Description

Description: FIELD OF THE INVENTION The present invention relates to a detergent composition comprising an alkyl alkoxylated sulfate and a polyhydroxy fatty acid amide surfactant.

BACKGROUND OF THE INVENTION The ability of a detergent composition to clean a wide variety of stains and stains in cleaning many types of fabrics and other surfaces (e.g., hard surfaces, hair, etc.) contained in typical laundry is dependent on the performance of the detergent. Is very important in evaluating Surfactants which are considered to be important because of their good overall cleaning power and especially good cleaning performance of particulate soils include alkyl alkoxylated sulfate surfactants. While these surfactant systems have demonstrated excellent performance, it is desirable to provide a surfactant system that can be used for a wide variety of cleaning purposes while having enhanced grease and oil stain cleaning performance. One of the most common types of surfactants which have improved grease / oil cleaning performance in combination with alkyl alkoxylated surfactants is the alkyl benzene sulfonate, especially the type known as linear alkyl benzene sulfonate. These surfactants are capable of cleaning excellent greases / oils over a wide range of temperatures and conditions. However, alkylbenzene sulfonates are typically largely derived from petroleum-based feedstocks, and in recent years considerable attention has been paid to reducing petroleum consumption. Therefore, providing an equivalent level of overall cleaning performance by reducing or eliminating the amount of alkylbenzene sulfonate and instead using surfactants derived from natural renewable non-petroleum resources It would be desirable to provide an alkylalkoxylated sulfate detergent composition that can be cured.

While conventional nonionic surfactants can be combined with alkyl alkoxylated sulfates such as alkyl ethoxylates to provide satisfactory cleaning, effective grease / oil cleaning usually requires Requires relatively long wash times, high wash temperatures, and high surfactant concentrations.

The present invention relates to a laundry interface having excellent grease and other cleaning performance over a range of water temperatures and detergent concentrations by combining alkyl alkoxylated sulfates with certain polyhydroxy fatty acid amide surfactants. An activator system is provided. In addition, polyhydroxy fatty acid amides can be derived primarily or entirely from natural, renewable, non-petroleum feedstocks.

Foam Inhibitors Compounds that are known or have become known to reduce or inhibit foam formation can be incorporated into the compositions of the present invention. The incorporation of such materials (hereinafter referred to as "foam suppressants") is desirable because the polyhydroxyfatty acid amide surfactants of the present invention can increase the foam stability of the detergent composition. is there. Foam control can be particularly important when the detergent composition includes a relatively high foaming surfactant in combination with a polyhydroxy fatty acid amide surfactant. In compositions used in front-loading automatic washing machines, suppression of foam is particularly desirable. These machines are typically characterized by having a drum for holding the washing and washing water, these machines having a horizontal axis and a rotating action about that axis. As a result of this type of agitation, a large amount of foam may be formed, resulting in reduced cleaning performance. The use of suds suppressors can be very important under hot water washing conditions and also under high surfactant concentration conditions.

A wide variety of materials may be used in the compositions of the present invention as suds suppressors. Suds suppressors are well known to those skilled in the art. They are, for example, Kirk Othmer Encycl
opedia of Chemical Technology, Third Edition, Volume 7, 430
-447 (John Wiley & Sons, Inc., 1979). One type of foam suppressor that is of particular interest is:
Includes monocarboxylic fatty acids and their soluble salts. These materials are described in U.S. Pat. No. 2,954,347, issued Sep. 27, 1960 to Wayne St. John, the contents of which are incorporated herein by reference. To quote. Monocarboxylic fatty acids and salts thereof used as suds suppressors typically have 10 to about 24
It has a hydrocarbyl chain having carbon atoms, preferably 12 to 18 carbon atoms. Suitable salts include the alkali metal salts, such as sodium, potassium and lithium salts, and ammonium and alkanolammonium salts. These materials are a preferred class of suds suppressors for detergent compositions.

The detergent composition can also include a non-surfactant suds suppressor. These include, for example, high molecular weight hydrocarbons such as paraffin, fatty acid esters (eg, fatty acid triglycerides), fatty acid esters of monohydric alcohols, aliphatic
C ₁₈ -C ₄₀ ketones (e.g., stearone), and the like. Other suds suppressors include cyanuric chloride, 1-24
Primary or secondary amines having 2 carbon atoms 2 or 3
Molar, propylene oxide, and monostearyl phosphates, such as monostearyl alcohol phosphate, and tri-to- formed as products with monostearyl di-alkali metal (e.g., Na, K, Li) phosphate and phosphate esters. There are N-alkylated aminotriazines such as hexa-alkylmelamine or di- to tetra-alkyldiaminechlorotriazines. Hydrocarbons such as paraffins and haloparaffins can be used in liquid form. Liquid hydrocarbons are liquid at room temperature and atmospheric pressure and have a pour point of about -40
C. to about 5 ° C. with a minimum boiling point of at least 110 ° C.
(Atmospheric pressure). It is also known to use waxy hydrocarbons, preferably those with melting points below about 100 ° C. These hydrocarbons constitute a preferred class of suds suppressors for detergent compositions. Hydrocarbon foam inhibitors are described, for example, in 1981.
U.S. Pat. No. 4,265, issued to Gandolao et al.
No. 779, the contents of which are incorporated herein by reference. Thus, hydrocarbons include aliphatic, cycloaliphatic, aromatic and heterocyclic saturated or unsaturated hydrocarbons having about 12 to about 70 carbon atoms. The term "paraffin" as used in describing this suds suppressor is intended to encompass a mixture of true paraffins and cyclic hydrocarbons.

