HYPOCHLORITE CLEANSERS WITH UNPLEASANT SMELL OF REDUCED SKIN FIELD OF THE INVENTION The present invention refers to com on i ci ne1. hypoclop + o cleansers that include midodisul fat ?, potion toy optionalrnen »e a9eni.es surfactants, improved detergents, perfumes, abrasives and / or 0+ ros vehicles and auxiliary materials that evok so the unpleasant smell odor of the skin when said composition makes contact with human skin. The present invention also relates to a method for cleaning hard surfaces with a composition comprising hypochlorite and hydrosulphite which reduces the formation of unpleasant odor in human skin.

BACKGROUND OF THE INVENTION Hard surface cleaners may be in liquid, solid or viscous semi-solid form. The known liquid, solid and viscous viscous hard surface cleaners may comprise detergent agents, detergent, water and optionally some organic solvents, better detergent, pH regulators and / or perfumes as well as other auxiliary materials. The solid shapes and viscous solids of hard surface cleaners may optionally comprise one or more abrasive materials as auxiliary ingredients. Hard surface cleaners and solid viscous solids containing abrasive materials are primarily used as "water repellent" agents. It has long been known that abrasive materials can be used in conjunction with hard surface impurities to remove soiling or creams from commonly used soap. The inclusion of hi tion and hypochlorite generating components in surface cleaners hard has been increasing steadily. In fact, hard surface cleaners that contain hypochlo- pt are among the effective cleaning materials since the solution does not look as much like a strong oxidant as it does to help in the chemical degradation, breakage and removal of stains. and dirt, and also as an effective and low-cost disinfectant. This double function of h? Potion to (as a bleach and disinfectant) along with its storage stability and com bility with other optional ingredients has contributed to the increased use of sodium hypochlo- prate or other active chlorine precursors, in the formulation of surface cleaners. hard. Sinks and washbasins, bath tubs, barium rooms, toilets and cupboard surfaces, including vinyl, acrylic and marble, are areas that have been focused for development on the increased cleaning capacity of hard surfaces. These hard surfaces are subject not only to exogenous bacteria, fungi and molds endemic to most homes, but also to pathogens that are derived from urine and feces. Therefore, the inclusion of hypochlo- to in these formulations as a strong and versatile de- fectant is an added benefit to consumers. To ensure proper hygiene and sanitation conditions, a formidable cleanup task must be performed to remove undissolved sediments, grease, soap films, creams, hard water scale and stains that form on the surface.

If) ceramic surfaces, upper surfaces of dressers and bathroom floors during normal use. Cleaning is especially difficult in the case of hardened and dried soap films, creams, cake-shaped debris and grittings due to hard water / undissolved dirt where it is It is necessary to use more than simple cleaning with a cloth to remove unwanted slow thirst. During the use of hard surface liquids that contain hi pool opto, the contact of the cleansing solution, containing active chlorine, with the human skin results the production of unpleasant odor in the skin known as odor- "hand with bleach-". The smell of "anus with bleach" is believed to result from contact between the hypochlorite bleach and the protein in the skin differs from the "chlorine odor" of the hipoelopto bleach as such. Market Stall ')! .- that the active ingredients of hard surface cleaners, especially hypochlorite bleach, can not be distinguished between dirt, utensils and exposed human skin during the scrubbing procedure, the only protection for the time being Use of gloves. It has now been found that the inclusion of iodinated fats in such bleach with h poclopto reduces the unpleasant odor-forming induced by chlorine on the skin. The present invention, by virtue of its effect on the unpleasant smell odor derived from sunlight or sun exposure, avoids the need to wear gloves or other protection of the exposed skin during cleaning. It also protects against inadvertent spatter of the solution on the skin such as that of the face, neck, legs, forearms, etc. Also due to the action of the imidodisulfate of the present invention, exposure of the fabric to the direct solution is not as harmful as direct exposure to hypochlorite. Therefore, it is an object of the present invention to prevent the formation of unpleasant odor in the skin due to exposure to hypochlo- pho. Another object of the present invention is to provide a hypopellent-containing cleaner that prevents the formation of unpleasant odor on exposed skin. Another object of the present is to provide a cleaning composition that will contine inidodisui fat o.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a hard surface cleaning composition comprising hypochlorite, iridium sulfate and the rest auxiliary ingredients, which, when in contact with the skin during use, avoid the unpleasant odor on the derived skin. of the hypochlorite. These compositions can be solid, viscous or liquid serrulose. In its broadest aspect, this invention involves a method of cleaning hard surfaces that eliminates the formation of unpleasant odor on the skin derived from active chlorine or hypochlorite also known as "anus with bleach" odor. A cleaning solution containing uni-odulose and hypochlorite is applied to a hard surface to remove any dirt, grease, oily dirt, soap deposits or soap films, and any intentional, accidental or incidental contact of said cleansing solution with the skin human does not give rise to the formation of oloi unpleasant. The hard surface cleaners of the present invention comprise imido disulfate of the N (c,? 3M) 2 form wherein M is a hydrogen or a water soluble cation and mixtures thereof, preferably M is hydrogen or a cation which is a member selected from the group consisting of the alkali metals or metals to the lime and the earth, or preferably M is sodium or potassium. The hard surface cleaner of the present invention comprises a blend of from about 0.05% to about 50%, preferably from 0.1% to about 20%, most preferably from about 0.5% to about 10%, highly preferred. Even from about 0.5% to about 5% by weight of the composition. The present invention comprises hypochlo- pet that can be derived from any normal hypochlo- phocyte material that is normally used as a bleach or disinfectant, and does not bind to sodium hydrochlorite. The hard surface cleaner of the present invention contains hypoelopte of from about 0.1% to about 25%, preferably from about 0.1% to about 20%, and preferably about 0.5% to about 10%, u and pr-e Silver, even from around 0.5% to 5% by weight of 1? composition.

