In fact, the present invention relates to the cleaning of different surfaces, such as hard surfaces, carpets or any cleaning application, including the pre-treatment of m nch.

LQS BACKGROUND e has described extensively in the art a < -) \ variety of compositions 1 implant. Typically, the cleaning compositions can be divided into cleaning compositions for hard surfaces and liming compositions for washing clothes. The cleaning compositions of two additional types have a very different formulation and are sold under different products, with marketing concepts. These differences require the consumer to have < | to buy and use at least two different products. In addition, the compositions (ie the two original types, especially the hard surface cleaners, can be divided into * subtypes.) In reality, many kinds of cleaners are available for hard surfaces, for example, cleaner for cleaning. or, cleaners for par-a? oc or cleaners for iso. b This variety in the formulation is necessary because of the difference in the nature of the dirt which is found in the washing of clothes and in various Super fi cials of kitchens, floors, and kitchens, For example, kitchen soils comprise principally edible oils, while bathroom soils comprise mainly sebum and soap foam, and also hot adhesions. The soils of the floor mainly comprise particulate soils and the laundry may have many different soils and stains, however, there is a tendency to develop 5 cleaning compositions with better performance in various ways. spectos, that is to say, * multipurpose liquid cleaners, which can be used satiaily on different surfaces, as well as in laundry applications, to clean various soils and stains. Such multi-purpose compositions are described, for example, in European patent application EP-rV? Lfl, 173. In fact, that patent application describes compositions comprising hydrogen peroxide with a totally non-unique system, that is, at least one non-ionic equilibrium with an equilibrium b hydrofi lo / l ipofi Lo (EHl) greater than 15, at least one non-ionic one with an EHL of 13 1 5, at least one non-ionic a f-IHI of qa 13, and at least one non-ion with a superior TUL '-) "This pat application describes additionally the use of two to which Lcanoles as suds suppressors in said compositions. However, it has been discovered that said compositions comprising hydrogen peroxide, a 2-cyclohexane and a surfactant system have a specific non-specific system of at least four non-ionic agents that have Different EHI (hydroflobal equilibrium), as defined here before, does not satisfactorily meet the needs of the consumer. In fact, said compositions based on a totally non-ionic surfactant system and comprising a high level of hydrophobic surfactants, were found to have malfunction in some kinds of stains in the laundry application. Although said hydrophobic nonionic surfactants have good grease-cutting properties and are particularly effective on greasy soils having a hydrophobic nature, such as mineral oil and soap foam, when used in a hard surface cleaning composition. It has been found that when non-ionic surfactants hydrophobes are used in tope washing applications, blanquoable spots are not whitening satisfactorily. The wetting capacity of the stains is affected by the non-ionic system of the said compositions, that is, the good contact between the hydrogen peroxide and the stains on the fabrics is prevented. which results in the operation on ona stain h lanq eable. It has also been found that there is a problem associated with <; ---! use of said ingredients, that is to say, the nonionic surfactants hydrophobes and the 2-al qui lalcanol is, because they can cause the final product to appear cloudy, which indicates insolubility and phase separation. Thus, it is an object of the present invention to formulate a multi-purpose liquid cleaner that can be used successfully on various surfaces as well as in laundry applications, to clean various soils and stains. It is a further object of the present invention to provide such a composition, which is a clear composition on a wide range of temperatures, for example, up to 50 ° W. The compositions according to the present invention must be capable of working under a variety of conditions, i.e. in hard and soft water, as well as when used as such or diluted. They should provide a performance of brightness and factori and safety of surfaces when used as hard surface cleaners. In other words, is it an object of the present invention to provide an aqueous multi-purpose composition, which provides improved performance for washing clothes on bleach spots and other hydrophilic spots, while also supplying? \ na L Cleaning of outstanding grease for a variety of surfaces, as well as for the laundry application. It has now been discovered that these objectives can be efficiently fulfilled by formulating * a cleaning composition comprising hydrogen peroxide,? -alkylalkanol and a specific surfactant system comprising at least one hydrophobic surfactant having an EHl ( equilibrium hi drofi lo / li poflio) less than 14, preferably a nonionic surfactant and at least one ammonium surfactant, preferably an alkyl sulfate. In fact, it has been found that by combining these four ingredients a multi-purpose cleaning composition is provided which exhibits the flexibility in the stains it can clean. It has been found that said composition gives a strong cleaning performance, specifically in laundry applications, that is, said composition gives good performance on blotchy hydrophilic stains, as well as greasy stains that are limited. It has also been discovered that the? -alqu? laleanoles reinforce the effect of a given hydrophobic surfactant system, in terms of fat cleansing performance. More particularly, for any given cleaning composition comprising a hydrophobic surfactant and providing a given cleaning performance, a surface treated with it will be added, adding 2-1% of thecanol to improve said fat cleaning performance. Finally, it has surprisingly been found that the use of α-α-alkylcanol together with a hydrophobic nonionic surfactant having a 171-11 of less than 14, results in a synergistic effect on the cleanliness of the grease. It is an advantage of the compositions herein that the foam forming profile herein is particularly suitable for application to hard surfaces, where having a correct level of foam is critical. In fact, an advantage of the present invention is that rinsing of the surface is facilitated. Another advantage of the present invention is that a multi-purpose cleaning composition is provided, very cost effective, with excellent performance in hard surface cleaning applications, carpet cleaning applications and laundry applications. Cleaning compositions comprising 2 -alkyl alkanols have been described in the art: DE 40 21 265 discloses that branched alcohols in the 2-position are effective foam presurers. That patent application describes compositions comprising an -alkylcanol together with ethoxylated nonionic alcohols having fatty alcohol chain lengths ranging from 13 to 17 carbon atoms, and an etching degree of 3 to 7. Compositions comprising bleaching are not disclosed. Furthermore, that patent application does not at any point describe the benefits in fat cleaning performance associated with the use of 2-alkyl lalcanol in conjunction with a hi-wolf stereoactive agent, EP-A-5Q3, 841 describes compositions that they comprise a surfactant and, with or a suds suppressor system, the combination of branched alcohols, for example, 2-alkylalanols and silicone oils. Different types of surfactants are disclosed which include the broadly defined ammonium, nonionic, cationic and zwitter ionic surfactants. That patent application in no way discloses that said compositions may further comprise bleach, even hydrogen peroxide alone.

