Description:
FIELD OF THE INVENTION 
       [0001]    The present invention generally relates to cosmetics, and further relates to the use of the cleansing agents for improving detanglability and combability, in particular of damaged hair, and for reducing the static charge of hair and the development of shaggy or undesirably frizzy hair. 
       BACKGROUND OF THE INVENTION 
       [0002]    The structure of hair can be damaged as a result of environmental factors (such as intensive solar radiation), mechanical stresses (such as intensive combing while applying heat from a hair dryer), or physical or chemical treatments (such as dying, reshaping or straightening the hair). The consequences are often times split ends, hair breakage and/or lack of luster. Damaged hair moreover is difficult to detangle and style. 
         [0003]    Hair cleansing agents generally comprise (anionic) surfactants. These are desirable and necessary to be able to remove sebum and other dirt deposits from the surface of the hair and the scalp. However, they also cause lipids and proteins to be removed from the hair or the scalp during cleansing, so that a subsequent treatment with nourishing agents for regenerating the hair is necessary. 
         [0004]    Cleansing hair that has already become damaged is therefore problematic, and a need exists for particularly mild hair cleansing agents that do not place an additional burden on the damaged hair during cleansing and nourish the hair. 
         [0005]    The formulation of so-called conditioning hair cleansing agents is known. EP 1329215, for example, proposes nourishing hair cleansing compositions that, when diluted 20-fold, have a pH value in the range of 1 to 4 and comprise an anionic sulfate surfactant, a cationic guar gum, a hydroxycarboxylic acid (glycolic acid, lactic acid or malic acid) and a salt (in particular inorganic or organic sodium salts). The hair cleansing agents exhibit particularly good foaming properties and impart more softness, luster and suppleness to hair cleansed therewith. 
         [0006]    This technique, however, is not useful, especially when treating damaged hair and/or a dry scalp, since the high acidity of the agents can additionally cause the scalp to dry out and result in undesirable dandruff formation. Moreover, the ability to detangle in particular long, damaged hair was not satisfactory after the treatment with the agents. 
         [0007]    A continued need therefore exists for mild hair cleansing agents that are gentle on the scalp and that in particular are suitable for cleansing damaged hair and imparting advantageous visual and haptic properties. 
         [0008]    It is therefore desirable to provide mild, nourishing hair cleansing agents that are tolerated well by the skin and hair and mitigate hair damage. In particular long, damaged hair is to be strengthened in terms of the structure thereof during cleansing and should be easily detangled after cleansing. 
         [0009]    Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with this background of the invention. 
       BRIEF SUMMARY OF THE INVENTION 
       [0010]    A hair cleansing agent includes, based on the weight thereof: 6 to 12 wt. % of at least one anionic surfactant; 0.1 to 5 wt. % of at least one non-ionic surfactant; 0.01 to 2 wt. % of at least one cationic nourishing polymer; and (i) 0.01 to 3 wt. % calcium lactate or (ii) 0.1 to 5 wt. % lactic acid and 0.05 to 3 wt. % of at least one inorganic calcium salt, characterized in that the hair cleansing agent has a pH value in the range of 4.3 to 5.0. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0011]    The present invention will hereinafter be described in conjunction with the following drawing figures, wherein like numerals denote like elements, and 
           [0012]      FIG. 1  is a graph depicting comparative data for wet and dry hair properties following treatment with compositions according to the present invention and also comparative compositions. 
       
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0013]    The following detailed description of the invention is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description of the invention. 
         [0014]    It was found that the skin tolerability and mild nature of nourishing hair cleansing agents can be significantly increased if these comprise a mixture of mild anionic and non-ionic surfactants, cationic polymers, and a special salt (or a special acid/salt mixture) and have a slightly acidic pH value. 
         [0015]    A first subject matter of the invention is a hair cleansing agent that, based on the total weight thereof, comprises
       a) 6 to 12 wt. % of at least one anionic surfactant;   b) 0.1 to 5 wt. % of at least one non-ionic surfactant;   c) 0.01 to 2 wt. % of at least one cationic nourishing polymer; and   d) (i) 0.01 to 3 wt. % calcium lactate or
           (ii) 0.1 to 5 wt. % lactic acid and 0.05 to 3 wt. % of at least one inorganic calcium salt,
 
and has a pH value in the range of 4.3 to 5.0.
   
