Other silicates may also be useful, such as, for example, magnesium silicate, which may serve as a tightening agent in granular formulations, as a stabilizing agent for oxygen bleaches, and as a component of foam control systems. Examples of carbonate builders are alkali metal carbonates and bicarbonates. The preferred one is sodium carbonate. The aluminosilicate builders are useful in the subject compositions. Aluminum aluminosilicate builders are of great importance in many granular detergent compositions currently sold. The aluminiosilicate builders include those that have the empirical formula Mz (2Al? 2) and. vH? Or where z and y are integers of at least 6, the molar relation of z to y is on the scale from 1.0 to 0.5, and v is an integer from 15 to 264.
Useful aluminosilicate ion exchange materials are commercially available. These alumiposilicates can be crystalline or amorphous in structure and can be aluminosilicates that occur naturally or synthetically derived. A method for producing aluminosilicate ion exchange materials is described in U.S. Patent 3,985,669, Krummel et al., October 12, 1976. The preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A. Zeolite P (B), Zeolite MAP and Zeoite X. In an especially preferred embodiment, the crystalline aluminosilicate ion exchange material has the formula Nai2 ((AI02) i2 (S02) 12) -vH20 where v is from 20 to 30, especially 27 This material is known as Zeolite A. Dehydrated zeolites (v = 0-10) can also be used. Preferably, the aluminosilicate has a particle size of 0.1-10 microns in diameter. Organic builders suitable for the subject compositions include, but are not restricted to, a wide variety of polycarboxylate compounds. As used herein, "polycarboxylate" refers to compounds having a plurality of carboxylate groups, preferably at least three carboxylates. Preferred polycarboxylate builders include citrates, succinates and oxydisuccinate. The polycarboxylate builders can generally be added to the compositions in acid form, but can also be added in the form of neutralized salts, such as sodium.

Such a chelating agent may be selected from the group consisting of aminocarboxylates, amiphosphonates, polyfunctionally substituted aromatic chelating agents and mixtures thereof. Without attempting to be attached to the theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from the wash solutions by the formation of soluble chelators. This agent is also useful in bleaching stabilizing components of the present compositions.

Those skilled in the art of alkoxylation of poiyalkyleneamines recognize that the "degree of ethoxylation" is defined as the average number of alkoxylations by nitrogen atom substitution sites and can be expressed as a fractional number.A polyalkyleneamine can have an equal degree of ethoxylation at 1 or greater and still have less than 100% of the substituted nitrogen-substituted polyalkyleneamine base structure sites The relative proportion of primary, secondary, and tertiary amine units in the polyalkyleneamine base structure will vary, depending on the mode PREPARATION OF THE BASE STRUCTURE Preferred "polyalkyleneamine base structures" herein include both polyalkyleneamine (PAA) and polyalkyleneimine (PAI); The preferred base structures are polyethylepamine (PEA) and polyethyleneimines (PEI). is obtained by a reaction involving ammonia and ethylene dichloride, followed by distillation n fractionated. The common PEAs include triethylenetetramine (TETA), tetraethylenepentamine (TEPA), and tetrabutilenpentamina. Above pentamine, ie hexamine, heptamine, octamine and possibly nonamine, the congenically derived mixture is not easily separated by distillation and may include other materials such as cyclic amines and piperazines. Cyclic amines may also be present with side chains in which nitrogen atoms appear. See U.S. Patent 2,792,372, Dickinson, issued May 14, 1957, incorporated herein by reference, which describes the preparation of PEA. The PEI includes the preferred polyalkyleneamine base structures, useful herein. The PEI can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfate, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc. The specific methods for preparing PEIs are described in U.S. Patent 2,182,306, Ulrich et al., Issued on 5 December 1939; U.S. Patent 3,033,746, Mayle et al., May 8, 1962; U.S. Patent 2,208,095, Esselmapn et al., July 16, 1940; U.S. Patent 2,806,839, Crowther, September 17, 1957; and U.S. Patent 2,553,696, Wilson, May 21, 1951 (all incorporated herein by reference). In addition to the linear and branched compounds of PEIs, compounds useful herein also include cyclic amines that are typically labeled as synthetic artifacts. The presence