A foundation cream/liquid with a controllable color change and a preparation method firstly provides a pre-mixed powder for color-changeable foundation cream/liquid, including titanium dioxide and an inorganic pigment, wherein the titanium dioxide is processed with a methyl triethoxy silanization surface treatment; the inorganic pigment is processed with an octyl triethoxy silanization surface treatment. According to the present invention, totally different surface treatments are provided to the titanium dioxide and the inorganic pigment (iron oxide) in the foundation cream/liquid, in such a manner that surface properties of such two kinds of powder are quite different. A color changing effect of the color-changeable foundation cream/liquid prepared with the pre-mixed powder is controllable and rapid; a covering ability is strong; colors are varied; safety and harmlessness are guaranteed; and preparation is simple. |
