Description

Description of the invention

The invention relates to liquid cleaning compositions consisting of at least two partial compositions which are kept separate from each other in one container having at least two chambers, which compositions are mixed during use and one part composition contains a peroxy bleach compound.

The compositions are intended for cleaning and disinfecting household surfaces, and are particularly suitable for use on non-level surfaces (e.g., sloping or vertical) such as in bathrooms and toilets, for example.

Known cleaning and disinfecting compositions for use on non-level surfaces include alkali metal hypochlorite solutions and are designed to be poured, sprayed or sprayed onto the surface. Such solutions are thickened which prevents too fast drainage. Toilet cleaners in particular are often sold packaged in containers provided with a spout so that they can be applied to the surface by pressing on the container. Sometimes the gutters are fitted in the container so that the liquid spurt from pressing the package can more easily be directed towards the corners or under the rim of the shell, which places cannot be easily reached otherwise.

A problem with such compositions is that hypochlorite has an unpleasant odor, and when it is accidentally mixed with an acidic product it can release toxic amounts of chlorine gas. Other bleaching agents are known, especially peroxides. However, peroxides are often storage unstable and exhibit poor bleaching performance at the pH values at which they are storage stable.

Toothpaste compositions and peroxide based hair bleaching compositions are formulated as weakly acid peroxide solutions or gels which are mixed with separate weakly basic solutions or pastes before use. A known advantage of such products is that the peroxide is more resistant to decomposition under acidic conditions, but is more effective as a bleaching agent under alkaline conditions.

Other two-part peroxide-based compositions are disclosed in JP-A-60/038497 (LION BRANDS) which relates to a foaming two part drip cleaning composition comprising:

a) 0.5-50% by weight of hydrogen peroxide,

b) a base with a basicity of 0.1-50%, calculated as sodium hydroxide,

c) the surfactant in (a) or (b) i

d) terpene alcohol / cyclic terpene alcohol in (a) or (b).

Compositions (a) and (b) containing surfactants and terpenes are sequentially or simultaneously dispensed into the toilet bowl and flow down a drain where they produce a working cleansing foam, or drain release if necessary.

Other forms of simultaneous delivery of two components are known. US-A-3760986 discloses a dispensing bottle for dispensing two separate fluids at a common point. Such a bottle has an opening at the top and a partition extending along the inside of the bottle to define two compartments constituting two fluid receptacles. The disclosed devices further include a pump element for simultaneously evacuating fluids from each container, via separate discharge tubes, and delivering fluid to a common point. This allows the alkaline and acidic material to be stored separately and sprayed from one container to a common point.

WO 95/16023 discloses a container containing two chambers or reservoirs, one with a liquid acidic or neutral composition containing a peroxy compound and the other with a liquid alkaline composition. The container is provided with a sprinkler system allowing either a single stream of a mixture of the two components to be produced, or two simultaneous jets of each component aimed at the same point on the surface where the compositions mix. The product is supplied as fine coalescing droplets on the surface which allows for easy and complete mixing of the two compositions. The compositions are said to be thickened because they are or contain a thickener system which causes a thickening upon mixing. The thickening system is particularly important to improve spray performance and to prevent fine droplets from irritating the respiratory system. The examples illustrate an embodiment where both components are concentrated prior to spraying.

PL 192 953 B1

WO 97/31087 discloses a container containing two chambers or tanks, one with a liquid composition containing a peroxy bleach compound and the other with a liquid composition containing a filler or chelating agent, and at least one of these liquids includes a pH adjusting agent which, when mixing the liquid, provides The pH of the mixture to a value at which the peroxy bleach is effective in cleaning and at the same time being stable. Preferably, the peroxy bleach is either peracid or persalt, and has a pH between 9.0 and 11.5. The two liquid compositions are mixed on delivery to a surface, preferably by a spray system. A similar system is described in WO 98/23533 where a combination of hydrogen peroxide and an N-alkylammoniumacetonitrile tertiary salt from one compartment and the alkaline solution from the other compartment can be delivered to the surface by spraying.

