Quaternary ammonium salt disinfectant is a new type of disinfectant that has received widespread attention and application in recent years due to its high efficiency, safety, low toxicity, and environmental protection characteristics. With the continuous improvement of people's awareness of health and environmental protection, the market prospects of quaternary ammonium salt disinfectants are also becoming increasingly broad. Firstly, with the continuous intensification of the global epidemic, the demand for disinfectants is constantly increasing. The efficient bactericidal ability of quaternary ammonium salt disinfectants has made them an important disinfectant in industries such as hospitals, laboratories, and food processing. Meanwhile, with the increasing demand for disinfectants in people's daily lives, quaternary ammonium salt disinfectants will gradually enter thousands of households. Secondly, with the continuous improvement of people's awareness of environmental protection and health, the requirements for the safety and environmental friendliness of disinfectants are also increasing. The low toxicity and environmental friendliness of quaternary ammonium salt disinfectants have made them increasingly popular as environmentally friendly disinfectants. At the same time, as the government's support for the environmental protection industry continues to increase, the market prospects of quaternary ammonium salt disinfectants will also become increasingly broad. Finally, with the continuous progress and innovation of technology, the application fields of quaternary ammonium salt disinfectants are also expanding. For example, quaternary ammonium salt disinfectants can be used for disinfection of medical devices, sanitary ware, surface environments, and other aspects, and can be applied in more fields in the future. In summary, the market prospects of quaternary ammonium salt disinfectants are very broad.   Ahsuperchem supply Didecyl dimethyl ammonium chloride (DDAC) and Benzalkonium chloride (BKC), which are widely used as the raw materials for disinfectants.

The air conditioner in an operating room is a source of air pollution, and it is necessary to regularly clean or disinfect the air conditioner filters to control the air pollution source. In the past, the air conditioner filters in our hospital's operating rooms were mostly cleaned using the method of flowing water scrubbing, which could not effectively control the bacterial count, resulting in a low hygiene qualification rate. To improve the cleaning and disinfection effectiveness of air conditioner filters, we adopted a method of scrubbing followed by disinfectant spray using a long-chain quaternary ammonium salt, and achieved good results. The disinfectant used contained 1000 mg/L of long-chain quaternary ammonium salt, and its actual disinfection effect was tested. The results are reported as follows: 1. Method:Sixty air conditioner filters were selected and divided into an experimental group and a control group, with 30 filters in each group. Before cleaning and disinfection, sterile cotton swabs were used to sample the area of 5cm×5cm on the air conditioner filters by uniformly wiping back and forth 5 times with sampling fluid. This served as the positive control before disinfection. In the experimental group, the air conditioner filters were first cleaned with flowing water, and then dried with sterile wipes. On this basis, the filters were then sprayed with a disinfectant containing 1000 mg/L of long-chain quaternary ammonium salt for 3-5 minutes before sampling. In the control group, the filters were cleaned with flowing water, dried with sterile wipes, and immediately sampled after cleaning. The sampling method was the same as the pre-disinfection sampling. The sterile cotton swab heads used for sampling were cut into test tubes containing 10 ml of sterile elution solution with the corresponding neutralizer, thoroughly shaken for elution, and the elution solution was used for viable bacterial count culture to calculate the total number of viable bacteria. The evaluation criteria for the results were based on the standard GB15982-1995 "Hygienic Standard for Hospital Disinfection." Qualified results were defined as having a total bacterial count of no more than 5 colonies/cm2 on the surface of objects in Class II areas, and the absence of pathogenic bacteria. 2. Results:The results of the tests showed that after the filters in the experimental group were cleaned with flowing water and then sprayed with the disinfectant containing 1000 mg/L of benzalkonium chloride and chlorhexidine, the total bacterial count on the surface of the air conditioner filters was reduced to <1.0 cfu/cm2 after a 5-minute action time. The disinfection qualification rate was 100%. In the control group, although cleaning the air conditioner filters with water alone reduced the number of contaminated bacteria to some extent, the hygiene qualification rate was only 30%. Comparison of two methods for cleaning and disinfecting air conditioning filter screens: Group Number of detections Number of bacteria before cleaning( cfu /cm 2 )  Number of viable bacteria after cleaning( cfu /cm 2 )  Qualified copies Pass rate(%) Control group 30 28.24 ±8.26  7.46 ±3.17 9 30.0 Test group 30 28.24 ±8.26  0.35 ±0.39 30 100.0 Therefore, we believe that the approach of regular cleaning followed by disinfectant spray using long-chain quaternary ammonium salt can meet the hygiene quality requirements for air conditioner filters in operating rooms. It is recommended to clean and disinfect them once a week and enhance the cleanliness and hygiene management during the use of the air conditioner to prevent an elevation of indoor microbial counts.
