While stability and challenge testing are performed during development, microbiological batch release testing is an ongoing obligation. Every batch of cosmetic product must be verified free from harmful pathogens before it reaches the consumer.
What is Microbiological Sampling?
Microbiological sampling involves taking representative samples from a production batch to test for microbial contamination. This ensures that the manufacturing process was hygienic and that no contamination occurred during filling.
Key Parameters Tested
- Total Viable Count (TVC): The overall number of bacteria, yeast, and mold present in the product.
- Pathogen Detection: Specific tests for harmful bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans.
Why is it Critical?
Contaminated cosmetics can cause serious eye and skin infections. For products used around the eyes or on mucous membranes, the limits are even stricter (Category 1 products). Regular testing protects your brand reputation and, most importantly, your customers' health.
