[0001] The present application belongs to the technical field of skin care products, and relates to a composition, in particular to a composition for promoting skin repair and healing and application thereof. BACKGROUND

[0002] The skin barrier, as a shield for healthy skin, plays a very important role in maintaining the stability of the human body internal environment. When the skin barrier is damaged, the skin is prone to sensitive sub-stable state, and even causes specific dermatitis, psoriasis and other skin problems. With the continuous expansion of the global sensitive skin population, the public's attention to sensitive skin care is gradually increasing. In order to cope with sensitive skin, repairing the skin barrier is the key development direction in the field of scientific research and the field of skin care product application.

[0003] The damage of the skin barrier not only leads to skin water loss, dryness, itching, sensitivity, but also causes the occurrence of skin diseases such as eczema, psoriasis, acne and the like. In recent years, more and more people have damaged skin barrier due to excessive cleaning, long-term wearing of masks, exfoliation, ultraviolet rays and the like. Developing a composition for promoting skin repair and healing is an effective and safe method, and has very important research significance.

[0004] Therefore, there is an urgent need to design a new composition for promoting skin repair and healing in order to overcome at least part of the above-mentioned defects existing in the prior art. SUMMARY

[0008] As an embodiment of the present application, the mass ratio of the Selaginella pulvinata extract, the Castanea sativa seed extract, the Spirodela polyrrhiza extract and the erythritol is (2-5):(1-3):(2-4):(3-8).

[0009] According to another aspect of the present application, the following technical scheme is adopted: the composition for promoting skin repair and healing is used for preparing skin care products.

[0010] As an embodiment of the present application, the skin care product is an ice film.

[0011] As an embodiment of the present application, the ice film comprises 5-22% of the composition for promoting skin repair and healing by mass percentage, and 78-95% of a skin care auxiliary material matrix by mass percentage.

[0012] As an embodiment of the present application, the skin care auxiliary material matrix comprises 0.1-10% of a humectant by mass percentage, 0.5-3% of a thickening agent by mass percentage, 0.8-1.5% of a preservative by mass percentage, 0.02-0.2% of a daily use fragrance by mass percentage, and the balance is deionized water.

[0013] As an embodiment of the present application, the humectant comprises at least one of sodium hyaluronate, butylene glycol, hexylene glycol, pentylene glycol, glycerol, and dipropylene glycol.

[0014] The thickening agent comprises at least one of carbomer, xanthan gum, acrylate / C10-30 alkyl acrylate crosspolymer, gum arabic, polymer EMT-10, sodium acrylate / sodium acryloyldimethyl taurate, acrylate / C10-30 alkyl acrylate crosspolymer copolymer, hydroxyethyl cellulose, and ammonium acryloyldimethyltaurate / beheneth-25 methacrylate crosspolymer.

[0015] The preservative comprises at least one of phenoxyethanol, ethylhexylglycerin, farnesol, sodium benzoate, pentylene glycol, and hexylene glycol.

[0016] As an embodiment of the present application, the preparation method of the ice film comprises the following steps:

[0017] The preparation method of the ice film comprises the following steps:

[0018] Step S1, the thickening agent is completely wet-dispersed in deionized water to obtain a mixed solution;

[0019] Step S2, the humectant and the preservative are added to the mixed solution of step S1, and heated to 80-85°C, so that they are completely dissolved by stirring;

[0020] Step S3, the temperature is lowered to 40-45°C, the composition for promoting skin repair and healing and the daily use fragrance are added to the mixed solution prepared in step S2, so that they are completely dissolved by stirring, to obtain the ice film with the effect of promoting skin repair and healing.

[0021] The composition for promoting skin repair and healing and the application thereof have the advantages that the stability of active ingredients is maintained, and the composition has obvious effect of increasing skin barrier.

[0022] The compositions of the present application are complementary in mechanism of action, and have instant cooling effect when used in combination. The present application enhances the metabolic pathway of natural moisturizing factor NMF by increasing ceramide and epidermal lipid production, increases the water content of the stratum corneum, synergistically enhances the barrier function of the skin by activating cell activity, regulating the adhesion and desquamation balance of epidermal cells, accelerating the renewal of stratum corneum cells, and improving the cohesion of the stratum corneum.

[0023] In one use scenario of the present application, the present application selects Selaginella pulvinata extract, Castanea sativa seed extract, Spirodela polyrrhiza extract, erythritol as a composition for promoting skin repair and healing effect, wherein erythritol, when dissolved in water, its molecules or ions need to overcome the attraction between each other to leave the solid surface and diffuse into the solvent, thereby absorbing a large amount of heat, showing good cooling effect, having instant cooling effect, and being more mild and non-irritating than traditional cooling agents, and also promoting keratinocyte maturation, strengthening the epidermal barrier, and reducing transepidermal water loss; Selaginella pulvinata extract, known as "nine-death grass", enhances the metabolic pathway of natural moisturizing factor NMF, increases the amount of ceramide and neutral lipid synthesis, thereby strengthening the stratum corneum barrier; Castanea sativa seed extract triggers mitochondrial autophagy to produce cell energy, thereby increasing ATP production required for correct keratinocyte function, promoting PADs enzyme activity (peptide arginine deiminase), thereby promoting the adhesion and desquamation balance of the stratum corneum and maintaining the homeostasis of the epidermis; Spirodela polyrrhiza extract, Spirodela polyrhiza is outstanding because its plant cell wall is rich in APG, which is a unique pectin with water-binding capacity, so it can achieve endogenous water locking, and also activates the biological levers of skin moisturizing (aquaporin, osmotic pressure transporter, natural moisturizing factor), thereby providing instant and long-lasting moisturizing for the surface and deep layers of the skin. The four synergistically enhance the barrier function of the skin.

