Home Cosmetic Science Talk Formulating General Base product

    A lot of companies sell base products that can be customized with the purchasing companies’ individual fragrances. How does that work with testing? I was under the impression that PET testing would not be required because the product being sold should have already met those requirements. But what about stability testing? I would think with the variety of fragrances that the base product could have added to it that stability testing would be necessary, but I’m not sure and would love any input from those with more experience. Thank you!

    Ultimately you are responsible for proving your products are safe. The base sellers don’t have to prove anything if you customize it in some way.

    Technically once you add any additives and change the Formula from the base, the testing on the altered base is invalid. PET/Stability is Formula dependent.
