Description

FRGFNTES WITH REDUCED LEVELS OF PEROXTGFNQDO WHITENER CONTAINING A QUELflTRPQR AND ENZII1RS CR? PQ TECHNICAL 5 The present invention relates to detergent compositions containing bleach. In particular, the invention relates to detergent compositions that give effective bleaching performance using higher levels. '' of bleach and bleach activator ..
BACKGROUND OF THE INVENTION The addition of bleach to detergents It is often convenient due to the functional benefits that bleach can provide. For example, • laundry detergents, which contain bleaching! -, provide improved stain removal, cleaning and maintenance of whiteness percudidas. (1) Unfortunately, under certain circumstances, high levels of bleach in laundry detergents will dull the color of the fabrics.The elevated bleach levels in dishwashing detergents, under certain circumstances, may result in ; > 5 problems of tartarity in silver articles. Traditionally, high levels of bleach and bleach levels increase the costs of detergents for consumers. On the other hand, low levels of bleach can lead to defi cient performance. Accordingly, there is a need for detergents which give improved bleach performance, but which contain a low level of bleach. It is an object of the present invention to provide such detergents containing bleach, in a manner described in detail in what follows.
BRIEF DESCRIPTION OF THE INVENTION One aspect of the present invention is the establishment of a biological bleach index (IBB), by which bleach-containing detergent compositions are provided including those formulated for use in -methods for washing clothes and automatic washing c.e tableware, which contain lower levels of bleach and bleach activator with particular levels of chelating agent and enzymes. The detergent compositions of the invention have a biological bleach index (IBB) of nm of 65, when defined by the formula: I BELIEVED [RBIGBPT EBB - 4CC] + 26TE] -. + where: TC] - Chelator level (% by weight) x (number of chelator groups in the chelator)] / (molecular weight of the chelator) x i, 0UÜ; TE] - percentage by weight of enzymes selected from the group consisting of proteases, ilases, raisins, cellulases and their mixtures, in the detergent composition; assuming normal activities of protease J3 KNPU, arnilasa 300 KNU, l pass L65 'u and cellulase 2000 Cevu; CAB] = C (% by weight of bleach activator-) x (a factor of 6 par-a BOBS), a factor of 6 for catimotor activators, a factor of 550 for manganese dinuclear complex activators, and a factor of 4 for all other bleach activators)] / (bleach activator molecular weight) ) x 1,000; and XBP] = (% by weight of peroxygenated bleach) x (% of oxygen available from bleach peroxed) / J00. In another aspect of the present invention, bleach-containing detergent compositions are provided, which contain lower levels of bleach and bleach activator, and higher levels of chelator and, preferably, higher levels of enzymes. In particular, the level of the bleach / activator reduction is represented by the equation: λX = aCX] OJ where "a" is less than 1; the amount of chelator increase is represented by the effect [?] f 2.2 / aCYl "; and the quantity Ldad of enzyme increase is represented by the equation CZ! l / aCZ] 0. This is described in more detail later.
DESCRIPTION DETRLLRDR PE LR INVENTION It has now been discovered, surprisingly, that the higher levels of chelator and enzymes can compensate for lower levels of bleach in a composition.
