Definitions
- enzymes are biological materials they are subject to denaturation and deactivation, especially after prolonged contact with other ingredients present in fully formulated detergent compositions. Thus, a freshly formulated detergent composition containing enzymes will often exhibit substantially higher cleaning performance than will older product which has been warehoused or stored on the shelf. Shelf-stability of enzyme- containing detergent compositions, especially liquid detergents, has been of considerable concern to formulators, and a variety of enzyme stabilizers have been devised. For example, various boron compounds, formate salts, ethanolamines, and/or various short chain fatty acids are commonly added to detergent compositions to provide enzyme stability. Such stabilizers are often used in liquid detergent compositions containing enzymes. Moreover, enzymes are relatively expensive, and their inclusion in detergent compositions represents an added cost to the formulator and, ultimately, to the user. Accordingly, it would be advantageous if enzyme performance were improved by less

- the choice of brightener for use in detergent compositions will depend upon a number of factors, such as the type of detergent, the nature of other components present in the detergent composition, the temperatures of wash water, the degree of agitation, and the ratio of the material washed to tub size.
- the brightener selection is also dependent upon the type of material to be cleaned, e.g., cottons, synthetics, etc. Since most laundry detergent products are used to clean a variety of fabrics, the detergent compositions should contain a mixture of brighteners which will be effective for a variety of fabrics. It is of course necessary that the individual components of such a brightener mixture be compatible.

- Suds Suppressors Compounds known, or which become known, for reducing or suppressing the formation of suds can be incorporated into the compositions of the present invention.
- the incorporation of such materials, hereinafter “suds suppressors,” can be desirable because the polyhydroxy fatty acid amide surfactants hereof can increase suds stability of the detergent compositions. Suds suppression can be of particular importance when the detergent compositions include a relatively high sudsing surfactant in combination with the polyhydroxy fatty acid amide surfactant. Suds suppression is particularly desirable for compositions intended for use in front loading automatic washing machines. These machines are typically characterized by having drums, for containing the laundry and wash water, which have a horizontal axis and rotary action about the axis. This type of agitation can result in high suds formation and, consequently, in reduced cleaning performance.
- the use of suds suppressors can also be of particular importance under hot water washing conditions and under high surfactant concentration conditions.
- the detergent compositions may also contain non-surfactant suds suppressors.
- non-surfactant suds suppressors include, for example, list: high molecular weight hydrocarbons such as paraffin, fatty acid esters (e.g., fatty acid triglycerides), fatty acid esters of monovalent alcohols, aliphatic C 18 -C 40 ketones (e.g. stearone), etc.
- suds inhibitors include N-alkylated amino triazines such as tri- to hexa-alkylmelamines or di- to tetra-alkyldiamine chlortriazines formed as products of cyanuric chloride with two or three moles of a primary or secondary amine containing 1 to 24 carbon atoms, propylene oxide, and monostearyl phosphates such as monostearyl alcohol phosphate ester and monostearyl di-alkali metal (e.g. K, Na, and Li) phosphates and phosphate esters.
- the hydrocarbons such as paraffin and haloparaffin can be utilized in liquid form.
- the liquid hydrocarbons will be liquid at room temperature and atmospheric pressure, and will have a pour point in the range of about -40 * C and about 5 * C, and a minimum boiling point not less than about IIO'C (atmospheric pressure). It is also known to utilize waxy hydrocarbons, preferrably having a melting point below about lOO'C.
- the hydrocarbons constitute a preferred category of suds suppressor for detergent compositions. Hydrocarbon suds suppressors are described, for example, in U.S. Patent 4,265,779, issued May 5, 1981 to Gandolfo, et al, incorporated herein by reference.
- Non-surfactant suds comprises silicone suds suppressors.
- This category includes the use of polyorganosiloxane oils, such as polydi ethylsiloxane, dispersions or emulsions of polyorganosiloxane oils or resins, and combina ⁇ tions of polyorganosiloxane with silica particles wherein the polyorganosiloxane is chemisorbed of fused onto the silica.
- Silicone suds suppressors are well known in the art and are, for example, disclosed in U.S. Patent 4,265,779, issued May 5, 1981 to Gandolfo et al and European Patent Application No. 89307851.9, published February 7, 1990, by Starch, M. S., both incorporated herein by reference.

- suds should not form to the extent that they overflow the washing machine.
- Suds suppressors when utilized, are preferably present in a "suds suppressing amount.”
