In the field of disinfectants, chlorine dioxide, as an A1 level safe disinfectant recognized by the World Health Organization (WHO), occupies a dominant position from drinking water treatment to food processing and packaging, from production sources to end shelves, with its stable and reliable irreplaceable disinfection advantages.

In exploring the development pattern of foreign countries, North America and Europe, relying on strict regulations and upgrading requirements of authoritative standards such as EPA (Environmental Protection Agency), no longer regard disinfection as the end link, but embed it into the vascular system of the production process, which well demonstrates the legitimacy and effectiveness of its disinfection effect. In the Asian region, which was introduced later, the market share of chlorine dioxide in 2024 alone has already accounted for about 36% of the global market, which is sufficient to prove its important position in the market.

1、 Assist in the high-quality development of the food industry

Against the backdrop of global food consumption demand upgrading towards healthiness, chlorine dioxide, compared to traditional chlorine based disinfectants, can completely kill many pathogenic bacteria such as Escherichia coli and Salmonella without damaging the flavor and nutritional content of food. Its strong adsorption and penetration ability make it have a strong bactericidal effect, and the disinfection process is not prone to producing carcinogenic substances such as trihalomethanes. It also shows unique advantages in material compatibility and has been widely used in fine processing links such as fruit and vegetable cleaning, meat product preservation, and dairy product production.

By 2025 alone, the domestic demand for food grade chlorine dioxide will increase by 18% year-on-year, which fully demonstrates the strong demand for chlorine dioxide in the food processing industry. Domestic enterprises such as Shandong Huashi Pharmaceutical (whose product name is Xiuba) now have product coverage for global disinfection scenarios in food processing, including raw material cleaning, equipment flushing, environmental spraying, and air purification. It is evident that chlorine dioxide is becoming the new normal for technological applications in global food processing.

2、 Drive the water treatment industry to achieve health popularization

In developed countries in Europe and America, the use of chlorine dioxide for the regulation of chlorite metabolites in their public water supply systems has become so strict that the residual tolerance is only limited to 0.8mg/L. This level of attention comes from the strong adaptability of chlorine dioxide, which not only has the powerful ability to control bacteria, viruses, and biofilms, but also has the characteristics of removing pigments, odors, and iron and manganese ions from water, balancing disinfection and water quality optimization. This precisely reflects the core position of chlorine dioxide in municipal water supply disinfection.

Especially in terms of technical effectiveness, the research report published in "Water Purification Technology" (one of the authoritative technical journals in China) clearly shows that disinfection with only 0.3mg/L chlorine dioxide for 30 minutes can achieve a sterilization rate of up to 99%, and the algae removal rate in the pre oxidation stage can reach over 90%, which is much better than the 97% of sodium hypochlorite under the same conditions. More importantly, chlorine dioxide can maintain a certain effective concentration at the end or dead corners of the pipeline network, and is not easily affected by the acidity or alkalinity of water quality. It can easily adapt to the complex and changing disinfection environment of water quality, which is a significant advantage.

3、 Interpretation of the advantages of chlorine dioxide disinfectant

Compared to traditional chlorine based disinfectants such as sodium hypochlorite, the sterilization mechanism of chlorine dioxide is that it is more soluble in water and less prone to hydrolysis reactions. By oxidizing tyrosine and tryptophan in the cell wall, it breaks down the biofilm barrier and quickly inactivates enzyme proteins, directly blocking microbial metabolism to complete sterilization work. Compared to sodium hypochlorite, this has a more direct hydrolysis property, stronger targeting ability, and faster reaction rate.

In addition, in terms of environmental dependence, chlorine dioxide can maintain its original strong oxidative activity and cell penetration over a wide pH range (pH3-10), which easily defeats sodium hypochlorite that can only emphasize strict limits on the pH range of the solution (pH5.5-7.0), thereby reducing the complexity of process preparation and operating costs.

Not only that, especially in the processing of fresh cut fruits and vegetables, poultry and seafood, chlorine dioxide disinfectant does not produce other chlorine conversion residues on the surface of the food, and has good process adaptability. Moreover, the disinfection effect is long-lasting and beneficial for extending the shelf life. In addition, chlorine dioxide is different from disinfectants such as sodium hypochlorite or peracetic acid. It not only kills quickly, but also does not leave irritating odors. It does not cause strong corrosive secondary damage to metal equipment, and has a relatively high compatibility and environmental friendliness for equipment operation. Therefore, listing it as an A1 level safe disinfectant is an absolute proof of its value advantage.

4、 Policy support, industry bonus, value fission

From a regional perspective, the chlorine dioxide disinfectant industry has been undergoing a value upgrade in recent years. By 2025, the market share of chlorine dioxide in the Asia Pacific region will reach 42.29%, accounting for the dominant global market share. Among them, China has contributed the main increment to the region due to its vast water treatment and industrial production base. Recently, in China, the "Hygienic Standards for Secondary Water Supply Facilities" (GB17051-2025), which will be officially implemented on June 1st, will include chlorite, a byproduct of chlorine dioxide disinfection, as a mandatory test indicator. The number of testing items will increase from 8 to 13. This means that the standardization of hygiene administrative licensing for water related products continues to be strict, which is not only a compliance promotion for chlorine dioxide, but also a differentiation of the advantages of chlorine dioxide while ensuring product quality.

The reason why chlorine dioxide can enter the golden development period is not accidental. Firstly, chlorine dioxide can completely inactivate its difficult to shake Bacillus with only a quarter of the efficacy of sodium hypochlorite; Secondly, chlorine dioxide, which mainly undergoes oxidation reactions, can cut off potential hazards of by-products such as trihalomethanes from the source; Thirdly, it has significant competitiveness in cost control by flexibly adding and reducing other implicit costs. It is not difficult to foresee that chlorine dioxide is proving its market position with its unique advantages.

In Shandong, Huashi Pharmaceutical, a company that has been producing chlorine dioxide disinfectant products for more than 30 years, is also one of the first established enterprises in China to introduce chlorine dioxide. Through decades of technological breakthroughs and continuous scientific research and innovation, it has become one of the top ten authoritative disinfectant brands highly praised in China. Its product line focuses on the development and application of chlorine dioxide disinfectant categories. Each product has a water related approval and disinfection product filing certificate, with an annual output of nearly 10000 tons, widely sold nationwide, and highly trusted in quality. In addition to possessing the A1 level safety product portfolio of the World Health Organization (WHO), it also extensively covers rich disinfection experience in different industries such as food processing, drinking water treatment, and hospital hygiene. Nowadays, the company has accumulated 28 years of service solution capabilities for industry disinfection pain points, providing each partner with systematic services such as customized diagnosis, on-site/remote guidance and installation, follow-up maintenance, technical support, and raw material supply. Xiuba has honed its "true essence" through the use of chlorine dioxide disinfectant, and will continue to deepen its development in the chlorine dioxide market value space, continuously helping cooperative customers achieve worry free production and safe delivery of results.
