Title: Liquid detergent fabric conditioning compositions

Description:
The present invention is concerned with liquid detergent fabric conditioning compositions containing a novel optical brightening agent, which compositions are added during the wash cycle of the laundering process. 
     It is known in the art to produce liquid and particulate laundry detergents and to add these during the wash cycle. It is also known in the art to add liquid fabric softener and anti-static compositions during the wash or rinse cycle of the laundering process. In recent years, it has been found convenient to separate the fabric softening and anti-static function from the detergent function by preparing a separate fabric softener and anti-static material which was added to the fabrics to be rendered soft and static-free during the drying cycle, rather than during the course of the wash or rinse cycle. It is also known in the art to prepare liquid detergents which also impart fabric softening and anti-static properties to fabrics during the course of the wash cycle of the laundering process. 
     More particularly, the following patents describe various detergent compositions for use during the wash cycle of the laundering process. U.S. Pat. No. 4,298,480 describes a detergent composition which provides softness, detergency, anti-static and anti-soil redeposition properties to fabrics and which comprises a water-soluble, non-soap, organic surfactant at least about 90% of which is of the anionic type, a water-soluble neutral to alkaline builder salt, a water-soluble or dispersible fatty acid soap in discrete particle form, a cationic softener selected from aliphatic di C 1  -C 4  alkyl,di(higher) C 14  -C 24  alkyl quaternary ammonium compounds, heterocyclic compounds and mixtures thereof, the weight ratio of soap to softener being from about 2:3 to 3:2 and wherein the percent concentration of anionic surfactant is at least about 1.5×+5, wherein x is the percent concentration of softener, wherein the soap is substantially homogeneously dispersed in the composition preferably as discrete particles. U.S. Pat.

No. 3,920,564 describes the incorporation of cationic and amine fabric softeners into anionic and nonionic detergent compositions where the builder is a water-soluble salt of an amino-polycarboxylate or a water-soluble salt of citric acid rather than the usual sodium or potassium tripolyphosphate. The substitution of an aminopolycarboxylate salt or a citric acid salt for tripolyphosphate as a builder is stated to increase the functionality of cationic and amine-type fabric softeners in a detergent fabric softener. 
     U.S. Pat. No. 3,844,952 describes laundry detergent compositions comprising a water-soluble organic detergent compound an α,ω-disubstituted derivative of a non-cyclic, hygroscopic polyol, and in a preferred embodiment a polyalkyleneimine anti-static agent.

Canadian Pat. No. 1,031,907 describes non-phosphate detergents consisting essentially of about 10 to about 40% of a synthetic organic detergent selected from C 16  -C 22  alkyl di-(C 1  -C 3 )alkylamineoxide, water-soluble nonionic surface active compounds derived from condensation of a C 8  -C 50  hydrophobic compound with from 5 to 200 moles of ethylene oxide or a mixture thereof and about 3 to 15% of a mixture of a quaternary ammonium fabric softener which is a di-long chain or di-short chain quaternary ammonium compound or a mono- or di-long chain alkylimidazolinium compound and a polyethoxylated quaternary ammonium compound containing from 10 to 60 moles of ethylene oxide, the elements in the composition being present in specified ratios. 
     Canadian Pat. No. 1,005,204 is a typical example of a dryer-added fabric softener which comprises a substrate having a fabric conditioning agent thereon which is co-mingled with the clothes to be conditioned in the laundry dryer. 
     Canadian Pat. No. 818,419 describes fabric softener detergent compositions comprising an electro-neutral complex of a cationic textile softening agent and an anionic surfactant and a nonionic -cationic dispersing mixture which is capable of dispersing the composition into an active dispersion. The electro-neutral complex is stated to make up a critical portion of the composition and is formed by combining a cationic textile softening agent with an anionic surfactant in the presence of a nonionic -cationic dispersing agent in amounts which will form a substantially unionized cationic-anionic complex. 
     Canadian Pat. No. 783,532 describes detergent softener compositions which comprise a nonionic detergent and a cationic softener and a nonionic soil suspending agent, the detergent and the fabric softener being present in a ratio by weight of from about 0.5:1 to 2.5:1. The nonionic detergent is a condensation product of polyethyleneoxide in which the polyethyleneoxide chain acts as the hydrophilic group and the hydrophobic group is derived from materials such as fatty acids, alcohols, mercaptans, amines, amides, substituted phenols, fatty alcohols and glucosides. 
     Canadian Pat. No. 755,039 describes a fabric softening composition which can be used during the wash cycle of the laundering process together with a laundry detergent. The fabric softeners described are cation-active organic compounds which are capable of forming solid complexes that are adducts with urea. 
