Description

09093321. 050899 163.1246US01 PATENT COMPOSITIONS AND PROCESS TO CLEAN AND FINISH SURFACES DURAS Field of the Invention The invention relates to finishing cleaning compositions for hard surfaces. A finishing cleaning composition is a composition that can be applied to a hard surface in order to obtain a surface free of residues, shiny, clean without the operator having to rub or dry after cleaning. The compositions of the invention can be applied to remove dirt and then dry to obtain a clean, glossy, glossy appearance. The finishing cleaner can be used alone or with other compositions. In a preferred mode the finishing cleaner is applied after a first cleaner is used and the cleaner removes all residual residue and dirt leaving a glossy surface transparent without the need to clean or polish the surface. BACKGROUND OF THE INVENTION In institutional, industrial and hospital industries, cleaning hard surfaces such as metal, painted metal, glass and tile is a labor-intensive activity. Such surfaces are commonly found in kitchens, bathrooms, places for food preparation and manufacturing, fast food restaurants, cars, etc. Commonly, to clean such surfaces maintenance personnel apply an aqueous cleaning composition to the surface in a foamed or non-foamed aqueous composition. The dirt is then mechanically contacted with the cleaning brushes, cleaning towels and other cleaning implements. Dirt from the cleaning material is rinsed and the remaining rinse water is often removed by mopping brushing or by other processes in which the maintenance staff removes the remaining puddles of water. The final cleaning / brushing step is important to ensure that the hard surface dries to a lustrous, shiny, stain-free, scratch-free, film-free appearance. In facilities that have many hard surfaces in which periodic cleaning is required on a daily, weekly basis, etc., it is important to invest in labor, energy and cost. Any reduction in time, energy and materials used in hard surface maintenance will substantially improve productivity and reduce costs. An important step in the maintenance of hard surfaces is the final mopping or brushing of hard surfaces to remove the aqueous rinse. These operations can consume a substantial proportion, normally between 10 and 30% of the time involved in the maintenance of hard surfaces in most institutional, industrial, and hospital locations. The elimination of the final brushing / mopping step can obviously save time, effort and substantial cost. In the maintenance of normal hard surfaces, the final mopping / brushing step is required. No cleaner currently available provides the simple spraying application that dries a shiny, clear, glossy surface without leaving stains, scratches or developing film. There is a substantial need for such a finish cleaner that can be used alone or with other cleaners to remove dirt from hard surfaces leaving a lustrous appearance, without spots, streaks or film. In the prior art, attempts have been made to use modified silicones, hydrophobic mineral oils and other hydrophobic media to increase the tendency for aqueous materials to drain from a clean surface. We have found that hydrophobic materials surprisingly increase surface energy and retain water as droplets of various sizes instead of causing the water to spread or drain freely. To use such hydrophobic materials, cleaning stations such as car washes have to use forced air to crash and remove the droplets or to remove the drops using suede, mops or towels. The Patents of E.U.A. Nos. 5,536,452 and 5,587,022 from Black teach a spray material after the shower that is formulated to maintain a shower appearance. These materials do not operate as a finishing cleaning composition and are simply formulated to reduce the accumulation of dirt in a shower. The compositions contain a specific surfactant and volatile cleaning materials to promote drying. Consequently, there is a substantial need for improved cleaning compositions and in particular for a finishing cleaning composition that can be used after an initial cleaning step which, after of a spray application can be dried until it has a clean, shiny, glossy appearance, without residues of stains, scratches or films. Such a cleaner can save significant time and money and can improve the appearance of hospitals. Brief Discussion of the Invention The finishing cleaning compositions of the invention have application in the cleaning process using both acidic and alkaline cleaners containing an aromatic sulfonate, a sulfosuccinate and a nonionic defoamer. Such cleaners have a pH value ranging from about 1.5 to about 11. The cleaning compositions may contain acidic or basic components, anionic or nonionic surfactants, chelating