactants in accordance with the present Fig�taniam. If used, ethoxylated anionic surfactant derived from fatty alcohol, where at least 80%, preferably at least 82%, more preferably at least 85%, most preferably at least 90% by weight of the specified fatty alcohol are linear. The term "linear" means that the fatty alcohol contains one skeleton carbon atoms with no branching.

Acceptable ethoxylated alkylsulfate surfactants include saturated C8-C16Ala�lexicality, preferably a saturated C12-C14alkylalkoxysilane.

The ratio R1,which is linear, is such that at least 80% by weight of the original fatty alcohol are linear. Saturated alkyl chain is preferred, as the presence of double bonds may lead to chemical reactions with other ingredients, such as some of the ingredients of fragrances, or even with UV radiation. Such reactions can lead to instability of the phases, change in color and odor.

The required distribution of carbon chain length can be obtained by using alcohols with the corresponding distribution of the chain length, obtained synthetically or from natural raw materials or the respective pure compounds. Preferably, the anionic surfactant according to the present invention is obtained from the alcohol of natural origin. Natural sources such as plant or animal esters (waxes), can be obtained by obtaining linear alcohols with terminal primary hydroxyl group, along with varying degrees of unsaturation. Such fatty alcohols containing alkyl chain in the range of C8to C16can be obtained by any known commercial process, such as obtaining fatty alcohols from JI�tion of acids or methyl esters, and sometimes triglycerides. For example, the addition of hydrogen in the carboxyl group of the fatty acid to obtain fatty alcohol, when treated with hydrogen at high pressure and in the presence of acceptable metal catalysts. For similar reactions, fatty alcohols can be obtained by hydrogenation of glycerides or methyl esters. The recovery of methyl esters is an acceptable means of providing saturated fatty alcohols, and selective hydrogenation with the use of special catalysts such as the oxides of copper or cadmium, may be used to obtain olejowego alcohol. Synthetic processes or processes petroleum-based, such as the Ziegler process, are useful for obtaining an acceptable unbranched, containing even number of atoms, saturated alcohols. Oxidation of paraffins is an acceptable method to obtain the mixed primary alcohols. Fatty alcohol can react with the ethylene oxide with obtaining ethoxylated fatty alcohols. Ethoxylated alkylsulfate surface-active substance(substances) of the formula R1-(Och2CH2)nOh-SO3-M+can then be obtained by sulfonation of the corresponding ethoxylated fatty alcohol(alcohols).

Coconut oil typically contains triglycerides that can be chemically processed to produce a mixture of C12-C18alcohols. A mixture of alkylsulfates containing a high proportion of C12-C14alkylsulfates may be obtained by separation of the corresponding alcohols in front of the stage amoxilonline or sulfation or obtained by separating the ethoxylated alcohol or ethoxylated alkylsulfate surface-active substance(substances).

If desired, such surfactants may include linear alkyl fragments derived from synthetic sources, or may contain a mixture likelikelikelikelike of alkylsulfates with slightly branched, for example, methyl branched counterparts. Ethoxylated alkylsulfate can be in the form of their salts of sodium, potassium, ammonium or alkanolamine salts. Acceptable alcohol precursors for ethoxylated anionic surfactants include obtained by the Ziegler process linear alcohols, the alcohols obtained by the hydrogenation of Oleochemicals, and 80% or more of linear alcohols obtained by the enrichment of the linear component oxo derived alcohols, such as Neodol® or Dobanol® from Shell.

Cationic polymers

In a preferred implementation, the liquid composition for washing dishes by hand in the d�the auditors request may contain, at least one cationic polymer. Without wanting to be bound by theory, believe that the interaction of cationic polymer with anionic surface-active substance leads to the phenomenon of the separation of phases, known as coacervate where the polymer-enriched koatservatnyh phase is separated from the bulk phase composition. Koatservatsija increases the deposition of cationic polymer on the skin and facilitates the deposition of other active agents, such as hydrophobic emollient materials who can get into such koatservatnyh phase and as such jointly deposited on the skin. This koatservatnyh phase can exist in a liquid detergent for washing dishes manually or alternatively may be formed after dilution or rinsing the cleaning composition.

The cationic polymer will typically be present at a level from 0.001% to 10%, preferably from 0.01% to 5%, more preferably from 0.05% to 1% by weight of the whole composition.

The charge density is calculated by dividing the total number of charges in a recurring segment on the molecular weight of the repetitive unit. Positive charges can be located on the frame of the polymers and/or side chains of polymers. In General, regulation of ratios of amine fragments or fragments of Quaternary ammonium in the polymer depending on the pH of the liquid composition for washing dishes in the case of amines will affect the charge density. Any anionic counterions can be used in combination with a cationic deposition polymers as long as the polymer remains soluble in water and in the composition according to the present invention, and while the counterion is physically and chemically stable with essential components of the composition, or not too impair product performance, stability or aesthetic quality.
