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 whiteness of the foundation cream is low, which affects consumers' desire to buy

Embodiment 1

[0087] The surface treatment of embodiment 1 titanium dioxide

Embodiment 1a

[0088] Example 1a Surface treatment of titanium dioxide using triethoxymethylsilane as the first siloxane surface treatment agent

[0089] Mix 0.45 kg of triethoxymethylsilane (ie, n1=2, a1=1 in formula (A)) and 1.05 kg of ethanol (95%) to prepare the first surface treatment solution. Ready to use.

[0090] Add 15kg of titanium dioxide into the mixer, and under stirring, spray the pre-prepared first surface treatment solution into the mixer and stir thoroughly, so that the first surface reaction solution and titanium dioxide are evenly mixed to obtain the first powder.

[0091] The first powder was discharged, immediately put into an oven, baked at 105° C. for 4 hours, cooled naturally and discharged.

[0092] The reaction process comprises the steps: (1) triethoxymethylsilane hydrolysis see Figure 2A and (2) hydroxyl condensation dehydration see Figure 2B . After treatment, the surface properties of the obtained titania powders can be found in Figure 2C . After treat...

Embodiment 1c

[0096] Embodiment 1c uses polymethylsiloxane (n) shown in formula (C) 3 =25) Surface treatment of titanium dioxide as the first siloxane surface treatment agent

[0097] The titanium dioxide of 15kg is added stirrer, under stirring, the polymethylsiloxane (n) shown in the formula (C) of 0.45kg 3 =25) Spray into a blender and stir well, so that the polymethylsiloxane and titanium dioxide are evenly mixed to obtain the first powder.

[0098] The first powder was discharged, immediately put into an oven, baked at 105° C. for 4 hours, cooled naturally and discharged.

[0099] The reaction process is as follows Figure 3A shown. The surface chemical properties of titanium dioxide powder after treatment are as follows: Figure 3B shown. After treatment by this method, the surface of titanium dioxide powder is covered with Si-O linear chain and -CH 3 The two groups of branched chains are evenly wrapped.

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 a first siloxane surface treating agent, the surface of the inorganic pigment is treated by using a second siloxane surface treating agent, the first siloxane surface treating agent is selected from, and the second siloxane surface treating agent is second siloxane of with carbon atom number greater than 1. 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 light to dark, 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...
