| titleOfInvention | Method for producing gold colloid |
| abstract | The colloidal gold has been studied for the purpose of obtaining a red color that does not fade, but the problem is the stability of the colloid, which usually requires a protective agent or stabilizer for the colloid. Although excellent in light resistance, color change and sedimentation are likely to occur in the liquid state due to the stability as a colloid. As a stabilizer to prevent this, strong emulsifiers are often used, which may limit the use as a pigment. SOLUTION: A certain period of time while warming chloroauric acid and chitosan. By a method of mixing and stirring and then using a reducing agent, a vivid pale red to reddish purple colloid solution can be obtained by a very simple method. In the present invention, a bright red system having extremely strong light resistance can be obtained by a simple method. The application range is not only promising as a raw material for cosmetics, but also uses no surfactant, so that safety is high and various applications can be considered. |
