Description

FIELD OF THE INVENTION

The present invention relates to stable, convenient to use, products for washing with a standard dose of detergent, which are able to provide good cleaning, including bleaching, and also be safe for fabrics.

State of the art

Today, the consumer wants to have a washing product with increased cleaning efficiency and at the same time convenient to use and with reduced energy requirements - for example, by washing at low temperatures.

Sources of peroxygens, such as hydrogen peroxide, with or without bleaching activators, are used to remove stains and improve the whiteness of light colored fabrics during washing. However, such agents tend to have lower efficacy at lower temperatures. Means for achieving better whitening performance at low temperature are based on the use of organic whitening catalysts in combination with activated peroxygen sources. In order to maximize the whitening efficiency, it is desirable to quickly and evenly distribute the whitening catalyst, preferably a source of activated peroxygen, in the wash. Additionally, by quickly and uniformly distributing the bleaching catalyst and the source of activated peroxygen, tissue damage due to bleaching stains is avoided. Means for achieving this goal include incorporating a whitening system containing organic whitening catalysts and activated peroxygen sources into the liquid laundry detergent composition. However, it remains difficult to prevent the source of activated peroxygen from reacting with an organic bleaching catalyst or other sensitive laundry ingredients in such aqueous laundry detergent compositions. These interactions can be minimized by keeping the ingredients dry, for example by incorporating them in laundry detergents or tablets. However, dry detergents for washing disperse more slowly and, therefore, do not fully overcome the risk of bleaching stains. Additionally, many consumers have the desire to avoid the additional stage of filling the dosing device, which is usually required when using liquid detergent compositions for washing.

Accordingly, there remains a need for an easy-to-use liquid detergent for washing with a whitening system, which is stable and acceptable for use in a wide range of washing temperatures, including at low temperatures, and also virtually eliminates the risk of tissue damage due to bleaching stains.

SUMMARY OF THE INVENTION

The present invention relates to a laundry product with a standard dose of detergent, comprising: an anionic and / or nonionic surfactant and a whitening system, comprising: an organic whitening catalyst consisting of an aryliminium ion selected from the group of cations, zwitterions and mixtures thereof, as well as a source of activated peroxygen selected from the group consisting of a preformed peracid; a source of hydrogen peroxide and mixtures thereof; enclosed in a water-soluble or dispersible film, with at least 50% by weight of an anionic and / or nonionic surfactant, and at least 50% by weight of aryliminium ions contained in at least one liquid composition .

DETAILED DESCRIPTION OF THE INVENTION

As used in this application, “Laundry product with a standard dose of detergent” refers to any composition for processing a wash in a standard unit dose. A laundry product with a standard dose of detergent in accordance with the present invention contains at least one “compartment containing liquid” and may optionally contain a solid component. In the presence of a solid component, it may be in a separate compartment, may be suspended in a fluid-filled compartment, or as a part of a paste. A liquid-filled compartment refers to a partition of a laundry product with a standard dose of detergent containing liquid capable of wetting a fabric, such as clothing. The term liquid includes such forms as liquids, gels and pastes. The liquid contained in the compartment containing the liquid may include solid particles or gases in an acceptable subdivided form, but excludes forms that are not completely liquid, such as tablets or granules.

All percentages, ratios and proportions used in this application are mass percent of the encapsulated portion of the laundry product with a standard dose of detergent (including products with multiple compartments where appropriate), unless otherwise indicated. That is, excluding the mass of the encapsulating material. All average values are calculated “by weight” of the encapsulated portion, unless otherwise indicated. Unless otherwise specified, pH is measured on a clean composition at 21 ° C using a Thermo Electron Corporation Orion 261S pH meter with a gel probe (Orion Triode Combination pH / ATC probe, Model No. 9107WP), calibrated in accordance with the instruction manual.

