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 has a low irritation, excellent detergency and a good feeling after foaming, and a stable blending of a cationic germicide. To achieve high sterilization and antibacterial effects
The present invention relates to a detergent composition which can impart anti-itch and deodorant effects to the body and is particularly suitable for skin.

[0002]

2. Description of the Related Art Conventionally, cleaning agents, especially skin cleaning agents, include:
Because of their excellent detergency and foaming power, many anionic surfactants use higher fatty acid salts as the main base, but higher fatty acid salts alone cause high skin irritation,
After washing, there are defects such as rough skin and firmness of the skin.

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 a cationic bactericide which is excellent in detergency, foaming property and feeling after washing, has no feeling of tightness of the skin after washing, has low irritation, and is cationic. An object of the present invention is to provide a cleansing composition suitable for skin, which can be stably compounded, and can also provide an antipruritic property and an odor preventing effect by obtaining high bactericidal and antibacterial effects.

[0006]

The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that higher fatty acid salts, specific cationic bactericides, amphoteric surfactants, and amine oxide-based surfactants. Surfactants, alkanolamide-based surfactants and amide amino acid-based surfactants may be combined with one or more selected from two or more and a cationic polymer in a specific amount to provide high detergency, high foaming properties, The present inventors have found that a cleansing composition suitable for skin that is hypoallergenic, has excellent feel after washing, and can impart sufficient bactericidal and antibacterial properties, antipruritic property and deodorant effect can be obtained. completed.
