First, description of experimental results

According to the same process, successful water creams can be prepared in examples 1, 2, 3 and 5, and example 4 in the preparation process, the addition of the B phase oil phase to the neutralized A phase is that the body becomes suddenly thickened and the body skin feel becomes heavy, and the conversion is into a water-in-oil system, thus excluding the experimental results of example 4, and it can be seen that the phase inversion occurs when the content of potassium cetyl phosphate, i.e., emulsifier-1, is too high.

Second, effective examples physical and chemical Properties of the product

The stability tests of the water powder creams prepared in examples 1, 2, 3 and 5 were carried out according to the methods common in the cosmetics industry, and the results are shown in Table 2.

TABLE 2 summary of physicochemical Properties

As can be seen from Table 2, the gouache creams prepared by the method of the invention in the examples 1, 2, 3 and 5 have good heat resistance, cold resistance and stability of cycle test.

Third, product efficacy assessment

A commercially available water powder cream was used as a comparative example.

1. The test substance: example 1, example 2, example 3, example 5 and comparative example (commercial water cream) were subjected to QB/T4256-2011 "guideline for evaluating moisturizing efficacy of cosmetic preparations" as a reference standard.

2. Subject: the subjects were 50 women in good health, with the ages ranging from 20 to 40 years, and were not treated with a similar functional cosmetic within 2 days prior to testing. The subjects were randomized into 5 groups of 10 individuals each, and each tested for example 1, example 2, example 3, example 5, and comparative example, the test sites were facial and required uniform application. The test instrument is as follows: skin moisture content tester Corneometer CM825 (CK, Germany) and moisture loss tester Tewameter TM 300 (CK, Germany).

3. The test flow comprises the following steps:

1) testing environment requirements: constant temperature and humidity (temperature 22 + -2 deg.C, relative humidity 50% + -5% RH) environment, subject was asked to sit still for 30min before testing data.

2) The test method comprises the following steps: the skin surface water loss was tested using a Tewameter TM 300, with an average taken 3 times per test area; after the skin surface moisture loss test was completed, the skin moisture content was measured using Corneometer CM825 and 5 averages were taken for each test zone.

3) Sample smearing: the test sample was applied to the test area of the subject's skin in an amount of 2mg/cm 2.

4) Data acquisition: the data acquisition time was 0 hours (i.e., the first pre-sample application skin test), 2 hours, 4 hours, 2 weeks, 4 weeks of the first sample application; during which the subject applies an equal amount of the test sample to the test area each morning and does not apply any other cosmetic to the test area; data at weeks 2 and 4 were determined at 4 hours after sample application on the day.

4. Test results

1) MMV value of skin moisture content

a. The MMV value of the skin moisture content is larger, the moisture content is larger, and conversely, the moisture content is smaller.

b. The higher the hydration rate, i.e., the skin hydration rate, the more pronounced the moisturizing effect, the hydration rate being (test skin hydration-control skin hydration)/control skin hydration × 100%.

c. The test skin hydration level is the data collected after the subject applied the sample, and the control skin hydration level is the data collected before the subject first smears the sample.

Referring to fig. 1, the data set was analyzed for normal distribution using the skin hydration rate before and after the test sample using SPSS 22.0 software, and the statistical results were all in accordance with normal distribution. The MMV values of moisture content in the test area of the samples were significantly different at 2 hours, 4 hours, 2 weeks and 4 weeks from the paired t test results before use (P < 0.05).

It can be seen that the MMV values for skin moisture content in the test area are higher after the test sample is applied by the subject over the test period than before the application. By comparing the hydration rate data at the 2 nd hour and the hydration rate data at the 4 th hour, the water-blooming short-time water replenishing effects of the water-blooming in the examples 2, 3 and 5 are better; comparing the hydration data at week 2 and week 4, it can be seen that the skin moisturizing effect of the products of example 2, example 3, and example 5 is significantly better and the skin moisturizing ability of the skin itself is improved, compared to the comparative example, with the most significant effect of example 3.

