DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition having low skin irritation, good foaming, excellent foam creaminess, and particularly excellent moist feeling in conditioning effect after washing.

[0002]

2. Description of the Related Art Conventionally, a cleaning composition which has excellent foaming and foam creaminess and a good conditioning effect after cleaning has been studied. For example, in order to improve the feeling of rinsing during hair washing, an attempt has been made to mix a cationic polymer such as cationic cellulose with a normal (single-chain, one-polar group-containing) anionic surfactant which is a main component of a hair cleansing agent. It has been recognized that this formulation improves the rinsing feel. This is because an anionic surfactant for hair washing such as polyoxyethylene lauryl ether sulfate or alkyl sulfate forms a complex salt with a cationic polymer at the time of rinsing and is adsorbed on the hair. On the other hand, the blending of the cationic polymer has disadvantages such as hardening of the hair at the time of rinsing or finishing. Therefore, recently, a hair cleansing agent containing an amphoteric surfactant and a specific amphoteric polymer has been studied. When this is used, the conditioning effect after washing is good, but the foaming and the creaminess of the foam are not sufficiently satisfied. In order to solve these problems, a combination of an amphoteric surfactant, a quaternary ammonium, and a carboxyl group-containing anionic surfactant (Japanese Patent Application Laid-Open No.
2-288694), nonionic surfactants, No. 4
Combinations of quaternary ammonium and a carboxyl group-containing anionic surfactant (JP-A-63-317596, JP-A-8-325595) have been proposed. However, these cleaning agents all foamed, and were not satisfactory in terms of foam creaminess. In addition, skin irritation was not sufficient. As described above, a cleaning composition having low skin irritation, good foaming, excellent foam creaminess, and a moist feeling as a conditioning effect after washing has not yet been developed. Was desired.

[0003]

The present inventor has made intensive studies to improve such disadvantages of the prior art, and as a result,
Specific acyl group 2 long chain bipolar group containing anionic surfactant, 1 chain 1 polar group containing anionic surfactant, nonionic surfactant, amphoteric surfactant, silicone polymer and / or hydroxyl group It has been found that the incorporation of a compound having at least two of the above in the molecule significantly improves the above disadvantages, and has led to the completion of the present invention. That is, an object of the present invention is to provide a detergent composition having low skin irritation, good foaming, excellent foam creaminess, and a moist feeling as a conditioning effect after washing.
