Description

TECHNICAL FIELD

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

[0002] Sensitive skin is a common sub-health state of problem skin, which refers to a high reaction state of skin under physiological or pathological conditions. When the skin is stimulated by physical, chemical, mental factors, excessive skin care, staying up late, work and life pressure, and long-term use of electronic equipment radiation, etc., it is easy to appear subjective symptoms such as burning, stinging, itching, tightness, and accompanied by objective signs such as adverse erythema, scales, and capillary dilation. In severe cases, it may even appear redness, skin rash, and uneven skin color. According to the "National Skin Status Survey" released by the Dermatology Branch of the Chinese Medical Association, the sensitive skin population is showing explosive growth, reaching as high as 72.08%.

[0003] Chinese patent CN202211452583.2 discloses a composition, mask liquid and mask for sensitive skin repair. The composition for sensitive skin repair includes the following components: radix scutellariae extract, chamomile extract, agave extract, kava root extract, gentian extract, and centella asiatica extract. The mask liquid includes the following components: sensitive skin repair composition, auxiliary efficacy system, thickening system, moisturizing system, oil system, buffer system, preservative system, and purified water. The mask cloth is preferably aloe composite fiber mask cloth. This mask lacks comprehensive planning of the internal mechanism of sensitive skin and cannot effectively form a repair function for sensitive skin. Moreover, the preservative system in it can stimulate the skin and cause higher sensitivity risk for sensitive skin.

[0004] Therefore, there is an urgent need for a moisturizing mask with repairing effect for sensitive skin without preservatives, which can effectively repair sensitive skin while moisturizing, repairing skin barrier, anti-inflammatory, and regulating skin sensation. SUMMARY

[0005] The present application provides a moisturizing mask with repairing effect and a preparation method thereof to solve the problem of higher sensitivity risk for sensitive skin caused by existing preservative-containing masks, and to effectively form a repair function for sensitive skin while moisturizing, repairing skin barrier, anti-inflammatory, and regulating skin sensation.

[0006] The specific technical solutions of the present application are as follows: The present application aims to provide a moisturizing mask with repairing effect and a preparation method thereof, the mask comprising a sensitive skin repairing mask liquid and a mask cloth, wherein the mask liquid comprises the following components in percentage by mass: a sensitive skin repairing composition 5-10%, an auxiliary efficacy system 0.1-5%, a thickening system 0.2-0.8%, a moisturizing system 5-10%, a grease system 0.2-0.8%, a buffer system 0.1-0.2%, and purified water 70-80%.

[0007] Further, the sensitive skin repairing composition comprises the following components in percentage by mass: Chamomile oil 20-40%, tea tree oil 10-20%, gentian extract 10-40%, centella asiatica extract 10-20%, 4-tert-butylcyclohexanol 5-10%, butanediol 10-30%, conditioning agent 5-10%, and water in balance.

[0008] The chamomile oil is obtained by extracting the flower of chamomile plant by steam distillation, has antibacterial, antioxidant, anti-inflammatory, soothing and anti-allergic biological activities, can inhibit the induced skin allergy, enhance the resistance of capillary vessels, inhibit the capillary permeability and has anti-inflammatory effect, and has good application in calming, soothing and pain relieving.

[0009] The tea tree oil is obtained by extracting fresh leaves and tender branches, contains rich chemical components, and the main active components include p-menth-1-ol-4, 1-8-eucalyptol, alpha-terpinene, gamma-terpinene and the like, which endow the tea tree oil with broad-spectrum antimicrobial activity, bacteriostasis, anti-inflammatory, insect repellent and acaricidal effects and the effect of promoting wound healing.

[0010] Gentian is a perennial herbaceous plant of gentian family, and the gentian extract can achieve the effects of anti-allergy and anti-irritation by inhibiting and reducing inflammatory reaction, and has the effects of relieving itching, detumescence, anti-inflammation and analgesia.

