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 the foamability of the hair, changes in the feeling after washing, that is, squeaky or lumpy hair, powderyness, and the like. Further, when a phosphate ester-based 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.
