Description

Technical Field

[0001] The invention belongs to the technical field of makeup setting products, and particularly relates to a makeup setting spray and a preparation method thereof. Background Art

[0002] There are many types of makeup setting products, including loose powder, pressed powder, spray, etc. Due to the risk of inhalation and the portability of use, the proportion of sprays is increasing.

[0003] Setting spray is a setting product that sets makeup in the form of water mist. The sprayed water mist is light and the particles are small, which will not damage the makeup. The main ingredients of setting spray are water, moisturizer and film former. Water helps to blend the facial makeup and the ingredients of setting spray well, making the base makeup transparent and shiny; moisturizer can increase the moisture of the skin, prevent skin dryness, and make the makeup more docile; film former can form a thin film on the skin surface to increase the durability of the base makeup. However, most common setting spray products on the market are non-viscous water texture. After applying makeup, the film former evaporates to form a film. Due to poor moisturizing performance, the film is not durable, which in turn affects the makeup effect. In addition, the non-viscous water texture easily causes the raw materials to flocculate and precipitate, or when foreign matter enters during use, the foreign matter will quickly condense and aggravate the precipitation, resulting in poor atomization effect. Frequent shaking is required before use, which affects consumers' product experience. Summary of the invention

[0004] The invention aims to provide a makeup setting spray with good moisturizing performance and good makeup lasting effect.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0073] Performance Test:

[0074] The moisture content of the stratum corneum of the skin was tested for the setting sprays of the embodiments and comparative examples respectively according to the forearm test area capacitance method in the "QB / T 4256-2011 Guidelines for Evaluation of Moisturizing Efficacy of Cosmetics". The number of effective test volunteers was 30. Under the conditions of ambient temperature of 20°C to 22°C and relative humidity of 45% to 55%, the moisture content of the stratum corneum of the skin was tested before and 2 hours after the setting spray was used. The testing instrument was a stratum corneum moisture tester (CK MPA580-Corneometer), and the test dosage was (2.0±0.1) / cm per press. 2 The unit of the test value is Corneometer Unit (CU). The change in moisture content of the stratum corneum of the skin is calculated (the moisture content of the stratum corneum of the skin (average value) after using the setting spray for 2 hours minus the change in moisture content of the stratum corneum of the skin (average value) before using the setting spray). The results are shown in Table 2. The setting spray of Comparative Example 2 turned white and unstable due to the reaction of polyester-5, gellan gum and magnesium sulfate, and could not be put on the market as a qualified product, so no performance test was conducted.

[0075] Table 2

[0076]

[0077] Table 2 shows that compared with the setting spray of the comparative example, the setting spray of Example 1 and Comparative Example 6 has the most obvious effect on increasing the moisture content of the stratum corneum of the skin, indicating that the moisturizing effect of the setting spray of Example 1 and Comparative Example 6 is significantly improved.

[0078] Referring to the test method for the effect of cosmetics on transepidermal water loss in T / ZHCA003 2018, the moisture content of the stratum corneum of the skin was tested on the setting sprays of the embodiments and the comparative examples. The test personnel and the stratum corneum moisture content test were the same group of test volunteers. Under the conditions of ambient temperature of 20°C to 22°C and relative humidity of 45% to 55%, the transepidermal water loss rate after using the setting spray for 2 hours was tested. The test instrument was a transepidermal water loss rate meter (CK MPA580-Tewameter TMHex), and the test dosage was (2.0±0.1) / cm 2 , the test value unit is g / (m 2 h), and the change in transepidermal water loss rate was calculated (the transepidermal water loss rate (average value) after using the setting spray for 2 hours minus the change in transepidermal water loss rate (average value) before using the setting spray). The test results are summarized in Table 3. As above, Comparative Example 2 was not able to be marketed as a qualified product due to instability, and no performance test was performed.

[0079] Table 3

[0080] Example 1 Comparative Example 1 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Transepidermal water loss rate -2.81 -0.78 -1.79 -1.52 0.75 -2.24

[0081] The units in Table 3 are g / (m 2 h).

[0082] Table 3 shows that gellan gum can reduce the transepidermal water loss rate, and the effect is better at a certain dosage. Among them, the transepidermal water loss rate of Example 1 is the smallest, indicating that the skin barrier function of the makeup setting spray of Example 1 is the best.

[0083] The user sensory evaluation of the setting spray of the embodiment and the comparative example was carried out with reference to the General Rules for Sensory Evaluation of Cosmetics (T / GDCA003-2020), and the preference test method of volunteers in the hand control area in ISO 11136 was adopted to collect the test volunteers' preference data for the setting spray through questionnaires and scoring. The test volunteers were 35 healthy adult men and women without skin diseases (16 males, average age: 30.8 years old, 19 females, average age: 36.4 years old). The setting sprays of the embodiments and comparative examples were filled into spray bottles (the water output of the nozzle when pressed once was about 0.12 g), the same liquid foundation was applied to the faces of the test volunteers, the nozzle was pressed continuously for 5 times at a distance of 30 cm from the face (avoiding the lips and eyes), and the face was evenly sprayed in a circular manner, and the skin was left to dry naturally. After using the product for 8 hours, the feeling of use, the durability of the setting makeup, and the absorbency were scored respectively, and the overall preference was scored at the same time. The products were ranked in order of preference according to the overall preference scores, and a user evaluation opinion table for the setting spray product was summarized, as shown in Table 4.

[0084] Table 4

[0085]

[0086] The scoring standard adopts a 7-point system, with higher scores representing higher favorability, 1 being the worst and 7 being the best. Table 4 shows the average values.

[0087] In summary, the makeup setting spray of Example 1 takes into account both long-lasting moisturizing and long-lasting makeup holding, and is ranked first in user preference. It is a makeup setting spray product with a very good consumer product experience.
