The purpose of stability testing is to ensure that cosmetic formulations are stable and can maintain their structure, appearance, pH, viscosity, colour, odour, and microbial quality under a range of conditions to achieve a shelf life.
We offer a 12-week stability test where we will store your cosmetic product in various climate conditions to ensure that your product is stabile through a wide range of conditions. We will then carefully select the appropriate variables to test throughout the 12-week period, e.g.:
- Appearance in colour
- Condition of packing
Testing Sample Requirements
We kindly ask that you submit your samples for testing in their final packaging type and that we have 21 individual samples to run the full 12-week stability test.
