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 cleanability and foaming properties on these hard surfaces, but also does not cause redeposition of stains 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, there is a problem that oily stains are more likely to redeposit on the surface to be cleaned, which is a problem. Therefore,
There has been a demand for a detergent composition which has excellent detergency and foaming power, does not cause redeposition of stains, and is mild and does not cause rough skin.

[0007]

Under such circumstances, the present inventors have conducted diligent research to improve the above-mentioned problems, and as a result, have found that a composition containing an alkyl glycoside and an ethylene oxide addition type nonionic surfactant. If a certain amount of specific glycerin fatty acid ester is blended into the product, the detergency,
The present invention has been completed by finding that a hard surface cleaning composition excellent in foaming power, causing no redeposition of dirt, and mild to the skin can be obtained.

That is, the present invention provides the following components (a)-
(C) (a) The following general formula (1) R ¹ (OR ² ) _x G _y (1) (In the formula, R ¹ is a linear or branched alkyl, alkenyl or alkyl having 8 to 18 carbon atoms. Represents a phenyl group, R ² represents an alkylene group having 2 to 4 carbon atoms, G represents a residue derived from a reducing sugar having 5 to 6 carbon atoms, and x represents a number having an average value of 0 to 5 , Y represents a number whose average value is 1.0 to 1.42) 1 to 40% by weight (b) an ethylene oxide addition type nonionic surfactant 1 to 40% by weight (c) The fatty acid residue has 16 to 24 carbon atoms, and contains 1 to 20% by weight of glycerin fatty acid ester having a monoglyceride content of 75 to 100%, and the weight ratio of components (a) to (c) is (B) /
(A) = 0.05-1 and (a) + (b) = 5-4
0% by weight, and (c) / [(a) + (b)] =
The present invention provides a milky liquid hard surface cleaner composition having a concentration of 0.05 to 1.

The component (a) used in the present invention is an alkyl glycoside represented by the above general formula (1),
In the formula, R ¹ is a linear or branched alkyl, alkenyl or alkylphenyl group having 8 to 18 carbon atoms, and the number of carbon atoms is preferably 1 because of its solubility, foamability and detergency.
0 to 14. R ² is an alkylene group having 2 to 4 carbon atoms, but has 2 carbon atoms from the viewpoint of solubility in water.
Alkylene groups of 3 are preferred. Further, the structure of G is determined by the raw material of monosaccharide or disaccharide or more. Examples of the raw material of G include glucose, galactose, xylose, mannose, lyxose, arabinose and the like, and a mixture thereof. For disaccharides or more, maltose, xylobiose, gentibiose, lactose, sucrose, nigerose, turanose, raffinose, gentianose, melezitose and the like, and mixtures thereof can be mentioned. Of these, preferred monosaccharide raw materials are
Glucose and fructose are available due to their availability and low cost, and maltose and sucrose are used for two or more sugars.

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.
In the present invention, the measuring method of y 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.

Examples of the (b) component ethylene oxide addition type nonionic surfactant used in the present invention include polyoxyethylene alkyl ether, polyoxyethylene alkylphenyl ether, polyoxyethylene sorbitan fatty acid ester and polyoxy. Examples thereof include ethylene sorbit fatty acid ester, polyethylene glycol fatty acid ester, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene castor oil, polyoxyethylene hydrogenated castor oil, and polyoxyethylene / polyoxypropylene block polymer.
These ethylene oxide addition type nonionic surfactants are not particularly limited, but in the present invention, H
Those with LB = 10 to 15 are particularly preferable. The component (b) is preferably contained in the detergent composition of the present invention in an amount of 1 to 40% by weight, particularly 2 to 10% 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, if a material having a high content of triglyceride and diglyceride and a strong hydrophobicity is used,
The solution stability of the composition is deteriorated, the detergency and the foaming power are impaired, the oily feeling is further enhanced, and the usability is deteriorated. For this reason,
The glycerin fatty acid ester has an appropriately balanced hydrophobicity / hydrophilicity, that is, a fatty acid residue having 16 to 24 carbon atoms, particularly 16 to 22 carbon atoms, and a monoglyceride content of 75 to 100% by weight. Is preferred. The component (c) is contained in the detergent composition in an amount of 1 to 20% by weight, preferably 3 to 15% by weight. This amount is 1% by weight
If it is less than 20% by weight, the above-mentioned effects are 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 preferable content rate is 1
It is 0 to 30% by weight.

The weight ratio of the components (a) and (b), that is, (a) / (b), is required to be 0.05 to 1. If this ratio is less than 0.05, redeposition of stains may occur, and if it exceeds 1, foaming deteriorates, which is not preferable. Particularly preferred range is 0.1-0.5
Is. Furthermore, the components (a) to (c) are (c) /
[(A) + (b)] is 0.05 to 1, which is 0.
When it is less than 05, the residual property of the component (c) on the skin is lowered and the skin protecting ability is lowered, and when it is more than 1, it is unfavorable because the detergency and foaming ability are impaired. A particularly preferable ratio is 0.1 to 0.5.

In addition to the above-mentioned essential components, the detergent composition of the present invention may contain various components as required, as long as the desired performance is not impaired. For example, as the surfactant, anionic surface active agents such as polyoxyethylene alkyl ether sulfate, linear alkylbenzene sulfonate, α-sulfo fatty acid ester salt, α-olefin sulfonate, alkane sulfonate, and soap are used. Agent,
Fatty acid alkanolamide, tertiary amine oxide,
Examples thereof include nitrogen-containing nonionic or amphoteric surfactants such as alkylbetaine and alkylsulfobetaine. Also,
Examples of the solubilizing agent used in the liquid detergent include lower alcohols such as ethanol and isopropanol, polyhydric alcohols such as ethylene glycol, propylene glycol, glycerin and sorbitol, p-toluenesulfonate and m-xylenesulfonate. Aromatic sulfonates and the like. Further, fragrances, pigments, antiseptic / antifungal agents, thickeners and the like can be added as desired.
