CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a continuation-in-part of Ser. No. 054,342, filed May 26, 1987, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a detergent composition. More specifically, it relates to a detergent composition suitable for use as, for example, a hair or body shampoo or a garment or dish detergent containing (i) a quaternary ammonium cationic surfactant, (ii) a carboxylate anionic surfactant, and (iii) an amphoteric surfactant and/or (iv) a nonionic surfactant. 
     2. Description of the Related Art 
     Conventionally, anionic surfactants and amphoteric surfactants are generally incorporated, as a main foaming detergent, into shampoos. But, when only these surfactants are incorporated into shampoos, although a sufficient detergent power for washing the hair can be obtained, the applicability of the shampoos is not satisfactory, especially when a so-called &#34;squeak&#34; phenomenon in the hair is remarkable. Various attempts have been made to solve this &#34;squeak&#34; problem by formulating, for example, cationic polymers or cationic surfactants, whereby conditioning effects affording, for example, a smoothness to the hair, are desired. The use of cationic polymers, however, causes an accumulation thereof on the hair. On the other hand, the amount of cationic surfactants used in shampoos is limited, since cationic surfactants irritate the skin. Accordingly, shampoos having satisfactory conditioning effects have not been obtained, although products having high conditioning effects are needed. 
     SUMMARY OF THE INVENTION 
     Accordingly, the objects of the present invention are to eliminate the above-mentioned disadvantages of the prior art and to provide a detergent composition having an excellent conditioning effect and low skin irritation. 
     Other objects and advantages of the present invention will be apparent from the following description. 
     In accordance with the present invention, there is provided a detergent composition comprising, in an aqueous medium, (i) at least one quaternary ammonium cationic surfactant selected from the group consisting of (a) monoalkyl quaternary ammonium salt cationic surfactants having the formula (I): ##STR4## wherein R 1  represents an alkyl or alkenyl having 12 to 22 carbon atoms, R 2 , R 3 , and R 4  independently represent methyl or ethyl, and X 1  represents a halogen atom or a methylsulfate residue, (b) ethylene oxide addition quaternary ammonium salt cationic surfactants having the formula (II): ##STR5## wherein R 5  represents an alkyl having 16 to 22 carbon atoms, R 6  represents methyl, ethyl, or an alkyl having 16 to 22 carbon atoms, X 2  represents a halogen atom or a methylsulfate or ethylsulfate residue, m and n are independently 0 or an integer of at least 1, provided that the sum of n and m is 1 to 30, and (c) imidazoline quaternary ammonium salt cationic surfactants having the formula (III): ##STR6## wherein R 7  and R 8  independently represent an alkyl or alkenyl having 12 to 22 carbon atoms, and X 3  represents an halogen atom or a methyl sulfate or ethylsulfate residue; 
     (ii) at least one carboxylate anionic surfactant, and 
     (iii) at least one amphoteric surfactant and/or (iv) at least one nonionic surfactant, the mole ratio of the components (i)/(ii) being within the range from 4/6 to 8/2. 
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present inventors have made an intensive study of a detergent composition such as a shampoo having a conditioning effect and low skin irritation and, as a result, found that the use of the specified quaternary ammonium cationic surfactants and carboxylate anionic surfactants at a specified ratio and in combination with amphoteric surfactants, and/or nonionic surfactants can provide a detergent composition satisfying the above-mentioned objects. 
     When anionic surfactants and cationic surfactants are present together in an aqueous solution, complexes are generally formed in the crystalline phase and the complex is precipitated to make the solution turbid, or to cause separation of the complex. Namely, when quaternary ammonium salt type cationic surfactants are mixed in an aqueous solution with anionic surfactants such as sulfonate type surfactants (e.g., higher alkyl sulfonates), sulfuric acid ester salt type surfactants (e.g., salts of higher alcohol sulfates), or phosphoric acid ester salt type surfactants (e.g., salts of polyoxyethylene alkylether phosphonic acid ester), complexes are formed in the crystalline phases at any mole ratio and the resultant complexes are precipitated, and thus the aqueous solution becomes turbid or the complexes are separated from the aqueous solution. But, when monoalkyl quaternary ammonium salt cationic surfactants are combined with carboxylic acid salt anionic surfactants at specific mole ratios in aqueous solutions, the complexes are not formed in the crystalline phases but in the solution, and the resultant complexes are transparent and have excellent conditioning effects and low skin irritation. Nevertheless, although these complexes have the above-mentioned advantages, the foaming power and detergency thereof are not as high as in a conventional shampoo. According to the present invention, the foaming power and the detergency can be advantageously improved, without impairing the desired conditioning effect and the desired skin safety, by incorporating amphoteric surfactants and/or nonionic surfactants into the above-mentioned composition. 
     The cationic surfactants usable in the present invention are one or more of quaternary ammonium salts having the above-mentioned general formulae (I), (II), and (III). When dialkyl type quaternary ammonium cationic surfactants or other cationic surfactants are used, instead of the quaternary ammonium salts, (I), (II), and (III), crystallines are precipitated and the desired composition cannot be obtained. 
     Examples of the monoalkyl quaternary ammonium salt cationic surfactants (I) are stearyltrimethylammonium chloride, myristylmethylammonium chloride, and palmityldimethylethylammoniumethyl sulfate. 
     Examples of the ethylene oxide addition quaternary ammonium salt cationic surfactants (II) are dipolyoxyethylene (2 mol addition) stearylethylammonium bromide and dipolyoxyethylene (4 mol addition) behenylmethylammonium chloride. 
     In the present invention, any surfactant having one or more --COO--groups may be used as the carboxylate anionic surfactant. Examples of the carboxylate anionic surfactant are as follows: 
     (A) Fatty acid soap anionic surfactants having the formula: 
     
