Definitions

• This invention relates to detergent compositions containing quaternary ammonium salts.
• Cationic surface active agents have been employed as constituents of hair-conditioning and fabric treating compositions. When these agents are combined with anionic surface active agents in proportions to give homogeneous solutions, the cationic agents generally do not become adsorbed on the hair or fabric to an appreciable extent and the compositions do not foam well, particularly in hard water.
• the cationic agents By combining the cationic agents with selected amphoteric or non-ionic surface active agents, compositions which impart anti-static properties to hair can be produced, but such compositions have relatively poor foaming properties or have a noncosmetic feel during shampooing.
• Another object of this invention is the provision of a foaming detergent composition which is unaffected by hard water.
• Still another object of this invention is the provision of a detergent containing soap and a cationic surface active agent which will foam in hard and soft water.
• a detergent composition particularly suitable for use as a hair-conditioning shampoo, containing a cationic surface active agent, an anionic surface active agent and a surface active amine oxide.
• the cationic surface active agents employed in this invention are quaternary ammonium salts having a long chain hydrophobic radical. Especially effective are such compounds as oleyl or stearyl dimethyl benzyl ammonium salts.
• the oleyl or stearyl radicals may be replaced by other long chain alkyl radicals such as undecylenyl, lauryl, myristyl or cetyl, or by long chain radicals having other groups (e.g. aryloxyethyl groups as in diisobutyl phenoxyethoxyethyl dimethyl benzyl ammonium chloride); the
• benzyl radical may be replaced by a substituted benzyl radical such as 3,4-dichlorobenzyl, 3,4-dimethylbenzyl, ethylbenzyl, etc., or by an alkyl radical such as methyl, ethyl, lauryl or stearyl (e.g. in di-long chain alkyl dimethyl ammonium chlorides, cetyl trimethyl ammonium bromide, oleyl dimethyl ethyl ammonium bromide, myristyl dimethyl 3,4-dichlorobenzyl ammonium chloride).
• the quaternary ammonium salt may have the nitrogen in a ring, e.g.
• an alkyl isoquinolinium salt e.g. lauryl isoquinolinium bromide
• an imidazolinium compound such as a l-methyl-l-alkylamidoethyl-Z alkylimidazolinium salt in which the alkyl groups have an average chain length of 17 carbon atoms.
• a quaternary nitrogen atom directly linked to a carbon atom of a hydrophobic radical of at least ten carbon atoms (such as a long chain alkyl radical or an alkylaryl radical, in which there are 10-20 carbon atoms, for example), three valences of the nitrogen atom being also directly linked to other carbon atoms which may be in separate radicals (such as alkyl, particularly lower alkyl, or aralkyl radicals) or in a cyclic structure including the quaternary nitrogen atom (as in a morpholine, pyridine, quinoline or imidazoline ring).
• a hydrophobic radical of at least ten carbon atoms such as a long chain alkyl radical or an alkylaryl radical, in which there are 10-20 carbon atoms, for example
• three valences of the nitrogen atom being also directly linked to other carbon atoms which may be in separate radicals (such as alkyl, particularly lower alkyl, or aralkyl
• hydrophobic radical may be a simple hydrocarbon or hydrocarbon ether radical, it may also contain substituents such as halogen, and may even contain intermediate linkages, such as the amide and ester linkages of the higher alkanoyl colamino formylmethyl radical .RCOOCH CH NHCOCH although, as will be seen from the following examples, the presence of such amide or ester linkages is not at all essential in the practice of this invention.
• the anion of the quaternary ammonium salt is most usually a chloride or methosulfate (OSO- OCH ion, but other ions may be used as is Well known in the art, e.g. bromide, phosphate, dialkyl phosphate, or acetate lOIlS.
• the anionic surface active agent used is preferably a soap.
• the after-effects of any traces of material left on the hair are generally better, in soft water, when soaps are used than when other anionic surface active agents, containing sulfate or sulfonate groups, are employed in place of the soap.
• the use of hard water usually changes this, causing the deposition of a dull soap film; however, unlike the usual soap-containing compositions the preferred compositions of this invention foam well in hard water, as will be seen from the examples given below, even when the free fatty acid of the soap is present
• Preferred soaps are those of triethanolarnine, potassium, sodium, diethanolamine, morpholine and diglycolamine.
