Performance test

1. Usage sense test

Twenty women 20-30 years old are selected from volunteers, the products prepared in each example and comparative example are subjected to a use feeling test, and the coating smoothness and the halation are scored, wherein the score is 1-10 points, the higher the coating smoothness score is, the better the use feeling is, and the higher the halation score is, the more severe the halation is. The score averages are recorded in table 2.

TABLE 2

It can be seen from the combination of examples 1-4 and comparative example 4, and Table 2 that the formulation used in the present application can achieve good smoothness and feel in use as compared to the addition of talc, and can achieve substitution of talc.

It can be seen from the combination of examples 4 to 6 and Table 2 that the more the content of polymethylsilsesquioxane, the better the smoothness, and as a filler for talc, the polymethylsilsesquioxane has a remarkable effect of improving the smoothness of lipstick, but is too much liable to halation.

It can be seen from a combination of example 1, example 4 and example 7 and a combination of table 2 that the toner content has some influence on the smoothness of the lipstick, probably because of a certain filler effect.

As can be seen from the combination of examples 4 and examples 8-10 and Table 2, the porous starch particles obtained by the enzymolysis modification have better filling effect, the product has uniform texture and high smooth feeling, and the porous starch which is not modified by the butyric anhydride by the enzymolysis modification only has poor mixing effect with other substances, influences the overall uniformity and reduces the smooth feeling when used.

As can be seen from the combination of examples 4 and 11 and Table 2, paraffin wax and other raw materials were dissolved by heating, and the mixing effect was poor, and the overall use smoothness was impaired. This is because the melting point is higher after the paraffin is added, the subsequent grinding step is harder, and the grinding and mixing effects are poor.

It can be seen from the combination of examples 4 and 12 and Table 2 that by mixing uniformly by stirring, the particle dispersion effect is not better than that of ultrasonic dispersion, and thus the smoothness of the obtained product is also relatively poor.

It can be seen from the combination of example 4 and comparative examples 1-2, and Table 2 that compounding of the three wax components has a large influence on the overall smoothness, removal of microcrystalline wax has a large influence on the smoothness, and the use of the substitute polyethylene makes the product harder and has a large reduction in smoothness.

It can be seen that caprylic/capric-triglyceride has a good effect on improving the smoothness of the product by combining example 4 and comparative example 3 and by combining table 2.
