Our products may indeed have variations in their aromas from one batch to another but always remain, with respect to their formula and the biochemical components present naturally in the essential oils which make them up, within the standard variations accepted both by our quality control and by the standards in force (Afnor, European Pharmacopoeia etc.).
Our essential oils are 100% natural, 100% pure and non-rectified vegetable substances. The composition of the aromatic molecules of essential oils depends on environmental factors such as weather and geographical conditions (sunlight, moisture, exposure, altitude, soil type etc.).
The essential oils used by Puressentiel are selected on the basis of criteria linked to their biochemical composition and not solely for their olfactory notes.
Therefore, each of our products made up of blends of several essential oils may present perceptible olfactory differences but with no modification of its intrinsic properties. These olfactory variations are above all a guarantee of the quality of a product that is of 100% pure and natural origin.