- Suds suppressing amount is meant that the formulator of the composition can select an amount of this suds controlling agent that will sufficiently control the suds to result in a low-sudsing laundry detergent for use in automatic laundry washing machines. The amount of suds control will vary with the detergent surfact ⁇ ants selected.
- a sufficient amount of suds suppressor should be incorporated in low sudsing detergent compositions so that the suds that form during the wash cycle of the automatic washing machine (i.e., upon agitation of the detergent in aqueous solution under the intended wash temperature and concentration conditions) do not exceed about 75% of the void volume of washing machine's containment drum, preferably the suds do not exceed about 50% of said void volume, wherein the void volume is determined as the difference between total volume of the containment drum and the volume of the water plus the laundry.
- the compositions hereof will generally comprise from 0% to about 5% of suds suppressor.
- monocarboxylic fatty acids, and salts thereof When utilized as suds suppressors, monocarboxylic fatty acids, and salts thereof, will be present typically in amounts up to about 5%, by weight, of the detergent composition. Preferably, from about 0.5% to about 3% of fatty onocarboxylate suds suppressor is utilized. Silicone suds suppressors are typically utilized in amounts up to about 2.0%, by weight, of the detergent composition, although higher amounts may be used. This upper limit is practical in nature, due primarly to concern with keeping costs minimized and effectiveness of lower amounts for effectively controlling sudsing. Preferably from about 0.01% to about 1% of silicone suds suppressor is used, more preferably from about 0.25% to about 0.5%.
- these weight percentage values include any silica that may be utilized in combination with polyorganosiloxane, as well as any adjunct materials that may be utilized.
- Monostearyl phosphates are generally utilized in amounts ranging from about 0.1% to about 2%, by weight, of the composition.

- the remaining dry ingredients are admixed in granular or powder form with the spray dryed granule in a rotary mixing drum, and the liquid ingredients (nonionic surfactant and perfume) sprayed on.
- the following relates to the preparation of a preferred liquid heavy duty laundry detergent according to this invention.
- the stability of enzymes in such compositions is considerably less than in granular detergents.
- typical enzyme st ⁇ .bilizers such as formate and boric acid
- lipase and cellulase enzymes can be protected from degradation by protease enzymes.
- lipase stability is still relatively poor in the presence of alkylbenzene sulfonate (“LAS”) surfactants.
- LAS alkylbenzene sulfonate
- liquid detergent compositions containing lipase, protease and cellulase enzymes, together. It is particu ⁇ larly challenging to provide such tertiary enzyme systems in stable liquid detergents together with an effective blend of detersive surfactants. Additionally, it is difficult to incorporate peroxidase and/or amylase enzymes stably in such compositions.
- the liquid detergents herein preferably comprise binary mixtures of the AES and polyhydroxy fatty acid amides of the type disclosed herein. While minimal amounts of LAS can be present, it will be appreciated that the stability of the enzymes will be lessened thereby. Accordingly, it is preferred that the liquid compositions be substantially free (i.e., contain less than about 10%, preferably less than about 5%, more preferably less than about 1%, most preferably 0%) of LAS.
- the present invention provides a liquid detergent composition comprising:
- R 2 is C 5 -C 31 hydrocarbyl

Also, see the Upases described in EP A 0399681, published November 28, 1990, EP A 0218272, published April 15, 1987 and PCT/DK 88/00177, published May 18, 1989, all incorporated herein by reference.

- Brightener 36 is commercially available as TIN0PAL TAS 36.
- the brightener is added to the composition as a separately prepared pre-mix of brightener (4.5%), monoethanolamine (60%) and water (35.5%).
- the polyhydroxy fatty acid amides are, by virtue of their amide bond, subject to some instability under highly basic or highly acidic conditions. While some decomposition can be tolerated, it is preferred that these materials not be subjected to pH's above about 11, preferably 10, nor below about 3 for unduly extended periods. Final product pH (liquids) is typically 7.0-9.0. During the manufacture of the polyhydroxy fatty acid amides it will typically be necessary to at least partially neutralize the base catalyst used to form the amide bond. While any acid can be used for this purpose, the detergent formulator will recognize that it is a simple and convenient matter to use an acid which provides an anion that is otherwise useful and desirable in the finished detergent composition.
