Definitions
- the present invention relates to detergent compositions which comprise selected ingredients, including selected quatemized ethoxylated, alkylene diiamine compounds.
- laundry detergents and other cleaning compositions present a considerable challenge, since modem compositions are required to remove a variety of soils and stains from diverse substrates.
- laundry detergents, hard surface cleaners, shampoos and other personal cleansing compositions, hand dishwashing detergents and detergent compositions suitable for use in automatic dishwashers, and the like all require the proper selection and combination of ingredients in order to function effectively.
- such detergent compositions will contain one or more types of surfactants which are designed to loosen and remove certain soils and stains.
- some detergent adjuncts and surfactants exhibit optimal performance on certain types of soils and stains, they can actually diminish performance on other soils.
- surfactants which remove greasy/oily soils from fabrics can sometimes be sub-optimal for removing particulate soils.
- the soils once removed from the substrate should be dispersed or suspended in the wash liquor to minimize redeposition on the substrate.
- Clay soil particles generally comprise negatively charged layers of aluminosilicates and positively charged cations (e.g. calcium) which are positioned between and hold together the negatively charged layers.
- a variety of models can be proposed for compounds which would have clay soil removal properties.
- One model requires that the compound have two distinct characteristics. The first is the ability of the compound to adsorb onto the negatively charged layers of the clay particle. The second is the ability of the compound, once adsorbed, to push apart (swell) the negatively charged layers so that the clay particle loses its cohesive force and can be removed in the wash water.
- a model proposed for the anti-redeposition action of the positively charged anti-redeposition compounds is as follows. Adsorption of the positively charged molecule on the surface of clay particles in the wash water gives the particles the dispersancy properties of the molecule. As more and more of these compounds adsorb onto the suspended clay soil particles, the latter become encased within a hydrophilic layer. As such, the hydrophilically encased soil is prevented from redepositing on fabrics, in particular hydrophobic fabrics such as polyester, during the laundering cycle.
- AQD alkoxylated quaternary diamine
- the AQD soil removal/dispersants used in the present manner provide substantial advantages to the formulator over other dispersants known heretofore.
- the AQD dispersants herein are compatible with the preferred alkyl sulfate, alkyl ethoxylated sulfate, and amidopropylamine detersive surfactants.
- the AQD dispersants are formulatable over a broad pH range from 5 to 12.
- the AQD dispersants are also compatible with various perfume ingredients, unlike other quats known in the art.
- the AQD dispersants herein appear to minimize or eliminate redeposition of fatty acids/oily materials present in an aqueous laundry liquor back onto fabrics which have been previously soiled with body soils. Accordingly, the AQD dispersants herein have now been found to prevent the redeposition of polar lipids from an aqueous laundry bath back onto fabrics from whence body soils have been removed through the laundering process. Stated otherwise, in a laundering liquor, the AQD dispersants herein remove such polar lipids and keep them suspended in the aqueous medium, rather than allowing them to redeposit onto the cleaned fabrics.
- the AQD dispersants herein are surprisingly compatible with the polyanionic materials such as polyacrylates and acrylate/maleate copolymers which are used to provide a builder and/or dispersant function with many conventional detersive surfactants.
- the combination of the AQD dispersants herein with specific ethoxylated polyethyleneimines with a MW of less than about 5,000 provide synergistic cleaning benefits.
- Other advantages for the AQD dispersant herein include their ability to enhance enzymatic cleaning and fabric care performance in a laundering liquor. While not intending to be limited by theory, it is speculated that enzymes may be partially denatured by conventional anionic surfactants.
- the AQD dispersants herein provide substantial cleaning enhancement with respect to clay soil removal from fabrics, as compared with conventional detergent mixtures. Again, while not intending to be limited by theory, it may be speculated that conventional cationic surfactants associate with the clay in "close-packed” fashion and render the clay more difficult to remove. In contrast, the alkoxylated AQD dispersants are believed to provide more open associations with clays, which are then more readily removed from fabric surfaces. Whatever the reason, the compositions herein containing the AQD dispersants provide improved performance over conventional dispersants with special regard to clay soil removal.
- compositions without bleach the formulator my choose to use somewhat higher levels of AQD dispersants to provide enhanced performance benefits.
- These benefits may be associated with the ability of the AQD dispersants herein to modify the solution characteristics of conventional anionic surfactants such as alkyl sulfates or alkyl ethoxylated sulfates to allow more of the surfactants to be available to perform their cleaning function.
