Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pet products, and particularly relates to a plant-based pet cleaning and bacteriostatic sanitary wet wipe and a preparation method thereof. BACKGROUND

[0002] Pet sanitary wet wipes, as an important product for daily cleaning and nursing, are widely used in pet body surface cleaning, bacteriostasis and deodorization, skin care and the like. However, the pet wet wipe products on the market still have many deficiencies: Most of the bacteriostatic components are chemical bacteriostatic agents such as quaternary ammonium salts and alcohols, which have significant effects but may cause toxic reactions when licked and ingested by pets, and long-term use may also cause skin irritation, allergies and damage to the barrier function; the pH of the skin of dogs and cats is 6.2-7.5 (weakly acidic to neutral), and the existing products either have a pH that is too alkaline (such as more than 8.0) and does not match the skin condition, or lack an effective buffer system, which causes the pH to drift easily, thereby damaging the skin lipid membrane and the microbial balance; the products mainly focus on cleaning and bacteriostasis, and ignore skin nourishment and repair, so it is difficult to solve the problems of dry skin, tightness and itching of pets after frequent cleaning; deodorization mainly relies on fragrances to mask ammonia, hydrogen sulfide and the like, which is a temporary solution and may irritate the sense of smell of pets; plant extract products have short shelf life and fast loss of active ingredients due to the complex composition, large difference in hydrophilicity and hydrophobicity, easy precipitation, layering and oxidative degradation, and the compatibility of non-woven fabric substrates and impregnation liquids is often ignored, which affects the function of effective components. It can be seen that the existing pet cleaning and bacteriostatic sanitary wet wipe products have many deficiencies and cannot meet the needs of pet fine care.

[0003] Therefore, it is urgent to develop a new type of pet cleaning and bacteriostatic sanitary wet wipe product with natural plant extracts as the core, which has multiple advantages such as efficient bacteriostasis, mild skin care, strong deodorization, safety, non-toxicity and good stability.

[0028] Comparative Example 1 The difference from Example 1 is that the composite plant antibacterial active agent is birch bark extract 4.5 parts.

[0029] Comparative Example 2 The difference from Example 1 is that 0.3 parts of benzalkonium chloride is used instead of the composite plant antibacterial active agent.

[0030] Comparative Example 3 The difference from Example 1 is that the pH adjusting buffer is removed, and deionized water is used directly for adjustment.

[0031] Comparative Example 4 The difference from Example 1 is that: ① the plant-based synergist is removed; ② the molecular weight of oat beta-glucan is 300 kDa; ③ the molecular weight of oat beta-glucan is 2,000 kDa; ④ the aloe vera gel freeze-dried powder is removed.

[0032] Comparative Example 5 The difference from Example 1 is that: ① the deodorant is tea polyphenol 0.6 parts; ② the deodorant is bamboo leaf extract 0.6 parts.

[0035] Test Example 1 (1) Bacteriostatic performance test Detection standard: GB / T 20944.3-2008 "Evaluation of antibacterial properties of textiles Part 3: shaking method".

[0036] Test strains: Staphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 8739), Candida albicans (ATCC 10231).

[0037] Calculation formula: Bacteriostatic rate (%) = (number of colonies in the control group-number of colonies in the sample group) / number of colonies in the control group x 100%.

[0038] The test results are as follows:

[0039] The bacteriostatic rate of Comparative Example 1 is only 91.5%, which proves that the synergistic effect of the composite formula is significant; although the bacteriostatic effect of Comparative Example 2 is close, there is a safety hazard; the bacteriostatic rates of Comparative Examples 3-6 are all lower than that of the embodiment due to defects in the formula or process.

[0040] (2) pH value determination Test method: Take 10 mL of the immersion liquid in a 50 mL beaker, equilibrate at room temperature for 30 min, and then use a calibrated pH meter (accuracy ± 0.01) to determine the pH value. The test temperature is 25±2℃.

[0041] The test results are as follows:

[0042] Comparative Example 3 has a high pH value due to the removal of the buffer, which may cause irritation to the skin of pets.

[0043] (3) Skin care effect test Skin hydration determination: Test method: Use an ex vivo dog skin model, wipe with a wet wipe, and then use a corneometer (CM825, Courage+Khazaka) to determine the skin capacitance value and convert it to skin hydration. The test site is the skin wiping site, and the determination is made 1 h after wiping. Each sample is repeated 6 times.

[0044] Calculation formula: Hydration improvement rate (%) = (hydration after treatment-hydration before treatment) / hydration before treatment x 100%.

[0045] The test results are as follows:

[0046] The comparative example 4 1 shows that the key role of the synergist is proved, and the comparative examples 4 2 and 4 3 show that the importance of the molecular weight range is proved; the comparative examples 6 and 7 show that the effects are lower than the examples.

