2. Description of the Related Art Many types of anionic surfactants are used as detergents because of their excellent surface activity. However, dish soap, body shampoo,
It is indispensable for the human body to be used in applications where it is premised that an aqueous solution of a surfactant such as shampoo comes into contact with the human body. As mild surfactants, amino acid-based,
Alkyl phosphates are used, but these activators are mild, but they do not always exhibit sufficient foaming power and detergency, and they also have the drawback of poor solubility. . A detergent composition containing an α-sulfofatty acid derivative-based surfactant is also known (Japanese Patent Laid-Open No. 6-6559).

A detergent composition is provided.

In the general formula (1) representing the α-sulfofatty acid derivative-based surfactant (a), R ¹ is a linear or branched alkyl group having 4 to 16 carbon atoms, preferably 8 to 14 carbon atoms. Is. As an alkyl group like this,
Examples thereof include a butyl group, a hexyl group, an octyl group, a dodecyl group, a tetradecyl group, and a hexadecyl group.
R ² is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms (eg, methyl group, ethyl group, propyl group). AO represents a lower alkyleneoxy group, and examples of the lower alkyleneoxy group include ethyleneoxy group, propyleneoxy group and butyleneoxy group.

M is a number of 1 or more, preferably 3 to
The number is 25, more preferably 5 to 15. M ¹ is a hydrogen atom or a salt-forming cation, and examples of the salt-forming cation include alkali metals such as sodium, potassium and lithium; alkaline earth metals such as magnesium; and unsubstituted or substituted ammonium. . Examples of the substituted ammonium include those derived from amines, preferably lower amines (trimethylamine, triethylamine, etc.),
Examples thereof include those derived from lysine, those derived from mono-, di- or tri-lower alkanolamines.

As the amphoteric surfactant (c), various conventionally known ones, for example, betaine type (C _10-18 ) alkyl betaine, amidopropyl betaine, imidazolinium betaine, sulfobetaine and the like can be mentioned. Also,
Examples of the semipolar surfactant (c) include various conventionally known compounds such as C _{8 to} C ₁₈ monolong-chain dimethylamine oxide.

The ratio of each surfactant used is as follows:
The amount of the α-sulfofatty acid derivative (a) is 10 to 90% by weight, preferably 20 to 80% by weight, based on the total amount of the surfactant (a + b + c), and the nonionic surfactant (b) is used.
Is 5 to 45% by weight, preferably 10 to 40% by weight, and the amphoteric surfactant and / or the semipolar surfactant is 5 to 45% by weight.
It is 45% by weight, preferably 10 to 20% by weight. When the proportion of the nonionic surfactant is less than the above range, the foaming power of the composition is lowered, while when it exceeds the above range, the fluidity of the liquid obtained by dissolving the composition in water is lowered. .
Further, when the proportion of the amphoteric surfactant and / or the semipolar surfactant is less than the above range, the cleaning performance of the composition is deteriorated, while when it is more than the above range, the composition is dissolved in water. Liquidity decreases.

In the composition of the present invention, in addition to the above-mentioned α-sulfofatty acid derivative-based surfactant, nonionic surfactant and amphoteric surfactant, components usually used as a detergent auxiliary component are added to the composition of the present invention. It may be optionally used in combination within a range that does not impair it. Examples of such auxiliary components include solvents, hydrotropes, bactericides, fragrances and pigments. The composition of the present invention is applied as a liquid detergent composition as it is or by dissolving it in water. In this case, the total surfactant concentration in the liquid is 2
It is preferable to set it to 0% by weight or more.

The detergent composition of the present invention was excellent in fluidity even at a high concentration, and was excellent in foaming property and cleaning performance even when using a high concentration stock solution or when diluted. The composition of the present invention can be applied to hard surfaces, wood surfaces, skin and hair. In this case, for hard surfaces, tableware, plastic surfaces, ceramic surfaces, etc. can be considered. The wooden surface may be the surface of furniture or a pillar. Therefore, the present invention can be applied as a cleaning agent for kitchen, a cleaning agent for home, and a shampoo.
