し易いなど経時安定性にも問題があった。2. Description of the Related Art Conventionally, the main ingredients of skin cleansing agents such as body shampoo and facial cleanser are higher fatty acid alkali salts (soap).
Met. Soap is still widely used because it has a unique refreshing feeling after washing and has good biodegradability and is a cleaning base that is environmentally friendly. However, a tingling sensation may remain after washing, and since the aqueous solution thereof is alkaline, it has been pointed out recently that it is irritating to the skin. Further, there is a problem in stability over time such that color burn is likely to occur.

提案されている。Therefore, anionic surfactants such as acyl amino acid salt, acyl methyl taurine salt, amide ether sulfate ester salt and amides which are mild synthetic surfactants which are said to be "mild to the skin etc." Amphoteric surfactants such as propyldimethylaminoacetic acid betaine, amide amino acid salt, and alkyliminodicarboxylic acid salt are often used. However, these synthetic surfactants may cause an unpleasant "slickness" at the time of rinsing and impair the refreshing feeling. Especially, it is difficult for Japanese people to wash their bodies, and at present, they are used in combination with soap. Is common. Therefore, in recent years, by combining various synthetic surfactants, the pH is weakly acidic,
Various types of hypoallergenic skin cleansing agents have been proposed that suppress the slimy feel during rinsing.

できていない。For example, Japanese Unexamined Patent Publication (Kokai) No. 62-226921 discloses a skin cleansing agent in which an acylamino acid salt, an acylmethyl taurine salt and a polyhydric alcohol are combined.
Japanese Patent No. 40850 discloses a cleansing composition in which an acyl lactylate is combined with an acylmethyl taurine salt, an alkyl ether sulfate, etc.
No. 25695 discloses a detergent composition in which an acylamino acid salt and an ethercarboxylic acid salt are combined.
Japanese Patent No. 3993 discloses a mild detergent composition in which amidopropyl betaine having a specific alkyl chain and an ether carboxylate are combined. However, these compositions not only have a slight slimy feel at the time of rinsing, but also have inferior foaming properties and foam qualities as compared with compositions containing soap, and moreover, they do not give a stick to the skin after washing.

ることは困難であった。Further, in recent years, a gel-like detergent composition has been favored from the viewpoint of appearance and usability. Carboxymethyl cellulose that is widely used to obtain a gel composition, hydroxyethyl cellulose, alkyl-modified carboxyvinyl polymer, water-soluble polymers such as xanthan gum have poor compatibility with various ionic surfactants, and There is a problem in that precipitation often occurs, and the feel of the product becomes poor, such as feeling slippery after washing. Polyoxyalkylene derivatives such as polyethylene glycol difatty acid ester and polyoxyethylene methyl glucoside fatty acid ester are also used for the purpose of increasing the viscosity of the detergent composition, but have a foaming property, a foam quality and a feeling of cleansing. Often has a negative effect,
Further, it has been difficult to keep the gel composition stable enough in viscosity for a long period of time.

In Comparative Example 3, since the component b was not blended, the foamability and foam quality were poor, there was sliminess during rinsing, and the feel of the skin after washing was poor. In Comparative Example 4, the blending amount of the component b was large, and thus the foam quality and stability over time were poor. In Comparative Example 5, since the amount of the component c was small, the stability over time and the low temperature storage stability were poor. In Comparative Example 6, since the amount of the component c was large, there was sliminess during rinsing and the feel of the skin after washing was poor.
