Abstract
Description
Technical Field
[0001] This application relates to the field of anti-fog technology for mirror surfaces, and more specifically, to an anti-fog liquid for mirror surfaces and its preparation and application methods. Background Technology
[0002] During the use of medical endoscopes, the temperature difference between the inside and outside of the body causes the endoscope surface to fog up, adversely affecting the examination. To solve this problem, medical iodine, medical alcohol, and hot water are currently used to treat the endoscope surface to achieve an anti-fogging effect. Relatively speaking, medical iodine provides the best anti-fogging effect for the longest time, but because medical iodine is purplish-black, it can easily affect light transmittance, ultimately affecting the examination results. Medical alcohol is somewhat irritating, and hot water can easily cause burns; therefore, all of these pose certain risks.
[0003] Therefore, a safe, mild, non-irritating anti-fogging liquid with a long-lasting anti-fogging effect has significant market value. Summary of the Invention
[0004] In order to solve the technical problem of how to extend the anti-fogging time of anti-fogging liquid and avoid irritating the human body, this application provides a mirror anti-fogging liquid and its preparation method and usage method.
[0005] Firstly, this application provides the following technical solution:
[0006] A mirror anti-fog liquid, comprising the following components in weight percentage:
[0007] Anhydrous ethanol 1-25%;
[0008] Ethylene glycol 2-25%;
[0009] Sodium hyaluronate 0.04-6%;
[0010] Surfactant 2.5-50%;
[0011] The remaining volume is purified water;
[0012] The surfactant comprises at least four of the following: polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, poloxamer, decyl glucoside, tocopherol glucoside, and glucosamine.
[0013] In this application, purified water and anhydrous ethanol are used as solvents, and at least four of the following surfactants are used in combination: polyether modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, poloxamer, decyl glucoside, tocopherol glucoside, and glucosamine. These surfactants are all relatively mild and have high safety.
[0014] Among them, polyether-modified silicone oil is an organosilicon nonionic surfactant, which is made by graft copolymerization of polyether and dimethylsiloxane. It has certain effects of reducing internal friction and defoaming. Lauryl glucoside not only has low surface tension, but also no cloud point and good biodegradability. Polyvinylpyrrolidone is a nonionic surfactant, and its appropriate addition can achieve good balanced dispersion and coagulation effects. Poloxamer is a nonionic surfactant with good safety performance. Decyl glucoside is a nonionic surfactant with good stability and no toxic side effects. Tocopherol glucoside and glucosamine glucan work together to achieve a good film-forming effect.
[0015] At least four of the seven components mentioned above, when used in combination, can achieve a significantly better effect than using any one component alone in equal amounts. This results in a better anti-fogging effect on the mirror and also extends the duration of the anti-fogging effect, allowing more time for endoscopic examinations.
[0016] Furthermore, the mass percentage content of the components in the anti-fog liquid for mirror surfaces is as follows:
[0017] Anhydrous ethanol 16-20%;
[0018] Ethylene glycol 2-6.5%;
[0019] Surfactant 15.5-35%;
[0020] Sodium hyaluronate 4-6%;
[0021] The remainder is purified water.
[0022] By adopting the above technical solution and further adjusting the amount of components used, the effect and service life of the obtained anti-fog liquid are improved.
[0023] Furthermore, the surfactant is composed of polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer.
[0024] The surfactants used in this application, when selected in combination with polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer, exhibit a more prominent anti-fogging effect on the mirror, and the anti-fogging duration is longer compared to combinations of other components.
[0025] Furthermore, the mass percentages of polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer in the surfactant are as follows:
[0026] Polyether-modified silicone oil 1-20%;
[0027] Lauryl glucoside 0.5-10%;
[0028] Polyvinylpyrrolidone 0.5-10%;
[0029] Poloxamer 0.5-10%.
[0030] Furthermore, the mass percentages of polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer in the surfactant are as follows:
[0031] Polyether-modified silicone oil 5.5-15.8%;
[0032] Lauryl glucoside 3.5-7.6%;
[0033] Polyvinylpyrrolidone 3.5-7.9%;
[0034] Polosham 3-6.7%.
[0035] Furthermore, the mass percentage ratio of polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer in the surfactant is 2-3.5:2-2.2:1.5-1.8:1.
[0036] In this application, the polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer, when used in different percentages, achieve different effects. Relatively speaking, the best results are achieved within the following ratio: polyether-modified silicone oil 5.5-15.8%; lauryl glucoside 3.5-7.6%; polyvinylpyrrolidone 3.5-7.9%; and poloxamer 3-6.7%. Further adjustments to the component ratios within this range further enhance the anti-fogging effect and its duration.