[0011] Centella asiatica is the whole plant of centella asiatica of the family Umbelliferae, and the active components of the centella asiatica extract are asiaticoside and hydroxyl asiaticoside, which have excellent repairing effects such as scar repair, dermis repair and sunburn repair, help to repair the damaged skin and promote the smoothness of the skin.

[0012] The 4-tert-butylcyclohexanol interacts with other components in the system, can quickly relieve the nerve sensory activity of sensitive skin symptoms, reduce the burning and stinging sensation, and help to relieve the excessive reaction of the skin and reduce the sensitive symptoms.

[0013] The conditioning agent in the present application is a component capable of conditioning the skin and coordinating the function of each component in the composition, and the conditioning agent comprises phosphatidyl and ethanolamine sphingomyelin.

[0014] Further, the weight ratio of the chamomile oil to the tea tree oil is (1.5-2.5):1.

[0015] Preferably, the weight ratio of the chamomile oil to the tea tree oil is 2:1.

[0016] Further, the content of the gentian extract and the centella asiatica extract is not less than 30wt% of the total mass of the chamomile oil and the tea tree oil.

[0017] Preferably, the content of the gentian extract is 35wt% of the total mass of the chamomile oil and the tea tree oil, and the content of the centella asiatica extract is 42wt% of the total mass of the chamomile oil and the tea tree oil.

[0018] Further, the weight ratio of the phosphatidyl ethanolamine to the cardiolipin is (2-3):1.

[0019] Preferably, the weight ratio of the phosphatidyl ethanolamine to the cardiolipin is 2.4:1.

[0020] The applicant finds that by adjusting the weight ratio between the chamomile oil and the tea tree oil, the anti-allergic effect of the composition can be significantly improved, the irritation of sensitive skin to lactic acid and the like can be significantly reduced, the stinging sensation can be reduced, and a better anti-allergic soothing effect can be achieved. The chamomile oil contains ingredients such as bisabolene, α-farnesene, linalool, etc., which can have good intermolecular forces such as hydrogen bonds with the effective components in the tea tree oil, can promote each other, accelerate the penetration speed of active ingredients in the system to the inside of the skin, and at the same time can reduce the expression of inflammatory factors such as interleukin-1 and leukotrienes in the skin, inhibit the occurrence of inflammatory reactions, avoid the destruction of the skin barrier by the above inflammatory factors, thereby helping to reduce the redness, stinging, itching and other allergic inflammation of sensitive skin caused by external stimulation, and accelerating the healing process of the skin. Moreover, when the weight ratio of the chamomile oil to the tea tree oil is 2:1, the anti-allergic effect of the composition is most significant, and when the weight ratio changes greatly, the anti-allergic effect of the composition is significantly reduced. This may be because when the weight ratio is 2:1, the synergistic effect between the chamomile oil and the tea tree oil reaches the best balance, which can best promote the efficacy of the components in the system, and when the weight ratio changes, the interaction between them is destroyed, thereby affecting the efficacy.

[0021] Applicants found in the process of completing the present application that the content of gentian extract and centella asiatica extract in the composition is closely related to the content of chamomile oil and tea tree oil. When the content ratio is within a certain range, the anti-allergic effect of the composition can be significantly improved. However, when the content of gentian extract and centella asiatica extract is too low or too high, the anti-allergic effect of the composition will be affected. Gentian extract is rich in bioactive ingredients with specific structures, and centella asiatica extract is rich in triterpenoids such as gentiopicroside and asiatic acid. These bioactive ingredients can promote the expression of filaggrin and caspase-14 in the corneal cells of the skin to some extent, which helps to promote the connection between keratin fibers, maintain the flat state of keratinocytes to form a keratin film, and also participates in the terminal differentiation of keratinocytes, assists filaggrin to form a complete stratum corneum, and thickens the stratum corneum, thereby improving the skin barrier and reducing sensitivity to the outside world.