The present invention optionally comprises detersive surfactants, detergent builders, abrasives, pH regulators, perfumes, solvents and other suitable auxiliary ingredients used alone or in combination which the developer may find useful in the practice of the present invention. The present invention provides a method of cleaning hard surfaces with a composition comprising imidodisulphate, hypochlo- pt and option and above-mentioned auxiliary ingredients. This method comprises contacting by scrubbing or brushing a surface that needs to be cleaned with a cleaning composition with the present invention. All percentages, ratios and proportions herein are by weight, unless otherwise specified.

All temperatures are in degrees centigrade (° 0) unless otherwise specified. All the cited documents are, in an important part, incorporated here by reference.

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method of cleaning hard surfaces with a composition comprising iodide, hypochlorite and surfactant wherein said cleaning composition is applied directly to a dirt, stain, cream or other material to be cleaned and the user applies Mechanical scrambling action .. "Egressed" filler is achieved by contacting a cleaning device with the dirt, stain, cream, or other soiled surface and cleaning composition of the present invention; and the cleanser containing hypochlo- phot, when it makes contact with the fingers, hand or other exposed surface of the user's skin, whether by direct contact or splash, will not produce an unpleasant odor. In addition to the uni dodisul fato and ipoclopto, the hard surface cleaning compositions of the present invention will typically comprise detersive surfactants and other adjuvant ingredients. What is meant by contacting the poclorite solution of the present invention with the dirt, cream, stain or other object or surface to be cleaned in i < The present invention does not refer to the application of the composition directly to the object to be cleaned, but rather the composition can be applied to a sponge, pad, brush, cloth or other device normally used to facilitate the contact of a cleaning composition with the area to be cleaned. What is meant by contacting the hypochlo- mous solution of the present invention with human skin is splashing on the surface of the skin, immersion of the hand, arm or other part of the body in a solution that contains the composition of the present invention, either accidentally or intentionally, especially in the normal course of cleaning. The tissue of the eye is excluded as is the tissue of the mouth. The safe, secure, and intended protection against the unpleasant odor of the hypochloc- ical cleansing solution of the present invention excludes the exposure of the composition to the eyes, mouth or other internal organs including cuts, injuries or other Ruptures in the skin normally not exposed during the common use of cleaning solutions. The invention of the present invention, especially in solid and viscous semi-solid forms, need not be present in a quantity necessary to avoid the unpleasant smell on a base of estequiornetpa or another chemical theory. Excess imido disulphate can serve as a mechanical abrasive, such as perlite and carbonate, and thus allow the fornulator the option of excluding additional ingredients when an abrasive is needed. Also the iridodisulfate can be used in excess to serve as a detergent enhancer or a "hard" cation chelator, ie, calcium and magnesium, and thus offer an "increase" to the surface activity of any surfactant agents. Detersive agents that may be present in the selected modality. Although it is not intended to limit the theory, the main component of unpleasant odor to "hand co-bleaching" on the skin is 1-p? rol? na. This material is formed from the amino acid L-proli a when the keratin protein found in the stratum corneum layers of the skin is exposed to hypochlo- phocyte. The rate of formation and the amount of 1-pyridine that forms vain from one individual to another but the general mechanism of formation is believed to be universal. The degradation of skin protein is thought to begin with the rapid and irreversible chlorination of an amide bonding protein when the skin is exposed to solutions containing hypochlo- phate. If this N-chlorination occurs adjacent to the L-proim amino acid, protein fragmentation results in 1-pyrrolma formation. The rate of degradation of rotates, once N-chloraeion has occurred, is variable from one individual to another and, in some cases, the formation of odor-unpleasant on the skin continues for several days after exposure to hypochlop. . It has now been found that the inclusion of itni dodLsul t in cleansers with hypoclop or reduces the formation of unpleasant odors induced by active chlorine on the skin. The inclusion of iridodisulphonate in solid hard surface cleaners or solid viscous hypochloride may have an additional function other than that of unpleasant odor control. The solid immisole or the appropriate salt can be formulated in a hypochlorite containing a solid or viscous semi-solid component to serve as a water-soluble abrasive.