Another preferred class of non-surfactant suds suppressors include silicone suds suppressors. This class includes polyorganosiloxane oils such as polydimethylsiloxane, dispersions or emulsions of polyorganosiloxane oils or resins, and combinations of polyorganosiloxanes and silica particles, wherein the polyorganosiloxane is converted to silica. Those that are chemically adsorbed in a molten state are used. Silicone suds suppressors are well known in the art and are described, for example, in U.S. Pat. No. 4,265,779, issued May 5, 1981 to Gandolfo et al.
European Patent Application No. 89307851.9 published by rch, MS
The contents of these patent specifications are hereby incorporated by reference as though set forth in this specification.

Another silicone suds suppressor is disclosed in U.S. Pat. No. 3,455,839, which relates to compositions and methods for defoaming aqueous solutions by incorporating small amounts of a polydimethylsiloxane fluid.

Mixtures of silicone and silanized silica are described, for example, in German Patent Application DOS 2,124,526. Silicone defoamers and foam control agents in granular detergent compositions are disclosed in Bartolotta et al., U.S. Patent 3,933,672 and Baginski et al., U.S. Patent 4,652,392, issued March 24, 1987. I have.

Examples of silicone-based suds suppressors used herein include: (i) a polydimethylsiloxane fluid having a viscosity at 25 ° C. of about 20 cs to about 1500 cs; and (ii) (CH ₃ ) Consists of ₃ SiO _1/2 units and SiO ₂ units,
The ratio of (CH ₃ ) ₃ SiO _1/2 units to SiO ₂ units is about 0.6: 1
A foam comprising: (i) about 5 to about 50 parts per 100 parts by weight; and (iii) solid silica gel (i) about 1 to about 20 parts per 100 parts by weight. This is the amount of foam control of the regulator.

For any detergent composition used in an automatic washing machine, the foam should not form so much as to overflow from the washing machine. When a foam inhibitor is used, it is preferably contained in the “foam inhibiting amount”. By "foam control amount" is meant that the formulator of the composition selects the amount of the foam control agent such that the foam is sufficiently controlled to produce a low foaming laundry detergent for use in automatic washing machines. The amount of foam control agent will vary depending on the selected detergent. For example, in a high foaming surfactant,
The desired foam control is performed using a larger amount of foam control agent compared to the low foaming surfactant. Normally, a sufficient amount of suds suppressor is incorporated into the low foaming detergent composition and is added during the washing cycle of the automatic washing machine (when stirring the detergent in the aqueous solution under the given washing temperature and concentration conditions). The foam formed should not exceed about 75% of the porosity of the storage drum of the washing machine, preferably the foam should not exceed about 50% of said porosity. It is determined as the difference between the total volume of the drum and the volume of water and laundry.

The compositions of the present invention typically contain from 0% to about 5% suds suppressor. When used as suds suppressors, monocarboxylic acids and salts thereof are typically included in amounts up to about 5% by weight of the detergent composition. Preferably, about 0.5% to about 3% of a fatty acid monocarboxylate suds suppressor is used. Silicone suds suppressors are typically used in amounts up to about 2.0% by weight of the detergent composition, but higher amounts can be used. This upper limit is practical, primarily because it involves minimizing cost and retaining a small amount of effectiveness to effectively control foaming. Preferably, about 0.01% to about 1% of a silicone suds suppressor is used, and more preferably about 0.1%.
25% to about 0.5% is used. These weight percent values as used herein include polyorganosiloxanes and any silica that can be used in combination with any auxiliary materials that can be used.

Hydrocarbon suds suppressors typically comprise from about 0.01% to about 5.0%
, But larger amounts can be used. Monostearyl phosphate suds suppressors are typically used in amounts from about 0.1% to about 2% by weight of the composition.

Polymeric soil release agent Any polymeric soil release agent known to those skilled in the art can be used in the practice of the present invention. The polymeric soil release agent adheres to the hydrophobic fibers, such as polyester and nylon, to render the surface of the fibers hydrophilic, and remains attached until the wash and rinse cycle is completed. And a hydrophobic portion that functions as a fixing medium for the hydrophilic portion. Thereby, the stain existing after the treatment with the stain release agent can be more easily removed by the subsequent washing treatment.

