Stability Tests

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.:

  • pH
  • Appearance in colour
  • Odour
  • Viscosity
  • Condition of packing
