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.

[0002]

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, a higher fatty acid alkanolamide or an alkyl betaine, has been used. What was used in combination with a genital surfactant was used.

However, although the action of the anionic surfactant, which is the main base, on the skin of such a detergent composition has been moderated to some extent, it has not yet reached a satisfactory level. This is a problem because the sebum component of the skin is removed and the hand feels worse after use, such as a tighter hand. 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.

[0005]

Under such circumstances, the inventors of the present invention have conducted diligent research to solve the above-mentioned problems, and as a result, have identified a specific anionic surfactant and a specific tertiary amine oxide. It has been found that if a certain amount of glycerin fatty acid ester is blended, it is possible to obtain a hard surface detergent composition which is excellent in detergency and foaming power, does not cause rough hands, and has a good feel of hand skin after washing. completed.

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

R ⁶ O (R ⁷ O) _m SO ₃ M (2) (In the formula, R ⁶ represents an alkyl group or an alkenyl group having 10 to 18 carbon atoms, R ⁷ represents an alkylene group having 2 to 3 carbon atoms, m represents a number of 0 to 7, and M represents an alkali metal, an alkaline earth metal, ammonium, or an alkanolamine. (2) An alkylbenzene sulfonate represented by the general formula (3).

(In the formula, R ⁸ represents an alkyl group or an alkenyl group having 8 to 18 carbon atoms, and M ¹ represents an alkali metal, an alkaline earth metal, ammonium or an alkanolamine.)

(3) An α-sulfofatty acid ester salt represented by the general formula (4).

[Chemical 4]

(In the formula, R ⁹ represents an alkyl group or an alkenyl group having 8 to 18 carbon atoms, R ¹⁰ represents an alkyl group having 1 to 3 carbon atoms, M ² is an alkali metal, an alkaline earth metal or ammonium. Or alkanolamine)

(4) An α-olefin 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. (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 (a) is blended in the detergent composition of the present invention in an amount of 1 to 40% by weight, preferably 10 to 30% by weight. If the blending amount is less than 1% by weight, the detergency and foaming ability will be insufficient,
If it exceeds 5% by weight, the solution stability is significantly deteriorated, which is not preferable.

The tertiary amine oxide as the component (b) is
It is represented by the general formula (1), and when used in combination with the anionic surfactant as the component (a), it exerts the effects of enhancing the foaming power and relaxing the action on the skin. In order to exhibit this effect, the component (b) must be blended in the composition in an amount of 1% by weight or more. On the other hand, if the blending amount exceeds 20% by weight, the solution stability is significantly deteriorated, which is not preferable. Particularly preferable blending amount is 1 to 10% by weight.
Is. The weight ratio (b) / (a) with the component (a) is
It is preferably 0.1 to 0.3 in order to achieve the above effects.

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 1 to 20% by weight, preferably 3 to 15% by weight in the detergent composition.
Include it. 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 order to enhance the persistence of the component (c) on the skin in the cleansing composition of the present invention and not to impair the cleansing power and foaming power which are the basic performances as a cleansing agent, the above-mentioned 3
It is necessary to adjust the compounding ratio of the components. That is,
The total amount 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 40% by weight is markedly impaired in solution stability. It is not preferable because Incidentally, a particularly preferable content rate is 10 to 30.
% By weight. Further, the components (a) to (c) are (c) /
[(A) + (b)] = 0.05 to 1 (weight ratio) is necessary, and a particularly preferable ratio is 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 detergent composition of the present invention may contain various components as required 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,
