2. Description of the Related Art In general, household cleaning agents are widely used for various purposes, such as furniture, glass and oil stains, toilets and bathrooms. In particular, dirt generated in kitchens and homes of ordinary households is oxidized or polymerized by oxygen or heat in the air when left untreated, and changes to dirt that is difficult to remove. In order to remove the dirt in this state,
It is common to use a detergent containing an alkaline substance.

[0003] As these alkaline range cleaning agents,
For example, JP-A-3-41200, JP-A-5-50
Japanese Patent No. 3547 discloses a detergent comprising an alkaline substance such as an alkanolamine, an amphoteric detergent surfactant, and an anionic surfactant ammonium salt. In addition, these detergents, when used, diluted in water, rags,
There are two types of cleaning agents: a dip type that wipes off dirt attached to the item to be washed using a mop, etc. and a spray type that sprays directly onto the item to be washed or uses a rag to wipe off the dirt attached to the item to be washed. It is widely marketed, and recently a spray-type cleaning agent using a trigger container has become mainstream.

[0004] However, such a trigger spray type cleaning agent does not have sufficient cleaning performance for denatured dirt, and severe dirt is removed by repeated use. It is the current situation. Therefore, in order to exhibit excellent cleaning performance against highly denatured soil, measures to extend the residence time of the soil and the cleaning agent and improving the permeability to the soil greatly improve the cleaning performance. Become.

Therefore, Japanese Patent Application Laid-Open No. Hei 8-259997 discloses excellent foam performance (foam is sufficiently formed, hardly disappears, and hardly drools) by combining a fatty acid and a nonionic surfactant in addition to an alkali agent and a solvent. Although a composition having the same is disclosed, the technology disclosed in this publication is an improvement of only a measure for extending the residence time with the above-mentioned dirt, and it has an aspect of a cleaning performance against various types of dirt over time and a bubble performance that is easy to wipe off. There is a problem in that it is insufficient.

In the general formula (III), R ₅ is 6 to 24.
And an alkyl or alkenyl group having 10 to 18 carbon atoms is preferred. M is 1 or 2. Specific examples of the N-alkyl or alkenyl amino acid represented by the general formula (III) or a salt thereof include N-decylglycine, N-laurylglycine, N-
Myristyl glycine, N-palmityl glycine, N-decyl β-alanine, N-lauryl β-alanine, N-myristyl β-alanine, N-palmityl β-alanine, and salts thereof, but the present invention is not limited thereto. Not something. Specific examples of M ₁ in the general formula (III) include hydrogen, sodium, potassium, monoethanolamine, diethanolamine, triethanolamine and the like, but the present invention is not limited thereto. The method for producing these N-alkyl or alkenyl amino acids or salts thereof is not particularly limited, and can be produced by a conventionally known method. These N-alkyl or alkenyl amino acids or salts thereof can be used alone or in combination of two or more kinds.
0.1 to 10% by mass, and preferably 0.5 to 5% by mass, based on the total amount of the composition). When the amount of the component (a) is less than 0.1% by mass,
The surfactant has insufficient emulsifying and dispersing action and solubilizing action. On the other hand, if the content exceeds 10% by mass, no remarkable improvement in detergency can be expected, and on the contrary, the wiping property is deteriorated.

The component (b) of the first invention is used alternatively to the component (a), and the component (b) is an alkyl ethoxy sulfate represented by the general formula (I) or a component thereof. R ₁ in the salt is a linear or branched primary alkyl group or alkenyl group having 6 to 24 carbon atoms, and more preferably 10 to 18 carbon atoms.
When the number of carbon atoms is less than 6, sufficient detergency cannot be obtained due to insufficient hydrophobicity, and when the number of carbon atoms exceeds 24, the solubility of the surfactant itself decreases, so that precipitation occurs during storage. Cheap. Illustrative examples of preferred alkyl or alkenyl groups include hexyl, octyl, decyl, dodecyl, myristyl, palmityl, stearyl, oleyl, aralkyl, and benzyl. It is not limited to these. These alkyl groups or alkenyl groups may be used alone or as a mixture, and may be natural or synthetic.

In the alkyl ethoxy sulfate or its salt represented by the above general formula (I), which is the component (b) of the first invention, n represents the average number of moles of ethylene oxide group added, and , More preferably 1.5 to
4, more preferably in the range of 2-3. When n is less than 1, there is a problem that the content of the alkyl sulfate in which the number of moles of ethylene oxide added is 0 becomes too large, and it becomes difficult to wipe off. Conversely, if n is greater than 6, the detergency and foam performance cannot be satisfied. Also, n is not unique, and therefore, this component (b) contains alkylene oxysulfate having a different ethylene oxide addition mole number, that is, an alkyl ethoxy sulfate having a distribution,
The alkyl ethoxy sulfate of the present invention has the following characteristics in its distribution. First, the mass% occupied by the ethylene oxide addition mole number of 0 does not show the maximum value,
That is, it is a feature that the alkyl sulfate having a disadvantage in wiping properties is not most contained. In addition, a narrow distribution of alkyl ethoxy sulfate or a salt thereof having a maximum value of 15 to 35% by mass of the ethylene oxide adduct and a total amount of 55 to 75% by mass of the ethylene oxide adduct before and after the addition is 55 to 35% by mass. The feature that there is is also essential. In other words, the component (b) used in the present invention is, as it were, a purified alkyl ethoxy sulfate which is concentrated in a structure suitable as a main substrate of a hard surface cleaning agent.

Is also good.

The amount of the component (b) is from 0.1 to 10% by mass, preferably from 0.5 to 5% by mass, based on the total amount of the composition. When the amount of the component (b) is less than 0.1% by mass, the emulsifying / dispersing effect and solubilizing effect of the surfactant are not sufficient. Since no significant improvement can be expected, the wiping property is rather deteriorated.