         R.sub.9 COOM.sub.1 
    
     wherein R 9  represents an alkyl or alkenyl group having 8 to 18 carbon atoms, M 1  represents one or more of alkali metals, organic amines, and basic amino acids (e.g., sodium laurate, potassium myristate, sodium oleate, sodium stearate, behenic acid triethanolamine salt); and 
     (B) Ether carboxylate anionic surfactants having the formula: 
     
         R.sub.10 (OCH.sub.2 CH.sub.2).sub.x OCH.sub.2 COOM.sub.2 
    
     wherein R 10  represents an alkyl or alkenyl group having 8 to 22 carbon atoms, x is zero or an integer of 1 to 16, and M 2  represents one or more of alkali metals, organic amines, and basic amino acids (e.g., sodium polyoxyethylene (3 mol addition) lauryl ether acetate, sodium polyoxyethylene (6 mol addition) myristyl ether acetate). 
     As the carboxylate anionic surfactant, a condensation product of a higher fatty acid and an amino acid (e.g., sarcosine, β-alanine, methyl-β-alanine, glutamic acid, glycine, valine, or leucine) may be used. Examples of such carboxylate anionic surfactant are as follows: 
     (C) N-acylsarcosinate anionic surfactants having the formula: ##STR7## wherein R 11  represents an alkyl or alkenyl group having 8 to 18 carbon atoms and M 3  represents one or more of alkali metals, organic amines and basic amino acids (e.g., potassium N-lauroylsarcosinate, N-stearoylsarcosinate triethanolamine salt); 
     (D) N-acrylglutamates represented by ##STR8## wherein R 12  represents an alkyl or alkenyl group having 8 to 18 carbon atoms and M 4  independently represents one or more of alkali metals, organic amines, and basic amino acids; 
     (E) N-acyl-N-methyl-β-alanine salt anionic surfactant represented by ##STR9## wherein R 13  represents an alkyl or alkenyl group having 8 to 18 carbon atoms and M 5  represents one or more of alkali metals, organic amines, and basic amino acids; and 
     (F) N-acyl alanine salt anionic surfactant represented by 
     