               
 
         [0021]    The hair cleansing agents according to the invention have a number of advantages: they are especially mild and do not burden or damage the (dry) scalp. Moreover, they impart improved detanglability and combability to the hair treated therewith, both when wet and when dry, and reduce the static charge and “fly-away” of hair as well as the development of shaggy or undesirably frizzy hair (“anti-frizz effect”). 
         [0022]    The hair cleansing agents according to the invention preferably comprise the active ingredient combination a) to d) in a cosmetically acceptable carrier. A cosmetically acceptable carrier within the scope of the invention shall preferably be understood to mean an aqueous or aqueous-alcoholic carrier. Particularly preferably, the cosmetic carrier includes at least 50 wt. %, more preferably at least 60 wt. %, and particularly preferably at least 65 wt. % water. 
         [0023]    The cosmetic carrier can moreover include 0.01 to 40 wt. %/o, preferably 0.05 to 30 wt. %, and in particular 0.1 to 20 wt. % of at least one alcohol, which can be selected from ethanol, ethyl diglycol, 1-propanol, 2-propanol, isopropanol, 1,2-propylene glycol, glycerol, diglycerol, triglycerol, 1-butanol, 2-butanol, 1,2-butanediol, 1,3-butanediol, 1-pentanol, 2-pentanol, 1,2-pentanediol, 1,5-pentanediol, 1-hexanol, 2-hexanol, 1,2-hexanediol, 1,6-hexandiol, polyethylene glycols, sorbitol, sorbitan, benzyl alcohol, phenoxyethanol or mixtures of these alcohols. The water-soluble alcohols are particularly preferred. In particular, ethanol, ethyl diglycol, 1-propanol, 2-propanol, isopropanol, 1,2-propylene glycol, glycerol, benzyl alcohol and/or phenoxyethanol and mixtures of these alcohols are preferred. 
         [0024]    Particularly mild hair cleansing agents having excellent nourishing properties for damaged hair were able to be produced in a narrower pH range. 
         [0025]    In a first preferred embodiment, the hair cleansing agents according to the invention thus have a pH value in the range of 4.4 to 5.0, more preferably of 4.5 to 4.9, and in particular of 4.5 to 4.8. 
         [0026]    The suitable anionic surfactants that can be used in the hair cleansing agents according to the invention include, for example:
       linear and branched fatty acids having 8 to 30 carbon atoms (soaps);   ether carboxylic acids of formula R—O—(CH 2 —CH 2 O) x —CH 2 —COOH, in which R is a linear or branched, saturated or unsaturated alkyl group having 8 to 30 carbon atoms, and x=0 or 1 to 16;   acyl sarcosides having 8 to 24 carbon atoms in the acyl group;   acyl taurides having 8 to 24 carbon atoms in the acyl group;   acyl isethionates having 8 to 24 carbon atoms in the acyl group;   sulfosuccinic acid monoalkyl and/or dialkyl esters having 8 to 24 carbon atoms in the alkyl group, and sulfosuccinic acid monoalkyl polyoxyethyl esters having 8 to 24 carbon atoms in the alkyl group and 1 to 6 oxyethyl groups;   alpha-olefin sulfonates having 8 to 24 carbon atoms;   alkyl sulfate and/or alkyl polyglycol ether sulfate salts of formula R—(O—CH 2 —CH 2 ) n —OSO 3 X, in which R is preferably a linear or branched, saturated or unsaturated alkyl group having 8 to 30 carbon atoms, x denotes the number 0 or 1 to 12, and X denotes an alkali, alkaline earth, ammonium or alkanolamine ion;   sulfonates of unsaturated fatty acids having 8 to 24 carbon atoms and 1 to 6 double bonds;   esters of tartaric acid and citric acid with alcohols that represent addition products of approximately 2 to 15 molecules ethylene oxide and/or propylene oxide to fatty alcohols having 8 to 22 carbon atoms; and/or   alkyl and/or alkenyl ether phosphates of formula       
 
         [0000]    
       
                 
         
             
             
         
       
       
         
           
             in which R 1  preferably denotes an aliphatic hydrocarbyl radical having 8 to 30 carbon atoms, R 2  denotes hydrogen, a (CH 2 CH 2 O) n R 1  group or X, n denotes numbers from 1 to 10, and X denotes hydrogen, an alkali metal or alkaline earth metal or the group NR 3 R 4 R 5 R 6 , where R 3  to R 6 , independently of one another, denote a C 1  to C 4  hydrocarbyl radical. 
           
