Chemicals you don't know in life preservative

Preservatives are a foreign word. They were first mentioned by European scholars in ancient Egypt to prevent the decay of corpses. With the deepening of research, it has been found that organisms are mainly caused by microbial growth, reproduction or oxidation. Therefore, preservatives are substances that are naturally or chemically synthesized and used in foods, cosmetics, wood, paints, etc. to inhibit the growth, reproduction, or prevention of chemical changes. A bacteriostatic agent is a substance that is naturally or chemically synthesized and used in products such as foods, cosmetics, wood, paints, etc., which can inhibit the growth and reproduction of microorganisms and prolong the shelf life of the products. Bactericides, also known as biocides, can quickly kill a class of compounds in the system.

Generalized preservatives include bacteriostatic agents, bactericides, antioxidants, and salt and spices;

There are no obvious boundaries between bacteriostats and fungicides. Some high-concentration bacteriostats also have bactericidal effects, such as formaldehyde; however, there are different focuses and detection methods. The bacteriostatic agent focuses on the long-term inhibition of microorganisms. The general detection method is the minimum inhibitory concentration and the challenging experiment; the bactericide focuses on the immediate killing of microorganisms, and the detection method is the minimum killing concentration and killing rate experiment.

       The preservatives referred to in the cosmetics industry are strictly bacteriostatic agents. In 2007, INCI specified 56 kinds of antiseptic ingredients; in recent years, with the deepening of application and research, some substances that have antibacterial ability but are not classified as preservatives have also been discovered and used in the cosmetics industry. This book is collectively referred to as a bacteriostatic agent.
