Abstract

The invention provides liquid hard surface cleaning compositions comprising multiple partial compositions held separately from each other in a multiple compartment container which is provided with a non-spray dispensing system. One partial composition comprises a peroxygen bleach compound, preferably hydrogen peroxide. The total composition comprises a multi-component thickening system of which the components are divided over the partial compositions in such a way that the total composition thickens on dispensing. Each partial composition has a pH at which the components in it are stable, while after mixing the total composition has a pH suitable for cleaning. The compositions preferably contain a quaternary imine salt bleach activator and a detergent surfactant. The number of partial compositions and of the compartments in the container is preferably 2.

Description

COM POSITIONS FOR CLEANING YOUR HARD PERFORMANCE FROM MULTIPLE COMPONENTS FIELD OF THE INVENTION The invention relates to liquid cleaning compositions consisting of at least two partial compositions, which are stored separately from each other in a simple container comprising at least two chambers, and which are mixed in use, a partial composition comprising a peroxygen bleach compound. The compositions are intended to clean and disinfect home surfaces and in particular, are well suited for use on surfaces which are not horizontal (i.e., slanted or vertical), as can be found, for example, in bathrooms and toilets.
BACKGROUND OF THE INVENTION The compositions that clean and disinfect for use on non-horizontal surfaces currently comprise solutions of alkali metal hypochlorite to be emptied, jetted or sprayed onto the surface. Such solutions are thickened in order to prevent them from dripping off the surface too quickly. In particular, for toilet cleaning purposes, they are often sold packaged in containers provided with a dispenser, so that they can be delivered to the surface when the container is tightened. Sometimes, such jets are mounted in the container in such a way, that the jet of liquid produced by the pressing action can be more easily directed to corners or under flanges, which can not easily be reached otherwise. A problem with such compositions is that the hypochlorite has an unpleasant odor and, when accidentally mixed with an acidic product, can release toxic amounts of chlorine gas. Other bleaching agents are known, in particular, peroxides. However, peroxides are often either unstable on storage in formulations or exhibit poor bleach performance at a pH at which they are stable on storage. Peroxide-based toothpastes and hair bleaching compositions have been formulated as weakly acidic peroxide solutions or gels, which are mixed with weakly alkaline, separate solutions or pastes, just before use. The known advantage of this product form is that, under acidic conditions, the peroxide is more stable to decomposition, but is more effective as a bleaching agent under alkaline conditions. Other two-part peroxide-based compositions are described in JP-A-60/038497 (LION BRANDS), which refers to a two-part draining, foaming cleaning composition, which comprises: a) 0.5- 50% by weight of hydrogen peroxide; b) alkali, having an alkalinity of 0.1-50% based on sodium hydroxide; c) surface active agent in (a) or (b), and, d) terpene alcohol / cyclic terpene alcohol in (a) or (b). The compositions (a) and (b), including the surfactants and the terpene are sequentially or simultaneously dosed into a toilet bowl and passed to the drain, where the composition produces a foam body that acts to clean, or if necessary unlock drain. Other forms of simultaneous delivery of two components are known. Thus, US-A-3, 760, 986 discloses a dispensing bottle for dispensing two separate fluids at a common point. Such a bottle is formed with an opening in the upper part and a divider that extends through the inside of the bottle to define two compartments, which provides dual reservoirs for fluids. The apparatus disclosed further comprises a pump means for simultaneously removing the fluid from each compartment, via separate drainage tubes and discharging the fluid to a common point. This device allows an alkaline and an acidic material to be stored separately and atomized from a single unit to a common point. WO 95/16023 describes a container comprising two chambers or tanks, one containing a liquid acid or neutral composition comprising a peroxide compound and the other containing a liquid alkaline composition. The container is provided with a spray system capable of either producing a single spray of a mixture of the two components or two simultaneous sprays of each component directed to the same point on one surface, after which the components are mixed on the surface . The product is delivered as fine droplets, which coalesce on the surface, which provides easy and complete mixing of the two compositions. It is described that the compositions may thicken as they contain or may contain a thickening system, which thickens with mixing. The thickening system is particularly adjusted to improve spray characteristics and prevent respiratory irritation caused by very fine droplets. The examples show that both components are thickened before atomization. WO 97/31087 describes a container comprising two chambers or reservoirs, containing one, a liquid composition comprising a peroxygen blasting agent and the other containing a liquid composition comprising a former or chelating agent, and containing at least one of these liquids is a pH adjusting agent, which upon mixing of the liquids brings the pH of the mixture to a value at which the peroxygen bleach effectively cleanses as well as is stable. Preferably, the peroxygen bleach is either a perished or a persal and the pH is between 9.0 and 1 .5. The two liquid compositions are mixed on delivery to the surface, preferably by a spray system. A similar system is described in WO 98/23533, in which a combination of hydrogen peroxide and an N-alkyl tertiary ammonium acetonitrile salt of one chamber and an alkaline solution of the other chamber can be delivered to a surface by atomization These two-component peroxide cleaning systems of the prior art have the disadvantage that a spray system is only capable of delivering a limited amount of product to a surface and is unable to reach hard to reach places, because the container It should generally be held vertically. Consequently, they are less suitable for toilet flushing purposes. Moreover, atomization systems, such as spray atomization heads and pump atomizations, are relatively expensive, in particular, those that are suitable for multi-compartment containers.
