Description

Technical Field

[0001] This invention relates to the field of breast repair technology, specifically a breast repair patch with whitening and antioxidant effects. Background Technology

[0002] Breast reconstruction requires a customized approach based on individual circumstances. Common causes include implant displacement, unsatisfactory post-operative appearance, or tissue atrophy. Repair methods typically include implant adjustment, autologous fat grafting, scar revision, or a combination of these treatments. A doctor must assess the breast tissue condition, skin elasticity, and overall health needs to develop a plan. If capsular contracture, displacement, or rupture occurs, the implant may need to be removed or replaced, and the implantation depth adjusted. For autologous fat grafting, fat survival rate and the possibility of multiple grafts must be considered. If tissue defects or skin laxity exist, a combination of suspension surgery or flap transplantation may be used to improve the appearance. Regarding breast repair patches, these are topical patches designed for women's breast care, typically used to relieve breast pain, unclog milk ducts, promote blood circulation, or aid in post-operative recovery. However, the following issues may arise during the normal production process of these repair patches:

[0003] (1) During the production of repair patches, the single composition results in a single function of the repair patches, which reduces the functionality and applicability of the repair patches; (2) During the production of repair patches, the mixing of raw materials can easily lead to the failure to remove internal air bubbles, which reduces the production quality and coating uniformity of the product; (3) When testing the finished product, only the final product is inspected, which results in the failure to inspect the raw materials and semi-finished products in the production process, which reduces the safety and environmental protection of the entire production process. Summary of the Invention

[0004] The purpose of this invention is to provide a breast repair patch with whitening and antioxidant effects, in order to solve the problems mentioned in the background art regarding the production process of the repair patch: (1) During the production process of the repair patch, due to the single ingredient, the function of the repair patch is relatively simple, thereby reducing the functionality and applicability of the repair patch; (2) During the production process of the repair patch, when mixing the raw materials, it is easy to cause internal air bubbles to not be removed, thereby reducing the production quality and coating uniformity of the product; (3) When testing the finished product, only the final finished product is inspected, resulting in the lack of inspection of raw materials and semi-finished products in the production process, which reduces the safety and environmental protection of the entire production process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a breast repair patch with whitening and antioxidant effects, the percentage of its constituent components being as follows:

[0006] Nicotinamide: 45%;

[0007] Vitamin E and its derivatives: 45%;

[0008] Repair agent: 5%;

[0009] Cream: 2%;

[0010] Thickener: 1%;

[0011] Penetration enhancer: 1%;

[0012] Fragrance essential oil: 1%.

[0013] Preferably, the penetration enhancer is azone, and the cream is made from an emulsion system consisting of an oil phase, an aqueous phase, and an emulsifier.

[0014] Preferably, the repair agent is a combination of ceramide and Centella asiatica extract.

[0015] A method for preparing a breast repair patch with whitening and antioxidant effects includes the following production steps:

[0016] S1, Formula Design

[0017] S1.1 Determine the ingredient ratio: Niacinamide: 45%, Vitamin E and its derivatives: 45%, Repairing agent: 5%, Cream: 2%, Thickener: 1%, Penetration enhancer: 1%, Fragrance essential oil: 1%; S1.2 Matrix composition: ① Hydrogel patch, ② Cream patch;

[0018] S2. Substrate Selection and Treatment

[0019] S2.1 Substrate selection: ① Non-woven fabric, ② Bio-fiber, ③ Spunlace fabric, gel film; S2.2 Cutting design to conform to the breast curve: ① Crescent shape, ② Butterfly shape; S2.3 Substrate treatment: ① Substrate disinfection, ② Substrate hydrophilic treatment, ③ Substrate special coating treatment.

[0020] S3, Production Process

[0021] S3.1 Ingredient Preparation and Mixing: Accurately weigh raw materials according to the formula. ① Dissolve / heat the oil and water phases separately, then emulsify and mix. Active ingredients are usually added at a suitable temperature to avoid high-temperature damage. Strictly control the temperature, stirring speed, and time to ensure homogeneity. ② Degas: Remove air bubbles generated during stirring to ensure product appearance and coating uniformity. S3.2 Coating and Lamination: ① Apply the mixed gel evenly to the substrate, covering it with a release film. ② Apply the paste quantitatively and evenly to the substrate, also covering it with a release film. Release film, S3.3, Cutting and packaging: ① Cutting: Cut large sheets of coated material into designed individual patch shapes; ② Inner packaging: Pack individual patches into barrier packaging bags such as aluminum foil bags. This step must be carried out in a clean environment; ③ Sealing: Cold sealing to ensure good sealing of the packaging bags and prevent evaporation, contamination, and oxidation of the essence; ④ Sterilization: Sterilize the final product with Co60 irradiation. Reducing the risk of microorganisms is crucial. The sterilization effect and residue need to be verified; ⑤ Outer packaging: Pack the inner-packaged patches into the outer box and label them.

