Surveys have shown that even many fragrance lovers can hardly distinguish the pure, natural fragrances from the synthetic and nature-identical “twins” from the laboratory. Many people are not aware that lilies of the valley and lilac are not able to produce any essential oil and therefore no natural fragrance. What is offered on the shelves of tea shops and supermarkets are often purely synthetic or nature-identical creations from the laboratory.
Nature identical is not natural
Here, the word “nature-identical” serves to give the consumer the impression that the corresponding fragrance is just like nature – but that’s not true at all. In contrast to essential oils, which are known to have been used by our ancestors in all conceivable applications and have been proven for millennia, there are no empirical long-term studies for the synthetic and nature-identical cocktails.
A study by the University of Witten / Herdecke, commissioned by the BDIH, reveals the difference in the allergic potential of natural fragrances and their nature-identical twins. Tests with fragrance-mix allergic subjects examined the effect of natural lemon oil compared to chemically pure citral, which was recreated as the main ingredient contained naturally in citrus oil.
Higher allergy potential of synthetic and nature-identical fragrances
The result clearly shows the allergic potential: Over 90% of the allergically sensitive persons react to synthetic citral, but not even 3% to natural lemon oil. Therefore fragrance does not always mean the same: Only with accordingly excellent and pure natural essential oils you can be sure that you hold a natural product in your hands.
But even with natural essential oils, there are still big differences in quality. The quality of an essential oil is influenced by several factors that are not always obvious to the consumer when buying.
