Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cleaning agent, and more particularly to a cleaning agent useful for stabilizing a pearlescent agent.

[0002]

2. Description of the Related Art In the field of detergents such as rinses, shampoos and body shampoos, a pearl agent having a glittering appearance is often included from the viewpoint of beauty. The present inventors have found that such a pearly feeling not only has a beautiful appearance but also has an effect of realizing a cleaning effect. Such pearlescent agents include:
There are diesters and monoesters such as ethylene glycol, diethylene glycol or triethylene glycol, titanium mica, bismuth oxychloride, etc., but since the appearance of the pearl does not remain after washing, ethylene glycol, diester such as diethylene glycol or triethylene glycol or Monoesters are frequently used. Such a pearl agent exhibits a pearly feeling due to the optical effect of the precipitation of fine crystals, but such precipitated fine crystals are often unstable over time and are placed in a high temperature place such as a bathroom. In some cases, pearls settled and the appearance was sometimes impaired. For this reason, stabilization of the pearl agent was attempted using a surfactant such as coconut oil fatty acid diethanolamide, but for example, a stable agent was not obtained under severe conditions such as a temperature condition of 50 ° C. At present, it is handled by usage, such as displaying a message such as "Do not place in a hot place."
