怎样辨别精油真假

10种简单有效的鉴别方法

1、看价格
植物精油主要采用蒸馏法提取，一般100公斤的花草可提炼出2~3公斤精油，因此真正的精油价格不会太便宜，市场的参考价格是：普通精油如香橙、茶树油大概10m/400-1300元，名贵精油如檀香大约10m/900-1700元。建议大家到正规大型的商场或专业美容机构购买。如果一些自称是进口的精油，价位却比国产货还便宜的话，其真假自然就不言而喻了。

2、看用法
除了玫瑰、茶树、熏衣草等少数品种，绝大多数纯精油是不可直接用于皮肤的，否则会造成灼伤、脱皮，如果商家介绍给你的精油说可以直接用于皮肤，还说是纯精油，那就有问题了。一定要分清基础油和精油的不同，有些打着精油名义的基础油的确蒙骗了不少的人。

3、闻味道
多数纯精油味道柔和醇正，因为是{bfb}从植物中提取的，所以纯正的精油都有一种难以言喻的自然植物的味道（虽然气味不一定好闻），用香精调配的精油味道略刺鼻，长期使用这样的精油有百害而无一利。刚入鼻时味道不是很冲，但有回味，到后脑时会有一种旷野的感觉。每个人对他的感觉也不尽相同，它的前味、中味、后味各不相同。

4、点薰
A、将单方精油点熏几次后，如果留下油腻的残留物（不同于水垢）说明用植物油或矿物油稀释过；如果残留下结晶体，则很可能是用乙醇、乙醚稀释过，带给人们的危害是不言而喻的。
B、取一杯清水，滴入一滴精油，真正的纯精油一般挥发速度较快，之后没有任何残留，若用植物油或矿物油稀释过，挥发速度会缓慢的多，水面上往往留下油渍。

5、看包装
精油通常会保存到深色密封小玻璃瓶里，有特殊的耐强酸，强碱的瓶盖，防止日光及氧气渗入，这样精油才不易挥发、变质。在良好的保存环境下（保存在常温下），通常可以保存两年，品质好的精油可保存4-5年。柑橘类精油也可保存1-2年，用配有滴头的瓶子包装的产品一般是3%-10%之间的稀释精油，不是纯精油。纯植物精油的标签上是应标明纯度的。

6、看比重
一般来说，草类精油的比重是最轻的，滴入一杯水中会快速散开，水面会呈现浮油状态；树脂类精油分子最重，滴入一杯水中，可整滴完整的落入杯底，不宜溶于水。但这两者会在水面下，会分布两种比重的精油分子，虽不溶，但未到已弥漫整杯水了。花类精油中比较特殊的洋柑橘，比重也比水重，不溶于水，与树脂类精油类似，会整滴直入水底，看得出晶莹剔透的墨绿色精油珠。

7、看颜色
例如德国洋柑橘，因为含有相当珍贵的成分“蓝经”，它的颜色是深蓝色的，有浓厚的药味。如果你买到的是无色的那一定是上当了！

8、看质地
品质越精纯的精油，渗透力越强。将测试的精油轻擦在手背或手腕内侧，再用指尖稍微xx几下。品质好的精油会在瞬间被吸收，而且不会在皮肤上留下亮晶晶的油脂成分。也可以观擦精油中是否含有杂质。比如传统的冷冻压榨法从果皮中压出的精油，其中会留下少许的残渣，这会使产品品质不佳。由于分子结构的原因精油的挥发速度比较快，在5-10分内挥发挥，说明比较纯正。挥发的很慢也不一定是纯正的精油。

9、看融合度
品质纯正的精油亲油性很强，调配在基础油内时，将xx融合，两者分子也xx结合。否则，便是精油含有化学合成品或蜡质，以至于不能与基础油充分融合。

10、看产地
萃取精油的植物，会因产地不同而品质有差异。土地的质量、气温、湿度和种植的水准、收成的时间和处理的方法等，都直接影响到其精油品质的优劣。所以选择精油时应该注意该植物的产地。（列一些精油的产地，如玫瑰精油是保加利亚的等）

How to distinguish between true and false oil

10 kinds of simple and effective method of identifying

1, to see the price
Mainly essential oils distillation, 100 kg of flowers generally can be extracted from 2 to 3 kg of oil, the real oil price is not too cheap, the market reference price is: ordinary essential oils such as orange, tea tree oil is probably 10m/400 -1,300 dollars, expensive oils such as sandalwood about 10m/900-1700 dollars. Recommend you to the formal beauty of large shopping centers or professional organizations to purchase. If some claim to oil imports, prices cheaper than those made in China if its true or natural self-explanatory.

