Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of eye care, and relates to a C-shaped steam hot compress eye mask and a preparation method thereof. BACKGROUND

[0002] The steam hot compress eye mask is a convenient eye care product, generates sustained heat through the oxidation-reduction reaction of the heating material and oxygen in the air, and forms hot steam by using the water released in the reaction process, so that the effect of eye hot compress and steam SPA is realized, is widely used to provide a warm and comfortable care experience for users, and helps to relax the eye.

[0003] In the prior art, such products still have many deficiencies in structural design, safety, and composite functions, and the heating core of a conventional steam eye mask is usually arranged in a left-right symmetrical manner by two independent heating sheets, which has a potential risk of scalding the eyeball. CN121196828A discloses a low-temperature high-steam self-heating eye mask based on hydrogel, which realizes stable and abundant steam output under low-temperature conditions through the cooperation of the hydrogel functional layer and the self-heating body.

[0004] However, this design does not solve the core safety problem of precise avoidance of the eyeball part, and this scheme mainly focuses on the optimization of physical hot compress performance and does not involve how to stably and efficiently combine with active ingredients such as traditional Chinese medicine to realize synergistic effect. In order to enhance the product function, the prior art attempts to add traditional Chinese medicine or plant extracts in the eye mask, and a common method is to directly spray plant essential oil on the surface layer of the eye mask, but the essential oil sprayed on the surface layer is easy to volatilize or oxidize during storage, has poor stability, and has limited durability, stability and targeting of efficacy.

[0005] Therefore, it is urgent to develop a new type of steam hot compress eye mask which ensures eye safety, realizes stable and efficient delivery of care ingredients, and provides sufficient and comfortable steam hot compress. SUMMARY

[0006] In view of the deficiencies of the prior art, the purpose of the present application is to provide a C-shaped steam hot compress eye mask and a preparation method thereof.

[0007] To achieve the above purpose, the present application provides the following technical solutions: A C-shaped steam hot compress eye mask, comprising: A C-shaped connected heating core, comprising a non-heating area and a heating area; The non-heating area is in the form of a circular arc and is located at the position corresponding to the eyeball of the wearer of the eye mask, and is used to effectively avoid heating the eyeball; The heat generating area comprises a heat generating material, the heat generating material comprises the following components in parts by weight: iron powder 20-45 parts, carbon powder 15-25 parts, sodium chloride 3-10 parts, water absorbing resin 15-25 parts, polypropylene fiber 2-8 parts, sodium polyacrylate 1-5 parts, vermiculite 5-20 parts, and purified water 20-25 parts; The eye patch further comprises a separate medicine chamber, which is separated from the heat generating core by a diaphragm, forming a double package structure. The medicine chamber contains a compound traditional Chinese medicine powder, the compound traditional Chinese medicine powder comprises the following components in parts by weight: salvia miltiorrhiza powder 10-15 parts, lycium barbarum polysaccharide 8-12 parts, honeysuckle extract 6-8 parts, chamomile volatile oil microcapsule 5-8 parts, menthol 3-5 parts, beta-cyclodextrin-cassia anthraquinone inclusion compound 2-3 parts, and medicinal carrier 20-40 parts.

[0008] The above scheme of the present application, by arranging the C-shaped connected heat generating core and the non-heat generating area thereof, can accurately avoid the eyeball part, fundamentally prevents the eyeball scalding risk possibly caused by the traditional eye patch, and realizes safe hot compress.

[0009] The position for receiving steam hot compress by wearing the connected eye patch of the present application includes orbicularis oculi (upper and lower), levator labii superioris alaeque nasi, brow ridge, corrugator supercilii, and canthus, and the warm effect generated by the design is helpful to promote local blood circulation and muscle relaxation, thereby relieving the tightness and fatigue state of the eye area, making the eye more relaxed, and the hot compress area of the ordinary eye patch is relatively limited.

[0010] The specific proportion of the heat generating material provides a stable heat source through the synergistic effect of iron powder, carbon powder and sodium chloride, the combination of water absorbing resin and vermiculite effectively locks water and generates abundant steam, and the polypropylene fiber and sodium polyacrylate ensure that the material body is fluffy and the reaction is uniform, thereby realizing the comfortable hot compress experience of constant temperature, large amount of steam and long duration.

