Stability and compatibility test
The primary objective of conducting stability testing is to indicate the relative stability level of a product under the various conditions that it can be subjected to from the moment it is manufactured until the end of its validity.
The purpose of the test is to evaluate whether the product will meet the prescribed physical, chemical and microbiological quality standards, its functionality, safety and aesthetics over a period of time during handling, transport and storage under appropriate conditions.
Based on the stability test results we also assign the shelf life or the period after opening to the product.
The type of packaging also affects the stability of the product as it protects the product from the external environment.
On the other hand, potential leaching of substances of the packaging into the product have to be evaluated. That’s why compatibility between the packaging and its content has to be investigated, in order to ensure that no quality problems are inducted by the type of packaging material used.
