Protective Efficacy Test

The effectiveness of any preservative or cosmetic product is difficult to predict accurately. Therefore, the performance of a formulated end product must be determined by analysis. The aim is to ensure that a product is adequately protected by exposure to relevant microorganisms.

As a result of the Preservative Efficacy Test, it must be proven that adequate protection is provided during the shelf life period. Protective Efficacy Test or Challenge test should be performed at the beginning, during and at the end of the product's shelf life. Organisms are inoculated into product samples as single or mixed inoculums. Samples are taken at appropriate intervals to determine the survivors. Interpretation of the data should be based on pharmacopoeia or other official protocols.

It is carried out to determine the effectiveness of the preservative system in cosmetic products. “Protective Effectiveness Test” is an indicator of the effectiveness of the products against microorganisms to which they will be exposed during use and contact with the environment.
