What is the effect of cosmetic antiseptic?
Bactericidal preservatives are mainly used to kill bacteria or make them lose the ability to grow and reproduce to ensure that the material does not deteriorate during use. Cosmetic preservatives refer to substances added to cosmetics for the purpose of inhibiting the growth and reproduction of microorganisms in cosmetics
It is mainly used in cosmetics to avoid the growth of microbial strains in cosmetics, keep the characteristics of cosmetics stable, so that cosmetics are not easy to change after opening.
In addition, cosmetic preservatives can also help reduce a small amount of bacterial corrosion during the storage, manufacturing and canning of commodity raw materials.
Bactericidal "and" bacteriostatic "difference: the" killing "or" inhibiting "of the microorganism is closely related to its dose or contact time, and may only inhibit the effect at low doses or short exposures, while it may cause killing effects at high doses or long exposures.
Generally, the normal production of cosmetics is mainly bacteriostatic, because cosmetics are produced in a sterile environment during the whole production process, and the packaging materials are also sterile. However, because there are many nutrients in cosmetics, if the secondary pollution in the transportation or use process is easy to lead to product deterioration and stratification, so in addition to the small dose, vacuum packaging and one-time use of cosmetics can not add appropriate amount of preservatives, other cosmetics need to add appropriate amount of preservatives to ensure product quality and extend the service cycle of the product.
