One of the demands of Aromatherapy is to use pure essential oils to achieve the maximum therapeutic effect. However, for the purpose of the sellers’ profit, sometimes oil is not guarantees 100% pure when it is sold to customers. Oil adulteration alters the ingredients and reduce therapeutic effects. The essential oil therapy (aroma therapist) believes that essential oils contain “life energy” or “essence” of the plants, and have many components that nowadays, scientists are not determined and prepared for. These components make the uniqueness of each individual essential oil. Oil industry lacks of strict regulations. Consequently, it forces the consumers to use their knowledges and experiences to check and ensure that they had purchased pure oil resources.
With large quantity of oil, the examination is very simple. However, for the consumers who buy small quantities for individual use, it is largely based on experience or may require the sellers to provide information about quality testing of the oil. Therefore, how to detect adulteration of oil is important and this article will give you some advices.
No matter how subtle and difficult to detect the adulteration can be, there are still some signs if observant consumers can identify:
The oil viscosity:
The viscosity is defined as the resistance of the flow. Sandalwood essential oil is an ideal example. If the viscosity makes us feel tough when getting a small drop of oil out of the bottle, it is surely good quality oil. If you think that oil is opaque as well as the viscosity is erratically changed, the quality of the oil is changed. If the viscosity is increased, it means the oil is oxidized and “aging”.
Drop oil on the blotter:
To check that whether the essential oils have been adulterated with the others (for instance: the vegetable oils) or not, we can drop oil on cloth or paper towels. If the oil is adulterated, it will bring up a “circle of grease” after the oil has evaporated. On the contrary, the pure essential oils often evaporate completely without leaving any trace.
The scent of essential oil:
If customers get acquainted with almost scents of authentic essential oil and can recognize them, it is very helpful for the consumers to discover the sort of oil adulteration.
The essential oil price:
Price which is an indirect sign shows the quality of the oil. For example, the rose oil is one of the best essential oils with a high price. So if you buy it cheaply, you should consider whether its quality is guaranteed or not.
Oil adulteration is rampant in the essential oil industry. The mixing can be done by using the plants or with plants or other synthetic substances … Of course, this will lead to many negative effects as well as safety issues when using the product. With those tips above, hope you make the right decision when choosing an essential oil for yourself.