[0011] The double package structure is adopted to physically isolate the heat generating core and the medicine chamber, which not only ensures the independence and stability of the traditional Chinese medicine components and avoids the deterioration or reaction possibly caused by direct mixing with the heat generating material, but also allows the steam and heat generated by the heat generation to carry the active components of traditional Chinese medicine through the diaphragm to jointly act.

[0012] In the compound traditional Chinese medicine powder, the combination of salvia miltiorrhiza, lycium barbarum polysaccharide, honeysuckle and other components aims to bring comfortable feeling to the eye area; the chamomile volatile oil microcapsule releases and relieves; the menthol brings cool feeling and assists the penetration of components; the beta-cyclodextrin-cassia anthraquinone inclusion compound helps to improve the stability and mildness of components. The components synergistically work in the steam hot compress environment, and specifically relieve the tightness and fatigue of the eye, and improve the comfort.

[0013] Preferably, the preparation method of the chamomile volatile oil microcapsule is as follows, S2-1: gelatin and gum arabic are mixed in a mass ratio of 1: (1.1-1.2) and added to deionized water at 50-60 DEG C, ultrasonic mixing for 10-30 min, to obtain a wall material solution with a total mass concentration of 5%; S2-2: adding tocopheryl acetate and acetyl hexapeptide-8 to chamomile essential oil to obtain a core material, adding the core material to the wall material solution under stirring, and performing high-speed shearing emulsification at a speed of 8000-15000 rpm, an emulsification time of 3-8 min, and an emulsification temperature of 40-50 DEG C, to obtain an emulsion A; S2-3: adding a citric acid solution under continuous stirring until the pH is 3.8-4.2, continuously stirring for 20-40 min, using an ice water bath to reduce the system temperature to 5-10 DEG C and maintaining for 30-60 min, and then filtering, washing, and drying to obtain the chamomile volatile oil microcapsules.

[0014] The above scheme of the present application uses gelatin-gum arabic complex coagulation method combined with the specific process parameters to prepare chamomile volatile oil microcapsules, which can significantly improve the thermal stability and durability of the volatile oil, prevent it from rapidly evaporating or oxidizing during the heating and storage process of the eye mask. Microencapsulation realizes the slow-release effect, so that the soothing aroma and efficacy can be uniformly and continuously released during the entire hot compress process, prolonging the effective action time.

[0015] Preferably, the mass ratio of chamomile volatile oil, tocopheryl acetate and acetyl hexapeptide-8 in S2-2 is (98-100):1:(2-4).

[0016] The above scheme of the present application adds tocopherol acetate and acetyl hexapeptide-8 into chamomile volatile oil in a specific ratio, and tocopherol acetate can act as an efficient antioxidant to preferentially protect volatile oil and peptide components from being oxidized and destroyed during preparation and use, thereby ensuring the efficacy stability thereof; compared with natural vitamin E, the esterification structure has higher thermal stability, can better resist temperature fluctuations and the continuous warm environment during the use period of the eye mask, and provides a persistent and reliable protective barrier for volatile oil. The addition of acetyl hexapeptide-8 further enriches the experience dimension of the microcapsule, which itself helps to improve the smoothness and comfort of the skin, and with its affinity characteristics, it assists in nursing the local skin condition, so that the appearance of the periorbital skin is smoother. When the eye mask is heated, the steam promotes the gradual release of the microcapsule wall, and tocopherol acetate can be released together with acetyl hexapeptide-8 and chamomile active substances, not only to play an antioxidant role, but also to indirectly prolong the action time of the volatile oil components that are prone to loss, thereby achieving stable and sustained release of the efficacy. At the same time, tocopherol acetate and chamomile volatile oil have a synergistic effect, the natural fragrance of chamomile volatile oil helps to relax the mind, relieve tension, and soothe the tightness and discomfort of the periorbital skin caused by fatigue; tocopherol acetate helps to protect the periorbital skin in a warm environment, and synergistically improves the overall comfort and gentle care experience of the periorbital skin, and acetyl hexapeptide-8 can enhance the affinity and overall comfort experience during use, and synergistically with the physical action of hot compress, thereby helping to improve the temporary fine line appearance caused by dryness and fatigue, and improving the comfort and overall pleasant feeling of the periorbital skin, so that the hot compress process is more gentle and moisturizing.

