Toothpaste is an oral hygiene product, and its most basic function is to clean and maintain oral hygiene. Chlorine dioxide perfectly meets this requirement and is suitable for toothpaste products.
In the toothpaste industry, researchers have been exploring whitening toothpaste formulations. Whitening toothpaste typically has a pH between 9 and 10, and peroxides are often chosen for their whitening effect, but these are difficult to meet in terms of both processing and efficacy. Hydrogen peroxide decomposes rapidly in the presence of trace amounts of iron and copper ions, and releases oxygen upon heating—an irreversible process that renders the toothpaste ineffective. Because hydrogen peroxide is unsuitable, urea peroxide, known for its stability, is chosen . However, urea peroxide requires a high concentration and a long treatment time to achieve its whitening effect. Dental clinics typically prepare whitening pastes containing urea peroxide , requiring several hours of application with braces to achieve the desired whitening effect. Toothpaste requires large amounts of urea peroxide to achieve this , and the effect is not significant. Bleaching powder works by forming hypochlorous acid under acidic conditions. Hypochlorous acid decomposes, releasing reactive oxygen species that have bleaching properties. Since toothpaste typically has a pH between 9 and 10, it does not release oxygen and is therefore ineffective.
Zhang Zhifeng conducted an exploratory study on the use of chlorine dioxide in toothpaste. The toothpaste production materials used in the experiment were those commonly used in toothpaste production, and the formula was based on a standard, mature formula with varying amounts of chlorine dioxide added. The concentrations of chlorine dioxide added to the base formula were: 1× 10⁻⁶ %, 2×10⁻⁶ % , 5× 10⁻⁶ %, 10× 10⁻⁶ %, 15× 10⁻⁶ % , 20×10⁻⁶%, 25× 10⁻⁶ % , and 30×10⁻⁶ % . The experiment showed that consumers could accept chlorine dioxide concentrations below 20×10⁻⁶ % , but higher concentrations caused oral discomfort. Brushing teeth with toothpaste containing 1× 10⁻⁶ % chlorine dioxide on individuals with oral inflammation showed significant symptom relief on the first day, near-complete recovery on the second day, and complete recovery after three days. Furthermore, prolonged use resulted in no discomfort. Based on these experimental results, it was found that using 10×10⁻⁶ % chlorine dioxide as a toothpaste additive maintains essentially unchanged physicochemical properties, is heat- and cold-resistant, and provides no discomfort after prolonged use. Oral symptoms disappeared, and teeth became whiter than before. Simultaneously, soaking extracted teeth in 10×10⁻⁶ % chlorine dioxide toothpaste resulted in a whitening effect after 2 hours. While some progress has been made, significant work remains to be done to integrate chlorine dioxide into toothpaste production.
Chlorine dioxide, as a toothpaste additive, can both whiten teeth and kill oral bacteria. Furthermore, toothpaste can be made without additional preservatives, as chlorine dioxide is a highly effective, fast-acting, and safe preservative. In addition, adding chlorine dioxide to toothpaste requires no special processing conditions and is easy to implement. Therefore, chlorine dioxide has enormous potential for development and practical application in toothpaste.
Traditional whitening toothpastes often suffer from poor stability and limited effectiveness due to their commonly used ingredients. Research shows that adding 10×10⁻⁶% chlorine dioxide to toothpaste provides whitening, anti-inflammatory, and antiseptic effects. It is stable, easy to process, and safe to use, making it a promising candidate for application in the toothpaste industry.

Chlorine dioxide is safe, highly effective, and leaves no residues, making it ideally suited for four core application scenarios: healthcare, drinking water, food processing, and public environments. With over 40 years of deep industry expertise and comprehensive certifications, Huashi Pharmaceutical provides scientific and reliable disinfection solutions.
Chlorine dioxide is not a chlorine-based agent; rather, it is a safe, highly effective, and potent oxidant. It achieves sterilization solely through oxidation—without generating carcinogenic byproducts—and is officially classified as a distinct category of disinfectant, widely utilized in applications such as drinking water treatment and food processing.
## Abstract Driven by stricter environmental regulations, public health demands, and the upgrading of China’s water treatment industry, the chlorine dioxide generator market continues to expand in 2026. Intelligent, energy-saving, and customized equipment has become the mainstream development trend, while market competition is increasingly shaped by technological innovation, compliance qualifications, and integrated service capabilities. This paper analyzes the current market status, competitive risks, and future demand trends of China’s chlorine dioxide generator industry, and examines how companies such as Shandong Huashi Pharmaceutical strengthen competitiveness through intelligent technologies, scenario-based solutions, and integrated “equipment + chemicals + services” models.
An in-depth analysis of China’s chlorine dioxide disinfectant market in 2026, covering market share distribution, regional demand trends, industry competition structure, and future growth opportunities. The article explores how environmental policies, public health standards, and technological innovation are driving the rapid development of chlorine dioxide disinfectants across water treatment, food processing, healthcare, and environmental sanitation sectors. It also highlights the competitive advantages of leading manufacturers, the rise of intelligent disinfection solutions, and the industry’s shift toward high-purity, eco-friendly, and scenario-based products.
Chlorine dioxide is widely used in the medical field due to its high efficiency, low toxicity, and broad-spectrum bactericidal properties. It can be used for skin care, gynecological irrigation, ophthalmic treatment and contact lens disinfection, and surgical wound irrigation. At the same time, in dentistry, it can effectively control biofilm pollution in dental water supply systems, reduce the risk of cross-infection, and has no secondary pollution and minimal irritation to the human body.
Chlorine dioxide is highly effective against a variety of bacteria and viruses. Solid slow-release products allow for precise control of release characteristics, ensuring safety and environmental friendliness. It has wide applications in the daily chemical industry, enabling the development of various products for air purification, medical disinfection, mold prevention and deodorization, food preservation, and personal care. Combining bactericidal, disinfectant, deodorizing, and mold-preventing functions, it is low-cost, highly adaptable, and represents an important development direction for next-generation green disinfectants.
Chlorine dioxide is a high-efficiency bleaching agent with selective oxidation that does not damage fibers and is environmentally friendly with no toxic chlorinated compounds. It can be used to produce high-grade pulp. Developed countries have long used it. Research and application in my country started later. The equipment was first introduced in the mid-1990s. After the 21st century, it was widely used in newly built large pulp lines. Some companies use a process that combines chlorine dioxide and chlorine. Small generators are also being promoted. Its application will continue to expand in the future.
Stable chlorine dioxide, as a highly efficient and safe new generation of disinfectant, is widely used in breweries. It can be used to disinfect raw water to produce sterile water, inhibit mold, reduce malt color, and improve malt quality during malting. It can also replace traditional high-temperature processes to efficiently disinfect process pipelines and equipment. Furthermore, it can be used to disinfect the fermentation and bottling workshop environment through spraying or fumigation. It is safe and non-irritating, and comprehensively improves the level of microbial control and product quality in beer production.
