Essential Therapeutics Chesty Diffuser Blend 15ml

A Guide to Essential Oil Dilutions

If you measure your essential oils in drops be warned that not all “drops” are the same!
There are a variety of “dropper inserts” for essential oil bottles in the marketplace. Depending on the size of the aperture, the drop size can vary widely, from 18 drops to 40 drops per 1ml. Hence, a recipe that calls for 10 drops of essential oil in 10ml of a vegetable oil can vary from about 5.5% to 2.5% in concentration of essential oil – quite a difference.
The pharmaceutical drop dispensers that we use for Essential Therapeutics essential oils dispense on average: 32 drops per 1ml.
Disposable measuring plastic pipettes and standard glass eye droppers also generally give this approximate drop size.
To work out percentages, a small calculator is very useful.
Say you wish to make a 2.5% concentration of essential oils in 20ml of Essential Base Cream or Lotion. How many drops of oil should you add?
With your calculator: 20 (ml of Base Cream or Lotion) times 2.5 (then press the % key) equals 0.5. This means 0.5ml of essential oil needs to be added to the cream of lotion. There are 32 drops in 1ml, so 32 times 0.5 (ml) equals 16.  16 drops of oil is required.

A simple guide for essential oil dilutions:

For an approximately 0.5% concentration of essential oils in a carrier base use: 4 drops of essential oil per 25ml of carrier

For 1.0 %: 3 drops of essential oil per 10ml of carrier

For 1.5%: 4 drops of essential oil per 10ml of carrier

For 2.5%: 8 drops of essential oil per 10ml of carrier

For 5%: 17 drops of essential oil per 10ml of carrier

For 10%: 35 drops of essential oil per 10ml of carrier

In terms of the weight of essential oils, at 32 drops being 1ml of oil, each drop weighs approximately 25mg (milligrams)