[0017] Preferably, the total mass ratio of the core material to the wall material in S2-2 is 1: (2.5-3.5).

[0018] The above scheme of the present application controls the total mass of the core material and the wall material to be 1: (2.5-3.5), which can achieve the best balance between ensuring high encapsulation rate and appropriate oil load, and ensure the sustained release performance of the microcapsule and the efficacy of the final product.

[0019] Preferably, the preparation method of the β-cyclodextrin-cassia anthraquinone inclusion compound is as follows, The cassia anthraquinone extract is added to an ethanol solution and ultrasonically mixed for 10-30 min to obtain solution B, and solution B is added to a 50-70℃ β-cyclodextrin aqueous solution under stirring, stirred at 50-70℃ for 2-6h, then cooled to 2-8℃ and continue to stir for 4-8h, and then filtered, washed and dried to obtain the β-cyclodextrin-cassia anthraquinone inclusion compound.

[0020] The above scheme of the present application can effectively embed anthraquinone components by using the cavity of the beta-cyclodextrin, and the formed inclusion compound can significantly improve the physical stability of the anthraquinone components, so that the anthraquinone components can be uniformly dispersed in the medicine powder and realize stable and controllable slow release in the humid and hot steam environment generated by the eye mask, thereby prolonging the efficacy time. Meanwhile, the inclusion process can effectively shield the degradation of active ingredients caused by light and heat, thereby ensuring the durability and stability of the drug efficacy.

[0021] Preferably, the mass ratio of the beta-cyclodextrin to the semen cassiae anthraquinone extract is (8-10):1.

[0022] The above scheme of the present application controls the mass ratio of the beta-cyclodextrin to the semen cassiae anthraquinone extract to be (8-10):1, thereby avoiding the waste of beta-cyclodextrin while ensuring high inclusion rate and drug loading, so that the inclusion compound has appropriate solubility and controllable release characteristics under hot compress conditions, and the safety and efficacy are optimized.

[0023] Preferably, the medicinal carrier is a mixture of soluble starch and beta-cyclodextrin in a mass ratio of (7-9):1.

[0024] The above scheme of the present application uses a specific ratio mixture of soluble starch and beta-cyclodextrin as the medicinal carrier. The soluble starch provides good flowability and filling property; the beta-cyclodextrin can not only act as a carrier, but also further include other volatile or hydrophobic components in the formula, thereby reducing the loss of the components during storage, stabilizing the overall formula, and assisting the uniform dispersion and release of the formula components.

[0025] Preferably, the diaphragm is a breathable medical non-woven fabric.

[0026] The above scheme of the present application selects a breathable medical non-woven fabric as the diaphragm, which can reliably separate the heating material and the traditional Chinese medicine powder in two independent chambers to ensure the integrity of the double-package structure, and allow the water vapor and heat generated by the heating to efficiently penetrate due to the good air and moisture permeability, so that the active components of the traditional Chinese medicine can act on the skin around the eyes together, thereby realizing steam hot compress therapy.

[0027] Preferably, the intermediate non-heating area is in the shape of a circular arc with a diameter of 1.8 cm, and the center point distance of the non-heating area of the heating core is 7.7 cm, which is suitable for wearers with different face shapes.

[0028] The above scheme of the present application sets the center point distance of the non-heating area of the heating core to be 7.7 cm, which is optimized based on a large amount of human face measurement data. This size can adapt to the facial contours of most adult men and women, and ensure that the non-heating area can accurately cover the eyeball, while the heating area can fully fit the orbicularis oculi muscle, the temple and other key areas around the eye socket, thereby improving the universality, comfort and targeting of the hot compress.

