Description

DETAILED DESCRIPTION OF THE INVENTION

FIELD OF THE INVENTION The present invention comprises at least two partial compositions which are housed separately from each other in a single container comprising at least two chambers and are mixed in use, one of which is a partial composition. Relates to a liquid detergent composition comprising a peroxygen bleach compound.

The compositions are for cleaning and disinfecting household surfaces and are particularly preferably used for non-level surfaces (ie sloped or vertical surfaces) such as those found in bathrooms and toilets.

BACKGROUND OF THE INVENTION [0003] Existing compositions for cleaning and disinfecting non-level surfaces consist of an alkali metal hypochlorite solution that is poured, sprayed or sprayed onto such surfaces. Such a solution is thickened so that the solution does not run off the surface too quickly. Such solutions, especially for toilet cleaning, are often marketed packaged in spouted containers and the solution is squeezed out of the spout of the container to a surface. Such spouts are sometimes mounted on the container so that the jet of liquid created by the squeezing action can easily reach every corner or underside of the edge, which otherwise cannot be easily reached.

[0004] One problem with such compositions is that hypochlorite has an unpleasant odor and releases toxic amounts of chlorine gas when mistakenly mixed with acidic substances. is there. Peroxides are known in particular as additional bleaching agents. However, peroxides are often storage-unstable in formulation form or cannot exhibit good bleaching performance at storage-stable pH.

[0005] Toothpaste and peroxide-based hair bleach compositions are formulated as weakly acidic peroxide solutions or gels, and are intended to be mixed with another weakly alkaline solution or paste immediately before use. This product form, as is known, takes advantage of the fact that peroxide is more stable to decomposition under acidic conditions, but is more effective as a bleach under alkaline conditions.

[0006] Another two-part composition of peroxide base is described in JP-A-60 / 038497 (LION
BRANDS). The patent discloses: (a) 0.5 to 50% by weight of hydrogen peroxide; (b) an alkali having an alkalinity of a sodium hydroxide base of 0.1 to 50%; (c) (a) or (b) ), And (d) a terpene alcohol / cyclic terpene alcohol contained in (a) or (b).

[0007] The compositions (a) and (b) containing the surfactant and the terpene are supplied to the toilet sequentially or simultaneously and enter the drain. In the drain, the composition creates a foam mass that performs the cleaning action and, if necessary, clears the drain.

Another form of simultaneous delivery of two components is also known. For example, US-A-3,760
, 986 disclose a dispense bottle that discharges two separate fluids to a common point. Such a bottle has an opening formed at the top, and a partition forming two compartments serving as two fluid tanks extends inside the bottle. The disclosed apparatus further includes pump means for simultaneously pumping fluid from each of the compartments via a separate pumping tube and discharging to a common point. The device can store the alkaline and acidic materials separately and spray from a single device to a common point.

WO 95/16023 discloses a container comprising two chambers or tanks, one containing an acidic or neutral liquid composition consisting of a peroxide compound and the other containing an alkaline liquid composition. ing. The container is equipped with a spray system that sprays the mixture of the two components as a single spray or sprays the spray of each of the two components simultaneously on the same point on the surface and mixes the components at the surface. The product is delivered as fine droplets, which coalesce at the surface and the two compositions mix easily and completely. The composition may itself be thickened, or it may contain a thickening system that produces a thickening upon mixing. Thickening systems are particularly suitable for improving spray properties and preventing respiratory irritation caused by extremely fine droplets. In an embodiment, both components are thickened before spraying.

WO 97/31087 has two chambers or tanks, one containing a liquid composition consisting of peroxygen bleach and the other containing a liquid composition consisting of a builder or chelating agent. Discloses a container containing a pH adjuster that at the time of mixing the liquids brings the pH of the mixture to a value such that the peroxygen bleach is effectively cleaned and stable. Preferably the peroxygen bleach is a peracid or persalt, and the pH is between 9.0 and 1
1.5. The two liquid compositions are preferably mixed when delivered to a surface by a spray system. A similar system is described in WO 98/23533, in which a combination of hydrogen peroxide and a tertiary N-alkylammonium acetonitrile salt from one chamber and an alkaline solution from the other chamber are sprayed onto a surface. Sent out.