- the detergent composition is "underbuilt” with respect to calcium and/or magnesium water hardness ions
- Mixtures of AQD dispersants can be blended and used to provide a broad spectrum of cleaning performance over a wide variety of soils and stains and under a wide range of usage conditions. Representative, but non-limiting, examples of such combinations of AQD dispersants are disclosed in the Examples hereinafter.
- the AQD dispersants used in the manner of the present invention, successfully address many of the problems associated with the formulation of modem, high- performance detergent compositions.
- these dispersants allow the formulation of effective laundry compositions which can be used to remove a wide variety of soils and stains under a wide spectrum of usage conditions.
- the present invention relates to cleaning compositions comprising or prepared by combining an effective amount of certain alkoxylated (especially ethoxylated) quaternary poly amine dispersants and one or more detersive (including fabric care) adjuncts, as disclosed hereinafter.
- alkoxylated quaternary diamine (AQD) dispersants used in the present invention are of the general formula:
- R is selected from linear or branched C2-C12 alkylene, C3-C12 hydroxyalkylene, C4-C12 dihydroxyalkylene, Cg-Ci2 dialkylarylene, [(CH2CH2 ⁇ ) q CH2CH2J- and - CH 2 CH(OH)CH2 ⁇ -(CH2CH2 ⁇ ) q CH2CH(OH)CH2j- where q is from about 1 to about 100.
- Each R ⁇ is independently selected from C1-C4 alkyl, C7-C12 alkylaryl, or A.
- A is of the formula:
- R3 where R3 is selected from H or C1-C3 alkyl, n is from about 5 to about 100 and B is selected from H, C1-C4 alkyl, acetyl, or benzoyl; X is a water soluble anion
- R is selected from C4 to Cg alkylene
- R ⁇ is selected from C ⁇ -C2 alkyl or C2-C3 hydroxyalkyl
- A is:
- R3 where R3 is selected from H or methyl, and n is from about 10 to about 50.
- R is linear or branched Cg
- Rl is methyl
- R3 is H
- n is from about 20 to about 50.
- AQD's can be synthesized following the methods outline in US. Patent No. 4,664,848, or other ways known to those skilled in the art.
- the levels of the AQD dispersants used to prepare finished laundry detergent compositions can range from about 0.1% to about 10%, typically from about 0.4% to about 5%, by weight.
- the present invention encompasses the use of the aforesaid AQD dispersants to enhance the overall cleaning performance of detergent compositions which contain otherwise known ingredients. It has now been discovered that the overall cleaning performance of such detergent compositions can be improved by the incorporation of relatively small quantities of the AQD dispersants. Surprisingly, laundry cleaning performance with respect not only to greasy soils, but also body soil, builder sensitive soil, bleach sensitive soil, as well as food stains and sock soil is enhanced.
- the usage levels and mode of use of the AQD dispersants in detergent formulations of various types will depend on the desires of the formulator. Representative, but non- limiting, examples of such formulations include the following.

- Such stains and soils are removed from fabrics such as cotton, polyester/cotton blends (P/C) and double-knit polyester (DKPE).
- the method comprises contacting fabrics in need of removal of such soils with an effective amount of the compositions herein, in the presence of water, and preferably with agitation.
- Various suitable usage levels and methods are disclosed hereinafter.
- the AQD compounds herein have the advantage that they are commercially available and are compatible with the various detersive ingredients such as builders, detersive enzymes, and the like, which are used in many modem, high quality, fully-formulated laundry detergents. Moreover, the AQD compounds exhibit satisfactory stability in the presence of the bleach ingredients commonly used in laundry detergent-plus-bleach compositions. Importantly, the AQD dispersants herein exhibit superior performance with respect to the removal of body soils and everyday soils such as sock soil. In short, the compositions herein provide improved performance for cleaning a broad spectrum of soils and stains including body soils from collars and cuffs, greasy soils, and enzyme/bleach sensitive stains such as spinach and coffee. The compositions herein also provide excellent cleaning on builder sensitive stains such as clay, and thus are especially useful in a nil-P context.
- the AQD dispersants herein provide improved fabric cleaning performance in the presence of bleach. This improvement in cleaning is seen at usage levels as low as 3 parts per million (ppm) of the AQD in the laundry liquor and is believed to be associated with increased perhydrolysis.
- the AQD dispersants herein provide improved (even synergistic) performance with amylase, especially Duramyl®, and lipase, especially Lipolase Ultra®, enzymes. This improvement is seen especially in the absence of bleach.
- this invention provides a means for enhancing the removal of greasy/oily soils by combining a lipase enzyme with an AQD dispersant.

