PURE ESSENTIAL OILS PASS THE STRICTEST TEST
GC-MS TESTING: (Gas Chromatography–Mass Spectrometry) Checks the purity and potency of the oil against thousands of compounds. HEAVY METAL/PESTICIDE/HERBICIDE TESTING: Makes sure all PURE Essential Oils are free of heavy metals, pesticides, and herbicides. OPTICAL ROTATION: Measures the molecular structure of the oil to confirm there are no synthetic compounds. SPECIFIC GRAVITY TESTING: Measures how heavy (dense) the oil is compared to water. FLASH POINT TESTING: Measures the combustible “flash” temperature of the essential oil.
CHIRALITY TESTING: Ensures no synthetic elements are present.
ORGANOLEPTIC TESTING: Expert distillers evaluate the smell, colour, and consistency of each oil before any other tests are conducted.
REFRACTIVE INDEX TESTING: Measures the density of the oil using a concentrated beam of light. This verifies the potency of the oil.
MICROBIAL TESTING: Makes sure oils contain no traces of microorganisms such as fungi, bacteria, pathogens, or mold.
ISOTOPIC ANALYSIS: Breaks oils down to the atomic level to find out which isotopes are present in an essential oil and at what amounts - this is another way to triple-check the potency and quality of the oil.
Without a central certification body, we turn to the International Organisation for Standardization (ISO) and Association Française de Normalisation (AFNOR) for reputable quality specifications available for many essential oils. When an ISO or AFNOR standard is not available, we compare our oils to historical testing data from essential oils experts to ensure PURE Essential Oils are always the highest purity and quality oils available.