         
       
     
         [0039]    Particularly preferred within the scope of the present invention are mild anionic surfactants that are gentle to the scalp, which within the scope of the present invention shall preferably be understood to include ether carboxylic acids, acyl isethionates, sulfosuccinic acid esters and alkyl (polyglycol ether) sulfates. 
         [0040]    In a second preferred embodiment, the hair cleansing agents according to the invention thus preferably comprise ether carboxylic acids of formula R—O—(CH 2 —CH 2 O) x —CH 2 —COOH as anionic surfactants, in which R denotes a linear or branched, saturated or unsaturated alkyl group having 8 to 30 carbon atoms, and x=0 or 1 to 16, acyl isethionates having 8 to 24 carbon atoms in the acyl group, sulfosuccinic acid monoalkyl and/or dialkyl esters having 8 to 24 carbon atoms in the alkyl group, and sulfosuccinic acid monoalkyl polyoxyethyl esters having 8 to 24 carbon atoms in the alkyl group and 1 to 6 oxyethyl groups and/or alkyl sulfate salts and/or alkyl polyglycol ether sulfate salts of formula R—(OCH 2 —CH 2 ) x —OSO 3- X + , in which R preferably denotes a linear or branched, saturated or unsaturated alkyl group having 8 to 30 carbon atoms, x denotes the number 0 or 1 to 12, and X +  denotes an alkali, alkaline earth, ammonium or alkanolamine ion. 
         [0041]    Especially particularly preferred are alkyl ether sulfate salts of formula R—(OCH 2 —CH 2 )—OSO 3- X + , in which R preferably denotes a straight-chain or branched alkyl group having 8 to 18, and in particular 10 to 16, carbon atoms, x denotes 1 to 6, and in particular 2 to 4, ethylene oxide units, and X +  denotes a sodium, magnesium and/or triethanolamine ion. In particular, the sodium, magnesium and/or triethanolamine salts of linear or branched lauryl, tridecyl and/or myristyl sulfates having a degree of ethoxylation of 2 to 4 are preferred, as they are commercially available, for example, under the INCI name Sodium Laureth Sulfate or Sodium Trideceth Sulfate. These surfactants have a particularly good balance between foamability and mildness. 
         [0042]    An excessively high content of anionic surfactants is not suitable for the mild hair cleansing agents according to the invention, and for this reason these comprise 6 to 12 wt. % of one or more anionic surfactants, based on the weight of the hair cleansing agents. In particular, the hair cleansing agents according to the invention preferably comprise alkyl sulfate salts and/or alkyl polyglycol ether sulfate salts of the aforementioned formula in amounts of 6 to 12 wt. %. 
         [0043]    A further preferred embodiment of the invention is thus characterized in that the hair cleansing agents, based on the total weight thereof, comprise 6 to 12 wt. %, preferably 7 to 11 wt %, and in particular 8 to 10 wt. % of at least one anionic alkyl ether sulfate salt of formula R—(OCH 2 —CH 2 ) x —OSO 3- X + , in which R denotes a straight-chain or branched alkyl group having 8 to 18, and in particular 10 to 16 carbon atoms, x denotes 1 to 6, and in particular 2 to 4 ethylene oxide units, and X +  denotes a sodium, magnesium and/or triethanolamine ion. 
         [0044]    So as to achieve optimal foaming properties and mildness at the same time, the hair cleansing agents according to the invention comprise 0.1 to 5 wt. % of at least one non-ionic surfactant, in addition to at least one anionic surfactant, based on the total weight of the agents. 
         [0045]    The non-ionic surfactants/emulsifiers that are suitable according to the invention preferably include:
       C 8  to C 30  fatty acid monoesters and diesters of addition products of 1 to 30 moles ethylene oxide to glycerol;   amine oxides;   addition products of 2 to 50 moles ethylene oxide and/or 0 to 5 moles propylene oxide to linear and branched fatty alcohols having 8 to 30 carbon atoms, to fatty acids having 8 to 30 carbon atoms, and to alkyl phenols having 8 to 15 carbon atoms in the alkyl group;   sorbitan fatty acid esters and addition products of ethylene oxide to sorbitan fatty acid esters, such as polysorbates;   sugar fatty acid esters and addition products of ethylene oxide to sugar fatty acid esters;   fatty acid alkanolamides of the general formula       
 
