About the use and influencing factors of antiseptic & antifungal agents
Other applications of Kathon preservatives
Kathon preservatives is also widely used in photographic chemical sensitizers, indoor air fresheners, audio tape materials and plant growth regulators.
It has high-efficiency, broad-spectrum bactericidal performance, good compatibility, can maintain activity in a large pH range, small addition amount, fast onset, strong bactericidal power, convenient use and low price. More importantly, Kathon class of fungicides are environmentally friendly “green products”, so they have been widely used in developed countries. Kathon preservative has strong biological activity, which can inhibit bacteria and sterilize. It can solve the problems of fermentation, mold, deterioration and bacteria exceeding the standard caused by fungal infections. It can be applied not only to cosmetics and detergents. It can also be used in many industries and industries such as industrial sterilization water, machine tool coolant, paint, paper, daily chemical, paint, cosmetics, petroleum and other industries, as well as oilfield water injection and sewage treatment. Internationally, it is mainly applied to the sterilization and anti-mildew of cosmetics, which is more common in facial cleanser, hair-fixing conditioner, washing shampoo, etc.
1. Inorganic stabilizer
The substances which can be used as inorganic stabilizers for the carson preservative are mainly metal nitrites or nitrates and metal salt complexes. There are many reports on metal nitrite or nitrate stabilizers. The metal salt complex can increase the thermal stability of the carson solution while maintaining its biological activity. When sodium copper citrate is used as a stabilizer, the sodium copper citrate itself has a killing effect.
2. Organic stabilizer
Organic stabilizers are further divided into carbonyl compounds, halogen-containing organic compounds and other organic stabilizers.
The bactericidal properties of the kathon preservative have a broad spectrum, can kill algae, fungi, bacteria, and at the same time have a penetrating effect on mucus, so that the carcass-treated microorganisms cannot synthesize enzymes and secrete adhesion before cell death. Sexual and biofilm-forming substances, sterilization is more thorough; Carson is also effective at low concentrations, generally effective concentration of 0.5mg / L, can control the growth of bacteria, which is unmatched by other agents; Good miscibility.
Kathon preservatives are physically compatible with chlorine, corrosion inhibitors, scale inhibitors and most anionic, cationic and nonionic surfactants at normal concentrations, such as the interaction between Broll and Cason In combination, the ratio of the two is 1~16:1, and the product has synergistic effect and spectrum sterilization effect;
The Kathon preservative can effectively form the formation of slime, which can easily pass through the surface of the slime, effectively killing microorganisms in the slime, and effectively preventing the slime layer when the medicament is put into a cleaning system. Growth; harmless to the environment, the agent degrades rapidly in aqueous solution, can be naturally degraded to non-toxic substances when diluted to the use concentration, does not cause environmental pollution; has a wide range of pH values, even in Alkaline system can still maintain high stability, generally pH value can be applied in the range of 5.5-9.5; low toxicity, long interval of administration, and because it has no surface activity, the agent does not produce foam during use.