Laundry products with a standard dose of detergent

Laundry products with a standard dose of detergent in accordance with the present invention include, in a standard, easy to use dosage form: an anionic and / or nonionic surfactant, aryliminium ion and a source of activated peroxygen. Such unit dose products have the advantage of ensuring the correct dosage of delivered whitening ingredients. In order to achieve an optimal bleaching characteristic, the amount of arylaminium ions and the source of activated peroxygen, as well as their ratio, are preferably carefully controlled. A detergent product with a standard dose of detergent also preferably contains anionic surfactants, non-soap substances, other surfactants, especially additional non-ionic surfactants, non-amino functional organic solvents and laundry additives to improve cleaning and care of the fabric.

A laundry product with a standard dose of detergent contains one or more compartments. A multi-compartment unit dosage form may be desirable for reasons such as separation of chemically incompatible ingredients, or where desired, part of the ingredients should be released in the wash sooner or later.

Anionic and nonionic surfactants

The detergent compositions in accordance with the present invention contain, preferably from 1% to 70%, more preferably from 10% to 50%, and most preferably from 15% to 45% by weight of an anionic and / or nonionic surfactant.

Anionic surfactants: Laundry products with a standard dose of detergent in accordance with the present invention preferably contain from 1 to 70%, more preferably from 5 to 50% by weight of one or more anionic surfactants. Preferred anionic surfactants are selected from the group consisting of: C11-C18 alkylbenzenesulfonates, C10-C20 branched chain alkyl sulfates and random alkyl sulfates, C10-C18 alkyl ethoxyl sulfates, middle branched chain sulfates, middle-chain alkyl sulfoxyl sulfates, C10 alkyl sulfoxyl sulfates containing 1-5 ethoxy units, modified alkylbenzene sulfonates, C12-C20 methyl ether sulfonate, C10-C18 alpha olefin sulfonate, C6-C20 sulfosuccinates, and mixtures thereof. However, by nature, each anionic surfactant known in the field of detergent compositions can be used, for example, as described in the Surfactant Science Series, Vol. 7, edited by W. M. Linfield, Marcel Dekker. However, the compositions of the present invention preferably comprise at least one sulfonic acid surfactant, such as a linear alkylbenzenesulfonic acid, or water-soluble salt forms.

Suitable anionic sulfonate surfactants or sulfonic acid surfactants for use in this application include acid or salt forms of linear or branched C5-C20, more preferably C10-C16, most preferably C11-C13 alkylbenzenesulfonates, C5-C20 alkyl ethersulfonates , C6-C22 primary or secondary alkanesulfonates, C5-C20 sulfonated polycarboxylic acids and mixtures thereof. The above surfactants can vary widely in the content of the 2-phenyl isomer. Anionic sulfate salts suitable for use in the compositions of the present invention include: primary and secondary alkyl sulfates having a linear or branched alkyl or alkenyl moiety containing from 9 to 22 carbon atoms, more preferably from 12 to 18 carbon atoms; beta-branched alkyl sulfate surfactants, as well as mixtures thereof. Branched chain alkyl sulfates or sulfonates are also suitable anionic surfactants for use in the compositions of the present invention. Preferred are C5-C22, preferably C10-C20, branched chain primary alkyl sulfates. If mixtures are used, an acceptable average total number of carbon atoms in the alkyl moieties is preferably in the range of 14.5 to 17.5. Preferred mono-methyl branched primary alkyl sulfates are selected from the group consisting of from 3-methyl to 13-methylpentadecanol sulfates, the corresponding hexadecanol sulfates, and mixtures thereof. Dimethyl derivatives or other biodegradable alkyl sulfates having a slight branching may be used in a similar manner. Other suitable anionic surfactants for use in this application include fatty methyl ether sulfonates and / or alkyl ethoxy sulfates (AES) and / or alkyl polyalkoxylated carboxylates (AEC). Mixtures of anionic surfactants can be used, for example, mixtures of alkylbenzenesulfonates and AES.

Anionic surfactants are typically present in the form of their salts with alkanolamines or alkali metals such as sodium and potassium. Preferably, the anionic surfactants are neutralized by alkanolamines, such as monoethanolamine or triethanolamine, and are completely soluble in the liquid phase.

