Title Microbiological Safety of Cosmetics and the Role of Product Testing
Introduction MPL Laboratories provides microbial testing of cosmetics to help protect consumers and to help companies comply with existing regulations to avoid costly product recalls.

Sparta, NJ, October 26, 2022 

The U.S. Food & Drug Administration (FDA) reports that cosmetics sold in the United States are required to be safe when consumers use them according to directions in the labeling, or in the customary or expected way. These products must not be adulterated and are also required to not be prepared, packed, or stored in a way in which they may become contaminated or harmful to health. 

Companies that manufacture or distribute cosmetics are legally responsible for the safety of their products, including making sure cosmetics are free of harmful microorganisms. Testing is one of the things manufacturers, importers and distributors can do to help ensure the microbiological safety of a cosmetic product.  

The following is a list of some of the ways cosmetics may become contaminated with bacteria or fungi according to the FDA:

  • Contaminated raw materials, water, or other ingredients
  • Poor manufacturing conditions
  • Ingredients that encourage growth of microorganisms, without an effective preservative system
  • Packaging that doesn’t protect a product adequately
  • Poor shipping or storage conditions
  • Consumer use, such as the need to dip fingers into the product 

MPL Laboratories is dedicated to helping manufacturers, importers, and distributors of cosmetics test for microbial contaminants that could put consumers at risk, jeopardize product shelf life and lead to costly recalls. Their scientists specialize in the microbiological analysis of soaps, shampoos, lotions, topicals, skin care, anti-aging, and beauty products. Testing services take place in MPL’s FDA registered, cGMP and ISO 17025 compliant laboratory to ensure the highest quality results.