- citric acid can be used for purposes of neutralization and the resulting citrate ion (ca. 1%) be allowed to remain with a ca. 40% polyhydroxy fatty acid amide slurry and be pumped into the later manufacturing stages of the overall detergent-manufacturing process.
- the acid forms of materials such as oxydisuccinate, nitrilotriacetate, ethylenediaminetetraacetate, tartrate/succinate, and the like, can be used similarly.
- the polyhydroxy fatty acid amides derived from coconut alkyl fatty acids are more soluble than their tallow alkyl (predominantly C 16 -C 18 ) counterparts.
- the C 12 -C 14 materials are somewhat easier to formulate in liquid compositions, and are more soluble in cool-water laundering baths.
- the C 16 -C 18 materials are also quite useful, especially under circumstances where warm-to-hot wash water is used. Indeed, the C 16 -C 18 materials may be better detersive surfactants than their C 12 -C 14 counterparts. Accordingly, the formulator may wish to balance ease-of-manufacture vs. performance when selecting a particular polyhydroxy fatty acid amide for use in a given formulation.
- solubility of the polyhydroxy fatty acid amides can be increased by having points of unsaturation and/or chain branching in the fatty acid moiety.
- materials such as the polyhydroxy fatty acid amides derived from oleic acid and iso-stearic acid are more soluble than their n-alkyl counterparts.
- polyhydroxy fatty acid amides prepared from disaccharides, trisaccharides, etc. will ordinarily be greater than the solubility of their monosaccharide-derived counterpart materials. This higher solubility can be of particu ⁇ lar assistance when formulating liquid compositions.
- polyhydroxy fatty acid amides wherein the polyhydroxy group is derived from maltose appear to function especially well as deter ⁇ gents when used in combination with conventional alkylbenzene sulfonate ("LAS") surfactants.
- LAS alkylbenzene sulfonate
- polyhydroxy fatty acid amides derived from the higher saccharides such as maltose, lactose, etc.
- the more soluble polyhydroxy fatty acid amides can help solubilize their less soluble counterparts, to varying degrees.
- the formulator may elect to use a raw material comprising a high glucose corn syrup, for example, but to select a syrup which contains a modicum of maltose (e.g., 1% or more).
- the resulting mixture of polyhydroxy fatty acids will, in general, exhibit more preferred solubility properties over a broader range of temperatures and concentrations than would a "pure" glucose- derived polyhydroxy fatty acid amide.
- the formulator electing to use such mixtures may find it advantageous to select polyhydroxy fatty acid amide mixtures which contain ratios of monosaccharides (e.g., glucose) to di- and higher saccharides (e.g., maltose) from about 4:1 to about 99:1.
- monosaccharides e.g., glucose
- di- and higher saccharides e.g., maltose
- the formulator of, for example, solid, typically granular, detergent compositions may find it convenient to run the process at 30'C-90 ⁇ C in solvents which comprise ethoxylated alcohols, such as the ethoxylated (EO 3-8) C 12 -C 14 alcohols, such as those available as NEODOL 23 E06.5 (Shell).
- ethoxylated alcohols such as the ethoxylated (EO 3-8) C 12 -C 14 alcohols, such as those available as NEODOL 23 E06.5 (Shell).
- EO 3-8 ethoxylated (EO 3-8) C 12 -C 14 alcohols, such as those available as NEODOL 23 E06.5 (Shell).
- the industrial scale reaction sequence for prepar- ing the preferred acyclic polyhydroxy fatty acid amides will comprise: Step 1 - preparing the N-alkyl polyhydroxy amine derivative from the desired sugar or sugar mixture by formation of an adduct of the N-alkyl amine and the sugar, followed by reaction with hydrogen in the presence of a catalyst; followed by Step 2 - reacting the aforesaid polyhydroxy amine with, preferably, a fatty ester to form an amide bond.
- Step 2 of the reaction sequence can be prepared by various art-disclosed processes, the following process is convenient and makes use of economical sugar syrup as the raw material. It is to be understood that, for best results when using such syrup raw materials, the manufacturer should select syrups that are quite light in color or, preferably, nearly colorless ("water-white").
- the Gardner Color for the adduct is much worse as the temperature is raised above about 30*C and at about 50'C, the time that the adduct has a Gardner Color below 7 is only about 30 minutes.
- the temperature should be less than about 20 ⁇ C.
- the Gardner Color should be less than about 7, and preferably less than about 4 for good color glucamine.