It is beneficial to use a polymeric soil release agent in any of the detergent compositions of the present invention, especially in laundry or any other application that requires grease and oil removal from hydrophobic surfaces. However, the inclusion of polyhydroxyfatty acid amides in detergent compositions that also include anionic surfactants can increase the performance of many commonly used types of polymeric soil release agents. . Anionic surfactants impair the ability of certain soil release agents to attach and bind to the hydrophobic surface. These polymeric soil release agents have a nonionic hydrophilic or hydrophobic moiety that interacts with the anionic surfactant.

Improved polymeric soil release agent performance can be obtained by using polyhydroxy fatty acid amides. Anionic surfactant systems, soil release agents that interact with anionic surfactants And (I) a soil release agent (SR) of the detergent composition.
The interaction of the anionic surfactant between A) and the anionic surfactant system is a "control" that measures the SRA deposition of the detergent composition in an aqueous solution in the absence of other detergent components. (B) the same type and amount of the anionic surfactant used in the detergent composition in an aqueous solution,
Soil release to hydrophobic fibers (eg, polyester) in aqueous solution between "SRA / anionic surfactant" test steps combined with anionic surfactant system of the same non-weight ratio SRA versus detergent composition Can be shown by comparing the extent of attachment of the agent (SRA), whereby the decrease in attachment in (B) versus (A) is indicative of an anionic surfactant interaction; (II) Determine whether the detergent composition contains a soil release agent-enhancing amount of polyhydroxyfatty acid amide by the SR of the (B) SRA / anionic surfactant test step.
A adhesion was achieved by combining the same type and concentration of detergent composition polyhydroxyfatty acid amide with a soil release agent and anionic surfactant system corresponding to the SRA / anionic surfactant test step described above (C) " SRA / anionic surfactant
/ PFA test step "can be determined by comparing with the adhesion of the soil release agent, where the test step (B)
On the other hand, the improvement in the adhesion of the soil release agent in the test step (C) indicates that the soil release agent-enhancing amount of polyhydroxy fatty acid amide is contained. For the purposes of the present invention, these tests should be performed at an anionic surfactant concentration in an aqueous solution above the critical micelle concentration (CMC) of the anionic surfactant, preferably at a concentration above about 100 ppm. The concentration of the polymeric soil release agent should be at least 15 ppm. A sample of polyester fabric should be used for the hydrophobic fiber source. The same swatch is immersed in the aqueous solution of each test step at 35 ° C. for 12 minutes, stirred, removed, and analyzed. The degree of adhesion of the polymeric soil release agent can be measured by radiolabeling the soil release agent prior to treatment and then performing a radiochemical analysis by techniques known in the art.

Instead of the radiochemical analysis method described above, the adhesion of the soil release agent to the test step is determined by measuring the ultraviolet (UV) absorbance of the test solution according to techniques well known in the art (i.e., test step A, It can also be measured in B and C). Of the test solution after removal of the hydrophobic textile material
The decrease in UV absorbance corresponds to the increase in SRA attachment. As will be appreciated by those skilled in the art, UV analysis is a test solution containing materials and types of materials that excessively interfere with UV absorption, such as high concentrations of surfactants having aromatic groups (e.g., alkylbenzene sulfonates, etc.). Should not be used.

Thus, "soil release agent enhancing amount" of polyhydroxy fatty acid amide is defined as the amount of surfactant that increases the adhesion of the stain release agent to the hydrophobic fibers as described above, or the detergent of the present invention in the next cleaning operation. Means that can increase the grease / oil cleaning performance of the fabric being washed in the composition.

The amount of polyhydroxy fatty acid amide required to increase adhesion depends on the anionic surfactant selected, the amount of anionic surfactant, the particular soil release agent selected, and the particular polyhydroxy fatty acid amide selected. Varies by. Generally, the composition will comprise from about 0.01% to about 10% by weight of the polymeric soil release agent, typically from about 0.1% to about 5%.
%, And from about 1% to about 50% of an anionic surfactant, more typically from about 4% to about 30%. Such compositions should normally contain at least about 1%, preferably at least about 3%, by weight of the polyhydroxy fatty acid amide, but are not necessarily intended to be limited to this range.

The following description is not intended to limit the invention, but merely to further illustrate the particular aspects of the technology that may be considered by formulators in the manufacture of a wide variety of detergent compositions using polyhydroxy fatty acid amides. Things.

It will be readily appreciated that polyhydroxy fatty acid amides are somewhat unstable under highly basic or highly acidic conditions because of their amide linkages. Although some decomposition is tolerable, it is preferred that these materials not be brought to a pH below about 11, preferably above 10, or below about 3 for too long. The pH of the final product (liquid) is typically between 7.0 and 9.0.

