Problems solved by technology

So it is difficult to achieve good hiding power
[0011] (2) Slow discoloration
Slow and gentle application is not conducive to the breaking of particles, which is not conducive to the appearance of discoloration effect
However, as a cosmetic for the face, the foundation cream / liquid is rarely applied repeatedly and quickly, which affects the speed and effect of the product's discoloration
[0012] (3) The production process is difficult to master
[0015] (2) The shiny effect of pearl powder is destined not to be used on the whole face
Can not play the role of covering blemishes and adjusting skin tone
[0018] (2) Harmful to the human body
However, although the liquid foundation / cream foundation provided in this application has a smooth skin feel, breathable and refreshing, but the moisturizing degree is not enough, especially when used in autumn and winter, it needs to be used with other skin care products
In addition, in the technical solution of this application, the discoloration effect is not ideal all the time, especially the discoloration effect is difficult to control. The distribution state (dispersion) in siloxane is controlled at certain points
According to the experimental results, if triethoxymethylsilane is used alone to treat iron oxide, the discoloration effect of the final foundation composition is always unsatisfactory, and the discoloration effect is difficult to control

Embodiment 1

[0085] Titanium dioxide surface treatment

[0086] Use triethoxyoctylsilane (that is, an alkylsiloxane having a structure shown in formula (A) and n'=8, a=1, m=2 to carry out surface treatment to titanium dioxide, and the treatment method is as follows:

[0087] Mix 0.45kg triethoxyoctylsilane and 1.05kg ethanol (95% by volume) aqueous solution evenly to prepare the first surface treatment solution, which is ready to use after mixing.

[0088] Add 15kg of titanium dioxide powder into the blender, and under high-speed stirring, spray the pre-prepared surface treatment liquid into the blender through the oil spray tank and fully stir, so that the first surface treatment liquid and titanium dioxide are evenly mixed, and the first powder.

[0089] The first powder was discharged, immediately put into an oven, baked at 105° C. for 4 hours, cooled naturally and discharged.

[0090] Surface treatment of iron oxide black

[0091] Mix 0.15kg of triethoxymethylsilane, 0.6kg of polydi...

Embodiment 2

[0099] Mix 0.45kg of triethoxymethylsilane with 1.05kg of 95% by volume ethanol aqueous solution to prepare the first surface treatment solution, ready to use;

[0100] Add 15kg of titanium dioxide into the blender, and under stirring, spray the prepared first surface treatment liquid into the blender, and stir thoroughly, so that the first surface treatment liquid and titanium dioxide are uniformly mixed to obtain the first powder. The first powder was discharged, immediately put into an oven, baked at 105° C. for 4 hours, cooled naturally to room temperature, and discharged to obtain titanium dioxide treated with triethoxymethylsilane.

[0101] Mix 0.45kg of triethoxyoctylsilane with 1.05kg of 95% by volume ethanol aqueous solution to prepare the second surface treatment solution, which is ready to use; 15kg of inorganic pigment iron oxide is added to the mixer, and under stirring, the Spray the above-mentioned second surface treatment liquid into the mixer, stir well, so th...

Embodiment 3

[0103] Prepare the color-changing foundation premix with the following proportioning ratio with titanium dioxide, iron oxide yellow, iron oxide black and iron oxide red prepared in Example 1:

[0104] component name CC603 ratio (%) CC605 ratio (%) CC807 ratio (%) CC808 ratio (%) Titanium dioxide 94 94 94 94 Iron oxide yellow 3.75 3.55 3.90 4.00 Iron Oxide Red 1.80 1.95 1.77 1.68 iron oxide black 0.45 0.50 0.33 0.32

Abstract

The invention relates to a foundation premix with color changing from shallow to deep. The foundation premix comprises titanium dioxide and inorganic pigment, the surface of titanium dioxide is treated by using (Cn'H2n'+1)aSi(OCmH2m+1)4-a (wherein n' is an integer and is greater than and equal to 1, m is 1 or 2, and a is an integer and is greater than or equal to 1 and less than or equal to 3), and the surface of the inorganic pigment is treated by using a compound treating agent comprising (CpH2p+1)bSi(OCqH2q+1)4-b (wherein p is an integer and is greater than and equal to 1, q is 1 or 2, and b is an integer and is greater than or equal to 1 and less than or equal to 3). The invention further relates to a preparation method of the foundation premix and the foundation composition comprising the foundation premix. The foundation composition has the advantages of controllable and quick color changing, high wettability, high covering ability, color diversity, safety, harmlessness, simple production process and high whiteness.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a foundation premix that changes color from deep to light, a foundation composition containing the foundation premix and a preparation method thereof. Background technique [0002] Foundation such as foundation cream / liquid is a very important cosmetic category, and it is also the basis for a good makeup effect. Cosmetics manufacturers usually provide foundations of different colors (such as dark skin and light skin) etc. according to the user's skin color. The appearance color of ordinary foundation cream is basically the same as the actual use color. [0003] In order to create novel visual effects and achieve the purpose of attracting consumers, new color-changing foundations have emerged in recent years. Discoloration usually occurs when the paste changes from a light color (such as off-white, white) to a darker color (such as dark skin, light skin) or from a dark color (such as da...
