In the upcoming section we will shed light on essential oils distillation & other extraction processes and products obtained by these approaches.
What Are Natural Essential Oils
Basically natural essential oils are hydrophobic liquids that have the volatile chemical compound. Natural essential oils are extracted from plants and their parts. These possesse the natural flavour or essence of its source plant. These are widely used in different industry verticals such as pharmaceuticals, cosmetics, beauty, food and beverages industries.
There are a number of essential oils including the clary sage, lavender, lemongrass, aniseed, begramond etc. Each and every essential oil has their own properties & characteristics. These natural oils have outstanding chemical constituents & medicinal properties. These include – analgesic, antiseptic, antibacterial, sedative, antimicrobial, anti-viral, and many more. Natural essential oils manufacturers in India work hard to keep the essence of plant & its parts so that these could be used for treating different kinds of ailments.

Natural Essential Oils Extraction : A Brief Intro
In the above section, we have discussed a little bit about natural essential oils. Now here we will talk about the different essential oils extraction methods.
Steam Distillation
Steam distillation is a widely used method for obtaining the essential oils. In this process, steam plays a significant role. First, it vaporizes the volatile compounds and after that it gets condensed. After this, it’s collected at the receiver in liquid form. In this process, dry steam is passed through the plant material. In the list of distilled essential oils – Amyris essential oil, bergamot natural blend essential oil, lavender etc. are popular one.
Let’s go through step by step of this process:-
- The raw material is taken into a container which is made up of stainless steel. It works as a closed environment.
- Now it’s time to inject the steam which will help to release the volatile essential oils.
- In the next stage, the hot vapor cools down after coming into contact with cold water.
- The mixture is collected in a separator.
- As water and oil do not mix, therefore it’s quite easy to collect the natural essential oil from the mixture.

Solvent Extraction
The solvent extraction process is the natural essential oils extraction process which is used for extraction of natural oils which are incapable to tolerate the high heat. Steam distillation is based on the application of heat, therefore Jasmine, Linden Blossom is not used for extraction through the steam distillation process.
The solvent extraction process is used for extracting the volatile oils from plants and its parts where the various solvent can be used for extraction. In the list of solvents hexane, ethanol, and other organic compounds are used for this purpose. In the perfume industry, the solvent extraction process is used. During this process, pigments and waxes are also.
In the first step, the plant material is dipped into the solvent.
- The mixture passed through several stages of the chemical process. Afterward, the mix which is called “concrete” is obtained
- In the next step, alcohol is added to concrete and heat is applied to the mixture.
- In this stage, oil particles get separated & collected via a condenser.
- The chemicals which were used in the solvent extraction process remain in the oil
- This final mixture is used by the perfume manufacturers.
Co2 Extraction
Co2 extraction process uses the Co2 for obtaining the natural product. It’s also known as the supercritical extraction process. In this process, none of the molecules get damaged because less heat or chemicals are used. The natural products obtained from this process are used in perfume making and aromatherapy. Basically, the products obtained through this process are higher in concentration and thicker. This process is mainly used at 95 to 100 F. In the list of Co2 extracts, we have a number of products such as – basil co2 extracts oils, bergamot co2 extracts, cinnamon co2 extract oils, Eucalyptus, Lavender Co2 extracts, Nutmeg co2 extracts and many more.
Now let’s see the steps of the Co2 Extraction process.
- First Place the raw material inside a chamber and then apply the pressurized Co2 which converts into the liquid form.
- Here it’s worth noting that Co2 works as a solvent that helps in extracting the volatile oils from the plant material.
- After this low pressure is applied that converts Co2 into the gaseous form which finally comes out of the chamber
- The final product that is obtained from this process contains the unaltered chemical composition.
Here it’s important to note that Co2 gas is colorless and odorless, therefore it’s easy to handle. As there is no use of harmful chemicals used during this process hence the natural products extracted from this process are safe for the environment as well as people.
Maceration
It’s a wonderful process for the extraction of natural products. The companies use this method over other extraction processes such as steam distillation or solvent extraction. Carrier oils are used as a solvent during this extraction process. In this process, the mixture of the dried plant material and oil is placed under gentle heat. After some time, the plant’s internal material (oil) comes out from the plant’s material. The extract contains the properties of plants. Let’s go through the step by step process of Maceration.
- First, take the grounded plant material into the vessel and then add solvent
- This solvent will work to soak out the essential oil compounds.
- Now leave this mixture for 1 week.
- Here it’s important to note that the liquid is strained from the vessels and then the solid residue is discarded from it.
- After this, we obtain a mix of expressed & strained liquid which is further filtered.
- At the last stage, we get the essential oil.
The color of the final product will change. It’s further will be poured in an airtight container and kept for almost 12 months. The rancid will emit a foul smell which is very strong. The oil obtained from this process is used in cosmetics.
Enfleurage
The Enfleurage method is one of the rarely used techniques these days. The fat works as a separator instead of a steam solvent or steam. Animal or plant fat can be used.
In this process, the fresh petals of flowers are placed over the top layer of fat. The fat is spread over a chassis. The fragrance of flowers seeps into the fat where this process can take 1-3 days. After this petals of flowers are replaced and repeated with another one. The alcohol can also be used for washing. Now dry it.
In fact, there are two types of processes such as hot and cold enfleurage processes. In the hot process, heated fat is used for increasing the action.
Cold- Pressed Extraction Technique
This is another popular way for the extraction of oils from plant’s seeds & their fruits. It’s a kind of mechanical process where a hydraulic press is used for extracting the internal content of the fruit and vegetable. It’s very advantageous as it retains all the flavor, aroma as well as nutritional value. A number of carrier oils are extracted from this process. Natural carrier oils manufacturers provide you an array of carrier oils such as Almond sweet refined carrier oil (Spain), Aloe vera oil, Argan carrier oil, camellia seed organic carrier oil, neem carrier oil, and many more.