These prior art two-component peroxide cleaning systems have the disadvantage that the spray system is only capable of delivering a limited amount of product to the surface and is not capable of delivering product to hard-to-reach locations since the container generally has to be kept upright. For this reason, they are less suitable for cleaning toilets. Moreover, spray systems such as trigger spray heads and spray pumps are relatively expensive, especially those suitable for multi-reservoir containers.

It is an object of the invention to provide liquid hard surface cleaning compositions, peroxygen bleach containing compositions which are storage stable and provide good cleaning and disinfecting performance when applied to a surface.

Another object of the invention is to provide liquid hard surface cleaning compositions that can be easily applied to a surface with a non-spray dispensing system and are sufficiently dense on the surface to be suitable for cleaning non-level surfaces, especially toilets.

It is a further object of the invention to provide liquid hard surface cleaning compositions whose components, which are unstable in the presence of others, are kept separate from each other until the composition is delivered to the surface.

The invention relates to a liquid cleaning composition consisting of at least two liquid partial compositions which are kept separate from each other in a single container having at least two chambers and a non-spraying dispensing system, and the at least one partial composition comprises a peroxygen bleach compound characterized by this that (a) the amount of peroxygen bleach compound is such that the final composition contains 0.05 to 10 wt% active oxygen, wherein the peroxy bleach compound is selected from the group: hydrogen peroxide, organic or inorganic peracids, aliphatic peroxy and diperoxy acids, and inorganic salts;

(b) the cleaning composition comprises a multi-component thickening system, the components of which are distributed between at least two partial compositions such that each partial composition has a viscosity of 20 mPa.s or less, and when the partial compositions are mixed, the final composition has a viscosity of at least 50 mPa.s , and (c) a multi-component thickening system, the components of which are divided into at least two partial compositions, comprising:

(i) two or more different detergent surfactants, or (ii) one or more such surfactants in combination with an electrolyte, preferably an inorganic salt.

Preferably, each partial composition has a pH to ensure the storage stability of its components, and after the partial compositions are mixed, the final composition has a pH suitable for cleaning.

Preferably the amounts of the partial compositions are all equal, and it is also preferred that the composition consists of two part compositions.

Preferably, in the composition according to the invention, the peroxide bleach is selected from the group consisting of hydrogen peroxide, peracetic acid and monosulfate salts of alkali metals or alkaline earth metals, and particularly preferably contains hydrogen peroxide as the peroxide bleach compound.

In this case, it is preferred that the partial composition containing hydrogen peroxide has a pH of 10 or less.

PL 192 953 B1

In another embodiment of the compositions of the invention, the at least one partial composition comprises a bleach activator, preferably the bleach activator is a quaternary imine salt.

Preferably, the peroxide bleach compound and the bleach activator are contained in the same partial composition.

In another preferred embodiment of the invention, the at least one partial composition comprises a cationic surfactant.

Preferably, one of the partial compositions contains an amount of the alkaline compound in an amount sufficient to raise the pH of the final composition upon mixing to 9 or above.

Thus, the invention provides liquid cleaning compositions consisting of at least two liquid partial compositions held separate from each other in a single container having at least two chambers or tanks (hereinafter referred to as "chambers) and a non-spattering dispensing system, at least one partial composition containing a peroxygen compound. a bleach cleaning composition comprising a multi-component thickening system whose components are divided between at least two partial compositions so that when the partial compositions are mixed while they are delivered to the surface to be cleaned, the combination of the components of the thickening system causes the final composition to thicken and stick to non-level surfaces.

The invention provides thickened liquid cleaning compositions prepared by mixing two or more partial compositions while being delivered through a non-spray dispensing system, and at least one partial composition comprises a peroxy bleach compound and at least two partial compositions each containing one or more (but not all) ingredients. a multi-component thickening system such that thickening occurs by mixing the partial compositions, and each partial composition has a pH such that the components of the partial compositions are storage stable, whereas, after mixing the partial compositions, the final composition has a pH suitable for effective cleaning.

The compositions of the invention are packaged in a container having two or more chambers, each of which is provided with an outlet for discharging its contents, the openings together forming part of a non-spraying dispensing system, such container containing the above-described liquid partial compositions.

For the purposes of the invention, the term "partial composition is defined as an ingredient or blend of some, but not all, ingredients of the final composition, which ingredient or blend is kept in a separate compartment of a container containing the entire composition. Two or more partial compositions together form the final cleaning composition of the invention.