Non-ionic surfactants: Laundry products with a standard dose of detergent in accordance with the present invention may contain from 1 to 70%, preferably from 5 to 50% by weight of non-ionic surfactant. Suitable nonionic surfactants include, but are not limited to, C12-C18 alkyl ethoxylates ("AE"), including so-called narrow peak alkyl ethoxylates, C6-C12 alkyl phenol alkoxylates (especially ethoxylates and mixed ethoxy / propoxy), a C6- alkylene oxide condensate C12 alkyl phenols, alkylene oxide condensates of C8-C22 alkanols and ethylene oxide / propylene oxide block polymers (Pluronic®-BASF Corp.), as well as semi-polar non-ionic substances (e.g. amine oxides and phosphine oxides). A comprehensive description of acceptable non-ionic surfactants can be found in US Pat. No. 3,929,678.

Alkyl polysaccharides, such as those described in US Pat. No. 4,565,647, are also useful non-ionic surfactants in the compositions of the present invention. Alkyl polyglucoside surfactants are also suitable. In some embodiments, suitable non-ionic surfactants include those of formula R1 (OC ₂ H ₄ ) _n OH, where R1 is a C10-C16 alkyl group or a C8-C12 alkyl phenyl group, and n is from 3 to 80. In some embodiments non-ionic surfactants can be condensation products of C12-C15 alcohols with from 5 to 20 mol of ethylene oxide per mole of alcohol, for example, C12-C13 alcohol condenses with approximately 6.5 mol of ethylene oxide per mole of alcohol. Additional suitable non-ionic surfactants include fatty acid polyhydroxyamides of the formula:

where R is C9-C17 alkyl or alkenyl, R is a methyl group, and Z is glycidyl derived from reduced sugar or alkoxylated derivatives thereof. Examples are N-methyl N-1-deoxyglycyl cocoamide and N-methyl N-1-deoxyglycyl oleamide.

Whitening systems

A laundry product with a standard dose of detergent contains an organic bleaching catalyst and a source of activated peroxygen. Such organic whitening catalysts improve whitening performance, especially at low temperatures. They are able to take an oxygen atom from a source of activated peroxygen and transfer an oxygen atom to an oxidizable substrate.

The organic whitening catalyst according to the present invention includes an aryliminium ion. Aryliminium ions can be cations, zwitterions, or a mixture thereof. To ensure the rapid distribution of aryliminium ions throughout the wash, at least 50%, preferably at least 80%, more preferably 100%, by weight of aryliminium ions are contained in the compartment containing the liquid, laundry products with a standard dose of detergent facilities. A laundry product with a standard dose of detergent may contain from 0.001% to 10%, preferably from 0.01% to 5%, more preferably from 0.1% to 2% by weight of aryliminium ions. A laundry product with a standard dose of detergent may contain from 0.1% to 30%, preferably from 0.5% to 20%, more preferably from 1% to 10% by weight of a source of activated peroxygen. Aryliminium ions in accordance with the present invention react with sources of activated peroxygens, such as peracids, to form aryloxaziridinium ions that bleach oxidizable substrates.

In order to obtain the maximum beneficial effect of aryliminium ion and to minimize its decomposition, the laundry product with a standard dose of detergent preferably contains a mass ratio of aryliminium ion and source of activated peroxygen from 2: 1 to 1: 500, preferably from 1: 1 to 1: 100, more preferably from 1: 5 to 1:50, even more preferably from 1:10 to 1:30.

Additionally, the stability of aryliminium ions (and the resulting aryloxaziridinium ions) depends on the washing temperature in dilutions that are typically found in the washing solution. At lower washing temperatures, for example, from 5 ° C to 30 ° C, the decomposition rate of organic bleaching catalysts is reduced, compared with the speed at higher washing temperatures, for example, above 40 ° C. In contrast, typical bleaching agents, such as peroxides with or without bleaching activators, are less effective at lower washing temperatures. Thus, aryliminium ions are especially useful for increasing the efficiency of bleaching systems for low washing temperatures.