BRIEF DESCRIPTION OF THE INVENTION Therefore, an object of the present invention is to provide liquid, hard surface cleaning compositions, which comprise a peroxygen bleach, are stable in storage and even provide good cleaning and disinfection on the application to a surface. Another object of the invention is to provide liquid, hard surface cleaning compositions which can be easily applied to a surface using a non-atomizing dispensing system and are sufficiently thick on the surface to be suitable for cleaning non-horizontal surfaces, particular, toilets. A further object of the invention is to provide hard surface cleaning compositions, in which the components are not stable in the storage in the presence of one another, they are kept separate from each other until the moment of dispensing the composition on the surface .
Accordingly, the invention provides liquid cleaning compositions consisting of at least two liquid partial compositions, which are held separated from one another in a single container, comprising at least two chambers, reservoirs or compartments (henceforth further referred to as "chambers") and a non-atomizing dispensing system, the at least one partial composition comprising a peroxygen bleach compound, said cleaning composition comprising a multi-component thickener system, of which the components are divided at least two partial compositions, so that upon mixing the partial compositions in the delivery to the surface to be cleaned, the combination of the components of the thickening system causes the final composition to thicken and adhere to the non-horizontal surfaces. Each partial composition has a pH such that the components of that partial composition are stable in storage, while after the mixing of the partial compositions, the final composition has a pH suitable for cleaning. Additionally, the invention provides thickened liquid cleaning compositions obtained by mixing two or more partial compositions on delivery through a non-atomizing dispensing system, at least a partial composition comprising a peroxygen bleach compound and at least one two partial compositions, each comprising one or more components (but not all) of a multi-component thickener system, so that the thickening is obtained by mixing the partial compositions, each partial composition having a pH, so that the com ponents of that partial composition are stable in storage, while after mixing the partial compositions, the final composition has a pH suitable for effective cleaning. In addition, the invention provides a container comprising two or more chambers, each provided with an outlet opening for dispensing the contents of each chamber, which together, form part of a non-atomizing dispensing system, holding said container with the positions partial liquid described above.
DETAILED DESCRIPTION OF THE INVENTION For the purposes of this invention, a "partial composition" is defined as a component, or a mixture of more, but not all, components of the final composition, said component or mixture is held in a separate chamber of the container containing the total composition. Two or more partial compositions together form the final cleaning composition according to the invention. A suitable container for holding the cleaning compositions according to the invention has at least as many separate chambers as the number of partial compositions making the total composition. Such a container may have an outer wall that encompasses all the chambers, which are separated from one another by dividing walls within the container or, alternatively, may be formed by a plurality of separate containers, equivalent to the chambers, which are held together by some external means, such as a connecting part. of the walls or an adhesive sleeve that surrounds them, in such a way that they can be held and handled like a container. A dispensing system is provided in which a chamber is provided with an outlet opening through which the partial composition is dispensed. These outlet openings can all lead to a separate mixing chamber, in which the dispensed quantities of the partial compositions are mixed just before being applied to the surface through a dispensing opening in the mixing chamber. Alternatively, the exit openings can all lead to the exterior of the container in such a way that the dispensed quantities of the partial compositions are all applied simultaneously to the same area of the surface, in order to mix, at the same time. which are applied to the surface or immediately after application on the surface. For this purpose, the outlet openings will generally be positioned in close proximity to one another, so that all partial compositions are emptied, jetted, into the same area of the surface in one operation. The outlet openings can be provided with a nozzle system designed to further improve the mixing of the partial components upon leaving the container. Dispensing systems, such as described above and similar to