  Preservation Challenges & Sensitivities Testing

  Posted by ChemistLola on June 11, 2020 at 9:15 pm

  Hi friends :blush:
  Would anyone be able to recommend a few companies for challenge testing of cosmetics? Any guidance would be greatly appreciated! My preference is South Florida, but i’d ship anywhere for challenging.
