Description

Technical Field

[0001] This invention relates to the field of cleaning agents, and more specifically to a cleaning agent suitable for surfaces of various materials, particularly a cleaning agent for terminal counter facilities. Background Technology

[0002] Currently, both domestic and international airlines and airports generally suffer from poor counter cleaning conditions. All airport counters are cleaned by the airport group's property management company, and there are no clear cleaning standards or regulations for airport counters, either domestically or internationally. Furthermore, domestic and international airlines do not emphasize counter cleaning during ground service staff training. Therefore, there is a significant blind spot in counter cleaning for both airports and airlines; neither recognizes the impact of environmental cleanliness on passengers or its importance to airlines. Compared to the cleanliness of high-speed rail stations, the dirt and stickers on airport check-in counters can easily make passengers uncomfortable and affect the aesthetics. Therefore, the issue of counter cleaning urgently needs to be addressed.

[0003] Airport property management is generally responsible for the professional cleaning of check-in counters, information counters, transfer counters, and boarding counters in the terminal. However, during peak flight periods, the counters are used frequently, resulting in a lot of residue such as adhesive, stickers, and dirt. Cleaning staff cannot handle this in a timely manner to keep the counters clean. In addition, the cleaning process requires the use of different types of cleaning agents for different materials such as metal, granite, wood, rubber, and resin, making the operation complicated, tedious, and inefficient.

[0004] Patent CN201911307633.6 discloses an adhesive remover and its preparation method. The formula of this invention mainly uses D-limonene as the adhesive remover, and is equipped with kerosene, alcohols, ethers and other additives. Among them, kerosene and alcohols are flammable and explosive reagents, which are dangerous and have low cleaning efficiency. They can only be used for adhesive removal and are not effective for cleaning old dirt, stubborn stains, disinfectant gels, oil stains, etc., nor do they have a polishing function. Summary of the Invention

The concentrate may be formulated without any water, or may be provided with a relatively small amount of water to reduce the cost of transporting the concentrate. For example, in the form of compressed powder, capsules of solid or loose powder, or beads encapsulated in soluble material. For the purposes of this disclosure, the terms "capsule" and "bead" are used for illustrative purposes and are not intended to limit the specific shape or form of transport of the invention. In some embodiments, the cleaning agents of the present invention are provided in solid form, which dissolves and solubilizes upon contact with a solvent, or otherwise disintegrates, thereby allowing the cleaning agent to become a usable cleaning agent for further application to the surface to be cleaned.

[0128] Therefore, in some embodiments, the present invention also provides the use of the cleaning agent as described in any embodiment herein in cleaning products, particularly in the cleaning of various material surfaces.

[0129] In this article, the cleaning and staining rate is measured by the removal rate of 50 g of oil stains by 40 mL of cleaning agent, and the amount of cleaning agent used for thorough cleaning is the amount of cleaning agent used when the cleaning and staining rate is 100%.

[0133] The present invention will be further described below by way of specific embodiments. It should be understood that these embodiments are merely illustrative and not intended to limit the scope of the invention. The methods and reagents used in the embodiments are conventional methods and reagents in the art, unless otherwise stated. In this document, sodium hexadecyl sulfonate (CAS No.: 15015-81-3) was purchased from BASF (China) Co., Ltd., nonylphenol polyoxyethylene ether NP-40 was purchased from BASF (China) Co., Ltd., and the adhesive remover D-limonene was purchased from Yisenyuan Plant Fragrance Co., Ltd.

[0134] Cleanliness and dirtiness ratio calculation method

[0135] Mix petroleum jelly, dust, animal fat, and vegetable oil in a 1:1:3:3 ratio. Take 50 g of the mixture and apply it evenly to a 20 mm thick layer of soil. Test pieces of the same size made of 100mm metal, glass, and PVK / PVC / PU materials were left to stand for 7 days to simulate years of accumulated dirt. Disinfectant gel and dust were mixed in a 3:1 ratio, and 50g of each mixture was evenly applied to 20mm thick test pieces. On a 100mm metal surface and on test pieces of the same size made of PVK / PVC / PU material, the samples were left to stand for 48 hours to simulate the residue of disinfectant gel.

[0136] Spray 40 mL of cleaning agent onto the dirt and gel residue. Wipe the stained area back and forth 10 times evenly and with the same pressure using a cleaning cloth, and observe the degree of cleaning. Divide the cleaned area by the total coated area to obtain the removal rate.

[0137] The amount of cleaning agent used to thoroughly clean dirt is the amount of cleaning agent used when the dirt level is 100%.

[0138] Surface tension measurement and calculation of cleaning agents

[0139] The measurement is primarily performed using a surface tension meter, based on the ring method. A metal ring (made of platinum wire) immersed in the cleaning agent solution is detached from the liquid. The maximum pulling force F required is equal to the weight G of the ring itself plus the product of the surface tension F0 and the circumference L of the detached surface. The ambient temperature is maintained at approximately 25°C during the measurement.

[0140] Permeation time measurement

[0141] The canvas settling method was used. A circular canvas with a diameter of 30 mm was used as the test material. Each canvas was placed on the surface of the liquid to be tested, and the time from when the canvas was placed on the liquid to when it completely settled to the bottom of the liquid was recorded. The shorter the time, the stronger the permeability.

[0238] Table 4. Formulations and properties of Comparative Examples 16-28

[0239]

[0240] Table 1 shows that the cleaning agent of the present invention significantly improves the stain removal rate, with Example 3 showing the highest improvement. Specifically, the optimal ratio of sodium hexadecyl sulfonate / NP-40 / D-limonene is 1:3:3.5, resulting in the highest cleaning rate, lowest surface tension, and highest surface activity, demonstrating the strongest synergistic effect among the three components. Table 2 shows that after removing sodium hexadecyl sulfonate, nonylphenol polyoxyethylene ether, and D-limonene, the cleaning agent significantly reduces the cleaning rate on metal, glass, and rubber surfaces, indicating that these components play a crucial role in cleaning multi-material surfaces such as airport check-in counters. Tables 3-4 show that while existing cleaning agents exhibit good cleaning performance on some materials, they cannot meet the comprehensive cleaning needs of multiple materials.
