Essential Oils are the 'essence' of plants and plant parts. The essential oil contains many medicinal, aromatic and flavor related properties of the plant or plant parts from which it is extracted. Which is why essential oils find a variety of medicinal, wellness, beauty and aroma uses. Some of the popular essential oils are Tea Tree oil, Lavender oil, Eucalyptus Oil, Lemongrass oil while there are hundreds of essential oils being used throughout the world.
Essentials Oils are generally extracted by the process of distillation from the plant and in some cases use other methods of extraction as well like expression extraction, cold pressing, solvent extraction, wax embedding, resin tapping etc. Essential oils find use in a variety of ways. Different essential oils find their use in the following popular ways
- For use as a beauty ingredient for several DIY recipes for skin and hair care
- For use in specific skin and hair related issues and diseases
- As an ingredient in commercially manufactured beauty products
- For use in fragrances
- For use in aromatherapy at home, office or in spas
- For use in home cleaning, insect repelling etc.
All these uses need different and appropriate recipes and dilution. Pure essential oils are a highly concentrated form of the extract and hence are very potent. They cannot be used without dilution. If the usage is topical, one needs to prepare a really diluted solution with a suitable medium, usually a base oil like coconut oil, castor oil, almond oil, sesame oil, olive oil etc (also called carrier oils). Improper use of essential oils may trigger allergic reactions, skin irritation and even worse reactions. Also, generally speaking, essential oils should not be consumed internally nor by children, pets, pregnant and nursing mothers or by people undergoing serious a medical issue or treatment.
Read on to understand the way to dilute different essential oils for different purposes.
Do All Essential Oils Needs to be Diluted?
Essential Oils are highly concentrated extracts, so it is necessary to dilute them before use. Essential oils are usually used in the following ways and in a diluted manner in each of these cases:
- Topical regular use for skin, hair & scalp.
- Topical use for a particular pain point/concern area e.g. a joint pain or a concentrated infection of the skin.
- Home Use as Diffuser
- Home Use as Cleaner, Spray etc.
Regular topical use is most diluted whereas a short-term use on a small area of concern can have a slightly higher concentration. Non-topical use can have a slightly higher concentration too e.g. uses for home fragrance, cleaning/disinfecting or use for insect repelling etc.

- 1 teaspoon is 5mL
- 1 tablespoon is 15 mL
- 30 ml is equal to 1 ounce
- 6 teaspoons are equal to 1 ounce
- 2 tablespoons are equal to 1 ounce
How to Calculate the Number of Drops needed for any Dilution%?
It's a simple calculation. For an example:
If you need 1% essential oil dilution in one teaspoon carrier oil, remember that one teaspoon is approximately 5mL. Which means essential oil needed would be 1% of 5mL = 0.05mL.
We know that each drop is equal to 0.05mL. Which means you need one drop of essential oil in 1 teaspoon carrier oil to make a 1% dilution.
Use the conversion table mentioned in the previous section to calculate for any dilution requirement.

There are several kinds of home diffusers for home or office or indoor spaces. Many of them operate using water and do not need a carrier oil at all. Some of those operate using heat and oil.