• the acid portion of the soap is advantageously that of a fatty acid such as lauric, myristic, stearic, oleic, elaidic, isostearic, palmitic, undecylenic, tridecylenic, pentadecylenic or other saturated or unsaturated fatty acid of 11 to 18 carbon atoms.
• Soaps of dicarboxylic acids may also be used such as the soaps of dimerized linoleic acid. Soaps of such other higher molecular weight acids such as rosin or tall oil acids, e.g. abietic acid, may also be employed.
• Other suitable anionic surface active agents are the carboxyl-containing amides of fatty acids with amino acids (e.g.
• lauric acid amide of such amino acids as sarcosine, beta amino propionic acid, polypeptides from hydrolysis of proteins, isethionic acid or N- methyl tauric acid) and soluble salts of such carboxylcontaining amides.
• anionic surface active agents which may be used are sulfates of fatty alcohols such as sodium lauryl sulfate, Turkey Red Oil or other sulfated oils, or sulfates of monoor di-glycerides of fatty acids (e.g. stearic monoglyceride monosulfate), alkyl poly(ethenoxy)ether sulfates such as the sulfates of the condensation products of ethylene oxide and lauryl alcohol (usually having 1 to 6 ethenoxy groups per molecule); aliphatic sulfonates such as alkane sulfonates (e.g.
• the anionic surface active agent may be an alkyl benzene sulfonate such as sodium dodecyl benzene sulfonate.
• the anionic surface active agents have hydrocarbon radicals of at least 10 carbon atoms, preferably long chain hydrophobic aliphatic radicals of about 11 to 18 carbon atoms.
• the cations of these surface active agents are advantageously such as to impart watersolubility to the acidic portion of the molecule or to maintainits water-solubility, e.g.'triethanolammonium or other alkanolamrnonium, potassium, sodium, magnesium (when the surface active agent forms a water-soluble magnesium salt), diethanolammonium, or (particularly when the blend is not acidic) ammonium.
• a preferred amine oxide is lauryl dimethyl amine oxide.
• lauryl radical other long chain alkyl radicals, advantageously of about 10 to 18 carbon atoms, such as decyl, tetradecyl, cetyl, oleyl, hexadecyl or stearyl, may be employed.
• methyl radicals there may be used an ethyl, propyl, hydroxyethyl, hydroxyethoxyethyl or hydroxy polyethoxyethyl radical.
• the long chain hydrophobic radical attached to the nitrogen of the amine oxide need not be only a hydrocarbon radical, It may, for example, contain other groups, such as carbonamide groups, such as in amine oxides of the formula in which RC is a long chain alkanoyl radical, n is a small whole number, and R and R are lower aliphatic groups; a specific example being the compound in which RC0 is the acyl radical of coco fatty acids, n is 2 and R and R are methyl.
• the proportions of amine oxide and anionic detergent are advantageously each in the range of about -25% of the total aqueous detergent composition, and the weight ratio of these two components is advantageously in the range of about 1:4 to 4: 1.
• the proportions of the cationic agent are advantageously less than desirably in the range of about %.-5%' of the total aqueous detergent composition, preferably about 1 to 2%; the ratio of quaternary ammonium compound to anionic detergent may be, for example, in the range of about 2:3 to 1:10; for hair shampoos this ratio, for best results, is in the range of about 1: 4 to -1 10.
• Best results in terms of antistatic effects on the hair are attained when the pH of the composition is below about 8 /2, preferably below about 8, eg in the range of about 5 to 7 /2.
• Homogeneity of the composition at such lower pHs is promoted by the use of relatively large amounts of the amine oxide and/ or cationic agent. Homogeneity is also promoted by the incorporation of water-soluble alcohols such as ethanol, propylene glycol, glycerol, sorbitol, hexylene-glycol, polyglycerol, dipropylene glycol or other polyols; these inert solvents are advantageously employed in concentrations up to 10%, e.g. in the range of about 3 to 10%.
• anionic-cationic-amine oxide compositions of this invention may be employed as shampoos, or as detergents for other fibrous material, particularly for fabrics of wool, silk or other protein fibers.