[0022] Applicants found that when a certain proportion of phosphatidyl ethanolamine and cardiolipin are used as conditioning agents in the present application, the stability of the composition can be greatly improved, and the composition has good storage performance at high and low temperatures. The occurrence of stability problems such as delamination and precipitation during storage in different environments is effectively avoided. In particular, when the weight ratio of lecithin and dipalmitoyl phosphatidylcholine is 2.4:1, the effect is most significant. This may be because cardiolipin has a hydrophilic head and two hydrophobic tails, and has hydrophilic and hydrophobic amphiphilicity. Phosphatidyl ethanolamine also has a hydrophobic group and a hydrophilic group, and forms a bilayer micelle structure under the action of various components in the composition system. Due to the structural differences between phosphatidyl ethanolamine and cardiolipin, the micelles formed by them also have certain differences. These different micelles in the system can encapsulate different high-activity ingredients in the micelles formed by them, avoiding the deterioration of the ingredients under the stimulation of external light, bacteria and other components, and avoiding the occurrence of instability such as phase separation and precipitation during storage.

[0023] In order to further improve the stability and antibacterial effect of the composition, applicants found that modifying phosphatidyl ethanolamine can better improve the performance of the composition. The specific operation method for preparing modified phosphatidyl ethanolamine is as follows: S11: Add phosphatidyl ethanolamine and n-hexane to a reaction bottle, ultrasonic dispersion, ultrasonic frequency 40-60 kHz, time 5-10 min, then heat to 40-50℃; S12: adding sodium hypochlorite with phosphatidyl ethanolamine lipid mass of 10% to 20% to the mixed solution obtained in step S11, stirring uniformly, then slowly adding acetic acid with phosphatidyl ethanolamine lipid mass of 30% to 40%, adjusting pH to 3.5 to 4.5, and performing reaction, and after reaction is completed, discharging; S13: adding the material obtained in step S12 into a nano-carboxyl chitosan solution with mass concentration of 0.1 to 0.2%, and adding 0.1 mol / L HCl solution dropwise to control pH value to 4 to 4.5, stirring at 35 to 45℃ for 1.0 to 3.0h, separating the material, and after washing and freeze-drying treatment, obtaining modified phosphatidyl ethanolamine lipid.

[0024] Chitosan is commonly used as an organic antibacterial agent, and is widely used in the field of cosmetics due to its wide source, renewability, biocompatibility, non-toxicity, non-irritation, high and persistent antibacterial ability, wide antibacterial spectrum, safety and health. Moreover, chitosan can be directly added into the cosmetic formula as a moisturizing agent, thickening agent or stabilizing agent, etc. Due to its excellent safety and biocompatibility, it can not only improve the use feeling of the product, but also prolong the shelf life. In the present application, after the double bond part of phosphatidyl ethanolamine lipid is treated with aldehyde group, nano-carboxyl chitosan is grafted in situ on the phosphatidyl ethanolamine lipid, and the obtained modified phosphatidyl ethanolamine can better improve the stability and antibacterial effect of the composition, and prolong the shelf life of the product without additional addition of preservatives.

[0025] In addition, the applicant also found that the improvement of the stability of the composition by the conditioner composed of the above specific components is also related to the chamomile oil and tea tree oil in the system. When the content of chamomile oil or tea tree oil is too much or a component is missing, the stability is greatly affected. This may be due to the inclusion of alkyl chains of a certain length in the components, which allows these components to randomly intercalate between the micelles formed by the conditioner, reducing the influence of micelles on external stimuli, thereby further improving the stability of the micelles. At the same time, the applicant unexpectedly found that by adjusting the content of the conditioner components and chamomile oil and tea tree oil, the anti-allergic effect of the composition can be significantly improved. This may be due to the interaction between different structural micelles formed by the conditioner, which can encapsulate and gradually release the remaining components in the system, promote the formation of membrane proteins and tight junction proteins, and inhibit the expression of pro-inflammatory factors, thereby helping to improve the anti-allergic effect.