         [0000]    
       
                 
         
             
             
         
       
       
         
           
             in which R preferably denotes a linear or branched, saturated or unsaturated alkyl or alkenyl group having 8 to 24 carbon atoms, and the groups R 1  denote hydrogen or the group —(CH 2 ) n OH, in which n denotes the number 2 or 3, with the proviso that at least one of the groups R′ denotes the aforementioned group —(CH 2 ) n OH; 
             addition products of ethylene oxide to fatty amines and/or 
             alkyl oligoglucosides, and in particular alkyl oligoglucosides based on hydrogenated C 12/14  coconut alcohol having a DP of 1 to 3, as they are commercially available, for example, under the INCI name “Coco-Glucoside,” “Decyl Glucoside” and/or “Lauryl Glucoside.” 
           
         
       
     
         [0055]    The use of high-foaming and/or foam-stabilizing non-ionic, mild surfactants has proven to be extremely satisfactory, and for this reason, hair cleansing agents according to the invention in a third particularly preferred embodiment are characterized by comprising at least one non-ionic surfactant, selected from C 8  to C 30  fatty acid monoesters and/or diesters of addition products of 1 to 30 moles ethylene oxide to glycerol, addition products of 2 to 50 moles ethylene oxide and/or 0 to 5 moles propylene oxide to linear and branched fatty alcohols having 8 to 30 carbon atoms, fatty acid alkanolamides of the general formula 
         [0000]    
       
                 
         
             
             
         
       
     
         [0000]    in which R preferably denotes a linear or branched, saturated or unsaturated alkyl or alkenyl group having 8 to 24 carbon atoms, and the groups R′ denote hydrogen or the group —(CH 2 ) n OH, in which n denotes the number 2 or 3, with the proviso that at least one of the groups R′ denotes the aforementioned group —(CH 2 ) n OH, and/or alkyl polyglucosides. 
         [0056]    In addition to the mildness, fatty acid alkanolamides have foam-stabilizing, thickening and nourishing (lipid-replenishing) properties, and for this reason, hair cleansing agents according to the invention in a further advantageous embodiment that are particularly preferred are those that, based on the total weight thereof, comprise 0.1 to 5 wt. %, preferably 0.2 to 3 wt. %, and in particular 0.4 to 2 wt. % of at least one fatty acid alkanolamide of the aforementioned formula. In particular, a fatty acid alkanolamide known under the INCI name Cocamide MEA is preferred. 
         [0057]    In addition to the surfactant mixture of anionic and non-ionic surfactants in specific quantities, the hair cleansing agents according to the invention comprise at least one cationic nourishing polymer in an amount of 0.1 to 2 wt. % (based on the total weight of the hair cleansing agents) so as to enhance the nourishing properties of damaged hair. 
         [0058]    Suitable cationic nourishing polymers shall be understood to mean, for example:
       quaternized cellulose polymers, in particular Polyquaternium-10, as they are commercially available under the designations Celquat® and Polymer JR®;   hydrophobically modified cellulose derivatives, for example the cationic polymers sold under the trade name SoftCat®;   cationic alkyl polyglycosides;   cationized honey, for example the commercial product Honeyquat® 50;   cationic guar derivatives, such as in particular the products sold under the trade names Cosmedia®Guar N-Hance® and Jaguar®;   polymeric dimethyl diallyl ammonium salts and the copolymers thereof with esters and amides of acrylic acid and methacrylic acid, especially Polyquatemium-6 and Polyquaternium-7. The products available commercially under the designations Merquat®100 (poly(dimethyldiallylammonium chloride)) and Merquat®550 (dimethyldiallylammonium chloride/acrylamide copolymer) are examples of such cationic polymers;   copolymers of vinylpyrrolidone with quaternized derivatives of dialkyl aminoalkyl acrylate and methacrylate, such as diethyl sulfate-quatemized vinylpyrrolidone/dimethylaminoethyl methacrylate copolymers. Such compounds are commercially available under the designations Gafquat®734 and Gafquat®755;   vinylpyrrolidone/vinylimidazolium methochloride copolymers, as they are offered under the designations Luviquat® FC 370, FC 550, FC 905 and HM 552;   quatemized polyvinyl alcohol;   and the polymers known by the designations   Polyquaternium 2, Polyquaternium 17, Polyquatemium 18, Polyquaternium-24, Polyquaternium 27, Polyquatemium-32, Polyquatemium-37, Polyquatemium 74, and Polyquaternium 89.       
 
