Simplify Preservative Efficacy Testing

Even though your products are free of harmful microorganisms when they leave your door, the multiple-use nature of cosmetics and personal care products means they are constantly exposed to contaminants by their users. 

Preservatives are used to ensure products remain free of harmful levels of microorganisms throughout their shelf lives. Determining the appropriate mix and concentration of preservatives with the Preservative Efficacy Test (PET) or Challenge Test can be challenging. bioMérieux offers solutions to reduce the challenge of the Challenge Test.