A container suitable for containing the cleaning compositions of the invention has at least as many separate chambers as the partial compositions constitute the final composition. Such a container may have one outer wall surrounding all the chambers, separated from each other by partial walls inside the container, or alternatively it may be constructed of a plurality of separate containers, corresponding to chambers which are held together by external means, such as joining a portion of the walls or adjacent to the surrounding area. sleeves in such a way that they can be held and handled as if they were one container. Each of these chambers has a dispensing system with an exit port through which partial compositions are dispensed. These exit openings may all lead to a separate mixing chamber in which metered aliquots of the partial compositions are mixed immediately prior to application to the surface through a dosing opening in the mixing chamber. Alternatively, all of the exit openings may lead to the exit opening of the container such that the metered amounts of the partial compositions are simultaneously applied and applied to the same surface area and mix when applied to a surface or immediately after application to a surface. The exit holes will generally be positioned close to each other such that all partial compositions are poured, sprayed onto the same surface area in one operation. The exit openings may be provided with an array of nozzles designed to further improve the mixing of the partial ingredients on exiting the container. Dispensing systems as described above and the like are known in the art and are referred to as "non-spray dispensing systems." They are generally characterized by the absence of a so-called spray discharge head or spray pump head and, unlike spray heads, they operate without external pressure below or above the ambient pressure or the pressure exerted by the action of lowering the overall contents of the container, such as by pressing the flexible walls of the container as is well known for the dispensing of liquids

Hypochlorite toilet cleaners, hand dishwashing liquids and similar liquid products.

For practical reasons such as ease of construction and handling, the container preferably does not contain more than two chambers, each containing a partial composition which together form the final composition of the invention. This implies that, for the same reasons, the cleaning compositions of the invention are preferably two-part compositions. The container may have a mixing chamber as described above.

The amounts of the partial compositions constituting the final composition need not necessarily be equal, as long as care is taken that the concentrations of each component in each partial composition are selected such that, when the recommended amounts are mixed, the final composition will have the correct concentrations of each component. The volume of each chamber of the container is adjusted to the amount of the partial composition contained in that chamber, the amount required to produce the total amount of the final composition in the container. The total liquid volume of the final composition to be obtained from the container will be approximately equal to the total volume of the container, excluding the volume of the mixing chamber, if any.

The dispensing system, for example the dispensing or exit holes in the chambers of a container, is arranged such that a single dispensing provides the correct amount of all partial compositions necessary to properly form the final composition, each component of which is present at the desired concentration.

While there is no theoretical limitation on the size and shape of the container, for practical reasons such as ease of handling and dispensing, the container will generally have a total volume of 0.1-2 liters, preferably at least 0.25 liters, but preferably no more than 1 liter. 5l. Also for practical reasons, two compartment containers preferably have chambers of approximately equal volume holding equal amounts of each of the two part compositions.

Suitable containers are described in co-pending British patent applications GB98 15659.9 (unpublished); GB98 15660.7 (published as GB2339757) and GB98 15661.5 (unpublished).

The peroxide 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, e.g. perbenzoic acid, and substituted perbenzoic acids, various aliphatic peroxy acids and diperoxy acids such as peracetic acid, diperoxydodecanedioic acid, N, N-phthaloyl amino-peroxy caproic acid ( PAP), various organic or inorganic persalts such as monoperoxysulphates, perborates, perphosphates, persilicates, etc. Such peroxy bleach compounds can be used in combination with bleach activator compounds to increase the bleaching activity. Many compounds require activating compounds for proper bleaching action.

Preferred peroxide bleaches are hydrogen peroxide, peracetic acid and alkali or alkaline earth metal monoperoxysulfates. Hydrogen peroxide is particularly suitable. The amount of peroxide compound is preferably such 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 peroxide compound has a pH at which the peroxide compound is storage stable. Many peracids and persalts have limited solubility in alkaline solutions and therefore the partial composition containing them will preferably have a pH of at most 8, more preferably at most 7.5, most preferably 7, or less. Hydrogen peroxide is suitably stable at a pH of up to 10, although for prolonged storage preferably the pH should not exceed 9.5, more preferably it should be at most 9.0, most preferably it should be at most 8.0.

