Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a body shampoo,
Regarding skin cleansing agents such as hand soaps and facial cleansers, more specifically, it has excellent foaming properties and foam quality, and has an excellent feel during and after rinsing. It gives skin after washing, stability over time, and storage at low temperatures. The present invention relates to a hypoallergenic detergent composition having excellent properties.

[0002]

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. In addition, there was a problem with stability over time, such as color burns.

Therefore, anionic surfactants such as acylamino acid salt, acylmethyl taurine salt, amide ether sulfate ester salt and the like which are mild synthetic surfactants called "mild to the skin" and amidopropyl. Amphoteric surfactants such as dimethylaminoacetic 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, which may impair the refreshing feeling. In particular, 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, various hypoallergenic skin cleansing agents have been proposed which combine various synthetic surfactants and have a pH close to weak acidity and which suppresses slimy feeling during rinsing.

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 and the like, and JP-A-6-
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 are inferior in foamability and foam quality as compared with compositions containing soap, and moreover, they do not give a stick to the skin after washing. Not done.

[0005]

The present invention has solved the above-mentioned problems and has excellent foamability and foam quality, an excellent feeling during rinsing and after washing, gives a skin after washing, stability over time and It is an object of the present invention to provide a hypoallergenic detergent composition having excellent low temperature storage and restoration properties.
