Glass or Plastic: What’s best for Storing Essential Oils?


Essential oils are extracted from various types of plant. These are then distilled through water or steam, and infused with other ingredients. The concentrated liquids have numerous medicinal and aromatic properties, and are especially popular in the cosmetic industry. 

While companies continue to manufacture high quality essential oils, the question remains: how should they package their products?

How to Store Essential Oils

If you deal exclusively with “pure” essential oils, then you must use glass containers. Essential oils are quite potent, and storing them in glass bottles prevents packaging deterioration. Glass has an inert nature, and thus the oils do not react adversely with the containers as they would if they were made from plastic. A glass vial with an airtight lid is the perfect way to store pure essential oils.

When to Use Plastic

For diluted essential oils, plastic packaging may be used. However, don’t just use any kind of plastic for your product as the oils can still react with low quality plastic. Plastic PET or LDPE bottles are excellent for storing essential oils and can safely withstand their potency. These are especially popular for packaging lotions or liquids containing essential oils, where the oils have been diluted.
PET Plastic bottles are less expensive than glass vials, and are easier to carry. They weigh lower and are less likely to break upon impact than glass bottles. This makes them a good alternative to glass bottles for storing diluted essential oils. However, for more concentrated forms, glass vials must be used.

Essential Oils Bottle Sizes

Essential oils are usually bottled in sizes ranging from 5ml, 10ml, and 15ml.  They are also bottled in dram sizes, where 1dram is equivalent to 3.69ml. Some companies also have their products measured in drops and prefer dropper lids.
Here again the material of the dropper is of absolute essence as a plastic or rubber dropper will depreciate when exposed to the oil. For more potent essential oils, glass droppers are the recommended choice. 

It is important to acknowledge that essential oils are quite strong and potent substances, and may react differently to different packaging styles. It is recommended that you test your product on a set of sample bottles before finalizing your packaging choice.  This will ensure safe and efficient storage of essential oils and prolong their shelf life.