During the production of polyhydroxy fatty acid amides, it is typically required to at least partially neutralize the base catalyst used to form the amide bond. Although any acid may be used for this purpose, detergent formulators will recognize that it is a simple and convenient way to use an acid that supplies other useful and desired anions in the final detergent composition. There will be. For example, citric acid can be used for the purpose of neutralization, and the citrate ion generated (about 1%) is about
It remains with the 40% polyhydroxy fatty acid amide slurry and is sent to the subsequent manufacturing stages of the overall detergent manufacturing process. Acid forms of materials such as oxydisuccinate, nitrilotriacetate, ethylenediaminetetraacetate, tartrate / succinate and the like can be used as well.

Polyhydroxy fatty acid amides derived from coconut alkyl fatty acids (predominantly C ₁₂ -C ₁₄₎ have their tallow alkyl (predominantly C ₁₆ -C ₁₈₎ are more soluble than derivatives. Thus, C ₁₂ -C ₁₄ towards the material is somewhat easier to formulate in the liquid component easily dissolved in cold water washing bath. However, C ₁₆ -C ₁₈ substances are also very useful, especially in an environment using washing water at normal temperature to high temperature. In fact, C
₁₆ -C ₁₈ materials may be better detergent surfactant from C ₁₂ -C ₁₄ derivatives. Therefore, the prescriber
When selecting a particular polyhydroxy fatty acid amide to use in a given formulation, it may be desirable to strike a balance between ease of manufacture and performance.

It will also be appreciated that the solubility of the polyhydroxy fatty acid amide can be increased by having unsaturated fatty acid residues and / or having chain branching. Thus, materials such as polyhydroxy fatty acid amides derived from oleic acid and isostearic acid have
-Higher solubility than alkyl derivatives.

Similarly, the solubility of polyhydroxy fatty acid amides prepared from disaccharides, trisaccharides, etc., is usually higher than the corresponding substances derived from monosaccharides. Such increased solubility can be particularly advantageous when formulating liquid compositions. In addition, polyhydroxy fatty acid amides where the polyhydroxy groups are derived from maltose appear to work particularly well as detergents when used in combination with conventional alkylbenzene sulfonate ("LAS") surfactants. While not intending to be limited by theory, the combined use of LAS and polyhydroxyfatty acid amides derived from polysaccharides such as maltose substantially and significantly reduces interfacial tension in aqueous media, It is believed that the detergency is increased. (The production of polyhydroxyfatty acid amides derived from maltose is described below.) Polyhydroxyfatty acid amides are not only produced from purified sugars, but also hydrolyzed starches, such as corn starch, potato starch or formula. It can also be made from any other convenient plant-derived starch containing the mono-, di-, etc. sugars desired by the individual. This is extremely important from an economic point of view. For example, "high glucose"
Corn syrup, "high maltose" corn syrup and the like can be used conveniently and economically. Lignin removed and hydrolyzed cellulose pulp can also provide a source of polyhydroxy fatty acid amide.

As mentioned above, polyhydroxy fatty acid amides derived from higher sugars such as maltose and lactose are more soluble than those derived from glucose. In addition, more soluble polyhydroxy fatty acid amides can solubilize less soluble ones to varying degrees. Therefore, except for selecting a syrup containing a small amount of maltose (eg, 1% or more)
One would choose to use a feedstock that contains high glucose corn syrup. The resulting mixture of polyhydroxy fatty acids generally exhibits more favorable dissolution properties over a wider range of temperatures and concentrations than polyhydroxy fatty acid amides derived from "pure" glucose. Thus, in addition to any economic benefits of using a sugar mixture over pure sugar reactants, polyhydroxyfatty acid amides prepared from mixed sugars have very substantial benefits in terms of performance and / or ease of formulation. provide. However, in some cases, some degreasing performance (dishwashing) is lost at fatty acid maltamide levels above about 25%, and lathering is lost above about 33% (this percentage is due to the maltamide-derived polyhydroxy in the mixture). Fatty acid amide to percent of glucose derived polyhydroxy fatty acid amide.) This can vary somewhat with the length of the fatty acid residues. Typically, the formulator who decides to use such a mixture is a monosaccharide (eg, glucose) versus a disaccharide or higher saccharide (eg, maltose).
Can be found to be advantageous to select polyhydroxy fatty acid amide mixtures having a ratio of from about 4: 1 to about 99: 1.

