Antimicrobial Efficacy Testing (AET)
At Lucideon, we can perform antimicrobial effectiveness testing (AET or PET) to Ph. Eur. and USP on an array of products.
The product is inoculated with a specified number of each challenge organism. Over a period of 28 days the product is examined to determine the number of viable microorganisms which survive at each specified time interval.
Many healthcare products can potentially harbour bacterial growth, including oral products, parenterals, health supplements and cosmetics. Antimicrobial properties can help to reduce bacterial growth on products in case of contamination in the manufacturing process or, more likely, by the end user. Antimicrobials can be toxic so it is important that the minimum amount required is used. We test to USP <51> or Ph. Eur. 5.1.3 for antimicrobial properties, or different types and levels of added antimicrobial agents.