[0011] These prior art two-component peroxide cleaning systems suffer from the disadvantage that the spray system can only deliver a limited amount of product to the surface, and to locations that are usually inaccessible because the container must be held vertically. Has the disadvantage of not reaching. Therefore, these systems are not well suited for toilet cleaning purposes. Further, spray systems such as trigger spray heads and pump sprays, especially those suitable for multi-compartment containers, are relatively expensive.

SUMMARY OF THE INVENTION Accordingly, one object of the present invention is to provide a liquid for cleaning hard surfaces which contains peroxygen bleach, is storage-stable, and exhibits excellent cleaning and disinfecting effects when applied to a surface. It is to provide a composition.

Another object of the present invention is to provide a viscous material that can be easily applied to a surface using a non-spray dispense system, is sufficiently thickened on the surface, and is suitable for cleaning non-level surfaces, especially toilets. It is to provide a liquid detergent composition for hard surface cleaning which gains a degree.

Yet another object of the present invention is to provide a liquid detergent composition for hard surface cleaning wherein components that are not storage stable in the presence of each other are kept separate from each other until the point at which the composition discharges to the surface. It is to be.

Accordingly, the present invention provides for at least two chambers or tanks or compartments (hereinafter referred to as “chambers”) and at least two chambers housed separately from each other in a single container having a non-spray dispense system. A liquid detergent composition comprising at least one liquid sub-composition, wherein at least one sub-composition comprises a peroxygen bleach compound, wherein the detergent composition comprises a multi-component thickening system; Is divided into at least two partial compositions, and the combination of the components of the thickening system thickens the final composition and causes it to adhere to the non-horizontal surface when the partial compositions delivered to the surface to be cleaned mix. Such a detergent composition is provided. Each partial composition has a pH such that the components of the partial composition are storage stable, but the final composition after mixing of the partial compositions has a pH suitable for washing.

[0016] The present invention is further directed to a thickened liquid detergent composition obtained by mixing two or more partial compositions delivered from a non-spray dispense system, wherein at least one of the partial compositions is a peroxygen bleach. At least two partial compositions, each compound comprising one or more (but not all) components of a multi-component thickening system;
The mixing of the partial compositions produces a thickening effect, each of the partial compositions has a pH such that the components of the partial composition are storage stable, and the final composition after mixing of the partial compositions is effective. The present invention provides a thickened liquid detergent composition having a pH suitable for cleansing.

The present invention also includes two or more chambers, each chamber having an outlet for discharging the contents of each chamber, which outlets together form part of a non-spray dispense system. Providing a container forming the same. The container contains a liquid portion composition as described above.

DETAILED DESCRIPTION The term "partial composition" is defined herein as a component of the final composition or a mixture of two or more (but not all) components of the final composition. Such components or mixtures are contained in separate chambers of a container containing the entire composition.
Two or more partial compositions together make up the final detergent composition of the present invention.

A container suitable for containing the detergent composition of the present invention has at least as many independent chambers as the number of partial compositions that make up the entire composition. Such a container may have one outer wall surrounding all chambers separated from each other by a partition wall inside the container, or may be composed of as many independent containers as chambers;
These containers may be held together so as to be held and operated as one container by some external means, such as a wall connecting member or an adhesive sleeve surrounding the wall. The dispensing system provided in each chamber has an outlet for discharging the partial composition. All of these outlets may be guided to one independent mixing chamber and mixed in the mixing chamber just before the discharge volume of the partial composition is applied to the surface from the outlet of the mixing chamber. Alternatively, all outlets may be guided out of the container and simultaneously applied to the same area of the surface so that the entire volume of the partial composition is mixed during or immediately prior to application. For this purpose, all partial compositions are poured or sprayed on the same area of the surface in one operation,
In general, the outlets must be located very close to each other. The outlet is equipped with a nozzle system designed to further improve the mixing of the constituents when leaving the vessel. Dispensing systems as described above and similar systems known in the art are encompassed by the term "non-spray dispensing system". A universal feature of these systems is that, unlike such spray heads, without the so-called "trigger spray head or pump spray head", they operate without the application of external pressure above ambient pressure, or liquid hypochlorite. By applying pressure, for example, by compressing the flexible wall of the container to reduce the total internal volume of the container, as in known dispensing containers for acid salt toilet cleaners, dishwashing detergents and similar liquid products. is there.