- Particularly preferred amines include those selected from the group consisting of octyl amine, hexyl amine, decyl amine, dodecyl amine, Cg-Ci 2 bis(hydroxyethyl)amine, Cg-Ci 2 bis(hydroxyisopropyl)amine, and Cg-Ci 2 amido-propyl dimethyl amine, and mixtures.
- This invention also provides detergent compositions which deliver effective cleaning of greasy/oily everyday soils via use of percarbonate bleach with an AQD dispersants as disclosed herein.
- Percarbonate which delivers peroxide bleach into the wash, is a cornerstone technology of mode , ultra-compact granular laundry detergent formulas.
- Peroxide bleach is very hydrophilic and, while it cannot match the bleaching effectiveness delivered by peracids (formed for example from peroxide interaction with TAED), it is effective at decoloration of pigments (e.g., in particulates or beverage stains) and also can help remove the color from the organic residues associated with body soils.
- compositions containing AQD dispersants and percarbonate bleach deliver superior cleaning and whiteness performance.
- This invention also provides detergent compositions which deliver effective cleaning of greasy/oily everyday soils by means of hydrophobic bleach activators used in combination with a water-soluble AQD dispersant of the present type. Everyday soil cleaning and whiteness benefits for hydrophobic bleach activators and peracids have already been demonstrated. Such materials are, to a limited degree, able to penetrate complex/greasy oily soils. It has now been found that detergent and bleach compositions containing AQD and hydrophobic bleach activators (including preformed peracids) deliver superior cleaning and whiteness performance.
- This invention also provides detergent compositions which deliver effective cleaning of greasy/oily "everyday” soils (and accidental soils), via use of polyethoxyated-polyamine polymers (PPP) with the AQD dispersants herein.
- PPP polyethoxyated-polyamine polymers
- greasy/oily "everyday” soils e.g., on collars, pillowcases
- PPP polyethoxyated-polyamine polymers
- Characteristic features of these materials include: (1) a reasonably low molecular weight "hydrophobic" polyamine backbone (which is slightly cationic in nature providing an affinity for soils and fabrics); and (2) pendant "hydrophilic" polyethoxylate groups which provide steric stabilization and greasy soil suspension. During the wash, these polymers work at the stain/wash liquor interface.
- detergent compositions containing the AQD dispersants herein and polyethoxylated-polyamine polymers deliver superior cleaning and whiteness performance vs. compositions containing either technology alone.
- Benefits for the mixed system are believed to be the result of: (1) AQD action on the stain surface to prevent lime soap formation and to lift off any calcium soaps present, thereby facilitating improved polymer deposition; (2) AQD providing solubilization deep into the soil, while the polymer acts as a "grease removal shuttle", stripping out the AQD-solubilized stain components and dispersing them into the wash liquor.
- the preferred polyethoxylated-polyamines useful herein are generally polyalkyleneamines (PAA's), polyalkyleneimines (PAI's), preferably polyethyleneamine (PEA's), polyethyleneimines (PEI's), or PEA's or PEI's connected by moieties having longer R units than the parent PAA's, PAI's, PEA's or PEI's.
- a common polyalkyleneamine (PAA) is tetrabutylenepentamine. PEA's are obtained by reactions involving ammonia and ethylene dichloride, followed by fractional distillation. The common PEA's obtained are triethylenetetramine (TETA) and teraethylenepentamine (TEPA).
- the cogenerically derived mixture does not appear to separate by distillation and can include other materials such as cyclic amines and particularly piperazines. There can also be present cyclic amines with side chains in which nitrogen atoms appear. See U.S. Patent 2,792,372, Dickinson, issued May 14, 1957, which describes the preparation of PEA's.
- Preferred amine polymer backbones comprise R units that are C2 alkylene (ethylene) units, also known as polyethylenimines (PEI's).

- Preferred backbones, prior to modification have the general formula:
- PEI's prior to modification, will have a molecular weight greater than about 200 daltons.
- the relative proportions of primary, secondary and tertiary amine units in the polyamine backbone will vary, depending on the manner of preparation.
- Each hydrogen atom attached to each nitrogen atom of the polyamine backbone chain represents a potential site for subsequent substitution, quatemization or oxidation.
- polyamines can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc.
- a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc.

Enzyme Stabilizing System - The enzyme-containing compositions herein may optionally also comprise from about 0.001% to about 10%, preferably from about 0.005% to about 8%, most preferably from about 0.01% to about 6%, by weight of an enzyme stabilizing system.
- the enzyme stabilizing system can be any stabilizing system which is compatible with the detersive enzyme. Such a system may be inherently provided by other formulation actives, or be added separately, e.g., by the formulator or by a manufacturer of detergent-ready enzymes.
