  • How to calculate melting point of final product?

    Posted by briley57 on April 27, 2022 at 1:13 pm


    Im wanting to figure out at what temperature could I expect my lip balm to melt. I want to be able to give my customers a number in Fahrenheit so they know what temps to avoid so that their lip balms don’t melt. 
    Would I have to figure out the melting point of each ingredient and then take averages? I’ve been out of gen chem for 9 years, so I’m a little rusty 😅

    thank you!

    for reference, here are the ingredients used from highest amount to lowest:

    Avocado Oil
    Stearic Acid
    High Melt Point Shea Butter
    Candelilla Wax
    Jojoba Oil
    Vitamin E Oil
    Essential/Flavor Oil

    The easiest way is to heat up a sample and observe it until it melts.

    Trying to calculate a melting point is probably too complicated as it’s difficult to know how each ingredient impacts the crystalline structure of the balm.
