Description

DETERGENT COMPOSITIONS COMPRISING ALKALINE POLYGALACTURQNASE TECHNICAL FIELD This invention relates to detergent compositions that include compositions for household cleaning, dishwashing and laundry washing, containing alkaline polygalacturonase enzyme substantially free of other pectic enzymes.
BACKGROUND OF THE INVENTION The overall performance of a detergent product, to be used in a washing or cleaning method, such as a laundry or dishwashing method, is judged by many factors, including the ability to remove dirt, and the ability to avoid the redeposition of the dirt, or the degradation products of the dirt on the articles in the wash. The removal of stains that come from plants, wood, dirt based on clay mud and fruits is one of the most difficult cleaning tasks at present; in particular with tendencies to change at low wash temperatures. These stains typically contain complex mixtures of fibrous material based primarily on carbohydrates and their derivatives: fibers and cell wall components. Soils of vegetable origin are also accompanied by amylose, sugars and their derivatives. Food stains are often difficult to remove effectively from a dirty substrate. Highly stained or "dried" soils derived from fruit and / or vegetable juices are particularly difficult to remove. Specific examples of such dirt would include soils of orange juice, tomato juice, banana, mango or broccoli. The substrates can be fabrics, crockery or hard surfaces. The pectic substances are found, for example, in fruit juices. The pectic substances act to keep dispersed particles in suspension in said fruit juices, which will tend to be viscous and opaque in nature.
Pectic enzymes are commonly used in the fruit / vegetable juice processing industry in the clarification of juices by degradation of pectic substances in them (depectinization). The German patent specification 3,635,427, published on April 23 by Lion Corporation, is directed to phosphate-free detergents for cleaning fabrics containing enzymes with pectinase activity, which are said to include enzymes such as polygalacturonase, pectin lyase and / or pectin esterase. However, in addition to the general teachings in the same related to mixtures of these pectinase enzymes for removal of the inorganic dirt of fabrics, the only specific teaching related to an individual pectinase enzyme is found in example 3, where the enzyme (designated as "Enzyme D") is characterized as an enzyme that contains a large amount of pectin lyase. Table III provides the results of the evaluation of this enzyme D in a detergent formulation, indicating that this mixture of high pectin lyase content has the highest percentage of pectinase activity (10%) and one of the highest detergency values. (83%) in combination with water-soluble high molecular weight compounds compared to compounds with other enzyme compositions reported. The benefits for the specific use of polygalacturonase enzyme which is substantially free of other pectic enzymes in detergent formulations, particularly those designed for use in laundry, dishwashing and household cleaning operations have been recognized in the patent application of E.U.A. Copendent US08 / 529816. It is an object of the present invention to provide laundry detergent, dishwashing or household cleaning compositions that provide improved soil / stain removal benefits when used in washing and cleaning operations. In accordance with the present invention, it has now surprisingly been found that the polygalacturonase enzyme having at least 10%, preferably 25%, most preferably 40% of its optimum activity, at a pH ranging from 7 to 11 and in particular with an optimum activity at a pH ranging from 7 to 11 significantly improves the removal of a wide range of spots based in plants and fruits and increases the actual cleaning profile of the detergent compositions. In fact, the inclusion of the alkaline polygalacturonase enzyme provides in particular improved removal of dirt and stains from dried fruit and vegetable juices. In addition, it has been found that the alkaline polygalacturonase enzyme substantially free of other pectic enzymes exhibits improved compatibility and increased activity in the wash solution thus providing improved removal of soils and body fluid stains, dried fruit and vegetable juices, especially when they come from heavy-duty laundry and ware washing compositions. It has also been found that the alkaline polygalacturonase enzyme substantially free of other pectic enzymes demonstrates better compatibility with detergent matrix, for example, during processing and shelf-life of the product. Furthermore, it has also been surprisingly found that the inclusion of dispersants, particularly organic polymeric dispersants, is of great value in detergent compositions containing alkaline polygalacturonase enzymes.
The dispersants help to the dispersion of the degradation products of the enzymatic degradation of the dirt, thus preventing its redeposition in articles that are in the washing water. The improved cleaning performance has also been observed when the alkaline polygalacturonase enzymes are combined with other detergent enzymes. The bleaching system or conventional activated bleaching system together with alkaline polygalacturonase enzymes provides increased performance benefits over a wide range of blemishes. In addition, polymers that provide inhibition of dye transfer combined with alkaline polygalacturonase enzymes result in improved properties of maintenance of whiteness and / or release of dirt.
BRIEF DESCRIPTION OF THE INVENTION The present invention relates to detergent compositions, including dishwashing compositions, hard surface cleaning and laundry washing containing an alkaline polygalacturonase enzyme substantially free of other pectic enzymes for improved overall cleaning performance and stain removal / dirt removal benefits. increased and in particular improved removal of dirt and stains from fruit and vegetable juices.
