COLORED NANOPARTICLES FOR COSMETIC AND ITS MANUFACTURING METHOD

摘要

<P>PROBLEM TO BE SOLVED: To provide a colored nanoparticle for cosmetics, its manufacturing method and its application. Ž<P>SOLUTION: The nanoparticle for coloring cosmetics is constituted by arbitrarily combining noble metal nanoparticles having a specific color tone and a specific saturation controlled to have a predetermined absorption spectrum within the wavelength range of 390-1,100 nm to permit selection of color tones and saturation based on morphological characteristics such as a particle size or a shape of the noble metal nanoparticles causing plasmon resonance characteristics. The manufacturing method of such nanoparticles for coloring cosmetics and cosmetics comprising such nanoparticles are also provided. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
