Description

A kind of light-sensitive whitening and skin brightening colorful cream and its preparation method

【Technical field】

The invention relates to a colorful cream, in particular to a light-sensitive whitening and skin brightening colorful cream. The invention also relates to a method for preparing the colorful cream, which belongs to the technical field of cosmetics.

【Background technique】

There are not many cream products on the market that can change color and moisturize, change and brighten the skin color. At present, some products that can change color on the market achieve the effect of color change by adding wrapped pigments and applying them to the skin to wrap the particles to break. However, due to the influence of stirring or shearing external force in the production and filling process of such products, the particles are likely to break. If the product has quality problems, at the same time, in the selection of packaging materials, it is also necessary to pay attention not to choose packaging that squeezes the material body, otherwise the material body will be crushed and discolored before being applied to the skin; another type is to add a product that is sensitive to pH The pigment changes the color of the product by applying it to the skin to change the pH value. When this type of product is produced, the pH value must be controlled at a low point. Storage tanks, filling machines, and packaging bottles must be pre-soaked with citric acid acid solution Treatment to make the part in contact with the material body acidic, otherwise the PH value will rise after the material body contacts, and the color will appear, resulting in abnormal material body.

【Content of invention】

The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a simple production process, use equipment and packaging materials without special treatment, stable properties, easy to use, the product presents one color before smearing, and another color when smeared on the skin. A radiant whitening and brightening cream that brightens the complexion in one color.

Another object of the present invention is to provide a preparation method of the colorful cream.

In order to achieve the above object, the present invention adopts the following technical solutions:

A light-sensitive, whitening, brightening and colorful cream is characterized in that it comprises the following components by weight percentage:

A. Oil phase component 9～43%

B. Water phase component 34.74～68.8%

C. Functional component 6.8～29.5%

D. Preservative component 0.3～1.4%

E. Flavor 0.01-0.3%.

A light-sensitive, whitening, brightening and colorful cream as described above is characterized in that the oil phase components include the following components by weight percentage:

A light-sensitive, whitening, brightening and colorful cream as described above is characterized in that the water phase components include the following components by weight percentage:

A light-sensitive, whitening, brightening and colorful cream as described above is characterized in that the functional components include the following components by weight percentage:

A light-sensing, whitening, skin-brightening and colorful cream as described above is characterized in that the interference color pearlescent pigment is mica titanium hydrochloride, and the mica titanium hydrochloride includes the following components in weight percent: tin dioxide 0.0- 1.0%, titanium dioxide 40.6-46.6%, mica 52.4-59.4%.

Pearlescent pigments are composed of thin layers of several metal oxides coated with mica. Different pearlescent effects can be produced by changing the thin layer of metal oxide. Compared with other pigments, pearlescent pigments have incomparable effects for their unique soft pearl luster. The special surface structure, high refractive index and good transparency make it create the same effect as pearl luster in a transparent medium.

Interfering pearlescent pigments, the transformation effect is produced by light interference, and the color produced by light reflection varies with the thickness of the coating. The incident light is reflected/refracted by the coating; part of the light (eg red) passes through the paint and the rest (in this case, green) is reflected, the background color should be taken into account since the interfering color is dichroic.

In the case where the background color is white, the complementary color of the transferred element is reflected by it and combined with the original reflected color to reduce the transformation effect at once.

When the background color is black, the transmitted complementary color is absorbed by it, and the original reflection color is obviously preserved. As mentioned above, the foreground color is the key to consider for the interference color pigment.

The relationship between interference color and pigment thickness:

Among them, the particle size of pearlescent pigments also has a great influence on the pearlescent effect produced. The smaller the particle size, the lower the gloss and the better the hiding power. The specific effects are as follows:

Particle size 2～10μm, low gloss, very strong hiding power,

Particle size 3 ~ 15μm, silky luster, strong hiding power,

Particle size 5-25μm, pearl luster, medium hiding power,

Particle size 9-45μm, soft luster, weak hiding power,

The particle size is 20-95μm, with shiny luster and very weak hiding power.

The particle size is 95-730μm, with shining luster, transparent and no hiding power.

What the interference color pearlescent pigment of the present invention adopts is titanium hydrochloride mica, and the mica particle of following physical parameter is obtained by grinding, grading, reacting, washing, calcining, screening:

Refractive index: TiO ₂ : 2.52, mica: 1.58;

Specific gravity: TiO ₂ : 3.9, mica: 2.8;

Particle size (μm): 20;

Thickness (μm): TiO ₂ : 0.06～0.17, Mica: 0.285;

The present invention adopts a light-sensitive interfering pearlescent pigment raw material, which does not show obvious color when added to the product. When it is applied on the skin, it will show different colors due to the change of light, and the displayed color can be adjusted according to the added interference. The raw materials of permanent pearlescent pigments vary.

A light-sensitive, whitening, brightening and colorful cream as described above is characterized in that the preservative component includes the following components by weight percentage:

A method for preparing the above-mentioned light-sensitive whitening, skin brightening and colorful cream is characterized in that it comprises the following steps:
