Many ingredients in cosmetics are nutrients for the growth and reproduction of microorganisms, and during the production and use of cosmetics, they can easily be contaminated by microorganisms. Therefore, it is necessary to add an appropriate amount of preservatives.

Many ingredients in cosmetics are nutrients for the growth and reproduction of microorganisms, and cosmetics are easily contaminated by microorganisms during production and use. Therefore, it is necessary to add an appropriate amount of preservatives, and we should view the preservatives present in cosmetics rationally and scientifically. In our country, all cosmetics must undergo toxicological testing or risk assessment before being marketed. Generally speaking, cosmetics that use preservatives strictly according to the requirements of the "Cosmetic Safety Technical Specifications" are safe.

Why are preservatives added to cosmetics?
The environment we live in is a world full of microorganisms. Once the seal of purchased cosmetics is opened, they can easily be contaminated. If they do not contain antibacterial substances, they can quickly deteriorate even if stored in the refrigerator.

Many ingredients in cosmetics are nutrients for the growth and reproduction of microorganisms. Under suitable temperature and humidity conditions, microorganisms can grow and reproduce rapidly. During the production of cosmetics, if the cleanliness and disinfection of equipment and the environment are not thorough, it is easy to become infected with microorganisms. In addition, when our hands come into contact with cosmetics, we may also introduce microorganisms into them. Preservatives are substances used to inhibit or prevent the growth and reproduction of microorganisms, thereby preventing product spoilage. To ensure that cosmetics are safe and effective during production, use, and storage, it is necessary to add one or more preservatives to inhibit microbial proliferation and ensure that the product does not deteriorate due to contamination within its shelf life.

There are many types of preservatives, and there are more than a hundred chemical preservatives that can be used in cosmetics. For safety reasons, many countries around the world have regulations regarding preservatives used in cosmetics. In our country, the "Cosmetic Safety Technical Specifications" stipulates that there are 51 types of preservatives that can be used in cosmetics, and it specifies the varieties, usage scope, and restrictions of permissible preservatives. Antibacterial components not listed in the permissible preservatives list cannot be used in cosmetics at will.