For practical reasons, such as to facilitate the preparation and manipulation of the container, the container may comprise three or more chambers, each containing a partial composition that together make up the final composition of the present invention. Preferably it does not. For the same reason, the partial composition of the present invention is preferably composed of two partial compositions. Further, the container may have a mixing chamber as briefly described above.

If the concentration of each component in each partial composition is taken into account such that each component is present at the correct concentration in the final composition by mixing the predetermined amount of the partial composition, the components that make up the final composition The amounts of the compositions need not all be equal. The volume of each chamber of the container corresponds to the amount of partial composition that needs to be contained in the chamber to make up the total amount of the final composition in the container. The total liquid volume of the final composition obtained from the container is generally approximately equal to the total volume of the container and, if a mixing chamber is present, approximately equal to the total volume of the container minus the volume of the mixing chamber.

The dimensions of the dispensing system, for example the dimensions of the outlet or outlet of the chamber of the container, are such that all partial compositions are dispensed in the exact required quantity in a single dispensing operation and each component is present in the desired concentration. It is set to make up the final composition properly.

Although there are no theoretical restrictions on the size and shape of the container, the total volume of the container is generally 0.1 to 2 liters, preferably for practical reasons such as ease of operation and discharge. It is at least 0.25 liter and preferably at most 1.5 liter. Also for practical reasons, the two-chamber container preferably has approximately equal volumes of chambers, and preferably each of the two sub-compositions is contained in approximately equal volumes.

Suitable containers are described in co-pending UK Patent Application No. 98 15659.9,98
15660.7 and 98 15661.5.

The peroxygen bleach compound can be any peroxide or peroxide generating system known in the art. Known examples are hydrogen peroxide, various organic or inorganic peracids, such as perbenzoic acid and substituted perbenzoic acid, various aliphatic peroxy acids and diperoxy acids, such as peracetic acid, diperoxy-dodecane diacid, N, N-phthaloylamino-peroxycaproic acid (PAF), various organic or inorganic persalts such as monoperoxosulphate, perborate, perphosphate, persilicate, etc. . Such peroxygen bleach compounds may be used in combination with bleach activator compounds that enhance their bleaching activity. Many of these compounds require an activating compound to obtain proper bleaching action.

Preferred peroxygen bleach compounds are hydrogen peroxide, peracetic acid, and alkali or alkaline earth metal monoperoxosulfates. Hydrogen peroxide is particularly preferred. The amount of the peroxygen compound is preferably 0,1 in the final composition.
05-10%, more preferably 0.1-5%, most preferably at least 0.5
% Active oxygen will be selected.

[0027] The partial composition containing the peroxygen compound has a pH such that the peroxygen compound is storage stable. Many peracids and persalts have a limited stability in alkaline solutions, and therefore the partial compositions containing them are preferably less than 8, more preferably less than 7.5, most preferably less than 7 Will have a pH of. Hydrogen peroxide can be said to be stable up to pH 10, but in order to ensure long-term stability, the pH is preferably 9.5 or less, more preferably 9.0 or less, and most preferably 8.0 or less. No.

Many bleach activators are found in acylated (especially acetylated) amines and amides. Tetraacetyl-ethylenediamine (TAED) is probably the best known example. Very well known examples of peroxide / activator combinations are perborate / TAED and percarbonate / TAED.

Useful bleach-activating compounds are cationic nitriles, such as EP-A-0303
520, EP-A-0458396, EP-A-0464880, WO96 / 4
0661, WO 98/23533, DE-19629159 and EP-A-07
90-244 N-alkyl-ammonium acetonitrile and E
Cyanopyridinium and pyridine-N-oxide compounds disclosed in PA-0806473 and EP-A-0196733. Similarly useful cyano activating compounds are disclosed in EP-A-0819673 and DE-19609955.

Particularly useful bleach activating compounds are imines, for example US-A-5,041,23
2, sulfonimines and imine quats as described in US-A-5,047,163. The quaternary imine salt is US-A-5,3
60,568, US-A-5,360,569 and US-A-5,478,35
7, and many specific embodiments are shown. Other examples are WO96 /
34937, WO97 / 10323, WO98 / 16614 and US-5,71
0,116.

