Performance test

The cleansing creams prepared in examples 1 to 20 and comparative examples 1 to 14 were used as test subjects, 340 qualified volunteers were selected as test subjects to participate in the test by screening questionnaires and preliminary screening of the original values of the volunteers, and were randomly divided into 34 groups of 10 persons each. The test persons randomly distributed the test samples, and the test persons in each group used the cleansing cream prepared in the same example or comparative example. When the test sample is used, a test person uses the test sample to clean the face twice every day at regular time, the cleaning time is 8 am and 8 pm, the using amount is 1g, and the test time is 4 weeks.

Before the test begins, use melanin skin test appearance to detect the facial melanin content of the person of experimenting, after the test, use melanin skin test appearance to test the facial melanin content of the person of experimenting again, calculate the melanin surplus rate, the calculation method is:

melanin residual rate (melanin content after use/melanin content before use) × 100%, and the results of the same group calculation were averaged.

And after the test is finished, performing questionnaire survey and revisiting, investigating whether allergic symptoms appear after the cleansing cream is used, and counting the number of people with the allergic symptoms.

The test results are shown in Table 2 below.

As can be seen from the test data in table 2: the subjects who used the cleansing creams having pearl effect prepared in examples 1 to 20 all had a melanin residual ratio of less than 85% after use, which shows that the cleansing creams prepared in the examples of the present application have a good whitening effect after being used for cleansing, and of these, example 3 and example 4 are preferred examples.

By combining the example 1 and the comparative example 1 and combining the table 2, it can be seen that the residual melanin rate of the facial cleansing cream prepared in the example 1 after use is 83.6%, while the residual melanin rate of the facial cleansing cream prepared in the comparative example 1 after use reaches 94.5%, which indicates that the potassium hydroxide is alkaline by adding the potassium hydroxide into the raw materials, the alkalinity of the potassium hydroxide is neutralized by the acid in the facial cleansing cream, the facial cleansing cream can maintain a weakly acidic environment, and the mixture of the stearic acid, the myristic acid, the lauric acid and the potassium hydroxide is favorable for forming a bright pearlescent effect with ethylene glycol distearate in a specific ratio after being mixed with the stearic acid, the myristic acid, the lauric acid and the potassium hydroxide, so that a good whitening effect is achieved.

Combining the example 1 and the comparative example 2, and combining the table 2, it can be seen that, since the ethylene glycol distearate is added to the mixture after the stearic acid, the myristic acid, the lauric acid and the potassium hydroxide are mixed with each other, the ethylene glycol distearate is heated and emulsified under the synergistic action, so that the bright pearlescence effect is good, the generated pearlescence is finer and finer, the whitening effect is achieved, and meanwhile, the moisturizing effect is achieved while the skin is cleaned.

By combining examples 1, 3 and 4 and comparative examples 3 and 4 and combining table 2, it can be seen that the addition of stearic acid and potassium hydroxide in the raw materials has a better whitening effect on the facial cleanser, and is beneficial to having a good pearling effect.

As can be seen by combining examples 1, 13 and 14 and comparative examples 9 and 10, and table 2, the amount of the compound of oxitenmin having a skin conditioning effect added to the cleansing cream was 1: (0.6-0.8): (0.7-0.9): (0.7-0.9), the cleansing cream prepared in the range has good bactericidal effect, so that the pearlizing agent with pearly luster effect can play a greater role, the effect is maximized, and the number of people with allergic symptoms is relatively reduced.

In combination with examples 1, 15 and 16 and comparative examples 11 and 12, and in combination with table 2, it can be seen that the biological carbohydrate gum with skin conditioning function added to the facial cleanser has the weight ratio of deionized water, biological carbohydrate gum-1 and phenoxyethanol in the components of 1: (0.8-1.2): (0.1-0.5), the facial cleansing cream prepared in the range has the antibacterial effect, can also have the function of conditioning the skin, and has a better whitening effect.

In combination with examples 1, 17, 18 and comparative examples 13, 14, and in combination with table 2, it can be seen that the surfactant secondary surfactant, which is added to the cleansing cream, has a weight ratio of deionized water to potassium cocoyl glycinate in the composition of 1: (0.4-0.6), the facial cleanser prepared in the range enables the surface activity of the ethylene glycol distearate to be better, so that the facial cleanser has a better whitening effect.