2) TEWL value of transdermal water dispersion

a. The smaller the value of the percutaneous water loss TEWL value is, the less the water loss is, and the stronger the water locking capacity is; on the contrary, the weaker the water locking capacity is;

b. the water loss rate and the change rate of the TEWL value, the lower the value, the better the water locking effect.

Referring to the attached figure 2, the statistical results of the TEWL values of the front and back transdermal water dispersion loss of the test sample are used, the SPSS 22.0 software is used for carrying out normal distribution analysis on the data group, and the statistical results are all in accordance with normal distribution. The sample test area transdermal water dispersion loss TEWL values were very significantly different (P < 0.01) from the paired t-test results before use at hours 2, 4, weeks 2 and 4.

It is seen that the transdermal water dispersion loss in the test area is lower after the test sample is applied to the test subject than before the application during the test period. Comparing the data of the skin water loss rate at the 2 nd hour and the 4 th hour, the skin water loss reducing effects of the embodiment 2, the embodiment 3 and the embodiment 5 are better; comparing the data of the skin water loss rate at week 2 and week 4, it can be seen that the effects of reducing the transdermal water loss are significantly better and the skin moisture retention is improved by the products of example 2, example 3 and example 5, the most significant of which is example 3, compared to the comparative example.

By combining the analysis results, the products of the examples 2, 3 and 5 can obviously improve the moisture content of the skin and reduce the transdermal moisture loss, which indicates that the test sample has obvious moisturizing effect, and the moisturizing effect is better than the instant effect in the weeks 2 and 4 of use, and indicates that the moisturizing capability of the skin can be effectively improved after long-term use. In example 1, the skin feel is light and thin, and the light grease is completely used, and the moisturizing capability of the light grease is slightly inferior to that of the comparative example.

Fourth, sensory analysis and evaluation

1. The test substance: example 1, example 2, example 3, example 5 and comparative example.

2. Subject: the total 50 people, female 10 people, age 18-40 years, meet the volunteer selection criteria of the subject.

3. The evaluation method comprises the following steps: applying 80ul of sample on the back of hand, coating the sample on the back of hand by using another sample in a soft and rotary manner for 10 times, and then sequentially evaluating the moistening feel, the spreadability, the smoothness, the skin-sticking property and the comfortable feeling after use of the sample in a mode of scoring and averaging (the higher the score is, the better the lasting feel, the moistening feel, the spreadability, the smoothness, the skin-sticking property and the comfortable feeling after use of the product are) to obtain the better the moistening feel, the spreadability, the smoothness, the skin-sticking property and the comfortable feeling after use of the sample.

The results obtained by sensory evaluation are shown in Table 3 below

TABLE 3 sensory evaluation score statistics sheet

And (4) evaluation results: the results of the statistics of the composite subject scores after application are shown in Table 3. As can be seen from the evaluation results, the water creams of examples 2, 3 and 5 of the present invention are superior to the comparative water cream in durability, feeling of moisturization, spreadability, smoothness, skin-fitting property and after-use comfort. The moisturizing effect of example 1 was the lowest, and was slightly lower than the comparative example, but the spreadability and smoothness were indeed the best, mainly the light, thin grease of example 1. Compared with the example 5, the makeup holding effect of the example 2 is obviously higher than that of the example 5, mainly because the content of the emulsifier-1 in the example 5 is higher than that of the emulsifier-1 in the example 2, and the emulsifier-1 is an oil-in-water emulsifier, can emulsify grease and is easy to fall off when meeting water. The addition amount is too high, which can affect the make-up effect of the product. Wherein example 3 is superior to all of the regimen creams in terms of durability, moisturization, spreadability, smoothness, skin-hold, and after-use comfort.

The water-in-oil water-based cream has the advantages of good makeup holding effect, skin color correction, other skin care effects, safety, mildness, good use experience, and capability of ensuring the stability of the product and having good makeup holding effect and moisturizing capability by using the powder subjected to surface treatment by using the isopropyl titanium triisostearate and reasonably matching the addition amounts of the emulsifier-1 and the emulsifier-2.
