KNOW ABOUT ANTIMICROBIAL EFFICACY TESTING SERVICES
2
An antimicrobial or preservative is simply known
as a chemical agent which kills or controls the
growth of microorganisms.
3
Antimicrobial Efficacy Testing (AET) is microbial
challenge methodology performed to determine
whether the preservative is fit for a product
formulation.
4
The test also unravels the potential of
preservative system before the expiry date of the
product.
5
There are several procedures of AET carried out
by reputable antimicrobial testing labs such as
6

• Periodic testing

The kill effect by preservative is measured at
regular intervals over a period of 28 days at
certain temperature.
To assess a product's antimicrobial
effectiveness, the product is inoculated with the
individual microorganisms.
7

• AET Growth Promotion
• and Validation

It is recommended to conduct AET validation to
determine the routine testing procedure
capability in the presence of the product.
If the product displays antimicrobial properties,
the capacity of media used in this procedure to
promote microbial growth must be established.
8

• Unmatched Product Categories

The product categories affect the required log
reduction. Products are to be grouped for AET.
9

• Use of experienced lab

The use of an experienced antimicrobial lab
testing can yield the appropriate results to
which one can completely trust.
Before using the lab, make sure the experts
dealing with antimicrobial testing procedures are
highly skilled and have vast experience.
10
Valuable data gathered from the AET studies offer
insight into the product formulation as well as
helping assure the safety and efficacy of the
product.
