WET FORMING COLOR COSMETIC CONTAINING ORGANIC ULTRAVIOLET BLOCKING AGENT DEPOSITED ON HYDROPHOBIC-TREATED POROUS SILICA AND METHOD FOR PREPARING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a wet forming color cosmetic containing an organic ultraviolet blocking agent deposited on hydrophobic-treated porous silica and a method for preparing the same.SOLUTION: A wet forming color cosmetic containing an organic ultraviolet blocking agent deposited on hydrophobic-treated porous silica is obtained by hydrophobic treatment of the surface of the porous silica by silylation followed by the deposition of the organic ultraviolet blocking agent. Hydrophobic treatment of the surface of the porous silica can stabilize the deposited organic ultraviolet blocking agent and, when the organic ultraviolet blocking agent is dispersed with volatile solvents and dried for producing the wet forming color cosmetic, elimination of the organic ultraviolet blocking agent to the outside of the porous silica can be prevented and the stability of formulation can be ensured.