         [0070]    Particularly preferred cationic polymers are quaternized cellulose polymers, hydrophobically modified quaternized cellulose polymers, cationic guar derivatives and/or cationic polymers based on acrylic acid (derivatives), which particularly preferably are selected from the polymers known by the INCI names Guar Hydroxypropyltrimonium Chloride, Polyquaternium-6, Polyquatemium-7, Polyquatemium-10, Polyquaternium-37 and/or Polyquaternium-67. 
         [0071]    In a fourth preferred embodiment, hair cleansing agents according to the invention thus comprise at least one quaternized cellulose polymer, a hydrophobically modified quaternized cellulose polymer, a cationic guar derivative, a polymeric dimethyl diallyl ammonium salt and the copolymers thereof with esters and/or amides of acrylic acid and methacrylic acid, a copolymer of vinylpyrrolidone with quaternized derivatives of dialkylaminoalkyl acrylate and methacrylate and/or polyvinylpyrrolidone as the cationic nourishing polymer. 
         [0072]    Cationic polysaccharide polymers, and in particular quaternized cellulose polymers, have been found to be especially particularly preferred cationic nourishing polymers for the hair cleansing agents according to the invention. 
         [0073]    In a further preferred embodiment, hair cleansing agents according to the invention, based on the total weight thereof, thus comprise 0.01 to 2 wt. %, preferably 0.1 to 1.5 wt. %, and in particular 0.2 to 1 wt. % of at least one quaternized cellulose polymer, and in particular of a cationic polymer obtainable by reacting hydroxyethyl cellulose with trimethylammonium-substituted epoxides and known under the INCI name Polyquaternium-10. 
         [0074]    The above-described excellent balance between cleansing, mild and nourishing properties of the hair cleansing agents according to the invention was not achieved until calcium lactate (or alternatively a mixture of lactic acid and an inorganic calcium salt) was added to the mixture of anionic surfactants, non-ionic surfactants and cationic nourishing polymers on the one hand, and the pH value was set to a value in the range of 4.3 to 5.0 on the other hand. It is thus advantageous if no further acids than lactic acid and/or calcium lactate are used to set the pH value. 
         [0075]    To achieve the described nourishing effects, it is irrelevant whether calcium lactate or a mixture of lactic acid and an inorganic calcium salt is used in the hair cleansing agents. However, in the selection of the inorganic calcium salts, calcium chloride, calcium hydroxide, calcium sulfate and/or calcium oxide have proven to be particularly suitable. 
         [0076]    Likewise, it was found that calcium lactate or the mixture of lactic acid and an inorganic calcium salt must be used in a particular amount in the hair cleansing agents to achieve optimal nourishing effects. For example, particularly good nourishing effects (detanglability, combability and anti-frizz effect) were achieved with hair cleansing agents that, based on the total weight thereof, comprise
       i. 0.01 to 3 wt. %, preferably 0.02 to 2.5 wt. % and in particular 0.05 to 2 wt. % calcium lactate or   ii. 0.1 to 5 wt. %, preferably 0.5 to 4 wt. %, and in particular 1 to 3 wt. % lactic acid and 0.05 to 3 wt. %, preferably 0.1 to 2 wt. % and in particular 0.2 to 1 wt. % calcium hydroxide.       
 
         [0079]    In a fifth preferred embodiment, hair cleansing agents according to the invention thus comprise calcium chloride, calcium hydroxide, calcium sulfate and/or calcium oxide as the inorganic calcium salt d). 
         [0080]    In a sixth preferred embodiment, hair cleansing agents according to the invention, based on the total weight thereof, thus comprise
       i. 0.01 to 3 wt. %, preferably 0.02 to 2.5 wt. % and in particular 0.05 to 2 wt. % calcium lactate or   ii. 0 1 to 5 wt. %, preferably 0.5 to 4 wt. %, and in particular 1 to 3 wt. % lactic acid and 0.05 to 3 wt. %, preferably 0.1 to 2 wt. % and in particular 0.2 to 1 wt. % calcium hydroxide.       
 