Suitable sulfonymines have the following general structure: R¹R²C = N-SO₂-R³  have.

Wherein R ¹ may be hydrogen or a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl group; R ² may be hydrogen or substituted or unsubstituted phenyl, aryl, A heterocyclic, alkyl or cycloalkyl group or a keto, carboxyl, carboalkoxy or R ¹ C = N—SO ₂ —R ³ group; R ³ can be substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or It may be a cycloalkyl group or a nitro, halo or cyano group; R ¹ and R ² and / or R ² and R ³ may each form a cycloalkyl, heterocyclic or aromatic ring system.

Suitable quaternary imine salts have the general structure: R¹R²C = N⁺R³R⁴X⁻  have.

Wherein R ¹ and R ⁴ may be hydrogen or a substituted or unsubstituted phenyl, aryl, heterocycle, alkyl or cycloalkyl group; R ² is hydrogen or a substituted or unsubstituted phenyl R ³ may be a substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl or cycloalkyl group, or a nitro, halo group, an aryl, heterocyclic, alkyl or cycloalkyl group, or a keto, carboxyl or carboalkoxy group. Or a cyano group; R ¹ and R ² and / or R ² and R ³ may each form a cycloalkyl, heterocyclic or aromatic ring system, and X ⁻ represents the presence of a peroxide compound. It is a stable counter ion below.

Preferred quaternary imine quats have the following 3,4-dihydro-isoquinolinium structure:

[0036]

Embedded image have.

In the formula, R5 and R6 are hydrogen, or a C1-C30 substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl, cycloalkyl group, or nitro, halo, cyano, alkoxy, carboxyl and It may be a carboalkoxy group and R4 is C1
It may be -C30 substituted or unsubstituted phenyl, aryl, heterocyclic, alkyl and cycloalkyl groups. R5 may represent two or more substituents on the aromatic ring. Examples of compounds of this general structure (having one R5) are shown in the table below.

[0038]

[Table 1]

Particularly useful are quaternary imine salts wherein R4 is an alkyl group such as methyl or a substituted alkyl group and R6 is hydrogen or a C1-C5 alkyl or phenyl group. Compounds in which R5 represents one or two methoxy groups, for example, two methoxy groups at the 6-position and the 7-position, are also very useful. Examples of preferred quaternary imine salts are N-methyl-3,4-dihydroisoquinolinium salts and the corresponding quats where R6 is methyl or ethyl, respectively. These are particularly advantageous when used in combination with hydrogen peroxide.

The storage stability of the quaternary imine salts at high pH is very limited and therefore the partial compositions containing these imines are preferably 8 or less, more preferably 7 or less, most preferably 2.0-6. Must have a pH of 0.5. When used, the quaternary imine salt is generally present in an amount of 0.001 to 10%, preferably 0.01 to 5%, and most preferably 2% or less. The molar ratio of the peroxygen compound to the quaternary imine salt will generally range from 1500: 1 to 1: 2, preferably 150: 1 to 1: 1, more preferably 60: 1 to 2: 1.

When a bleach activator compound is used, the bleach activator compound may constitute the same component of the partial composition as the peroxygen compound, but the appropriateness of the partial composition set in consideration of the pH requirements of the final composition At pH the condition that both compounds have sufficient storage stability must be met. Otherwise, the activator and the peroxygen compound are housed separately in different partial compositions. Therefore,
Partial compositions containing both hydrogen peroxide and a quaternary imine salt preferably have a pH of at most 6.5, preferably 6 or less.

In order to achieve a thorough mixing of the partial compositions on ejection, all the partial compositions must not be viscous before mixing, ie, 20 mPa.s. s or less, preferably 10 mPa.s. s
Or less, more preferably 5 mPa. s or less (Haake ^™ R20 viscometer, 25
° C, shear rate: 21 sec ^-1 ). The viscosities of all the partial compositions before mixing do not necessarily have to be equal, but it is preferable that the viscosities are not far apart. This is because the viscosity of the partial composition affects the relative amounts of the partial compositions to be discharged in one discharging operation and their mixing. The difference in viscosity may be compensated for by adjusting the dispensing means, for example by sizing the outlet of the corresponding chamber differently in response to the difference in viscosity.

