Abstract

A detergent composition for cleaning hard surfaces comprises: a diphenyl ether disulfonate anionic surfactant, a water-soluble organic solvent, an amino compound, and water. The composition is especially easy to wipe off the cleaned surface.

Description

TITLE OF THE INVENTION: DETERGENT COMPOSITION FOR HARD SURFACES BACKGROUND OF THE INVENTION i) Field of the Invention: This invention relates to a detergent composition for hard surfaces, and more specifically to a detergent composition for hard surfaces, which is excellent in easiness of wiping, scarcely remains on the surface cleaned after its wiping to give a good result, and possesses excellent detergency to dirt or smears, in particular, deteriorated oil and grease smears.

ii) Description of the Background Art: As detergent compositions for hard surfaces, the following compositions have hitherto been used properly according to the kind and degree of dirt.

Namely, surfactant-solvent type detergents and surfactant-solvent-alkaline agent type detergents have been principally used respectively for dirt from the hands and undeteriorated oil and grease smears, which are relatively light in degree of dirt, and for oil and fat smears appeared in or near a kitchen and deteriorated by an action of heat, sunlight, oxygen in air and/or the like, and the like.

However, when these detergents are used, the surfactant and alkaline agent remain on the surfaces cleaned after wiping off the detergents, so that wipe streaks are left even after the cleaning, leading to an insufficient result.

Therefore, these detergents require double wiping or sufficient rinsing with water, and are hence complicated.

As an attempt to solve such a problem, Japanese Patent Application Laid-Open No. 29498/1990 discloses a liquid housecleaning detergent composition which comprises, as essential components, an anionic surfactant, a terpene hydrocarbon solvent and a water-soluble salt of a divalent metal, is excellent in cleansability and safe for the human body, scarcely affects substrates, and requires no rinsing.

This detergent composition has shown a considerable improvement from the viewpoint of finish upon cleaning a glass surface or the like, but has required a further improvement from the viewpoint of practical use. Japanese Patent Application Laid-Open No. 501570/1987 (through PCT route) discloses a detergent composition composed of a glycoside surfactant, a solvent, a water-soluble detergent and a builder. However, this composition has also required sufficient rinsing because a portion of the composition has been observed remaining after wiping it.

Further, Japanese Patent Application Laid-Open No.

85400/1992 has proposed a liquid detergent composition which comprises a specific anionic surfactant and a specific amphoteric surfactant, has high detergency and leaves little wipe streaks. This composition has however overfoamed upon its wiping due to its high foaming power, and has hence been poor in easiness of wiping (easiness of wiping operation).

On the other hand, alkyl diphenyl ether type surfactants having two sulfonic groups in their molecules have heretofore been used widely, for example, as emulsifiers upon preparation of polymers, chemical agents for fiber-dyeing processes, dispersing agents for agricultural chemicals and dispersants for crude oil sludge.

However, it has not been known to use them in surfactantsolvent-amine compound type detergents for hard surfaces.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a detergent composition for hard surfaces, which is excellent in easiness of wiping, to say nothing of detergency, and leaves little wipe streaks to give a good result, In view of the foregoing circumstances, the present inventors have carried out an extensive investigation. As a result, it has been found that when a diphenyl ether disulfonate type anionic surfactant, a water-soluble solvent and an amine compound are blended, a detergent composition which has excellent detergency to dirt, in particular, deteriorated oil and fat smears, is good in easiness of wiping, and scarcely leaves wipe streaks to give a good result, leading to completion of the present invention.

In an aspect of the present invention, there is thus provided a detergent composition for hard surfaces, which comprises the following components (A), (B) and (C): (A) a diphenyl ether disulfonate type anionic surfactant, (B) a water-soluble solvent, and (C) an amine compound.

In another aspect of this invention, there is also provided a detergent composition for hard surfaces, which comprises the following components (A), (B) and (C): (A) 0.01-20 wt.% of a diphenyl ether disulfonate type anionic surfactant, (B) 0.1-50 wt.% of a water-soluble solvent, and (C) 0.01-30 wt.% of an amine compound.

