Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of personal care products, in particular to a composite cleaning, deodorizing and antioxidant care wet wipe for the elderly and a preparation method thereof. BACKGROUND

[0002] With the gradual improvement of living standards, the demand for cleaning, skin care and deodorization of the elderly who have difficulty taking a bath and the long-term bedridden population will continue to grow.

[0003] The traditional bathing method is mainly to use a towel to wipe, which has the following significant pain points: the friction is large, which can easily cause abrasion to the fragile skin of the elderly, and the repeated use of the towel can easily breed bacteria and produce odor, resulting in incomplete cleaning. In addition, from the market point of view, existing wet wipes are more focused on baby wet wipes and ordinary adult wet wipes, and there are few wet wipes for the elderly that have cleaning, skin care and deodorization functions. The few wet wipes on the market for the care of the elderly are not much different from ordinary sanitary wipes, mainly promoting sterilization and ordinary cleaning functions, without deodorization and skin care functions.

[0004] In 2001, Japanese scholars published a study in the Journal of Investigative Dermatology, which found that 2-nonene aldehyde could be detected on the surface of the skin of people over 40 years old, and its concentration increased with age. This substance is produced by the oxidative degradation of omega-7 unsaturated fatty acids, has a greasy and grassy odor, and is the main chemical component of the odor of the elderly. Mechanism: aging leads to a decrease in the skin's antioxidant capacity (such as a decrease in tocopherol (vitamin E)), and hormonal changes promote an increase in omega-7 fatty acids in sebum, which are oxidized to form 2-nonene aldehyde and accumulate in wrinkles.

[0005] Most of the wet wipes on the market are designed for infants or ordinary adults, and their functions are mainly focused on basic cleaning and sterilization. A few care wet wipes for the elderly also often only focus on cleaning or basic moisturizing, which have the following shortcomings: 1) The product does not contain moisturizing ingredients, which can cause a large amount of friction during cleaning and easily damage the fragile skin barrier of the elderly; 2) The deodorizing method is mainly to use fragrances to cover up or simply sterilize, which has potential irritant risks to the skin; 3) Lack of targeted removal technology for 2-nonene aldehyde; 4) Ignoring skin antioxidant, which cannot reduce the generation of odor from the root.

[0006] Therefore, there is an urgent need in the art to develop a special care wet wipe for the elderly that can meet the multiple needs of gentle cleaning, targeted deodorization, deep moisturizing and effective antioxidant. SUMMARY

[0007] The present application aims to overcome the deficiencies in the prior art, and provide a composite cleaning, odor-removing and antioxidant care wet wipe for the elderly and a preparation method thereof, which can gently clean the skin and achieve the comprehensive care effect of targeted odor removal, nourishment and moisture retention and antioxidant through the synergistic effect of specific active ingredients.

[0008] The present application is realized by the following technical solutions: on the one hand, a composite cleaning, odor-removing and antioxidant care wet wipe for the elderly is provided, which comprises a substrate and a care liquid loaded thereon, and the raw materials of the care liquid include cleaning components, odor-removing components, skin care and moisture retention components, antioxidant components, preservative components and solvents. The odor-removing components are any component or combination of cyclodextrin and aminotrizole. The antioxidant components are any component or combination of pine nut oil and tocopherol.

[0009] Through the above technical solutions, cyclodextrin can effectively embed and capture 2-nonenal molecules like a "molecular pocket" based on its unique ring cavity structure, and then realize the targeted adsorption and neutralization of the key molecule 2-nonenal of "old man smell"; aminotrizole can neutralize and decompose low fatty acid odor molecules, and the two components synergistically remove odor from the source, rather than simply masking with fragrance, so that the odor-removing effect is thorough and long-lasting, avoiding the embarrassment and irritation of fragrance masking, and further realizing the root odor removal.

[0010] Further, the raw materials of the care liquid include 0.5%-5% cleaning components, 2.6%-4% odor-removing components, 4%-10% skin care and moisture retention components, 1%-4% antioxidant components, 0.1%-1.5% preservative components, and the balance is solvent.

[0011] Further, the odor-removing components are cyclodextrin and aminotrizole, and the mass ratio is 2.6-4:1.