DETAILED DESCRIPTION OF THE INVENTION Alkaline polygalacturonase enzyme An essential component of the detergent compositions of the invention is an alkaline polygalacturonase enzyme. The term "alkaline" is intended to cover polygalacturonase enzyme having an enzymatic activity of at least 10%, preferably 25%, most preferably 40% of its optimal activity, at a pH ranging from 7 to 11 and to cover polygalacturonase enzyme having its optimal activity at a pH ranging from 7 to 11. Enzymatic activity can be measured according to "Assay of APGase" described by K. Horikoshi in Agr. Biol. Chem. Vol. 36 (2), 286. As used herein, "substantially free of other pectic enzymes" means compositions containing polygalactinase enzyme containing less than 50% pectic enzymes that are not polygalactanase alkaline enzymes, preferably less about 25%, most preferably less than about 10%, and most preferably still about 5%. Said pectic enzymes include, for example, the pectin methylesterases that hydrolyze the pectin methyl ester bonds, and the pectin transeliminases or lyases that act on the pectic acids to produce non-hydrolytic cleavage of alpha-1-4 glycosidic bonds to form unsaturated derivatives of galacturonic acid. The polygalactinase alkaline enzyme is preferably incorporated in the compositions according to the invention at a level of from 0.0001% to 2%, preferably from 0.0005% to 0.5%, most preferably from 0.001% to 0.1% pure enzyme by weight of the total composition . By alkaline polygalactinase enzyme is meant any enzyme that acts to break down substances by cleaving the bonds between molecules of galacturonic acid. Pectic substances can be found in vegetable teas, and are common constituents of fruit juices such as orange, tomato and grape juices. The pectic substances contain galacturonic acids and / or their derivatives. Pectic substances include pectins and pectic acids. Pectins are, in general, polymers made of chains of galacturonic acids linked by alpha-1,4-glycosidic bonds. Typically, in natural pectins approximately two-thirds of the carboxylic acid groups are esterified with methanol. The partial hydrolysis of these methyl esters gives pectins with low methoxyl content, which tend to form gels with calcium ions. Complete hydrolysis with methyl ester gives pectic acids. The alkaline polygalacturonase enzymes herein include natural alkaline polygalacturonase enzymes and any variants obtained, for example, by genetic engineering techniques. The alkaline polygalacturonase enzymes are produced by alkalophilic microorganisms, for example, bacteria, fungi and yeasts such as Bacillus species. Preferred microorganisms are Bacillus firmus, Bacillus circulans and Bacillus subtilis as described in JP 56131376 and JP 56068393. Said enzymes can also be produced by Eria species. E are preferred. chrysanthemi, E. carotovora, E. amylovora, E. herbicola, E. dissolvens as described in EP 59066588, JP 63042988 and in World J. Microbiol. Microbiotechnol. (8, 2, 115-120) 1992. Alkaline pectin degrading enzymes can also be produced by Bacuillus species as described in JP 73006557 and Agr. Bioí. Chem. (1972), 36 (2) 285-93. Pectin-degrading enzymes are produced by alkaloflucos microorganisms, for example, bacteria, fungi and yeasts such as Bacillus species. Preferred microorganisms are Bacillus firmus, Bacillus circulans and Bacillus subtilis as described in JP 56131376 and JP 56068393. Pectin decomposing enzymes include galacuran-1, 4-alpha-galcturonase (EC 3.2.1.67), polygalacturonase activities (EC 3.2.1.15) pectin esterase (EC 3.1.1.11), pectate lyase (EC 4.2.2.2) and its isoenzymes and can be produced by Erwinia species. E. chrysanthemi, E. carotovora, E are preferred. amylovora, E. herbicola, E. dissolvens as described in EP 59066588, JP 63042988 and in World J. Microbiol. Microbiotechnol. (8, 2, 115-120) 1992. Said pectin enzymes can also be produced by Bacuillus species as described in JP 73006557 and Agr. Biol. Chem. (1972), 36 (2) 285-93. Said enzymes can be used after purification to isolate polygalacturonase enzymes substantially free of another pectic enzyme. Pectic enzyme compositions consisting essentially of polygalactinase enzymes are preferred. At present, it is common practice to modify wild-type enzymes through protein / genetic engineering techniques to optimize their efficiency of performance in the cleaning compositions of the invention. For example, variants can be designed in such a way that the compatibility of the enzyme to commonly found ingredients of said compositions is increased. Alternatively, the variant can be designed in such a way that the optimum pH, bleach stability, catalytic activity and the like, of the enzyme variant is adjusted to suit the particular cleaning application. In particular, attention must be focused on amino acids sensitive to oxidation in the case of bleaching stability and surface charges for the compatibility of surfactant. The isoelectric point of said enzymes can be modified by the substitution of some charged amino acids, for example, an increase in the isoelectric point can help improve compatibility with surfactants. The stability of the enzymes can be further increased by creating, for example, additional salt bridges and promoting calcium binding sites to increase chelator stability.
