Description

CLEANING COMPOSITIONS CONTAINING DISPERSANTS OF SOAP DEPOSITS AND METHOD FOR PREPARATION BACKGROUND This invention relates to a process for formulating liquid detergent compositions, which have improved dispersancy of lime soap deposits, and liquid cleaning compositions thus formed. In particular, the present invention relates to liquid cleaning compositions having an improved dispersancy of lime soap deposits, containing copolymers formed of maleic acid, maleic anhydride, or its salts, and to a copolymerizable hydrophobic monomer, oligomer or polymer. , which contains 4 to 20 carbon atoms. The use of soap as a cleaning agent is well known. Among the deficiencies, it is known that soap forms insoluble salts in water, in the presence of calcium and magnesium ions (hard water). In hard water, the insoluble salts flocculate to form deposits of a "layer of lime impurities" or "lime soap deposits", which are transferred to clothing or fabrics ("grayish" color, which have been washed or on the surfaces of the container ("ring of the bath tub") in which the washing or rinsing of clothes or fabrics is carried out.
It is convenient to prevent the deposit of lime soap and this has been achieved by the addition of detergents or synthetic surfactants, as dispersants of these deposits of lime soap, to clean the formulations to prevent or minimize the flocculation of insoluble particles from the deposit of lime soap; This dispersed lime soap deposit remains in a finely divided state, so that it does not adhere to surfaces and can be washed and separated during rinsing. However, large quantities of detergents or synthetic surfactants are required to supply the effective dispersion of the lime soap deposit and are added to the cost of the cleaning formulations. It has also been recognized that the use of sequestering agents, for example, citrates, phosphates or polyphosphates, to form metal complexes with calcium or magnesium, can prevent the formation of lime soap particles. The convenience of avoiding phosphates in detergents is well recognized; The compounds, based on phosphorus, when present in lakes, rivers and bays, serve as nutrients for the growth of algae, resulting in the deterioration of water quality. Therefore, it is convenient to minimize the formation or deposit on the washed fabrics or surfaces, without significantly adding the cost of the cleaning formulations, without contributing to environmental contamination and without destabilizing or affecting other properties of the cleaning formulations. Among the approaches used to solve the problem of lime soap deposition in cleaning compositions are the following: U.S. Patent No. 4,797,223, which discloses the use of acrylic acid polymers, partially esterified with polyoxyalkylene ethoxylates, as dispersants of the lime soap deposit, in liquid laundry and dishwashing compositions, for heavy work. Patent EP 147745A discloses the use of acrylic acid polymers, esterified with the polyalkylene glycol and the corresponding copolymers of acrylamidoalkanesulfonic acid, as dispersants of the lime soap deposit in the cleaning compositions. These materials cover a range of efficiency as dispersants of the lime soap deposit and have different levels of compatibility with certain ingredients of cleaning formulations. The following references disclose the use of maleic acid / olefin copolymers in various cleaning compositions. US Pat. No. 5,126,068 discloses the use of polyoxyalkylene block surfactants, in combination with certain polycarboxylate copolymers (including maleic acid / olefin copolymers) in hard surface cleaning compositions., which contain solvents. U.A. Patent No. 5,232,622 discloses the use of maleic acid / olefin copolymers as dispersants in compositions, free of chlorine, for washing dishes in machine. EP 630965A discloses the use of maleic acid / olefin copolymers as crystallization inhibitors in cleaning compositions, liquid and concentrated, for hard surfaces. The problem to which the present invention is directed is to overcome the deficiencies of the above dispersants of lime soap deposits and to provide a method for the formulation of liquid cleaning compositions having increased properties of the lime soap deposit dispersancy, both maintain good physical storage stability.

