You Need To Know Before Buying Essential Oils
Today, how are essential oils produced?
- Carbon dioxide extraction Critical fluid extraction (SFE) uses carbon dioxide (sCO2), which is in the critical state and capable of being both environmentally safe and environmentally acceptable solvent. Other toxins such as hexane.
- Distillation begins with boiling water vapor with biomass. (Lavender, sandalwood, cinnamon, etc.), when they become weak, they become volatile organic compounds (VOCs). (Like fat / hydrophobic) will pass through the condenser, with steam disintegrating from the parent biomass. In the condenser, the steam will cool down and the components will break apart when in the pipe. Water is separated from the oil and left, but Hydro Salts (Distilled water vapor of flowers) with essential oils.
- Extraction using fat. Oriflora or fat-based extracts are used for fragile flowers such as jasmine and are currently rare in the production process. This process takes several weeks and requires animal fat to absorb the essential oils from the flowers. The result is a fat/oil or polyamide mixture to wash the alcohol to get rid of the fat.
- This compression process is reserved for fruit peels. Compression machine (Or cold extraction) will juice from the fruit bark and distill it. The smell is likely to change from the very old and the properties in the treatment are very different.
- Solvent extraction Fluid extraction is commonly used for flowers with low aromatic oils such as roses, jasmine, mimosa, and so on. We can extract more essential oils by using petroleum ether or chemical solvents such as ethanol. And Hensen or any other safer way, and start as popular as carbon dioxide extraction. Solvent extracts are fatty substances similar to wax, also known as concrete. When the concrete is washed with alcohol, the fat will break off, and the rest will consist of volatile and non-volatile forms.
What kind of aroma is right for you?
The results of lipid extraction and solvent extraction are essential oils of concentrated plant species, which are widely used in perfumery and cosmetics. Including medical treatment with aromatherapy. These essential oils are extracted from real flowers such as rose, jasmine, and vanilla.
- Carbon dioxide extraction
It is said that this method is quite popular in the field of aromatherapy, which is different from the extraction by distillation. The plant components are extracted and do not require harmful solvents. Popular flavors include cannabis, turmeric, and vanilla.
- Essential oils (compressed)
Compressed orange juice is different from extraction by distillation, such as darker colors, resulting in stained clothing. And the smell is more like orange peels. Technically, orange peels are not essential oils, as they contain non-volatile components, but in the aromatherapy industry, chemistry is an exception.
- Essential Oils (Refined)
The chemical properties of essential oils extracted by distillation are often different from the original. You should note that the ingredients in the bottles are distilled. Otherwise, you may not know what the product is and the essential oil!
This method is popular because it retains the same chemical properties of essential oils. For example, cinnamon, cloves, ginger, lime, mandarin, orange, peppermint, rose, spearmint, vanilla, and mulberry were extracted using non-alcoholic solvents such as glycerin and vinegar.
- Hydro Salts
Hydrolysis is a very rare and very fragile essential oil. Can be used in combination with mineral water, perfume, and skin care products. Should be used immediately or refrigerated because the bacteria can grow faster and rancid. Examples in this article are commonly found in the market include lavender, orange blossom, roman chamomile, and roses.
- Aromatic oil
This is the result of soaking the aromatic plants in the oil for several days or weeks. The remaining oil is what our ancestors used as a perfume, anointing oil or wax used in healing.
- Using Alcohol Solution
This is the use of alcohol or tincture as the main solvent to extract essential oils from plants. The tincture has long been used in medicine. They are easy to use and require only 80-90% vodka, herbicides, spoon and soak for about 2 months. Examples include arginine, St. John’s, garlic and exchequer.
