    Hi,

    Wonder if a company will perform a test for making sure that the content remains as how it is intended to be (or doesnt react with the packaging). What is the test (if there is)?
    Thank you in adv. for your sharing and inputs.
    Cheers,
    Young Lia

    I am aware of stability test, but how far will it cover leaching of plastic/container to the content?

    You would have to contract with a testing lab seperately to analyze the chemical leaching into your product. It’s not cheap to do this - if this is a large concern, most folks would simply use glass packaging so that they didn’t have to worry about it.

    We just had a quote done on this because we were looking at running a stability at a different temperature along with our own stability. The quote was $30,000 for 6 months of testing to give you an idea.

    Wow…

    So what is the norm out there then (for cosmetics such as lotion/ointment)? Just grab a ‘standard’ plastic packaging like LDPE/HDPE and run PET only?
    My question was originated from my observation::: when I stored the petrolatum based product in a zip lock bag, it made the bag creased. Assuming there is some kind of reaction ….

    You could probably find a packaging engineer to consult with for substantially less.
