Problems solved by technology

So it is difficult to achieve good hiding power
[0014] (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
[0017] (3) The production process is difficult to master
[0020] 2. Defects of color-changing pearl powder technology
[0024] (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
[0029] (2) Harmful to the human body

Embodiment 1

[0089] The process of triethoxymethyl silylation surface treatment of titanium dioxide:

[0090] Mix 0.45kg of triethoxymethylsilane with 1.05kg of 95% ethanol evenly to make a surface treatment solution, ready to use;

[0091] Add 15kg of titanium dioxide into the high-speed mixer, and under high-speed stirring, spray the above prepared surface treatment liquid into the high-speed mixer through the oil spray tank, and stir fully to make the reaction solution and titanium dioxide mix evenly;

[0092] The powder is discharged, immediately sent to the oven, baked at 105°C for 4 hours, and cooled naturally.

[0093] Triethoxyoctyl silylation surface treatment process of inorganic pigments:

[0094] Mix 0.45kg of triethoxyoctylsilane with 1.05kg of 95% ethanol evenly to make a surface treatment solution, ready to use;

[0095] Add 15kg of inorganic pigments into the high-speed mixer, and under high-speed stirring, spray the above prepared surface treatment liquid into the high-s...

Embodiment 2

[0097] Embodiment 2: Several color-changing powder premixes with different proportions: the following proportions are all mass percentages,

[0098]

[0099] The adjustment of the above ratio is only reflected in the color of the foundation product, which can be freely allocated according to the color of the foundation product required. Foundation products are the basis of makeup, and the content of titanium dioxide is usually between 75% and 95%. If it is too high, it will be too white, and if it is too low, the color will be too heavy, which is not conducive to achieving a good makeup effect.

Embodiment 3

[0100] Example 3: Color Changing Cream Foundation

[0101] Recipe composition:

[0102]

[0103]

[0104] Preparation Process:

[0105] 1. Mix and stir phase A, and homogenize for 1 minute to completely disperse the DC9040 silicone elastomer.

[0106] 2. Heat phase A to 55-60 degrees, add phase B powder, and homogenize for 1 minute to disperse the powder evenly.

[0107] 3. At the same time, heat phase C to about 55-60 degrees to dissolve completely.

[0108] 4. Speed ​​up the stirring speed of phase AB (200-300 rpm), slowly add phase C into phase AB to make the emulsification complete

[0109] 5. Stir and cool down to below 45 degrees, add phase D to make the paste white, and discharge.

[0110] 6. During the cooling process, the stirring speed is (200-300 rpm). Turns white in about 2-3 hours.

[0111] The foundation product of Example 3 of the present invention has an obvious discoloration effect during use, fast discoloration, strong hiding power, easy to apply ...

Abstract

The invention relates to controllable discolouring foundation cream / liquid foundation and a preparation method thereof. The preparation method of the controllable discolouring foundation cream / liquid foundation comprises the following steps: providing a powder premix compound containing titanium dioxide and inorganic pigment, for the coloured foundation cream / liquid foundation, wherein the titanium dioxide is subjected to triethoxy methyl silylation surface treatment, and the inorganic pigment is subjected to triethoxy octyl silylation surface treatment. The controllable discolouring foundation cream / liquid foundation has the advantages that completely different surface treatment methods are adopted for the titanium dioxide and inorganic pigment (ferric oxide) in the foundation cream / liquid foundation, so that surface properties of the two powders are obviously different;the discolouring foundation cream / liquid foundation prepared by utilizing the titanium dioxide and inorganic pigment is controllable and quick in discolouring effect; covering power is high; colours are diverse; the discolouring foundation cream / liquid foundation is safe and harmless; a production process is simple.

Description

technical field [0001] The invention relates to a cosmetic and a preparation method thereof, in particular to a foundation cream / liquid foundation with controllable discoloration and a preparation method thereof. Background technique [0002] Cream / liquid foundation is a very important category of cosmetics, 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 one color (such as light yellow) to another during application Co...