Dispersants It has surprisingly been found that the inclusion of dispersants, particularly organic polymer dispersants, is of great value in detergent compositions containing polygalactinase enzymes. alkaline The dispersants help the dispersion of the degradation products of the enzymatic degradation of soils, thus preventing their redeposition in articles in the wash. Suitable organic water-soluble salts are homo- or copolymeric acids or their salts, in which the polycarboxylic acid comprises at least two carboxyl radicals separated from one another by not more than two carbon atoms. Polymers of this type are described in GB-A-1596, 756. Examples of these salts are polyacrylates with MW of 2000-5000 and copolymers with maleic anhydride, such copolymers having a molecular weight of 1,000 to 100,000. Especially, in the detergent compositions of the present invention, acrylate and methacrylate copolymers such as 480N having a molecular weight of 4000, at a level of 0.5 to 20% by weight of the composition can be added. The compositions of the invention may contain a lime soap peptising compound, having a lime soap dispersing power (LSDP), as hereinafter defined to be no more than 8 preferably no more than 7, more preferably no more of 6. The lime soap peptizer compound is preferably present at a level of 0% to 20% by weight. A numerical measure of the effectiveness of the lime soap peptizer is given by the dispersing power of lime soap (LSDP) which is determined using the lime soap dispersant test, as described in an H.C. Borghetty and C.A. Bergman, J. Am. Oil. Chem. Soc., Volume 27, pages 88-90, (1950). This method of testing the dispersion of lime soap is used extensively by spatialists in this field of art who are referred to, for example, in the following articles of specialized journals: W.N. Linfield, Surfactant science Series, Volume 7, page 3: W.N. Linfield, Tenside surf. det. , volume 27, pages 159-163, (1990); and M.K. Nagarajan, W.F. Masler, Cosmetics and Toiletries, volume 104, pages 71-73, (1989). The LSDP is the ratio of percent by weight of the dispersing agent to the sodium oleate required to disperse the lime soap deposits formed by 0.025 g of sodium oleate in 30 ml of water with equivalent hardness of 333 ppm of CaC 3 (Ca). : Mg = 3: 2). Surfactants having good lime soap peptising ability will include certain amine oxides, betaines, sulfobetaines, alkyl ethoxysulfate and ethoxylated alcohols. Exemplary surfactants having an LSDP of not more than 8 for use in accordance with the present invention include dimethylamine oxide of C ^ gC ^ g] -2 ~ C] _3 alkylcytoisulfates with an average degree of ethoxylation of 1 to 5, in particular C12-C15 ethoxysulfate surfactant with an ethoxylation degree of about 3 (LSDP = 4) and ethoxylated alcohols of C14-C] _5 with an average degree of ethoxylation of either 12 (LSDP = 6) or 30, sold under the factory names of Lutensol A012 and Lutensol A030 respectively, by BASF GmbH. Polymeric lime soap peptizers suitable for use herein are described in the article by Nagarajan, W.F. Masier, which is in Cosmetics and Toiletries, volume 104, pages 71-73, (1989). Lime soap peptizers, hydrocarbon bleaches such as 4- [N-octanoyl-6-aminohexanoyl] benzenesulfate, 4- [N-nonanoyl-6-aminohexanoyl] benzenesulfonate, 4- [N-decanoyl-] can also be used as lime soap peptiser compounds. 6-aminohexa-noyl] benzenesulfonate and mixtures thereof; and nonanoyloxybenzenesulfonate together with hydrophilic / hydrophobic bleach formulations.

The hydrogen peroxide may also be present by adding an enzyme system (ie, an enzyme and therefore a substrate) which is capable of generating hydrogen peroxide at the beginning and where the washing and / or rinsing process is carried out. Such enzyme systems are disclosed in patent application EP 91202655.6 filed on October 9, 1991. Peroxidase enzymes are used in combination with oxygen sources, for example, percarbonate, perborate, persulfate, hydrogen peroxide, etc. They are used for "bleaching in solution", that is, to prevent the transfer of dyes or pigments removed from substrates, during the washing operations, to other substrates in the washing solution. Peroxidase enzymes are known in the art and include, for example, horseradish peroxidase, ligninase, laccase and haloperoxidase, such as chloro- and bromo-peroxidase. Detergent compositions containing peroxidase are described, for example. in the PCT International Application WO 89/099813, WO 89/09813, and in the European Patent Application EP No. 91202882.6, filed on November 6, 1991, and in EP No. 96870013.8, filed on February 20 1996. Laccase is also suitable. Preferred builders are substituted phenoxyzine and phenoxazine, 10-phenothiazinopropionic acid (PPT), 10-ethylphenothiazine-4-carboxylic acid (EPC), 10-phenothiazinopropionic acid (POP) and 10-methylphenoxazine (described in WO 94/12621), and substituted syringes (substituted C3-C5 alkylsalicylates) and phenols.
