[0026] The raw materials or reagents used in the embodiments and comparative examples of the present invention are all purchased from mainstream manufacturers in the market. For those without specified manufacturers or concentrations, they are raw materials or reagents of analytical purity grade that can be obtained conventionally. As long as they can achieve the expected effects, there are no special restrictions. The instruments and equipment used in this embodiment are all purchased from major manufacturers in the market. As long as they can achieve the expected effects, there are no special limitations. For those without specified specific technologies or conditions in this embodiment, they are carried out according to the technologies or conditions described in the literature in this field or according to the product instructions.

[0027] The first object of the present application provides a natural plant wet wipe, which includes a plant additive solution and a substrate for carrying the plant additive solution. Among them, the plant additive solution includes the following raw materials in mass percentages: glycerol 0.5-5%, pH regulator 0.1-2%, natural plant preservative 0.5-5%, and the balance is plant hydrosol. The plant hydrosol is a natural solvent and has a certain antibacterial effect. Using the plant hydrosol as an antibacterial matrix can act synergistically with the natural plant preservative. The natural plant preservative has the effects of anti-corrosion and sterilization, and can promote the antibacterial effect of the plant hydrosol to achieve the purpose of synergistic enhancement; glycerol mainly plays the roles of moisturizing and stabilizing the formulation system, and the pH regulator is used to adjust the acid-base level of the plant additive solution or / and synergistically prevent corrosion and inhibit bacteria. It should be noted that the balance is plant hydrosol, that is, the plant hydrosol is the only solvent and does not contain deionized water or other solvents.

[0028] Among them, the substrate is non-woven fabric. For example, it can be pure cotton spunlace non-woven fabric, plant fiber non-woven fabric, MPM non-woven fabric, etc. that can be used as the substrate of the wiping towel, and it is not uniquely limited here. In other embodiments, materials made of natural fibers or / and fibers of natural origin can also be selected to make the substrate, so as to form a natural plant wet wipe with pure plant components.

[0029] In some specific embodiments, the plant additive solution includes the following raw materials in mass percentages: glycerol 1-4%, pH regulator 0.5-1.5%, natural plant preservative 2-4%, and the balance is plant hydrosol.

[0030] In some specific embodiments, the plant additive solution includes the following raw materials in mass percentages: glycerol 2-3%, pH regulator 0.75-1.25%, natural plant preservative 2.5-3.5%, and the balance is plant hydrosol.

[0031] Furthermore, the natural plant preservative includes orange flower extract and grapefruit seed extract.

[0032] Neroli extract is rich in volatile components such as linalool and limonene, which have inhibitory effects on common pathogenic bacteria such as Staphylococcus aureus and Escherichia coli. It can regulate the growth environment of microorganisms, extend the shelf life of wet wipes after opening, and play a role in antioxidant and auxiliary anti-corrosion. In addition, flavonoids (such as hesperidin) in neroli can relieve skin flushing and irritation, are suitable for sensitive skin or baby wet wipes, promote skin barrier repair, reduce dryness after wiping, and improve the comfort of use.

[0033] Components such as naringenin and limonin in grapefruit seed extract can damage the cell membranes of microorganisms, are effective against bacteria, fungi and even some viruses, can scavenge free radicals, prevent the oxidation and deterioration of wet wipe liquid, and thus achieve the purpose of antioxidant and anti-corrosion.

[0034] The synergistic effect among plant hydrosol, neroli extract and grapefruit seed extract can cover a more comprehensive variety of microorganisms, achieve the effect of antibacterial and anti-corrosion, and all three are natural plant components, having the advantages of mildness, soothing, low irritation and high safety.

[0035] In some specific embodiments, in terms of mass percentage, the plant additive solution comprises the following raw materials: glycerol 0.5 - 5%, pH regulator 0.1 - 2%, neroli extract 0.5 - 2.5%, grapefruit seed extract 0.5 - 2.5%, and the balance is plant hydrosol.

[0036] In some specific embodiments, the pH regulator is at least one of lactic acid and sodium citrate.

[0037] In a specific embodiment, the pH regulator is lactic acid.

[0038] In a specific embodiment, the pH regulator is sodium citrate.

[0039] In a specific embodiment, the pH regulator is lactic acid and sodium citrate.

