Each cosmetic product should contain microbiological specifications of the finished product as well as challenge test in the PIF.
Certain cosmetic products may not require those specifications though. Examples of such products are products with a high alcohol content (>20%), products based on organic solvents and products with a high (above 10) or low (below 3) pH. A scientific justification for the lack of microbiological specifications has to be provided, however.