agents. water hardness modifiers, organic or inorganic binders, fragrances, surfactants, dyes, solvents and other conventional ingredients. Cationics are not compatible with these cleaners. Under certain circumstances for particular end uses, if necessary, threshold agents or antimicrobial agents can be incorporated in the rinse product. In order to develop the compositions of the invention we have found that the common rinse aid or expansion materials used in the cleaning do not provide adequate expansion at room temperature on hard hospital surfaces common to economical levels of use. The combination of ester sulfonate and the aromatic sulfonate of the invention at a surprisingly low concentration obtained excellent final cleaning and drying effect. The addition of defoaming surfactants with low specific foaming results in the creation of a foamed composition with the finish cleaners in the invention that does not foam or produce a weak foam that is easily separated to a material that extends and drains of the surface quickly leaving a clean appearance. Surprisingly, the finishing cleaning compositions of the invention quickly remove the still heavier working formulations containing high concentrations of active materials and associated dirt residues from hard surfaces that leave no residue of the cleaner or dirt on a lustrous, free surface of spots or streaks. In contrast, current cleaning compositions, while effective in removing dirt, can often leave residues of stains, streaks or film that can not be seen on hard surfaces even after significant effort to remove dirt on a surface. cleaning regime. We have also found a unique cleaning process that can produce a hard surface, clean, shiny, glossy, free of stains, scratches or film, resulting from a regime that contains at least two steps of the process. In the first step of the process, a hardener of hard surfaces is applied to a soiled surface to loosen and substantially remove the dirt residue from the surface. The first hard surface cleaner is followed by a finisher that can be surface-water-repelled for all-s and e! residueof cleaner leaving a clean surface, shiny, glossy, without spots, without streaks and without film. The finishing cleaner can be used in a single step to clean surfaces with minimal to moderate dirt. The Finishing Cleaner combines a unique blend of surfactants with an aqueous base with solvents in an optimized formula that can be sprayed on a hard surface and can leave a clean surface without investing a significant amount of effort to clean the surface after the application of Finished cleaner. By avoiding intensive labor, the step of mopping the hard surfaces represents significant savings in time and money. The finishing cleaning compositions of the invention comprise an aqueous based cleaner comprising a sulphonate ester surfactant of the formula wherein each R2 or R4 comprises an aliphatic group of C? .2o, preferably of C- ,. 2 and R2 is H +, an alkali metal cation, NHJ. or a cation of mono-, di- or triethanolamine. The cleaner may also contain a second aromatic sulfonate surfactant agent which comprises a variety of aromatic sulfonate surfactants. Preferred aromatic sulfonate surfactants include alkyl benzene sulfonates, alkylnaphthene sulfonates, dialkyl benzene sulfonates such as xylene sulfonate, petroleum sulfonates made by sulfonating highly aromatic food raw materials or other sulfonates with amide ester or ether ligation. A particularly preferred sulfonate in the invention comprises an alkyl diphenyl oxide disulfonate material. Said materials are made by sulfonating an alkyl diphenyl oxide material. The final sulfonate product comprises a sulfonate material containing mono- and disulfonated species. The preferred sulfonate material generally corresponds to a composition generally described by the formula: wherein Ri is an aliphatic group of C? -? 2 and each R2 independently can be H +, an alkali metal cation, NH4 + or a cation of mono-, di- or triethanolamine. These surfactants cooperate to ensure that the remaining dirt and cleaner on the hard surfaces are removed effectively. This mixture of surfactants is combined with a non-ionizing defoaming surfactant agent which promotes the rapid expansion of the skin. Finishing cleaning composition. The aqueous finishing cleaning composition additionally comprises a water soluble solvent material that aids in the removal of dirt and promotes the drying of surfaces due to the volatile nature of the solvent material. Preferred solvents comprise mono-, di- and triethylene glycol, mono- and dialkyl ethers and alkanols. The invention also contemplates concentrated materials comprising a dilutable composition containing appropriate amounts of said component