Top Essential Oil Brands: Tested for Purity

Are you using adulterated essential oils?

Testing Essential Oils

First, lets start with what adulteration means. Adulteration in this case is the addition of substances to essential oils. This makes them not pure, and not how nature intended.

An example of this would be the addition of linalool to lavender oil. This linalool can be either natural or synthetically made. As linalool is cheaper than lavender oil, adding additional linalool to lavender lowers the cost of the product and raises profit margins for manufacturers or essential oil companies.

Adulteration can occur at the manufacturing level or they can by adulterated by the company buying from the manufacturer. This is one reason why its important for essential oil companies to test every batch of oil that is purchased, and for responsible companies to have the testing data available to the public.

However, just because an essential oil is GC/MS tested, does not necessarily mean they are not being adulterated. Figuring out if an oil is adulterated is complex, and requires skill.

10 Company's Essential Oils were tested for Adulteration

Unlabeled samples were sent to the Aromatic Plant Research Center for professional testing. All the testing and research done on these companies were done by Consumers Advocate.

Below is an infograph for the test results for lavender and peppermint essential oils from 10 companies.

2 Things to Consider When Buying Essential Oils:

1. Buy quality products from a reputable source.

 These products will not be the cheapest on the market, but also note that MLM structured businesses will be overpriced. Does the company specialize in selling essential oils? This is a good indication that they take the time to source quality essential oils from sustainable suppliers.

2. Believe in the ethics of the company.

Do they source their ingredients responsibly? Are they environmentally friendly? Do they teach knowledgeable and safe usage of their products? (You can reference the websites below to determine whether they provide accurate safety and safety information about their essential oils)
