Most essential oils are quite ‘thin’ – they drip easily from their bottle. Others are quite thick, viscous like honey, and that can make them clog up diffusers and difficult to mix in blends or dilute. Vetiver is a great example of a thick oil. Many absolutes (‘essential oils’ extracted by alcohol methods rather than steam distilled) can also be very thick.
Diluting thick essential oils
One way to work with these thick essential oils is to dilute them in alcohol-based diluents rather than carrier oils. An example is to use witch hazel as the diluent to be able to make a spray.
Heating thick essential oils
Another method is to heat the thick essential oil. The risk with using heat is that it can break down or change the chemical components of essential oils, which leads to them no longer having the same therapeutic effects or the chemicals can become more toxic.
To avoid over-heating, a gentle heat can be applied for a short period. One way to achieve this is called the Rice Method. Microwave a cup of dry rice for one minute and mix so that it is warmth is even throughout the container. Push the essential oil bottle into the warm rise and leave there for a minute or so. The oil should then be less viscous and easier to drip.
Water Bath Method
Alternatively, the Water Bath Method works by warming a small bowl of water, and placing the essential oil bottle in the water. This method can ruin bottle labels, though.
It can help to also warm the carrier oil to help with the mixing.
We hope you can apply these ideas and you enjoy working with the thick essential oils.