During or immediately after application to a surface, the detergent composition thickens sufficiently to adhere to the surface and not run off an uneven surface before adequate cleaning is obtained. This thickening results from the mixing of the components of the multi-component thickening system divided into at least two partial compositions. The viscosity of the final composition after ejection is preferably at least 5
0 mPa. s, more preferably at least 100 mPa.s. s. On the other hand, the viscosity is preferably 1000 mPa.s. s or less (measurement conditions: see above).

A number of multi-component thickening systems are known in the art. In order for these thickening systems to be suitably used in the detergent compositions of the present invention, preferably one component must be storage-stable in the same partial composition as the peroxygen bleach compound. The entire thickening system must be sufficiently stable in the final composition so that the composition can thicken and remain on the surface for an extended period of time to sufficiently exert its cleaning action.

Many thickening systems have been used in thickened hypochlorite bleach compositions. Such systems often consist of two or more different detergent surfactants,
Alternatively, it is composed of one or more such surfactants in combination with an electrolyte such as an inorganic salt. Many thickening systems contain tertiary amine oxides, ethoxylated fatty alcohols or other nonionic surfactants as one of their components, and anionic surfactants as another component.

Examples of such thickening systems are described in EP-A-079697, EP-A-110544.
, EP-A-137551, EP-A-145084, EP-A-244611

Another suitable thickening system is a polymeric substance that dissolves and thickens in response to increasing pH or increasing electrolyte concentration. Examples are known acrylic acid polymers with thickening properties, such as those sold under the trademark "Acusol".

Examples of various thickening systems, preferred ranges of the relative amounts of their components (expressed as a percentage of the total surfactant mix) and the possibility of splitting between the partial compositions are given below:

[0049]One part composition The other partial composition  Nonionic surfactant (60-30) Inorganic salt Cationic surfactant (40-70) Cationic surfactant (10-30) Anionic surfactant (90-70) Inorganic salt Anionic surfactant (90-70) Cationic surfactant (10-30) Inorganic salt Amine oxide surfactant (85- Anionic surfactant (15-40) 60) Nonionic surfactant (60-30) Inorganic salt Anionic surfactant (40-70) Anionic surfactant (90-70) Inorganic salt Cationic surfactant (10-30) Cationic surfactant (95-85) Anionic surfactant (5 15) Inorganic salt Polyacrylate latex Alkaline pH adjuster

In certain multi-component thickening systems, at least one of the components is present in one of the partial compositions at a concentration lower than that required to cause thickening of the system, with the remainder of this component remaining If present in the other sub-composition, all components may be present in one sub-composition. In this case, upon mixing of the partial compositions, the concentration of the components in the final composition increases to the level required to cause thickening.

Detergent surfactants often play an important role in thickening systems as described above. Apart from this role, it is preferable to add a detergent for cleaning from the viewpoint of wettability and detergency on hard surfaces. Therefore, it is preferable that a surfactant is present even when a thickening system not based on a surfactant is used. If not required for thickening, the total surfactant content is preferably 0.1-20%, more preferably 0.5-10%, most preferably 7% or less. If part of a thickening system, the minimum of the total amount of surfactant will be at least 0.5%, preferably at least 1%.

The surfactant may be selected from a wide range of anionic, nonionic, cationic, amphoteric or zwitterionic surfactants known in the art.

Suitable anionic surfactants are, for example, water-soluble salts of organic sulphates and sulphonic acids having C8-C22 alkyl radicals or C10-C22 alkaryl radicals in the molecular structure, in particular alkali metal salts, Alkaline earth metal salts and ammonium salts. Examples of such anionic surfactants are alcohol sulfates, such as those obtained from fatty alcohols, especially derived from glycerides of tallow or coconut oil; alkylbenzenesulfonates having C9-C15. Examples of such anionic surfactants are alcohol sulfate alkyl groups attached to the benzene ring; secondary alkane sulfonates; sodium alkyl glyceryl ether sulfates such as ethers of fatty alcohols especially derived from glycerides of tallow and coconut oil. Sodium fatty acid monoglyceride sulfate, especially as obtained from coconut fatty acids; salts of 1-6EO ethoxylated fatty alcohol sulfates; salts of 1-8EO ethoxylated alkyl phenol sulfates whose alkyl group contains 4 to 14 C-atoms; It is a reaction product of a fatty acid esterified with isethionic acid and neutralized with sodium hydroxide.