[0026] The sensitive skin repair composition of the present application proposes a full-effect mechanism for sensitive skin repair: while externally defending, reducing exogenous stimulation and sensitizing sources, internally anti-inflammatory and soothing, reducing nervous stress reaction and inflammatory reaction, and further strengthening the skin barrier repair and the oxidative stress ability.

[0027] Furthermore, the auxiliary efficacy system comprises one or more of cholesterol, Bifida ferment filtrate, and sodium hyaluronate.

[0028] Furthermore, the thickening system is one or more of xanthan gum, polyacrylate crosspolymer-6, hydroxyethyl cellulose, sclerotium gum, and carbomer.

[0029] Furthermore, the moisturizing system is one or more of glycerin, β-glucan, and EDTA-2Na.

[0030] Furthermore, the oil system is mainly composed of water-soluble oils, including one or more of water-soluble jojoba oil, PEG-octanoic acid, and caprylic acid triglycerides.

[0031] Furthermore, the buffer system comprises one or more of triethanolamine, sialic acid, lactic acid, and arginine.

[0032] Furthermore, the preparation method of the sensitive skin repair mask liquid is as follows: S1: First, add purified water and thickening system, then stir to disperse evenly; then add moisturizing system, oil system and auxiliary function system, heat to 80-90℃, keep warm and stir for 10-30 minutes; after the materials are completely dissolved, start cooling, continue stirring and cooling to 40-50℃, then add buffer system, stir for 3-10 minutes, the stirring speed during mixing is 100-500 r / min; S2: Add the sensitive skin repair composition, keep warm and stir for 5-20 minutes until the material is completely dissolved, continue stirring and cool down to 30-40℃, and the stirring speed during mixing is 1000-3000r / min. After the mask liquid sample passes the test, it is discharged for use.

[0033] Furthermore, the membrane fabric is composed of one or more of the following: natural cotton, bamboo fiber, non-woven fabric, silk, bio-fiber, and composite fiber.

[0034] Preferably, the membrane fabric is a calendula composite fiber membrane fabric, which is composed of 90% calendula fiber and 10% plant Tencel, and the calendula-like fiber in the membrane fabric is ≥0.85mg / kg.

[0035] Calendula, also known as marigold or calendula herb, not only has excellent antioxidant properties, but also has antibacterial, anti-inflammatory, detoxifying, and wound-healing effects, which can effectively help the skin rebuild its barrier function.

[0036] The beneficial effects of this invention are as follows: This invention provides a moisturizing facial mask with repairing effects and its preparation method. The mask liquid includes the following components: a sensitive skin repair composition, an auxiliary efficacy system, a thickening system, a moisturizing system, an oil system, a buffer system, and purified water. The sensitive skin repair composition includes the following components: chamomile oil, tea tree oil, gentian extract, centella asiatica extract, 4-tert-butylcyclohexanol, butylene glycol, phosphatidylethanolamine, and cardiolipin. By modifying the phosphatidylethanolamine ester and adjusting the weight ratio of lecithin and dipalmitoylphosphatidylcholine to 2.8:1 and the weight ratio of chamomile oil and tea tree oil to 2:1, the various components in the composition are coordinated to exert optimal anti-inflammatory, anti-allergic, analgesic, and repairing functions. While reducing exogenous stimulation, nerve stress response, and inflammatory response, it strengthens its own protective mechanism, repairs the skin barrier, and further enhances oxidative stress resistance. Furthermore, it possesses superior high and low temperature stability, allowing for long-term preservation without deterioration or inactivation even in harsh environments. Moreover, no additional preservatives are added in this invention, making it natural and safe, resulting in a gentler and non-irritating product that will not cause side effects such as dependence or drug resistance with long-term use.

[0046] The membrane fabric is made of calendula composite fiber, which consists of 90% calendula fiber and 10% plant-based Tencel. The amount of calendula-like fiber in the membrane fabric is ≥0.85mg / kg.