The production of polyhydroxy fatty acid amide from a fatty acid ester and an N-alkyl polyol is carried out in an alcohol solvent by about
It can be carried out at a temperature of from 30C to 90C, preferably from about 50C to 80C. For example, for liquid detergent formulators, the above steps can be performed in 1,2-propylene glycol solvent since it is not necessary to completely remove the glycol solvent from the reaction product prior to use in the finished detergent formulation. It may be convenient to do so. Similarly, the formulator of a solid, typically granular detergent composition, for example, may have ethoxylated (EO)
3-8) It is convenient to carry out the process at 30 ° C. to 90 ° C. in a solvent containing an ethoxylated alcohol such as a C ₁₂ -C ₁₄ alcohol, eg a commercial product such as NEODOL 23EO6.5 (Shell). You can find things. If such ethoxylates are used, it is preferred that they contain no substantial amount of non-ethoxylated alcohol and no substantial amount of mono-ethoxylated alcohol (designated "T"). .

Although the preparation of the polyhydroxy fatty acid amide itself does not form part of the present invention, the formulator may also focus on other synthetic methods of the polyhydroxy fatty acid amide described below.

Typically, the reaction order on an industrial scale to produce the preferred acyclic polyhydroxyfatty acid amide is as follows: Step 1 From the desired saccharide or saccharide mixture, the formation of an N-alkylamine and an adduct of this saccharide with the N-alkylamine After preparing the alkylpolyhydroxyamine derivative, reacting it with hydrogen in the presence of a catalyst, then step 2 comprising reacting said polyhydroxyamine, preferably with a fatty acid ester, to form an amide bond. I have. Stage 2 of the reaction sequence
The various N-alkyl polyhydroxyamines used in can be prepared by various methods disclosed in the art, but the following methods are advantageous, using economical sugar syrups as raw materials. I have. When using such syrup ingredients, it should be understood that for best results, the manufacturer should choose a syrup that is very bright or preferably nearly colorless ("clear and colorless"). It is.

Preparation of N-Alkyl Polyhydroxyamines from Vegetable Sugar Syrups I. Formation of Adducts The following is a description of an approximately 55% glucose solution with less than 1 Gardner color (corn syrup, approximately 23%).
1 g glucose, about 1.28 mol) about 420 g about 50% aqueous methylamine (methylamine 59.5 g, 1.92 mol) solution about 119 g
This is a standard method characterized by reacting Methylamine (MMA) solution is replaced with N ₂ shield, about 1
Cool to 0 ° C or less. Corn syrup at a temperature of about 10 ° C. to 20 ° C. was replaced with N ₂ shield. Corn syrup,
Add slowly to the MMA solution at the prescribed reaction temperatures described below. The Gardner color is measured at a given time expressed in minutes.

As can be seen from the above data, when the temperature exceeds about 30 ° C, the Gardner color of the additional product is quite bad,
At about 50 ° C., the time for the Gardner color of the adduct to fall below 7 is only about 30 minutes. For longer reaction times and / or longer hold times, the temperature should be less than about 20 ° C. To obtain good color glucamine, the Gardner color is less than about 7, preferably less than about 4.

When forming adducts at low temperatures, the time to reach a substantial equilibrium concentration of the adduct is reduced by increasing the amine to sugar ratio. At a 1.5: 1 molar amine to sugar ratio, the reaction temperature reaches equilibrium at about 30 ° C. in about 2 hours. At a ratio of 1.2: 1 mol under the same conditions, the time is at least about 3 hours. To obtain good color, the combination of amine: sugar ratio, reaction temperature and reaction time is selected to achieve a substantial equilibrium conversion, for example, greater than about 90% for sugar. , Preferably about
It is selected to be greater than 95%, more preferably greater than about 99%, and the color of the adduct is less than about 7, preferably less than about 4, more preferably less than about 1.

Using a corn syrup having a reaction temperature of less than about 20 ° C. and the above method and various Gardner colors as described above (after substantially equilibrating in at least about 2 hours)
The color of the MMA adduct is as described above.

As can be seen from the above table, the starting sugar material must be nearly colorless to obtain a consistently acceptable adduct. When the sugar has a Gardner color of about 1, the adduct may or may not be acceptable.
When the Gardner color is greater than one, the resulting adduct is unacceptable. The better the initial color of the sugar, the better the color of the adduct.

II. Hydrogen Reaction The adduct obtained from the above reaction having a Gardner color of 1 or less is hydrogenated by the following procedure.

Increase to 50 ° C. The pressure is then increased to about 1600 psig and the temperature is held at about 50-55 ° C for about 3 hours. The product is now about 95% hydrogenated. The temperature is then raised to about 85 ° C. for about 30 minutes, the reaction mixture is decanted and the catalyst is filtered off. water and
The product after distilling off the MMA is a white powder of about 95% N-methylglucamine.

The above procedure is repeated with about 23.1 g of Raney nickel catalyst, except for the following changes. After washing the catalyst three times and putting the catalyst in the reactor,
Was replaced twice with 0PsigH _2, emits a reactor 2 hours pressurized to 1600 psig with H _2, the pressure at 1 hr, 1600 psig and reactor
And repressurized. The adduct was then fed to the reactor at 200 psig and 20 ° C. and the reactor was
Replace with ₂ etc.

