What is the shelf life of your products?

Essential Oils: Approximately 2 years, depending on how you store them. Optimal storage conditions and exposure to oxygen will have an effect on that timeline. Pure essential oils do not go rancid. Over time, however, essential oils can oxidize, deteriorate and gradually lose their therapeutic value and aromatic quality. Some essential oils have longer shelf life.

Guidelines from Robert Tisserand:

Aromatherapy pioneer, essential oil expert, and Essential Oil Safety author Robert Tisserand provides an easy-to-remember rule of thumb for determining the shelf life of your essential oils. He recommends storing your essential oils in the refrigerator and bases these guidelines on proper care and cold storage (halve these guidelines for oils not stored in a refrigerator):

  • 1-2 Years: Citrus, Neroli, Lemongrass, Frankincense, Tea Tree, Pine and Spruce Oils
    (i.e. Oils that contain monoterpenes, particularly limonene, are more prone to oxidation. The more monoterpenes an oil contains, the shorter its shelf life. Most citrus peel essential oils, except Bergamot, consist of 90% or more monoterpenes, and thus are oils that have the shortest shelf life. Other oils that generally consist of over 80% monoterpenes include Angelica Root, Cypress, Frankincense, Pine and Spruce oils.)

  • 2-3 Years: Most All Other Essential Oils
    (i.e. Oils that contain a higher percentage of aldehydes, oxides, monoterpenols, esters, ethers, phenols or ketones.)

  • 4-8 Years: Sandalwood, Vetiver, Patchouli
    (i.e. Oils that contain a high percentage of sesquiterpenes and/or sesquiterpenols have the longest shelf life. Although the aromatic quality of these oils may improve over time, their therapeutic quality can still diminish. Thus for therapeutic use, it may be wise to use within the lower threshold of 4 years. Other oils that contain a significant percentage of sesquiterpenes and/or sesquiterpenols include Copaiba Balsam, Gurjun Balsam and Myrrh. Some Cedarwood distillations have higher sesquiterpene concentrations.)

Carrier Oils: Approximately 1 year, depending on how you store them. Some carrier oils have longer shelf life. Optimal storage conditions and exposure to oxygen will have an effect on that timeline.
