(in Polish) Basics of cosmetics microbiology 2600-OG-EN-BCM

Cosmetic product in accordance with art. 3 of Regulation of the European Parliament and of the Council (EC) No. 1223/2009 of 30 November 2009 on cosmetic products should be safe for the health of the consumer under normal or foreseeable conditions of use, within the shelf life assumed by the responsible person. Standardized and reproducible test methods should be used to assess the microbiological purity of a cosmetic product. For this purpose, we will use the protocols contained in ISO standards. We would like to determine the number of yeasts and molds, count and detect aerobic mesophilic bacteria, as well as detect specific and non-specific microorganisms in cosmetics. We also would like to familiarize participants with carrying out product preservation tests, but due to the 28-day incubation time, we will not conduct the full protocol, only a shortened version, but consistent with the procedure after 28 days.
