2. Description of the Related Art Generally, anionic surfactants such as higher fatty acid salts (soaps), alkylsulfates and sulfonates are often used as a main base in detergent compositions. However, when a higher fatty acid salt (soap) is used as a skin cleanser, soap scum (higher fatty acid Ca
However, there is a drawback in that it produces salt and the like and adheres to the skin, causing a squeaky and tight feeling. In order to improve this, an attempt has been made to blend an oil component such as a higher alcohol or a moisturizer such as propylene glycol, but the desired effect cannot be obtained with a small amount of the formulation, and when a large amount is blended, foaming occurs. However, there is a drawback that it is significantly inhibited. Therefore, an anionic surfactant that does not generate soap scum is being studied, but the desired effect cannot be obtained with a small amount of the compound, and when it is compounded in a large amount, defoaming becomes poor and slimyness occurs. I have a problem. On the other hand, when an alkylsulfate, a sulfonate or the like is used for hair washing, it does not have a squeaky feeling or a tightness, but it has drawbacks such as poor foam breakage and poor sliding of hair. Therefore, in order to improve these, blending of oil components such as higher alcohols, hydrocarbons and silicones has been studied, but the desired effect cannot be obtained with a small amount of blending, and foaming becomes poor when blending in a large amount. There is a problem such as becoming. Therefore, in order to solve these problems, it is considered to use a specific N-acyl amino acid type surfactant having an excellent feeling of use as a main base of a detergent (Japanese Patent Laid-Open Nos. 50-150701 and 63-63). 2962), but when the N-acyl amino acid type surfactant was used as the main base of the detergent, the foaming power was not sufficiently satisfactory.