Many bleach activators are acrylated (especially acetylated) amines and amides, the best known example of which is tetraacetyl ethylenediamine (TAED). Very well known examples of peroxide / activator combinations are perborate / TAED and percarbonate / TAED.

Useful bleach activator compounds are cationic nitriles such as the N-alkylammoniumacetonitriles described in EP-A-0303520, EP-A-0458396, EP-A-0464880, WO 96/40661, WO 98/23533, DE-19629159 and EP -A-0790244, and cyanopyridinium compounds and pyridine N-oxides are disclosed in EP-A-0806473 and EP-A-0819673. Similar useful cyano activating compounds are disclosed in EP-A-819673 and DE-19609955.

PL 192 953 B1

Particularly useful bleach activators are imines, such as the sulfonimines described in US-A-5041232, US-A-5047163, and imine quats. Quaternary imine compounds are known and many specific examples are given in US-A-5360568, US-A-53360569 and US-A-5478357. Further examples are described in WO 96/34937, WO 97/10323, WO 98/16614 and US-5710116. Suitable sulfonimines have the general formula:

R ¹ R ² C = N-SO ₂ -R ³ wherein R ₁ ¹ is hydrogen or a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl ₂ phenylsulfonyloxy; R is hydrogen or a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl group, or a ketone, carboxyl, carboalkoxy or group

R ¹ C = N-SO ² -R 3; R ³ is a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl 1 2 2 3 or cycloalkyl group, or a nitro, halogen or cyano group; R with R and / or R with R may suitably form a cycloalkyl, heterocyclic or aromatic ring.

Suitable quaternary imine salts have the formula _R ¹ R ² C = N ⁺ R ³ R ⁴ _X ^- wherein R ¹ and R ⁴ are hydrogen, or a substituted or unsubstituted phenyl, aryl, heterocyclic, _2- alkyl or cycloalkyl group; R is hydrogen or a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl group, or a ketone, carboxy or carboalkoxy group;

Preferred quaternary imine salts (imine quats) have a 3,4-dihydroisoquinoline structure:

where R5 and R6 are hydrogen or C1-C30 substituted or unsubstituted phenyl, aryl, heterocyclic ring, alkyl, cycloalkyl or nitro, halogen, cyano, alkoxy, carboxy or carboalkoxy group, and R4 is C1-C30 substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl. R5 is more than one substituent on an aromatic ring. Representative examples of compounds of the general formula above (with one R5 substituent) are given in the table.

Particularly useful are imine quaternary compounds in which R4 is an alkyl group such as methyl or a substituted alkyl group and where R6 is hydrogen or a C1-C5 alkyl or phenyl group. Also very useful are compounds in which R 5 is one or two methoxy groups, such as two methoxy groups at the 6 and 7 positions. Examples of preferred quaternary iminium compounds are the N-methyl-3,4-dihydroisoquinoline salts and the corresponding quaternary salts, such as wherein R6 is methyl or ethyl, respectively. These compounds are particularly preferably used in combination with hydrogen peroxide.

Quaternary imines have only limited stability at high pH values and therefore a partial composition containing these imines should preferably have a pH below 8, more preferably at most 7, most preferably between 2.0 and 6.5. If used, the imine quaternary compounds are generally present in an amount of 0.001-10%, preferably 0.01-5%, most preferably no more than 2%. In general, the molar ratio of the peroxy compound to the quaternary iminium compound ranges from 1500: 1 to 1: 2, more preferably from 150: 1 to 1: 1, more preferably from 60: 1 to 2: 1.

If a bleach activator is used, it may be a component of the same partial composition as the peroxy compound, provided that both of them have sufficient storage stability at a pH that is appropriate for the partial composition given the pH requirements of the final composition. Otherwise, the activator and the peroxy compound are stored separately in different partial compositions. Thus, a partial composition comprising both hydrogen peroxide and the quaternary iminium compound together preferably has a maximum pH of 6.5, more preferably at most 6.