- the combination of amine:sugar ratio; reaction temperature; and reaction time is selected to achieve substantially equilibrium conversion, e.g., more than about 90%, preferably more than about 95%, even more preferably more than about 99%, based upon the sugar, and a color that is less than about 7, preferably less than about 4, more preferably less than about 1, for the adduct.
- the MMA adduct color (after substantial equilibrium is reached in at least about two hours) is as indicated.
- Adduct 3 4/5 7/8 7/8 1 2 1 Adduct 3 4/5 7/8 7/8 1 2 1
- the starting sugar material must be very near colorless in order to consistently have adduct that is acceptable.
- the adduct is sometimes acceptable and sometimes not accept ⁇ able.
- the Gardner Color is above 1 the resulting adduct is unacceptable. The better the initial color of the sugar, the better is the color of the adduct.
- the above procedure is repeated with about 23.1 g of Raney Ni catalyst with the following changes.
- the catalyst is washed three times and the reactor, with the catalyst in the reactor, is purged twice with 200 psig H 2 and the reactor is pressurized with H 2 at 1600 psig for two hours, the pressure is released at one hour and the reactor is repressurized to 1600 psig.
- the adduct is then pumped into the reactor which is at 200 psig and 20 ⁇ C, and the reactor is purged with 200 psig H 2 , etc., as above.
- the resulting product in each case is greater than about 95% N-methyl glucamine; has less than about 10 ppm Ni based upon the glucamine; and has a solution color of less than about Gardner 2.
- the crude N-methyl glucamine is color stable to about 140 * C for a short exposure time.
- adduct is prepared starting with about 159 g of about 50% methylamine in water, which is purged and shielded with N 2 at about 10-20 * C. About 330 g of about 70% corn syrup (near water-white) is degassed with N 2 at about 50 * C and is added slowly to the methylamine solution at a temperature of less than about 20 * C. The solution is mixed for about 30 minutes to give about 95% adduct that is a very light yellow solution.
- About 190 g of adduct in water and about 9 g of United Catalyst G49B Ni catalyst are added to a 200 ml autoclave and purged three times with H 2 at about 20 * C.
- the H 2 pressure is raised to about 200 psi and the temperature is raised to about 50"C.
- the pressure is raised to 250 psi and the temperature is held at about 50-55 * C for about three hours.
- the product, which is about 95% hydrogenated at this point, is then raised to a temperature of about 85'C for about 30 minutes and the product, after removal of water and evaporation, is about 95% N-methyl glucamine, a white powder.
- Ni content in the glucamine is about 100 ppm as compared to the less than 10 ppm in the previous reaction.
- Adduct for use in making glucamine is prepared by combining about 420 g of about 55% glucose (corn syrup) solution (231 g glucose; 1.28 moles) (the solution is made using 99DE corn syrup from CarGill, the solution having a color less than Gardner 1) and about 119 g of 50% methylamine (59.5 g MMA; 1.92 moles) (from Air Products).
- the reaction procedure is as follows:
- the glucamine adduct hydrogen reactions are as follows:
- Step 1 - Reactants Maltose monohydrate (Aldrich, lot 01318KW); methylamine (40 wt% in water) (Aldrich, lot 03325TM); Raney nickel, 50% slurry (UAD 52-73D, Aldrich, lot 12921LW).

- the crude reaction mixture is vacuum filtered 2X through a glass microfiber filter with a silica gel plug.
- the filtrate is concentrated to a viscous material.
- the final traces of water are azetroped off by dissolving the material in methanol and then removing the methanol/water on a rotary evaporator.
- Step 2 Reactants: N-methyl maltamine (from Step 1); hardened tallow methyl esters; sodium methoxide (25% in methanol); absolute methanol (solvent); mole ratio 1:1 amine:ester; initial catalyst level 10 mole % (w/r maltamine), raised to 20 mole %; solvent level 50% (wt.).
- 20.36 g of the tallow methyl ester is heated to its melting point (water bath) and loaded into a 250 ml 3-neck round-bottom flask with mechanical stirring. The flask is heated to ca. 70'C to prevent the ester from solidifying.
- the product is allowed to remain in the reaction flask at 110'C (external temperature) for 60 minutes.
- the product is scraped from the flask and triturated in ethyl ether over a weekend.
- Ether is removed on a rotary evaporator and the product is stored in an oven overnight, and ground to a powder. Any remaining N-methyl maltamine is removed from the product using silica gel.