The hard surface cleaner is presented with an optional invention containing detergency builders, examples of which are silicates, carbonates and zeolites; however, the user is not limited to these examples or combinations thereof, the detorgency speakers are present in an amount of about 0% to about 50%. preferably from about 5% to about 30%, by weight of the composition. The hard surface cleaner of the present invention optionally contains abrasives of about 0.5% to about 85%, preferably from about 10% to about 85%, by weight of the composition. Suitable abrasives are silicates, carbonates, perlite, clay and pulverized ceramic clay; however, the user is not limited to these examples or combinations thereof.

AUXILIARY MATERIALS The compositions of the present optional may include one or more detergent auxiliary materials to help increase the cleaning performance, treatment of the surface to be cleaned, or modify the aesthetics of the composition (e.g., perfumes, dyes, dyes, etc.) .. The following are illustrative examples of said auxiliary materials but are not intended to be exclusive or limiting in scope. .1.2 Surfactant - The present cleaning compositions contain from about 0.1% to about 0% by weight of a surfactant selected from the group consisting of ammonium, nonionic, ampholytic and zyotonic ionic surfactants. For liquid systems, the surfactant is preferably present to the degree of about 0.1% to 20% by weight of the composition. For solid (ie granulated) and viscous (ie gelatinous, paste, etc.) solid systems, the surface active agent is present to the extent of about 1.5% to 30% by weight of the composition. The ammonium surfactants can be broadly described as the water-soluble salts, particularly the alkali metal salts, of organic sulfuric reaction products having in their molecular structure an alkyl radical containing from about 8 to about 20. carbon atoms and a radical selected from the group consisting of sulphonic acid ester and sulfuric acid ester radicals. (In the term alkyl, the alkyl portion of higher acyl radicals is included). Important examples of the synthetic ammonia detergents that can form the surfactant component of the compositions of the present invention are the sodium or potassium alkyl sulphates, especially those obtained by sulfation of the higher alcohols (8--18 carbon atoms) produced by reducing the glycerides of tallow or coconut oil; sodium or potassium benzene sulphonate, in which the alkyl group contains from about 9 to about 15 carbon atoms (the alkyl radical can be a straight or branched aliphatic chain); alkyl glycol ether estersulfonates, especially those ethers of higher alcohols derived from tallow and coconut oil; sulphonates and sulphonates of inorganic fatty acid of coconut-sodium oil, - sodium or potassium salts of sulfuric acid ester of the reaction product of one mole of a fatty alcohol supeí jor (v.gr,., tallow alcohols or coconut) and from about 1 to about 10 moles of ethylene oxide; Sodium or potassium salts of alkyl ether sulphide ether sulfides with an amount of approximately 1 to about 10 units of ethyl acetate per molecule and in which the alkyl radicals contain from 8 to 1? carbon atoms; Fatty acid reaction products are derived from sodium or potassium salts of coconut oil fatty acid amides of an amino acid in which the fatty acids, for example, are derived from coconut oil and beta-acetoxy. or beta -acetami or-alcansul sodium or potassium phonates' where the alkane has from 0 to 22 carbon atoms. In addition, those to which secondary particles can be used by the fornulator alone or in conjunction with other surfactant materials and the following iden tify and illustrate the differences between sulfated surfactants and conventional alkyl sulfate surfactants.