in the form of a material that can be added to water to form a highly effective aqueous finish cleaning composition of the invention. The finishing cleaning composition of the invention is usually sprayed on a moderately soiled surface or a hard surface which has already been contacted with another aqueous cleaning composition. The spray process step usually forms a film or foam comprising the finishing cleaning material. The foam decomposes rapidly to form a continuous wet spread that drains quickly from the surface and dries even on cold surfaces. At common hospital temperatures, mirror surfaces, toilet surfaces, tubs, and washbasins may be cold and shipped and often resist expansion. We have found that the unique formulation of finishing cleanser of the invention provides subsequent expansion action to leave a lustrous surface without staining. The initial moderate to low foam is an important property of the inventive finishing cleanser to provide for the removal of the cleansing agent. Initial hard surfaces and ensure that the collapse of the complete foam for expansion occurs. We have found that the finishing cleaner of the invention is useful for hard hospital surfaces but can also be used in glass, rubber, painted metal, etc., or other surfaces such as automobiles, etc. Any hard surface such as glazed tile, glass fiber coated with gel, chrome, glass, marble, porcelain, painted metal, etc., can be cleaned with the finished cleaner of the invention. Detailed Discussion of the Invention The finishing cleaners of the invention can be used in a process for cleaning hard surfaces in which a first cleaner can be applied to the hard surface to remove coarse dirt and the finish cleaner can be applied to remove any dirt residue and any residue from the cleaner. After the application, the finish cleaner drains from a surface leaving a clean surface free of stains, scratches or dirt films or cleaner components. Aqueous cleaners for hard surfaces have been available for many years in cleaning, domestic and institutional settings and are exemplified below. Such cleaners have developed the ability to remove organic and inorganic soils including food residues, soap coating, grease, hardness, hair, bathroom waste and the like from hard surfaces. Both neutral, acid and basic aqueous materials have been used depending on the site of use and the type of dirt. Commonly, the cleaners comprise a major proportion of the solvent such as water or mixed aqueous / organic solvent and components such as chelating agents such as EDTA, NTA and others, ammonium and non-ionic and cationic surfactants, disinfectants, fragrances, dyes, solvents, Foaming agents. These cleaners have been known to act appropriately on many soils, however, in certain applications and with certain soils, the use of these cleaners may require a step of extensive rinsing and mopping to ensure that no visible residue remains on any surface lasts after use. These residues can arise from the remaining dirt, the residual cleaning material, hardness components or any other common material in the environment. In the absence of a final rinsing and mopping, hard surfaces can remain with spots, streaks or films that are not easily seen and require cleaning. In the current management of hospital sites including hotels, cruise ships, hospitals or other places that house a large number of individuals with bathroom facilities that have mirrors. toilets, tubs, toilets, sinks and other suitable items, cleaning and maintenance of such facilities are time consuming and expensive. The hospital administration has learned that cleaning facilities for comfort in hospital settings is a major cost and represents a major investment of effort for maintenance. Any composition or product that reduces costs and saves time in maintenance of such hospital facilities can be a significant cost savings and increase in attraction and comfort for the hospital setting. The finishing cleaning compositions of the invention can be formulated with an aromatic sulfonate surfactant or an alkyl dif difyl oxide disulfonate of the formula: wherein R is an aliphatic group of C ^^ and each R2 independently can be H +, an alkali metal cation, NH or a cation of mono, di- or triethanolamine. The sulfonic acid portions of the above formula of molecules show a structure of disulfonic acid. The commercial products that refer to said material comprise a complex mixture of mono- and disulfonates, mono- and dialkylates and alkali metal sulfonate salts thereof. Accordingly, the above formula is a general guide for the use of said aromatic monodisulfonate materials. Suitable commercially available aromatic surfactant surfactants include the DOWFAXf series from Dow Chemical and the