Laboratory Testing

Purity and Highest Quality Available.

Good Thyme oils quality assurance is the highest in the industry. Before we sell you or your family any essential oil, Good Thyme Oils does everything within our power to establish and confirm that our oils are 100% pure, natural, and of the highest quality. To ensure that each of our essential oils meets the strictest standards, and the highest reputable laboratories.


Testing the oils.


1. Each oil is organoleptically tested upon arrival at Good Thyme oil's facility. The quality team evaluates each essential oil to make sure it meets Good Thyme Oils high quality standards. Organoleptic testing means taste, sight, touch, and smell.  The essential oil is then placed on a sterile laboratory testing strip. It's allowed to evaporate over a period time.  It takes approximately 30 to 40 minutes for the essential oil characteristics to evaporate. What is left on the strip is very telling--the color, aroma, the consistency, and overall look of the oil. If there is any discrepancy to what high-quality oils look or smell like, you know immediately that there is a problem with the oil.



2. Following the Organoleptically test, the sample of the essential oils is sent for testing to one of our high standard third-party testing laboratories. At the laboratory, the oil will undergo multiple tests including GS "Gas Chromatography" and MS "Mass Spectrometer" testing

contaminants or adulterants that will show up during these tests. If any synthetic markers show up from the test, the essential oil will be sent  back for more in-depth testing. A test called a "chiral analysis" is used find out if it in fact natural or synthetic additions have been made.


3. Another test we employ is microbial testing involves testing a sample of essential oils for the presence of bio microorganisms that are harmful. These  microorganisms might be  fungi, bacteria, viruses, and or different types of mold. The process for testing  involves taking a sample of the essential oil, adding it to an agar testing plate, and placing it into an incubator for 24 to 48 hours. After the sample has had sufficient time to grow, the sample is then observed through several visual tests.  This test is done to ensure that no bio microorganisms are present or have been introduced into the oil during any of the processes.


Even though we've tested and repeatably tested the essential oils, Good Thyme Oils cares about our customers and if we say on our label that our  essential oils are 100% pure, that is what we have promised to give to our customers.
