Taking advantage of PVP's good solubility, solubilization, physiological compatibility, bonding ability and complexing ability, etc., in the field of medicine and health, it replaces adhesives, excipients, coating agents, disintegrants, and cosolvents. , Bactericidal and disinfectant, solubilizer, slow-release agent, capsule shell, dispersion stabilizer, film-forming agent, etc. In some cases, such as the United States, Japan, etc., the dosage and effect of PVP in the medical and health field are shown in Table 6.2.
PVP was first used in drug production in my country in the 1980s. In 1985, Zhejiang Research Institute of Chemical Industry and Hangzhou Minsheng Pharmaceutical Co., Ltd. jointly developed a new type of disinfectant PVP-I with PVP as the main ingredient. Later, some manufacturers began to use it.
At the same time, we do the job actively to do research and improvement for 99% USP Bp Polyvinylpyrrolidone Pvp CAS 9003-39-8. Honest to every customers are our requested! We seek progress in a stable manner, implement the new development concept, and strive tirelessly to achieve the strategic goal of building a globally competitive enterprise.
