Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cosmetics, in particular to a preparation method of a quick and long-acting soothing and repairing composition suitable for sensitive skin and application thereof. BACKGROUND

[0002] Skin, as the largest organ of the human body, has functions of barrier protection, sensory conduction, body temperature regulation and aesthetic display. The skin barrier protects the body from external environmental hazards, helps maintain skin moisture, prevents excessive water loss, and thus maintains the softness and elasticity of the skin. However, irregular lifestyle phenomena such as staying up late, overeating, and excessive ultraviolet radiation, as well as excessive skin cleansing, can easily cause skin problems such as sensitive skin.

[0003] The soothing and repairing products on the current market generally have three limitations: traditional anti-sensitivity ingredients have a slow effect, which cannot meet the immediate soothing needs of sudden redness and pain of the skin; barrier repair ingredients mostly focus on physical moisturizing, lacking synergistic regulation of inflammatory pathways and photodamage; and some fast-acting anti-inflammatory products rely on hormones or strong ingredients, which may pose a risk of irritation and dependence.

[0004] Camellia chrysantha is a plant of the Theaceae family, and is known as the "Queen of Tea" and "Giant Panda of the Plant World" due to its unique golden yellow flowers. The flowers and leaves are rich in proanthocyanidins, flavonoid glycosides (such as quercetin glycoside and myricetin), tea polyphenols and various trace elements, which endow them with significant antioxidant, anti-inflammatory and moisturizing effects. However, the stability of Camellia chrysantha extract restricts its application breakthrough, and the honey produced by bees from the nectar of Camellia chrysantha flowers not only retains the inherent sugar moisturizing matrix and enzyme activity of honey, but also contains unique active ingredients of Camellia chrysantha, and has better stability than Camellia chrysantha extract, showing significant potential in skin care applications. Therefore, it is of great significance to study a soothing and repairing composition. SUMMARY

[0005] In view of the above defects or improvement needs of the prior art, the present application provides a preparation method of a quick and long-acting soothing and repairing composition suitable for sensitive skin and application thereof. The soothing and repairing composition forms a protective film on the skin surface, deeply moisturizes and locks in water, and blocks inflammatory pathways, thereby soothing redness and repairing the skin barrier, and the effect can be immediately realized and continuously maintained, which is suitable for sensitive skin and solves the problems of slow effect, single action pathway and strong irritation of existing soothing and repairing products.

[0054] Performance test

[0055] Test Example 1: Verification of soothing and repairing effect of the composition

[0056] This test example investigates the soothing and repairing effect of the compositions prepared in Examples 1-6 and Comparative Examples 1-12.

[0057] The cell line used is human keratinocyte HaCaT (BeNa Biotech), and the test conditions are: incubator temperature 37±1℃, humidity 90±5%, carbon dioxide 5±1%; the cells are cultured and treated according to the grouping, and then tested, and the specific test is the detection of inflammatory factors IL-6 and filaggrin FLG content, and the test method is as follows:

[0058] (1) The cell suspension was inoculated in a 96-well cell culture plate, with a density of 2000 cells per well, and 100 μL of DMEM medium (2105341, Gibco) was added to each well, and cultured for 24 h;

[0059] (2) Discard the supernatant, add 100 μL of PBS buffer to each well, and expose the cells to UVB irradiation for 10 minutes, with a dose of 100 mJ / cm 2 ;

[0060] (3) Discard the supernatant, add 100 μL of DMEM medium to the blank control group, and add 100 μL of DMEM medium containing 0.01% of the corresponding sample (compositions prepared in Examples 1-7 and Comparative Examples 1-12) to the test groups, and set 6 parallel repeats for each group;

[0061] (4) After 48 h of incubation, the culture solution and cells were collected, respectively;

[0062] (5) Inflammatory factor IL-6 content detection: the human IL-6 ELISA kit (EHC007.96, Shenzhen Xingboshen Biological Technology Co., Ltd.) was used to detect the content of the inflammatory factor IL-6 released by the cells in the culture solution.

[0063] (6) Filaggrin FLG content detection: the collected cells were lysed with RIPA cell lysis solution containing protease inhibitors, the lysed samples were centrifuged at 12000 g for 5 minutes, the supernatant was taken, and the human filaggrin (FLG) ELISA kit (item number BLL107115E, Bailile Biological) was used to detect the filaggrin FLG content of the supernatant of each group of tissues;

[0064] Inflammatory response can affect the stability of skin structure through pathways such as destroying skin barrier function, degrading collagen, and triggering pigmentation. Long-term or excessive inflammatory response can lead to decreased skin defense and accelerate the aging process. Interleukin-6 (IL-6) is a marker of inflammatory response, and its elevated level represents the presence of inflammatory response in the body.

[0065] Filaggrin (FLG) is an important molecule that connects keratin fibers in the stratum corneum of human skin. Under the assistance of FLG monomers, keratin fibers regularly aggregate to form a solid physical barrier in the outermost layer of the epidermis, playing a role in strengthening the skin.

[0066] The soothing ability of the composition is represented by the improvement of the inflammatory factor IL-6, and the skin barrier repair ability is represented by the improvement of the filaggrin FLG content. The IL-6 improvement rate and the FLG improvement rate are calculated according to the following formula:

[0067] IL-6 improvement rate = (1-IL-6 content 样品处理 / IL-6 content 空白对照 ) x 100%;

[0068] FLG improvement rate = (FLG content 样品处理 / FLG content 空白对照 -1) x 100%;

[0069] The data is presented as an average value. As can be seen from the data of Example 1 and Comparative Examples 3-12 in Table 2, the IL-6 improvement rate and the FLG improvement rate of the composition of Example 1, which is prepared by compounding the four components of tea honey, oat extract, myrobalan extract and schisandra extract, are significantly increased, indicating that the four components of tea honey, oat extract, myrobalan extract and schisandra extract have a synergistic effect, and the prepared composition has excellent soothing and repairing effect.