those known in the art, fall within the term "non-atomizing dispensing systems". In general, they are characterized by the absence of the so-called "spray atomization heads or spray heads of the pump" and, unlike such spray heads, operate without the application of external pressure on and above the pressure environment or by pressure exerted by the operation of decreasing the total contents of the container, such as by tightening the flexible walls of a container as is well known for dispensing liquid hypochlorite toilet cleaners, liquids for manual dishwashing and similar liquid products. For practical reasons, such ease of construction and handling, the container preferably comprises no more than two chambers, each maintaining a partial composition, said compositions together making the final cleaning composition according to the invention. This implies that for the same reasons, the cleaning compositions according to the invention are preferably made of two partial compositions. Additionally, the container may comprise a mixing chamber as noted above. The quantities of the partial compositions that make up the final composition do not necessarily need to be equal, provided that care is taken that the concentration of each component in each of the partial compositions is chosen so that upon mixing the quantities provided of the partial compositions, the correct concentration of each component in the final composition is present. The volume of each chamber of the container is adapted to the amount of the parity composition in that chamber, which is required to make the total amount of the final composition in the container. The total liquid volume of the final composition to be obtained from the container in general will be approximately equal to the total volume of the container, excluding the volume of the mixing chamber, if present. The dispensing system, for example, the dispensing or outlet openings of the container chambers, is dimensioned so that a simple dispensing operation dispenses the correct quantities of all the partial compositions necessary to properly make the final composition., in which each component is present in the desired concentration. Although there is no theoretical limitation such as the size and shape of the containers, for practical purposes, such ease of handling and dispensing, the containers will generally have a total volume of 0. 1 - 2 liters, preferably at least 0.25 I, but preferably not more than 1.5. In addition, for practical purposes, two-chamber containers preferably have chambers of approximately equal volume, holding approximately equal quantities of each of the two partial compartments. Suitable containers have been described in co-pending British patent applications nos: 98 15659.9, 98 1 5660.7 and 98 1 5661 .5. The peroxygen bleach compound can be any peroxide or peroxide generating system known in the art. Well-known examples are: hydrogen peroxide, various organic or inorganic peracids, for example perbenzoic acid and substituted perbenzoic acids, various aliphatic peroxyacids and diperoxy acids, such as peracetic acid, diperoxy-dodecanedioic acid, N, N-phthaloylamino-peroxycaproic acid (PAP ), various organic or inorganic persalts, such as monoperoxosulfates, perborates, perfosphates, persilicates, etc. Such peroxygen bleach compounds can be used in combination with bleach activator compounds to enhance their bleaching activity. Many require activating compounds to obtain an appropriate bleaching action. Preferred peroxygen bleach compounds are hydrogen peroxide, peracetic acid and monoperoxosulfate salts of alkali metals or alkaline earth metals. The amount of peroxygen compound is preferably chosen so that the final composition will contain 0.05-10% active oxygen, more preferably 0.1-5%, most preferably at least 0.5%. The partial composition containing the peroxygen compound has a pH at which the peroxygen compound is stable in storage. Many peracids and persalts have limited stability in alkaline solutions and therefore, a partial composition containing these will preferably have a pH of at most 8, more preferably at most 7.5, most preferably 7 or below. The hydrogen peroxide is reasonably stable up to pH 10, although for longer term stability, the pH should not exceed, preferably, 9.5, more preferably at most 9.0, most preferably at most 8.0. Many bleach activators are found among amylas and acylated amides (in particular, acetylated) of which tetracetyl-ethylenediamine (TAE D) is probably the best known example. Well-known examples of peroxide / activator combinations are perborate / TAED and percarbonate / TAED. Useful bleach activating compounds are cationic nitriles, such as: N-alkyl ammonium acetonitriles, described in EP-A-0 303 520, EP-A-0 458 396, EP-A-0 464 880, WO 96 / 40661, WO 98/23533, DE 1 96 29 1 59 and EP-A-0 790 244 and the cyanopyridinium and pyridine-N-oxide compounds described in EP-A-0 806 473 and EP-A-0 819 673 Similarly, useful