     Canadian Pat. No. 743,513 describes compositions comprising a cationic fabric softening agent which is a water-soluble 1-lower alkyl, 1-long chain alkylamidoethyl-2-long chain alkyl imidazolinium salt and a germicidal agent which is a water-soluble N-alkyl, N,N-di-lower alkyl N-arylmethyl ammonium salt having a long chain alkyl group. As with the preceeding Canadian patent, this composition is intended to be added during the laundering process and does not include a detergent within the composition. 
     Canadian Pat. No. 730,150 describes the chemical treatment of fibrous material such as textiles and paper for the purpose of providing softness to those materials. This reference discloses 1,2-amide imidazoline salts which are stated to have good re-wetting and good anti-static properties for textiles and paper. Canadian Pat. No. 713,521 describes solid laundry compositions comprising a mixture of a cationic fabric softener and a sugar. The sugar is used as a carrier, stabilizer and solubilizer for the fabric softener. Canadian Pat. No. 702,646 describes a fluid colloidal preparation which comprises at least one cationic fabric softener which is preferentially absorbed by cloth, at least one organomercurial germicide, and a minor proportion of thin boiling cornstarch. The cationic softener is stated to exert a potentiating effect upon the germicidal activity of the organomercurial compound as well as aiding in more uniform absorption of the germicide into the fabrics being treated with the composition. 
     By contrast to the prior art, the present invention provides a liquid detergent fabric conditioning composition which contains a novel and effective optical brightening agent. The composition according to the present invention contains both a cationic fabric conditioning agent and a non-ionic surfactant. Most optical brightening agents do not perform well in cationic systems, such as those of the present invention. While most optical brighteners are compatible with anionic surfactants, they lose their effectiveness when they are combined with cationic and non-ionic surfactants. It is therefore most surprising that the optical brightening agent used in the composition of the present invention is effective, not only because it is utilized in a fabric conditioning system containing a cationic fabric conditioning agent and a non-ionic surfactant, but because the agent has not been heretofore known as possessing or exhibiting any optical brightening characteristics. 
     More particularly, the present invention provides a liquid detergent fabric conditioning composition which comprises an effective amount of a cationic fabric conditioning agent, an effective amount of a non-ionic surfactant having detergent properties compatible with said cationic fabric conditioning agent, an optical brightening amount of a C 21  dicarboxylic acid, salt thereof or mixture thereof and an aqueous solvent system. The C 21  dicarboxylic acid and salts thereof, which are useful as optical brightening agents in the composition of the present invention, are described in U.S. Pat. No. 3,966,628 as surfactants. The C 21  dicarboxylic acid is represented by the structural formula: ##STR1## wherein x and y are integers from 3 to 9, x and y together=12, one Z is hydrogen and the other Z is a carboxylic acid group (COOH). Isomers wherein x is 5 and y is 7 frequently form a preponderance of the acid composition, although there may be minor amounts of the C 21  dicarboxylic acid where the cyclohexene ring varies in position along the carbon chain. 
     As the important aspect of the optical brightening agent used in the composition of the present application is the substituted cyclohexene structure, the optical brightening agent may be used in the form of the di-acid, a di-salt, a mono-acid/mono-salt or a mixture thereof. 
     The importance of the one site of unsaturation in the cyclohexene ring is perhaps best displayed by the fact that the saturated analog does not exhibit optical brightening. According to one embodiment of the present invention, the C 21  dicarboxylic acid or salt thereof which is the optical brightening agent used in the composition of the present invention is of the formula: ##STR2## wherein x and y are integers from 3 to 9 and x and y together=12, Z is H or COOM 1  wherein one Z is hydrogen and the other is COOM 1  wherein M and M 1  are hydrogen, sodium, potassium, lithium, ammonium or mixtures thereof. According to a preferred embodiment of the present invention, the optical brightening agent is in the form of the di-potassium salt. 
     Any cationic fabric conditioning agent which is compatible with fabrics with which it will contact during the wash cycle of the laudering process, and which will impart softness and anti-static properties to such fabrics during the wash cycle, and which is compatible with the C 21  dicarboxylic acid, salts thereof and mixtures thereof and the non-ionic surfactant may be used. Similarly, any non-ionic surfactant which has detergent properties, is compatible with the cationic fabric conditioning agent, is compatible with the C 21  dicarboxylic acid, salts thereof and mixtures thereof and is compatible with the fabrics with which it will contact during the wash cycle of the laundering process may be used. Any suitable, compatible aqueous solvent system may be used to formulate the composition into a liquid form suitable for addition to the wash cycle of the laundering process. 