- a silica gel slurry in 100% methanol is loaded into a funnel and washed several times with 100% methanol.
- a concentrated sample of the product (20 g in 100 ml of 100% methanol) is loaded onto the silica gel and eluted several times using vacuum and several methanol washes.
- the collected eluant is evaporated to dryness (rotary evaporator). Any remaining tallow ester is removed by trituration in ethyl acetate overnight, followed by filtration. The filter cake is vacuum dried overnight. The product is the tallowalkyl N-methyl maltamide.
- Step 1 of the foregoing reaction sequence can be conducted using commercial corn syrup comprising glucose or mixtures of glucose and, typically, 5%, or higher, maltose.
- the resulting polyhydroxy fatty acid amides and mixtures can be used in any of the detergent compositions herein.
- Step 2 of the foregoing reaction sequence can be carried out in 1,2-propylene glycol or NEODOL.
- the propylene glycol or NEODOL need not be removed from the reaction product prior to its use to formulate detergent compositions.
- the methoxide catalyst can be neutralized by citric acid to provide sodium citrate, which can remain in the polyhydroxy fatty acid amide.
- the compositions herein can contain more or less of various suds control agents.
- various suds control agents For dishwashing high sudsing is desirable so no suds control agent will be used.
- a wide variety of suds control agents are known in the art and can be routinely selected for use herein. Indeed, the selection of suds control agent, or mixtures of suds control agents, for any specific detergent composition will depend not only on the presence and amount of polyhydroxy fatty acid amide used therein, but also on the other surfactants present in the formulation.
- silicone-based suds control agents of various types are more efficient (i.e., lower levels can be used) than various other types of suds control agents.
- the silicone suds control agents available as X2-3419 and Q2-3302 (Dow Corning) are particularly useful herein.
- Additional soil release materials useful herein include the nonionic oligomeric esterification product of a reaction mixture comprising a source of C x -C 4 al oxy-terminated polyethoxy units (e.g., CH 3 [0CH 2 CH 2 ] 16 0H), a source of tere- phthaloyl units (e.g., dimethyl terephthalate); a source of poly(oxyethylene)oxy units (e.g., polyethylene glycol 1500); a source of oxyiso-propyleneoxy units (e.g., 1,2-propylene glycol); and a source of oxyethyleneoxy units (e.g., ethylene glycol) especially wherein the mole ratio of oxyethyleneoxy unitsoxyiso- propyleneoxy units is at least about 0.5:1.
- Such nonionic soil release agents are of the general formula
- R 1 is lower (e.g., C ⁇ -C 4 ) alkyl, especially methyl; x and y are each integers from about 6 to about 100; m is an integer of from about 0.75 to about 30; n is an integer from about 0.25 to about 20; and R 2 is a mixture of both H and CH 3 to provide a mole ratio of oxyethyleneoxy:oxyisopropyleneoxy of at least about 0.5:1.
- soil release agent useful herein is of the general anionic type described in U.S. Patent 4,877,896, but with the condition that such agents be substantially free of monomers of the HOROH type wherein R is propylene or higher alkyl.
- the soil release agents of U.S. Patent 4,877,896 can comprise, for example, the reaction product of dimethyl terephthalate, ethylene glycol, 1,2-propylene glycol and 3-sodiosulfobenzoic acid
- these additional soil release agents can comprise, for example, the reaction product of dimethyl terephthalate, ethylene glycol, 5-sodiosulfoisophthalate and 3-sodiosulfobenzoic acid.
- Such agents are preferred for use in granular laundry detergents.
- the formulator may also determine that it is advantageous to include a non-perborate bleach, especially in heavy-duty granular laundry detergents.
- a non-perborate bleach especially in heavy-duty granular laundry detergents.
- peroxygen bleaches are avail ⁇ able, commercially, and can be used herein, but, of these, percar ⁇ bonate is convenient and economical.
- the compositions herein can contain a solid percarbonate bleach, normally in the form of the sodium salt, incorporated at a level of from 3% to 20% by weight, more preferably from 5% to 18% by weight and most preferably from 8% to 15% by weight of the composition.
- Sodium percarbonate is an addition compound having a formula corresponding to 2Na 2 C0 3 . 3H 2 0 2 , and is available commercially as a crystalline solid.
- Most commercially available material includes a low level of a heavy metal sequestrant such as EDTA, 1-hydroxyethylidene 1,1-diphosphonic acid (HEDP) or an amino- phosphonate, that is incorporated during the manufacturing process.
