[0002]

2. Description of the Related Art Conventionally, alkyl sulfates have been used in detergents such as cleansing foams, body shampoos and shampoos from the viewpoints of foaming and usability. In particular, hair washed with alkyl sulfate does not have a squeaky feeling,
Shampoos have long been used as main bases.
On the other hand, it is also used in cleansing foams and body shampoos, but is mainly used not as a main base but as an auxiliary for imparting foaming power. This is because a slimy feeling is caused in the use feeling, and if a refreshing feeling can be imparted to the alkyl sulfate, the application range is further expanded.

[0003]

As described above, alkyl sulfates have excellent properties such as good bubbling, so that they can be used as a main base in detergents other than shampoos as long as they can give a refreshing feeling. By doing so, it is possible to obtain a cleaning agent with good foaming.

Accordingly, an object of the present invention is to provide a detergent composition which has good foaming and does not give a slimy feeling after use.