To achieve thorough mixing of the partial compositions when dispensing them, the partial compositions should be thin before mixing, i.e. they should have a viscosity of 20 mPa.s or less, preferably 10 mPa.s or less, more preferably at most 5 mPa.s (Haake ™ R20 Viscometer). , at a temperature of 25 ° C, with a shear rate: 21 sec ^-1 ). Although the viscosities of all the partial compositions prior to mixing may not necessarily be equal, they are preferably not too distant as this may affect the relative amounts of the partial compositions dispensed in one dispensing operation and the mixing thereof. Differences in viscosity can be compensated for by adjusting the dosing means, for example by appropriately differentiating the dimensions of the exit openings from the respective chambers.

PL 192 953 B1

During or immediately after application to the surfaces to be cleaned, the composition is compacted to a suitable density sufficient to adhere to the surface and prevent it from flowing off non-level surfaces before they are properly cleaned. Such thickening is achieved by mixing the components of a multi-component thickening system, the components of which are divided into 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 (measured under the conditions defined above).

A large number of multi-component thickening systems are known in the art. To be suitable for the cleaning compositions of the invention, preferably, the at least one component should be stable in the same partial composition as the peroxy bleach compound. The entire thickening system in the final composition should be sufficiently stable to allow the composition to thicken and remain on the surface for a sufficient time to exhibit its cleaning effect.

Many thickening systems are used in thickened hypochlorite bleach compositions. Such systems often consist of two or more different detergent surfactants, or one or more surfactants in combination with an electrolyte such as an inorganic salt. Many thickening systems contain a tertiary amine oxide, an ethoxylated fatty alcohol or other nonionic surfactant as one component, and an anionic surfactant as other components.

Examples of such thickening systems are described in EP-A-079697, EP-A-110544, EP-137551, EP-A-145084, EP-A-244611, EP-A-635568, WO 95/08611, DE-A -19621048 and the literature cited therein.

Other suitable thickening systems include polymeric substances that thicken in solution in response to an increase in the pH value or electrolyte concentration. Examples are polymers of acrylic acid, known for their thickening properties, such as those sold under the trademark "Acusol".

Examples of various thickening systems preferably comprised in the relative amounts of their components (in% of the total surfactant blend) and their possible separation into partial compositions are given below:

One partial composition Second partial composition Non-ionic center of the area open (60-30) Cationic surface agent open (40-70) Inorganic salt Cationic surface agent open (10-30) Anionic center of the area open (90-70) Inorganic salt Anionic center of the area open (90-70) Cationic surface agent open (10-30) Inorganic salt The center of the area open time amines (85-60) Anionic center of the area open (15-40) Non-ionic center of the area open (60-30) Anionic center of the area open (40-70) Inorganic salt Anionic center of the area open (90-70) Cationic surface agent open (10-30) Inorganic salt Cationic surface agent open (95-85) Anionic center of the area open (5-15) Inorganic salt Polyacrylate latex Measure adjust. pH to alkaline

For certain multi-component thickening systems, all components may be present in one partial composition if at least one component is present at a concentration below that necessary to effect the thickening of the system, and the remainder of the component is present in another partial composition. Thus, when mixing the partial compositions, the concentration of this component in the final composition is increased to the amount required to cause thickening.

PL 192 953 B1

Detergent surfactants often play an important role in thickening systems as described above. Regardless of this, they are also preferably added for hard surface wetting and cleaning properties. Thus, preferably, surfactants are present even when a non-surfactant thickening system is used. If not required for thickening, the total amount of surfactants is preferably between 0.1 and 20%, more preferably between 0.5 and 10%, most preferably at most 7%. If part of the thickening system, the minimum total amount of surfactant is at least 0.5%, preferably at least 1%.

Surfactants can be selected from a wide variety of anionic, nonionic, cationic, amphoteric and zwitterionic surfactants well known to those skilled in the art.