of these materials can be increased or decreased depending on the conditions chosen by the formulator. The following is a non-limiting example of the synthesis of a preferred soil dispersion agent. Preparation of PEÍ 1800 E7: The "PEÍ 1800 E7" has a base structure of polyethyleneimine having an average molecular weight of approximately 1800, a ratio of q: r of about 1: 2, and an average degree of ethoxylation of about 7. The ethoxylation is carried out in a stirred stainless steel autoclave of 7.56 liters equipped for temperature measurement and control, pressure measurement, purging of vacuum and inert gas, sampling, and introduction of ethylene oxide as a liquid. A cylinder of -9.08 kg. Net weight of ethylene oxide is prepared to supply the ethylene oxide as a liquid by pumping the autoclave with the cylinder placed on a scale, so that the weight change of the cylinder can be monitored. A 750 g portion of PEI (Nippon Shokubai, EPOMIN SP-018® having an average molecular weight listed of 1800 and a q: r ratio of approximately 1: 2), equaling approximately 0.417 moles of the polymer and 17.4 moles of sites of nitrogen substitution, is added to the autoclave. The autoclave is then sealed and purged of air (by applying the vacuum to minus 12.702 kg of Hg, followed by pressurization with nitrogen at 17.575 kg / cm2, then ventilating it at atmospheric pressure). The contents of the autoclave are heated to 130 ° C while applying vacuum. After about one hour, the autoclave is charged with nitrogen at about 17.575 kg / cm2, while cooling in the autoclave at about 105 ° C. The ethylene oxide is then added to the autoclave incrementally over time while closely monitoring the pressure, temperature and flow rate of ethylene oxide in the autoclave. The ethylene oxide pump is turned off and applied e! cooling to limit any temperature increase that results from any exothermic reaction. The temperature is maintained between 100 and 110 ° C while the total pressure can be gradually increased during the course of the reaction to a maximum of about 24605 kg / cm2. After a total of 750 grams of ethylene oxide has been charged to the autoclave (barely equivalent to an ethylene oxide mold per PEI nitrogen substitution site), the temperature is increased to 110 ° C and the autoclave can be stirred for an additional hour. At this point, the vacuum is applied to remove any ethylene oxide without residual reaction. (If a degree of ethoxylation of 1 is desired, the procedure will proceed directly to the next deodorization step). The vacuum is then continuously applied while the autoclave is cooled to approximately 50 ° C while introducing 376 g of 25% sodium methoxide in a metapol solution (1.74 moles) to achieve 10% catalyst loading based on the nitrogen substitution sites PEÍ). The methoxide solution is sucked into the vacuum autoclave and then the temperature control point of the autoclave is increased to 130 ° C. A device is used to monitor the energy consumed by the agitator. The energy of the agitator is monitored together with the temperature and pressure. The energy and temperature values of the agitator increase gradually as the methane is removed from the autoclave and the viscosity of the mixture increases and stabilizes at approximately 1 hour, indicating that most of the methanol has been removed. The mixture is heated and further stirred under vacuum for an additional 30 minutes. The vacuum is removed and the autoclave is cooled to 105 ° C while it is charged with nitrogen at 17,575 kg / cm2 and then it is ventilated at atmospheric pressure. The autoclave is charged at 14.06 kg / cm2 with nitrogen. The ethylene oxide is added back to the autoclave in an increased manner as above while closely monitoring the pressure, temperature and flow velocity of the ethylene oxide in the autoclave while maintaining the temperature between 100 and 110 ° C and is limited any increase in temperature due to the exothermic reaction. After the addition of 4500 g of ethylene oxide (resulting in a total of 7 moles of ethylene oxide per mole of the PEI nitrogen substitution site) it is achieved in several hours, the temperature is increased to 110 ° C and the mixture is stirred for an additional hour. The reaction mixture is then collected in purged nitrogen containers and then transferred into a 22-L 3-neck round-bottomed flask equipped with heating and stirring. The strong alkaline catalyst is neutralized by adding 167 g of methanesulfonic acid (1.74 moles). The reaction mixture is then deodorized by spraying with inert gas (argon or nitrogen) by gas dispersion fritting and by the reaction mixture for about 1 V4 while stirring and heating the mixture to about 100-130 ° C.