[0012] Through the above technical solutions, cyclodextrin can effectively embed and capture 2-nonenal molecules like a "molecular pocket" based on its unique ring cavity structure; aminotrizole can neutralize low fatty acid odor molecules, and the two components synergistically remove odor from the source.

[0013] Specific Mechanism: The "old person's smell" is a mixture of various odor molecules, including hydrophobic aldehydes (such as the key molecule 2-nonenal) and acidic lower fatty acids. Cyclodextrin, with its hydrophobic inner cavity and hydrophilic outer edge ring-shaped conical cavity structure, selectively encapsulates and captures nonpolar aldehyde molecules such as 2-nonenal through hydrophobic interactions and van der Waals forces, forming stable inclusion complexes that physically isolate them from the skin surface. Tromethamine, as an organic amine, has amino groups that neutralize low-molecular-weight acidic odor molecules such as carboxylic acids, converting them into salts with weaker odors or non-volatile compounds. Both target odor components with different chemical properties, achieving comprehensive removal from physical adsorption to chemical transformation, exhibiting strong complementarity. The presence of tromethamine in this invention positively impacts the inclusion efficiency of cyclodextrin. Under a near-neutral, mild pH environment (maintained by the buffering effect of tromethamine), the cavity structure of cyclodextrin remains optimal, facilitating the inclusion of 2-nonenal. In addition, tromethamine preferentially neutralizes acidic substances, which may reduce the competition between these molecules and cyclodextrin for inclusion sites, indirectly increasing the inclusion capacity and rate of cyclodextrin for target aldehyde molecules.

[0014] When the mass ratio of cyclodextrin to tromethamine is within the range of 2.6-4:1, this odor-removing system not only achieves immediate and long-lasting odor removal effects, but also ensures sufficient cyclodextrin to effectively encapsulate the persistent aldehyde odor produced by sebum oxidation, while providing an appropriate amount of tromethamine to neutralize acidic substances in sweat. The two work synergistically to achieve a long-lasting odor-removing cycle from source blocking to immediate neutralization. Furthermore, this ratio avoids the sticky or dry feeling that may result from excessive cyclodextrin, and also avoids the skin irritation or impact on the pH stability of the lotion that may be caused by excessive tromethamine. This allows the product to maintain excellent skin affinity and comfort while effectively removing odor (see Comparative Example 4 data; excessive amounts lead to increased stickiness). Therefore, the components at this ratio can coexist harmoniously with the antioxidant oil phase and gentle cleansing surfactants in the formula without affecting the stability of the emulsion system; effectively constructing an innovative odor-removing solution with synergistic enhancement effects, multiple targets, and comprehensive product performance.

[0015] Furthermore, the antioxidant component is pine nut oil and tocopherol in a mass ratio of 0.6-3:1; The pine nut oil is selected from red pine (Pinus koraiensis). PINUS KORAIENSIS Seed oil or five-leaf pine ( PINUS PENTAPHYLLA One or two of the following seed oils; The tocopherol is selected from one or both of tocopherol acetate and tocopherol (vitamin E).

[0016] Furthermore, the cleaning component is one or both of sodium lauroyl oat amino acid and sodium cocamidopropyl PG-dimethylammonium chloride phosphate.

[0017] Further, the skin care and moisturizing component comprises a moisturizing agent, an emollient and an emulsifier; the mass ratio of the moisturizing agent, the emollient and the emulsifier is 4.5:5.4:0.57-0.9.

[0018] Further, the moisturizing agent is selected from one or more of trehalose, 1,3-butanediol, panthenol; the emollient is selected from any one or more of caprylic / capric triglyceride, hydrogenated polyisobutene, cetyl stearyl alcohol; the emulsifier is selected from any one or more of sorbitan stearate, polysorbate-60, PEG-100 stearate.

[0019] Further, the preservative component is selected from any one or more of phenoxyethanol, chlorphenesin, 1,2-hexanediol, raspberry ketone, p-hydroxyacetophenone, ethylhexylglycerin.