cyano activating compounds are described in EP-A-0 819 673 and DE 196 09 955. Particularly useful bleach activator compounds are imas, such as the sulfonimines described in US-A-5, 041, 232, US-A- and US-A-5,047, 163 and quaternary imine salts (imine quats). Imine quats are described generally and many specific examples given in US-A-5,360,568, US-A-5,360,569 and US-A-5,478, 357. Further examples thereof are described in WO 96/34937, WO 97 / 1 0323, WO 98/16614 and US 5, 71 0, 1 1 6. Suitable sulfonimines have the general structure below: R 1 R2C = N-SO 2 -R 3 wherein: R 1 can be hydrogen or a phenyl group, aryl, heterocyclic, substituted or unsubstituted alkyl or cycloalkyl; R 2 may be hydrogen or a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl group, or a keto, carboxylic, carboalkoxy or R 1 C = N-SO 2 R 3 group; R3 may be a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl group, or a nitro, halo or cyano group; R1 with R2 and / or R2 with R3 can each form a cycloalkyl, heterocyclic or aromatic ring system. Suitable quaternary imine salts have the general structure below: R1 R2C = N + R3R4X- wherein: R1 and R4 can be hydrogen or substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl groups; R 2 may be hydrogen or a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl group, or a keto, carboxylic or carboalkoxy group; R3 may be a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl group, or a nitro, halo or cyano group; R1 with R2 and / or R2 with R3 can respectively form a cycloalkyl, heterocyclic or aromatic ring system. X 'is a counter-ion, which is stable in the presence of peroxide compounds. The quaternary imine salts (imine quats) are those that have the structure of 3,4-dihydro-isoquinolinio below: wherein R5 and R6 may be hydrogen or a phenyl, aryl, heterocyclic ring, alkyl, substituted or unsubstituted cycloalkyl of C1-C30, or a nitro, halo, cyano, alkoxy, carboxylic and carboalkoxy radical, and R4 may be a phenyl, aryl, heterocyclic ring, substituted and unsubstituted C 1 -C 30 alkyl and cycloalkyl radical. R5 can represent more than one substituent in the aromatic ring. Representative examples of compounds according to the general structure (having an R5) are given in the table below.
Particularly useful are imine quats, wherein R 4 is an alkyl group, such as methyl or a substituted alkyl group and wherein R 6 is hydrogen or a C 1 -C 5 alkyl group or a phenyl group. Also useful are those compounds in which R 5 represents one or two methoxy groups, such as two methoxy groups in the 6 and 7 position. Examples of preferred imines quats are salts of N-methyl-3,4-dihydroisoquinoline and q corresponding uats in which R6 are methyl or ethyl, respectively. These are particularly advantageous when used in combination with hydrogen peroxide. The imine quats have only storage stability limited to high pH and therefore, the partial composition containing these imines should preferably have a pH below 8, more preferably when at most 7, m and preferably between 2.0 and 6.5. If used, the imine quat is generally present in an amount from 0.001 -1.0%, preferably 0.01 -5%, most preferably not more than 2%. The molar ratio of peroxygen compound to quat mine will vary, generally, from 1: 500: 1 to 1: 2, preferably from 1: 50: 1 to 1: 1, more preferably from 60: 1 to 2: 1. . If a bleach activating compound is used, it may be a component of the same partial composition as the peroxygen compound, provided that both have sufficient stability in the cement together at a pH that is suitable for partial composition, considering the pH requirements of the final composition. Otherwise, the activator and peroxygen compound are separately maintained in different partial compositions. In this manner, the partial compositions containing hydrogen peroxide and an imine quat together preferably have a maximum pH of 6.5, more preferably at most 6. In order to obtain a thorough mixing of the partial compositions on the dispensing of the partial compositions, all should be thin before mixing, that is, have a viscosity of 20 mPa.s or less, preferably 10 mPa.so less, more preferably at most 5 mPa.s (HaakeMR R20 Viscosimeter, 25 ° C, see cutting speed: 21 s' 1). Although the viscosities of all partial compositions before mixing do not necessarily have to be the same, they are preferably not far apart since this may influence the relative amounts of the partial compositions dispensed in a dispensing operation and the mixing thereof. A difference in viscosity can be compensated for by adjusting the dispensing means, for example, by a dimensioning correspondingly different from the dispensing openings of the corresponding chambers. During or immediately after application to the surface, the cleaning composition thickens sufficiently to adhere to the surface and prevent it from dripping off the non-horizontal surface before proper cleaning is obtained. This thickening is caused by the mixing of the