The present invention has the following advantages:
The following is a detailed description of the present invention in conjunction with specific examples. It should be noted that the following examples are only further descriptions of the present invention, but the scope of protection of the present invention is not limited to the following examples.
The present example relates to a concealer sunscreen facial cream, including the following weight percentages of each component:
The present example also relates to the aforementioned preparation method of the concealer sunscreen facial cream, including the following steps:
The method of comparison example 1 is basically the same as the method of example 1, except that Ve, aluminum octyl succinate and KF6038 are missing in the raw materials.
The method of comparison example 2 is basically the same as the method of example 1, except that KSP-300, KSP-100 and KP-545 are missing in the raw materials.
The method of comparison example 3 is basically the same as the method of example 1, except that Ve, KSP-100 and KP-545 are missing in the raw materials.
For 75 people with normal skin, 25 people in each group receive actual tests on the skin after use, and the results are shown in Table 1 below.
In the above table 1, the higher the value of each index, the better the effect, from the above table data, it can be see that all the data in example 1 of the present invention are far better than those in comparison example 1-3; which indicates that the present invention uses phenoxyethanol as a preservative, with the effect of effectively inhibiting microorganisms in the air, which is not only non-toxic and harmless, but also achieves the effect of preservative, which is more natural and harmless and applicable to more people; the product is not a simple combination, and the scientific ratio and reasonable preparation method make it more effective, in addition, its scientific preparation method is suitable for batch production with higher production efficiency.