• Compositions of these components may also be used as foaming after-rinses, or conditioners for hair or fabrics. They may be used as anti-dandruff rinses or scrub soaps.
• the homogeneous compositions On dilution with water the homogeneous compositions become cloudy. It is believed that this may be due to the fact that there is present in the compositions a complex of the amine oxide and quaternary ammonium salt, with or without the anionic surface active agent, which complex is soluble above its critical micelle concentration but insoluble in dilute solution.
• the proportions of water and inert solvent in the homogeneous compositions are advantageously well within the range of 50- preferably about 60-80%.
• EXAMPLE 1 6% of triethanolamine oleate soap, 10% of lauryl dimethyl amine oxide and 2% of a cationic dispersing agent, consisting of oleyl dimethyl benzyl ammonium chloride, were dispersed in water. The mixture, which had a pH of 8.0, was clear. The pH was then reduced to 6.9 by the addition of a 50% aqueous solution of citric acid; the composition remained clear. Dispersions of the resulting composition in either hard or soft water gave large volumes of foam.

• composition When the composition was used for shampooing hair, it was found that a considerable proportion of the cationic dispersing agent was absorbed by the hair and that after shampooing and drying the hair was soft and smooth and had little or no tendency to acquire a static electrical charge and to fly apart.
• EXAMPLE 2 10% of a soap, consisting of the triethanolamine salt of oleic acid, 9% of lauryl dimethyl amine oxide, and 1.6% of a cationic dispersing agent, consisting of oleyl dimethyl benzyl ammonium chloride, were dispersed in water. The resulting mixture, which had a pH of 8.2, was clear. The composition foamed well when it was dispersed in either hard or soft water; in contrast, when the amine oxide was omitted from the composition, the foam volume in soft water was much lower than when it was present, and the foam volume in hard water was considerably lower than that in soft water. When the composition was used for shampooing hair, it was found that, after shampooing and drying, the hair was soft and smooth and had little or no tendency to acquire a static electrical charge and to fly apart.

On dilution with 43 parts of water and addition of sufficient triethanolamine to raise the pH of the mixture to 7.4 (thus forming the triethanolamine soap of the myristic acid) there was produced a clear, homogeneous product with good shampooing properties.
• EXAMPLE 7 5 parts of triethanolamine myristate, 5 parts of lauryl poly(ethenoxy) ether sulfate having 3-4 ethenoxy groups per lauryl group, 9 parts of lauryl'dimethyl amine oxide and 1.5 parts of oleyl dimethyl benzyl ammonium chloride were mixed with 78 parts of water. The resulting clear mixture had a pH of 7.7.
• EXAMPLE 8 10 parts of triethanolamine dodecyl benzene sulfonic and 10 parts of lauryl dimethyl amine oxide were mixed with 67 parts of water, 3 parts of oleyl dimethyl benzyl ammonium chloride, and 10 parts of-ethanol (Specially Denatured, standard formula 40). The resulting mixture was opaque; on addition of 3 additional parts of oleyl dimethyl benzyl ammonium chloride the mixture cleared.
• EXAMPLE 9 (a) 10 parts of triethanolamine oleate, 9 parts of lauryldimethyl amine oxide and 1.5 parts of di-isobutylphenoxy-ethoxy-ethyl dimethyl benzyl ammonium chloride were mixed with 79 parts of water. The resulting solution, having a pH of 8.4, was clear.
• the simple fatty acids and their soaps may be replaced with more complex carboxylic acids or their corresponding soaps, particularly with the acids or soaps of the amides of amino acids (e.g. amides of fatty acids such as sarcosine, beta-aminopropionic acid or polypeptides obtained by hydrolysis of proteins, such as Maypons made with peptides from hydrolysis of collagen, the degree of polymeriaztion of the peptide being, for example, about 2-5).
• Example 10 illustrates one such formulation.
• EXAMPLE 10 An effective hair shampoo was produced by mixing in water 10% of N-lauroyl sarcosine (free acid form), 6% of lauryl dimethyl amine oxide, 2% oleyl dimethyl benzyl ammonium chloride and sutficient triethanolamine to bring the pH to 7.0.