[0020] Finally, a method for preparing the above-mentioned composite cleaning, deodorizing and antioxidant care wet wipes for the elderly population is provided, which comprises the following steps: Step 1) Mix the solvent, the moisturizing agent in the skin care and moisturizing component, the deodorizing component and the thickening agent, heat to 75-80℃ and stir until dissolved uniformly to obtain an aqueous phase and transfer to a vacuum emulsifying pot; Step 2) Mix the antioxidant component, the emulsifier and the emollient in the skin care and moisturizing component, heat to 75-80℃ and stir until dissolved uniformly to obtain an oil phase; Step 3) Add the oil phase to the aqueous phase, homogenize at a speed of 2000-4000 r / min for 5-15 minutes at 75-80℃, then add the preservative component and homogenize for another 5 minutes to obtain an emulsion; Step 4) Cool the emulsion to 40-45℃, add the cleaning component and stir to mix uniformly to obtain a care solution; Step 5) Load the care solution on the substrate and package to obtain the wet wipes.

[0021] Further, in step 1), a pH regulator and a thickening agent are also added in step 1), the pH regulator is selected from one or both of citric acid and lactic acid; the thickening agent is selected from one or both of acrylate / acrylamide copolymer and hydroxyethyl cellulose; And / or, in step 4), a fragrance and a skin astringent are also added in the emulsion; the fragrance is selected from any one or more of bergamot essential oil, jasmine essential oil, rose essential oil, lavender essential oil, mint fragrance and jasmine fragrance; and / or, the skin astringent is any one or both of menthyl lactate and menthol.

[0022] Beneficial effects This invention introduces a synergistic odor removal system composed of cyclodextrin and tromethamine, which achieves the encapsulation and chemical neutralization of odor molecules, thereby achieving targeted and root-cause odor removal at the molecular level. At the same time, this invention integrates a complex antioxidant network composed of pine nut oil and tocopherol, which effectively scavenge free radicals, delay lipid peroxidation, and inhibit the formation of odor precursors from upstream.

[0023] This invention also achieves the functional coupling of cleansing, deodorizing, moisturizing and anti-oxidation in a single formulation, and ensures the gentleness of use and the safety of the skin barrier by selecting a low-allergenic component system with a pH value close to that of the skin, reflecting the modern skin care concept from symptom management to cause control.

[0083] I. Effect evaluation experiment The care liquids or wet wipes prepared in Examples 1-8 and Comparative Examples 1-8 above were subjected to performance tests under the following test conditions. 1.1 Moisturizing property detection: Test sample: composite cleaning, deodorizing and antioxidant care wet wipes for the elderly population provided in Examples 1-8 and Comparative Examples 1-8 Test instrument: Corneometer test probe manufactured by Courage + Khazaka Company (CK Company) of Germany. The capacitance of the stratum corneum before and after use was measured using the instrument to measure the change in water content in the stratum corneum.

[0084] Test method: 160 healthy people aged 20-45 years were selected and divided into 16 groups, 5 men and 5 women in each group, and one sample in each of the examples and comparative examples was tested in each group. The test site cannot use any product (cosmetic or external medicine or internal health care product) for 15 days before the test. Before the test, the subjects were required to wash their hands and forearms, enter a constant temperature and humidity room with a temperature of 21±1℃ and a humidity of 50±5%, sit for 30 minutes, and keep a relaxed state, and wipe the specified area with a wet wipe. Then draw a 3x3cm square experimental area on the left and right sides of the test area, and use the left arm as the test area of the product, and the corresponding symmetrical area on the right arm as the blank control. Then use the Corneometer test probe to detect the moisture content of each experimental site, repeat 5 times, and obtain the average value of each test, and record the data.

[0085] ​The calculation formula is: Hydration rate (%) = (test value - blank value) x 100 / blank value.

[0086] 1.2 Deodorant performance test: Test sample: composite cleaning deodorant antioxidant care wet wipes for the elderly provided by examples 1-8 and comparative examples 1-8 Test method: 80 healthy people prone to odor were selected, aged 40-70, divided into 16 groups, 3 men and 2 women in each group. In addition, 5 people with normal olfactory were selected as the evaluation team for artificial sniffing method. Before testing, the volunteers needed to have obvious odor, then each group tested one sample in examples and comparative examples, and the test sample was tested in a constant temperature and humidity environment. After 0.5h, 8h and 24h after the volunteers used the sample, the evaluation team smelled the odor on the volunteers and scored it. The score was 10 points, the higher the score, the better the deodorizing effect, and the test result was the average value of each group.