[0029] Preferably, a preparation method of a C-shaped steam hot compress eye mask, comprising the following steps: S10-1: Iron powder, carbon powder, sodium chloride, water-absorbing resin, polypropylene fiber, sodium polyacrylate, vermiculite and purified water are mixed according to the formula proportion, and a connected heating core is formed by injection molding; S10-2: Salvia miltiorrhiza powder, lycium barbarum polysaccharide, honeysuckle extract, chamomile volatile oil microcapsule, menthol, β-cyclodextrin-cassia seed anthraquinone inclusion compound and a pharmaceutical carrier are mixed according to the formula proportion to prepare a composite traditional Chinese medicine powder, the composite traditional Chinese medicine powder is filled into a breathable non-woven fabric medicine bag and sealed to form a medicine chamber, the medicine chamber and the connected heating core are compounded through a diaphragm, and the compound is sealed and packaged using an outer packaging material to prepare the C-shaped steam hot compress eye mask.

[0030] The outer packaging material is selected from a composite film such as PE / PP or PET / AL / PE, and the oxygen transmission rate is controlled to be 1000-3000 cm3 / (m2·24h·atm) to realize physical regulation of the heating oxidation reaction rate and ensure that heat is slowly and uniformly released, so that the surface temperature of the eye mask heating body is stably maintained in a comfortable and safe range.

[0031] The beneficial effects of the present application are: The present application adopts a C-shaped connected heating core structure, the built-in arc-shaped non-heating area of which can accurately avoid the eyeball and eliminate the risk of scalding, and target safe hot compress is realized. Meanwhile, the structure can comprehensively cover the key areas such as the orbicularis oculi muscle, eyebrow ridge and canthus, and the warm effect generated thereby helps muscle relaxation, thereby relieving eye fatigue and improving comfort.

[0037] Example 1 As shown in the drawings, a C-shaped steam hot compress eye mask includes: Figures 1-6 A C-shaped integrated heating core includes a non-heating area and a heating area. The non-heating area is in the shape of a circular arc and is located at the position corresponding to the eyeball of the wearer of the eye mask, so as to effectively avoid heating the eyeball. The middle non-heating area is in the shape of a circular arc with a diameter of 1.8 cm, and the center point distance of the non-heating area of the heating core is 7.7 cm, which is suitable for wearers with different face shapes. The C-shaped steam hot compress eye mask also has an externally connected ear-hanging structure, which can fix the eye mask to the ears of the user when worn, ensuring that the eye mask is stably attached to the eye, avoiding slipping, and at the same time reducing the pressure on the nose bridge and the eye, improving the wearing comfort and the fit.

[0038] The heating area includes a heating material, which includes the following components by weight: 35 parts of iron powder, 20 parts of carbon powder, 5 parts of sodium chloride, 10 parts of water-absorbing resin, 5 parts of polypropylene fiber, 3 parts of sodium polyacrylate, 12 parts of vermiculite, and 22 parts of purified water.

Preferably, the medicine chamber is located between the heating material and the inner side of the eye mask and is separated from the heating core by breathable medical non-woven fabric, which can prevent the direct contact between the traditional Chinese medicine components and the heating material, avoid the deterioration of active substances due to heating, and allow the water vapor and heat generated by heating to pass through the membrane, achieving the synergistic effect of steam hot compress.

[0040] ​In specific use, after the eye mask is opened, oxygen in the air penetrates the breathable outer layer and contacts the heat-generating material. The iron powder in the heat-generating material is oxidized to release heat in the presence of the sodium chloride electrolyte and moisture. The carbon powder promotes electron transfer and accelerates the reaction. The water-absorbing resin locks the moisture, and after being heated, it stably releases steam, so that the surface temperature of the heat-generating body is stably maintained in a comfortable temperature range. The heating is uniform and moderate, the duration is controllable, and the mild and long-lasting hot compress effect is achieved. The eye mask can be safely applied without the risk of burns.

[0041] The pharmaceutical carrier is soluble starch and β-cyclodextrin in a mass ratio of 8:1.

[0054] Example 11 The mass ratio of β-cyclodextrin to senna anthraquinone extract was 10:1, and the remaining steps were consistent with Example 1.

[0055] Comparative Example 1 No tocopherol acetate was added in the preparation of chamomile volatile oil microcapsules, and the remaining steps were consistent with Example 1.

[0056] Comparative Example 2 No acetyl hexapeptide-8 was added in the preparation of chamomile volatile oil microcapsules, and the remaining steps were consistent with Example 1.

