[0058] Further, based on weight percentage, the cosmetic material composition includes: 3 to 10% of water.

[0059] That is, the content of water in the cosmetic material composition is 3 to 10% relative to the total weight. By setting the water content in the cosmetic material composition at 3 to 10%, it is possible to ensure the formation of a transparent and stable water-in-oil type preparation. When the water content in the cosmetic material composition is less than 3%, the content of pure water is insufficient to disperse the polymer; and when the water content in the cosmetic material composition exceeds 10%, due to phase inversion, it is not suitable for forming a transparent and stable water-in-oil type preparation.

[0060] The cosmetic material composition is a liquid preparation without viscosity and is designed to be a composition that is easy to mix and emulsify with water or other aqueous preparations. Therefore, a preparation that gels and results in reduced fluidity is not suitable for the cosmetic material composition.

[0061] Some embodiments of the present application provide a cosmetic material, including the cosmetic material composition in any of the foregoing embodiments; and

[0062] Water, aqueous extracts, or liquid aqueous cosmetic materials.

[0063] By adding the foregoing cosmetic material composition, the cosmetic material can form a viscous emulsion-like emulsified liquid preparation.

[0064] Further, the preparation of the cosmetic material includes any one of emulsions, essences, or creams.

[0065] The features and properties of the present application are further described in detail below in conjunction with examples:

[0066] Examples 1 to 7 and Comparative Examples 1 to 7

[0067] Cosmetic material compositions of Examples 1 to 7 and Comparative Examples 1 to 7 were respectively prepared according to the compositions recorded in Table 1 below and the following preparation method (the unit of the component content in Table 1: weight %).

[0068] Table 1

[0069]

[0070] Preparation method:

[0071] 1) Homogeneously disperse the raw materials corresponding to serial numbers 1 to 6 in each example or comparative example in Table 1 to prepare a polymer gel.

[0072] 2) Mix the raw materials corresponding to serial numbers 7 - 13 in each of the examples or comparative examples in Table 1 using an emulsifying device, and set aside.

[0073] 3) Add the polymer gel obtained in step 1) to the mixture obtained in step 2) and mix evenly to prepare each cosmetic material composition.

[0074] Test Example 1 Observation of the Appearance of the Cosmetic Material Composition

[0075] Observe the appearance of the cosmetic material compositions of Examples 1 - 7 and Comparative Examples 1 - 7 within 2 hours after preparation. The results are shown in Table 2.

[0076] Table 2

[0077]

[0078] As can be seen from the results in Table 1, the cosmetic material compositions prepared in Examples 1 - 7 of this application are all transparent liquid; while those in Comparative Examples 1 - 7 are semi - transparent or gel - like.

[0079] Among them, photos of the cosmetic material compositions prepared in Example 1 and Comparative Example 4 are shown in the Figure 1 specification appendix. Figure 1 Among them, the left sample is the cosmetic material composition prepared in Example 1; the right sample is the cosmetic material composition prepared in Comparative Example 4.

[0080] From Figure 1 the photos, it can also be clearly seen that the cosmetic material composition prepared in Example 1 is transparent liquid; while the cosmetic material composition prepared in Comparative Example 4 is semi - transparent liquid.

[0081] Test Example 2 Evaluation of the Formulation Stability of the Cosmetic Material Composition

[0082] According to the results of Test Example 1, except for Comparative Examples 2, 3, and 6 with a gel form after preparation, the formulation stabilities of the cosmetic material compositions of the remaining Examples 1 - 7 and Comparative Examples 1, 4, 5, 7 were evaluated.

[0083] Specifically, the cosmetic material compositions of Examples 1 - 7 and Comparative Examples 1, 4, 5, 7 were stored in a constant - temperature incubator at 25°C, 45°C, 4°C, and - 20°C for 4 weeks, and the appearance of the compositions was observed. At this time, the compositions stored at - 20°C were thawed at room temperature every week, the stability was observed, and then they were put back into the constant - temperature incubator for storage. The results are shown in Table 3 below.

[0084] Table 3

[0085]

[0086] As shown in Table 3 above, the cosmetic material compositions prepared in Examples 1 and 2 of the present application exhibit excellent formulation stability; however, phase separation phenomena were observed in the cosmetic material compositions prepared in Comparative Examples 1, 4, and 5. Thus, it can be confirmed that the formulation stability is not ensured.

[0087] As shown in Table 3 above, the compositions prepared in Examples 1-7 of the present application exhibit excellent dosage form stability; on the contrary, phase separation phenomena were observed in the compositions prepared in Comparative Examples 1, 4, 5, and 7 that do not belong to the present invention. Therefore, it can be confirmed that the dosage form stability of the comparative examples is not ensured.

[0088] Among them, the attached Figure 2 shows photos of the state of Comparative Example 4 shortly after preparation and after phase separation. Figure 2 In the figure, the left sample is the cosmetic material composition of Comparative Example 4 shortly after preparation; the right sample is the cosmetic material composition of Comparative Example 4 after being stored for four weeks.

[0089] From Figure 2 it can also be seen that for the translucent liquid cosmetic material composition prepared in Comparative Example 4, obvious phase separation phenomena occurred after being stored for a period of time.

[0090] Test Example 3: Using the cosmetic material composition prepared in Example 1 above, an emulsion was prepared, and the performance of the emulsion was investigated.

[0091] The cosmetic material composition of the present application can be mixed with water, general aqueous extracts, and liquid aqueous cosmetic materials, etc. in an appropriate ratio to be formulated into emulsion preparations such as emulsions, essences, and creams. To confirm this, the composition of Example 1 was added to pure water and shaken and mixed. The mixing ratio of the composition of Example 1 to pure water was set to a weight ratio of 10:1. As a result, it was confirmed that an emulsion-like emulsion preparation with viscosity could be formed, and it is shown in Figure 3 in.

[0092] As Figure 3 can be seen, using the cosmetic material composition prepared in Example 1 of the present application, an emulsion was prepared, and an emulsion-like emulsion preparation with viscosity was formed.

[0093] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