The bleaching system for use in the present invention may also include other bleaching agents, such as bleaching activators, metal-containing bleaching catalysts, transition metal complexes of macropolycyclic hard ligands, and mixtures thereof.

1) Organic Whitening Catalyst

Aryliminium zwitterions: Suitable aryliminium zwitterions can be selected from the group consisting of:

where: in Figure 1, R ^{1 is} selected from the group consisting of H, a branched alkyl group containing from 3 to 24 carbon atoms, and a linear alkyl group containing from 1 to 24 carbon atoms.

Preferably, R ^{2 is} independently selected from H and methyl groups, n is an integer from 0 to 1;

where: in Figure 3, R ¹ represents a branched alkyl group containing from 9 to 24 carbon atoms, or a linear alkyl group containing from 11 to 24 carbon atoms, preferably each R represents a branched alkyl group containing from 9 to 18 carbon atoms or a linear alkyl group containing from 11 to 18 carbon atoms, more preferably each R ^{1 is} selected from the group consisting of 2-propylheptyl, 2-butyl octyl, 2-pentylnonyl, 2-hexyldecyl, n-dodecyl, n-tetradecyl, n- hexadecyl, n-octadecyl, iso noni and iso-decyl, iso-tridecyl and iso-pentadecyl. Suitable aryliminium zwitterions include those listed in Table 1a, Table 1b, and mixtures thereof. Preferred aryliminium zwitterions are those listed in Table 1b, and mixtures thereof. Most preferred are the internal salts of 3- (3,4-dihydroisoquinolinium) propane sulfonate, mono- [2- (3,4-dihydroisoquinolin-2-yl) -1- (2-butyl-octyloxymethyl) ethyl] sulfuric acid ester and their mixtures. Other suitable examples of organic whitening catalysts can be found in US 5,576,282 and US 5,817,614, EP 923,636 B1, WO 2001/16263 A1, WO 2000/42156 A1, WO 2007/001262 A1.

Aryliminium cations: Suitable cations and polycations include aryliminium ions having the structure:

where: in Figure 4, R ^{3 is} independently selected from the group consisting of H and methyl groups. Preferably, R ³ is H. R ⁴ and R ⁵ are independently selected from the group consisting of H, a branched alkyl group having from 3 to 12 carbon atoms, and linear alkyl group containing from 1 to 12 carbon atoms. Preferably, R ⁴ and R ⁵ are H or methyl, more preferably R ⁴ and R ⁵ are H. X ^- is a counterionic charge balancer, preferably compatible with a bleach counterion.

Most preferred are N-methyl-3,4-dihydroisoquinolinium tetrafluoroborate, N-methyl-3,4-dihydroisoquinolinium p-toluenesulfonate, and mixtures thereof.

The stability of the aryliminium ion is improved when the compartment containing the liquid in which the aryliminium ion is present has an undiluted pH of less than 9, preferably less than 8.5, more preferably less than 8, even more preferably less than 7. In another preferred embodiment, The pH of the compartment containing the liquid in which the aryliminium ion is located is 5 to 7.

2) Sources of activated peroxygen

Sources of activated peroxygen supply oxygen atoms, which are transferred to the oxidizable substrate and, thus, are one of the main elements of the bleaching system. The source of activated peroxygen is selected from the group consisting of a preformed peracid, a source of hydrogen peroxide, and mixtures thereof.