2, see usage
In addition to rose, tea tree, lavender and a few varieties, most pure essential oils can not be directly used for the skin, or cause burns, peeling, if the business introduced to you the essential oils that can be directly applied to the skin, said that it was pure essential oil, then there is a problem. Must distinguish between the different base oils and essential oils, some of the name name of oil base oil did fool many people.

3, smell taste
Most pure essential oil flavor soft and mellow, because it is {bfb} extracted from plants, so a kind of pure essential oils have the amazing natural taste of the plant (although the smell is not necessarily good news), the deployment of essential oils with fragrance slightly pungent taste, long-term use of such oils are harmful to profits. When the newly recruited taste is not very red nose, but memorable, to the brain there will be a kind of wilderness feel. Everyone feels he’s not the same, it is the first taste, the flavor, after taste different.

4, point Kaoru
A, the unilateral oil point smoked a few times, if the oily residue left behind (other than scale) shows with vegetable oil or mineral oil diluted; if left under the crystal, it is likely that ethanol, ethyl ether diluted bring It is self-evident harm.
B, take a glass of water, drip a drop of essential oil, pure essential oils general essential real fast, then there is no residue, if the use of vegetable oil or mineral oil dilution, evaporation rate will slow more, the water often leaves oil stains.

5, see Package
Essential oils are usually stored in dark sealed small glass bottles with special resistance to acids, alkalis of the cap, to prevent the penetration of sunlight and oxygen, so that only less volatile oils, metamorphism. Kept in good conditions (stored at room temperature), can usually be kept for two years, good quality essential oils can be stored 4-5 years. Citrus essential oil also can be stored 1-2 years, with a dripper bottle packaging with the product is generally between 3% -10% dilution of essential oils, not pure essential oils. Pure essential oils should be marked on the label on the purity.

6, see the proportion of
In general, the proportion of grass essential oil is the lightest, and drops a glass of water will quickly disperse, the water will show oil slick state; resin essential oil the most important elements, drops a glass of water droplets can be integrated into the whole cup the end, not soluble in water. But both will be underwater, the proportion of the essential oil would be distributed two kinds of molecules, though not dissolved, but a full glass of water until they have been filled. Comparison of flower essential oil in particular foreign citrus, the proportion is also heavier than water and insoluble in water, and resin oils like, will the entire drop straight into the water, and can see crystal clear dark green oil beads.

7, see color
For example, the German foreign citrus, very valuable because it contains ingredients “Blue through” its color is dark blue, has a strong 药味. If you buy a colorless that must be fools!

8, see texture
The more pure quality essential oils, penetration of the stronger. Will test the oil in the back of the hand or wrist graze the inside, and then a little massage with a few fingers. Good quality oil will be absorbed in the moment and will not leave skin shining in the oil composition. Essential oils can also rub in view of whether it contains impurities. The traditional method such as pressing frozen out from the peel oil pressure, which will leave little residue, which makes product quality is poor. As the molecular structure of the causes of the volatile oil faster, play in the 5-10 fair share command, indicating relatively pure. Evaporation is very slow is not necessarily a pure essential oil.

9, see confluence
Hydrophobic quality pure essential oils are highly deployment within the base oil, it will be fully integrated, the two elements are fully integrated. Otherwise, that is, chemical compounds containing essential oils or waxes, so that can not be fully integrated with the base oil.

10, see origin
Extraction of essential oils of plants, because of the quality of different origin differ. The quality of land, air temperature, humidity and plant level, harvest time and processing methods, have a direct impact on the quality of its pros and cons of essential oils. So, choose essential oils should pay attention to the origin of the plant. (Out the origin of some essential oils such as rose oil is Bulgaria, etc.)
