DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition, and more particularly to a detergent composition which is excellent in foam feel, detergency and foaming property, and can stably incorporate a cationic bactericide, and has a high sterilizing property. The present invention relates to a detergent composition suitable for skin, which can provide antipruritic and deodorant effects to the body so as to exhibit an antibacterial effect.

[0002]

2. Description of the Related Art Conventionally, cleaning agents, especially skin cleaning agents, include:
Because of its excellent detergency and foaming power, many anionic surfactants use a higher fatty acid salt as a main base, but the higher fatty acid salt alone has excellent foaming power, but Felt unsatisfactory.

On the other hand, many detergents having a bactericidal effect have been studied, and those using a cationic bactericide as a bactericide are known. However, when a cationic bactericide according to a detergent containing an anionic surfactant as a main base is mixed, a bactericidal effect is formed because a complex of the cationic bactericide and the anionic surfactant is formed. There are problems such as insufficient expression and impairment of the foaming properties of anionic surfactants.

[0004] As a method of preventing such a decrease in activity,
A method of coating a cationic bactericide with a high-molecular nonionic surfactant or a pH-sensitive polymer, a method of adding a large excess of a cationic bactericide, and the like have been adopted. However, in the former polymer coating method, the activity of the cationic bactericide decreases, while the method using an excess amount is not economically preferable.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide not only excellent cleaning properties and foaming properties, but also, particularly, excellent foam feel and stable stabilization of a cationic disinfectant.
It is an object of the present invention to provide a detergent composition which is capable of imparting an antipruritic effect and an odor preventing effect by obtaining a high bactericidal effect and an antibacterial effect.

A surfactant, an alkanolamide-based surfactant and an amide amino acid-based surfactant are blended in a specific amount or a combination of one or more selected from two or more,
Furthermore, when higher fatty acid is combined with higher fatty acid salt in a specific ratio, it has high detergency, high foaming property, good foam feeling, and sufficient bactericidal / antibacterial properties, antipruritic property, and deodorant effect. The present inventors have found that a cleansing composition suitable for use on the skin can be provided, and have completed the present invention.
