Performance testing

1. Physical Property test

The properties of the lipsticks of examples 1-8 were tested according to GB/T26512-2001 lip gloss and technical Specification for cosmetic safety, and the test results are shown in Table 2.

TABLE 2 test table for the properties of lipsticks in examples 1-8

According to the data in the table 2, the color-changing lipstick prepared by the invention meets the requirements of sensory indexes, physical and chemical indexes and sanitary indexes in GB/T26512-2001 lip balm.

2. Stability test

The lipsticks of examples 1 to 8 were used as samples, and stability tests were carried out in the following manner, and the test results are shown in Table 3.

The lipsticks prepared in each example and comparative example were divided into three sets of tests, which were applied to the lips of the volunteers before the tests, and after 1min, photographs of the color of the lips of the volunteers were taken; then placing different groups of lipstick samples in normal temperature, high temperature and low temperature environments for storage respectively, smearing the lipstick test on the lips of the same volunteer again after a certain time, and taking a picture of the color of the lips of the volunteer after 1 min; comparing the same lipstick sample group before and after the test, and taking photos of the color of the lips of the volunteers; during the two tests, the lip temperature of the volunteers is kept consistent as much as possible; the force for smearing the lipstick twice is kept consistent as much as possible. A portable color difference meter with the model number of NR60CP, which is produced by Guangzhou Shanghruiming instruments Limited, is adopted to carry out color comparison on two photos before and after the test. Since the color difference meter represents the color by the numerical values of L, a and b, in the test, the color of the colorant is only faded, so the hue L before and after the colorant test is set to be unchanged, the ambient brightness b when shooting before and after the test is also set to be unchanged, the difference between before and after the test can be measured by only testing the value of the saturation a, the numerical value of the saturation a is changed within 0-100, the color is too light to be included in the test range when the saturation a is 0-50, therefore, the color with the saturation a of 50-100 is made into the color card of the test under the condition that the L and the b are kept as fixed values, and the numerical value of a is 10 for each change, 100-90 for 1 grade, 90-80 for 2 grades, 80-70 for 3 grades, 70-60 for 4 grades, 60-50 for 5 grades, the a values of two photos are tested by the color difference meter, and recording according to the grade corresponding to the color card of the test.

(1) And (3) normal temperature stability: the lipstick was taken out after the sample was left to stand at (20. + -. 2) ° C under a relative humidity of (65. + -. 5)% for 6 months.

(2) High-temperature stability: placing the sample at 45 + -1 deg.C under relative humidity of 65 + -5% for 3 months, taking out lipstick, and standing under relative humidity of 65 + -5% at 20 + -2 deg.C for 24 h.

(3) Low-temperature stability: placing the sample in an environment with a relative humidity of (65 +/-5)% at (-5 to-10) ° C for 3 months, taking out the lipstick, and adjusting and placing for 24 hours in an environment with a relative humidity of (65 +/-5)% at (-5 to-10) ° C.

TABLE 3 lipstick stability test Table for examples 1-8 and comparative example 3

As is clear from the data in Table 3, the colors of the colorants prepared in preparation example 1 of the purple vegetable colorant and preparation example 1 of the red vegetable colorant of the present invention did not change significantly after storage at normal, high and low temperatures, indicating that the colors of the lipsticks of examples 1-3 of the present invention can still have excellent color stability in a complicated environment.

The purple vegetable colorant of the lipstick of example 4 is prepared from preparation 2 of purple vegetable colorant, and the red vegetable colorant is prepared from preparation 2 of red vegetable colorant; compared with example 1, the color of the lipstick changed 2-3 grades after the stability test, which shows that the lipstick has poor stability in the lipstick, especially when the environment is changed, the color of the lipstick is obviously changed when the sweet potato root extract and the radish root extract are directly added into the lipstick as the colorant.

The colorants of examples 5-6 were all selected from commercially available products, and compared to example 1, the color of the lipstick changed by 1-2 grades after the stability test, indicating that the colorants prepared according to the present invention have better color stability than the conventional commercially available products.

The plant-extracted emollient of comparative example 3 was prepared from preparation example 3 in which the plant-extracted emollient was selected, and the plant-extracted emollient was not added in comparative example 3, and compared to example 1, the color of lipstick was changed by 0-1 grade after stability test, indicating that the addition of the plant-extracted emollient of the present invention can improve the color stability of colorant.

3. Sensory scoring

110 volunteers of 20 to 40 years old were randomly selected and divided into 11 groups of 10 persons, and after makeup removal of lips, the lipsticks of examples 1 to 8 and comparative examples 1 to 3 were applied and scored from the moist feeling, greasy feeling, color, fine smoothness and moisture retention of the lipsticks, respectively, with a score of 0 to 10, and the highest score of 10, and the average score of each group was taken, and the test results are shown in Table 4.

TABLE 4 sensory evaluation of lipstick for examples 1-8 and comparative examples 1-3

According to the data in Table 4, the lipsticks prepared in examples 1-3 of the present invention have excellent moisturizing effect, sliminess, and persistence of moisture retention, are not greasy, and have a fresh and natural color, compared to the lipsticks of conventional comparative examples 1-2.

The purple vegetable colorant of the lipstick of example 4 is prepared from preparation 2 of purple vegetable colorant, and the red vegetable colorant is prepared from preparation 2 of red vegetable colorant; the color and the sliminess score of the lipstick were decreased compared to example 1, indicating that the direct addition of the sweet potato root extract and the radish root extract to the lipstick as the colorant can make the lipstick take on a natural color, but the dispersibility thereof in the lipstick is poor and the sliminess of the raw material is also affected.

The colorants of examples 5-6 were selected from commercially available products and the lipstick scores did not change significantly, indicating that the use of commercially available colorants in the lipsticks of the present invention still provided good moisturized, slimy, long lasting moisturization, non-greasy, and better color.

The plant-extracted emollients of examples 7 and 8 were selected from the group consisting of the preparation examples 2 and 3 of the plant-extracted emollients, and the moisturizing sensation, the smoothness and the moisturizing durability of the lipsticks of examples 7 and 8 were reduced compared to those of example 1, which shows that the addition of the plant-extracted emollient prepared in preparation example 1 of the plant-extracted emollient of the present invention can significantly improve the moisturizing sensation, the smoothness and the moisturizing durability of the lipsticks.

The fact that the moisturizing feel, the smoothness and the moisturizing duration of the lipstick of the comparative example 3 are obviously reduced and the color score is also reduced compared with the lipstick of the example 1 without adding the plant extract emollient in the comparative example 3 shows that the addition of the plant extract emollient can improve not only the use feel of the lipstick, but also the dispersibility of the plant colorant of the invention, thereby improving the color of the lipstick.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
