Cosmetics Microbiology Testing

From glittery eye shadow, to SPF anti-aging skincare face creams, to water-proof eyelash mascara and glossy long-lasting lipsticks, cosmetics microbiology testing is important. Cosmetics come into contact with the human body and need to be safe from microorganisms which might have an adverse effect and cause harm to humans.  The daily use of cosmetics after contact with the skin, eyes and hair might transfer bacteria and other microorganisms back to the cosmetics where the darkness and ingredients in the cosmetics may offer a perfect breeding ground for microbial growth.

Cosmetics Microbiology Testing is important to ensure the product safety and compliance of cosmetics. Manufacturers are responsible for ensuring the safety of cosmetics for consumer use such as the absence of harmful microorganisms which can be harmful bacteria or other disease causing organisms.  Cosmetics do not have to be sterile, but they must have a preservative system strong enough to take care of harmful microbial contamination. Cosmetic microbiology testing, preservative efficacy testing, shelf life testing and general microbial identification must be performed for a cosmetic to enter the market.

Manufacturers must conduct microbiology testing to ensure they’re safe to use when stored according to directions on product labeling. The presence of microorganisms can cause spoilage or even chemical changes that can be potentially harmful.

Some ways that cosmetics products maybe contaminated include:

  • being made using contaminated ingredients
  • made under poor manufacturing conditions
  • using ingredients that encourage the growth of microorganisms
  • incorrect packaging
  • poor shipping and/or storage conditions

Some microorganisms which can cause problems include: pseudomonas aeruginosa bacteria in eye products such as cream, shadow, and liner.
