2. Description of the Related Art Conventionally, in a detergent composition used for cleaning skin and hair, such as a facial cleanser or a hair cleansing agent, a silicone is blended to, for example, function as a rinse-in shampoo in a hair cleansing agent. There is known a technique for improving the feeling of use of a hair treatment agent such as a hair rinse agent used after the hair has been washed or washed, and also has an effect of improving the makeup removing effect of a face wash. Also, it is known from Japanese Patent Publication No. 4-62288 and Japanese Patent Publication No. 7-80740 to mix silicone in a dispersed state as well as in an emulsified state.

However, the emulsified silicones are incorporated into the detergent composition using a long-chain acylsulfonic acid type surfactant such as acylmethyltaurine which is excellent in safety as a detergent base. In such a case, there is a problem that stability is deteriorated and commercialization is difficult. Therefore, there has been a demand for a detergent composition that satisfies both the improvement of the feel when used in combination with silicones and the securing of safety by the long-chain acylsulfonic acid type surfactant in various use modes.
