Description

Technical Field

[0001] This invention relates to a hygiene product, and more particularly to a disposable hygiene care essence, its preparation method, and its application. Background Technology

[0002] Disposable feminine hygiene products such as antibacterial (or bacteriostatic) washes, wipes, sanitary napkins, panty liners, and sanitary underwear come into close contact with the vulvar skin. Due to the prolonged exposure to a moist and warm environment, the vulva may experience redness, swelling, pain, itching, discomfort, and unpleasant odor. Furthermore, prolonged contact with chemical substances can easily irritate and cause allergies, and may induce inflammation and discomfort. These problems seriously affect women's quality of life. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a coconut oil antibacterial and deodorizing essence, its preparation method and application, which can inhibit bacteria and deodorize, soften the skin, relieve itching, improve redness and soothe sensitivity.

[0004] The technical solution adopted by this invention to solve its technical problem is: A coconut oil antibacterial and deodorizing essence is made from the following raw materials in weight percentages: 12-50% coconut oil, 4-10% butylene glycol, 0.1-2% sodium hyaluronate, 1-5% panthenol, 2-5% lactic acid, 2-5% potassium lactate, 1.5-6% emulsifier, 0.1-0.6% 4-tert-butylcyclohexanol, 0.1-6% ectoine, 0.1-6% ergothioneine, 1-2% non-irritating preservative composition, and the remainder being pure water. The non-irritating preservative composition is NAGO® A91 and EverGuard™ HP in equal proportions, and the emulsifier is a mixture of Eumulgin® SG and Cosmedia® SP in any proportion.

[0005] The preparation steps of the above-mentioned coconut oil antibacterial and deodorizing essence are as follows: (1) Preparation of component A: Mix the above weight of butanediol and EverGuard™ HP evenly, put them into a stirring container, heat to 50-60°C while stirring, keep warm and stir until the material is completely dissolved and the appearance is clear and transparent, cool down to below 40°C to room temperature, add the above weight of NAGO® A91 and stir evenly for later use.

[0006] (2) Preparation of component B: First, add the above weight of pure water to the stirring container, and then add the above weight of sodium hyaluronate, ectoine and ergothioneine one by one. Stir and dissolve before use.

[0007] (3) Preparation of component C: Add the above weight of coconut oil, 4-tert-butylcyclohexanol, Eumulgin® SG and Cosmedia® SP into a mixing container and stir evenly for later use.

[0008] (4) Mixing and emulsification: First, add component B to the main mixing tank and keep it at 50-60 rpm. While stirring, add component C and continue stirring for 15-20 minutes. Then, turn on the homogenizer at 2000-3000 rpm and homogenize for 10-15 minutes. After stopping the homogenizer, continue stirring at 50-60 rpm. Then, add component A, panthenol, lactic acid, and potassium lactate. After adding all the components, stir and mix at 50-60 rpm for 15-20 minutes to obtain the coconut oil antibacterial and deodorizing essence.

[0009] A disposable hygiene product, such as sanitary napkins, panty liners, and sanitary underwear, contains the aforementioned coconut oil antibacterial and deodorizing essence.

[0010] A disposable hygiene product care substrate is prepared by coating a fiber layer with the above-mentioned coconut oil antibacterial and deodorizing essence, and then drying, slitting, drawing and winding it to obtain the disposable hygiene product care substrate, which is used to prepare disposable hygiene products.

[0011] A disposable hygiene product using the above-mentioned disposable hygiene care substrate includes, from top to bottom, a skin-adhesive surface layer, a disposable hygiene care substrate, an absorbent resin layer, a dust-free paper layer, a release paper layer, and a PE film layer.

[0012] A coconut oil antibacterial and deodorizing personal care product, such as essence, wipe base, or wash, contains the aforementioned coconut oil antibacterial and deodorizing essence.

