2. Description of the Related Art In recent years, due to changes in lifestyle, the frequency of washing hair has increased, as typified by the "morning shan" boom centered on high school girls and young office workers. There is a need for detergent compositions that are irritating. Attempts have been made to use a mild surfactant as such a detergent composition, and examples of such a surfactant include an acylalkyl taurine salt type anionic surfactant.

As a detergent composition using an acylalkyl taurine salt type anionic surfactant, a detergent composition obtained by combining an aminoacetic acid betaine type amphoteric surfactant and an alkanolamide (Japanese Patent Publication No. 59-42038). Gazette), N- (2-alkyl-2-hydroxyethyl)-
A detergent composition in which N-methylaminoethanol phosphate ester salt is combined (Japanese Patent Publication No. 26672/1990),
Detergent composition combining amine oxide and alkanolamide (Japanese Patent Publication No. 26673/1990), detergent composition combining amidobetaine type amphoteric surfactant and alkanolamide (Japanese Patent Publication No. 26677/1990). , A detergent composition in which an amidoamino acid type amphoteric surfactant and an alkanolamide are combined (JP-A-60-1)
68795) and the like.

Further, in recent detergent compositions, especially hair shampoo compositions, the finish after washing the hair is emphasized, and the elements which have been required for the conditioners and conditioners have been required for the hair shampoos. It was As such a hair shampoo composition which attaches importance to the finish after washing the hair, a detergent composition in which a surfactant, polyacrylamide and a cationic polymer compound are combined (JP-A-62-167722), A detergent composition in which an anionic surfactant, a cationic polymer compound and a silicone derivative are combined (JP-A-56-72).
095), nonionic surfactants and imidazoline type quaternary ammonium salt type cationic surfactants or dialkyldipolyoxyethylene hydroxyethyl ammonium salt type cationic surfactants and carboxylate type anionic surfactants. Examples thereof include a detergent composition in which a surfactant is combined (JP-A-1-14496).

[0005]

A detergent composition using an acylalkyl taurine salt-type anionic surfactant has a low viscosity, so that it easily flows off when picked up.
Alternatively, it had the disadvantage of lacking in luxury. When the viscosity is adjusted by using a viscosity modifier, for example, an inorganic salt such as sodium chloride, the stability of the detergent composition with time decreases. Further, regarding the hair shampoo composition that emphasizes the finish after washing the hair, the one using a cationic polymer compound has a drawback that it is difficult to take a feeling of sliming at the time of rinsing and it takes time to rinse. The one using the silicone derivative has a drawback that the stability with time and the foaming property are deteriorated, and the one using the cationic surfactant is
Since there is a limitation on the compounding formulation, there is a drawback that the foaming property is lowered when the compounding amount is sufficient to give the hair sufficient flexibility. INDUSTRIAL APPLICABILITY The present invention is hypoallergenic, has excellent foaming property and rinsing property, has good finger passage during washing and rinsing, has an excellent conditioning effect after drying, and has an appropriate viscosity and is stable over time. An object of the present invention is to provide a detergent composition having good properties.