The product in each case is greater than about 95% N-methylglucamine, with about 10 ppm Ni to glucamine.
And the color of the solution is less than about 2 in Gardner color.

Crude N-methylglucamine has color stability for short exposures of about 140 ° C.

Low sugar content (less than about 5%, preferably less than about 1%)
And good color (less than about 7, preferably less than about 4,
More preferably, less than about 1 Gardner), it is important to obtain good adducts.

In another reaction, about 159 g of about 50% methylamine
It was dissolved in water, which was replaced with N ₂ at about 10 to 20 ° C., starting from those shielding to prepare an adduct. About 330 g of about 70% corn syrup (almost colorless and transparent) is degassed with N ₂ at about 50 ° C. and slowly added to the methylamine solution at a temperature below about 20 ° C. The solution is mixed for about 30 minutes to give an adduct of about 95% of a very bright yellow solution.

Example 14 The preparation of tallow (cured) fatty acid amide for use in the detergent composition according to the present invention is as follows.

Step 1 Reactants: maltose monohydrate (Aldrich, lot number 01318KW), methylamine (40% by weight aqueous solution) (Aldrich, lot number 03325TM), Raney nickel, 50% slurry (UAD52-73D, Aldrich, lot number 1)
2921LW).

Add reactants to glass liner (250 g maltol, 42
8 g methylamine solution, 100 g catalyst slurry-50 g Raney nickel), placed in a 3 liter shaking autoclave,
This is nitrogen (3 × 500psig) and hydrogen (2 × 500psig)
In replacing, under an atmosphere of H ₂ at room temperature and shaken over the weekend at a temperature of 28 ° C. to 50 ° C.. The crude reaction mixture is vacuum filtered twice through a glass microfiber filter equipped with a silica gel stopper. Concentrate the filtrate to a viscous material. After dissolving this material in methanol, the last traces of water are boiled off by removing the methanol / water on a rotary evaporator. The final drying is performed under high vacuum. The crude product is dissolved in refluxing methanol, filtered, recrystallized on cooling, filtered and the filter cake is dried at 35 ° C. under vacuum. This is Sample No. 1. The filtrate is concentrated until a precipitate begins to form and stored in the refrigerator overnight. The solid is filtered and dried under vacuum. This is Sample No. 2. The filtrate is again concentrated to half the volume and recrystallized. Very little precipitate forms. A small amount of ethanol is added and the solution is left in the refrigerator over the end. Filter the solid material and dry under vacuum. The combined solid consists of N-methylmaltoamine, which is used in step 2 of the total synthesis.

Step 2 Reactants: N-methylmaltoamine (from step 1), cured tallow methyl ester, sodium methoxide (25% methanol solution), anhydrous methanol (solvent), molar ratio 1: 1 = amine: ester, initial catalyst Concentration 10
Mol% (w / r maltoamine), rising to 20 mol%, solvent level 50% (weight).

In a sealed bottle, 20.36 g of tallow methyl ester is heated to its melting point (water bath) and placed in a three-necked round bottom flask equipped with a mechanical stirrer. Heat the flask to about 70 ° C,
Prevents the ester from solidifying. Separately, 25.0 g of N-methylmaltoamine are combined with 45.36 g of methanol and the resulting slurry is added to the tallow ester with thorough mixing. 1.51 g of 25% sodium methoxide dissolved in methanol is added. After 4 hours, the reaction mixture did not become clear, so an additional 10 mole% (20 mole% total) of the catalyst was added and the reaction was continued overnight (about 68 ° C), whereupon the mixture became clear. Next, distillation is performed by modifying the reaction flask. Increase temperature to 110 ° C. 6 distillation at atmospheric pressure

The ether is distilled off on a rotary evaporator and the product is stored in an oven overnight and ground to a powder. Residual N-methylmaltoamine is removed from the product using silica gel. A slurry of silica gel in 100% methanol is placed in a funnel and washed several times with 100% methanol. Product (20g
/ 100% methanol (100 g) on silica gel and elute several times using vacuum and several methanol washes. The combined eluate is evaporated to dryness (rotary evaporator). The remaining tallow ester is removed by triturating overnight with ethyl acetate and then filtered. Vacuum dry the filter cake overnight. The product is a tallow alkyl N-methylmaltoamide.

In another scheme, step 1 of the reaction sequence comprises glucose or a mixture of glucose and typically 5
% Of maltose in a commercially available corn syrup. The resulting polyhydroxyfatty acid amines and mixtures can be used in any of the detergent compositions of the present invention.

In yet another scheme, Step 2 of the reaction sequence described above.
Can be carried out in 1,2-propylene glycol or neodol. At the discretion of the formulator, it is not necessary to remove propylene glycol or neodol from the reaction product before formulating the detergent composition with the reaction product. Also, if desired by the formulator, the methoxide catalyst can be neutralized with citric acid to provide sodium citrate, which can remain in the polyhydroxy fatty acid amide.

