Title: Liquid detergent composition

Description:
FIELD OF THE INVENTION 
     The present invention relates to a hand dishwashing detergent composition comprising anionic surfactant, low-cut amine oxide and a cleaning amine. The composition provides improved cleaning and foaming properties and present good stability. 
     BACKGROUND OF THE INVENTION 
     Hand dishwashing detergent compositions should have a good suds profile while providing good soil and grease cleaning. However, a dichotomy exists between some cleaning technologies that are good for grease cleaning but impair on suds. 
     Users usually see foam as an indicator of the performance of the detergent composition. Moreover, the user of a hand dishwashing detergent composition also uses the sudsing profile and the appearance of the foam (density, whiteness) as an indicator that the wash solution or cleaning implement still contains active detergent ingredients. The user usually doses the dishwashing detergent depending on the foam ability and renews the wash solution when the suds subsides or when the foam does not look strong enough. Thus, a wash liquor comprising a dishwashing detergent composition that generates little foam would tend to be replaced by the user more frequently than it is necessary. Hand dishwashing detergent compositions need to provide good grease cleaning and to exhibit good foam height and appearance as well as good foam generation during the initial mixing of the detergent with water and good lasting foam during the entire manual dishwashing operation. 
     There is a need to provide hand dishwashing compositions with improved foam properties while at the same time providing improved grease cleaning.

The amine oxide surfactant can be a mixture of amine oxides comprising a low-cut amine oxide and a mid-cut amine oxide. 
     The low-cut amine oxide of the composition of the invention has the formula RaRbRcAO wherein Ra and Rb are independently selected from hydrogen, C1-C4 alkyls or mixtures thereof and wherein Rc is selected from C10 alkyls or mixtures thereof.

Compositions comprising RgRhRiAO tend to be unstable and do not provide very suds mileage. 
     The composition of the invention comprises anionic surfactant, the anionic surfactant can be any anionic cleaning surfactant, preferably the anionic surfactant comprises a sulphate anionic surfactant, more preferably an alkyl sulphate and/or alkoxylated sulfate anionic surfactant, preferably an alkyl alkoxylated sulphate, preferably the alkoxylated anionic surfactant has an average alkoxylation degree of from about 0.2 to about 3, preferably from about 0.2 to about 2, most preferably from about 0.2 to about 1.0.

Compositions in which the anionic surfactant and the amine oxide surfactant are in these ratios present very good cleaning and suds mileage. 
     Preferably, the composition of the invention comprises less than about 2%, more preferably less than 1% by weight of the composition of non-ionic surfactants. It has been found that the compositions with this low level of non-ionic surfactant can provide a more robust cleaning system. 
     According to the second aspect of the invention, there is provided a process for making the dishwashing detergent of the invention comprising a low-cut and a mid-cut amine oxide. The process requires the use of two different streams one comprising the low-cut amine oxide and another comprising the mid-cut amine oxide.

