To guarantee the quality of a cosmetic product and the safety for the consumer, it is necessary to carry out regular routine microbiological controls from every batch of the finished product before market approval. Generally, these controls comprise the determination of the bacterial count of the product and testing for sufficient levels of preservation (microbiological challenge test). Only if there is a justified case for an exception, such as the product having a high alcohol content, is it possible to forego this testing.
In the EU, the SCCS “Notes of Guidance for the Testing of Cosmetic Substances and their Safety Evaluation” regulates the necessary testing and safety controls. In the evaluation of the quality and safety of cosmetic products and ingredients, Switzerland also supports the SCCS guidelines.
As a GMP-accredited and FDA-registered contract laboratory in Switzerland, we can offer you holistic consultation in the areas of microbiology and hygiene monitoring.
If you would like to know what tests need to be carried out on your cosmetic products, and how the results should be interpreted, we can provide support.