To improve stability before use, the source of activated peroxygen is preferably at least partially physically separated from the aryliminium ions, so that the source of activated peroxygen and the organic whitening catalyst cannot chemically interact. In one embodiment, at least 50%, preferably 80%, more preferably 100% by weight of the source of activated peroxygen is solid. In such embodiments, the catalyzed decomposition of the peroxygen source of aryliminium ions is inhibited by the interface between the solid and liquid phases. In another embodiment, at least 50%, preferably 80%, more preferably 100% by weight of the source of activated peroxygen is encapsulated by a water-soluble or dispersible barrier that retains most sources of activated peroxygen isolated from aryliminium ions. Acceptable water-soluble or dispersible barrier materials include carbohydrates, natural or synthetic resins, chitin and chitosan, cellulose and cellulose derivatives, polyvinyl alcohol and polyvinyl alcohol derivatives, polyvinyl acetate, polyethylene glycol, synthetic and natural waxes, gelatin, alginates, acrylic polymers and materials, inorganic coatings (silicates, phosphates, carbonates, zeolites, alumina and mixtures thereof), urea-formaldehyde, melamine-formaldehyde, fatty acids, poly etany, polyamides, polyureas, polyesters, and mixtures thereof. In yet another embodiment, at least 50%, preferably at least 80%, more preferably 100% by weight of the source of activated peroxygen is in another compartment containing less than 25%, preferably less than 10%, more preferably less than 1% by weight of aryliminium ions.

By similar means, the source of activated peroxygen can be physically separated from ingredients, such as enzymes and perfumes, which are sensitive to bleaching agents. Such embodiments include laundry products with a standard dose of detergent, further comprising a washing enzyme selected from the group consisting of: lipase, protease, amylase, cellulase, lyase pectate, xyloglucanase, and mixtures thereof, in which at least a portion of the activated source peroxygen is physically separated from the washing enzyme by means selected from the group consisting of at least 50%, preferably 80%, more preferably 100% by weight of the source of activated peroxygen, which is solid, according to at least 50%, preferably 80%, more preferably 100% by weight of the source of activated peroxygen encapsulated by a water-soluble or dispersible barrier, and at least 50%, preferably 80%, more preferably 100% by weight of the source of activated peroxygen another compartment containing less than 25%, preferably less than 10%, more preferably less than 1% by weight of washing enzymes. In another such embodiment, a laundry product with a standard dose of detergent, further comprising a perfume, in which at least a portion of the activated peroxygen source is physically separated from the perfume by means selected from the group consisting of at least 50%, preferably 80%, more preferably 100% by weight of the source of activated peroxygen, which is a solid, at least 50%, preferably 80%, more preferably 100% by weight of the source of activated peroxygen, encapsulation of a water-soluble or dispersible barrier, and at least 50%, preferably 80%, more preferably 100% by weight of the source of activated peroxygen are in another compartment containing less than 25%, preferably less than 10%, more preferably less than 1% by weight of perfume.

Preformed peracids: Acceptable preformed peracids include, but are not limited to, compounds selected from the group consisting of phthalimidoperoxicaproic acid (PAP), percarboxylic acids and salts, perugolic acids and salts, perimidic acids and salts, peroxymonosulfuric acids and salts, and their mixtures. Phthalimidoperoxicaproic acid (PAP) is preferred. A suitable salt of peroxymonosulfuric acid is potassium peroxymonosulfate (potassium monopersulfate) or its triple salt: 2KHSO ₅ · KHSO ₄ · K ₂ SO ₄ .

The stability of compartments containing a liquid containing a preformed peracid is improved when the pH in the undiluted state is from 4 to 10, preferably from 6.5 to 9, more preferably from 7 to 8.5. For example, peracids, such as phthalimidoperoxy-caproic acid, are less prone to ring opening in this pH range. It is believed that a greater amount of peracid is protonated in this pH range, which slows down the availability of peracid. This gives more time for the organic whitening booster to be distributed on the substrate, which leads to improved bleaching of spots.

In laundry products with a standard dose of detergent, the preformed peracid may be in the range of 0.1% to 30%, preferably 0.5% to 25%, more preferably 1% to 10%, most preferably 2% up to 4% by weight of the encapsulated part of the laundry product with a standard dose of detergent. Alternatively, for laundry products with a standard dose of detergent for use primarily as a bleaching additive, an even higher level of peracid may be present. For example, such compositions may contain from 10% to 40%, preferably from 15% to 30%, more preferably from 15% to 25% by weight of the preformed peracid. In one embodiment with multiple compartments with improved stability, at least 80% by weight of the preformed peracid is encapsulated in a compartment containing less than 25% by weight of aryliminium ions.