[0087] 1.3 Cleaning performance test: Physical cleaning performance evaluation Test sample: care liquid with cleaning, deodorizing and antioxidant multiple functions provided by examples 1-8 and comparative examples 1-8 Test method: 1cm 2 of colored beauty cosmetic was applied on a 1cm x 3cm size 3M breathable adhesive tape, weighed, and 1cm 2 of care liquid with cleaning, deodorizing and antioxidant multiple functions was loaded and rubbed for 2min, then the tape was rinsed with clean water and dried, weighed, and the remaining amount of colored beauty cosmetic was calculated.

[0088] Cleaning degree = ((tape weight before use - tape weight after use) / (tape weight before use - net weight of tape)) * 100%; the weight of 1cm x 3cm size 3M breathable adhesive tape was weighed as 0.8g.

[0089] 1.4 Mildness performance test: Test sample: care liquid with cleaning, deodorizing and antioxidant multiple functions provided by examples 1-8 and comparative examples 1-8 Test method: 160 volunteers aged 20-45 were selected, the test subjects were divided into 16 groups, 10 people in each group, and the same test sample was used. The test subjects cleaned both sides of the face, wiped dry, and dropped a drop of water on both sides of the alae nasi, and a certain amount of care liquid with cleaning, deodorizing and antioxidant multiple functions provided by examples and comparative examples was applied on both sides of the alae nasi of each group of volunteers, respectively. The alae nasi of each group of volunteers were rubbed and massaged for 2min, and then washed.

[0090] The test index is the scoring of skin pain, dry skin, allergy or redness, using a 10-point scale, with 0 indicating no corresponding sensation and 10 indicating very obvious sensation. The statistical data is averaged, and the larger the value, the more obvious the sensation.

[0091] 1.5 Stickiness test Test sample: composite cleansing, deodorant and antioxidant care wipes for the elderly provided by Examples 1-8 and Comparative Examples 1-8 Test method: 160 volunteers aged 20-45 were selected, and the subjects were divided into 16 groups, with 10 people in each group, using the same test sample. Before the test, the subjects were required to enter a constant temperature and humidity environment, and to wash their forearms. After natural air drying, the composite cleansing, deodorant and antioxidant care wipes for the elderly provided by Examples and Comparative Examples were used to wipe the specific areas of the left forearm of each group of volunteers, and the same areas of the left forearm were compared after wiping and air drying.

[0092] The test index is the scoring of stickiness, using a 10-point scale, with 0 indicating very obvious stickiness and 10 indicating no obvious stickiness. The statistical data is averaged, and the larger the value, the less obvious the sensation.

[0093] 1.6 Antioxidant performance test Instrument and reagent: UV-visible spectrophotometer; 95% ethanol; 1,1-diphenyl-2-trinitrobenzene hydrazine (Sigma Company): 0.12mg / ml. DPPH ethanol solution: weigh 1,1-diphenyl-2-trinitrobenzene hydrazine 12mg in a 250mL beaker, add 100ml 95% ethanol, stir with a glass rod until dissolved, and obtain; Positive control: tocopherol (vitamin E), purity ≥96%.

[0094] Test sample: care liquid with cleaning, deodorant and antioxidant multiple functions provided by Examples 1-8 and Comparative Examples 1-8 Experimental method: the positive control was dissolved and diluted with 95% ethanol to a series of concentration gradients of 0.08mg / ml., 0.04mg / ml., 0.02mg / mL., 0.01mg / ml. to verify the test system.

[0095] Subject treatment: water-soluble subjects were diluted with water to multiple concentration samples, and oil-soluble subjects were diluted with 95% ethanol to multiple concentration samples.

[0096] Referring to Table 1, 10ml test tubes were used to set up sample tubes (T), sample background (To), DPPH tubes (C) and solvent background (Co). For each test concentration of each sample, 3 parallel tubes of sample tubes (T) were set up, and 3 parallel tubes of DPPH tubes (C) were also set up.

