- Microorganisms can survive and spread in cosmetic, pharmaceutical and food products without preservatives. Preservatives are regularly added to all industrial preparations intended to be stored or preserved to prevent microbial growth over time.
- Microbial contamination during the manufacture of an industrial product is common, even when the starting ingredients put into said product are "clean", ie without the presence of contaminating microorganisms.
- Water for example, which is ubiquitous in most cosmetic, pharmaceutical or food products, must be free from contaminating microorganisms. All other ingredients should also be screened for the presence of contaminating microorganisms.