[0024] In the present application, the erythritol component has special physicochemical properties such as freezing point depression, boiling point elevation, and high osmotic pressure, in addition to its low hygroscopicity and low viscosity characteristics when dissolved, making it easier to reduce or control water activity. Therefore, it is a good antifreeze and is used to reduce and control the water activity of the product, thereby improving the preservation of the product. BRIEF DESCRIPTION OF DRAWINGS

[0091]

[0092]

[0093]

[0094] From the results of Table 5, the ice film prepared in the examples and the control example and the blank example has a score of 0 at 0.5h, 24h, 48h, and no adverse reactions to the skin, indicating that the composition and the ice film product involved in the present application are safe and non-irritating to the skin.

[0095] 2. Stability test

[0096] Test sample: Examples 1-3;

[0097] Test method: Internal control standard: observe the appearance and color for three months, pH.

[0098] Table 6 Stability Test Results

[0099]

[0100]

[0101] In Table 6, W represents weeks, M represents months, and cycle represents a cycle of temperature from 50°C to -15°C once a day.

[0102] The ice film prepared in the examples has no significant changes in color, viscosity, and pH under high and low temperatures or light conditions within three months, indicating that the ice film of the present application has good stability.

[0103] 3. Test experiment of skin stratum corneum water content and trans-epidermal water loss rate

[0104] Test instrument: multifunctional skin tester from Germany CK Company, probe model Tewameter TM300.

[0105] Test conditions: constant temperature and humidity environment, temperature 23±1°C, humidity 50%±5%, before testing, the subjects sit in the environment for at least 30 minutes.

[0106] Recruit 180 suitable subjects, 90 males and 90 females. Randomly divide them into 18 groups, 10 people in each group.

[0107] The skin moisture content (%) and TEWL (%) of the left and right cheeks of the subjects were measured using a skin tester, and the average of 10 values was used as the data of the skin moisture content (dO) and TEWL (dO) of the left and right cheeks. After washing the face, the ice film obtained in Examples 1, 2, 3 and Comparative Examples 1-14 and the blank example was applied to the face once a day in the morning and evening, and the skin moisture content and TEWL of the left and right cheeks of the subjects were measured using a skin tester every week for 4 weeks. The data of Tl (1 week), T2 (2 weeks), T3 (3 weeks) and T4 (4 weeks) were recorded, and the average of 10 persons in each group was calculated. The change rates of the skin moisture content and TEWL were calculated, and the results are shown in Tables 7 and 8.

[0108] Change rate of skin moisture content and TEWL = (average of skin moisture content and TEWL of 10 persons in each group after using the test sample - average of skin moisture content and TEWL of 10 persons in each group before using the test sample, i.e., T0) / average of skin moisture content and TEWL of 10 persons in each group before using the test sample, i.e., T0.

[0109] The results are shown in Tables 7 and 8.

[0110] Table 7 Test results

[0111]

[0112]

[0113] Table 8 Test results

[0114]

[0115]

[0116] As can be seen from Tables 7 and 8, the ice film containing the skin healing and protection promoting components obtained in Examples 1-3 can effectively increase the skin moisture content and reduce the TEWL. When one, two or three of the components are added to the ice film of Comparative Examples, the skin moisture content and TEWL are increased to some extent, but the effect is far less than that of Examples 1-3, which proves that the combination of the components produces a synergistic effect. The ice film composition obtained in the blank example has little effect on increasing the skin moisture content and reducing the TEWL. It is shown that the ice film containing the skin healing and protection promoting components has the effects of increasing the skin moisture content and reducing the TEWL, and the four components have a synergistic effect, so as to strengthen the barrier function of the skin.

[0117] 4. Human trial evaluation experiment

[0118] Experimental method: ice films prepared by example 1, 2, 3, control example 1-14 and blank example were selected as experimental samples, and the test subjects were evaluated respectively.

[0119] 180 subjects aged 30-50 were selected and randomly divided into 18 groups, 10 people in each group. 10 groups of subjects used ice films prepared by example 1, 2, 3 and control example 1-14 and blank example. Method of use: after cleansing, use once a day in the morning and evening, massage and absorb, and sensory evaluation is carried out according to the use feeling: each group of subjects scores according to the sensory evaluation, and the average score of each group is taken (full score 10 points, 7 points and above are satisfactory). The results obtained by each group are shown in Table 9:

[0120] Table 9 test results

[0121]

[0122]

[0123] As can be seen from Table 9, the ice films obtained by examples 1-3 of the present application have better instantaneous cooling and immediate moisturizing effects than the control examples and the blank example. It can also be seen that the instantaneous cooling and immediate moisturizing effects are not obvious when erythritol is used alone or combined with one or two kinds of functional components. Only when the four kinds of functional components are combined can the effects be synergistically enhanced, thereby strengthening the barrier function of the skin.

[0124] In summary, the composition for promoting skin repair and healing and its application proposed by the present application can maintain the stability of active ingredients, and the composition has obvious effects of promoting skin repair and healing.