[0070] As can be seen from the data of Examples 1-6 and Comparative Examples 1-2, when the weight ratio of tea honey, oat extract, myrobalan extract and schisandra extract is (2-3):(0.1-0.2):(0.5-1):(0.1-0.2), the soothing and repairing effect of the composition is better.

[0081]

[0082] Application Example 7: Compared with Application Example 1, the difference is that the soothing repair composition is added into the emulsion at a concentration of 2 wt% in Application Example 7, and the preparation method is the same as that in Application Example 1.

[0083] Application Example 8: Compared with Application Example 1, the difference is that the soothing repair composition is added into the emulsion at a concentration of 6 wt% in Application Example 8, and the preparation method is the same as that in Application Example 1.

[0084] Comparative Application Example 13 (blank application example): Compared with Application Example 1, the difference is that the emulsion of Comparative Application Example 12 does not add the soothing repair composition, and an equal amount of deionized water is used instead of the composition, and the preparation method is the same as that in Application Example 1.

[0085] Test Example 2: Human skin patch test

[0086] Thirty volunteers, 15 males and 15 females, aged 20-50 years old, were recruited, and a closed patch test method was used. 0.025 mL of the test sample (emulsion prepared by Application Examples 1-8, Comparative Application Examples 1-12, and the blank application example) was placed in a specific patch tester, which was attached to the volunteer's arm with a low-sensitization tape, and was lightly pressed to evenly attach to the skin, and was left for 24 h; the blank control group was distilled water, and the blank application example was the emulsion without the soothing repair composition. After 24 h, the patch tester was removed, and the skin reaction was observed after 0.5 h, 24 h, and 48 h, and the results were recorded. The skin adverse reaction grade is shown in Table 4 below.

[0087] The results of the human skin patch test show that the Application Examples 1-8, Comparative Application Examples 1-12, and the blank application example of the present application have no skin adverse reactions after 0.5 h, 24 h, and 48 h of observation, and all are negative reactions, indicating that the emulsion prepared by the composition provided by the present application is safe, and it is safe and non-irritating to human skin.

[0090] Test Example 3: Human efficacy test

[0091] Experimental method: 126 Asian adult test subjects aged 18-60 years who self-identified as having sensitive skin were selected and randomly divided into 21 groups, with 6 people in each group. The volunteers applied 1 g of sample to the whole face once in the morning and once in the evening (the sample was the emulsion prepared according to application examples 1-8, comparative application example 1-12, and the blank application example) each day. Data were collected before use (T0), 30 min after use (T30 min), and at 7 days after use (T7). After the volunteers washed their faces with facial cleanser and sat in an air-conditioned room with a temperature of 21 ± 1 °C and a humidity of 50 ± 10% for 30 min, the researchers measured the skin moisture content of the cheekbones using a skin moisture test probe (Corneometer); photographed the faces of the volunteers using Visia-7, and performed image analysis on the red region images to obtain the a* value; and measured the trans-epidermal water loss (TEWL) value of the cheekbones using a skin moisture loss test probe (TewaMeter®TM Hex). At the first visit, the volunteers were first measured for the initial value before use, then applied the sample to the whole face, and after sitting for 30 min, the values after 30 min of sample use were measured.

[0092] The skin moisturizing ability was represented by the improvement in skin moisture content, the skin soothing ability was represented by the improvement in a* value, and the skin barrier repair ability was represented by the improvement in TEWL value, which were calculated according to the following formulas, respectively:

[0093] The skin moisture content improvement rate = [(sample Tx - sample T0 ) / sample T0 - (blank application example Tx - blank application example T0 ) / blank application example T0 ] x 100%;

[0094] The a* value improvement rate = [(sample T0 - sample Tx ) / sample T0 - (blank application example T0 - blank application example Tx ) / blank application example T0 ] x 100%;

[0095] The TEWL value improvement rate = [(sample T0 - sample Tx ) / sample T0 - (blank application example T0 - blank application example Tx ) / blank application example T0 ] x 100%;

[0096] In the formula, sample T0 is the data of each index before use (T0) of the sample group; sample TxThe data of each index of the sample group using 30 min (T30min) or using 7 days (T7) are used; blank application example T0 The data of each index of the blank application example before use (T0) are used; blank application example Tx The data of each index of the blank application example on the Xth day are used;

[0097] The calculation results are averaged, and Table 5 is specifically shown.

[0098] Table 5: Human efficacy test data of each group of emulsions

[0099]

[0100] As can be seen from the data of application example 1 and comparative application examples 3-12 in Table 5, the skin moisture content improvement rate, a* value improvement rate and TEWL value improvement rate of the emulsion of application example 1 using four components of honey of camellia japonica, oat extract, myrobalan extract and schisandra chinensis extract are all significantly increased, indicating that the four components of honey of camellia japonica, oat extract, myrobalan extract and schisandra chinensis extract have a synergistic effect, and the prepared emulsion has excellent soothing and repairing effect.

[0101] It can be seen from the data of application examples 1-6 and comparative application examples 1-2 that when the weight ratio of honey of camellia japonica, oat extract, myrobalan extract and schisandra chinensis extract is (2-3):(0.1-0.2):(0.5-1):(0.1-0.2), the soothing and repairing effect of the emulsion is better.

[0102] It can be seen from the data of application example 1 and application examples 7-8 that when the soothing and repairing composition is added to the emulsion at a concentration of 2-6 wt%, the skin moisture content improvement rate, a* value improvement rate and TEWL value improvement rate are all higher, indicating that the soothing and repairing effect of the emulsion is better.