Suitable anionic surfactants are, for example, water-soluble salts, especially alkali metal, alkaline earth metal and ammonium salts, esters of organic sulfates and sulfonic acids having a C8-C22 alkyl radical or a C10-C22 alkaryl radical in the molecule. Examples of such anionic surfactants are alcohol sulfates, especially those derived from fatty alcohols derived from tallow and coconut oil glycerides, alkyl benzene sulfonates such as with C9-C15 carbon atoms in the alkyl group. Examples of such anionic detergents are alcohol sulfates with alkyl groups attached to the benzene ring; secondary alkanesulfonates, sodium alkyl glyceryl ether sulfates, especially fatty alcohol ethers derived from tallow and coconut oil; monoglyceride sulfates of sodium fatty acids, especially coconut fatty acids; salts of 1-6 EO of ethoxylated fatty alcohol sulfates, salts of 1-8 EO of ethoxylated alkylphenol sulfates in which the alkyl radicals contain 4-14 carbon atoms; reaction products of esterified fatty acids with isetonic acid and neutralized with sodium hydroxide.

Preferred water-soluble synthetic anionic surfactants are alkyl benzene sulfonates, olefin sulfonates, alkyl sulfates and fatty acid monoglyceride sulfates. On the other hand, fatty acid soaps are not very suitable for use in the cleaning compositions of the present invention.

A special class of anionic surfactants that can be used in the cleaning compositions of the invention are hydrotropes, known in the art especially for their thickening or liquid structuring properties. Well known examples of such compounds are the alkali metal salts of toluene, xylene and cumene sulfenic acids.

Suitable nonionic surfactants can be broadly described as compounds produced by the condensation of alkylene oxide groups, which are hydrophilic in nature, with organic hydrophobic compounds which may be aliphatic or alkyl aromatic. The length of the hydrophilic or polyoxyalkylene radical attached to any particular hydrophobic group can be readily adjusted to obtain a water-soluble or water-dispersible compound having the desired balance between the hydrophobic and hydrophilic elements.

Further examples include the condensates of straight or branched aliphatic alcohols having 8-22 carbon atoms with ethylene oxide, such as coconut oil fatty alcohol / ethylene oxide condensates having from 2 to 15 moles of ethylene oxide per mole of coconut alcohol; alkylphenol condensates whose alkyl groups contain 6-16 carbon atoms with 2 to 25 moles of ethylene oxide per mole of alkylphenol; condensates of the reaction products of ethylene diamine and propylene oxide with ethylene oxide, condensates containing from 40 to 80% by weight of ethyleneoxy groups with a molecular weight of 5000 to 11000. Other examples are: tertiary amine oxides of the general formula RRRNO, where one example R is an alkyl group C8- C22 (preferably C8-C18) and each of the remaining R is a C1-C5 (preferably C1-C3) alkyl or hydroxyalkyl group, for example dimethyldodecylamine oxide; quaternary phosphine oxides of structure RRRPO where one R is a C8-C22 (preferably C8-C18) alkyl or hydroxyalkyl group; for example dimethyldodecylphosphine oxide; dialkyl sulfoxides of structure RRSO where one R is a C10-C18 alkyl group and the other is a methyl or ethyl group, for example methyltetradecyl sulfoxide; fatty acid alkoxyamide; alkylene oxide condensates with fatty acid alkylamides and alkyl mercaptans. Ethoxylated aliphatic alcohols are particularly preferred. Amine oxides are also suitable because they mix very well with inorganic electrolytes. Suitable amphoteric surfactants are derived from aliphatic secondary and tertiary amines containing a C8-C18 alkyl group and an aliphatic substituted group

By an anionic water-solubilizing group, for example sodium 3-dodecylaminopropionate, sodium 3-dodecylaminopronane sulfonate and sodium N-2-hydroxydodecyl N-methyl taurate.

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, didecyldimethylammonium bromide or chloride. Many quaternary salts have antimicrobial properties and their use in the cleaning compositions of the invention results in products with disinfectant properties. They are used in the cleaning compositions of the invention in an amount of 0-10%, preferably 0.1-8%, more preferably 0.5-6%.

Suitable zwitterionic surfactants are derivatives of aliphatic quaternary ammonium, sulfonium and phosphonium compounds having an aliphatic C6-C18 group and an aliphatic group substituted with an anionic water-solubilizing group, e.g. 3- (N, N-dimethyl-N-hexadecylammonium) propane- Betaine-1-sulfonate, Betaine 3- (dodecylmethylsulfonio) propane-1-sulfonate and Betaine 3- (cetylmethylphosphonio) ethanesulfonate.