     The non-ionic surfactant and cationic fabric conditioning agent are preferably present in the weight ratio of 1:1 to 20:1. The preferred weight ratio of non-ionic surfactant to C 21  dicarboxylic acid (or salt or mixtures thereof) is 1:1 to 50:1. The preferred weight ratio of cationic fabric conditioning agent to C 21  dicarboxylic acid (or salt or mixtures thereof) is 1:1 to 10:1. 
     According to one embodiment of the present invention, the C 21  dicarboxylic acid, salt thereof or mixture thereof is present in the amount of about 0.4% to 10%, particularly about 2% to about 8%. From about 2% to about 6%, and from about 2% to about 5% have been found to be quite useful. From about 3% to about 5% has been found to be particularly useful. The compositions of the present invention may, if desired, contain effective amounts of dyes, fragrances, anti-soil redeposition agents, buffering agents, opacifiers, preservatives and the like, as well as other additives commonly found in liquid detergents, fabric softening and anti-static compositions. If desired, the compositions according to the present invention may also contain an effective amount of a compatible anti-microbial agent. 
     While a wide range of cationic fabric conditioning agents may be utilized, quaternary ammonium compounds have been found to be particularly useful. From about 0.5% to about 12%, particularly from about 5% to about 12% and especially from about 6% to about 10% have been found to be useful. 
     According to a further aspect of the present invention, the composition of the present invention is used to launder and impart conditioning including brightening to fabrics during the wash cycle of a laundering process by adding to the fabrics during the wash cycle an effective amount of a composition according to the present invention comprising an effective amount of a cationic fabric conditioning composition as above defined, an effective amount of a non-ionic surfactant having detergent properties with appropriate compatibility as above defined, an optical brightening amount of the C 21  dicarboxylic acid, salt thereof or mixture thereof as above defined, and a suitable compatible aqueous solvent system. 
     The non-ionic surfactant and cationic fabric conditioning agent are preferably present in the weight ratio of 1:1 to 20:1. The preferred weight ratio of non-ionic surfactant to C 21  dicarboxylic acid (or salt or mixtures thereof) is 1:1 to 50:1. The preferred weight ratio of cationic fabric conditioning agent to C 21  dicarboxylic acid (or salt or mixtures thereof) is 1:1 to 10:1. 
     According to one embodiment of the present invention, the C 21  dicarboxylic acid, salt thereof or mixture thereof is present in the amount of about 0.4% to 10%, particularly about 2% to about 8%. From about 2% to about 6%, and from about 2% to about 5% have been found to be quite useful. From about 3% to about 5% has been found to be particularly useful. The compositions of the present invention may, if desired, contain effective amounts of dyes, fragrances, anti-soil redeposition agents, buffering agents, opacifiers, preservatives and the like as well as other additives commonly found in liquid detergents, fabric softening and anti-static compositions. If desired, the compositions according to the present invention may also contain an effective amount of a compatible anti-microbial agent. 
     The cationic fabric conditioning agent may be a quaternary ammonium compound. Preferred ranges of cationic fabric conditioning agent are from about 0.5% to about 12%, from about 5% to about 12%, and from about 6% to about 10%. 
     Suitable quaternary ammonium compounds include those of the formula: ##STR3## wherein X is an anion, preferably a halide (particularly chloride) or methyl sulfate, R 1  and R 2  are each alkyl of 1 to 3 carbon atoms, R 3  is benzyl, alkyl of 1 to 3 carbon atoms, a polyethoxy moiety containing up to about 10 ethylene oxide units, alkoxypropyl or hydroxy substituted alkoxypropyl wherein the alkoxy moiety contains 12-20 carbon atoms, alkyl of 12 to 20 carbon atoms, alkyl amido wherein the alkyl moiety contains from 12 to 20 carbon atoms, and R 4  is alkyl of 12 to 20 carbon atoms, a polyethoxy moiety containing up to about 10 ethylene oxide units, or alkyl amido wherein the alkyl moiety contains 12-20 carbon atoms. 
