Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a milky liquid hard surface cleaner composition for cleaning hard surfaces such as tableware, cookware, sinks, bathrooms, toilets, floors, walls and metal surfaces. The present invention relates to a milky liquid hard surface cleaner composition which not only has excellent cleaning properties and foaming properties on these hard surfaces, but also has an excellent feeling in use and has less rough hands.

2. Description of the Related Art Generally, a hard surface cleaning agent used for cleaning hard surfaces such as tableware usually has a main purpose of removing greasy stains, and a user is a cleaning agent. In most cases, oil and grease stains are removed by whipping with a hand or sponge during use. The function of the foam at this time is to relieve the force required to scrape off the dirt, and in many cases, the amount of foaming is often a measure of the cleaning property of the oil and dirt. Therefore, in such a detergent, its high foaming power is an important factor, and conventional hard surface detergents have alkylbenzene sulfonate, α-olefin sulfonate, alkyl sulfate, alkane sulfonate, as main surfactants. Anionic surfactants such as ethoxylated alkyl ether sulphates have been used. Among them, sodium alkylbenzene sulfonate has been widely used as a base having excellent cleaning performance, but it has a drawback that it has a strong degreasing power from the skin and is likely to cause rough hands.

In order to prevent this drawback, conventionally, an anionic surfactant has been used as a main cleaning base, and a nitrogen-containing, amphoteric or nonionic, such as a tertiary amine oxide, higher fatty acid alkanolamide or alkyl betaine, has been used. What was used together with the characteristic surfactant was used.

However, such a detergent composition has not yet reached a satisfactory level, although the action of the anionic surfactant as the main base on the skin has been moderated to some extent.

On the other hand, alkyl glycosides, which are sugar derivative surfactants, are not only mild surfactants but also nonionic surfactants, but not only generate stable foams themselves, It is known to act as a foam stabilizer against other anionic surfactants, and has been attracting attention in recent years. For example, JP-A-58-104625
JP-A-62-7 discloses a foaming surfactant composition containing an alkyl glycoside and an anionic surfactant.
Japanese Patent No. 4999 describes a liquid dishwashing liquid detergent composition containing an alkylglycoside, an anionic surfactant and a fatty acid alkanolamide, which has low irritation and excellent foaming power and detergency. In addition, JP-A-1-304198
The publication describes a hard surface cleansing composition containing an alkyl glycoside and a fatty acid ester of a polyhydric alcohol and having high skin mildness.

However, these detergent compositions are superior in the action on the skin as compared with the detergent compositions containing the above-mentioned anionic surfactant as the main detergent base, but they are still insufficient. However, the sebum component of the hand skin was removed, and there was a problem in that the feel of the hand skin after use was worsened, which was a problem. Therefore, there has been a demand for a hard surface cleaning composition which is excellent in detergency and foaming power, does not cause rough hands, and has a good feel on the skin after washing.

[0007]

Under these circumstances, the present inventors have conducted earnest research to improve the above problems, and as a result, in a detergent composition containing an alkyl glycoside and an anionic surfactant. In addition, it was found that, if a certain amount of a specific glycerin fatty acid ester is blended, it is possible to obtain a hard surface cleaning agent which is excellent in detergency and foaming power, does not cause rough hands, and has a good feeling after washing, and thus completed the present invention. did.

That is, the present invention provides the following components (a)-

X is a number whose average value is 0 to 5, and this value controls the water solubility and crystallinity of the alkyl glycoside. That is, the higher x, the higher the water solubility and the lower the crystallinity. Preferably the value of x is 0-2. Further, y is a number whose average value is 1.0 to 1.42. Further, when the average of y is greater than 1, that is, when it contains a surfactant represented by the general formula (1) having a sugar chain of two or more sugars as a hydrophilic group, the binding mode of the sugar chain is 1
It is possible to include -2, 1-3, 1-4, 1-6 bonds, as well as [alpha]-, [beta] -pyranoside or furanoside bonds and any mixtures thereof with mixed bond modes.
The measuring method of y in the present invention is based on the proton NMR method.

The component (a), an alkyl glycoside, can be used alone or in combination of two or more kinds, and is incorporated in the composition of the present invention in an amount of 1 to 40% by weight, preferably 5 to 20% by weight. If the blending amount is less than 1% by weight, the basic performance such as excellent foaming power and detergency cannot be satisfied, and the blending amount is 40% by weight.
Above the above range, the composition remarkably thickens, which causes another problem that it is difficult to take out the composition-filled container. The anionic surfactant as the component (b) used in the present invention is
Any one may be used as long as it has good compatibility with the component (a), economy, etc., and is not particularly limited. Suitable examples of the component (b) are shown below.

(5) Alkane sulfonate having 10 to 18 carbon atoms. Examples of the salt include alkali metal salts, alkaline earth metal salts, ammonium salts, alkanolamine salts and the like. These anionic surfactants can be used alone or in admixture of two or more. The component (b) is incorporated in the detergent composition of the present invention in an amount of 1 to 40% by weight, preferably 5 to 20% by weight.

Since the glycerin fatty acid ester as the component (c) is also one of the sebum components, it can be incorporated into the composition of the present invention in a specific ratio so that it remains on the skin after use and is moisturized. It has the function of giving a feeling and protecting the skin of the hands. Therefore, in order for this component to remain on the skin, it can be said that a highly hydrophobic one is preferable. However, the use of a material having a high content of triglyceride and diglyceride and high hydrophobicity deteriorates the solution stability of the composition, impairs the detergency and foaming power, and further enhances the oily feeling and the usability. Therefore, the glycerin fatty acid ester has an appropriately balanced hydrophobicity / hydrophilicity, that is, the fatty acid residue has 16 to 24 carbon atoms, particularly 16 to 22 carbon atoms, and the monoglyceride content is 75.
It is preferably about 100% by weight. The component (c) is contained in the detergent composition in an amount of 1 to 20% by weight, preferably 3 to 15% by weight. If this amount is less than 1% by weight, the above-mentioned effect is small, and if it exceeds 20% by weight, an oily feeling is strengthened, which is not preferable.

In the detergent composition of the present invention, in order to enhance the persistence of the component (c) on the skin and not to impair the detergency and foaming ability, which are the basic performances as a detergent, the above-mentioned 3
It is necessary to adjust the compounding ratio of the components. That is,
The total of the components (a) and (b) is 5 to 40% by weight. If the content is less than 5% by weight, the detergency and foaming power are insufficient, and if it exceeds 40% by weight, the solution stability becomes poor. It is not preferable because it is significantly impaired. The particularly preferred content is 10 to 30% by weight. Further, the components (a) to (c) are (c) / [(a) + (b)] = 0.05 to 1 (weight ratio).
It is necessary to be, and preferably 0.1 to 0.5. If it is less than 0.05, the persistence of the component (c) on the skin is reduced, and if it exceeds 1, the detergency and foaming power are impaired, which is not preferable.

In addition to the above-mentioned essential components, the cleaning composition of the present invention may contain various components, if necessary, within a range that does not impair the intended performance. Examples of the surfactant include nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene alkylphenyl ether, and fatty acid alkanolamide, and amphoteric surfactants such as alkyl betaine and alkyl sulfobetaine. As the solubilizer used in the liquid detergent, ethanol, lower alcohols such as isopropanol, polyhydric alcohols such as ethylene glycol, propylene glycol, glycerin, and sorbitol,
Aromatic sulfonates such as p-toluene sulfonate and m-xylene sulfonate are mentioned. Also, fragrance,
Dyes, antiseptic / antifungal agents, thickeners and the like can be added as desired.
