Myth
#12:
REAL essential oils without additives DO NOT Freeze because there is
no water in them. If there is no water left and nothing is added to
an essential oil like peppermint, it shouldn’t freeze.
The truth is EVERY essential oil will freeze (just as every other
liquid on earth will) if you get the temperature low enough and water
has nothing to do with it. There are several oils that will freeze in
a household freezer and some in the refrigerator and still others
that are solid at room temperature. Every oil has a different
freezing point and many times we see crystallization of a single
component that is a solid at room temperature in pure form. So when
the temperature is reduced it's not uncommon to see such solid
components start to fall out of solution if their concentrations are
past the saturation limit of any given temperature. In the ridiculous
example of peppermint being published on the internet by the gullible
robots who know nothing about chemistry, we see they are claiming
that if a peppermint oil solidifies in a household freezer then by
all means it must be bad. Apparently the misinformed don't understand
that that the main component of peppermint oil is menthol. Menthol in
pure form is a glass-like needle crystal (see picture) that can
easily crystalize in a freezer from various mint oils if the level of
menthol is past the saturation point at any given temperature. High
menthol is typically a desirable attribute of a good peppermint and
the higher menthol mints will have a sweeter, cleaner aroma and, as a
result of this higher menthol, are more susceptible to
crystallization at lower temperatures. An inferior low-menthol mint
oil will not show crystallization in a freezer because the menthol is
not past the saturation point in that temperature range. The menthol
in peppermint can range from 30-50%. Mint oil that has menthol
content in the upper 40s (getting close to 50%) can crystalize in a
household freezer, while cheap 33% menthol Indian peppermint, like
the one that the MLM reps are saying is the good peppermint, can't
crystalize because its so inferior in its menthol content that it
would take a much lower temperature to solidify (and I know for sure
that its low grade Indian oil because I have actually analyzed it).
Of course this company portrays an image of having US grown
peppermint, but at least a few lots have been nothing put pure Indian
material that is less than half the cost of US peppermint.
Some other common examples of natural oil components crystalizing
in at freezer temperatures are things like cedrol in Texas cedar wood
oil, menthol in corn mint oil, methyl thujate in giant arborvitae
wood oil, nepetalactone in catnip oil and thymol in thyme oil just to
name a few. There are some oils that will crystalize merely in the
refrigerator, for example rose oil from Bulgaria has waxy hydrocarbon
components that will solidify giving the oil a solid gelatinous
appearance. And then there are even some steam distilled oils, for
instance Zadravets oil from Bulgaria (Geranium macrorrhizum) and
Orris root (Iris pallida), that are completely solid at room
temperature.
These are just a few examples of oils that solidify at sort of the
normal ranges of everyday accessible temperatures, but make no
mistake, EVERY essential oil will solidify at some point, even the
low quality peppermint oil that didn't freeze in the misinformed
examples would solidify, its just that the freezer used in the
"experiment" did not go down to low enough temperature and
probably needed another 10 to 20 degree drop before solidification
would occur.
Dr. Robert Pappas is a chemist with
more than two decades of experience in the essential oil industry. He
has worked extensively with professionals from around the world, and
focuses primarily on essential oil analysis and education, performing
quality and purity testing for clients large and small. His opinions
are widely respected in the essential oil industry. For a time, Dr.
Pappas' relationships with growers prompted him to begin sales of
essential oils to better serve the needs of his customers as they
sought the best options for essential oil purchases. It was during
this period of time that Welcome to Life! began. Although Dr. Pappas
later sold the burgeoning business to his brother, we continue to
provide our oils exclusively from from this source. We feel confident
that the oils remain as pure and amazing as they were under Dr.
Pappas, and are pleased to offer them to our clients.
Dr. Pappas continues to study, analyze,
and educate about essential oils. With his permission, we reprint his
