Dilution of EOs

Just came across a helpful chart in's free Intro course that I wanted to save for future reference. It's vital to dilute most oils before application to keep from irritating the skin.

(Guess you can see which of my interests has got most of my time these days... I am severely neglecting that little Etsy shop.)

Amount of carrier by weight Number of drops of essential oil
  1% dilution 2% dilution 3% dilution
1 oz 5-6 drops 10-12 drops 15-18 drops
2 oz 10-12 drops 20-24 drops 30-36 drops

The next obvious question is, how do you choose which dilution to use?
1% Dilution — Used for children under 12, and seniors over 65, pregnant women and people with long-term illnesses or immune systems disorders. A 1% dilution is also a good place to start with individuals who are generally sensitive to fragrances, chemicals or other environmental pollutants.
2% Dilution — Use for general health supporting blends for skin care, for natural perfumes, bath oils, and for blends you like to use everyday.
3% Dilution — Use this dilution when creating a blend for a specific, acute health concern, such as pain relief or getting a cold or flu.

When making larger quantities of blends such as 3 oz and above, you can begin by using less essential oil than suggested above, and see if that works. We find that we don’t need to keep doubling the amounts as we make larger quantity blends in order for them to be effective.

I broke these down for smaller amounts below:
1% dilution: 2-3 drops/tablespoon; 1 drop per 1/6 oz of carrier
2% dilution: 5-6 drops/tablespoon; 2 drops per 1/6 oz of carrier
3% dilution: 7.5-9 drops/tablespoon; 3 drops per 1/6 oz of carrier
(Possible volume equivalent: If 1 oz carrier = 2 Tablespoons, 1/6 oz = 1 teaspoon)