[0037] Secondly, this application provides a method for preparing a mirror anti-fog liquid, the specific technical solution of which is as follows:
[0038] A method for preparing a mirror anti-fog liquid, comprising the following steps:
[0039] Step 1: Thoroughly mix anhydrous ethanol, ethylene glycol, sodium hyaluronate, and purified water to obtain a first mixture. Step 2: Thoroughly mix the surfactants polyvinylpyrrolidone and poloxamer with the first mixture, then add polyether-modified silicone oil and lauryl glucoside in sequence and mix thoroughly to obtain a mirror anti-fog liquid.
[0040] In step one, when mixing anhydrous ethanol, ethylene glycol, sodium hyaluronate, and purified water, a faster mixing speed can be used. However, in step two, the mixing speed should be slightly slower to improve the uniformity of the mixture.
[0041] Furthermore, the mixing speed in steps one and two is 30-60 rpm; in step two, polyvinylpyrrolidone, poloxamer and the first mixture are mixed until there are no particulate matter, and then polyether modified silicone oil and lauryl glucoside are added in sequence and mixed.
[0042] The polyvinylpyrrolidone and poloxamer used in this application are granular substances. During the mixing process, the two substances are mixed first at a low speed to avoid excessive foaming. Then, polyether-modified silicone oil and lauryl glucoside are added to ensure thorough mixing of the components.
[0043] Furthermore, it includes the following steps:
[0044] Step A: Pour the anti-fog liquid onto the carrier and allow the carrier to fully absorb it;
[0045] Step B: Use a carrier wipe that has absorbed anti-fog liquid to wipe the mirror surface in the same direction. The wiping process should be such that the mirror surface is moistened but no foam appears. Let it stand for 4-5 minutes.
[0046] Step C: Wipe the mirror surface again with a clean carrier.
[0047] The carrier is a high-density microfiber lens cleaning cloth.
[0048] In this application, a high-density microfiber lens cleaning cloth is used as a carrier, which can achieve a better absorption effect of anti-fog liquid. Moreover, its soft texture allows the anti-fog liquid to be evenly coated on the lens surface during the wiping process.
[0049] Furthermore, the high-density microfiber lens cleaning cloth that absorbs anti-fog liquid is less likely to leave obvious wiping marks when wiping the mirror. Wiping in the same direction and being as gentle as possible reduces the possibility of foaming and makes the coating more even.
[0050] Before wiping the mirror with a carrier that has absorbed the anti-fog liquid in step B, you can also use a high-density microfiber cleaning cloth to wipe the mirror to reduce the interference of other impurities on the mirror surface with the cleaning anti-fog liquid.
[0051] Furthermore, the mass ratio of the anti-fog liquid to the carrier is 0.35 to 1.2:1.
[0052] The carrier within the above-mentioned ratio range can absorb the anti-fog liquid more fully and is less likely to drip out. When wiping the mirror surface, it can coat the anti-fog liquid more evenly on the mirror surface more quickly, and the drying time is also shorter, which provides convenience for rapid inspection.
[0053] In summary, this application has the following beneficial effects:
[0054] 1. The surfactants in this application, including polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, poloxamer, decyl glucoside, tocopherol glucoside, and glucosamine, are safe, mild, and non-irritating. They work together with sodium hyaluronate to achieve a smaller water contact angle and a longer anti-fogging time for the obtained mirror anti-fog liquid.
[0055] 2. The surfactant in this application, composed of polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer, works in conjunction with sodium hyaluronate to form a mirror-finish antifog liquid with a smaller water contact angle and a longer antifog duration.
[0056] 3. In this application, by adjusting the amount of surfactant and the amounts of polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer, the anti-fogging effect of the mirror anti-fog liquid is further improved and the water contact angle is reduced.

[0090] Characterization experiment
[0091] 1. Anti-fog effect test
[0092] Test subjects and test methods:
[0093] Under constant temperature and humidity conditions of 25℃ room temperature and 55% relative humidity, turn on the water bath and set the water temperature in the water bath to 37.5℃.
[0094] The methods described in Examples 25-48 and Comparative Examples 6-10 were used, wherein the mirror surface was replaced by the unpolished side of a glass slide, and the slide had been placed under the aforementioned indoor environmental conditions for 2 hours to fully acclimatize to the environment. Each method of use corresponds to 6 glass slides, which were used to observe whether fogging occurred on the slides at time points of 60 min, 120 min, 180 min, 240 min, 300 min, and 360 min, respectively.
[0095] After processing according to the methods described in Examples 25-48 and Comparative Examples 6-10, the corresponding slides were immediately moved directly above the observation hole of the water bath, so that the water vapor was facing the side of the slide that had been wiped with the anti-fog solution. The slides were then observed to see if they fogged up and whether the marked points were still clearly visible. The marked points were the 30cm visual acuity chart used in hospitals behind the slides. The time it took for the slides to fog up was recorded and analyzed.
[0096] Test results: The anti-fog effect achieved by using the methods described in Examples 25-48 and Comparative Examples 6-10, i.e., using the anti-fog liquids in Examples 1-24 and Comparative Examples 1-5, is shown in Table 5.