- a heavy metal sequestrant such as EDTA, 1-hydroxyethylidene 1,1-diphosphonic acid (HEDP) or an amino- phosphonate
- the percarbonate can be incorporated into detergent compositions without additional protection, but preferred embodiments of the invention utilize a stable form of the material (FMC).
- FMC stable form of the material
- a variety of coatings can be used, the most economical is sodium silicate of Si0 2 :Na 2 0 ratio from 1.6:1 to 2.8:1, preferably 2.0:1, applied as an aqueous solution and dried to give a level of from 2% to 10% (normally from 3% to 5%), of silicate solids by weight of the percarbonate.
- Magnesium silicate can also be used and
- the particle size range of the crystalline percarbonate is from 350 micrometers to 450 micrometers with a mean of approxi ⁇ mately 400 micrometers. When coated, the crystals have a size in the range from 400 to 600 micrometers. While heavy metals present in the sodium carbonate used to manufacture the percarbonate can be controlled by the inclusion of sequestrants in the reaction mixture, the percarbonate still requires protection from heavy metals present as impurities in other ingredients of the product. It has been found that the total level of iron, copper and manganese ions in the product should not exceed 25 ppm and preferably should be less than 20 ppm in order to avoid an unacceptably adverse effect on percarbonate stability.
- EXAMPLE XIV The following illustrates a perborate bleach-plus-bleach activator detergent composition of the present invention which is prepared by admixing the listed ingredients in a mixing drum.
- Zeolite A refers to hydrated crystalline Zeolite A containing about 20% water and having an average particle size of 1 to 10, preferably 2 to 5, microns; LAS refers to sodium C 12 .
- AS refers to sodium C 1 -C 15 alkyl sulfate
- nonionic refers to coconut alcohol con ⁇ densed with about 6.5 moles of ethylene oxide per mole of alcohol and stripped of unethoxylated and monoethoxylated alcohol, also abbreviated as CnAE6.5T.
- DTPA refers to sodium diethylenetri- amine pentaacetate.
- NAPAA wet cake which typically consists of about 60% water, about 2% peroxyacid available oxygen
- This wet cake is the crude reaction product of NAAA (monononyl amide of a.dipic acid), sulfuric acid, and hydrogen peroxide which is subsequently quenched by addition to water followed by filtration, washing with distilled water, phosphate buffer washing and final suction filtration to recover the wet cake.
- a portion of the wet cake is air-dried at room temperature to obtain a dry sample which typically consists of about 5% AvO (corresponding to about 90% NAPAA) and about 10% unreacted starting material. When dry, the sample pH is about 4.5.
- NAPAA granules are prepared by mixing about 51.7 parts of the dried NAPAA wet cake (containing about 10% unreacted), about 11.1 parts of sodium C 12 . 3 linear alkyl benzene sulfonate (LAS) paste (45% active), about 43.3 parts of sodium sulfate, and about 30 parts of water in a CUISINART mixer. After drying, the granules (which contain about 47% NAPAA) are sized by passing through a No. 14 Tyler mesh sieve and retaining all particles not passing through a No. 65 Tyler mesh. The average amide peroxyacid particle (agglomerate) size is about 5-40 microns and the median particle size is about 10-20 microns, as determined by Malvern particle size analysis. 3 The NOBS (nonanoyloxybenzene sulfonate) granules are prepared according to U.S. Patent 4,997,596, Bowling et al , issued March 5, 1991, incorporated herein by reference.
- Zeolite granules having the following composition are made by mixing Zeolite A with PEG 8000 and CnAE6.5T in an Eirich R08 energy intensive mixer.
- Zeolite A (includes bound water) 70.00 76.99 PEG 8000 10.80 12.49
- the PEG 8000 is in an aqueous form containing 50% water and is at a temperature of approximately 55'F (12.8'C).
- the CnAE6.5T is in a liquid state and is held at approximately 90'F (32.2'C).
- the two liquids are combined by pumping through a 12 element static mixer.
- the resulting binder material has an outlet temperature of approximately 75'F (23.9'C) and a viscosity of approximately 5000 cps.
- the ratio of PEG 8000 and CnAE6.5T through the static mixer is 72:28 respectively.
