Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is characterized in that an anionic surfactant, an amphoteric surfactant and / or a semipolar surfactant, a higher fatty acid and a silicone derivative are blended. The present invention relates to a detergent composition which is excellent in stability and foamability during use and is excellent in imparting smoothness to hair and skin after use.

[0002]

PRIOR ART AND PROBLEMS Conventionally, quaternary nitrogen-containing water-soluble polymers have been used to impart smoothness to hair and skin in detergent compositions. These can impart smoothness during washing and rinsing, but the effect of imparting smoothness after use is difficult to recognize. In addition, various silicone derivatives have been used as components for improving smoothness. Since these have low compatibility with sweat and sebum, they have no sticky feeling and have the function of adsorbing to the surface of hair or skin to give a silky feeling and a smooth feeling. However, simply blending the silicone derivative into the detergent composition has a low adsorptivity to the surface of hair or skin, so that it is difficult to recognize a sufficient effect. In some cases, foaming during use and the stability of the system were not sufficient. The present invention has a technical problem to provide a detergent composition having excellent system stability, excellent foaming property during use, and excellent smoothness to the hair and skin after use. ..

Means for Solving the Problems As a result of intensive studies to achieve the above technical problems, the present inventors have found that anionic surfactants, amphoteric surfactants and / or semipolar surfactants are used. When blended with the above, a higher fatty acid, and a silicone derivative in the formulation of the detergent composition, the stability of the system and the foaming property during use are excellent, and it is excellent in imparting smoothness to the hair and skin after use. Based on this new finding, the present invention was completed based on the finding that a cleaning composition can be obtained.
