  • Rose Bulgarian…scent morphing over just a few months….

    Posted by graillotion on December 26, 2021 at 3:59 am

    I have been using a 3% Rose Bulgarian (the balance is Jojoba)…to scent a face cream.  Within a few months, it no longer smells the same….and not for the better.

    Is this morphing normal…or likely a reaction with another ingredient?

    When I use a FO…or some citrus EO’s…I do not seem to have this issue.  Is rose prone to this?

    Aloha, and Merry Christmas.

    The problem might be rose oxide, the main flavour component in essential rose oil. It has a very low scent threshold (one can already smell a ppb) coupled with it’s low concentration = it may for example evaporate to a degree even if the bottle seems hermetically sealed.
    Store expensive EOs in the freezer.

    Sorry…I should have been more clear.  
    The scent only morphs…when included in a finished cream.