- Such stabilizing systems can, for example, comprise calcium ion, boric acid, propylene glycol, short chain carboxylic acids, boronic acids, and mixtures thereof, and are designed to address different stabilization problems depending on the type and physical form of the detergent composition.
- One stabilizing approach is the use of water-soluble sources of calcium and/or magnesium ions in the finished compositions which provide such ions to the enzymes.
- Calcium ions are generally more effective than magnesium ions and are prefe ⁇ ed herein if only one type of cation is being used.
- Typical detergent compositions, especially liquids will comprise from about 1 to about 30, preferably from about 2 to about 20, more preferably from about 8 to about 12 millimoles of calcium ion per liter of finished detergent composition, though variation is possible depending on factors including the multiplicity, type and levels of enzymes incorporated.
- Preferably water-soluble calcium or magnesium salts are employed, including for example calcium chloride, calcium hydroxide, calcium formate, calcium malate, calcium maleate, calcium hydroxide and calcium acetate; more generally, calcium sulfate or magnesium salts co ⁇ esponding to the exemplified calcium salts may be used. Further increased levels of Calcium and/or Magnesium may of course be useful, for example for promoting the grease-cutting action of certain types of surfactant.
- Borate stabilizers when used, may be at levels of up to 10% or more of the composition though more typically, levels of up to about 3% by weight of boric acid or other borate compounds such as borax or orthoborate are suitable for liquid detergent use.
- Substituted boric acids such as phenylboronic acid, butaneboronic acid, p- bromophenylboronic acid or the like can be used in place of boric acid and reduced levels of total boron in detergent compositions may be possible though the use of such substituted boron derivatives.
- Stabilizing systems of certain cleaning compositions may further comprise from 0 to about 10%, preferably from about 0.01% to about 6% by weight, of chlorine bleach scavengers, added to prevent chlorine bleach species present in many water supplies from attacking and inactivating the enzymes, especially under alkaline conditions.
- chlorine bleach scavengers While chlorine levels in water may be small, typically in the range from about 0.5 ppm to about 1.75 ppm, the available chlorine in the total volume of water that comes in contact with the enzyme, for example during dish- or fabric-washing, can be relatively large; accordingly, enzyme stability to chlorine in-use is sometimes problematic.
- Suitable chlorine scavenger anions are widely known and readily available, and, if used, can be salts containing ammonium cations with sulfite, bisulfite, thiosulfite, thiosulfate, iodide, etc.
- Antioxidants such as carbamate, ascorbate, etc., organic amines such as ethylenediaminetetracetic acid (EDTA) or alkali metal salt thereof, monoethanolamine (MEA), and mixtures thereof can likewise be used.
- EDTA ethylenediaminetetracetic acid
- MEA monoethanolamine
- special enzyme inhibition systems can be incorporated such that different enzymes have maximum compatibility.
- Other conventional scavengers such as bisulfate, nitrate, chloride, sources of hydrogen peroxide such as sodium perborate tetrahydrate, sodium perborate monohydrate and sodium percarbonate, as well as phosphate, condensed phosphate, acetate, benzoate, citrate, formate, lactate, malate, tartrate, salicylate, etc., and mixtures thereof can be used if desired.
- the chlorine scavenger function can be performed by ingredients separately listed under better recognized functions, (e.g., hydrogen peroxide sources), there is no absolute requirement to add a separate chlorine scavenger unless a compound performing that function to the desired extent is absent from an enzyme-containing embodiment of the invention; even then, the scavenger is added only for optimum results.
- the formulator will exercise a chemist's normal skill in avoiding the use of any enzyme scavenger or stabilizer which is majorly incompatible, as formulated, with other reactive ingredients.
- ammonium salts such salts can be simply admixed with the detergent composition but are prone to adsorb water and/or liberate ammonia during storage. Accordingly, such materials, if present, are desirably protected in a particle such as that described in US 4,652,392, Baginski et al.
- SRA Polymeric Soil Release Agent
- SRA's will generally comprise from 0.01% to 10.0%, typically from 0.1% to 5%, preferably from 0.2% to 3.0% by weight, of the composition.
- Prefe ⁇ ed SRA's typically have hydrophilic segments to hydrophilize the surface of hydrophobic fibers such as polyester and nylon, and hydrophobic segments to deposit upon hydrophobic fibers and remain adhered thereto through completion of washing and rinsing cycles thereby serving as an anchor for the hydrophilic segments. This can enable stains occurring subsequent to treatment with SRA to be more easily cleaned in later washing procedures.