     The 1,3-diols of Formula (1) are synthesized as described in WO10026030, WO10026066, WO09138387, WO09153193, and WO10010075. Suitable 1,3-diols include 2,2-dimethyl-1,3-propane diol, 2-butyl-2-ethyl-1,3-propane diol, 2-pentyl-2-propyl-1,3-propane diol, 2-(2-methyl)butyl-2-propyl-1,3-propane diol, 2,2,4-trimethyl-1,3-propane diol, 2,2-diethyl-1,3-propane diol, 2-methyl-2-propyl-1,3-propane diol, 2-ethyl-1,3-hexane diol, 2-phenyl-2-methyl-1,3-propane diol, 2-methyl-1,3-propane diol, 2-ethyl-2-methyl-1,3 propane diol, 2,2-dibutyl-1,3-propane diol, 2,2-di(2-methylpropyl)-1,3-propane diol, 2-isopropyl-2-methyl-1,3-propane diol, or a mixture thereof. In some aspects, the 1,3-diol is selected from 2-butyl-2-ethyl-1,3-propanediol, 2-methyl-2-propyl-1,3-propanediol, 2-methyl-2-phenyl-1,3-propanediol, or a mixture thereof. Typically used 1,3-diols are 2-butyl-2-ethyl-1,3-propanediol, 2-methyl-2-propyl-1,3-propanediol, 2-methyl-2-phenyl-1,3-propanediol. 
     An alkoxylated 1,3-diol may be obtained by reacting a 1,3-diol of Formula I with an alkylene oxide, according to any number of general alkoxylation procedures known in the art. Suitable alkylene oxides include C 2 -C 18  alkylene oxides, such as ethylene oxide, propylene oxide, butylene oxide, pentene oxide, hexene oxide, decene oxide, dodecene oxide, or a mixture thereof. In some aspects, the C 2 -C 18  alkylene oxide is selected from ethylene oxide, propylene oxide, butylene oxide, or a mixture thereof. A 1,3-diol may be reacted with a single alkylene oxide or combinations of two or more different alkylene oxides. When using two or more different alkylene oxides, the resulting polymer may be obtained as a block-wise structure or a random structure. 
     Typically, the molar ratio of 1,3-diol to C 2 -C 18  alkylene oxide at which the alkoxylation reaction is carried out is in the range of about 1:2 to about 1:10, more typically about 1:3 to about 1:8, even more typically about 1:4 to about 1:6. 
     The alkoxylation reaction generally proceeds in the presence of a catalyst in an aqueous solution at a reaction temperature of from about 70° C. to about 200° C. and typically from about 80° C. to about 160° C. The reaction may proceed at a pressure of up to about 10 bar or up to about 8 bar. Examples of suitable catalysts include basic catalysts, such as alkali metal and alkaline earth metal hydroxides, e.g., sodium hydroxide, potassium hydroxide and calcium hydroxide, alkali metal alkoxides, in particular sodium and potassium C 1 -C 4 -alkoxides, e.g., sodium methoxide, sodium ethoxide and potassium tert-butoxide, alkali metal and alkaline earth metal hydrides, such as sodium hydride and calcium hydride, and alkali metal carbonates, such as sodium carbonate and potassium carbonate. In some aspects, the catalyst is an alkali metal hydroxides, typically potassium hydroxide or sodium hydroxide. Typical use amounts for the catalyst are from about 0.05 to about 10% by weight, in particular from about 0.1 to about 2% by weight, based on the total amount of 1,3-diol and alkylene oxide. 
     Alkoxylation with x+y C 2 -C 18  alkylene oxides and/or x 1 +y 1  C 2 -C 18  alkylene oxides produces structures as represented by Formula 2 and/or Formula 3: 
     
       
         
         
             
             
         
       
     
     where R 1 -R 12  are independently selected from H, alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl, where at least one of R 1 -R 6  and at least one of R 7 -R 12  is different from H, each of A 1 -A 9  is independently selected from linear or branched alkylenes having 2 to 18 carbon atoms, typically 2-10 carbon atoms, more typically 2-5 carbon atoms, and the sum of x+y is in the range of about 2 to about 200, typically about 2 to about 20, more typically about 2 to about 10 or about 2 to about 5, where x≧1 and y≧1, and the sum of x 1 +y 1  is in the range of about 2 to about 200, typically about 2 to about 20, more typically about 2 to about 10 or about 2 to about 5, where x 1 ≧1 and y 1 ≧1. 
     Step b): Amination 
     Amination of the alkoxylated 1,3-diols produces structures represented by Formula I or Formula II: 
     
       
         
         
             
             
         
       
     