     Particularly useful quaternary ammonium compounds include: 
     Tallowtrimethyl ammonium chloride 
     Tallowdimethyl (3-tallowalkoxypropyl) ammonium chloride 
     Ditallow dimethyl ammonium chloride 
     Ditallow dimethyl ammonium methyl sulfate 
     Eicosyltrimethyl ammonium chloride 
     Dieicosyldimethyl ammonium chloride 
     Dodecyltrimethyl ammonium chloride 
     Didodecydimethyl ammonium chloride 
     Tetradecyltrimethyl ammonium chloride 
     Ditetradecyldimethyl ammonium chloride 
     Pentadecyltrimethyl ammonium chloride 
     Dipentadecyldimethyl ammonium chloride 
     Didodecyldiethyl ammonium chloride 
     Didodecyldipropyl ammonium chloride 
     Ditetradecyldiethyl ammonium chloride 
     Ditetradecyldipropyl ammonium chloride 
     Ditallowdiethyl ammonium chloride 
     Ditallowdipropyl ammonium chloride 
     Tallowdimethyl benzyl ammonium chloride 
     Tallowdiethyl benzyl ammonium chloride 
     Dodecyltrimethyl ammonium methyl sulfate 
     Di(oxyethylene) tallow methyl ammonium chloride 
     Other cationic fabric conditioning agents of formula (I) are known and include variables wherein R 1  and R 2  are phenyl or hydroxy substituted alkyl of 1 to 3 carbon atoms. 
     Cationic imidazolinium compounds useful in the compositions of the present invention include those represented by the formula (II): ##STR4## wherein R 6  is alkyl of 1-4 carbon atoms, preferably from 1-2 carbon atoms, R 7  is hydrogen or alkyl of 1 to 4 carbon atoms, R 8  is alkyl of 8-25 carbon atoms, preferably at least 15 carbon atoms, R 5  is hydrogen or alkyl of 8-25 carbon atoms, preferably at least 15 carbon atoms, and X is an anion, preferably methyl sulfate or chloride. Particularly preferred are those compounds of formula (II) in which both R 5  and R 8  are alkyl of 16-25 carbon atoms, particularly 16-18 carbon atoms. 
     According to a further embodiment of the present invention, when the cationic fabric conditioning agent is a quaternary ammonium compound it may be a single quaternary ammonium compound or a mixture of quaternary ammonium compounds. The relative proportions in the mixture will be dependent upon the relative performance attributes of detergency, softening and static control which are desired. Particularly useful mixtures of quaternary ammonium compounds include: 
     ditallow dimethyl ammonium chloride with Di(oxyethylene) tallow methyl ammonium chloride 
     ditallow dimethyl ammonium chloride with methyl-1-oleyl-amidoethyl-2-oleyl imidazolinium methyl sulfate and 
     ditallow dimethyl ammonium chloride with diamido methyl ethoxylated ammonium methyl sulfate. 
     Any nonionic surfactant which is compatible with the cationic fabric conditioning agent and the other specific ingredients in a given composition may be used. Nonionic surfactants useful for this purpose are known in the art. Useful nonionic surfactants include the water-soluble products derived from the condensation of an alkylene oxide or equivalent reaction and a reactive-hydrogen hydrophobe. The hydrophobic compounds may be aliphatic, aromatic or heterocyclic, although the aliphatic and aromatic ones are preferred. The preferred types of hydrophobes are higher aliphatic alcohols and alkylphenols, although other hydrophobes may be used such as carboxylic acid, carboxamides, mercaptans, sulphonamides and the like. The ethylene oxide condensates with higher-alkylphenols and are a preferred class of nonionic compounds. Usually the hydrophobic moiety contains at least 6 carbon atoms, and preferably about 15 carbon atoms. The amount of alkylene oxide will vary considerably depending upon the hydrophobe, but as a general guide, at least 5 moles of alkylene oxide per mole of hydrophobe should be used. The upper limit of alkylene oxide will also vary. While ethylene oxide is the preferred oxyalkylating reagent, other lower alkylene oxides such as propylene oxide, butylene oxide and the like may be used or substituted in part for the ethylene oxide. Preferred hydrophobic moieties contain about 9 moles on the average of ethylene oxide, although greater amounts may also be employed. 
     Another preferred group of nonionic surfactants includes the class of oxyalkylated higher aliphatic alcohols. The fatty alcohols should contain at least 6 carbon atoms and preferably from 12-15 carbon atoms. Useful alcohols should be condensed with at least about 5 moles of ethylene oxide and preferably about 9 moles of ethylene oxide per mole of alcohol. A typical product is a C-12 to C-15 mixture of alcohols condensed with 9 moles of ethylene oxide. 
     The use of the C 21  dicarboxylic acid, salts thereof and mixtures thereof as the optical brightening agent is particularly surprising both because it was heretofore unknown that the acid, salts and mixtures would provide optical brightening and because they provide optical brightening in a cationic/non-ionic system. It is also surprising that the acid, salts and mixtures may be used in amounts as high as 10% because it is known in the art that when the amount of optical brightening agent rises over 1 to 2%, consumer negatives result in the product and large amounts of optical brightening agents are therefore not utilized in the prior art. It is therefore most surprising that effective whitening of fabrics is obtained with the dicarboxylic acid, salts thereof or mixtures thereof over the ranges described above.
