Abstract
Cosmetics bring us cleanliness and beauty. Therefore, consumers have good image to these products and can not imagine microbial contamination. However, microbial control of cosmetics is rather difficult than that of medical supplies and foods because of its special properties. There are three requisites for prevention of microbial contamination in manufacturing products, such as prescription of preservatives, facilities of production and control during manufacture. In this paper, we want to introduce important points in the aspects of production (facilities of production, environment of production, control of raw materials, washing and sterilization of facilities, microbial inspection of products and so on).
