Problems solved by technology

Because of its 100% sterilization rate against bacteria, fungi, viruses, and spores, it has been widely used in medical disinfection abroad, especially in the field of oral cavity for disinfection of medical materials and instruments, anti-mold, mouthwash disinfection, deodorization and environmental disinfection , but it has not been widely used in my country
Chlorine dioxide is a yellow-green gas at room temperature. It has good water solubility, but it is unstable and easy to volatilize. It can only be stored for 8 hours at room temperature, and it is difficult to store for a long time.
"It can be seen that the disinfection wipes currently on the market are all low-level disinfection methods, which cannot meet the hygienic requirements and market demand for controlling the spread of viruses at all.

Abstract

The invention discloses a composition capable of slowly-releasing chlorine dioxide, which contains parent substances of chlorine dioxide, organic acid and conjugate base thereof, or organic acid and pH buffering agent to form a stable buffer system for keeping pH of the composition being 5-8. Meanwhile, the invention discloses disinfection wet wipes prepared from the composition. The invention is characterized in that the concentration of apparent chlorine dioxide of the composition is stably maintained in a low range by adjusting the mixture ratio of parent substances of chlorine dioxide and organic acid in different pH buffer systems according to a chemical reaction equilibrium principle, thereby realizing the same disinfection effect and avoiding using complex slowly-releasing systems for chlorine dioxide.

Description

technical field [0001] The invention relates to a composition, in particular to a composition capable of slow release of chlorine dioxide and its application in sterilization and disinfection products. Background technique [0002] Chlorine dioxide is currently recognized as a highly efficient, low-toxic, rapid, and broad-spectrum fourth-generation new type of bactericidal disinfectant. It has been recognized by the World Health Organization (WHO) for its strong bactericidal power, non-carcinogenic, and non-secondary pollution characteristics. Listed as A1 grade disinfectant. As the most ideal chemical disinfectant at present, chlorine dioxide has replaced aldehydes, phenols, and quaternary ammonium salts, and has been widely used internationally. Approved by the US Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA), it is used in food preservation, processing, disinfection of drinking water, sterilization, deodorization, industry, agriculture ...