Bleaching agents useful in liquid cleaning compositions include, for example, chlorine generating substances, such as sodium hypochlorite and chloroisocyanurates. The LSD polymer can be used in cleaning formulations of soaps or detergents and serve different purposes each. Cleaning formulations containing soap depend on the LSD polymer to prevent the accumulation of lime soap deposits in the tubs and containers, in the presence of hard water. Detergent cleaning formulations (which contain one or more anionic and nonionic surfactants, but little or no soap) are dependent on LSD to dislodge and suspend lime soap deposits that are not easily removed from soiled materials by others. components of detergent formulations, thus increasing the "whiteness" of the washing process. The "dispersion potency of the lime soap tank" or LSDP measures the ability of a material to disperse lime soap deposits, using calcium oleate as a model lime soap reservoir. The LSDP is expressed as a percentage and refers to the minimum amount of a material required to disperse a given amount of the lime soap deposit, under standard conditions (see the description of Examples 1-8). A material with a low LSDP value is LSD more effective than a material with a higher LSDP. The LSDP values for the LSD polymers of the present invention are typically less than 30, preferably less than 20, and more preferably less than 15. Low LSDP values mean that relatively small amounts of an LSD polymer need be added to a cleaning formulation to meet the general cleaning requirements and there is a greater likelihood that the resulting composition will be stable, i.e., there is a lower likelihood that the components of the cleaning composition are incompatible. The method of the present invention provides for the preparation of stable liquid cleaning compositions, that is, they remain physically stable in storage and do not settle or precipitate in different phases. The components of the liquid cleaning compositions and their relative proportions are selected so that they are compatible with each other, resulting in stable liquid formulations. In general, satisfactory compatibility of the LSD polymer with a liquid cleaning formulation is indicated if it is greater than 1%, preferably greater than 2% and more preferably greater than 3% by weight of the LSD polymer that can be added to the formulation liquid cleaning while maintaining stability. The liquid cleaning compositions of the present invention are typically prepared by adding the LSD polymer to a mixture of the components of the cleaning composition. The LSD polymer and the components of the cleaning composition do not combine in any particular order; however, it is preferable to dissolve any solid component first in the water, adjust the pH, combine with the liquid components and finally adjust to the desired pH, if necessary. Aqueous solutions of the cleaning compositions of the present invention typically have a pH ranging from 5 to 11.5, preferably from 7 to 10 and more preferably from 7.5 to 9. The polymers of LSD used in the method of the present invention for the Preparation of liquid cleaning compositions can also be used in formulations of solid cleaning compositions. Physical forms of solid cleaning compositions include, for example, powders, granules, flakes, tablets and bars; when the cleaning compositions are in solid form, they must be substantially soluble in the aqueous media used to wash or clean the soiled materials. The amount of the LSD polymer used in the preparation of solid cleaning compositions will generally be from 0.05 to 10% and preferably from 0.25 to 4% by weight of the solid cleaning compositions. Unless indicated otherwise, solid cleaning compositions include, for example, powder laundry, bar soap laundry, personal care bar soap, and dish washing powder compositions. in machine. The amount of soap used in preparing the solid cleaning compositions will generally be from 0.5 to 30% and preferably from 8 to 20% by weight of the powder and laundry compositions of bar soap; from 0 to 50% and preferably from 10 to 30% by weight of the bar soap compositions for personal care; and from 0.5 to 5%, preferably from 0.5 to 3% by weight of the powder compositions for washing dishes in machine. The solid cleaning compositions of the present invention will also contain auxiliary additives. These auxiliary additives are selected from one or more neutral salts, formers, and water-soluble, anionic and non-ionic surfactants, and they vary in their amounts, depending on the physical form and intended use of the solid cleaning composition; the amount of auxiliary additives used will generally be from 20 to 80%, and preferably from 30 to 60% by weight of the solid cleaning composition. The neutral salts (described above) are used as inert diluents in solid cleaning compositions. Examples of these diluents include, for example, sodium or potassium chloride, sodium or potassium sulfate and sodium or potassium nitrite; calcium carbonate can be used as an inert filler in laundry compositions of bar soaps. The amount of neutral salts used is typically 0 to 60% and preferably 0 to 30%, based on the weight of the solid cleaning compositions.
