The microbiological quality of raw materials has an important impact on the microbiological quality and safety of cosmetic products. The raw materials producer has to guarantee a consistent quality and to ensure adequate hygiene and preservation measures during manufacture, storage and transport of the materials. For each raw material microbial limit values have to be defined. The cosmetics producer has to avoid additional microbial contamination of the raw materials as well as microbial growth in the production site and in the finished product. This needs hygiene measures, a suitable processing of raw materials and an adequate preservation of the product. Microbiological controls have to be established to safeguard the entire raw material process. Valid microbial examinations, risk-assessment and expert-decisions need adequate personal qualification. To fulfil all the microbiological tasks a quality management-system (MQM) should be employed.