- the Eirich R08 energy intensive mixer is operated in a batch type mode. First, 34.1 kg of powdered Zeolite A is weighed into the pan of the mixer. The mixer is started by first rotating the pan in a counterclockwise direction at approximately 75 rotations per minute (rpm), and then rotating the rotor blade in a clockwise direction at 1800 rpm. The binder material is then pumped from the static mixer directly into the Eirich R08 energy intensive mixer which contains Zeolite A. The feed rate of the binder material is about 2 minutes. The mixer continues to mix for an additional 1 minute for a total batch time of approximately 3 minutes. The batch is then discharged and collected in a fiber drum.
- the batch step is repeated until approximately 225 kg of wet product has been collected. This discharged product is then dried in a fluid bed at 240-270'F (116-132'C). The drying step removes most of the free water and changes the composition as described above.
- the total energy input by the mixer to the product in a batch mode is approximately 1.31X10 12 erg/kg. at a rate of approximately 2.18X10 9 erg/kg-s.
- the resulting free flowing agglomerates have a mean particle size of about 450-500 microns.
- a liquid laundry detergent composition suitable for use at the relatively high concentrations common to front-loading automatic washing machines, especially in Europe, and over a wide range of temperatures is as follows. Ingredient Wt. %
- Amylase from NOVO; percentage at 300 KNU/g. 4 Lipase, from NOVO; percentage at 100 KLU/g. -•Cellulase from NOVO; percentage at 5000 CEVU/1.
- EXAMPLE XVI A granular laundry detergent composition suitable for use at the relatively high concentrations common to front-loading automatic washing machines, especially in Europe, and over a wide range of temperatures is as follows.
- -•SOKALAN sodium poly-acrylate/maleate available from Hoechst.
- X2-3419 is a silicone suds suppressor available from Dow Corning.
- the procedure for preparing the granules comprises various tower-drying, agglomerating, dry-additions, etc., as follows. The percentages are based on the finished composition.
- a surfactant mixture of 20% DOBANOL C 12 . 15 E0(3) and 80% C i6 -C 18 N-methyl glucose amide is obtained and coagglomerated with 10% sodium carbonate.
- the above particle is then coagglomerated with a high active paste (70%) of a sodium salt of C 14 -C 15 alkyl sulfate and
- This particle evidences a good dispersibility in cold water of the C 16 -C 18 N-methyl glucose amide.
- the overall formulation of this particle (contribution to the detergent formulation after the drying of the agglomerate) is: C 16 -C ⁇ 8 N-methyl glucose amide 4.1%
- the silicone suds suppressor X2-3419 (95-97% high molecular weight linear silicone; 3%-5% hydrophobic silica) ex Dow Corning is coagglomerated with Zeolite A (2-5 ⁇ size), starch and stearyl alcohol binder. This particle has the following formulation: Zeolite A 0.22%
- the detergent preparation exhibits excellent solubility, superior performance and excellent suds control when used in a European washing machine, e.g., using 85 g detergent in a AEG- brand washing machine in 30'C, 40'C, 60'C and 90'C cycles.
- the fatty acid glucamide surfactant can be replaced by an equivalent amount of the malt ⁇ amide surfactant, or mixtures of glucamide/maltamide surfactants derived from plant sugar sources.
- the use of ethanolamides appears to help cold temperature stability of the finished formulations.
- the use of sulfobetaine and/or amine oxide surfactants provides superior sudsing.
- compositions where high sudsing is desired it is pre ⁇ ferred that less than about 5%, preferably less than about 2%, most preferably substantially no C 14 or higher fatty acids be present, since these can suppress sudsing. Accordingly, the formulator of high sudsing compositions will desirably avoid the introduction of suds-suppressing amounts of such fatty acids into high sudsing compositions with the polyhydroxy fatty acid amide and/or avoid the formation of C 14 and higher fatty acids on storage of the finished compositions.
- One simple means is to use C 12 ester reactants to prepare the polyhydroxy fatty acid amides herein. Fortunately, the use of amine oxide or sulfobetaine surfactants can overcome some of the negative sudsing effects caused by the fatty acids.
- anionic optical brighteners to liquid detergents containing relatively high concentrations (e.g., 10% and greater) of anionic or polyanionic substituents such as the polycarboxylate builders may find it useful to pre-mix the brightener with water and the polyhydroxy fatty acid amide, and then to add the pre-mix to the final composition.
- Polyglutamic acid or polyaspartic acid dispersants can be usefully employed with zeolite-built detergents.
- AE fluid or flake and DC-544 are other examples of useful suds control agents herein.