         [0083]    An especially particularly preferred embodiment of the present invention is characterized in that the hair cleansing agents, based on the total weight thereof, comprise
       a) 6 to 12 wt. % of at least one anionic alkyl ether sulfate salt of formula R—(OCH 2 —CH 2 ) x —OSO 3- X+, in which R denotes a straight-chain or branched alkyl group having 8 to 18, and in particular 10 to 16, carbon atoms, x denotes 1 to 6, and in particular 2 to 4 ethylene oxide units, and X +  denotes a sodium, magnesium and/or triethanolamine cation,   b) 0.1 to 5 wt. % of at least one fatty acid alkanolamide of formula       
 
         [0000]    
       
                 
         
             
             
         
       
       
         
           
             in which R preferably denotes a linear or branched, saturated or unsaturated alkyl or alkenyl group having 8 to 24 carbon atoms, and the groups R′ denote hydrogen or the group —(CH 2 ) n OH, in which n denotes the number 2 or 3, with the proviso that at least one of the groups R′ denotes the aforementioned group —(CH 2 ) n OH; 
             c) 0.01 to 2 wt. % of at least one quaternized cellulose polymer, and 
             d) (i) 0.01 to 3 wt. % calcium lactate or
           (ii) 0.1 to 5 wt. % lactic acid and 0.05 to 3 wt. % calcium hydroxide, and have a pH value in the range of 4.3 to 5.0, preferably of 4.4 to 5.0, preferably of 4.5 to 4.9, and in particular of 4.5 to 4.8.   
         
           
         
       
     
         [0090]    Within this embodiment, in particular hair cleansing agents are preferred that, based on the total weight thereof, comprise
       a) 1 to 11 wt. % of at least one sodium, magnesium and/or triethanolamine salt of a linear or branched lauryl, tridecyl and/or myristyl sulfate having a degree of ethoxylation of 2 to 4,   b) 0.2 to 3 wt. % of at least one fatty acid alkanolamide known under the INCI name Cocamide MEA,   c) 0.1 to 1.5 wt. % of at least one quaternized cellulose polymer known under the INCI name Polyquaternium-10, and   d) (i) 0.02 to 2.5 wt. % calcium lactate or
           (ii) 0.5 to 4 wt. % lactic acid and 0.1 to 2 wt. % calcium hydroxide, and have a pH value in the range of 4.5 to 4.9, and in particular of 4.5 to 4.8.   
               
 
         [0096]    The visual and haptic properties of the hair cleansing agents according to the invention can be even further increased when other hair nourishing agents are added to these. Possible other hair nourishing agents that are suitable are cosmetically suitable oil, fat and/or wax components, vitamins and/or protein hydrolysates. 
         [0097]    Cosmetically suitable oil, wax and/or fat components can preferably be selected from mineral, natural and synthetic oil components and/or fats.

         [0186]    2) Evaluation of Shampoos According to the Invention 
         [0187]    In a side-by-side experiment, one half of damaged, long hair was washed in the customary manner with a shampoo according to the invention (FDH14CB0003/13), which corresponds to above Example 1. The other half was washed in the customary manner with the same amount of a conventional nourishing shampoo (FDH14CB0003/12). The composition of the conventional nourishing shampoo likewise corresponded to above Example 1, except that citric acid (instead of lactic acid) was used to acidify the shampoo and the shampoo did not include calcium salt. Both shampoos had a pH value of 4.75. After the shampoos were rinsed off with water, the properties of the wet and dry hair listed below were compared to each other and rated simultaneously by 10 experts on a scale from 0 to 2.5 (differences&gt;0.5 are significant; the formulation showing the reading in the diagram on its side was rated better by the experts in terms of the respective property). 
         [0188]    This is illustrated by  FIG. 1 . 
         [0189]    It is clearly apparent from the diagram that half the hair, which was washed with the shampoo according to the invention, has noticeably better nourishing properties when wet and when dry.
