3C standard newspaper
Good essential oils also have 3C standards. For example, imported essential oil must have a certificate of origin, customs declaration and China inspection and quarantine. The certificate of origin shows that the essential oil comes from a reliable place of origin. The customs declaration certificate proves that the essential oil comes from legal channels, not smuggled products. China inspection and quarantine certificate is the most important proof that its bacteria and heavy metals are not over standard and its products are harmless. Without this certificate, it means that essential oil is not a safe product and will be harmful to human body. So when choosing essential oil, be sure to ask if there is enough proof. If there is no definite proof, then you can't choose.
price
Essential oil is the essence extracted from plants. It takes many plants to extract a small bottle, such as rose essential oil. Generally, it takes 3,000 ~ 5,000 kg of rose petals to extract 1 kg of essential oil, and its price is naturally high. Some fruit essential oils are relatively cheap, but they are not cheap either. So don't believe that you can buy real essential oil at a low price by buying essential oil. Fake essential oils are generally synthetic, adding a lot of chemical spices, which is very harmful to the body.
standard
The international standard specification of unilateral essential oil is 10 ml. Generally, the specifications above 20 ml are very rare, so when buying, if the quantity is relatively large, you must be cautious. Some limited edition or extremely expensive essential oils, with smaller specifications, 8 ml and 5 ml, such as sandalwood essential oil.
parcel
The packaging of essential oil must be in dark glass bottles, because light, temperature and humidity will destroy the quality of essential oil. Generally, there are three kinds of glass bottles containing essential oil: dark blue, dark green and amber. If it's not glass bottles of these colors, be careful. There must be a safety dropper at the mouth of the essential oil bottle, because the amount of essential oil is measured by "drops", so the safety dropper can control the amount. If the bottle of essential oil is transparent, plastic, with a big mouth and a rubber dropper on the head, this essential oil is very unprofessional, so you must be careful when choosing it.
situation
Although essential oil is called "oil", most essential oils are not greasy, but like clear and transparent water. To test whether essential oil contains grease, we can use the volatility of essential oil to test. Drop 1 drop of essential oil on white paper. After volatilization, pure essential oils will generally not leave oil stains, but the iron-containing essential oil may be slightly turbid, and some citrus essential oils will leave yellowish traces. After the fake essential oil volatilizes, it will leave obvious oil traces.
penetrability
The permeability of essential oil is super strong, and this feature can also identify its authenticity. If you put a drop of real essential oil on the back of your hand and massage it gently, it will be absorbed quickly and will not produce greasy feeling. The fake essential oil cannot be fully absorbed after the same amount of application and massage for a long time, or the skin is very greasy.
smell
The real essential oil is extracted from plants and has the concentrated smell of the original plants. So the smell is natural and persistent. It won't get tired of smelling it for a long time. No, the smell of pure essential oils is generally short-lived, it will be pungent, and it will be a headache after a long time.
point out
The skin will be different in each period, so when choosing essential oil, you should choose the one that suits you according to the characteristics of your skin. reference data