The amount of the former (described above) used in the solid cleaning compositions will generally be from 0 to 80% and preferably from 0 to 40% by weight of the laundry powder compositions, for example, the zeolite (such as the aluminosilicate sodium) can be added in amounts of 0 to 50% and preferably 20 to 40% by weight; from 10 to 40% by weight of the bar soap laundry compositions; from 0 to 10% by weight of the bar soap compositions for personal care and from 0 to 60%, preferably from 0 to 40% by weight of the powder compositions for machine dishwashing. The combined amount of the nonionic and anionic surfactant (described above) used in the solid cleaning compositions will depend on the surfactant selected and will generally be 10 to 50% and preferably 10 to 30% by weight of the laundry compositions in powder, laundry bar soap and bar soap for personal care; and from 0.1 to 10%, preferably from 0.2 to 5% by weight of the powder compositions for washing dishes in the machine. The combined amount of the nonionic and anhydride surfactants in the liquid cleaning compositions can be all of one type, ie all surfactants are nonionic or anionic.
The solid cleaning compositions of the present invention may also contain water in the form of absorbed or entrained moisture, the amount of water will typically be from 0 to 10% and preferably from 0 to 5% by weight of the solid cleaning composition. Optional modifying additives may also be used in conjunction with the LSD polymers, soaps and auxiliary additives in the solid cleaning compositions of the present invention. These optional modifying additives include, for example, corrosion inhibitors (in amounts ranging from 0 to 40%, preferably from 0 to 20% by weight in the machine dishwashing powder compositions, and from 0 to 12%, preferably from 0 to 6% by weight in laundry compositions n powder), bleaching agents, such as perborates, percarbonates and calcium hypochlorite (in amounts ranging from 0 to 30%, preferably from 0 to 20% by weight in the laundry powder compositions, and from 0 to 20%, preferably from 0 to 15% by weight of the powder compositions for the washing of dishes in machine), additional surfactants, water soluble, enzymes, stabilizers, agents against redeposition, optical brighteners, dyes, softeners, preservatives, opacity formers, dye transfer inhibitors, regulating agents, perfumes and bactericides. The amount of the optional modifying additives that can be added to the solid compositions will generally be from 0 to 50% and preferably from 0 to 30% by weight of the composition. Only a small amount of cleaning compositions is typically required in aqueous media to achieve satisfactory cleaning of soiled materials. For example, from 0.01 to 0.5%, based on the combined weight of the cleaning composition and the aqueous medium, is sufficient to provide satisfactory cleaning of dirty clothes, fabrics and dishes; For highly soiled materials, 0.5 to 1% of the cleaning composition in the aqueous medium can be used. "Dirty materials" as used herein include, for example, soiled fabrics, dirty clothes, dirty parts of the human body and dirty hard surfaces, such as tableware, floors and walls. The aqueous solutions of the cleaning compositions of the present invention are effective in cleaning soiled materials over a wide range of wash water temperatures, typically from 5 to 952V, preferably from 15 to 80BC and more preferably from 25 to 60ac. Some embodiments of the invention will be described in detail in the following examples. All relationships, parts and percentages (%) are expressed by weight, unless otherwise specified, and all reagents used are of good commercial quality, unless otherwise specified. EXAMPLES 1-9 (Litter Jacket Decanting Test Using a procedure based on a test described by HC Borghetty and CA Bergman in J. Am. Oil Chem. Soc.