[0097] Table 5 shows the anti-fog effects achieved using the anti-fog liquids in Examples 1-24 and Comparative Examples 1-5.
[0098]
[0099] In this application, the pH value of the anti-fog liquid used in Examples 1-24 is measured to be 3.5-7.0.
[0100] As shown in Table 5, in this application, by using Examples 1-24 and in conjunction with the processing method described in this application, the unsanded side of the glass slide can achieve a better anti-fog effect.
[0101] When using Examples 1, 5, and 12, the time to start fogging is shorter compared to other examples. This phenomenon may be related to the smaller amount of the four surfactants used.
[0102] When using Examples 2-4, the anti-fogging time is longer compared to that of Examples 1, 5, and 12. This phenomenon may be due to the fact that the total amount of the four surfactants used in these examples is greater.
[0103] When using Examples 6 and 13, the anti-fogging time is longer compared to other examples; and comparing the anti-fogging effect achieved by Examples 6 and 13, Example 6 is more effective. This is because, on the one hand, the total amount of the four surfactants used in Examples 6 and 13 is larger; on the other hand, the amounts and compatibility of the polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer used in Example 6 are more reasonable.
[0104] When using Examples 7-9, the anti-fogging effect is better than that of Example 2. This is likely due to two main reasons: firstly, the total amount of the four surfactants used is larger; secondly, the amounts and compatibility of the polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer are more reasonable. However, Examples 7 and 8 achieve similar anti-fogging effects, further demonstrating that a reasonable combination of the amounts of polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer can achieve better anti-fogging results.
[0105] Compared with the use of Examples 10-11 and Examples 6 and 13, the anti-fogging effect achieved is similar, which also indicates that the ratio of polyether modified silicone oil, lauryl glucoside, polyvinylpyrrolidone and poloxamer has a significant impact on the anti-fogging effect.
[0106] Compared with Example 25, Examples 38-39 show that the anti-fogging effect is quite similar. The main reason for this phenomenon is that the rotation speed during the preparation process is within a reasonable range in this application and has little impact on the anti-fogging effect of the final mirror anti-fogging liquid. The order of addition of the components in the anti-fogging liquid and the mixing time also have little impact, as long as all components are fully mixed.
[0107] Compared to Examples 42 and 43, Examples 42 and 43 provide a longer anti-fogging time; Example 44 achieves an even longer anti-fogging time than Examples 42 and 43. This phenomenon may be due to the fact that Example 18 used decyl glucoside and tocopherol glucoside, and Example 19 used decyl glucoside and glucosamine. Under the same dosage, the longer anti-fogging time is achieved by combining decyl glucoside, tocopherol glucoside, and glucosamine with polyether-modified silicone oil, lauryl glucoside, polyvinylpyrrolidone, and poloxamer.
[0108] The amount of surfactant used in Examples 21-24 was the same as that in Example 1. However, compared to Examples 23 and 24, Examples 47 and 48 showed a longer antifogging time, indicating that the surfactants in this application have a good compounding effect. Looking at Examples 21 and 22 together, although the number of components used was greater than in Example 1, the final antifogging time was slightly lower than that of Example 1, indicating that the selection of specific components in the surfactant is crucial.
[0109] Compared with Example 25, Examples 49-50 show that when the mass ratio of anti-fog liquid to carrier is within a reasonable range, uneven or excessive application is less likely to occur when wiping the mirror surface, thus having a minimal impact on the anti-fog effect. Furthermore, wiping the mirror surface with a clean, high-density microfiber lens cloth before applying the anti-fog liquid can remove impurities from the mirror surface, but this has little overall impact on the anti-fog effect.
[0110] 2. Water contact angle test
[0111] Test subjects and test methods:
[0112] Under constant temperature and humidity conditions of 25°C and 55% indoor environment, the slide was placed in this indoor environment for 2 hours to fully adapt to the environmental conditions.
[0113] Three glass slides were prepared for each test subject. All three slides used the same test subject and were processed according to the procedures described in Examples 25-48 and Comparative Examples 6-10. The resulting processed slides were then placed on each of the three slides, and the water contact angles on each slide were measured. The average angles were then recorded and analyzed. This process was repeated for each test subject.
[0114] Test results: The water contact angles on the glass slides after treatment using the methods described in Examples 25-48 are shown in Table 6.
[0115] Table 6. Water contact angles on glass slides treated according to the usage methods of Examples 25-48.
[0116]
[0117] According to Table 6, the examples achieve a smaller water contact angle compared to the comparative examples, indicating that the anti-fog liquid in this application achieves better hydrophilicity. Combining Tables 5 and 6, while Comparative Example 1 also provides a longer anti-fog time, this application still offers many superior anti-fog liquids (examples); the water contact angle is larger when using Comparative Example 1 compared to the examples. Therefore, considering both anti-fog duration and water contact angle, the examples demonstrate better performance and represent a greater improvement over Comparative Example 1.
[0118] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