Further examples of suitable surfactants are given in the well-known book publication "Surface Active Agents Vol. L Schwartz and Perry and" Surface Active Agents and Detergents Vol. II Schwartz, Perry and Berch.

The storage-stable surfactants in combination with the peroxy compound may be combined with the peroxy compound in the same partial composition. Surfactants without adequate stability should form part of the other partial composition or other partial compositions. Thus, the quaternary ammonium halides are preferably not combined with the peroxy compound in the same partial composition because of the possible degradation of the peroxy compound by the halogen ion. This is especially true for bromides and iodides.

The partial composition containing the peroxy bleach compound preferably also includes a sequestering agent to bind metal ions, especially transition metal ions, which otherwise destabilize the peroxy compound. Suitable sequestering agents are, for example, ethynediamine tetraacetate, amino polyphosphates (such as DEQUEST ™). A wide variety of polyhydric organic and inorganic acids and salts can also be optionally included. Preferred sequestering agents are selected from dipicolinic acid, ethylenediaminetetraacetic acid (EDTA) and its salts, hydroxyethylidene diphosphinic acid (Dequest 2010), ethylenediaminetetra (methylene phosphinic acid) (Dequest 2040), diethylenetriamino penta (methylene phosphinic acid 2060) (Dequest 2060). Such sequestering agents are generally used in an amount of 0.01-5%, preferably 0.05-2%.

Electrolytes, especially inorganic salts, are part of many thickening systems. Suitable salts are alkali metal carbonates, sulfates and halides. The halides, especially bromides and iodides, are preferably kept separate from the peroxy compounds, i.e. in various partial compositions. The electrolytes are used in amounts of 0-20%, preferably 0-15%, more preferably 0-10%.

In addition to the aforementioned sequestering agents particularly suitable for binding transition metal ions, the cleaning compositions of the invention may also contain a sequestering agent suitable for binding Ca ions. Such sequestering agent may be included in any partial composition. Suitable sequestering agents for this purpose are well known in the art and include compounds such as: alkali metal tripolyphosphate, pyrophosphate and orthophosphate, sodium nitrilotriacetic acid, sodium methylglycine diacetic acid, alkali metal citrate, carboxymethyl malonate, methylglycinimethylacetic acid, methylglycin diacetic acid. , tartrate, mono- and disuccinate, and oxodisuccinate.

Since many peroxy compounds are storage stable at pH values lower than their maximum bleach electrolyte, the partial peroxy bleach free composition preferably contains sufficient alkali to increase the pH of the final composition from that 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 are preferably all aqueous liquids as well, although some or all may additionally contain an organic solvent. These organic solvents must be sufficiently stable with the peroxygen bleach not to interfere with the cleaning process with the final composition.

Also, not all thickening systems will thicken sufficiently in the presence of an organic solvent, and therefore appropriate thickening systems must be selected. For most cleaning purposes, the presence of an organic solvent will not be required.

Other minor ingredients may be present in the cleaning compositions of the invention to improve their cleaning or disinfecting properties, such as microbicidal active compounds other than the aforementioned quaternary amine salts, or compounds for improving the appearance of the composition. Examples of the latter are perfumes and dyes. Certain perfume ingredients, such as certain essential oils, are known to have antimicrobial properties and can therefore provide dual activity.

For the purposes of the invention, an ingredient or a partial composition is considered storage stable if it retains at least 50% of its original activity or activities after 10 days of storage at 20 ° C. Depending on the ingredients present in the partial compositions, the activity may include: surfactant activity, thickening activity, disinfecting activity, peroxygen compound activity, bleach activator activity, etc. For better storage stability, the activity or activities should be at least 50% after 30 days of storage , more preferably 60 days storage at 20 ° C.

All percentages quoted are by weight of the final composition, unless otherwise indicated.

Aqueous cleaning compositions were prepared each consisting of equal amounts of partial compositions a) and b). All compositions contained N-methyl-3,4-dihydroisoquinoline tosylate as a quaternary imine compound. All were stored in a two-compartment container consisting of two separate "half-containers held together by an adhesive enveloping sleeve and a single piece dispensing nozzle arrangement. The percentages of ingredients in the examples are based on the partial weight of the composition they constitute, the balance being water. Thus, the percentage in the final composition is half of the stated values.