components of said multi-component thickener system, the components of which are divided over at least two partial compositions. Preferably, the viscosity of the final composition after dispensing is at least 50 mPa. s, more preferably at least 100 mPa.s. On the other hand, the viscosity is preferably not more than 1000 mPa.s. (measurement conditions: see above). A large number of multi-component thickening systems is known in the art. To be suitable for the cleaning compositions according to the invention, preferably at least one component should be stable in storage in the same partial composition as the peroxygen bleach compound. The total thickener system should be sufficiently stable in the final composition to allow the composition to thicken and remain on the surface sufficiently to perform its cleaning action. Many thickener systems have been used in thickened hypochlorite bleach compositions. Such systems often consist of two or more detergent surfactants, or one or more such surfactants in combination with an electrolyte, such as an inorganic salt. Many thickener systems comprise as one of its components a tertiary amine oxide, an ethoxylated fatty alcohol or other non-ionic surfactant and like other components, an anionic surfactant. Examples of such thickening systems are described in EP-A-079697, E-PA-1 1 0544, WP-A-137551, EP-A-145084, EP-A-24461 1, EP-A-635568, WO95 / 0861 1 , DE-A-1 9621048 and the literature cited in these patent applications. Other suitable thickener systems comprise polymeric substances, which in solution thicken in response to an increase in pH or electrolyte concentration. Examples of the same are acrylic acid polymers known for their thickening properties, such as those sold under the trademark "Acusol". Examples of various thickening systems, preferred ranges of the relative amounts of their components (in% of the total mixture of surfactants) and their possible division into partial compositions, are given below: A partial composition Another partial composition Nonionic Surfactant (60-30) Inorganic Salt Cationic Surfactant (40-70) Cationic Surfactant (10-30) Anionic Surfactant (90-70) Inorganic Salt Anioic Surfactant (90-70) Cationic Surfactant (10-7) -30) Inorganic Salt Amine Oxide Surfactant (85-60) Anionic Surfactant (15-40) Nonionic Surfactant (60-30) Inorganic Salt Anionic Surfactant (40-79) Anionic Surfactant (90-70) Inorganic Salt Cationic Surfactant (10-30) Cationic Surfactant (95-85) Anionic Surfactant (5-15) Inorganic Salt Polyacrylate Latex Alkaline pH Adjustment Agent For some multi-component thickener systems, the components may all be present in a partial composition, if at least one of the components is present therein at a concentration below the concentration necessary to cause thickening of the system and the rest of that component is present in another comp partial possession. Then, upon mixing the partial compositions, the concentration of that component in the final composition is increased to the level required to cause thickening. Detergent surfactants often play an important role in thickening systems as noted above. Independent of them, they are preferably added in addition to their wetting properties on hard surfaces and their cleaning properties. In this way, surfactants are preferably present even if a thickener system with a non-surfactant base is used. If not required for thickening, the total surfactant content is preferably between 0. 1 and 20%, more preferably between 0.5 and 10%, most preferably at most 7%. If it is part of the thickening system, the minimum total amount of surfactant will be at least 0.5%, preferably at least 1%. The surfactants can be chosen from a wide range of anionic, nonionic, cationic, amphoteric or zwitterionic surfactants well known in the art. Suitable anionic surfactants are, for example, water-soluble salts, in particular alkali metal, alkaline earth metal and ammonium salts, organic sulfate esters and sulphonic acids having in the molecular structure a C 8 -C 22 alkyl radical or a C10-C22 alkaryl radical. Examples of such anionic surfactants are alcohol sulfate salts, especially those obtained from fatty alcohols derived from tallow glycerides or coconut oil; alkyl benzene sulphonates, such as those having a C9-C1 5. Examples of such anionic detergents are alkyl sulfate alcohol group attached to the benzene ring; secondary alkanesulfonates; sodium alkyl glyceryl ether sulfates, especially those ethers of the fatty alcohols derived from tallow and coconut oil; monogul sulfates of sodium fatty acid, especially those derived from coconut fatty acids; sulfate salts of ethoxylated fatty alcohol of 1-6 EO; salts of sulfates of alkylphenol ethoxylated of 1 -8 EO in which the alkyl radicals contain 4-14 C atoms; the reaction product of gaseous acids esterified with isonic acid and neutralized with sodium hydroxide. Preferred water-soluble synthetic anionic surfactants are alkyl benzene sulfonates, olefin