[0047] Effect Experiment: 1. Evaluation of moisturizing and hydrating effects The moisturizing and hydrating effects of products were evaluated by testing skin moisture content and water loss. During the skin moisture content and water loss measurement and evaluation process, indoor relative humidity and temperature were controlled. A total of 80 subjects, aged 20-55 years, were included.

[0048] (1) Test on the moisturizing and hydrating effect of face masks in a dry environment (ambient humidity 37%): Moisture content was tested using the CORNEOMETER capacitance method. The results were expressed as the rate of change of the set Moisture Measurement Value (MMV). Skin moisture content was measured in subjects 2, 4, 8, 12, and 24 hours after product use. The experimental instrument was a Corneometer CM825 (CK GmbH, Germany). The formula for calculating the rate of change in moisture content (%) was: Moisture content change rate (%) = (Tn - T0) / T0 * 100, where T0 is the skin basal data collection value at the last moment; Tn is the data collection value of the sample group at each time point. A higher rate of change in moisture content indicates a more significant moisturizing effect. The results are shown in Table 2.

[0049] Table 2: Change rate of facial moisture content in Examples 1-3 and Comparative Examples 1-5 (ambient humidity 37%) As shown in Table 2, the present invention achieves a more prominent synergistic and long-lasting moisturizing effect by adding chamomile oil and tea tree oil to the composition system. Furthermore, the addition of gentian extract and centella asiatica extract can enhance the synergistic and long-lasting moisturizing effect of the chamomile oil and tea tree oil system to a certain extent.

[0050] (2) Water Loss Test: Based on the diffusion principle discovered by A. Fick, the change in water vapor pressure on the adjacent skin surface was measured to assess the loss of skin surface moisture. Water loss was expressed as TEWL (Trans-Epidermal Water Loss), with units of g / hm2. The lower the value, the more significant the effect of the sample in preventing water loss and the more complete the skin barrier function. The change rate of skin water loss was measured after 1h, 4h, 8h and 24h of use of the composition sample by the subjects. The experimental instrument was: Tewameter TM300, CK GmbH, Germany. The formula for calculating the change rate of skin water loss was: Change rate of water loss % = (Tn-T0) / T0*100, where: T0 is the data collection value of the skin base when no sample was applied; Tn is the data collection value of the sample group at each time point. The lower the negative value of the change rate of water loss, the more significant the water-locking effect. The results are shown in Table 3.

[0051] Table 3: Change rate of facial moisture loss in Examples 1-3 and Comparative Examples 1-5 (ambient humidity 37%) As shown in Table 3, the chamomile oil, tea tree oil, gentian extract, and centella asiatica extract added to the composition system of the mask in this invention have a synergistic and long-lasting water-locking function. Furthermore, with the synergistic effect of 5-10% 4-tert-butylcyclohexanol, 10-30% butylene glycol, and conditioning agents, the long-lasting water-locking ability is even stronger. The synergistic skin repair function of the chamomile oil, tea tree oil, gentian extract, centella asiatica extract, 5-10% 4-tert-butylcyclohexanol, 10-30% butylene glycol, and conditioning agents in this invention can also effectively establish a complete skin barrier function. This is mainly reflected in the significantly reduced water-locking effect after the loss of chamomile oil in Comparative Example 1, which is caused by the disruption of the synergistic effect between chamomile oil and tea tree oil. The chamomile oil and tea tree oil in this invention have a synergistic ability to reduce water loss, and with the cooperation of the entire composition system, the ability to inhibit water loss is more prominent, and it also has a certain moisturizing effect.

[0052] 2. Evaluation of Repair Effect Test participants: 80 test subjects with dry or red facial skin were randomly divided into 8 groups of 10 people each; Group a used the formulation product of Example 1, Group b used the formulation product of Example 2, Group c used the formulation product of Example 3, Group d used the formulation product of Comparative Example 1, Group e used the formulation product of Comparative Example 2, Group f used the formulation product of Comparative Example 3, Group g used the formulation product of Comparative Example 4, and Group h used the formulation product of Comparative Example 5.