Preferred water-soluble synthetic anionic surfactants are alkyl benzene sulfonates, olefin sulfonates, alkyl sulfates and higher fatty acid monoglyceride sulfates. On the other hand, fatty acid soaps are not considered to be very suitably used in the detergent compositions of the present invention.

A special class of anionic surfactants that can be used in the detergent compositions of the present invention are:
In particular, hydrotropes are known in the art for their thickening or liquid structuring capabilities. Known examples of such compounds are the alkali metal salts of toluene, xylene and cumene sulfonic acid.

Suitable nonionic surfactants are widely described as compounds prepared by the condensation of an alkylene oxide group that is hydrophilic with an organic hydrophobic compound that is aliphatic or alkylaromatic. The length of the hydrophilic or polyoxyalkylene radical attached to any particular hydrophobic group is such that the hydrophilic and hydrophobic elements yield a water-soluble or water-dispersible compound having the desired balance. Easy to adjust.

Particular examples are condensates of linear or branched aliphatic alcohols having 8 to 22 C-atoms with ethylene oxide, for example from 2 to 15 mol of ethylene oxide per mol of coconut alcohol Coconut oil fatty alcohol / ethylene oxide condensate; condensate of alkylphenol having 6 to 16 C-atoms in the alkyl group with 2 to 25 moles of ethylene oxide per mole of alkylphenol; reaction product of ethylenediamine and propylene oxide with ethylene oxide And a condensate. The last condensate contains 40 to 80% by weight of ethyleneoxy groups and has a molecular weight of 5,000 to 11,000. Another example is: general structure RRRN
O wherein one R is a C8-C22 (preferably C8-C18) alkyl group and each of the remaining R is a C1-C5 (preferably C1-C3) alkyl or hydroxyalkyl group Tertiary amine oxides, such as dimethyldodecylamine oxide; structure RRRPO, where one R is C8-C22 (preferably C
8 to C18) alkyl groups, and each of the remaining Rs is a C1 to C5 (preferably C1 to C5)
Tertiary phosphine oxide such as dimethyl dodecyl phosphine oxide; wherein R is a C10-C18 alkyl group and the other R is methyl or ethyl. Dialkyl sulfoxides such as methyltetradecyl sulfoxide; fatty acid alkylolamide; alkylene oxide condensates of fatty acid alkylolamide and alkyl mercaptan. Ethoxylated fatty alcohols are particularly preferred. Amine oxide is also very suitable because it can be easily blended with an inorganic electrolyte. Suitable amphoteric surfactants are derivatives of aliphatic secondary and tertiary amines containing C8-C18 alkyl groups and aliphatic groups substituted with anionic water-soluble groups, such as sodium 3-dodecylamino-propionate. , Sodium 3-dodecylaminopropanesulfonate and sodium N-2-hydroxydodecyl-N-methyltaurate.

Suitable cationic surfactants are quaternary ammonium salts having at least one C8-C22 hydrocarbon group, for example dodecyl-trimethylammonium bromide or chloride, cetyltrimethylammonium bromide or chloride, didecyl-dimethyl- Ammonium bromide or chloride. Many quaternary ammonium salts have antimicrobial properties, and when used in the detergent compositions of the present invention, products having a disinfecting effect are obtained. These are used in the detergent composition of the present invention in an amount of 0 to 10%, preferably 0.1 to 8%, more preferably 0.5 to 6%.

Suitable amphoteric surfactants are derivatives of aliphatic quaternary ammonium, sulfonium and phosphonium compounds having a C8-C18 aliphatic group and an aliphatic group substituted by an anionic water-soluble group, such as , 3- (N, N-dimethyl-N-hexadecylammonium) propane-1-sulfonate betaine, 3- (dodecyl-
Methyl-sulfonium) -propane-1-sulfonate betaine and 3- (cetylmethyl-phosphonium) -ethane-sulfonate betaine.