[0097] In the sample tube (T) and the sample background (To), 1ml of the same concentration of sample solution was added. In all test tubes (T, To, C, Co), the solvent was supplemented, water-soluble samples with water, and oil-soluble samples with 95% ethanol, supplemented to 3ml, and mixed. In the sample tube (T) and the DPPH tube (C), 1ml of DPPH ethanol solution was added, and the sample background (To) and the solvent background (C%) were replaced with 95% ethanol, and gently shaken and left at room temperature for 5 minutes. Each reaction solution was moved into a 1cm cuvette, and the absorbance value was measured at 517nm.

[0098] The DPPH free radical scavenging rate was calculated: scavenging rate (%) = 【1- (T-To) / (C-Co) 】x100% In the formula: T is the sample tube absorbance value, i.e. the absorbance value of the solution after the sample reacts with DPPH; To is the sample background absorbance value; C is the DPPH tube absorbance value, which is the average of three times, i.e. the absorbance value of the DPPH solution without adding the sample: Co is the solvent background absorbance value.

[0099] II. The detection results are shown in the following table:

[0100] In summary, the embodiments 1-8 of the present application all show excellent and balanced comprehensive performance in terms of moisturizing, deodorizing, cleaning, mildness and antioxidant properties; the designed comparative examples 1-8 are used to verify the influence of different components or ratios deviating from the preferred range of the present application, and the results further highlight the necessity and synergistic advantages of the technical scheme of the present application: In the comparative example 1, the cyclodextrin is missing, resulting in a significant decrease in deodorizing and antioxidant properties, which confirms the indispensable role of cyclodextrin in embedding aldehyde odor molecules and assisting in antioxidant properties.

[0101] In the comparative example 2, no tocopherol is added, resulting in a significant decrease in DPPH scavenging rate, which indicates that the complex antioxidant system composed of pine nut oil and tocopherol has a synergistic effect, which can more effectively scavenge free radicals and inhibit the oxidation of sebum.

[0102] In the comparative example 3, the sodium cocamidopropyl PG-dimethyl ammonium phosphate is replaced by sodium lauryl sulfate, causing dry skin and redness, which proves that the surfactant system selected in the present application significantly improves the mildness and barrier protection function while ensuring the cleaning force.

[0103] The excess of tromethamine in Comparative Example 4, although the short-term deodorization score is improved, the cleaning rate is decreased and the sticky feeling is enhanced, indicating that the deodorization components need to be strictly controlled in the preferred ratio (cyclodextrin: tromethamine = 2.6-4:1) range, so as to realize the balance of efficacy and skin feeling.

[0104] In Comparative Example 5, the amount of cleaning component is doubled, although the cleaning power is improved, but the moisturizing and antioxidant performance is decreased, and the sticky feeling is increased, indicating that the content of the cleaning component in the present application has been optimized to the best interval considering the cleaning efficiency and the overall system stability.

[0105] In Comparative Example 6, the cyclodextrin is excessive, which leads to a decrease in long-term deodorization effect and a sticky skin feeling, further confirming the importance of the deodorization component ratio, which will affect the overall performance balance if it exceeds the preferred range.

[0106] In Comparative Example 7, the proportion of tocopherol is too high and the proportion of pine nut oil is too low, resulting in a decrease in DPPH clearance rate and cleaning performance, indicating that pine nut oil and tocopherol can only exert the best synergistic antioxidant effect in the mass ratio range of 0.6-3:1.

[0107] In Comparative Example 8, the deodorization components are excessive, although the short-term deodorization effect is significant, but the cleaning rate is greatly reduced and the sticky feeling is obvious, indicating that the components need to work synergistically in the preferred ratio range described in the present application, in order to achieve the comprehensive care effect of multiple functions.

[0108] Therefore, the present application constructs a care system with multiple functions of cleaning, deodorization, moisturizing and antioxidant by the embedding-neutralization deodorization mechanism of cyclodextrin and tromethamine, the antioxidant network of pine nut oil and tocopherol, the mild and effective surface active cleaning system, and the overall balance of each component in the preferred ratio.
