Description

  The present invention relates to a shampoo composition.

Conventionally, in the field of detergents such as shampoos and body shampoos, the basic functions are detergency, foaming speed, foamy creaminess, smoothness of hair when rinsing, and softness of hair after drying. In addition, it is required to give a beautiful and sparkling appearance, that is, a high-class feeling.
Then, the shampoo composition containing a pearl pigment or ethylene glycol distearate etc. as a pearling agent which exhibits a high-class feeling is proposed (for example, refer patent documents 1-9).

  However, in these proposals, when the pearl pigment is contained, the shampoo composition can easily give a high-class feeling. However, the pearl pigment has a large specific gravity, and the dispersion stability with time deteriorates. As a result, there is a problem that it tends to impair the sense of quality. Further, when the ethylene glycol distearate is contained, the ethylene glycol distearate exhibits a pearly feeling due to an optical effect due to the precipitation of fine crystals, and therefore is inferior to the pearl pigment in terms of a high-quality feeling. There was a problem. Furthermore, the fine crystals tend to have poor temporal stability at high temperatures, and when they are placed in a high temperature place such as a bathroom, they settle and deteriorate the sense of quality.

  Therefore, it has good detergency, foaming speed, foam creaminess, smoothness of hair when rinsed, and softness of hair after drying, high quality, high temperature storage stability, and pearl when stored at high temperature. There has been a demand for a shampoo composition having excellent pigment dispersion stability.
