Stability testing for small cosmetic brands


Starting a cosmetic business is exciting, but did you know:

  • the shelf life of your cosmetic products is YOUR responsibility, even if they have been formulated or manufactured by someone else?
  • not holding stability data could render your cosmetic insurance void if there is a claim?
  • you CAN run your own stability testing, even as an indie cosmetic brand?

Stability testing is essential for:

  • ensuring suitable product quality and safety for consumers over the entire shelf life of a cosmetic product
  • insurance requirements
  • ensuring consumer satisfaction
  • avoiding product recalls
