Certificate in Cosmetic Quality and Stability

Did you know that ANY cosmetic brand, even small cosmetic brands, putting cosmetic products into the marketplace are responsible for the quality and shelf life of that product, even if they have it contract manufactured or formulated? Fulfill this very essential cosmetic quality requirement and protect your cosmetic brand from issues with quality or stability.

Even if your cosmetic formula was prepared by a Cosmetic Chemist, and your product was manufactured by a Cosmetic Contract Manufacturer, the Brand putting the product onto the marketplace is ultimately responsible to have checked that the product meets minimum quality criteria, and holds necessary stability data to support the shelf life of the product. You don’t need to be a licensed lab to run essential quality checks or run your cosmetic shelf life program – but you do need to hold evidence that these steps have been done. Contract these steps out to get the required evidence – OR – learn to do them yourself with our Certificate in Cosmetic Quality and Stability program.

This Certificate program will guide you on basic equipment you will need to run your own tests to check your product quality, especially if you intend to manufacture small batches of cosmetic product for your own cosmetic brand. It also provides you with handy cosmetic quality and stability templates you can use to determine:

  • What sort of tests to conduct on cosmetic products to check for quality
  • What is required, at a minimum, to prove the shelf life of your cosmetic product
  • How to plan your stability testing
  • How to investigate and troubleshoot product quality issues
  • How to predict shelf life and evidence needed to confirm this
  • What results you need before going to market
  • How to get to market fast with minimal risk

Our Certificate in Cosmetic Quality and Stability program also comes with workplace ready templates you can use for your own cosmetic brand:

  • Stability tests for different product types
  • Microbial burden and limits for different countries and product types
  • Stability schedule template
  • Real time and accelerated testing record sheets

If you have started, or want to start your own cosmetic brand, then this is the program to help ensure the quality and shelf life of your products. Our Certificate in Cosmetic Quality and Stability course has been developed to provide the skills, knowledge and templates necessary to comply with Cosmetic Quality checks and shelf life determinations around the world.
