Application of disinfection and sterilization surfactant
The application of disinfectants in various industries has become more and more extensive, and their performance requirements have become higher and higher. The use of traditional disinfectants such as phenol, formaldehyde and chlorine preparations has fallen sharply. Improved, the traditionally more harmful germicidal disinfectants have largely withdrawn from the market in the civilian field, such as organotin, dithiocyanomethane, and acrolein. In comparison, disinfectants composed of surfactants have low toxicity and performance. Gentle, complete sterilization and good environmental compatibility. Surfactants with emulsifying and solubilizing properties generally have strong antibacterial properties. The strength of antibacterial is usually expressed by the minimum inhibitory concentration (MIC). The smaller the value, the stronger the antibacterial. It is not possible to distinguish bacteriostatic and bactericidal effects with MIC. However, surfactants generally show antibacterial activity at low concentrations and bactericidal effects at high concentrations. In fact, on many occasions, these two effects are simultaneously played, so they cannot be separated from each other, so they are collectively called antibacterial disinfection, commonly known as disinfection. The antibacterial and disinfection surfactants currently on the market are mainly cationic and zwitterionic surfactants. There are more than 60 commonly used varieties, and their antibacterial and disinfection characteristics are different. Because of the currently developed surfactant disinfectants for water-soluble viruses and green Pseudomonas, mold, and anti-mutagenic bacteria generally have insufficient efficacy and poor comprehensive performance. Therefore, people urgently hope to develop surfactants that meet the following conditions: effective at low concentrations, the time to produce effects is fast; antibacterial spectrum range It is a substance that is effective against viruses and mildews; even if there are changes in protein, dirt, soap, calcium ions, and pH, the effect will not be significantly reduced; it is selective for antibacterial effects; non-irritating to human skin; use After the waste, no pollution to the environment; does not corrode containers, utensils, etc. In the past 20 years of research, some domestic companies have been very mature in the research of disinfectants.
