Problems solved by technology

[0004] In the existing solid cosmetic matrix, powdered cosmetics are usually prepared into tablets under pressure by a tablet machine. Since the cosmetics are only formed by pressing, they will scatter during use and are not easy to apply to the skin. Adhered to the skin, uneven application will occur, affecting the effect of cosmetics

preparation example Construction

[0028] On the one hand, the embodiment of the present invention provides a kind of preparation method of solid cosmetic base, see figure 1 ,include:

[0029] Step 1) mixing the film-forming agent, the active ingredient and water to obtain a mixed solution;

[0030] Step 2) Pour the obtained mixed solution into a mold, and dry to remove moisture to obtain an integrated solid cosmetic base.

[0031] The embodiment of the present invention provides a method for preparing a solid cosmetic matrix. The method has a simple process, and obtains an integrated solid cosmetic base by drying and molding the mixed liquid of the film-forming agent, active ingredients and water, which can improve the toughness of the solid cosmetic base, and the obtained solid cosmetic base does not contain preservatives, It can improve the activity of the active ingredients in the solid cosmetic matrix, and it is not easy to loosen and fall off when used, and it can be dissolved into a cosmetic with certa...

Embodiment 1

[0058] The concrete preparation method of described embodiment 1 is as follows:

[0059] S1) Mixing the film-forming agent and the active ingredient with a mass ratio of 0.3:1 and water to obtain a mixed liquid; wherein, the viscosity of the mixed liquid is 150 mPa·s.

[0060] S2) Pour the obtained mixed solution into a mold, and freeze-dry to remove moisture to obtain a sheet-shaped solid cosmetic base.

[0061] Wherein, the freeze-drying is specifically:

[0062] Pre-freezing section: freeze the mold filled with the mixed solution at -10°C for 1.5 hours, so that the moisture in the mixed solution is frozen into ice;

[0063] Sublimation stage: under the vacuum degree of 8 Pa, the temperature is 10 ℃ for 5 hours, and the ice formed in the pre-freezing section is sublimated to remove the free water in the mixed solution;

[0064] Re-drying stage: under a vacuum degree of 5 Pa, the temperature is kept at 5° C. for 4 hours, and the bound moisture in the mixed liquid is removed...

Embodiment 2

[0067] The concrete preparation method of described embodiment 2 is as follows:

[0068] S1) Mixing the film-forming agent and the active ingredient with a mass ratio of 2:1 and water to obtain a mixed liquid; wherein, the viscosity of the mixed liquid is 250mPa·s.

[0069] S2) Pour the obtained mixed solution into a mold, and freeze-dry to remove moisture to obtain a sheet-shaped solid cosmetic base.

[0070] Wherein, the freeze-drying is specifically:

[0071] Pre-freezing section: freeze the mold filled with the mixed solution at -40°C for 2 hours, so that the moisture in the mixed solution is frozen into ice;

[0072] Sublimation stage: under the vacuum degree of 30Pa, the temperature is -10°C for 10h, and the ice formed in the pre-freezing section is sublimated to remove the free water in the mixed solution;

[0073] Re-drying stage: under the vacuum degree of 10 Pa, the temperature is kept at 10° C. for 10 h, and the bound water in the mixed liquid is removed.

Abstract

The invention relates to the technical field of cosmetics, in particular relates to a preparation method of a solid cosmetic matrix and the solid cosmetic matrix. The method is simple in process and capable of improving the flexibility of the solid cosmetic matrix, so that the solid cosmetic matrix is unlikely to loosen when in use and can be dissolved in water to obtain the cosmetic which has ductility and elasticity and is easy to attach on a body part and uniform to smear. The preparation method of the solid cosmetic matrix comprises the fowling steps: step (1) mixing a film forming agent, active ingredients and water to obtain a mixed solution; and step (2) pouring the obtained mixed solution into a mold, drying the mixed solution to remove moisture, and obtaining an integrated solid cosmetic matrix.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a preparation method of a solid cosmetic base and the solid cosmetic base. Background technique [0002] In recent years, with the aggravation of air pollution and the prolongation of people's daily exposure to electronic products, more and more women are paying more and more attention to skin health and maintenance. [0003] Among the existing cosmetics, most cosmetics exist in the form of liquid, and a few exist in the form of solid. Toxic and harmful substances such as preservatives are added to most cosmetics to prolong the storage time of cosmetics. [0004] In the existing solid cosmetic matrix, powder cosmetics are usually prepared into tablets under pressure by a tablet machine. Since the cosmetics are only formed by pressing, they will scatter during use and are not easy to apply to the skin. If it is attached to the skin, uneven application will occur, which will af...