     where each of R 1 -R 12  is independently selected from H, alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl, where at least one of R 1 -R 6  and at least one of R 7 -R 12  is different from H, each of A 1 -A 9  is independently selected from linear or branched alkylenes having 2 to 18 carbon atoms, typically 2-10 carbon atoms, more typically, 2-5 carbon atoms, each of Z 1 -Z 4  is independently selected from OH or NH 2 , where at least one of Z 1 -Z 2  and at least one of Z 3 -Z 4  is NH 2 , where the sum of x+y is in the range of about 2 to about 200, typically about 2 to about 20, more typically about 2 to about 10 or about 2 to about 5, where x≧1 and y≧1, and the sum of x 1 +y 1  is in the range of about 2 to about 200, typically about 2 to about 20, more typically about 2 to about 10 or about 2 to about 5, where x 1 ≧1 and y 1 ≧1. 
     Polyetheramines according to Formula I and/or Formula II are obtained by reductive amination of the alkoxylated 1,3-diol mixture (Formula 2 and Formula 3) with ammonia in the presence of hydrogen and a catalyst containing nickel. Suitable catalysts are described in WO 2011/067199A1, WO2011/067200A1, and EP0696572 B1. Preferred catalysts are supported copper-, nickel-, and cobalt-containing catalysts, where the catalytically active material of the catalyst, before the reduction thereof with hydrogen, comprises oxygen compounds of aluminum, copper, nickel, and cobalt, and, in the range of from about 0.2 to about 5.0% by weight of oxygen compounds, of tin, calculated as SnO. Other suitable catalysts are supported copper-, nickel-, and cobalt-containing catalysts, where the catalytically active material of the catalyst, before the reduction thereof with hydrogen, comprises oxygen compounds of aluminum, copper, nickel, cobalt and tin, and, in the range of from about 0.2 to about 5.0% by weight of oxygen compounds, of yttrium, lanthanum, cerium and/or hafnium, each calculated as Y 2 O 3 , La 2 O 3 , Ce 2 O 3  and Hf 2 O 3 , respectively. Another suitable catalyst is a zirconium, copper, and nickel catalyst, where the catalytically active composition comprises from about 20 to about 85% by weight of oxygen-containing zirconium compounds, calculated as ZrO 2 , from about 1 to about 30% by weight of oxygen-containing compounds of copper, calculated as CuO, from about 30 to about 70% by weight of oxygen-containing compounds of nickel, calculated as NiO, from about 0.1 to about 5% by weight of oxygen-containing compounds of aluminium and/or manganese, calculated as Al 2 O 3  and MnO 2  respectively. 
     For the reductive amination step, a supported as well as non-supported catalyst may be used. The supported catalyst is obtained, for example, by deposition of the metallic components of the catalyst compositions onto support materials known to those skilled in the art, using techniques which are well-known in the art, including without limitation, known forms of alumina, silica, charcoal, carbon, graphite, clays, mordenites; and molecular sieves, to provide supported catalysts as well. When the catalyst is supported, the support particles of the catalyst may have any geometric shape, for example spheres, tablets, or cylinders, in a regular or irregular version. The process may be carried out in a continuous or discontinuous mode, e.g. in an autoclave, tube reactor, or fixed-bed reactor. The feed thereto may be upflowing or downflowing, and design features in the reactor which optimize plug flow in the reactor may be employed. The degree of amination is from about 50% to about 100%, typically from about 60% to about 100%, and more typically from about 70% to about 100%. 
     The degree of amination is calculated from the total amine value (AZ) divided by sum of the total acetylables value (AC) and tertiary amine value (tert. AZ) multiplied by 100: (Total AZ: (AC+tert. AZ))×100). The total amine value (AZ) is determined according to DIN 16945. The total acetylables value (AC) is determined according to DIN 53240. The secondary and tertiary amines are determined according to ASTM D2074-07. 
     The hydroxyl value is calculated from (total acetylables value+tertiary amine value)−total amine value. The polyetheramines of the invention are effective for removal of greasy soils, in particular removal of crystalline grease.

     b) aminating the alkoxylated triol with ammonia. 
     This process is described in more detail below. 
     Alkoxylation 
     Polyetheramines according to Formula (III) may be obtained by reductive amination of an alkoxylated triol. Alkoxylated triols according to the present disclosure may be obtained by reaction of low-molecular-weight, organic triols, such as glycerine and/or 1,1,1-trimethylolpropane, with alkylene oxides according to general alkoxylation procedures known in the art. 
     By “low-molecular-weight,” it is meant that the triol has a molecular weight of from about 64 to about 500, or from about 64 to about 300, or from about 78 to about 200, or from about 92 to about 135 g/mol. The triol may be water soluble. 
     A low-molecular-weight, organic triol useful herein (or simply “low-molecular-weight triol,” as used herein) has the structure of Formula (4): 
     
       
         
         
             
             
         
       
     
     where R is selected from H or a C1-C6 alkyl group, and where each k is independently selected from 0, 1, 2, 3, 4, 5, or 6. Preferably, R is H or a C1-C6 alkyl group selected from methyl, ethyl, or propyl. More preferably, R is H or ethyl. k 1 , k 2 , and k 3  can each be independently selected from 0, 1, or 2.

     The alkoxylated triol, such as alkoxylated glycerine or alkoxylated 1,1,1-trimethylolpropane, may be prepared in a known manner by reaction of the low-molecular-weight triol with an alkylene oxide. Suitable alkylene oxides are linear or branched C 2 -C 18  alkylene oxides, typically C 2 -C 10  alkylene oxides, more typically C 2 -C 6  alkylene oxides or C 2 -C 4  alkylene oxides. Suitable alkylene oxides include ethylene oxide, propylene oxide, butylene oxide, pentene oxide, hexene oxide, decene oxide, and dodecene oxide.

In some aspects, the C 2 -C 18  alkylene oxide is butylene oxide, optionally in combination with other C 2 -C 18  alkylene oxides. 
     The low molecular weight triols, such as glycerine or 1,1,1-trimethylolpropane, may be reacted with one single type of alkylene oxide or combinations of two or more different types of alkylene oxides, e.g., ethylene oxide and propylene oxide. If two or more different types of alkylene oxides are used, the resulting alkoxylate may have a block-wise structure or a random structure. 
     Typically, the molar ratio of low-molecular-weight triol to C 2 -C 18  alkylene oxide at which the alkoxylation reaction is carried out is in the range of about 1:3 to about 1:10, more typically about 1:3 to about 1:6, even more typically about 1:4 to about 1:6. In some aspects, the molar ratio of low-molecular-weight triol to C 2 -C 18  alkylene oxide at which the alkoxylation reaction is carried out is in the range of about 1:5 to about 1:10. 
     When the low-molecular-weight triol is 1,1,1-trimethylolpropane, or when R of the triol of Formula (2) is a C2 alkyl and each of k 1 , k 2 , and k 3  are 1, the polyetheramine has a weight average molecular weight of from about 500 to about 1000, or to about 900, or to about 800 grams/mole. 
     The reaction is generally performed in the presence of a catalyst in an aqueous solution at a reaction temperature of from about 70° C. to about 200° C., and typically from about 80° C. to about 160° C. This reaction may be performed at a pressure of up to about 10 bar, or up to about 8 bar. 
     Examples of suitable catalysts are basic catalysts such as alkali metal and alkaline earth metal hydroxides, such as sodium hydroxide, potassium hydroxide and calcium hydroxide, alkali metal alkoxides, in particular sodium and potassium C 1 -C 4 -alkoxides, such as sodium methoxide, sodium ethoxide and potassium tert-butoxide, alkali metal and alkaline earth metal hydrides, such as sodium hydride and calcium hydride, and alkali metal carbonates, such as sodium carbonate and potassium carbonate. Alkali metal hydroxides, such as potassium hydroxide and sodium hydroxide, are particularly suitable. Typical use amounts for the basic catalyst are from about 0.05 to about 10% by weight, in particular from about 0.1 to about 2% by weight, based on the total amount of the low-molecular-weight triol and the alkylene oxide. 
     Amination 
     Polyetheramines according to Formula (III) may be obtained by reductive amination of an alkoxylated triol, such as those described above, for example alkoxylated glycerine or alkoxylated 1,1,1-trimethylolpropane, with ammonia in the presence of hydrogen and a catalyst, such as a catalyst containing nickel. Suitable catalysts are described in WO 2011/067199 A1, in WO2011/067200 A1, and in EP0696572 B1. 
     The amination may be carried out in the presence of copper-, nickel- or cobalt-containing catalyst. Preferred catalysts are supported copper-, nickel- and cobalt-containing catalysts, wherein the catalytically active material of the catalysts, before the reduction thereof with hydrogen, comprises oxygen compounds of aluminium, copper, nickel and cobalt, and, in the range of from about 0.2% to about 5.0% by weight, of oxygen compounds of tin, calculated as SnO. Other preferred catalysts are supported copper-, nickel- and cobalt-containing catalysts, wherein the catalytically active material of the catalysts, before the reduction thereof with hydrogen, comprises oxygen compounds of aluminium, copper, nickel, cobalt, tin, and, in the range of from about 0.2 to about 5.0% by weight, of oxygen compounds of yttrium, lanthanum, cerium and/or hafnium, each calculated as Y 2 O 3 , La 2 O 3 , Ce 2 O 3  and Hf 2 O 3 , respectively. Another suitable catalyst is a zirconium, copper, nickel catalyst, wherein the catalytically active composition comprises from about 20 to about 85% by weight of oxygen-containing zirconium compounds, calculated as ZrO 2 , from about 1 to about 30% by weight of oxygen-containing compounds of copper, calculated as CuO, from about 30 to about 70% by weight of oxygen-containing compounds of nickel, calculated as NiO, from about 0.1 to about 5% by weight of oxygen-containing compounds of aluminium and/or manganese, calculated as Al 2 O 3  and MnO 2 , respectively. 
     For the reductive amination step, a supported as well as a non-supported catalyst can be used. The supported catalyst may be obtained by deposition of the metallic components of the catalyst compositions onto support materials known to those skilled in the art, using techniques that are well-known in the art, including, without limitation, known forms of alumina, silica, charcoal, carbon, graphite, clays, mordenites; molecular sieves may be used to provide supported catalysts as well. When the catalyst is supported, the support particles of the catalyst may have any geometric shape, for example, the shape of spheres, tablets, or cylinders in a regular or irregular version. 
     The process can be carried out in a continuous or discontinuous mode, e.g., in an autoclave, tube reactor, or fixed-bed reactor. A number of reactor designs may be used. For example, the feed thereto may be upflowing or downflowing, and design features in the reactor that optimize plug flow in the reactor may be employed. 
     The degree of amination may be from about 67% to about 100%, or from about 85% to about 100%. The degree of amination is calculated from the total amine value (AZ) divided by sum of the total acetylables value (AC) and tertiary amine value (tert. AZ) multiplied by 100 (Total AZ/((AC+tert. AZ)×100)). 
     The total amine value (AZ) is determined according to DIN 16945. 
     The total acetylables value (AC) is determined according to DIN 53240. 
     The secondary and tertiary amines are determined according to ASTM D2074-07. 
     The hydroxyl value is calculated from (total acetylables value+tertiary amine value)−total amine value. 
     Amine of Formula (1): 
     The cleaning amine of Formula (1) has an ethylene diamine core with at least one primary amine functionality. The cleaning amine also comprises at least another nitrogen atom, preferable in the form of a tertiary amine functionality. Herein the term “core” refers to the alkyl chain between two nitrogen radicals. The number of carbons in the core does not include the radicals attached to the core. 
     The cleaning amine has the formula: 
     