The detergent compositions for hard surfaces according to the present invention have high detergency, in particular, to deteriorated oil and grease smears, are excellent in easiness of wiping, scarcely remains on the surfaces cleaned after their wiping and also show good finishing behavior.

The above and other objects, features and advantages of the present invention will be readily appreciated from the preferred embodiments of the present invention, which will be described subsequently in detail.

The detergent composition for hard surfaces according to a preferred embodiment of the present invention is -obtained by blending the above-described components (A), (B) and (C), and satisfies all of detergency, in particular, to deteriorated oil and grease smears, easiness of wiping, and finishing behavior. However, all such effects can not be exhibited if any one of these components is omitted.

In the detergent composition for hard surfaces according to another preferred embodiment of the present invention, the effects of the present invention can be more enhanced by blending the components (A), (B) and (C) in specific proportions. The component (A) may preferably be blended in a proportion of 0.01-20 wt.% (hereinafter indicated merely by "%"), more preferably 0.01-10%, most preferably 0.1-3% of the whole amount of the detergent composition. The component (B) may be preferably be blended in a proportion of 0.1-50%, more preferably 1-3u%, most preferably 1-20% of the whole amount of the detergent composition. The component (C) may be preferably be blended in a proportion of 0.01-30%, more preferably 0.01-20%, most preferably 0.05-10% of the whole amount of the detergent composition.Any amounts of the component (A) less than 0.01% result in a detergent composition insufficient in detergency. On the other hand, if the component (A) is blended in any proportion exceeding 20%, the effects of enhancing the easiness of wiping and finishing behavior according to the present invention are not expected to more heighten correspondingly. Any amounts of the component (B) less than 0.1t result in a detergent composition not wholly satisfied in detergency, while any proportions exceeding 50% result in a detergent composition impaired in finishing behavior. It is not hence preferable to blend the component (B) in any proportions outside the above range. If the amount of the component (C) is less than 0.01%, its influence on the detergent effect becomes insufficient, and its blending will hence mean little.On the other hand, if the component (C) is blended in any proportion exceeding 30%, the effects of the present invention can not be more heightened correspondingly.

The detergent compositions for hard surfaces according to the present invention may optionally contain, as a component (D), at least one surfactant other than those described above within limits not impeding the effects of the present invention. No particular limitation is imposed on such a surfactant. However, it may preferably comprise one or more surfactants selected from the group consisting of nonionic, anionic and amphoteric surfactants. Specific surfactants useful as the component (D) are as follows.

As examples of the anionic surfactants, may be mentioned alkylbenzene sulfonates, alkylene oxide-added alkyl (or alkenyl) ether sulfates, alkyl- or alkenylsulfates, olefinsulfonates, alkanesulfonates, fatty acid salts, alkylene oxide-added alkyl (or alkenyl) ether carboxylates, a-sulfo-fatty acid salts and esters thereof, and the like.

As examples of counter ions to the anionic surfactants, may be mentioned alkali metal ions such as sodium and potassium ions, ammonium ion, and alkanol substituted ammonium ions such as monoethanolammonium, diethanolammonium and triethanolammonium.

As examples of the nonionic surfactants, may be mentioned polyoxyalkylene alkyl (or alkenyl) ethers, polyoxyalkylene alkylphenyl ethers, sucrose fatty acid esters, fatty acid glyceryl esters, amine oxides, higher fatty acid alkanolamides or their addition products with alkylene oxides, and alkylglycosides represented by the following general formula (10): R21(OR22)xGy (10) wherein R21 means a linear or branched alkyl, alkenyl or alkylphenyl group having 8-18 carbon atoms, R22 denotes an alkylene group having 2-4 carbon atoms, G represents a residue derived from a reducing sugar having 5-6 carbon atoms, x stands for a number of 0-5 in terms of the average value, and y means a number of 1-10 in terms of the average value.