A tergent. In other words, you can get benefits a. Cleaners for improved stain removal, percussive cleaning and maintenance of whiteness, provided by a predetermined level of bleach, at lower levels of bleach if higher levels of chelator and enzymes are used. i) The iolo bleach induction More particularly, one aspect of the present invention relates to the establishment of a biological bleach index ("IBB") that defines a formula that relates to lower levels of perborate bleach and bleach activator with particular required levels of chelator and of enzymes. According to this aspect of the present invention there is provided a detergent composition containing bleach, which comprises from 5% to 95% by weight of surfactant + detergent; from 0% to 80% by weight of improvement or detergency; from 0.5% to 40% by weight of peroxygen bleach; from 0.01% to 10% by weight of bleach activator; from 0.1% to 10% by weight of chelator; and from 0.05% to 5% by weight of selected enzymes of the group q? e consists of proteases, amylases, lipases, cellulases and their mixtures; wherein the detergent composition has a biological-bleach index ("IBB" of more than 65, as defined by the formula: LAB] CRB1CBP1 IBB 4CC] + 26CE] 320 12 where: CC] - [chelator level (% by weight) x (number of chelator groups in the chelator-)] / (molecular weight of the chelator) x 1,000; LE] = percentage by weight of enzymes selected from the group consisting of pro-teases, to lases, li raisins, cellulases and their mixtures, in the detergent composition; Assuming normal activities of protease 13 KNPU, amylase 300 KNU, lipase 165 KLU and cellulase 2000 Cevu; [AB] = [(% by weight of bleach activator) x (a factor- of 6 pair-to BOBS), a factor of 6 for cationic activators, a factor of 550 for complex dinucleate activators of manganese, and a factor of 4 for all activating bf activators)] / (molecular weight of bleach activator) x 1,000; and [BP] - (% by weight of peroxygenated bleach) x (% of oxygen available from the peroxygen bleach) / 100. The biological bleach index defines a particular relationship between the level of the chelator, the level of the enzymes, the level of peroxygen bleach and level of bleach activator. By following the relationships defined in the formula, compositions can be provided. Airborne agents that contain lower levels of peroxygen bleach and bleach activator, but still give benefits of laundry detergents containing bleach. The detergent compositions according to the invention have a biological bleach index of more than 65, preferably more than 75, and still better than R 0. As seen in the formula, fC] is defined by Ou the chelator- (% by weight) x (number of chelating groups in the chelator)] / (molecular weight- of the chelator-) x 1,000. The number of chelator groups in the chelator is factored into the formula, as a way to factopzar the chelator efficiency of the chelator (ie, it is believed that the chelator efficiency is influenced by the number of those chelating groups). "heady" "chelating groups" is meant, herein, functional groups that have a chelating ability, including, for example, the phosphonate and carboxylate groups. It is to be noted. {; said chelating groups frequently comprise, in solution, oxygen charged above. By way of example, the etiiend aminotetraacetic acid (EDTA) has four chelating groups (carboxylate). Again when seen in the formula, [E] is defined as the percentage by weight of the total enzymes present in the detergent composition, assuming normal activities of 13 KNPU protease, 300 KNU amylase, 165 KLU lipase and 2,000 Cevu cellulase. If the actual activities of these agents in the detergent compositions are different from their normal activities, the CE factor is adjusted accordingly.
For example, protease having an activity of 26 is used.
KNPU instead of the normal 13 KNPU, multiply the factor [E] by 2 to compensate for the extra activity of the enzyme. The same applies to arn lasas, lipases and cellulases. KNPU means kiloNovo units of protease; KNU are units , -i-? loNovo to measure amylase activity; KLU are Normal units defined by Novo to measure lipase activity; CEVU are normal units to measure cellulase activity. Those units of normal activity of the enzymes are well understood by persons skilled in the art. The detergent compositions of the present invention may also include other types of enzymes (e.g., peroxidases or lignases). The factor [AB] in the formula defines the level of bleach activator as adjusted by-a factor-that limits its per-activity. A factor of 6 is assigned for BOBS and for cationic activators; a factor of 550, for the complex activators of manganese di nuclear; and a factor of 4 is assigned to all other bleach activators. Again in the formula, with [BP] the level of peroxygen bleach is adjusted by the percentage by weight of oxygen available from the peroxygen bleach. The percentage by weight of "available oxygen" or percentage of "active oxygen" of the bleaching compounds p roxige os, _. well understood by experts in the field. For example, percarbonates have an available oxygen percentage of 13.5%, perborate rnonohydrides have an available oxygen percentage of 13.5%, perborate monohydrates have an available oxygen percentage of 5.5%, and perborate tetrahydrates Have an available percentage of oxygen of 10.5%. "« ~ In summary [C] is the chelator parameters / 100 g -the detergent, corrected for the number of chelating groups, CE] is the total enzyme level, corrected for the activity level of the enzymes; [AB] is the my bleach activator limolles / 100 g of detergent, corrected for the activity; and [BP] is the percentage by weight of oxygen available from the peroxy bleach.