Sources of hydrogen peroxide: Suitable sources of hydrogen peroxide include: peroxides, persols, and mixtures thereof. Embodiments of the present invention may contain from 0.1% to 30%, preferably from 0.5% to 20%, more preferably from 1% to 10% by weight of a source of hydrogen peroxide. Hydrogen peroxide is one of the most powerful oxidizing agents known. This highly selective bleaching agent causes less damage to textile fibers compared to many other sources of peroxygen and tends to be less aggressive for fabric dyes, washing enzymes and optical brighteners. When incorporated into laundry products with a standard dose of detergent in accordance with the present invention, additional levels of from 0.1% to 10%, preferably from 0.5 to 5% by weight of hydrogen peroxide, are preferred. Suitable peroxides are also organic peroxides, such as diacyl peroxides, which do not cause visible stains or films. One example is dibenzoyl peroxide. Other suitable sources of hydrogen peroxide are described in detail in Kirk Othmer's Encyclopaedia of Chemical Technology, 4th Ed (1992, John Wiley & Sons), Vol.4, pp.271-300 "Bleaching Agents (Survey)".

Suitable persols include: percarbonates, perborates, persulfates, perphosphates, persilicates. Percarbonates and perborates are preferred. Percarbonates are particularly preferred because of their greater dissolution rate, more environmentally friendly profile and the advantage of simultaneously generating hydrogen peroxide, as well as the release of carbonate. Thus, they give a higher pH than perborates and promote perhydrolysis. Sodium percarbonate is an acceptable percarbonate. Sources of perborates, such as sodium perborate, have good stability and selectivity. Other preferred sources of perborates include tetrahydrate and / or monohydrate. To improve stability, persal may be coated.

3) Other whitening agents

Whitening Activators: The whitening system in accordance with the present invention can be obtained with a whitening activator in combination with persal and / or peroxide. Persols, in particular percarbonates and / or perborates, are preferred. An example of a suitable peroxide is dibenzoyl peroxide. In use, the whitening activator is preferably selected from the group consisting of: nonanoyloxybenzenesulfonate (NOBS), sodium 4- (isononanoyloxy) benzenesulfonate (iso-NOBS), tetraacetylethylenediamine (TAED), or mixtures thereof. They can be present at levels from 0.01 to 15%, preferably from 0.5 to 10%, more preferably from 1% to 8% by weight. If lipase enzymes are included in the laundry product with a standard dose of detergent, sodium 4- (isononanoyloxy) benzenesulfonate is particularly preferred since, unlike other bleaching activators, it is very compatible with lipase. Diacyl peroxide (DAP) formed by the reaction of iso-NOBS with a C9 peroxy acid derived from iso-NOBS is also compatible with lipase. Other suitable whitening activators can be selected from the group consisting of: benzoylcaprolactam (BzCL), 4-nitrobenzoylcaprolactam, 3-chlorobenzoylcaprolactam, benzoyloxybenzenesulfonate (PhBz), decanoyloxybenzenesulfonate (PhBz), benzoylobenzenesulfonate (PhBz), benzoyl (benzo-sulfonate (PhBz), benzene C8-OBS), perhydrolyzable esters and mixtures thereof, alternatively benzoyl caprolactam and benzoyl valerolactam, 4- [N- (nonanoyl) amino hexanoyloxy] benzene sulfonate sodium salt (NACA-OBS) (see US 5,523,434), benzodosulfonyl sulfonoxy or 12-OBS), 10-undecenoyloxybenzenesulfonate (UDOBS or C11-OBS with unsaturation at 10 position), and decanoyloxybenzoic acid (DOBA) and mixtures thereof. Non-limiting examples of acceptable whitening activators, including quaternary substituted whitening activators, are described in US 6,855,680. Alternatively, an aryliminium ion may be selected to include whitening activation properties.

