Inorganic and organic antiseptic
Bactericidal preservatives are mainly used to ensure that materials do not deteriorate during use by killing bacteria or making them lose their ability to grow and reproduce. Bactericidal preservatives can denature proteins in microorganisms, reduce the activity of cells, promote the death of bacteria, and can also mutate the cellular genetic genes of microorganisms or interfere with the activity of enzymes inside cells to make it difficult to reproduce.
What is an inorganic antiseptic:
According to different principles, it can be divided into two types: reduction and oxidation. Oxidizing antiseptic is the use of oxidation capacity, so as to play a bactericidal effect, this bactericidal effect is strong, but the chemical property is unstable, easy to decompose, the effect is not lasting, so it is used for equipment, containers, semi-finished products and water disinfection and sterilization; Reductive antiseptic is due to its reducing ability to have bactericidal effect and bleaching effect, such preservatives are mainly used in bleach.
What is an organic antiseptic:
Organic bactericidal preservatives have the characteristics of high efficiency, low toxicity and good biodegradability. At present, the main organic fungicides are organic sulfur, organic bromine and heterocyclic compounds containing nitrogen and sulfur, etc.
In recent years, the most widely used bactericidal preservatives are casone, whose main components are 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl4-isothiazolin-3-one (MI), which have a broad spectrum and long-term effect on killing a variety of bacteria, fungi and yeast with low dosage. Applicable pH range is wide, 2.0-9.0 can be used; Miscible with water, can be added in any process of antiseptic. Can be widely used in coatings, adhesives, printing glue and other waterborne products antiseptic sterilization, among which KG-35 can be dedicated to water treatment, paper industry efficient sterilization, etc., its active ingredient is 2 kinds of isothiazolinone derivatives, has been widely used in the world.