') Detergent compositions having a reduced biana disinfectant and increased enzymes / enzymes In accordance with another aspect of the present invention, detergent compositions containing bleach are provided, which are defined by a reduction in the level of bleaching agent and an increase in the level of chelating agents and / or enzymes. In particular, a detergent composition containing bleach is provided, comprising from 5% to 95% by weight of rinsing detergent surfactant; from 0% to 80% by weight of detergency builder, bleaching and chelating agent and / or enzymes, wherein the ingredient levels are defined as follows. It has been found that the cleaner benefits are provided for a given amount of CX] 0 of bleach can also be obtained at reduced levels of bleach iX], if -A5® increases the levels of chelating agent TY] and / or is increased The enzyme levels [Z], according to the following cor-relations: CY] * 1 2 / a [?] 0 rz] _L 1 / aCXlo increase of the chelator and co enzyme levels, will result the improved removal of certain stains with respect to the product with high bleach content. In the above formulas, "f" means "final"; that is to say-, L > amounts in the final claimed detergent composition of the present invention, while "o" means "original", ie, the amounts that were present before the reductions / increases according to the present invention. Here [X] is the sum of bleaching agents, by percentage levels in weight in the product, considering 100 percent activity for bleaching agents. The bleaching agents are a hydrogen peroxide bleach or a bleach activator, an organic peroxyacid or mixtures of them. For example, the reduction of bleach can be derived from the decrease in the level of per-oxygenated bleach and / or in the bleach activator, in the detergen-e. TY] is the sum of one or more chelators, in percentage by weight, in the product. The increases in the level and the level can be from the increase in the level of the chelator type present in the product with a high level of bleach (if there is one) or by adding another one (s) of chelator (s) product or both. If the product with high level of bleach, that is,? 0 does not contain any chelator, then it is preferred that Y] * _ >; (CX] 0 - [?] *) / 3. CZ] is the sum of the total of enzymes, in% by weight in the product, assuming enzymatic activities as: Pr-oteases: 13 KNPU Arnilases: 300 KNU (^ Lipolases: 165 KLU Cellulases: 2,000 Cevu. in percentage by weight they can be corrected for other enzymatic activities, such as% by weight of protease (13 KNPU) =% by weight of protease ("P" KNPU) x (P713);% by weight of alase (300 KNU) =% by weight of amylase ("A" KNU) x A / 300); and sirní larrnente for lipolasas and cellulases. Other types of enzymes (eg, peroxidases or lignases), when present, are used for normal activities. Increases in enzyme levels may come from increases in all or some of the enzymes in the high-bleach formula, or by adding different enzymes, or both. In the above formulas, "a" is less than 1 !; CX] 0 is between 3% and 80%; TY] 0 is between 0% and 10% and CZ] 0 is between -n.01% and 10%. Preferably, 0.2 < _ a < l; better- yet, 0.5 j. a < 1; preferably, CY] 0 is between 0% and 3%, and preferably [Z] o is between 0.05% and 5%.

