Title:
GARDENIA RED PIGMENT STABLY ADSORBED ON SURFACE OF SILICA, AND COSMETIC COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2019/199119
Kind Code:
A1
Abstract:
The present invention relates to a Gardenia red pigment stably adsorbed on the surface of silica, and a cosmetic composition containing same, and more specifically, to a Gardenia red pigment stably adsorbed on the surface of silica, the silica surface having a specific reactive group introduced thereto, and a cosmetic composition containing same. Compared to conventional Gardenia red pigments, the Gardenia red pigment stably adsorbed on the surface of silica, according to the present invention, has improved thermal stability, does not aggregate at a low pH level, and may be applied to cosmetic compositions other than water-phase cosmetic compositions, and thus can have a further expanded range of use.