[0047] (4) Deodorization performance test Target malodorous substances: ammonia (NH3), hydrogen sulfide (H2S), trimethylamine (TMA) Test method: The closed container method was used, and the standard concentration of malodorous gas was injected into a 5 L closed glass container, and the wet wipe sample (10 cm x 10 cm) was placed, and after being closed for 2 h, the residual concentration was determined by gas chromatography-mass spectrometry (GC-MS) or gas detection tube method. The control group was a blank wet wipe.

[0048] Calculation formula: removal rate (%) = (initial concentration - residual concentration) / initial concentration x 100%, The detection results are as follows:

[0049] Compared with example 1, the comparative example 5 has a removal effect close to ammonia, but the removal rate of hydrogen sulfide and trimethylamine decreases by about 8-9 percentage points, which shows that tea polyphenols and bamboo leaf extract have a synergistic effect. The deodorization effect of comparative example 6 decreases due to uneven distribution of active ingredients.

[0050] (5) Safety evaluation Acute oral toxicity test: Detection standard: GB 15193.3-2014 Acute Toxicity Test.

[0051] Kunming mice, half male and half female, 10 in each group, were orally administered with the immersion liquid, the maximum dose was 15000 mg / kg body weight, and the survival of the animals and the body weight change were recorded for 14 days, and the LD 50 value was calculated.

[0052] Toxicity classification standard: LD 50 >15000 mg / kg is actually non-toxic.

[0053] Skin irritation test: Detection standard: GB / T 16886.10-2017 Biological Evaluation of Medical Devices Part 10: Irritation and Delayed Hypersensitivity Reaction Test Test method: After the New Zealand white rabbits were depilated on the back, the wet wipe sample was applied for 4 h, and after removal, the skin reaction was observed for 24 h, 48 h and 72 h, and the erythema and edema scores were recorded.

[0054] The detection results are as follows:

[0055] LD of Comparative Example 2 50 only 8520 mg / kg, and with mild skin irritation, not suitable for pets to lick. All plant-based formulas have no skin irritation or only very slight irritation, suitable for sensitive skin.

[0056] (6) Stability test Accelerated stability test: Test method: The impregnation liquid sample was stored at 40℃±2℃ and relative humidity of 75%±5% for 6 months, and the active ingredient retention rate was determined by periodically sampling. The content of the main plant active ingredient was determined by HPLC method and compared with the initial content.

[0057] Active retention rate calculation: retention rate (%) = (content after storage / initial content) x 100% Phase separation observation: Test method: The impregnation liquid sample was stored at 25℃ and 40℃ respectively, and whether stratification, precipitation, turbidity and other phenomena occurred was observed regularly, and the observation time points were recorded.

[0058] The test results are as follows:

[0059] Comparative Example 6 had a significant decrease in stability, with a 6-month retention rate of only 78.2%, and stratification occurred at 3 months, proving that the preparation method had a key impact on stability. Although the other comparative examples had different degrees of defects, their stability basically met the requirements.

[0060] (7) Particle size distribution determination Detection instrument: Laser particle size analyzer (Malvern Mastersizer 3000) Test method: Take the impregnation liquid sample, dilute it with deionized water to the appropriate concentration, and after ultrasonic dispersion for 5 min, add it to the measuring pool to determine the particle size distribution. Record D 50 , D 90 and polydispersity index (PDI).

[0061] The test results are as follows:

[0062] Comparative Example 6 (simple mixing process) had a significantly larger particle size, with a PDI of 0.58, and uneven particle size distribution, which was the main reason for its poor stability. The particle size distribution of the other comparative examples was close to that of the examples, proving the effectiveness of the high-pressure homogenization process.

[0063] (8) Liquid absorption performance test Liquid absorption speed determination: Test method: 1 mL of the immersion liquid was dropped on the surface of the substrate (5 cm x 5 cm) using the drop method, and the time required for complete absorption of the liquid was recorded using a stopwatch. Each sample was measured 5 times, and the average value was taken.

[0064] Liquid holding capacity measurement: Test method: The dry substrate (10 cm x 10 cm) was weighed (W1), immersed in the immersion liquid for 45 s, removed, drained of excess liquid, and weighed again (W2).

[0065] Calculation formula: Liquid holding rate = (W2-W1) / W1 The test results are as follows:

[0066] The liquid absorption speed of Comparative Example 7 was significantly slower, with a liquid holding rate of only 2.58, and the improvement was very small, proving the necessity of plasma treatment. Plasma treatment significantly improved the liquid absorption performance and uniform distribution of active ingredients by increasing the hydrophilicity and roughness of the substrate surface.