Depending on the wishes of the formulator, the compositions of the present invention may contain some foam control agents. Typically, no high-foaming agents are used in dishwashing, as no suds suppressors are used. For laundering textiles in a top-loading washing machine, it is desirable to have some foam control, and the front-loading (fr)
In on-loading washing machines, significant levels of suds suppressors may be preferred. A wide variety of suds suppressors are known in the art and can be routinely selected for use in the present invention. In fact, the choice of suds suppressor or suds suppressor mixture for any particular detergent composition will not only depend on the presence and amount of the polyhydroxy fatty acid amide used in the present invention, but will also be included in the formulation. It also depends on the surfactant used. However,
For use with polyhydroxy fatty acid amides, various silicone-based suds suppressors are more efficient (i.e., can be used at lower concentrations) than various other suds suppressors. Silicone foam suppressors X2-3419 and Q2
Particularly useful is a silicone suds suppressor sold as -3302 (Dow Corning).

Formulators of fabric detergent compositions that can conveniently include a soil release agent have a wide variety of known materials to choose from (e.g., U.S. Patent Nos. 3,962,152 and 4,116,885).
Nos. 4,238,531, 4,702,857, 4,721,580 and 4,877,896. ) Other soil release agents which can be used in the present invention, C ₁ -C ₄ polyethoxy units sources having alkoxy-terminated (e.g., CH ₃ [O
CH ₂ CH ₂ ] ₁₆ OH), terephthaloyl unit source (eg, dimethyl terephthalate), poly (oxyethylene) oxy unit (eg, polyethylene glycol 1500), oxyiso-propyleneoxy unit source (eg, 1,2-propylene glycol) And a non-ionic oligomeric esterification product of a reaction mixture comprising a source of oxyethyleneoxy units (eg, ethylene glycol), especially where the molar ratio of oxyethyleneoxy units: propyleneoxy units is at least about 0.5: 1. There are things. Such non-ionic soil release agents have the general formula Wherein R ¹ is lower (ie, C ₁ -C ₄ ) alkyl, especially methyl, x and y are each an integer from about 6 to about 100, and m is an integer from about 0.75 to about 30 , N is about 0.25
To about 20 represents an integer of, R ² is an oxyethylene: at least about 0.5 molar ratio of oxyisopropylene propyleneoxy: 1
Which is a mixture of H and CH ₃ for

Another preferred class of soil release agents useful in the present invention is of the general anionic type described in U.S. Pat. No. 4,877,896, but these release agents are substantially of the HOROH type ( Provided that R is a propylene or higher alkyl) monomer. For example, the soil release agent described in U.S. Pat.No. 4,877,896 is the reaction product of dimethyl terephthalate, ethylene glycol, 1,2-propylene glycol and 3-sodium sulfobenzoic acid, but these additional soil release The agent is, for example, the reaction product of dimethyl terephthalate, ethylene glycol, 5-sodium sulfoisophthalate and 3-sodium sulfobenzoic acid. Such compounds are preferred for use in granular laundry detergents.

The formulator advantageously includes the non-perborate bleach in a particularly strong granular laundry detergent. Various peroxygen bleaches are commercially available and can be used in the present invention, of which percarbonate is convenient and economical. Accordingly, the compositions of the present invention may contain solid bleach, usually at a level of 3% to 20%, more preferably 5% to 18%, most preferably 8% to 15% by weight of the composition. In the form of a sodium salt.

Sodium percarbonate is an adduct having the formula corresponding to 2Na ₂ CO ₃ .3H ₂ O ₂ and is commercially available as a crystalline solid. Most commercially available materials contain low levels of heavy sequestering agents incorporated during the manufacturing process, such as EDTA, 1-hydroxyethylidene, 1,1-diphosphonic acid (HEDP) or amino-phosphate. For use in the present invention, the percarbonate can be incorporated into the detergent composition without additional protection, but the preferred embodiment of the present invention utilizes a stable form of the material (FMC). A wide variety of coatings can be used, but the most economical is
SiO _2: Na ₂ O ratio of 1.6: 1 to 2.8: 1, preferably 2.0: a 1 sodium silicate, applied as an aqueous solution, dried, the weight of the silicate solid percarbonates Yields concentrations of 2% to 10% (usually 3% to 5%). Magnesium silicate can also be used, and a chelating agent such as one of the above can be included in the coating.

The particle size range of the crystalline percarbonate is 350 μm to 450 μm, with an average value of about 400 μm. Upon coating, the grain size of the crystals is in the range of 400-600 μm.

