Because of its efficient and safe sterilization, chlorine dioxide has been widely used in the antiseptic preservation of fruits and vegetables, and the sterilization and disinfection of public environments. Chlorine dioxide sustained release agents have become a hot topic of research due to their good stability, controllable release concentration and prolonged release time. The existing chlorine dioxide sustained release agents at home and abroad are divided into solid and liquid states.
Chlorine dioxide has been internationally recognized as a safe, non-toxic, non-"three-factor" effect, no residue after the action of highly active fungicides, deodorants, disinfectants, by the World Health Organization as ai-class disinfectants. Chlorine dioxide can effectively lead to protein denaturation, degradation and loss of enzyme activity, so it can kill general bacteria, viruses, fungi, spores, etc., not only in carrots, melons, tomatoes and other fruits and vegetables to achieve a good application effect, but also to reduce pesticide residues.
Based on the characteristics of chlorine dioxide, a lot of stable chlorine dioxide solution products have been developed at present, but the mode of action is generally soaking and spraying, this way is unstable, the action time is short, the volatilization speed is fast and the concentration is uneven, if the concentration is too high, it is easy to remain on the surface of the product, causing more side effects, and damaging the product; if the concentration is too low, it is difficult to play a role, so that its application is limited.
Therefore, it is key to control the release concentration, prolong the release time, and make chlorine dioxide function more smoothly and continuously. Chlorine dioxide sustained release agents came into being.
Chlorine dioxide sustained release agent is a preparation that uses the interaction between chlorine dioxide and polymer compounds to continuously and smoothly release chlorine dioxide for long-term action within an appropriate period of time.
