Estimating the term…
One aspect of the present disclosure relates to a gardenia red pigment stably adsorbed on the surface of silica, and a cosmetic composition containing the 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 the same. Compared to conventional gardenia red pigments, the gardenia red pigment stably adsorbed on the surface of silica, according to one aspect of the present disclosure, 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.
A silica-adsorbed gardenia red pigment, wherein the silica is surface-modified to contain a reactive group selected from the group consisting of an amine group, a carboxyl group, an ester group, a thiol group, a hydroxy group and hydrogen and wherein the gardenia red pigment is coupled to the reactive group.