[0053] Test area: face Usage: After 40 days of use, a comprehensive evaluation will be conducted. The evaluation results will be based on the improvement of dry or red facial skin, and will be divided into excellent effect, good effect, average effect, and no effect.

[0054] Evaluation method: Questionnaire completion; The overall evaluation of the test results is shown in Table 4 below.

[0055] Table 4: Summary Table of Product Trial and Repair Effect Evaluation for Group AH 3. Evaluation of the degree of sensitivity to lactic acid stimulation The facial mask samples in Examples 1-3 and Comparative Examples 1-5 were subjected to a facial lactic acid stimulation efficacy evaluation test to observe the changes in the sensitivity of the participants' faces to lactic acid stimulation before and after using the above-mentioned composition samples.

[0056] The specific testing and evaluation method is as follows: Eighty individuals with sensitive skin aged 21-39 were invited, and samples from each embodiment were randomly assigned to groups of 10. During the experiment, half-face testing was conducted according to a randomization table. The left side of each group of subjects was covered with the mask sample from the above embodiments and comparative examples, while the right side was wiped with water. The nasolabial fold area was selected for the test. Test method: 50µl of a 12wt% lactic acid solution was taken and dropped onto a single-layer filter paper with a diameter of 1.0cm. The filter paper was then placed on the subject's face where the mask sample was applied. Subjects were asked about their stinging sensation after 3 minutes, and a 4-point scale was used for scoring (0 for no stinging, 1 for mild stinging, 2 for moderate stinging, and 3 for severe stinging). The subject's score was recorded as the initial lactic acid stimulation score W0 for that side. After the test, subjects were required to use the distributed mask sample as instructed, specifically once every two nights, with the left side of the face still covered with the sample and the right side wiped with water, for a continuous trial period of 4 weeks. Follow-up visits were required on days 14 and 28 of the trial. Under the same testing environment, the lactate stimulation scores W14 and W28 of the subjects were tested and recorded. The experimental results were taken as the average of each group (actual effective number of people), and the evaluation results are shown in Table 5 below.

[0057] Table 5. Results of Anti-sensitivity Test 4. Stability Evaluation The stability of the mask samples from Examples 1-3 and Comparative Examples 1-5 was tested, and the specific test methods are as follows: Heat resistance test: Place the sample in an electric thermostatic incubator at (40±1)℃ for 24 hours. After returning to room temperature, observe whether there are phenomena such as thinning, discoloration, layering and hardness changes to judge the heat resistance of the sample. Rating is 1 to 3, with grade 1 being the best heat resistance and grade 3 being the worst. Cold resistance test: The samples were placed in a refrigerator at (-10)℃±1℃ for 24 hours. After returning to room temperature, the samples were observed for phenomena such as thinning, discoloration, layering, and changes in hardness to determine their cold resistance performance. The samples were rated from 1 to 3, with 1 being the most stable and 3 being the least stable. The results are shown in Table 6 below.

[0058] Table 6 Performance Test Results The experimental results above show that the sensitive skin repair mask of the present invention uses plant ingredients such as chamomile oil, tea tree oil, gentian extract, and centella asiatica extract, as well as phosphatidylcholine and modified ethanolamine cardiolipin. Utilizing the interaction between these specific ingredients, it synergistically improves the sensitive skin barrier, relieves pain, absorbs heat and reduces swelling, and quickly eliminates allergy symptoms. Furthermore, through the ingenious combination of specific components and the regulation of their content, the composition coordinates the various components to exert optimal anti-inflammatory, anti-allergic, analgesic, and repairing functions. While reducing exogenous stimuli, nerve stress responses, and inflammatory responses, it strengthens the skin's own protective mechanisms, repairs the skin barrier, and further enhances oxidative stress resistance. At the same time, the composition possesses superior high and low temperature stability, allowing the product to be stored for a long time in harsh environments without deterioration or inactivation. It is preservative-free, naturally safe, and makes the product gentler and non-irritating, without causing dependence, drug resistance, or other side effects with long-term use.