The heavy metals contained in the sodium carbonate used to make the percarbonate can be adjusted by including a sequestering agent in the reaction mixture, but the percarbonate is still present as an impurity in other components of the product. It must be protected from the heavy metals it contains. The total concentration of iron, copper and manganese ions in the product should not exceed 25 ppm,
It should preferably be less than 20 ppm so as not to unacceptably adversely affect the stability of the percarbonate.

The new concentrated laundry detergent particles are as follows.

Example 15 ¹ laminated silicate builders are known in the art. Preferred is laminated sodium silicate2, for example, US Pat. No. 4,664,859 issued to HP Rieck on May 12, 1987, the contents of which are incorporated herein by reference. See the Laminated Sodium Silicate Builder described in the above. A suitable laminated silicate builder is commercially available from Hoechst as SKS-6.

Highly preferred granules of the type described above have an active enzyme of about 0.00
Those containing from 01% to about 2% by weight and at least about 1% by weight of the polyhydroxyfatty acid amide, most preferably those in which the anionic surfactant is not an alkylbenzene sulfonate surfactant.

The following description relates to the preparation of a preferred liquid laundry detergent according to the invention. It will be appreciated that the stability of the enzyme in such compositions is significantly lower than that of granular detergents. However, by using typical enzyme stabilizers such as formate and boric acid, lipase and cellulase enzymes can be prevented from being degraded by protease enzymes. However, lipase stability is still relatively poor in the presence of alkylbenzene sulfonate ("LAS") detergents. It is clear that LAS partially denatures lipase, and denatured lipase appears to be susceptible to protease attack.

In view of the foregoing considerations that liquid compositions can be particularly problematic as described above, it is an adventure to provide a liquid detergent composition that includes lipase, protease and cellulase enzymes together. It is particularly difficult to provide these trienzyme systems with an effective formulation of a detergent surfactant in a stable liquid detergent. Moreover, it is difficult to stably incorporate peroxidase and / or amylase enzymes into such compositions.

Various mixtures of lipases, proteases, cellulases, amylases and peroxidases are fairly stable in the presence of certain non-alkylbenzenesulfonate surfactant systems, formulating even effective heavy solid and liquid detergents I found that I could do that. Indeed, the formulation of a stable, liquid, enzyme-containing detergent composition is extremely advantageous and is a preferred embodiment provided by the techniques of the present invention.

In particular, prior art liquid detergent compositions typically contain LAS

It will be appreciated that the LAS may be present in small amounts but the stability of the enzyme is thereby reduced. Thus, the liquid composition is substantially free of LAS (ie, less than about 10%, preferably less than about 5%).

When using 85 g of detergent in a G brand washing machine at 30 ° C., 40 ° C., 60 ° C. and 90 ° C. cycle, it shows excellent solubility, excellent performance and excellent foam control action.

Example 20 In any of the above examples, the fatty acid glucamide surfactant can be replaced by an equivalent amount of a maltamide surfactant or a glucamide / maltoamide mixture derived from a plant sugar source. In these compositions, the use of ethanolamide will aid in the low temperature stability of the finished formulation. In addition, the use of a sulfobetaine (also known as "sultaine") surfactant results in excellent lathering.

The following examples illustrate other liquid compositions that are particularly suitable for "light" applications, such as dishwashing.

Examples 21A-D If a particularly good foaming composition is desired (for example,
Dishwashing), since there is possible to suppress the C ₁₄ or more fatty acids are foaming, these fatty acids are preferably less than about 5%, more preferably less than about 2%, and most preferably substantially free at all. Therefore, the formulator of the high foaming composition may not introduce such a suds suppressing amount of fatty acid into the high foaming composition comprising polyhydroxy fatty acid amide and / or reduce the C ₁₄ or higher fatty acids during storage of the finished composition. It is desirable not to form any. One simple means is to prepare the polyhydroxy fatty acid amides of the present invention with reference to C ₁₂ ester reactants. Fortunately, the use of an amine oxide or sulfobetaine surfactant can reduce some of the negative foaming effects caused by this fatty acid.

A relatively high concentration of anionic optical brightener (eg,
Formulators who wish to add to liquid detergents containing anionic or polyanionic substituents, such as (10% or more) polycarbonate builder, may premix the brightener with water and polyhydroxyfatty acid amide and then add the premix. It can be found useful to add to the final composition.

Polyglutamic or polyaspartic acid detergent,
It can be used effectively with detergents containing zeolite. AE fluids or flakes and DC-544 (Dow Corning) are other examples of useful foam control agents of the present invention.

If a person skilled in the chemical technical field prepares a polyhydroxyfatty acid amide using a disaccharide or higher saccharide such as maltose, the polyhydroxyfatty acid amide, in which the linear substituent Z has a polyhydroxy ring structure, It will be understood that this results in what is "capped". Such materials are not intended at all in the present invention and do not depart from the spirit and scope of the disclosed and claimed invention.