[0040] Among them, lactic acid is a natural organic acid with the effect of regulating pH. It can damage the bacterial cell membrane and inhibit enzyme activity by reducing the environmental pH value, and has significant inhibitory effects on Gram-positive bacteria (such as Staphylococcus aureus), Gram-negative bacteria (such as Escherichia coli) and some fungi. The compounding and synergy of lactic acid, neroli extract, grapefruit seed and plant hydrosol promote the antibacterial effect of plant hydrosol and achieve synergistic enhancement. Lactic acid can be well compatible with components such as plant extracts, improve the stability of wet wipe liquid, and avoid stratification or precipitation. In addition, lactic acid also has hygroscopicity, can help wet wipes retain moisture, slow down the evaporation of liquid, and extend the use time after opening.

[0041] Sodium citrate, as a pH regulator and buffer, can adjust the pH value of the wet wipe solution to an appropriate range, and it can stabilize the pH value of the wet wipe solution, preventing the pH value from fluctuating due to other components or external factors. Keeping the wet wipe at an appropriate pH is beneficial for the skin to absorb moisture and play a moisturizing role. In addition, sodium citrate can combine with metal ions on the surface of bacteria, destroying the cell membrane structure of bacteria, thereby inhibiting the growth and reproduction of bacteria, which is beneficial to enhancing the antibacterial performance of the wet wipe.

[0042] In some specific embodiments, in terms of mass percentage, the plant additive solution includes the following raw materials: 0.5 - 5% glycerin, 0.1 - 2% lactic acid, 0.5 - 2.5% orange flower extract, 0.5 - 2.5% grapefruit seed extract, and an appropriate amount of sodium citrate to adjust the pH to between 5 and 6, with the balance being plant hydrosol.

[0043] In some specific embodiments, the liquid content of the natural plant wet wipe is ≥ 4 times.

[0044] Among them, the calculation formula for the liquid content is as follows:

[0045]

[0046] The liquid content of 4 times effectively guarantees the wateriness of the wet wipe and can ensure that the plant additive solution effectively supports the antibacterial and anti-corrosion properties of the natural plant wet wipe.

[0047] Furthermore, the plant hydrosol is tea tree hydrosol. The extraction process of the tea tree hydrosol in this embodiment is as follows:

[0048] Raw material treatment: Sterilize fresh tea tree leaves with microwave and ultrasonic waves, and then crush the leaves into fine particles at low temperature in a nitrogen environment;

[0049] Extract hydrosol: Perform low-temperature and high-pressure extraction on the crushed leaves, and perform segmented condensation on the extracted components to obtain tea tree essential oil and a crude sample of tea tree hydrosol;

[0050] Purification treatment: Filter the crude sample of tea tree hydrosol successively with molecular sieve and nanofiltration membrane to obtain high-purity tea tree hydrosol; finally, sterilize and encapsulate to obtain the required tea tree hydrosol.

[0051] Among them, using microwave and ultrasonic for sterilization treatment instead of conventional high-temperature cooking sterilization is beneficial to retaining the natural components in the tea tree leaves; crushing the tea tree leaves in a nitrogen environment to isolate the interaction between the tea tree leaves and oxygen can effectively prevent the tea tree leaves from being oxidized during the crushing process.

[0052] Perform low-temperature high-pressure extraction on the crushed leaves. Specifically, put the crushed leaves into a high-pressure device and flush them with hot water (around 100 °C) in a cycle to extract their active ingredients. Perform fractional condensation on the active ingredients. Specifically, first perform high-temperature condensation on the hot gas of the mixed ingredients. At this time, tea tree essential oil is condensed and collected. Then perform low-temperature condensation. At this time, the required pure tea tree dew is condensed and collected for standby.

[0053] The obtained pure tea tree dew can be filtered by molecular sieve to remove heavy metals in the pure tea tree dew, and then large particulate matter in the pure tea tree dew can be filtered through a nano-film, and finally a high-purity pure tea tree dew liquid is obtained. In addition, the tea tree essential oil obtained by extraction can be stored and applied to the production of other products.

[0054] Supercritical carbon dioxide and natural bacteriostatic agents are used for the sterilization treatment of high-purity pure tea tree dew.

[0055] It should be noted that the above-mentioned glycerol, sodium citrate, lactic acid, orange blossom extract, and grapefruit seed extract are all purchased from Yizhan (Shanghai) Chemical Co., Ltd. The pure tea tree dew can also be directly purchased from a plant extract supplier. The pure tea tree dew in this embodiment is directly prepared by the production side using the above preparation process.

[0057] S1. Prepare materials according to the mass percentages of the raw materials of the plant additive solution for standby;

[0058] S2. Heat the pure tea tree dew to 40 - 45 °C, then sequentially add glycerol, lactic acid, and orange blossom extract, and stir at a constant temperature for 20 min; cool down to 30 °C;

[0091] Detect each example, comparative example and blank sample respectively, and analyze the test results.

