Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition, and more particularly, to a cleaning composition which is less irritating to the skin and the like, has excellent foaming properties and detergency, and has a creamy foam and a good feeling upon use. Agent composition.

[0002]

2. Description of the Related Art Conventionally, as surfactants for detergents, anions such as alkyl sulfates, polyoxyethylene alkyl sulfates, alkylbenzene sulfonates, α-olefin sulfonates, etc., which have high foaming properties. Surfactants are widely used. However, these anionic surfactants have no problem in irritation as long as they are added to a normal detergent, but when the amount is increased to further increase the foaming power and detergency, There is room for improvement in terms of irritation.

[0003] As surfactants for detergents, amido-amino acid type surfactants having low irritation to skin and ocular mucosa, and amphoteric surfactants such as carbobetaine, sulfobetaine and imidazolinium betaine are also widely used. Used. However, these amphoteric surfactants have some difficulties, such as inferior detergency and foaming properties, which are essential properties required for a detergent composition, and are difficult to use as main activators. there were.

[0004] Thus, while the combination of an anionic surfactant and an amphoteric surfactant is used to achieve both low irritation and high foaming properties, it is apparent that irritation cannot be fundamentally improved. .

[0005] As low-irritating surfactants, alkyl saccharide-based surfactants, sulfosuccinic acid-based surfactants, ether carboxylic acid-based surfactants, amide ether carboxylic acid-based surfactants and the like are known. . However, although alkyl saccharide-based surfactants have high foaming properties, they have strong blemishes during washing and rinsing, and are therefore used in combination with a conditioning agent such as a cationic polymer (Japanese Patent Laid-Open No. 2-42013). Although it has been proposed, it is not technically easy to mix a large amount into a shampoo or the like. In addition, sulfosuccinic acid-based surfactants alone have poor foaming properties and may be used in combination with other surfactants (Japanese Patent Laid-Open No.
2-218797) and the like, and are often used in combination with other surfactants in practical use. Furthermore, commercially available ether carboxylic acid-based surfactants and amide ether carboxylic acid-based surfactants also have poor foaming properties, and are used only as auxiliary surfactants in detergents that require high foaming properties. ing.

[0006] As described above, low-irritating surfactants are generally excellent in safety and the like, but are still insufficient in detergency and foaming power, which are particularly important as detergents, and are themselves components such as shampoos. Is rarely used alone, and is generally used in combination with a conventional anionic surfactant such as alkyl sulfate and alkyl ether sulfate. On the other hand, sulfates of fatty acid monoethanolamide or isethionate are surfactants excellent in both safety and foaming properties, but have a problem in chemical stability in a solution state. Furthermore, as a mild and high foaming detergent, N-
Alkyl amide alkanol sulfates have been proposed, but there has been a demand for a detergent composition that is more improved in terms of foam quality and feel during use.

[0007]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a detergent composition which is less irritating to the skin, has excellent foaming properties and detergency, and has a creamy foam and a good feeling upon use. Is to do.

[0008]

Under such circumstances, the present inventors have conducted intensive studies. As a result, if a specific N-alkylamide alkanol sulfate salt and an amphoteric surfactant are used in combination, skin and the like can be obtained. The present inventors have found that a detergent composition having a low irritation, a high foaming property, a creamy foam, and a good feeling in use can be obtained, and the present invention has been completed.

That is, the present invention provides the following component (A) and