POLITERGENT * series from Olin Corporation. The finishing cleaning compositions may also contain an ester sulfonate surfactant of the formula: wherein each R3 and R are independently an aliphatic group of C? -20, preferably of d.2o and R2 is H +, an alkali metal cation. NH4 +, or a cation of mono-, di- or triethanolamine. Such materials are usually termed dialkyl sulfosuccinate ester surfactants. The finishing cleaning compositions of the invention may also contain a nonionic surfactant that can modify the foaming properties of the material to result in a spray material that develops low foaming properties. The low foam generated when applied quickly collapses to leave an extension that is removed by the surface by the action of gravity and rapid drying. The resulting surface is left glossy, without spots, streaks and film. For the appropriate activity, the finishing cleaners of the invention comprise a nonionic defoaming agent that allows the formation of foam which is weak and collapses rapidly, leaving an aqueous composition which It is quickly removed from the surface by the gravity reaction. Such nonionic surfactants are common. A preferred nonionic surfactant comprises acetylene glycol surfactants substituted with nonionic polyoxyethylene. Said compounds of this type are described in the Patent of States United No. 3,855,085. Said polyoxyethylene compounds are commercially available under the general commercial designation SURFYNOL3 by Air Products and Chemicals Incorporated. Examples of such specific polyoxyethylene acetylene glycol surfactants include molecules having from 1 to 20 moles of ethylene oxide which are reacted with 1 mole of acetylene diol such as 485 / as tetramethyldecinodiol. SURFYNOLV is the product obtained by reacting 30 moles of ethylene oxide with a tetramethyldecinodiol. Other examples of acetylene glycol surfactants include 2,4,7,9-tetramethyl-5-decino-4,7-diol, 3,6-dimethyl-4-octino-3,6-diol and 3, 5-dimethyl-1-hexy-3-diol. Examples of such materials include SURFYNOL3 104, 82, 465, 485 and TG. The amount of acetylene glycol surfactant used in the compositions of the invention generally ranges from about 0.1 to about 10% by weight or preferably from about / 5 to 5% by weight depending on the level of foam desired. A p -subferred tertiary agent comprises SUR ~ NOL '"504.

In addition, nonionic surfactants include those available from BASF Wyandotte Corporation of Wyandotte, Michigan under the designation PLURONIC® and TETRONIC®. The surfactants of PLURONIC3 have the formula: (EO) x (PO) and (EO) z; wherein EO comprises an ethylene oxide residue, each PO comprises a residue of propylene oxide, each x is an integer from about 2 to about 128, each y is an integer from about 16 to about 67 and each z is an integer from about 16 to about 67. Useful surfactants have the general formula: (PO) x (EO) and (PO); wherein each EO comprises a residue of ethylene oxide; each PO comprises a residue of propylene oxide, each x is an integer from about 7 to about 21, each y is an integer from about 4 to about 136 and each z is a number from about 7 to about 21. Another class of useful surfactants has the general formula: N-CH2-CH2-N / \ (EO) and (PO) x (PO) x (EO) and wherein each EO comprises a residue of ethylene oxide, each PO comprises a residue of propylene oxide, each x is an integer from about 4 to about 3 and each y is an integer from about 3 to about 122. Another class of useful surfactants has the general formula: (PO) x (EO) and (EO) and (PO) x \ / N-CH2-CH2-N / \ (PO) x (EO) and (EO) and (PO) x wherein each EO comprises a residue of ethylene oxide, each PO comprises a residue of propylene oxide, each x is an integer from about 8 to about 30 and each y is a number from about 1 to about 124. The designation "R" refers to inverse nonionic surfactants. Such nonionic surfactants are formulated to be compatible with the aqueous formulation and to produce a foam that rapidly collapses. The compositions of the invention also contain a soluble or miscible aqueous solvent material. Such solvents may include lower alkanols including methanol, ethanol, isopropanol, propanol, ethylene glycol, propylene glycol, ethylene glycol mono- and dialkyl ethers, propylene glycol, mono and dialkyl ethers, diethylene glycol, ethers of mono- and dialkyl, etc. The solvents may comprise compounds of the formulas: R < R OH and mixtures thereof. wherein R5 and Ra are independently H or a linear or branched aliphatic group of C1-8, preferably alkyl groups, R6 is H or CH3 and x comprises in integer from about 2 to 5. Representative examples of useful solvents include methanol, ethanol, isopropanol, ethylene glycol, monomethyl ether, ethylene glycol monobutyl ether, 2-phenoxyethanol, ethoxy