[0092] The following details the test steps and methods for each test item:

[0093] Toxicological detection:

[0094] Refer to the Disinfection Technical Specification or GB15979-2024, and conduct skin allergy, skin irritation, acute oral toxicity, eye irritation and mucosal irritation tests.

[0095] Test steps for anti-corrosion and antibacterial performance:

[0096] 1. Prepare a bacterial suspension: Use the target bacterial species to prepare a bacterial suspension with an appropriate concentration. The bacterial species selected are such as: bacteria (Escherichia coli), yeast (Candida albicans), mold (Aspergillus niger);

[0097] 2. Sample treatment: Mix the wet wipe solution sample with the bacterial suspension and dilute it in a certain proportion.

[0098] 3. Cultivation: Inoculate the mixed solution on a nutrient agar plate and incubate it at 37°C for 24 hours.

[0099] 4. Calculation of antibacterial rate: After the cultivation is completed, count the number of colonies in the sample treatment group and the plate control group, and calculate the antibacterial rate according to the formula.

[0100] Test standard: The antibacterial rate should be ≥99%, indicating that the wet wipe has a significant antibacterial effect.

[0101] Stability detection:

[0102] The test method refers to GB15979-2024, and store it at least at 54°C for 14 days to simulate reaching a 1-year shelf life.

[0103] Test standard: The total number of microorganisms ≤100 CFU / g, meeting the requirements of GB15979-2024.

[0104] Skin feel detection:

[0105] 1. Selection of subjects: Use volunteers or experimental animals as the test subjects.

[0106] 2. Sample treatment: Apply the wet wipe solution on the skin of the subjects (such as the inner forearm) and cover it with a patch for a certain period of time (such as 24 hours).

[0107] 3. Observation of reactions: Observe whether the skin shows redness, itching or other allergic reactions within the specified time.

[0108] 4. Recording of results: Record the reaction conditions and evaluate them.

[0109] Test standard: There should be no obvious irritant reaction and the skin feel should be refreshing.

[0110] Based on the above detection content, the relevant results are summarized in Table 1:

[0111] Table 1

[0112]

[0113]

[0114] As can be seen from Table 1, a natural plant wet wipe prepared in Examples 1-3 has good toxicological, anti-corrosion and antibacterial effects, is not irritating to the skin, and is suitable for infants and sensitive skin. From the test results of Example 2, it can be obtained that the natural plant wet wipe made of raw materials with intermediate ratio has good toxicological properties and stability, and good anti-corrosion and antibacterial effects, and has a fresh and non-irritating skin feel. The tests of Example 1, Example 2 and Example 3 of this embodiment show that orange flower extract and grapefruit seed extract have a synergistic promoting effect on the anti-corrosion and antibacterial properties of tea tree hydrosol. However, adding too little orange flower extract and grapefruit seed extract will result in insufficient stability of the wet wipe, and the microbial content may exceed the standard; adding too much orange flower extract and grapefruit seed extract will make the skin feel of the wet wipe sticky and reduce the comfort of use.

[0115] Comparing Comparative Example 1 with Example 1 and Comparative Example 4 with Example 2, it can be seen that the orange flower extract and grapefruit seed extract in the technical solution of the present invention can synergistically enhance the effect with tea tree hydrosol. The three are compounded, having anti-corrosion and antibacterial capabilities, and can effectively improve the stability of the wet wipe product; only adding tea tree hydrosol without the synergistic enhancement of orange flower extract and grapefruit seed extract, its antibacterial, anti-corrosion capabilities and stability cannot meet the product requirements; only adding orange flower extract and grapefruit seed extract without tea tree hydrosol as the antibacterial matrix, its antibacterial, anti-corrosion capabilities and stability also cannot meet the product requirements.

[0116] Comparing Comparative Example 2 with Example 2, it can be seen that only adding orange flower extract has limited synergistic effect on the antibacterial and anti-corrosion properties of tea tree hydrosol, and its antibacterial, anti-corrosion capabilities and stability cannot meet the product requirements.

[0117] Comparing Comparative Example 3 with Example 2, it can be seen that only adding grapefruit seed extract has limited synergistic effect on the antibacterial and anti-corrosion properties of tea tree hydrosol, and its antibacterial, anti-corrosion capabilities and stability cannot meet the product requirements.

[0118] The above embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