[0013] A disposable hygiene product, wherein the skin-contact layer of the hygiene product is sprayed with the above-mentioned coconut oil antibacterial and deodorizing essence, and dried after spraying to obtain the disposable hygiene product.

[0014] The beneficial effects of this invention are as follows: The coconut oil antibacterial and deodorizing essence contains natural antibacterial and soothing active ingredients. These ingredients work synergistically to inhibit bacteria and remove odors, while also reducing skin sensitivity, alleviating discomfort, relieving itching, and reducing stinging and burning sensations. Coconut oil has a high content of lauric acid and glyceryl monolaurate, which can disrupt the cell membranes / capsules of bacteria, viruses, and fungi, leading to their lysis and death. The synergistic effect of lactic acid and potassium lactate maintains a strictly acidic pH, which inhibits microbial growth and reduces odor production. Butylene glycol and sodium hyaluronate improve skin elasticity and provide moisturizing effects, enhance the skin's barrier function, and protect the skin from environmental damage. 4-tert-butylcyclohexanol is a precisely targeted "instant soothing master," accurately and quickly relieving skin stinging, burning, and other neurosensitive reactions. Ectoine is a natural amino acid derivative extracted from halophilic bacteria, renowned for its exceptional stability and comprehensive cellular-level protective capabilities, offering multidimensional protection, moisturizing and repairing, and anti-inflammatory and soothing effects. Ergothioneine is a natural antioxidant; clinical studies show that ergothioneine supplementation can significantly improve skin's antioxidant levels, collagen density, and elasticity, playing a role in anti-aging, anti-inflammation, and cell protection. Disposable hygiene products made with this essence can inhibit bacteria and deodorize, soften skin, relieve itching, improve redness, and soothe sensitivity. Topical skincare products made with this essence provide skincare benefits, inhibiting harmful bacteria, building a natural biological protective film on the skin's surface, and offering anti-inflammatory, soothing, repairing, anti-itch, and redness-reducing effects, leaving skin hydrated and firm. Detailed Implementation

[0015] In this embodiment, NAGO® A91 is a cosmetic preservative produced by Aizhuo Biotechnology, characterized by high safety and low irritation. EverGuard™ HP is a mild preservative synergist and antioxidant with low irritation, commonly used in sensitive skin-friendly products, infant skincare products, and post-medical aesthetic repair products. It enhances the overall safety of the formulation by balancing preservative requirements with gentleness. Coconut oil has a high content of lauric acid and glyceryl monolaurate, which can disrupt the cell membranes / capsules of bacteria (such as Staphylococcus aureus and Propionibacterium acnes), viruses (enveloped viruses), and fungi (such as Candida albicans), leading to their lysis and death. Coconut oil, along with lactic acid and potassium lactate, maintains a strictly acidic pH in the system (harmful bacteria such as Escherichia coli and Salmonella typically thrive in neutral or alkaline environments). The acidic environment inhibits their reproduction, reducing odor by suppressing microbial growth. Butylene glycol and sodium hyaluronate improve skin elasticity and provide moisturizing effects, enhance the skin's barrier function, and protect the skin from environmental damage. 4-T-butylcyclohexanol is a precisely targeted "instant soothing master," providing precise and rapid relief from skin irritation, burning, and other neurosensitive reactions. Ectoin is a natural amino acid derivative extracted from halophilic bacteria, renowned for its excellent stability and comprehensive cellular-level protection, offering multidimensional protection, moisturizing repair, anti-inflammatory, and soothing effects. Ergothioneine is a natural antioxidant; clinical studies show that ergothioneine supplementation can significantly improve skin's antioxidant levels, collagen density, and elasticity, playing a role in anti-aging, anti-inflammation, and cell protection. Eumulgin® SG is a nonionic surfactant and emulsifier from BASF. Cosmedia® SP is a sodium polyacrylate thickener, emulsifier, and stabilizer from BASF, offering excellent skin feel and formulation compatibility.
