[0002]

2. Description of the Related Art In recent years, a detergent composition has replaced a conventionally used soap, alkyl sulfate, alkyl ether sulfate or the like with a phosphate ester type surfactant having reduced skin irritation. Is becoming more common.

[0003]

However, the phosphoric acid ester-based surfactant easily binds to calcium ions in water and precipitates as a salt, and therefore, when water having particularly high hardness is used, washing is difficult. And foamability,
There is a drawback in that the feeling after washing is changed, that is, the hair feels squeaky or lumpy, and the hair becomes powdery. Also,
When a phosphate ester surfactant is used as a bathing agent together with a large amount of tap water, scum formation is conspicuous, and some people feel uncomfortable, which is a problem.

Therefore, it has been desired to develop a detergent composition which does not cause discomfort such as squeaking due to scum and has good detergency, foamability and feel after washing even when used with hard water or a large amount of water. It was

Therefore, an object of the present invention is to provide a detergent composition which has a low irritation, an excellent detergency and a refreshing feel.