Enzymes Enzymes can be included in the subject compositions for a wide variety of purposes for fabric laundry, including the removal of protein-based, carbohydrate-based or triglyceride-based stains, for example, and for the prevention of the transfer of shelter dye and for the restoration of the fabric. Enzymes that can be incorporated include proteases, amylases, lipases, cellulases, and peroxidases, as well as mixtures of two or more thereof. Other types of enzymes can also be included. Said enzymes may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. However, their selection is governed by several factors such as the activity of pH and / or optimum stability, thermostability, stability in the presence of active detergents, detergency builders and the like. In this regard, bacterial or fungal enzymes, such as bacterial amylases and proteases, and fungal cellulases are preferred. The subject compositions typically comprise from 0% to about 5%, preferably from about 0.1% to about 2%, most preferably from about 0.5% to about 1.5% of commercial enzyme preparations. Suitable examples of proteases are the subtilisins that are obtained from the particular strains of B. subtills and B. licheniforms. Another suitable protease is obtained from a Bacillus strain, having a maximum activity on the pH scale of 8-12, developed and sold by Novo Industries A / S under the registered trade name ESPERASE®. The preparation of said enzyme and analogous enzymes is described in British patent specification no. 1, 243,784 from Novo. Suitable proteolytic enzymes for removing protein-based stains that are commercially available include those sold under the trade names ALCALASE® and SAVINASE® by Novo Industries A / S (Denmark) and MAXATASE® by International Bio-Synthetics, Inc. (Netherlands). The protease enzymes are included in the commercial preparations in the subject compositions at levels sufficient to provide from about 0.004 to about 2 Anson units (AU) of activity per gram of the compositions, preferably from about 0.006 to about 0.1 AU, also from about 0.005 to approximately 0.02 AU. Amylases include, for example, α-amylases described in British patent specification no. 1, 296,839 (Novo), RAPIDASE®, International Bio-Synthetics, Inc. and TERMAMYL®, Novo Industries. The amylase is preferably included in the subject compositions so that the activity of the amylase is from about 0.02 KNU to about 5 KNU per gram of the composition, most preferably from about 0.1 KNU to about 2 KNU, most preferably still from about 0.3. KNU to approximately 1 KNU (KNU is a unit of activity used commercially by Novo Ind.). Useful cellulases in the subject compositions include bacterial and fungal cellulases. Preferably, they will have an optimum pH between 5 and 9.5. The cellulases described in the PCT patent application No. WO 91/17243, such as CAREZYME® (Novo), are especially useful cellulases. The cellulase is preferably included in the subject compositions, so that the activity of the cellulase is approximately 0.1.
CEVU at about 20 CEVU per gram of the composition, most preferably from about 1 CEVU to about 10 CEVU, most preferably from about 2 CEVU to about 5 CEVU. (The activity of a cellulase material (CEVU) is determined from the reduced viscosity of a standard CMC solution of the following way. A substrate solution containing 35 g / l of CMC (Hercules 7 LFD) is prepared in a tris pH regulator of 0.1 M at a pH equal to 9.0. The cellulase sample to be analyzed is dissolved in the same pH regulator. 10 ml of substrate solution and 0.5 ml of enzyme solution are mixed and transferred to a viscometer (ie, Haake VT 181, NV sensor, 181 fm), thermofixed at 40 ° C. Viscosity readings are taken as soon as possible after mixing and again 30 minutes later. The activity of a ceiulase solution that reduces the viscosity of the substrate solution by half under these conditions is defined as 1 CEVU / liter).
Lipase enzymes suitable for detergent use include those produced by microorganisms of the pseudomonas group, such as a Pseudomonas stutzeri ATCC 19,154, as described in British Patent 1, 372,034. The LIPOLASE® enzyme derived from Humicola lanuginosa and commercially available from Novo (see also EP 341 947) is a preferred lipase. The lipase is preferably included in the subject compositions, so that the activity of the lipase is from about 0.001 KLU to about 1 KLU per one gram of the composition, most preferably from about 0.01 KLU to about 0.5 KLU, most preferably still from approximately 0.02 KLU to approximately 0.1 KLU. (KLU is a unit of activity used commercially by Novo Ipd.). Peroxidase enzymes are used in combination with oxygen sources, ie, percarbonate, perborate, persuiphate, hydrogen peroxide, etc. These are used for "solution bleaching", that is, to prevent the transfer of dyes or pigments removed from the substrates during washing operations to other substrates in the wash solution. A large scale of enzyme materials and means for their incubation in synthetic detergent compositions are also described in the US patent. 3,553,139, issued on January 5, 1971 to McCarty et al. The enzymes are also described in the patent of E.U.A. 4,101, 457, Place et al., Issued July 18, 1978, and in the patent of E.U.A.4,507,219, Hughes, issued March 28, 1985. Enzymes for use in detergents can be stabilized by various techniques. Enzyme stabilization techniques are described and exemplified in the U.S. patent. 3,600,319, issued August 17, 1971 to Gedge et al., And European patent application no. 199 405, published on October 29, 1986, Venegas. Enzyme stabilization systems are also described, for example, in E.U.A. 3,519,570.