ethyl acetate, 2-ethoxyethanol, ethylene glycol monoethyl ether and other known water-soluble or miscible solvents. These solvents help to remove dirt, control foam and promote drying after mopping. We have found that sequestrants, chelators or water conditioning agents are useful in the compositions and processes of the invention. The removal of dirt is improved by binding Ca2 + residues. The sequestrants work to inactivate the hardness of the water and prevent the calcium and magnesium ions from interacting with dirt, surface active agents, carbonate and hydroxide. Water conditioning agents therefore improve detergency and avoid long-term effects such as insoluble dirt deposits, the accumulation of minerals and mixtures thereof. Water conditioning can be achieved by different mechanisms including sequestration, ion exchange and dispersion (threshold effect). The water conditioning agents that can be employed in the detergent compositions of the invention may be of inorganic or organic nature; and, soluble or insoluble in water when used in dilution concentrations. These act to remove Ca2 + and Mg2 + from the dirt / surface interface by an action of chelation to sequestration.

(a) A patent by its nature is very affected by the public interest. The public interest is best served, and the most effective patent examination occurs when, at the time a request is to be examined, the Office knows and evaluates the teachings of essential information to be patented. Each person associated with the filing and processing of a patent application has a duty of sincerity and good faith in dealing with the Office, which includes the duty to disclose to the Office all information known to that person that is essential to be patented according to what is defined in this section. The duty to disclose the information exists with respect to each pending claim until the claim is canceled or withdrawn from consideration, or the request is abandoned. The essential information to be patented of a claim that is canceled or withdrawn from consideration does not need to be presented if the information is not essential to be patented in any claim that remains under consideration in the application. There is no duty to present information that is not essential to be patented of any existing claim. The duty to disclose all information known to be essential to be patented is considered satisfied if all information known to be essential to be patented of any claim issued in a patent was cited by the Office or presented to the Office in the manner stipulated by Sections 1.97 (b) - (d) and 1.98. However, a patent will not be granted on an application related to which office has been practiced or attempted or the duty of disclosure is violated through intentional or bad faith misconduct. The Office encourages applicants to carefully examine: (1) the prior art cited in the search reports of a foreign patent office in a counterpart request, and (2) the intimate information on which the people associated with the presentation or processing of a patent application believe that any pending claim defines patentability, any essential information contained therein disclosed to the Office is safe. (b) Under this section, the information that is essential to be patented when the information is not cumulative is ready to be registered or registered in the application, and (1) Establishes, by itself or in combination with other information, a first time case of non-patentability of a claim; (2) Refutes, or is inconsistent with, a position the applicant takes in: (i) Opposition to an argument of non-patentability considered by the Office, or (ii) Enforce an argument of patentability. A first-time case of non-patentability is established with information that compels a conclusion that a claim is not patentable according to the preponderance of the evidence, normal test charge, giving each term in the claim a reasonable construction more broad consistent with the specification, and before any consideration given as evidence with which it may be presented in an attempt to establish a contrary conclusion of patentability. (c) The persons associated with the filing or processing of a patent application within the meaning of this section are: (1) Each inventor named in the application: (2) Each attorney or agent who prepares or processes the application; and (3) Any other person who is substantially involved in the preparation or processing of the application and who is associated with the inventor, with the transferee or with any with whom there is an obligation to assign the request. (d) Persons other than the lawyer, agent or inventor may comply with this section by disclosing the information to the attorney, agent or inventor.
