Microbial contamination of cosmetics is in addition to raw materials other than natural ingredients, to affect its safety is another major factor. Generally the cosmetics of pollution in the production process as a pollution; cosmetics in the course called the secondary pollution by pollution.
A pollution: cosmetics raw material itself can be derived from micro-organisms can also be contaminated during production. Therefore, their physical and chemical properties of raw materials, Cosmetics material , moisture content, the production environment and equipment health status, health status of production workers cosmetics etc, the quality of health products.
Cosmetics raw materials used in the production process, the container and the production process can be affected by microbial contamination, especially in the cooling process more vulnerable to pollution filling. Cosmetics raw materials have been a variety of possible microbial contamination, especially in the natural plant and animal ingredients, mineral powders, pigments, such as ion exchange materials susceptible to microbial contamination of water. Some cosmetic formulations rich in water and nutrients, such as mostly cosmetic Cream “nutrition”, which by the addition of various amino acids, protein, or supplements (placenta extract, ginseng, licorice extract, etc.) components and help microbial growth and reproduction. In recent years, biological products of active substances in cosmetics increasingly widespread application, astaxanthin , many functional cosmetics such as high-moisture, anti-aging, whitening, freckle etc by adding biologically active substances or extracts of natural plants and animals to achieve effect. The type of material they are conducive to microbial growth nutrients, therefore controlling microbial contamination of cosmetics, cosmetic issue is to ensure quality and safety of one of the keys.
