  • What do you use for stability tests?

    Water bath? Oven? Incubator?

    I came across a dry block heater and it seems like it would be the perfect thing for stability testing. The only downside is that it cannot accommodate the actual product packaging, so that would require a separate test. But I’m thinking of picking one up to be able to stability test a wide range of formulations all at once. Does anyone else do this?

    Agree with @MakingSkincare

    Ideally, you would be able to test your product at elevated temperatures in the final packaging.