Non-limiting examples of these ingredients? 'On the s i gu i en t e,. Conventional primary primers, such as those illustrated above, have the gene formula R0 03-M + where R is typically a linear hydrocarbyl group of C8-22 and M is a sun-soluble water cation. . LVOS or alkylsulfat or branched chain prodrugs (ie, branched-chain "PAS") having 8-? 0 carbon atoms are also known; see, for example, European Patent Application 439,316, rnith et al., filed January 1, 1991. Conventional secondary alkylsulfide agents are those materials that have the sulfate portion randomly distributed to along the hydrocarbyl "base structure" of the molecule. These materials can be illustrated by the structure OH3 (OH2) n (CH0 03-M +) (CH2) K1CH3 where m and n are enter-os of? or y and the a of rn * n is typically from about 9 to 17 and M is a sun cation ubiliible in water. In addition, the selected alkyl sulfate or secondary (2,3) surfactants used here can comprise-structures of formulas 1 and TI 0H3 (0H2) x (CHO3-M +) CH3 I CH3 (CH2) and (CHOSO3-M +) 0H2OH3 II for 2-sulfate and -sulphates respec tively. Mixtures of 2- and 3-sulfa < or they can be used in the present. In formulas 1 and II, x and i and + 1) are speci fi cally monkeys of about 7%, and can vary around 7? about 20, preferably from about 10 to about 16. M is a cation, such as an alkali metal, ammonium, alkanolarnonium, tp and anolaronium, potassium, ammonium and the like can also be used. The aforementioned secondary alkyls are those prepared by the addition of H2O4 to the fine ole. A typical synthesis using alpha-olefins and sulphuric acid are described in the U.S. Patent. No. 3,234,258, Morris, issued February 8, 1966, or in the U.S. Patent. No. Lutz, issued December 24, 1991. The synthesis conducted in solvents that gives the secondary agents (2,3), upon cooling, gives products that when purified to remove non-reactive materials, materials Randomly bound, unsulfated by-products such as CIO alcohols and higher, secondary olefin sulfonates and the like, are typically mixtures 90 +% pure materials 2- and 3-sulphated (some sodium sulfate may be present) and are non-sticky white solids, apparently crystalline. Some 2,3-disulphonates may also be present, but generally it comprises no more than 5% of the mixture of the secondary ones. (2,3). These materials are available under the name "DAN" eg, "DAN 200" from Shell Oí 1 Company. PH regulators - pH regulators can be included in the formulas herein for a variety of purposes. One such purpose is to adjust the pH of the cleaning surface to optimize the effectiveness of the hard surface cleaning composition in relation to a particular type of dirt or stain. Pn regulators can be included to stabilize the auxiliary ingredients with respect to prolonged storage life or for the purpose of maintaining compatibility between various aesthetic ingredients. The hard surface cleaner of the present invention contains pH regulators to adjust the pH in the range from about 7 to about 13, preferably from about 8 to about 13, and preferably from about 8 to about 13. about 10 to about 11. Non-limiting examples of such suitable pH regulators are potassium carbonate, sodium carbonate and sodium bicarbonate; however, the formulator is not limited to these examples or combinations of the same. Chelating Agents - The cleaning compositions herein may also optionally contain one or more iron and / or manganese chelating agents. Examples of such compatible chelating agents are ethan-1-hydroxy-1 acid, 1-d? Phonic phosphide (EHDP) and acid di pico! monkey. Abrasives - An essential component of many solid or viscous solid viscous cleaning compositions for hard surfaces is the abrasive material added to facilitate scrubbing action. Abrasive scouring cleaners provide convenient and useful means for cleaning porcelain and tile surfaces, especially bath tubs, bathrooms and toilets. The particulate abrasive material within said compositions is used to abrade- and weld adherent dirt to hard surfaces and also to create a more intimate contact between a hard surface stain and surfactants and / or bleaching agents. also present in cleaning compositions. Abrasive cleaners traditionally have relatively hard, water-soluble particulate mineral content contained in the abrasive agent. The most common abrasive agent in finely divided silica sand having a size ranging from about 1 to 300 microns and a relative density of about 2.1 or greater. Although said material is generally very effective in recovering dirt and stains from the surfaces being treated, abrasive material of this type tends to be difficult to remove from the surface of the toilet, bathroom or bath tub. In the case where moderately or highly water-soluble abrasive material (ie, sodium carbonate) is required, the only abrasive or otherwise partially added can be used.

GO It has been discovered that abrasive compositions of this desired type can be made using a particular type of expanded perlite abrasive in combination with the surfactants, filler material, and other optional reagent material ingredients listed herein. The abrasive materials suitable for the present invention are those contained in the U.S.A. No. 4,051,056, Har-tman, issued September 27, 1977 and included herein by reference. 10 Perfumes - Perfumes are an important ingredient especially in the form of liquid composition. Fl perfume is generally used at levels of 0% to 5%. In the patent of E.U.A. No. 4,246,129, Kacher, issued January 20, 1981 (incorporated herein by reference), describes certain perfume materials that perform the additional function of reducing the solubility of ammonium surfactants of their phonat and their fate. Other auxiliary ingredients Co or a preferred embodiment, the conventional auxiliary ingredients here They can be selected from bleach stabilizers, pigments, colored dots, foam mixers, foam suppressors, rust and / or anti corrosion agents, soil suspending agents, germicides, alkalinity sources, hi rotropes, ant? ox? dantes, agents of ' !: r-ernocion / ant iredeposition of clay dirt, polimépcos dispersing agents, etc.
