Description

CqnpqsXCIQNES UMF ?? PPR S PE gy and CRFtciES PUPAS C? ÜPQ TECHNICAL The invention relates to the cleaning of hard surfaces »in particular» but not exclusively floors.

BACKGROUND OF THE INVENTION Compositions for cleaning hard surfaces have been extensively described in the art. It is desirable that said compositions should have-in addition to the ability to effectively cleanse-the ability to provide adequate gloss to the surfaces that have been cleaned therewith. However, the surface gloss is often compromised by the residues of the compositions that remain on the surfaces and appear as lines as the evaporation of the water ends. This problem becomes more acute when the compositions are used without rinsing after cleaning "and when the compositions are formulated as concentrated compositions" which comprise more active agents and less water. It is thus "an object of the present invention to provide compositions for cleaning hard surfaces" that efficiently clean in concentrated or diluted form "and that they leave few streaks or none at all after cleaning.

BRIEF DESCRIPTION OF THE INVENTION In a first embodiment, the invention encompasses the use of a hard surface cleaning composition. (a) a hydrophilic nonionic surfactant "and (b> a C?-Cl? í alcohol in a weight ratio of < a)! (b) from lü to 10! 1 »for improved brightness of hard surfaces that have been cleaned with it. In a second embodiment »the invention covers the use» of a hard surface cleaning composition »of? (c> a hydrophobic nonionic surfactant "and (d) a sulfated anionic surfactant! and (b) a CS-Clß alcohol" in weight ratios of (c)? (b) of 5% by weight. 1"and from (d)! (C) from 1 to 0" for improved brightness of hard surfaces that have been cleaned therewith.In a third embodiment "the invention combines the first two modalities and thus encompasses" the use " in a hard surface cleaning composition of (a) a hydrophilic nonionic surfactant and (b> a C8-C1T alcohol; and (c) a non-ionic hydrophobic surfactant; and (d) an agent sulfated anionic surfactant » in weight ratios of < to)! < b > from l? l to 10! 1 of < c)! < b) from 5 ° to 25 ° "and from (d) :( c) from 1 to 10 °" for improved brightness of hard surfaces that have been cleaned therewith. In a fourth embodiment "the invention encompasses a hard surface cleaning composition" comprising! (c> a hydrophobic nonionic surfactant! and (d) a sulfated anionic surfactant! and (b) a C? -Cl? alcohol in weight ratios of (c)! (b) of 5; 1 to 25"1" and from (d) :( c) from 1 to 100. Preferred in said fourth embodiment "is a composition further comprising a nonionic hydrophilic surfactant (a)" and wherein additionally the weight ratios (a)! (b) is from 10 to 10! 1. The invention further encompasses methods for cleaning hard surfaces with the compositions "either in pure or diluted form.

PESCPIPCIQN ET? TAA P tA INVENTION In some embodiments of the invention, various components are combined and used in a hard surface cleaning composition for the purpose of providing gloss to said surfaces which are cleaned with the compositions. As used in the present »" hard surface "are typically referred to to floors »walls» windows »kitchen and bathroom furniture» appliances and vaj i 1 las.

Obtaining a good final result of brightness is essentially the sum of two factors »namely! good dispersion of the cleaning product on the surface "and absence of crystallization while drying occurs. If both factors are achieved, a final score-free result is obtained. The phenomenon of streak formation can be described as well as the appearance of visible residues from the cleaning composition »according to the water in the composition or the rinse water evaporate. Molecular crystallinity and aggregation during evaporation cause the formation of streaks, thus giving a poor final gloss result. Thus "as used herein" the ability of a composition to provide "gloss" to surfaces refers to the ability of the composition to leave little or no residue visible to the human eye on surfaces "after evaporation of water . In most cases, "the ability of various compositions to provide brightness can be evaluated with the naked eye" but it is also possible to evaluate the difference by means of a "brightness meter" such as a Sheen R 155 brightness meter. suitable to evaluate the ability of a composition to leave little or no res; i duo »is to first measure the brightness of a surface given »then apply the cleaning composition on the surface» then let the composition dry »and finally measure again the brightness of the surface on which the composition has been applied. The smaller the difference, the better the brightness.

Of all polycarboxylate builders »the most preferred to be used in the present is citrate. The compositions herein comprise from 0.5% to 5% by weight of the total composition of the builder system, preferably from 0.5 to 37. Another characteristic of the compositions herein is that components (a) to (d) ) must be present in certain specified relationships.

The second block of technology is the combination of the selected hydrophobic ionic surfactant with the alcohol selected in the selected ratios along with the selected sulfate anionic surfactants. Similar to the first block of technology, "these nonionic surfactants and anionic surfactants are particularly effective on particulate soils and greasy soils" but will cause streaking if used independently. The addition of alcohol "in selected ratios" results in a clear benefit of brightness. The third block of technology is the mixed detergency builder system. Palicarboxylates with surfactants would cause streaking "and carbonate or polyphosphates with surfactants would cause a crystalline film to deposit on the surface. However, the combination of these detergency builders, together with surfactants, does not leave visible streaks or any film. This improvement in performance is particularly visible in the presence of anionic surfactants, since these surface active agents tend to form lines when they are already in pure form.

The compositions herein may further comprise several other optional ingredients. Such optional ingredients include bleach »enzymes» colorantee »perfumes and other ingredient eetét oe. The compositions herein are preferably formulated as aqueous liquids. They may comprise from 1% to 30% by weight of the total composition »of active agents, ie» from 99% to 70% of water. As used herein, "pure" refers to a composition comprising that amount of active agents. In a first embodiment the composition of the present is applied in pure form on a surface in order to clean it and is optionally removed but preferably subsequently by rinsing with water. In a second embodiment »the compositions are first diluted in water» typically 40 to 320 times »and then applied to the surface to be cleaned. Then »in this second mode» the composition can »but not necessarily» have to be rinsed from the surface. The first mode is generally more suitable for heavily soiled surfaces, while the second mode is generally more suitable for large and slightly soiled surfaces such as floors.
