Module 1 – Good Manufacturing Practice

Good Manufacturing Practice (GMP) is one of the basic pillars of cosmetic formulating. GMP is universally accepted as a guideline to ensure the safety and consistent quality of skincare products and is mandatory in many parts of the world.

In this module we cover global GMP requirements, ISO 22716:2007 (the international standard for cosmetics GMP), how to create a GMP checklist, getting your lab prepared and understanding the difference between sterilisation, sanisation and disinfection.
