    Hello,

    Does anyone know of a good preservative for hemp oil? The shelf life is extremely short and I would like to be able to keep it around as a skin moisturizer.
    Thank you,
    Dave

    Dave, you do not need a preservative for hemp oil … what you need is an antioxidant … as Belassi said, you can add Vitamin E (tocopherol) or a CO2 Extract of Rosemary.  Either will help in your hemp oil becoming rancid.

    Belassi and MarkBroussard, Thank you very much for the advice. I will try both vitamin E and/or the extract of rosemary and play around with the ratios. I hope to find a way to be able to keep it out of the refrigerator and keep it in the bathroom for convenience. Thanks again!

    @David:

    Yes, 0.1% to 0.5% of either works well.  Yes, they work with most oils.  They are not mutually-exclusive, you can add a bit of each or use them individually.