[0022] S4. Quality Inspection

[0023] S4.1 Raw Material Inspection: Each batch of raw materials is inspected for appearance, physicochemical properties, and microbial limits. Only those meeting the standards are used. S4.2 Semi-finished Product Inspection: During production, the mixture is tested for pH value, viscosity, color, and odor. S4.3 Finished Product Inspection: ① Physicochemical Properties: Appearance, odor, pH value, viscosity, coating amount / net content, cold and heat resistance; ② Microbiological Properties: Total bacterial count, total mold and yeast count, thermotolerant coliforms, Staphylococcus aureus, Pseudomonas aeruginosa; ③ Active Ingredient Content: Actual content of key whitening agents and antioxidants is tested to ensure consistency with claims and stability; ④ Preservative Challenge Test: The finished product undergoes preservative efficacy testing to ensure effective inhibition of microbial growth within the shelf life; ⑤ Skin Irritation / Allergy Test: Repeated-damage patch test on humans to demonstrate the product's mildness.

[0024] Preferably, the microbial indicators are obtained by plate counting and enrichment culture and identification, the active ingredient content is obtained by high performance liquid chromatography, and the preservation challenge test is obtained by inoculating microorganisms.

[0025] Preferably, the stability test of the breast repair patch includes accelerated stability testing, including 40℃±1℃, 75%RH±5%RH, for 3-6 months, and long-term stability testing, including 25℃±2℃, 60%RH±5%RH, covering the entire shelf life, examining changes in appearance, odor, pH value, viscosity, active ingredient content, and microbial indicators during the storage period to determine the shelf life.

[0026] Preferably, the Co60 irradiation is a technique that uses gamma rays emitted by the radioactive isotope cobalt-60 for sterilization, disinfection, and material modification.

[0027] Preferably, the degassing in step S3 is performed using ultrasonic degassing.

[0028] The preferred ultrasonic degassing method refers to the generation of high-frequency vibrations when ultrasonic waves propagate in a liquid, forming microbubbles. Under the action of sound pressure, the bubbles expand and collapse violently, generating local high pressure and shock waves, which disrupt the dissolution balance of gas in the liquid, causing dissolved gas to precipitate and aggregate into large bubbles that escape.

[0029] The application of a breast repair patch with whitening and antioxidant effects involves directly applying the patch to the breast area. Through phototherapy, niacinamide, vitamin E, and their derivatives promote skin repair.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. This invention, through the determination of the formula by staff, involves adding cream thickeners, penetration enhancers, and fragrance essential oils. The weight percentages are determined to be 45% niacinamide, 45% vitamin E and its derivatives, 5% repair agent, 2% cream, 1% thickener, 1% penetration enhancer, and 1% fragrance essential oil. Then, hydrogel patches and medicated patches are used as the base material, enabling the repair patch to have multiple functions, focusing on barrier repair, soothing and anti-allergy, whitening and anti-oxidation, improving the repair quality, thereby enhancing the functionality and applicability of the repair patch.

[0032] 2. In this invention, the raw materials are accurately weighed according to the formula, and then the oil phase and water phase are dissolved and heated separately, and then emulsified and mixed. The active ingredients are usually added at a suitable temperature to avoid damage from high temperature. The temperature, stirring speed and time are strictly controlled to ensure homogeneity. During the stirring process, ultrasonic defoaming is used to remove the air bubbles generated during stirring, ensuring the appearance of the product and the uniformity of the coating, thereby improving the production quality of the repair patch.

[0033] 3. Before the start of the work, each batch of raw materials is tested for appearance, physicochemical indicators, and microbial limits. Only those that meet the standards can be used. Then, during the production process, the pH value, viscosity, color, and odor of the mixture are tested. Only those that meet the standards can continue production. Finally, the finished product is tested for physicochemical indicators. Thus, the packaging process implements strict inspection and control of each step of the production process, improving hygiene and environmental protection control during the production process.