       
         
         
             
             
         
       
     
     wherein: R 1 , R 2 , R 3 , R 4 , and R 5  are independently selected from —H, linear, branched or cyclic alkyl or alkenyl having from 1 to 10 carbon atoms and n=0-3. 
     Preferably, the cleaning amine is aliphatic in nature. The cleaning amine preferably has a molecular weight of less than about 1000 grams/mole and more preferably less than about 450 grams/mole. 
     “n” varies from 0 to not more than 3, preferably “n” is 0. The amine molecule contains at least one primary amine functionality and preferably a tertiary amine functionality. 
     Suitable cleaning amines for use herein include amines wherein R 1  and R 2  are selected from isopropyl and butyl, preferably R 1  and R 2  are both isopropyl or both butyl. 
     Preferably cleaning amines include those in which R1 and R2 are isopropyl and preferably, n is 0. Also preferred are amines in which R1 and R2 are butyl and preferably, n is 0

     Method of Washing 
     Other aspects of the invention are directed to a method of washing dishware with the composition of the present invention. 
     The composition herein can be applied in its diluted form. Soiled dishes are contacted with an effective amount, typically from about 0.5 ml to about 20 ml (per about 25 dishes being treated), preferably from about 3 ml to about 10 ml, of the detergent composition, preferably in liquid form, of the present invention diluted in water. The actual amount of detergent composition used will be based on the judgment of user, and will typically depend upon factors such as the particular product formulation of the composition, including the concentration of active ingredients in the composition, the number of soiled dishes to be cleaned, the degree of soiling on the dishes, and the like. Generally, from about 0.01 ml to about 150 ml, preferably from about 3 ml to about 40 ml of a liquid detergent composition of the invention is combined with from about 2000 ml to about 20000 ml, more typically from about 5000 ml to about 15000 ml of water in a sink having a volumetric capacity in the range of from about 1000 ml to about 20000 ml, more typically from about 5000 ml to about 15000 ml. The soiled dishes are immersed in the sink containing the diluted compositions then obtained, where contacting the soiled surface of the dish with a cloth, sponge, or similar article cleans them. The cloth, sponge, or similar article may be immersed in the detergent composition and water mixture prior to being contacted with the dish surface, and is typically contacted with the dish surface for a period of time ranged from about 1 to about 10 seconds, although the actual time will vary with each application and user. The contacting of cloth, sponge, or similar article to the dish surface is preferably accompanied by a concurrent scrubbing of the dish surface. 
     Another method may comprise immersing the soiled dishes into a water bath or held under running water without any liquid dishwashing detergent. A device for absorbing liquid dishwashing detergent, such as a sponge, is placed directly into contact with a separate quantity of undiluted liquid dishwashing composition for a period of time typically ranging from about 1 to about 5 seconds. The absorbing device, and consequently the undiluted liquid dishwashing composition, is then contacted individually to the surface of each of the soiled dishes to remove said soiling. The absorbing device is typically contacted with each dish surface for a period of time range from about 1 to about 10 seconds, although the actual time of application will be dependent upon factors such as the degree of soiling of the dish. The contacting of the absorbing device to the dish surface is preferably accompanied by concurrent scrubbing. 
     Alternatively, the device may be immersed in a mixture of the hand dishwashing composition and water prior to being contacted with the dish surface, the concentrated solution is made by diluting the hand dishwashing composition with water in a small container that can accommodate the cleaning device at weight ratios ranging from about 95:5 to about 5:95, preferably about 80:20 to about 20:80 and more preferably about 70:30 to about 30:70, respectively, of hand dishwashing liquid:water respectively depending upon the user habits and the cleaning task.