sulfonates, alkyl sulfates and monoglyceride sulfates of higher fatty acids. On the other hand, the fatty acid soaps are not very suitable for use in the cleaning compositions according to the invention. A special class of anionic surfactants, which can be used in cleaning compositions according to the invention are hydrotropes, which are known in the art, specifically, for their thickening or liquid structuring capabilities. Well-known examples of such compounds are alkali metal salts of toluene-, xylene- and cumene-sulphonic. Suitable nonionic surfactants can be broadly described as compounds produced by the condensation of alkylene oxide groups, which are hydrophilic in nature, with an organic hydrophobic compound, which may be aliphatic or alkylaromatic in nature. The length of the hydrophilic or polyoxylalkylene radical, which is attached to any particular hydrophobic group, can be easily adjusted to produce a water-soluble or water-dispersible compound having the desired whiteness between hydrophobic and hydrophobic elements. Particular examples include in the condensation product of straight chain or branched chain aliphatic alcohols, having 8-22 C atoms with ethylene oxide, such as coconut oil / ethylene oxide fatty alcohol condensates having from 2 to 15 moles of ethylene oxide per mole of coconut alcohol; condensates of alkylfenoles, whose alkyl group contains 1-16 carbon atoms with 2 to 25 moles of ethylene oxide per mole of alkylphenol; condensates of the reaction product of ethylenediamine and propylene oxide with ethylene oxide, the condensates containing from 40 to 80% of ethyleneoxy groups by weight and having a molecular weight of from 5,000 to 1,000,000. Other examples are: tertiary amine oxides of general structure RRRNO, where one R is an alkanoyl group of C 8 -C 22 (preferably C 8 -C 8), and the other Rs are each hydroxyalkyl or C 1 alkyl groups C5 (preferably C 1 -C 3), for example, dimethyldodecylamine oxide; tertiary phosphine oxides of structure RRRPO, where one R is a C8-C22 alkyl group (preferably C8-C18) and the other Rs are each hydroxyalkyl or C1-C5 alkyl groups (preferably C1-C3) , for example, dimethyl dodecylphosphine oxide; dialkyl sulfoxides of RRSO structure, where one R is a C 10 -C 18 alkyl group and the other is methyl or ethyl, for example, methyltetradecyl sulfoxide; fatty acid alkylolamides; alkylene oxide condensates of fatty acid alkyl amides and alkyl mercaptans. Ethoxylated aliphatic alcohols are particularly preferred. Amine oxides are also very suitable because they are mixed very well with inorganic electrolytes. Amphoteric surfactants are derivatives of secondary and tertiary aliphatic amines, containing a C8-C18 alkyl group and an aliphatic group substituted by an anionic water-solubilizing group, for example, sodium 3-dodecylamino propionate, 3-dodecylaminopropane sulfonate sodium and N-2-hydroxydecyl-N-methyl taurate sodium. Suitable cationic surfactants are quaternary ammonium salts having at least one C8-C22 hydrocarbon group, for example, dodecyltrimethylammonium bromide or chloride, cetyltrimethylammonium bromide or chloride, didecyl dimethyl ammonium bromide or chloride. Many quaternary ammonium salts have antimicrobial properties and their use in cleaning compositions according to the invention leads to products having disinfecting properties. They are used in the cleaning compositions according to the invention in an amount of 0-1.0%, preferably 0. 1 -8%, more preferably 0.5-6%.
Suitable zwitterionic surfactants are derivatives of aliphatic ammonium, sulfonium and quaternary phosphonium compounds, which have an aliphatic group of C 8 -C 8 and an aliphatic group substituted by an anionic group solubilizing in water, for example 3- (N, N -dimethyl-N-hexadecylammonium) propane-1-sulfonate beta-one, 3- (dodecyl-methyl-sulfonium) -propane-1-sulfonate-betaine and 3- (cetylmethyl-phosphonium) -ethane-sulfonate-beta-one. Additional examples of suitable surfactants are given in well-known textbooks "Surface Active Agents" (active surface agents), Volume I by Schwartz and Perry and "Surface Active Agents and Detergents (Active Surface Agents and Detergents), volume II by Schwartz, Perry and Berch The surfactants, which are stable in storage in combination with the peroxygen compound, can be combined with the peroxygen compound in the same partial composition.The surfactants, which do not have such stability, should be part of the Another composition or partial compositions In this way, the quaternary ammonium halides preferably do not combine with the peroxygen compound in the same partial composition, due to the possible decomposition of the peroxygen compound by the halogenide ion. in particular for bromides and iodides The partial composition containing the perox bleach compound geno also preferably contains a sequestering agent to bind metal ions, particularly transition metal ions, the Cua could otherwise destabilize them the peroxygen compound.
