Contrast Example 1

[0082] The differences between Contrast example 1 and Example 1 are, this example does not comprise Polyglyceryl-2-Triisostearate and the weight percentage of Polyglyceryl-2-Diisostearate is 30%. Besides, the other components and preparation method of making are the same with Example 1, to get water-containing lipstick.

Contrast Example 2

[0083] The differences between Contrast example 2 and Example 1 are, this example does not comprise Polyglyceryl-2-Diisostearate and the weight percentage of Polyglyceryl-2-Triisostearate is 30%. Besides, the other components and preparation method of making are the same with Example 1, to get water-containing lipstick.

Contrast Example 3

[0084] The difference between Contrast example 3 and Example 1 is, this example does not comprise Polyglyceryl-2-Triisostearate and Polyglyceryl-2-Diisostearate. Besides, the other components and preparation method of making are the same with Example 1, to get water-containing lipstick.

Contrast Example 4

[0085] The difference between Contrast example 4 and Example 1 is, this example does not comprise Carnauba Wax 15%. Besides, the other components and preparation method of making are the same with Example 1, to get water-containing lipstick.

Contrast Example 5

[0086] The differences between Contrast example 5 and Example 1 are, the preparation method in this example is: Mix all ingredients directly, stir and emulsify them, finally fill into the mould and get water-containing lipstick.

[0087] Functional test: Conducted stability tests (dropping point test: the higher the dropping point is, the better the stability is) and user sensory test (applied the lipsticks to 200 randomly selected females, had overall evaluation through moisturizing, comfort level and coloring; full score 100, lowest score 0, the higher the mark is, the better the lipstick is) with The water-containing lipsticks made in Example 1-3 and Contrast example 1-5. Test results are shown as Table 1 below.

TABLE-US-00001 TABLE 1 Sample Dropping point (° C.) Overall score Example 1 57 96 Example 2 59 90 Example 3 56 94 Contrast example 1 52 84 Contrast example 2 54 86 Contrast example 3 51 76 Contrast example 4 38 72 Contrast example 5 50 67

[0088] By the comparison between Example 1-3 and Contrast example 1-3, it can be seen the invention takes effect through adding Polyglyceryl-2-Triisostearate and Polyglyceryl-2-Diisostearate together, they coordinate with each other. It will lower the stability of lipstick and influence its taste if any one is missing. When both of them are missing, the taste and stability will drop significantly. By the comparison with Contrast example 4, it can be seen the missing of Carnauba Wax will sharply lower the dropping point, reduce stability and taste. By the comparison with Contrast example 5, it can be seen if directly mixing all ingredients together, the taste of lipstick will be bad that overall score is 67 only, and the stability is low.

[0089] Besides, the components of water-containing lipstick in the invention is complicated and mixed by reasonable percentage which provide the best effect. It has relatively high value in practical application, and it also provides a new idea in developing lipstick.

[0090] Applicant hereby declares that, the examples described in the invention are used to introduce The water-containing lipstick and its preparation method of making, but not limit to the above preparation method; it doesn't mean the invention must be made by said specific method. The people skilled in the art should be aware that, the following aspects should exist within the scope of protection and disclosure of the invention: any improvement, equivalent substitution of ingredient, addition of auxiliary component, selection of specific approach and etc.
