Dilution Rates

Below are some simple measurement equations and an approximate amount of essential oils to be used by adults with normal skin.  Realize that oils have differing levels of scent intensity.  For example, lavender is light and airy whereas patchouli is deep and heavy.  Start with a lower amount of the essential oil, you can always add more. This will save you from having to throw out a great concoction because its scent takes over your space!

A Standard drop= 1/20 to 1/30 milliliter, depending on the density* of the oil. The measurements below are based upon the 1/20 of a milliliter drop size and American fluid ounces.

All the measurements given are by liquid volume with the exception of the kilo. Kilos and pounds are weight measurements and therefore the liquid volume ranges according to the specific gravity** of the essential oil.

Generally speaking, the thicker the oil, the heavier it is, so, for example, a kilo of Castor oil will take up less space in a bottle than Grapeseed oil.

To make your life easier when counting drops, may we suggest using 6”, 3.5 ml, graduated measure disposable plastic pipettes available through us or your essential oil provider.

*Density: A scientific term for the result of dividing mass (how much) by volume (how big).  In the context of using Essential and Carrier oils, you could boil it down to a simple “how thick is it?”!

**Specific Gravity: Another scientific term. For our purposes it is in essence the same as density.

Essential Oil Dilution Ratios

This table shows the total number of drops to use in your dilutions.  When using this table, be aware that if you slip and add a drop more than the formula states, just move on – all is NOT lost, you haven’t ruined anything!  This isn’t nearly as fiddly as baking!  HAVE FUN!
