DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition which is excellent in foaming performance, has a suitable liquid property, and has a good feeling in use.

[0002]

2. Description of the Related Art In a liquid detergent using water as a medium,
It is important to optimize the liquid properties in addition to the detergency, foam performance, and feeling of use. Viscosity is used as an indicator of liquidity, but if the viscosity is too high, it will be difficult to get out of the container, or when applied to hair or body, it will be poorly stretched and it will not fit easily, and conversely, if the viscosity is too low, it will be picked up by hand Sometimes it is easy to spill, making it difficult to use. Alcohols, salts, polymers, and the like are used to adjust each product to an optimum viscosity. However, even when these are used, it is difficult to obtain the optimum viscosity range, and even if the viscosity can be adjusted, the foaming performance and the usability may be inferior. In addition, the anionic surfactant widely used as a cleaning component has a drastic reduction in foaming performance when oil stains are present. Various foaming agents are used in combination to supplement foaming performance.However, some foaming agents have a problem that the viscosity of the composition becomes high due to strong interaction with an anionic surfactant. Was.