% J_ pages 88-90 (1950) was measured "potassium dispersancy strength of lime soap" ("LSDP") of the water-soluble polymers of the present invention and compared with those of various polymers of acrylic acid and maleic acid The purpose of the test is to measure visual means the minimum amount of a lime soap deposit dispersant ("LSD"), required to disperse a given quantity of calcium oleate (model lime soap reservoir) in very hard water.The results given in Table 1 indicate that the polymers of the present invention (Examples 4-8) are superior to the comparative polymers, based on the acrylic acid homopolymer (Example 1), the acrylic acid / maleic acid copolymer (Example 2) and the homopolymer of the acid malefic (Example 3) in the dispersancy of the lime soap tank. The potency of the lime soap deposit dispersion (LSDP) is the ratio of the weight percentage of the dispersant of the lime soap deposit to the sodium oleate, required to disperse the lime soap deposits formed by 0.025 g of the oleate of sodium in 30 ml of water containing 333 ppm (parts per million by weight) of calcium carbonate (Ca2 + / Mg2 + = 3/1) hardness equivalents. Five ml of a 0.5% by weight solution of sodium oleate was added to the test tube, followed by several amounts (less than 15 ml) of the lysine detergent dispersant as a 1% by weight solution (pH = 7-10). A solution of hard water (10 ml) containing 750 ppm of Ca2 + and 250 ppm of Mg2 (1000 ppm as CaC03 equivalent) that caused the formation of a deposit of lime soap was then added and the total volume of the solution in the Test tube was brought to 30 ml with deionized water. The test tube was capped, inverted 20 times and then allowed to stand for 30 seconds. The solutions were examined visually to determine if the lime soap deposits were intact or if they were dispersed in the solution. The test procedure was repeated using different amounts of the dispersing solution of lime soap deposits, until a minimum amount of the dispersing solution of the lime soap tank that will disperse the lime soap deposits is obtained. According to the test method described, a material with a lower value of the LSDP is a more effective dispersant of the lime soap deposit than a material with a higher LSDP. When two values for the LSDP are listed in Table I, for example, 10-20, this means that the LSDP is greater than the first number (10) and less than the second number (20). [weight of the dispersant of lime soap] LSDP (%) = x 100 [weight of sodium oleate] The abbreviations used in the Tables are listed below, with the corresponding descriptions: AA - Acrylic acid MAL = Maleic acid STY = Styrene DIB = Diisobutylene LIM = Limonene LIN = Linalool NA = Not analyzed.
TABLE I Example 10 Compatibility with Liquid Detergent Formulations The polymers of the present invention were added to a commercial liquid detergent formulation, initially at a level of 0.5% (0.5 in Table I) by weight in the commercial formulation and increased to levels older when compatibility is found. Test conditions: "X" grams of aqueous solution of the LSD polymer ("X" based on the polymer solids and the desired test level) were added to "100-X" grams of the heavy duty liquid detergent. For example, to test an LSD polymer, available as a solution at 25% solids in water at a compatibility level of 0.5% in a commercial formulation, one will take 2 grams of the LSD solution [2 x 0.25 = 0.5] and will add them to 98 grams of the commercial formulation. If the same solution of the LSD polymer is to be tested at a compatibility level of 3%, one will take 12 grams of the LSD solution [12 x 0.25 = 3] and add them to 88 grams of the commercial formulation. All compatibility tests were performed in 25 gram portions of the solution. The commercial heavy duty liquid detergent used was Ultra Vizir, available from Proctor and Gamble France and contained "5-15% of a nonionic surfactant, 5-15% jabdn, 15-30% of an anhydrous surfactant, enzymes, optical brightener and less than 5% phosphonate. " The test formulations were observed in stability (compatibility or without phase separation) as a function of time, typically by at least 24-48 hours up to about 2 weeks. Compatibility is defined as the maintenance of a stable solution, that is, there is no sedimentation of the components or phase separation. As shown in Table I (last column), the polymers of the present invention (Examples 4 to 8) were more compatible in the commercial liquid detergent formulation with high surfactant content than the acrylic acid homopolymer (Example 1) ) or the acrylic acid / maleic acid copolymer (Example 2). The compatibility values of 0.5, 2 and 4 in Table I refer to 0.5%, 2% and 4% by weight, respectively, of the LSD polymer added to the commercial formulation. A second heavy-duty commercial liquid detergent was also used to evaluate the compatibility of a polymer of the present invention. In this case, Example 4B had a compatibility > 4, when the commercial liquid heavy duty detergent used was the Le Chat Compact liquid detergent (available from Henkel France, which contains "5-15% of the anhydrous surfactant, 5-15% jabdn, 15-30% of the surfactant. non-ionic, enzymes and perfume "). Example 11 (Cleaning of Dirty Materials An important feature of the cleaning process is the performance against the redeposition of the cleaning composition.The anti-redeposition properties of a commercial formulation of heavy-duty liquid detergent together with various polymers of LSD are presented in Table II In addition to dispersing the lime soap deposits present in the dirty materials to be cleaned, a satisfactory cleaning formulation must also prevent the "dirt" from being dispersed or removed from being re-deposited onto clothes, fabrics or clean surfaces A measure of property against redeploy is the whiteness index of clean fabrics, the higher the value, the better the property against redeposition of the formulation As shown in Table II, a polymer of the present invention was at least equal to or better than the acrylic acid / maleic acid copolymer or the homopolymer of conventional maleic acid in the property against the redepdsite and does not reduce the cleaning efficiency of the commercial detergent formulation. The cleaning test was carried out as follows: Kenwood commercial washing machines, Mini-E were filled with 6 liters of running water; Calcium chloride and magnesium chloride were added to the water to give a hardness of 300 ppm, calculated as calcium carbonate (Ca2 + / Mg2 + = 3/1). The washing machines were loaded with approximately 500 grams of fabrics (all cotton sponge fabrics, cotton fabrics and cotton / polyester blends). Then, 7.2 grams of dirt (4.0 grams of used motor oil and 3.2 grams of canned dirt) were added to the washing machine, followed by the addition of cleaning compositions to be tested. The fillers of the dirty fabrics were treated by 5 complete wash cycles (30 minutes each) with hot conditions (402C), with the addition of dirt and cleaning composition before each cycle. The tested cleaning compositions were composed as follows: commercial detergent: Ultra Vizir liquid detergent (described above, Example 10) added in each charge to 6 grams / liter of water; LSD polymer added in each charge to 2% by weight of polymer solids, based on the weight of the Ultra Vizir liquid detergent used. The data in Table II are the values of the Whiteness index, obtained from the washed fabrics. This Whiteness Index was calculated as follows: Whiteness Index ("Wl") = 3.387 [Z] - 3 [Y] where Y and Z are the reflectance values, measured using a Pacific Scientific Colorimeter (Colorgard System 1000).
TABLE II Example 12 Cleaning of Dirty Materials A second evaluation of the cleaning was conducted similarly to that described in Example 11, except that the commercial liquid detergent used was the Le Chat Compact (described above, Example 10) instead of the Ultra Vizir liquid detergent. As shown in Table III, the polymer of the present invention was at least equal to or better than the control (Le Chat Compact detergent alone) or a conventional acrylic acid / maleic acid copolymer in performance against redeposition in sponge fabrics or of cotton, and significantly better than the control of conventional acrylic acid / maleic acid copolymer in polyester / cotton fabrics. The cleaning test was carried out as follows: Kenwood Mini E washing machines were filled with 6 liters of running water; Calcium chloride and magnesium chloride were added to the water to provide a hardness of 300 ppm, calculated as calcium carbonate (Ca2 + / Mg2 + - 3/1). The washing machines were loaded with approximately 500 grams of fabrics (all cotton sponge cloth, cotton cloth and cotton / polyester blends). Next, 7.2 grams of dirt (4.0 grams of used motor oil and 3.2 grams of canned dirt) were added to the washing machine, followed by the addition of the cleaning compositions to be tested. The loads of the dirty fabrics were treated during 10 complete wash cycles (30 minutes each) under hot conditions (40QC), with the addition of the dirt and the cleaning composition before each cycle. The tested cleaning compositions were composed as follows: commercial detergent: Le Chat Compact liquid detergent (described above, Example 10) added to each charge at 6 grams / liter of water; LSD polymer added to each charge at 0.5% by weight of polymer solids, based on the weight of the liquid detergent Le Chat COmpact used. The data in Table III are the values of the Whiteness indices obtained from the washed fabrics. TABLE III