Bleaching compounds-bleaching agents in bleach activators The subject detergent compositions may optionally contain bleaching agents or a bleaching composition containing a bleaching agent and one or more bleach activators. The bleaching agent is typically at a level of from 0% to about 25%, preferably from about 5% to about 20% of the subject compositions. The amount of the bleach activator is typically from 0% to about 10%, preferably from about 0.5% to about 5% of the subject compositions. The bleaching agent can be any of the bleaching agents useful for detergent compositions in textile cleaning, 4 hard surface cleaning, or other cleaning purposes that are now known or are about to be known. The above include oxygen bleaches as well as other bleaching agents. Perborate bleaches, ie, sodium perborate (ie, mono-tetrahydrate) can be used. A preferred level of perborate bleach in the subject composition is from about 5% to about 20%, most preferably from about 10% to about 16%. Another category of bleaching agent that can be used comprises percarboxylic acid bleaching agents and salts thereof. Suitable examples of such a class of agents include magnesium monoperoxyterephthalate hexahydrate, the magnesium salt of metachloroperbenzoic acid, 4-nonylamino-4-oxoperoxybutyric acid, diperoxidedecanodiolco acid and 6-nonylamino-6-oxoperoxycaproic acid. Other peroxygen bleaching agents can also be used. Suitable peroxygen bleach compounds include sodium carbonate peroxidate and equivalent "percarbonate" bleaches, sodium pyrophosphate peroxydrate, urea peroxydrate, and sodium peroxide. Persulfate bleach (ie, OXONE®, commercially manufactured by DuPont) can also be used. Mixtures of bleaching agents can also be used. The peroxygen bleaching agent (perborate, percarbonate, etc.) is preferably combined with a bleach activator, which it leads to the production in situ in the aqueous solution (ie, during the washing process) of the peroxyacid corresponding to the bleach activator. Several non-limiting examples of activators are described in the U.S. patent. 4,915,854 issued April 10, 1990, to Mao et al., And patent of E.U.A. 4,412,934. The activators of nananoiloxibenzensulfonato (NOBS) and tetracetylethylenediamine (TAED) are typical and mixtures thereof can also be used as well. A preferred level of bleach activator of NOBS or TAED in the subject compositions is from about 0.5% to about 5%, most preferably from about 0.8 to about 3%, most preferably still from about 1.2% to about 2.5%.
Fabric Softening Clay A preferred fabric softening clay is a smectite-like clay. Smectite-type clays can be described as expandable, three-layered clays, ie, aluminosilicates and magnesium silicates, having an ion exchange capacity of at least about 50 meq / 100 g of clay. Preferably the clay particles have a size that can not be perceived tactilely, so that they do not have a gritty feel in the treated fabric of the garments. Fabric softening clay, if desired, may be included in the compositions of the subject invention at levels of approximately 0.1% to approximately %, preferably from about 0.2% to about 15%, most preferably from about 0.3% to about 10%. Although any of the smectite-type clays is useful in the compositions of the subject invention, certain clays are preferred. For example, Gelwhite GP is an extremely white form of smectite-like clay and is therefore preferred to formulate white detergent compositions. Volclay BC, which is a smectite-type clay mineral containing at least 3% iron (expressed as Fe203) in the glass mesh, and which has a very high ion exchange capacity, is one of the more efficient and effective clays to be used in instant compositions from the point of view of product development. On the other hand, certain smectite clays are sufficiently contaminated by other silicate minerals that their ion exchange capacities are within the scale of requirement; said clays are not preferred in the subject compositions.
Clay flocculating agent It has been found that the use of a clay flocculating agent in a softening clay containing composition provides an improved softening clay distribution in the garments, which results in a better fabric softening development, compared to the compositions that they comprise only softening clay. The polymer clay flocculating agent is selected to provide the improved distribution of the clay fabric softener. Typically such materials have a high molecular weight, greater than about 100,000. Examples of such materials may include long-chain polymers and copolymers derived from the monomers such as ethylene oxide, acrylamide, acrylic acid, dimethylaminoethyl methacrylate, vinylalcohol, vinylpyrrolidopa and ethylenimine. Gums, like guar gums, are also suitable. The preferred clay flocculating agent is a poly (ethylene oxide) polymer. The amount of clay flocculating agent included in the subject compositions, if any, is about 0.2% -2%, preferably about 0.5% -1%.
Dye transfer inhibiting ingredient Another optional component in the subject compositions is a dye transfer inhibiting ingredient (DTI) to prevent the decrease in color fidelity and intensity in the fabrics. A preferred polymeric DTI material is capable of binding fugitive dyes to prevent them from depositing on the fabrics. Non-limiting examples of the polymeric DTI materials include polyvinyl pyridine N-oxide, polyvinyl pyrrolidone (PVP), PVP-polyvinylimidazole copolymer, and mixtures thereof. Copolymers of N-vinylpyrrolidone and N-vinyiimidazole polymers (called "PVPI") are also preferred. The amount of DTI included in the subject compositions, if any, is about 0.05% -5%, preferably about 0.2% -2%.
Photoblank A preferred optional component of the composition of the The subject invention is a photobiocidal material, particularly phthalocyanine photobleaching agents which are described in the U.S. patent. 4,033,718, issued July 5, 1977, hereby incorporated by reference.
