Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition. The present detergent composition has good foaming properties, is less irritating to hair and skin, and is useful as a hair, body, textile and various household detergent. 2. Description of the Related Art Liquid detergent compositions based on an anionic surfactant having a low viscosity are generally low-irritating and have good low-temperature stability, but have an appropriate degree of moderateness required for their use. It was difficult to give the viscosity. There is a method of using an inorganic thickener in order to solve such a drawback. However, when a large amount of the inorganic thickener is added, the low-temperature stability is reduced. When a polymer thickener is used, the transparency of the system is often impaired. Further, in order to obtain a target viscosity, a method of using a hardly thickening anionic surfactant and a sulfate-type anionic surfactant in combination has also been tried. Was also not satisfactory.
