What is the difference between a cosmetic chemist and a cosmetic formulator?

The terms are often used interchangeably, but 'cosmetic chemist' typically implies a formal science degree and deep understanding of ingredient chemistry, regulatory frameworks, and analytical testing. 'Formulator' can describe anyone who blends cosmetic ingredients — including self-taught indie makers. For regulated markets (EU, Canada, Australia) or complex product types, a degreed cosmetic chemist with ISO 22716 GMP knowledge is generally required by contract manufacturers.