Another example of a suitable surfactant is described in the known literature “Surface Active.

wartz, Perry and Berch.

Surfactants that are storage stable in combination with the peroxygen compound can be combined with the peroxygen compound in the same partial composition. Compounds that do not have this stability are components of one or more of the other partial compositions. Therefore,
Preferably, the quaternary ammonium halide is not combined in the same partial composition as the peroxygen compound. The reason is that the peroxygen compound may be decomposed by halogen ions. In particular, bromine and chlorine easily cause this problem.

[0062] The partial composition containing the peroxygen bleach compound may also include a metal ion,
In particular, it preferably contains a sequestering agent that binds to a transition metal ion. In the absence of a sequestering agent, peroxygen compounds tend to be unstable. Suitable sequestering agents are, for example, ethylenediaminetetraacetic acid, amino-polyphosphonates (for example the DEQUEST ^™ series). Various polyhydric organic and inorganic acids and salts may optionally be used. Preferred sequestering agents are dipicolinic acid, ethylenediaminetetraacetic acid (EDTA) and its salts, hydroxyethylidene diphosphonic acid (Dequest 2010), ethylenediaminetetra (methylene-phosphonic acid) (Dequest 2040), diethylene-triaminepenta (methylene- Phosphonic acid) (Dequest 2060). Such sequestering agents are generally used in an amount of 0.01 to 5%, preferably 0.05 to 2%.

Electrolytes, especially inorganic salts, are components of many thickening systems. Suitable salts are the alkali metal carbonates, sulfates and halides. Preferably, halides, especially bromides and iodides, have been separated from the peroxygen compound. That is, it is preferably present in different partial compositions. The electrolyte is 0-20%, preferably 0-1
It is used in an amount of 5%, more preferably 0-10%.

In addition to the sequestering agents that are particularly suitable for binding transition metal ions as described above, the detergent compositions of the present invention also contain suitable sequestering agents for binding Ca ions. Would be effective. Such sequestering agents may be included in any of the partial compositions. Suitable sequestering agents for this are known in the art and include alkali metal tripolyphosphates, pyrophosphates and ortho-phosphates, sodium nitrilotriacetic acid, sodium methylglycine-diacetate, alkali metal citrate, carboxymethyl malonate. , Methyl glycine diacetate, carboxymethyl oxysuccinate, tartrate, mono- and di-succinates and oxydisuccinates.

Since many peroxygen compounds are storage stable at a pH lower than the pH at which they exert their maximum bleaching effect, the partial composition containing no peroxygen compound will reduce the pH of the final composition to storage stability. Preferably, it contains enough alkali to raise it from the required level to the level required for effective bleaching action. The pH of the final composition should preferably be above 9.0, more preferably at least 9.5, more preferably at least 10.5, most preferably at least 11.0. Particularly preferred alkaline materials are the hydroxides and carbonates of the alkali metals.

The final detergent composition is an aqueous liquid, and the partial compositions are also preferably all aqueous liquids. However, some or all of the partial compositions may further contain an organic solvent. Such organic solvents must be sufficiently stable when co-existing with peroxygen bleach so as not to interfere with the washing process of the final composition. In addition, in the presence of an organic solvent, not all thickening systems can necessarily achieve sufficient thickening, so it is necessary to select an appropriate thickening system. For most cleaning purposes, the presence of an organic solvent will not be necessary.

To improve the detergency or disinfection of compositions such as antimicrobial active compounds other than the quaternary ammonium salts already mentioned above, or to make the compositions more attractive to consumers, Other minor components may be present in the inventive detergent compositions. Examples of the latter are perfumes and dyes. Some perfume ingredients, such as certain essential oils, are known in the art to have antimicrobial properties and thus may provide a dual activity.

For the purposes of the present invention, a storage ingredient is considered stable if it retains at least 50% of one or more initial activities after storage at 20 ° C. for 10 days. Depending on the components of the partial composition, such activities include surface activity, thickening activity, disinfecting activity, active oxygen content, bleach activating activity, and the like. For preferred storage stability, one or more activities should be at least 50% after storage at 20 ° C. for 30 days, more preferably after storage for 60 days.

All percentages expressed herein are weight percentages of the final composition, unless otherwise specified.
