Description

COMPOSITIONS FOR CLEANING AND DISINFECTION TECHNICAL FIELD OF THE INVENTION The present invention relates to a composition that provides cleaning, disinfecting and gloss performance on surfaces, especially on hard surfaces.

BACKGROUND OF THE INVENTION The compositions for efficient cleaning and disinfection are usually formulated on the basis of surfactants that provide the cleaning and disinfecting properties required of the surfaces that are treated therewith. Particularly suitable surfactants having such properties are, for example, amine oxide surfactants. However, in formulating the compositions with said surfactants it has been observed that they can leave residues on the hard surfaces treated therewith, resulting in surfaces that do not look glossy. In fact, the problem of providing lustrous surfaces often has to do with the residues of the compositions remaining on said surfaces and which look like veins after the water has evaporated. The waste problem can be observed when the compositions are used to treat surfaces made of shiny materials, such as shiny ceramic mosaics, windows and mirrors, or materials such as PVC coated with polyurethane that has wide use in North America. In addition, currently, many products are formulated or can be used as products that do not require rinsing. In such conditions or with such products, the problem of waste has become more acute. Thus, there is a need for a composition that provides effective cleaning and disinfecting performance, but also provides the treated surfaces with a lustrous effect without any residue. Various solutions have been proposed in the art to meet this need, including the use of an acid, magnesium ions or the use of some solvents as described in WO 95/21229, EP 0 639 833 or US 3,839,234. Surprisingly, the applicant has discovered that this need can also be met by formulating a composition comprising a surfactant system consisting of an amine oxide (0.01% to 10%), a long chain alkyl sulfate (0.01% -20%) and a short chain alkyl sulfate (0.01% to 20%). In fact, it has been discovered that the addition of such long chain alkyl sulfate in a composition comprising an amine oxide and a short chain alkyl sulfate improves the gloss properties that said composition provides when used to treat a hard surface, this when Use in undiluted or diluted conditions. This finding is especially surprising since it has been discovered that by using amine oxide surfactants alone and alkylsulfate surfactants alone, both providing effective cleaning and contributing to effective disinfection, they form crystals upon drying, which results in Result of stain residues on the treated surfaces. Surprisingly the use of a mixture of an amine oxide as defined herein, a long chain alkyl sulfate and a short chain alkyl sulfate as defined herein, in a composition, especially a liquid composition, not only provides a cleaning Effective disinfection and effective disinfection of hard surfaces treated with this composition also causes said residues to be less evident or even not to reappear. It is therefore an advantage of the invention to provide a composition that provides effective cleaning, disinfecting and gloss performance on surfaces. The Applicant has additionally discovered that the addition of solvents to this surfactant system provides additionally improved cleaning and gloss benefits. In a preferred embodiment, the compositions herein further comprise a peroxygen-based bleach and / or an antimicrobial compound similar to the antimicrobial essential oils or active thereof. These ingredients provide improved disinfection performance on hard surfaces, even at high dilution levels, for example, at 1: 100 dilution levels (composition: water).

Therefore, another advantage of the invention is that it provides a composition with improved disinfection performance. A further advantage of the invention is that it provides a composition that is soft on the skin.

By "cloth", it is meant in the present invention disposable towels, for example, paper towels, which incorporate a composition in accordance with the present invention. In this way, the present invention also includes cloths, for example, disposable paper towels, which incorporate a liquid composition in accordance with the present invention. In the preferred embodiment said wipes are impregnated, most preferably wetted with said liquid compositions. Preferably said cloths are packed in a plastic box. The advantage of this presentation is the faster use by the user of a composition for cleaning / disinfection, this even outside the home, that is, there is no need to pour liquid compositions according to the present invention on surfaces to be treated and dry them with a cloth. In other words, the cloths allow the cleaning and disinfection of surfaces in a single step. The present invention includes a method for treating surfaces wherein a composition in accordance with the present invention is applied to said surfaces. "Surface" includes any hard surface that is typically found in homes such as kitchens, bathrooms, or car interiors, for example, mosaics, walls, floors, chrome, glass, smooth vinyl surfaces, any plastic, laminated wood, decks of tables, laundry rooms, kitchen work tables, dishes, sanitary articles such as tarjas, showers, curtains for bathrooms, washrooms, toilets and the like, as well as any domestic article that includes, but is not limited to refrigerators, freezers, washing machines, dryers automatic, furnaces, microwave ovens, dishwashers, etc. In the process for treating the surfaces according to the present invention said compositions can be applied to the surface to be treated in pure form or in diluted form. By "treatment" is meant in the present invention cleaning and disinfection, since the compositions of the present invention comprise surfactants having both properties. By "dilute form" it is meant in the present invention that the compositions that are used in the present process will be in liquid or solid form and the user can typically dilute them up to 500 times their weight in water, preferably up to 300 times, most preferably up to 200 times, even most preferably 80 to 30 times its weight in water, and very much preferably 60 to 40 times. In a preferred embodiment of the process of the present invention said compositions are applied to a surface to be treated, such as a hard surface, in its diluted form, it is not necessary to rinse the surface after applying the composition; in fact, no visible residue remains on the surface. The following test methods applied to measure the cleaning and gloss benefit were made as indicated below: Cleaning test method Standard varnished plates were stained by applying a grease / particle material on them and subsequently baked. Subsequently, in a sponge the compositions to which the test was carried out were applied and then placed in a Gardner machine. The Gardner machine measured the number of carvings needed to achieve a cleanliness of 95 to 99% of the plates. The yield was measured as such (ie undiluted) and with a 1.5% dilution in water.

Brightness test method Five millimeters of the product that was tested on one side of a wet sponge was applied. The wet sponge is applied in a single movement with a uniform pressure from the top to the bottom of a black mosaic previously cleaned with isopropyl alcohol. The mosaic with the applied products is allowed to dry for 10 minutes before the evaluation of the expert judges. The control reference is made by repeating the above method with a wet sponge but without the test product. The expert judges evaluate the specific area of application of the product to obtain the amount of film / veining formation. A numerical value that describes the amount of film / grain formation is assigned to each product. A scale of 0 to 4 was used for the test results. 0 = There is no difference between the test product and the control reference, ie a low film / grain formation performance of the tested product. 4 = There is a clear difference between the product and the control reference, ie without film / veining formation with the test product.

The invention is illustrated with the following non-limiting examples, wherein all percentages are shown on a weight basis, unless otherwise specified. In the examples, the identifications of abbreviated components have the following meanings: Amine oxide: N-decyldimethyl amine oxide C8AS: C8 C1 alkyl ester OAS: C7 C7-8AS alkylsulfate: Synperonic 91: 5 C7-C8 alkyl sulfate: Cg-Cn ethoxylated penta alcohol HEDP: 1-hydroxyethylidene-bisphosphonic acid Butyl carbitol®: 2- (2-butoxyethoxy) ethane EXAMPLES The following compositions were made in accordance with the present invention by mixing the ingredients listed in the proportions indicated (% by weight): 3 The above compositions provide effective cleaning and disinfecting performance to the surface treated therewith, under both pure and diluted conditions while providing the treated surface with a lustrous effect.