Suitable sequestering agents are, for example, ethylene lendiamine tetraacetate, amino polyphosphonates (such as those in the DEQ U ESTM R range). A wide variety of organic and inorganic polyhydric acids and salts can also be optionally employed. Preferred sequestering agents are selected from dipicolinic acid, ethylenediamtetraacetic acid (EDTA) and its salts, hydroxyethylidene diphosphonic acid (Dequest 201 0), ethylenediaminetetra (methylene phosphonic acid) (Dequest 2040), diethylene triamine petna acid (methylene phosphonic) (Dequest 2060). Such sequestering agents are generally used in an amount of 0.01 -5%, preferably 0.05-2%. Electrolytes, in particular inorganic salts, are part of many thickener systems. Suitable salts are carbonates, sulfates and alkali metal halides. The halides, especially bromides and iodides, are preferably kept separate from the peroxygen compounds, ie in different partial compositions. The electrolytes are used in an amount of 0-20%, preferably 0-15%, more preferably 0-10%. Apart from particularly suitable sequestering agents for binding transition metal ions, as mentioned above, the cleaning compositions according to the invention can also usefully contain a sequestering agent suitable for binding Ca ions. Such a sequestering agent may be contained in any of the partial com positions. Sequestering agents suitable for their purpose are well known in the art and include such compounds as: tripolyphosphate, pyrophosphate and ortho-phosphate of alkali metals, sodium nitrilotriacetic acid salt, sodium methylglycine-diacetic acid salt, alkali metal citrate, carboxymethyl malonate, methyl glycine diacetic acid, carboxymethyloxysuccinate, tartrate, mono- and di-succinate and oxydisuccinate. As many peroxygen compounds are stable in storage at a lower pH than that at which they develop their maximum bleaching effect, a partial composition that does not contain the peroxygen compound, preferably contains enough alkali to raise the pH of the final composition of the level required for storage stability to that required for effective bleaching. Preferably, the pH of the final composition should be 9.0 or greater, more preferably at least 9.5, even more preferably at least 10.5, most preferably at least 11.0. Particularly suitable alkaline materials are alkali metal hydroxides and carbonates. The final cleaning compositions are aqueous liquids and the partial compositions preferably also are all aqueous liquids, although some or all may additionally contain organic solvent. Such organic solvents must be sufficiently stable with peroxygen bleach, in order not to interfere with the cleaning process in the final composition. Furthermore, not all thickener systems will thicken sufficiently in the presence of an organic solvent and consequently, thickener systems will have to be selected. For most cleaning purposes, the presence of an organic solvent will not be required.
Other minor components may be present in the cleaning compositions according to the invention to improve their cleaning or disinfecting properties, such as antimicrobially active compounds other than the aforementioned quaternary ammonium salts, or to improve their appearance to the consumer. Examples of the latter are perfumes and dyes. Some perfume components, such as certain essential oils, are known in the art to also have antimicrobial properties and thus can provide a double activity. For the purposes of the present invention, a component or a partial composition will be considered to be stable in storage if it still has at least 50% of its activity or initial activities after 10 days of storage at 20 ° C. Depending on the components in the partial composition, such activities may comprise: surfactant activity, thickener activity, disinfectant activity, active oxygen content, bleach activator activity, etc. For a stability in the preferred storage, the activity or activities should be at least 50% after 30 days of storage, more preferably after 60 days of storage at 20 ° C. All percentages expressed herein are percentages by weight of the final composition unless otherwise indicated.
Examples l-XI The following aqueous cleaning compositions were prepared, each consisting of equal amounts of the partial compositions a) and b). All compositions contain N-methyl-3,4-dihydroisoquinolinium tosylate, such as imine quat. All were stored in a dual chamber container consisting of two separate "container halves" held together by an adhesive sleeve surrounding them and by the one-piece dispensing nozzle system. The percentages in the examples are given by weight of the partial composition to which they belong, the rest being demineralized water. In this way, the percentages in the final composition are half of these values.
