Glutaraldehyde is a high-level disinfectant and sterilant that is effective against bacterial vegetative cells, bacterial spores, fungi, and viruses. It is commonly used for the disinfection and sterilization of clinical endoscopes. During the disinfection of hospital endoscopes with glutaraldehyde, the effective concentration gradually decreases due to dilution and consumption. Accurately determining the glutaraldehyde content in […]
I. Introduction As the problem of bacterial resistance becomes increasingly severe, the development of antimicrobial drugs with novel structures and new mechanisms of action has become a key focus in drug research. Due to issues such as single targets and the rapid development of resistance, the clinical efficacy of traditional antibiotics has been significantly challenged […]
In daily life, it’s common to see households using humidifiers to add moisture to the air. But why is humidifying the air necessary? How should humidifiers be used correctly? What is the proper way to use a humidifier? The Importance of Air Humidity According to national indoor air quality standards, good indoor air quality requires […]
Throughout the entire production, storage and usage process in the cosmetics industry, preservatives serve as core ingredients that ensure product quality, usage safety and shelf stability. They effectively inhibit microbial growth, preventing product deterioration and failure. As one of the industry’s commonly used preservatives, Bronopol (chemical name: 2-Bromo-2-Nitropropane-1,3-Diol) is widely adopted for its outstanding preservative […]
Industrial microbial contamination is the primary cause of system corrosion, efficiency decline, product spoilage, and shutdowns for cleaning. Traditional oxidative biocides suffer from significant pH sensitivity, prone to byproduct formation, equipment corrosion, and poor compatibility issues; while conventional non-oxidative biocides exhibit drawbacks such as slow onset, high residues, and poor biofilm penetration. DBNPA-based biocides have […]
Glutaraldehyde is an indispensable key chemical in the fields of medical disinfection, dental therapy, vaccine manufacturing, and biological research. As a typical saturated dialdehyde compound, it exhibits unique chemical reactivity and biocompatibility, making it a core raw material and auxiliary reagent in modern biomedicine, pharmaceutical industry, and industrial production. This guide systematically elaborates on the […]

Introduction to Peat and its Significance Peat, often considered a humble natural material, has recently taken center stage in environmental remediation efforts. Researchers at Xihua Normal University, led by the innovative Professor Li Wenbin, have unveiled peat’s untapped potential in combating agricultural pollution—a revelation that could reshape our approach to environmental management. Why Peat? An […]
As an engineer in a chemical plant’s water treatment workshop, I know drinking water safety is central to public health. Bactericides are key fine chemicals that ensure drinking water is biologically safe. In real-world operations, drinking water treatment must address natural bacteria in water sources, pipeline biofilms, and secondary contamination. The selection, dosage control, and […]
