Safety Assessment of Products Subject to Microbial Contamination

Some types of cosmetic products may provide an appropriate environment for microbes to grow, such as those containing a higher percentage of water or with other microbial food including proteins, ingredients of natural origin.

Do you know how to assess if your product may provide an appropriate environment for microbes to grow?  What information and documentation do you need for the safety assessment of these products?

To investigate this topic in more detail and explore the requirements for the Cosmetic Product Safety Report (CPSR) in this area, check the CTPA guidance titled ‘Special Considerations for Specific Product Types in the Cosmetic Product Safety Report’, which can be downloaded from the 'safety' tab of the publications page on the CTPA website.  This guidance aims to support cosmetic safety assessors and colleagues in regulatory affairs with additional safety considerations that must be taken into account and must be reported within the CPSR for some specific products, due to their formulation or site of application.

CTPA members can access this guidance for free; it is available to non-members for a payable fee of £90.
