STORING ESSENTIAL OILS
Because essential oils are affected by sunlight they should be sold and stored
in dark glass bottles, with stoppered caps. Make sure that the cap is on
securely and the bottle stored up-right in a cool dark place. The oils should be
stored out of sight and the touch of children. Remember that children,
especially small ones, are very inquisitive. Never store essential oils in
plastic bottles. Good Essential oils should keep for several years if properly
stored, though the oils of orange, lemon and lime will not keep as long.
Patchouli is at the other extreme and actually gets better as it ages.
