Description

Technical Field

[0001] This invention belongs to the technical field of menstrual care products, specifically relating to a method for producing herbal rose core menstrual care products. Background Technology

[0002] Menstrual care products are essential hygiene items for women during their menstrual period, and their performance directly affects women's comfort and health safety. Most existing menstrual care products focus on a single absorbent function, using a composite of superabsorbent polymers and ordinary fiber materials. While these can meet basic menstrual blood absorption needs, they have significant shortcomings in areas such as intimate care, antibacterial and deodorizing properties, and relieving menstrual discomfort.

[0003] During menstruation, a woman's private parts are in a sensitive and vulnerable state. Menstrual blood and secretions can easily breed bacteria, causing itching, odor, and even inflammation. Women may also experience menstrual cramps, cold uterus, and mood swings. Traditional rose-based menstrual care products simply add rose petal powder or fragrance, resulting in low retention of active ingredients, limited efficacy, and short-lived antibacterial effects. Furthermore, some products use chemically synthesized materials that have poor breathability and can easily cause skin allergies, failing to meet women's diverse and health-conscious needs for menstrual care products. In addition, existing product manufacturing processes often involve simple mixing and pressing, lacking protection for the stability of active ingredients. This leads to ingredient loss and efficacy degradation during storage and use; moreover, some materials are not biodegradable, causing environmental burden after use.

[0004] It is evident that providing a method for producing menstrual care products that integrates multiple herbal care ingredients, has both high absorption and long-lasting care effects, and is environmentally friendly is of great significance in the field of menstrual care products technology. Summary of the Invention

Compared with products containing only rose, the care effect is more comprehensive and significant, and it can effectively relieve menstrual pain, cold uterus, and problems such as vaginal itching and odor. 2. This invention uses a grafting modification technology of superabsorbent polymer and chitosan quaternary ammonium salt to prepare a modified material that has both high water absorption rate and long-lasting antibacterial properties. This solves the problem of separation of water absorption and antibacterial functions in traditional products. Moreover, the modified material has good compatibility with the active ingredients of the herbs, which can effectively prevent the loss of active ingredients and prolong the durability of the product's care efficacy. 3. This invention utilizes processes such as low-temperature freeze-drying, macroporous resin purification, and low-temperature curing to maximize the retention of active ingredients in raw materials and enhance the product's care efficacy. Simultaneously, the use of hot melt adhesive dot coating and gamma-ray irradiation sterilization processes ensures product structural stability, sterility, and safety, enabling large-scale production and possessing broad market application prospects.
