Environmental protection of preservatives ( 一）
Environmental protection, the requirements of mildew prevention agent itself less toxic (LD50 value is larger), no irritating smell, will not cause corrosion to the skin, in line with the national environmental requirements of Gallei products. It requires broad-spectrum antimicrobial activity, high efficacy, long-term activity, extensive lethal or inhibitory effect on various molds and bacteria, and the use of low concentration, that is, generally referred to as broad spectrum and high efficiency
Preservative, usually referred to in the industry is in the tank, that is, in-can, that is, after the product is produced, not before the use of the state, in the tank requires anti-corrosion effect. Antiseptic is a kind of additive in the wet state in the tank, which is mainly aimed at bacteria, killing and inhibiting bacterial growth
Preservatives: Substances that inhibit the growth and reproduction of microorganisms are called preservatives. Fungicides are substances that destroy and kill microorganisms. Preservatives can kill microbial propagules, but prevent them from developing into propagules and gradually die. Different preservatives have different mechanisms of action. Alcohol, for example, can denature proteins of pathogenic microorganisms; Benzoic acid and paraben can combine with pathogenic microorganism enzyme system, affect and block the metabolic process. Cationic surfactants can reduce the surface tension, increase the permeability of bacterial cell membrane, and make the cell membrane break and dissolve
We can learn about mildew prevention agents from the different roles of mildew prevention agents and preservatives:
Mildew proof agent, usually refers to paint and other products in the dry film state, that is, film, in order to prevent mold growth need mildew proof effect. Anti-mildew agent is in the dry film state, mainly for mold, kill, inhibit mold growth of an additive.