Metal-containing bleaching catalysts: Preferred bleaching catalysts include manganese and cobalt-containing bleaching catalysts. Other suitable metal-containing bleaching catalysts include catalyst systems containing a transition metal cation with a specific bleaching catalytic activity, such as copper, iron, titanium, ruthenium, tungsten, molybdenum or manganese cations; an auxiliary metal cation having little or no bleaching catalytic activity, such as zinc or aluminum cations, and a sequestrant having certain stability constants for metal catalytic and auxiliary cations, in particular ethylenediaminetetraacetic acid, ethylene diamine tetra (methylene phosphonic acid) and its water-soluble salts . Suitable catalyst systems are described in US 4,430,243.

Transition metal complexes: Laundry products with a standard dose of detergent in this application may also include bleaching catalysts containing a transition metal complex, preferably with a macropolycyclic rigid ligand. The amount used is preferably from 0.0001% to 5%, more preferably from 0.001% to 2%, most preferably from 0.01% to 1% by weight of the encapsulated portion of the laundry product with a standard dose of detergent.

Some of the optional ingredients that can be used are described in more detail as follows:

Additional surfactants: Laundry products with a standard dose of detergent in accordance with the present invention may contain an additional surfactant selected from the group consisting of: anionic, cationic, nonionic, amphoteric and / or zwitterionic surfactants and their mixtures.

Suitable cationic surfactants may be water-soluble, dispersible in water or insoluble in water. Such cationic surfactants have at least one quaternized nitrogen atom and at least one long chain hydrocarbyl group. Compounds containing two, three or even four long chain hydrocarbyl groups are also included. Examples include alkyltrimethylammonium salts such as C12 alkyltrimethylammonium chloride, or hydroxyalkyl substituted analogs thereof. The present invention may contain 1% or more cationic surfactants.

Amphoteric detergent surfactants suitable for use in the composition include surfactants that are widely described as derivatives of aliphatic secondary and tertiary amines, in which the aliphatic radical may be straight or branched chain, and in which one of the aliphatic substituents contains 8 to 18 carbon atoms and the other contains an anionic group such as carboxy, sulfonate, sulfate, phosphate or phosphonate. Suitable amphoteric detergent surfactants for use in the present invention include, but are not limited to: cocoamphoacetate, cocoamphodiacetate, lauroamphoacetate, lauroamphodiacetate, and mixtures thereof.

Zwitterionic detergent surfactants suitable for use in standard dose detergent washing products are well known in the art and include surfactants that are widely described as derivatives of aliphatic quaternary ammonium, phosphonium and sulfonium compounds in which aliphatic radicals can be a straight or branched chain, and in which one of the aliphatic substituents contains from 8 to 18 carbon atoms and the other contains an anionic group, such as carboxy, sulfonate, sulfate, phosphate or phosphonate. Zwitterions, such as betaines, are also suitable for the present invention. Additionally, amine oxide surfactants having the formula: R (EO) _x (PO) _y (BO) _z N (O) (CH ₂ R ′) ₂ · qHO are also useful in the compositions of the present invention. R is a relatively long chain hydrocarbyl moiety which may be saturated or unsaturated, linear or branched, and may contain from 8 to 20, preferably from 10 to 16 carbon atoms, and more preferably is C12-C16 primary alkyl. R ′ is a short chain moiety which is preferably selected from hydrogen, methyl and —CH ₂ OH. If x + y + z is other than 0, then EO is ethyleneoxy, PO is propyleneenoxy and BO is butyleneoxy. Aminoxide surfactants are illustrated by C12-C14 alkyldimethylamine oxide.

Non-limiting examples of other anionic, zwitterionic, amphoteric or optional additional surfactants suitable for use in the compositions are described in McCutcheon's, Emulsifiers and Detergents, 1989 Annual, published in M.S. Publishing Co., and U.S. Patent Nos. 3,929,678,2668,072; 2,438,091; 2,528,378.

Water and / or non-amino functional organic solvent: compartments containing liquid, laundry products with a standard dose of detergent preferably contain less than 20%, more preferably less than 15%, most preferably less than 10% by weight of water. Alternatively, in the compartment containing the liquid, it may be almost completely non-aqueous, preferably containing from 2% to 40%, more preferably from 5 to 25% by weight of a non-amino functional organic solvent.
