Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a detergent composition,
More specifically, it relates to a detergent composition having excellent detergency, less irritation to the skin and hair, and improved foamability, foam retention, foam quality and usability.

[0002]

2. Description of the Related Art Conventionally, detergent compositions mainly containing anionic surfactants such as shampoos, face soaps and kitchen detergents include higher fatty acid salts, polyoxyethylene alkyl ether sulfates and alkylbenzene sulfonates. It is used. However, the detergents containing these surfactants as the main components are excellent in detergency, but the squeaky feeling at the time of washing, the feeling of tightness after use, and the like are not sufficiently satisfactory, and further the skin and It has a problem of strong irritation to hair.

N-Long-chain acyl acidic amino acid salts and N-long-chain acyl neutral amino acid salts are known as surfactants which are less irritating to the skin and hair and have excellent detergency. A number of studies have been reported on the addition and blending of the above-mentioned detergent composition with the above-mentioned detergent composition (for example, "functional cosmetics" (published by CMC, page 275, 1990), Japanese Patent Laid-Open No. Hei 5).
No. 156281). In addition, Japanese Patent Publication Sho 39-2944
No. 4 discloses a mild detergent composition containing 1 to 50% by weight of an N-long-chain acyl threonine salt and an N-long-chain acylalanine salt with respect to a mineral oil type or alcohol-based synthetic detergent. However, there are problems in terms of usability such as foaming, squeaking during cleaning, and feeling after washing.
