Description

TECHNICAL FIELD

[0001] The present application relates to the field of cosmetics, in particular, to a moisturizing composition, a mask liquid and a preparation method thereof. BACKGROUND

[0002] In the field of cosmetics, as a high-efficiency skin care carrier, the moisturizing and brightening effects of mask liquid have become the core demand of the market, and consumers are increasingly demanding products that are mild and non-irritating and have dual effects. Currently, mask liquid moisturizing technology focuses on single functional ingredient compounding or optimization of moisturizing efficiency, and existing brightening technology has obvious limitations: one type relies on strong functional ingredients such as niacinamide and tranexamic acid to inhibit melanin production or transmission to achieve brightening, but such ingredients have the risk of irritation to sensitive skin; another type uses physical sunscreens such as mica and titanium dioxide, which can easily block pores and affect skin metabolism; some products indirectly improve sallow skin tone through conventional moisturizing ingredients, but the effect is weak and passive, and lacks targeted design. At the same time, there is no related scheme for compounding specific moisturizing compositions to produce unexpected brightening synergies, and most moisturizing compositions such as sphaerotrichum, seaweed extract, and polymer network are only focused on single functions such as water locking and repair. Therefore, developing a technical solution that achieves unexpected brightening effects through the synergistic effect of specific moisturizing compositions has become a technical problem that needs to be solved in this field.

[0003] Chinese invention patent CN114767550B discloses a composite moisturizing mask liquid, which uses betaine and rhamnose as a combined moisturizing agent to achieve synergistic moisturizing with different molecular weight hyaluronic acid, which can reduce the amount of moisturizing agent and improve the long-term moisturizing effect, but does not involve any brightening function and is limited to basic moisturizing dimension.

[0039] Performance testing methods and data The facial mask liquids prepared in the examples and comparative examples were tested for skin moisture content, gloss, and ITA. The specific methods are as follows: 1. Collection of basic skin parameters Subjects reporting dull and lackluster facial skin were recruited, and the experiment was explained to them. First, the facial skin was cleansed using a laboratory-provided cleanser, and the test area was dried with a lint-free tissue. The test area was then left exposed and stabilized in a temperature- and humidity-controlled laboratory (20-22℃, 40%-60% relative humidity) for 20 minutes. Initial skin parameters D0 were collected from the test area, namely the initial values ​​of MAP580 glossiness, ITA brightness, and initial skin moisture content.

[0040] 2. Sample testing and skin parameter collection The mask sample (half a sheet / 15g of mask liquid) was randomly applied to the left and right sides of the subject's face according to the random number in the random table. After 15 minutes, the mask was removed, and any residual mask liquid was washed off with water. The immediate skin parameters D of the test area were collected. 15 This refers to the real-time values ​​of MAP580 glossiness, whiteness ITA value, and skin moisture content.

[0041] 3. The growth rate (G%) is calculated using the following formula:

[0042] The parameter growth rate data for the examples and comparative examples are shown in Table 3 below.

[0043] Table 3

[0044] Data Analysis and Conclusions (All percentages below are quality percentages): 1. As can be seen from Examples 1-5, in the specified mask system, when the first moisturizing component and the second moisturizing component are used in combination, and the amount of the first moisturizing component is 0.25-1.0% and the amount of the second moisturizing component is 1.5-4.0%, each example shows a relatively excellent and stable effect in terms of the growth rate of skin moisture content, the growth rate of luster and the growth rate of ITA value.

[0045] 2. In Comparative Example 2, only 0.50% of the first moisturizing component was added, without adding the second moisturizing component; in Comparative Example 3, the first moisturizing component was not added, but only 2.0% of the second moisturizing component was added. A comparison with the test data of Examples 1-5 shows that the effect of using the first or second moisturizing component alone in the mask system is significantly different from the effect of using them together.

[0046] 3. In Comparative Example 2, only 0.50% of the first moisturizing component was added, without adding the second moisturizing component; in Comparative Example 3, the first moisturizing component was not added, but only 2.0% of the second moisturizing component was added; while in Example 4, both 0.50% of the first moisturizing component and 2.0% of the second moisturizing component were added. The increase in skin moisture content in Example 4 was significantly higher than in Comparative Examples 1 and 2, indicating a synergistic effect between the first and second moisturizing components in moisturizing. Similarly, the increase in ITA value in Example 4 was much higher than in Comparative Examples 1 and 2, indicating a synergistic effect between the first and second moisturizing components in improving skin brightness. Furthermore, the increase in glossiness in Example 4 was also significantly higher than in Comparative Examples 1 and 2, indicating a synergistic effect between the first and second moisturizing components in improving skin glossiness.

[0047] 4. In Examples 1 and 2, the amount of the first moisturizing component remained constant. With the increase of the second moisturizing component, the growth rates of skin moisture content, gloss, and ITA value all increased. In Examples 4 and 5, the amount of the second moisturizing component remained constant. With the increase of the first moisturizing component, the growth rates of skin moisture content and ITA value increased, but the growth rate of gloss decreased. This illustrates the complexity of the interaction between the first and second moisturizing components, and that there is an optimal ratio range for their combined use.

[0048] 5. In Example 3, 0.5% of the first moisturizing component and 3.0% of the second moisturizing component were added; in Example 1, 1.0% of the first moisturizing component and 4.0% of the second moisturizing component were added. Although the amount of the first moisturizing component and component B added in Example 3 was lower than in Example 4, it still exhibited a better increase in gloss and ITA value. This again illustrates the complexity of the interaction between the first and second moisturizing components, and that there is an optimal ratio for their combined use.

[0049] 6. In Comparative Example 4, a similar moisturizing component M was used to replace the first moisturizing component at an addition level of 0.5%, while the second moisturizing component was added at an addition level of 2.0%. In Comparative Example 5, the first moisturizing component was added at an addition level of 0.5%, and a common moisturizing component N was used to replace the second moisturizing component at an addition level of 2.0%. In Comparative Examples 4 and 5, only the increase in skin moisture content showed good performance, while the increases in radiance and ITA value were poor. This indicates that the synergistic effect between the first and second moisturizing components is highly specific; replacing either component immediately weakens or eliminates the brightening effect.

[0050] In summary, the combination of the first and second moisturizing components is not a simple functional additive, but rather produces a synergistic effect, providing an excellent new method for solving the technical problem of brightening face masks. Analysis of the current embodiments and comparative examples shows that the two components have excellent synergistic effects, with the best moisturizing and brightening effects achieved when the first moisturizing component is added at 0.5% and the second moisturizing component at 3.0%.