         R.sub.14 CONHCH.sub.2 CH.sub.2 COOM.sub.6 
    
     wherein R 14  represents an alkyl or alkenyl group having 8 to 18 carbon atoms and M 6  represents one or more of alkali metals, organic amines, and basic amino acids. 
     Further, as the carboxylate anionic surfactant, there may be used dicarboxylate surfactant (G) having the formula: ##STR10## wherein n and s are independently an integer of 3 to 9, period that the sum of n and s is 12, one Z represents a hydrogen atom, the other Z represents --COOM 8 , and M 7  and M 8  independently represent one or more alkali metals (e.g., potassium), ammonium, organic amines (e.g., alkanolamine) and a basic amino acids. 
     The above-mentioned anionic surfactants may be used alone or in any mixture thereof. The present detergent composition must contain the component (i), i.e., the quaternary ammonium salt cationic surfactants, and the component (ii), i.e., carboxylate anionic surfactants, at a mole ratio of the components (i)/(ii) of 4/6 to 8/2, preferably 5/5 to 7/3. When the mole ratio is less than 4/6, the conditioning effect of the resultant detergent composition is reduced. Contrary to this, when the mole ratio is more than 8/2, the skin irritation caused by the resultant detergent composition is unpreferably strong. 
     Although there are no critical limitations to the total amount of the components (i) and (ii) in the detergent composition, the total amount of the components (i) and (ii) is preferably 0.5% to 20% by weight, more preferably 1% to 15% by weight, based on the total amount of the present detergent composition. When the total amount of the components (i) and (ii) is less than 0.5% by weight, the conditioning effect tends to be decreased because the amount of the surfactants is insufficient. Contrary to this, when the total amount of the components (i) and (ii) is more than 20% by weight, the skin irritation tends to become strong. 
     The amphoteric surfactants usable in the present invention are those which can be used in conventional shampoos. Typical examples of such amphoteric surfactants are imidazoline amphoteric surfactants such as sodium 2-undecyl-N,N,N-(hydroxyethylcarboxymethyl)-2-imidazoline, 2-cocoyl-2-imidazoliniumhydroxide-1-carboxyethyloxy-2-sodium; betaine amphoteric surfactants such as 2-heptadecyl-N-carboxymethyl-N-hydroxyethyl imidazolinium betaine, betaine lauryl dimethylamino acetate; coconut fatty acid amide dimethylamino acetic acid betaine, laurylsulfo betaine, amine oxides. 
     These amphoteric surfactants may be used alone or in any mixture thereof. Although there are no critical limitations to the amount of the amphoteric surfactant in the composition, this amount is preferably 0.1% to 20% by weight, especially 5% to 15% by weight, based on the total amount of the composition, in the present detergent composition. 
     The nonionic surfactants usable in the present invention are those having an HLB of 4 to 20 and alkyl glycosides having the formula (IV): ##STR11## wherein p is an integer of 1 to 15 and q is an integer of 7 to 19. 
     Examples of the nonionic surfactants having an HLB of 4 to 20 are POE (i.e., polyoxyethylene) sorbitane monooleate, POE sorbitane monostearate, POE-sorbitane monooleyl ether, POE-POP alkyl ethers such as POE-POP hydrogenated lanolin, POE-POP glycerine ether, POE lauryl ether; tetraPOE-tetraPOP ethylenediamine condensates such as Tetronic; POE castor oil, POE hardened castor oil, POE castor oil or hardened castor oil derivatives such as POE hardened castor oil monoisostearate, POE hardened castor oil triisostearate, POE hardened castor oil monoglutamate monoisostearate diester, POE hardened castor oil maleate; POE beeswax-lanolin derivatives such as POE sorbitol beeswax; alkanolamides such as coconut fatty acid diethanolamide, lauric monoethanolamide, fatty acid isopropanolamide; POE propylene glycol fatty acid ester, POE alkyl amine, POE fatty acid amide, sucrose fatty acid ester, POE nonylphenyl formaldehyde condensate, alkylethoxydimethylamine oxide, trioleyl phosphoric acid. 
     Examples of the alkylglycosides (IV) are those having a straight alkyl group with 8 to 20 carbon atoms, in particular, an alkylglucoside having a straight alkyl group with 10 to 16 carbon atoms has an excellent foaming richness, and can be used either individually or as a mixture. The sugar moiety is glucose or an oligosaccharide having glucose as the unit. The number of glucose units may be 1 to 15, preferably 1 to 5, and the bonding between glucoses may be either α or β, or a mixture thereof. 
     The amount of the nonionic surfactants having an HLB of 4 to 20 or the alkylglucoside to be used in the present invention is preferably 5 to 70% by weight of the total amount of the composition, more preferably 8 to 60% by weight. With an amount less than 5% by weight, the foam richness is undesirably reduced. 
     The detergent compositions according to the present invention may contain, in addition to the above-mentioned essential constituents, any conventional ingredients and additives generally used, as optional components, in detergent compositions, as long as the desired properties of the present invention are not adversely affected. 
     Examples of such optional components are oils such as higher alcohols (e.g., cetyl alcohol, stearyl alcohol), silicone oils (e.g., dimethyl polysiloxanes having a polymerization degree of 4 to 6000, methyl phenyl siloxane), liquid paraffins (e.g., hydrocarbon oils such as squalane, cetyl isooctanoate, distearyl acid ethylene glycol), and ester oils; water-soluble polymers such as methyl cellulose, hydroxyethyl cellulose; cationic polymers such as cationic modified cellulose ether derivatives (e.g., Polymer JR commercially available from Union Carbide Corporation); and polydimethylallyl ammonium chloride (Mercoat 100 commercially available from Merk Co.); copolymers of dimethyldiallylallylammonium chloride and acrylamide (Mercoat 550 commercially available from Merk Co.); the condensate products of polyglycol and polyamine (e.g., polycoat H commercially available from Henkel Corporation); organic acids such as citric acid and lactic acids; hydrogenase such as protease; inorganic salts such as sodium chloride and potassium chloride; anti-bacteria; inorganic builders; fluorescent agents; perfumes or flavors; coloring agents; preservatives; chelating agents; and UV absorbers; and natural extracts of animals and vegetables and the derivatives thereof.

     o: Good 
     Δ: Fair 
     x: Poor 
     2. Skin irritation 
     It is known in the art that skin irritation can be evaluated by a degree of the denaturing activity for proteins (i.e., &#34;protein denaturation&#34;) of surfactants or the compositions thereof (see JP-B-59-42038). The skin irritation was evaluated by a protein denaturation in this manner in the following Examples. 
     The protein denaturation was determined as follows. 
     A sample composition was added to an egg white albumin solution buffered to a pH of 7 so that the sample concentration was 1%. The denaturing percentage of the egg white albumin was determined by using an absorption peak at 220 nm as follows. ##EQU1## wherein 
     H 0  : height of absorption peak of egg white albumin at 220 nm 
     H S  : height of absorption peak at 220 nm when the sample was added to the egg white albumin buffered solution. 
     The evaluation was carried out by the following four-stage standards. 
      ○o  : Very slight skin irritation (i.e., denaturation is less than 30%) 
     o: Little skin irritation (i.e., denaturation is not less than 30% but less than 60%) 
     Δ: Middling skin irritation (i.e., denaturation is not less than 60% but less than 80%) 
     x: Strong skin irritation (i.e., denaturation is 80% or more)