In the general formula (10), x is a number of 0-5 in terms of the average value. Both water-solubility and crystallinity of the detergent compositions according to the present invention are controlled by this value. Namely, the compositions have an inclination that the water-solubility becomes higher and the crystallinity becomes lower as x increases. The value of x is preferably 0-2, with 0 being particularly preferred. On the other hand, when y is greater than 1 in terms of the average value, namely, a surfactant represented by the general formula (10) and containing a di- or higher polysaccharide chain as a hydrophilic group is contained, the bond form of the saccharide chain may be a 1-2, 1-3, 1-4 or 1-6 bond, or an alpha- or beta-pyranoside or furanoside bond. It is also possible to contain any mixture having a combined form of these bonds.The average value of y in the general formula (10) may be 1-10, preferably 1-3, more preferably 1-1.5, most preferably 1-1.4. Incidentally, the measurement of y in this invention is based on the proton NMR method.

Further, R21 in the general formula (10) may be a linear or branched alkyl, alkenyl or alkylphenyl group having 8-18 carbon atoms. However, alkyl groups having 1014 carbon atoms are preferred from the viewpoint of improvement in solubility, foamability and cleansability.

Furthermore, R22 may be an alkylene group having 2-4 carbon atoms. However, the number of carbon atoms is preferably 23 from the viewpoint of the solubility in water. Moreover, the structure of G is dependent upon the raw material to be used, which is a monosaccharide or di- or higher polysaccharide. As examples of the raw material for G, may be mentioned monosaccharides such as glucose, fructose, galactose, xylose, mannose, lyxose, arabinose and mixtures thereof; and disaccharides and higher polysaccharides such as maltose, xylobiose, isomaltose, cellobiose, gentiobiose, lactose, sucrose, nigerose, turanose, raffinose, gentianose, melezitose and mixtures thereof. Of these, preferred materials are glucose and fructose for the monosaccharide, and maltose and sucrose for the di- or higher polysaccharide because of their good availability and low cost.Of these, glucose is particularly preferred from the viewpoint of availability.

In addition, examples of the nonionic surfactants include nonionic surfactants containing at least one longchain, branched alkyl or alkenyl group and at least three hydroxyl groups in their molecules, such as an addition compound of pentaerythritol with 1 mole of isostearyl glycidyl ether, an addition compound of sorbitol with 1 mole of isostearyl glycidyl ether, an addition compound of mannitol with 1 mole of 2-octyldodecyl glycidyl ether, an addition compound of methylglucoside with 1 mole of isostearyl glycidyl ether, an addition compound of diglycerol with 1 mole of isostearyl glycidyl ether, and phytanetriol.

As examples of the amphoteric surfactants, may be mentioned sulfobetaines and carbobetaines containing a linear or branched alkyl or alkenyl group having 1-22 carbon atoms, and the like.

In the present invention, among the above-mentioned surfactants, the higher fatty acid alkanolamides or their addition products with alkylene oxides, amine oxides, alkylglycosides, sulfobetaines and carbobetaines are preferred from the viewpoint of improvements in detergency and easiness of wiping, with the alkylglycosides being particularly preferred.

If these surfactants of the component (D) are blended, the proportion thereof is 0.01-20%, preferably 0.05-10%, most preferably 0.05-5%. If the amount of the surfactants is less than 0.01%, the surface activity brought by the component (D) is not sufficiently exhibited, and its blending will hence mean little. On the other hand, if the component (D) is blended in any proportion exceeding 20%, its effects are not expected to more heighten correspondingly. There is hence no need to blend the component (D) in an amount exceeding 20%.

In order to more improve the storage stability at low temperatures, the detergent compositions of this invention may optionally contain, in addition to the above-described components, the routinely-used dispersants, chelating agents, perfume bases, dyes, pigments, antiseptics and the like within limits not impeding the effects of the present invention.

The detergent compositions for hard surfaces can be prepared by mixing the aboveodescribed components and water in a method known Per se in the art.

The present invention will hereinafter be described in more detail by the following examples. However, it should be borne in mind that this invention is not limited to and by these examples.