(3) The bleaching agent An essential aspect of the invention is an oxygenated bleaching system. In a preferred embodiment, the bleaching system contains a peroxide compound and an Amino compound, bleach activator. The production of the organic peroxyacid occurs by an in situ reaction of the activator with the hydrogen peroxide, which is provided by the peroxygenated compound. Preferred peroxygen compounds include inorganic perhydrate bleaches. Compositions containing mixtures of a peroxygen compound and a bleach activator, in combination with a preformed organic peroxyacid, are also contemplated. r Peroxyacid compounds The inorganic perhydrate salts are the per-oxygenated bleaching compounds preferred herein. These salts are normally incorporated in the form of the salt of an alkali metal, preferably the sodium salt, at a level of 0.5% to 40% by weight, better still, of 1% to 30% by weight and, still - better still, from 1% to 7% by weight of the compositions. The examples of perhi salts < l? The inorganic salts include the perborate salts, particularly the perborate monoohydrate and the perborate te ahydrate, the per-carbonate, perphosphate, persulfate and persilicate salts. The inorganic per-hydrated salts are usually the alkali metal salts. The inorganic in-hydrated salt may be included as the crystalline solid, without additional protection. However, for certain perhydrated salts, the preferred embodiments of said granulated compositions utilize an iron-coated material that provides better storage stability for the perhydrated salt, in the granulated product. Sodium perborate may be in the form of the monohydrate of the nominal formula aBOaU ^ Os- or the tetrahydrate, NaB0aHa0a.3Ha0. Alkali metal percarbonates, particularly sodium percarbonate, are preferred perhydrates for inclusion in the compositions according to the invention. It has been found that compositions containing percarbonate have a tendency to undesirable formals in the presence of surfactants and water, less than compositions containing perborate. It is believed that this is typically due to the fact that the percarbonate has a smaller surface area and lower porosity than the perborate rnonohydrate.
This surface area and porosity act to promote the co-gel with fine particles of agglomerates. < the surfactant agent and, therefore, do not harm the sumi nor stro. Sodium percarbonate is an addition compound that has a formula corresponding to 2NasC03.3H; 2 ?, and can be obtained- in commerce as a crystalline solid. The percarbonate is most preferably incorporated into said compositions in a coated form, which gives stability to the product. A suitable coating material, which gives a product tability, combines the mixed salt of a sulphate and an alkali metal carbonate, soluble in water. Said coatings, together with the coating processes, have been described in GB-1,466, 99, issued by Tnterox on March 9, 1977. The weight ratio of the mixed salt coating material to the per-carbonate remains in the scale from 1: 200 to 1: 4, better still, from 1:99 to 1: 9 and, even better, from 1:49 to 1:19. Preferably, the mixed salt is sodium sulfate and sodium carbonate, having the general formula "aa O ^ .n-NaaCOs, wherein n is from 0.1 to 3, preferably n is from 0.3 to 1.0 and, better still , is from 0.2 to 0.5. Other coatings containing silicate, (alone or with borate salts or boric acids or other inorganic substances), waxes, oils, fatty soaps, may also be advantageously used with the present invention. The potassium peroxyphenol potassium peroxide is another inorganic salt that is used in the detergent compositions herein.

Test method - The opaqueness of the color of the fabric The "fabric color opaque" operation of the three compositions (comparative A and B and example 1) was compared in tests on a full-scale washing machine, using Miele 698 washers. The short wash setting (temperature - 40) was used. ° C) and water was used at 25 °, Germ n hardness (Ca: Mg = 3: 1). For each type of product the laundry load consisted of a single sample of purple wool fabric (sensitive to bleaching) of 43 x 43 crn, and a ballast load of 2 white sheets. Before starting the first complete washing cycle, the washing load was placed in the tub of the washing machine together with a dispensing device of the "granulette" type containing 75 g of the detergent product. The purple wool sample was placed in such a way that it was adjacent to the dispensing "mouth" of the granulette. After the first revolution of the short wash cycle, a stopwatch was started. The cycle was interrupted after 10 minutes from this time and the laundry load was removed from the tma. The purple wool sample is dried before any color opacity is determined in the wool sample being treated. -or The above procedure was repeated four times for each type of product, each time using a sample of fresh purple wool.
Determination of Color Opacity The darkening or loss of the color of the four samples of purple wool obtained from the internal procedure, for each type of product, was determined by a panel of experts, using as reference a sample of unwashed purple wool.