That solitude mentions that said short chain agents provide stability to the compositions comprising them and that they mean simply raise the overall cleaning bond, especially the grease cleaning. However, that patent application does not mention that 2- al qui Lalcanol.es increase the capacity of the hydrophobic surfactants to clean the grease.

N lower EHL * to 14, will improve the fat cleansing of the composition. By "improving the cleaning of fat" it is to be understood herein that the cleaning of fat obtained by using the -a-L-lalcanol together with a hydrophobic surfactant having an inner EHl at 14, in a given composition, is improvement compared to the cleaning of fat obtained with the same composition comprising either only one or both of said two additional compounds, or it has also been found that the synergistic effect on the fat-forming performance is associated with the use of a 2- J qui lacanol with non-ionic, hydrophobic surfactants, in aqueous cleansing compositions The fat cleansing function of a composition can be evaluated by means of different fat testing methods, such as GSS (fatty soapy foam dirt), a method used later in the examples.An advantage associated with the present invention is that, due to the use of a 2-al qui la canol, a good n foam profile. In fact, the present invention allows to avoid too much foaming, which is probably harmful to the gloss and makes it difficult to rinse for the consumed. In other words, it is possible to have the desired foam profile with the present invention without the need to add any additional foam suppressant ingredients, such as the foam suppressors that are based on whether Lir n, which are detrimental to the peroxide stability of hydrogene? and the aesthetics of the composition. The present invention will be better illustrated with the following examples.