[0058] Comparative Example 4 No β-cyclodextrin inclusion treatment was performed on senna anthraquinone, and the remaining steps were consistent with Example 1.

[0059] Performance test In a constant temperature and humidity chamber (20±1℃, relative humidity 46%), temperature and steam test was performed using a thermocouple temperature recorder and a precision electronic balance.

[0060] Ingredient stability and release test: the content change of chamomile volatile oil characteristic ingredient (bisabolol) in the eye mask before and after use was determined using gas chromatography. The cumulative release percentage of senna anthraquinone characteristic ingredient (chrysophanol) in the receiving liquid was determined at 30 minutes using Franz diffusion cell to simulate hot compress conditions (45℃ water bath).

[0061] Franz diffusion cell combined with high performance liquid chromatography (HPLC) was used for determination, the receiving pool was pH 5.5 phosphate buffer (containing 1% Tween 80), the temperature was maintained at 45℃, and the cumulative penetration amount of traditional Chinese medicine ingredients (salvianic acid in Danshen powder, mannose in Lycium barbarum polysaccharide) was determined at 120 minutes.

[0062] Recruit 200 subjects with long-term visual fatigue, randomly group using different samples, fill out the questionnaire after use, score on "fatigue relief degree", "overall comfort level".

[0063] Example 1 exhibits excellent and balanced comprehensive performance in steam amount, continuous heating time, active ingredient retention rate, sustained release performance, and fatigue relief and user comfort. All key indicators of all examples are maintained at a high level, indicating that the product performance is stable and reliable within the limited parameter range.

[0064] The chamomile retention rate of Comparative Example 1 is significantly lower than that of Example 1, proving that the addition of a small amount of tocopherol acetate plays a key role in protecting heat-sensitive volatile oil components. The comfort satisfaction of Comparative Example 2 decreased significantly, and the fatigue relief efficiency also decreased synchronously, proving that the introduction of acetyl hexapeptide-8 has a positive effect on improving the overall use experience and subjective comfort. The chamomile retention rate and comfort of Comparative Example 3 are the worst, proving that the microencapsulation technology is indispensable for maintaining component stability and improving use comfort.

[0065] The anthraquinone release rate of Comparative Example 4 is much higher than that of Example 1, showing explosive release, and its comfort is the lowest, which confirms that the inclusion technology can effectively regulate the release behavior, avoid potential irritation caused by too fast release, and thus improve the sense of safety and sustained release efficacy.

[0066] The cumulative penetration amount of danshensu and mannose in Examples 1-11 is at a relatively high level, which directly proves that the composite traditional Chinese medicine powder described in the present application can better transmit the components in the composite powder under simulated eye mask use conditions.

[0067] Further experimental verification: improvement effect around the eyes To objectively evaluate the experience effect of the eye mask of the present application during use, the following professional instruments are used for detection: 1. Eye area warm feeling and relaxation effect evaluation after use A laser Doppler blood flow instrument (PeriFlux System 5000) is used to detect the microcirculation blood flow velocity of the eye area of 30 subjects before and after using the eye mask of the present application (Examples 1, Comparative Examples 1-3).

[0068] The results show that Example 1 obtained the best user feedback in the test, and the subjects generally expressed that there was a warm diffusion feeling around the eyes, and the muscle relaxation feeling was obvious.

[0069] 2. Eye area skin comfort evaluation after use The skin moisture content and transdermal water loss of the subjects before and after using the eye mask were detected using a skin moisture tester (Corneometer CM825) and a Tewameter (Tewameter TM300).

[0070] The results show that the use of Example 1 can effectively bring about the moisturizing and relaxing feeling of the periorbital skin. The general feedback of the subjects is that the periorbital skin is more moisturized and comfortable, and the original dry and tight feeling is significantly relieved.

[0071] 3. Visual perception evaluation of the appearance of the periorbital skin after use A PRIMOS-CR skin rapid three-dimensional imaging system was used to conduct a 14-day half-face control test on 30 female volunteers aged 35-50 years, one side using Example 1 and the other side randomly using a comparative product, and the reduction rate of wrinkle volume in the crow's feet area was analyzed.
