Aromatic blending is an excellent way to get the most out of your oils for everyday use. You can create blends as perfumes or for therapeutic uses. The essential oil chart below provides you with the number of drops you need to get started for bottles of 5ml to 25ml. It is important to note that some essential oils have greater viscosity than others. For example, myrrh and vetiver oils are thicker than wild orange and bergamot oils. The thickness or viscosity of an oil can increase or decrease the amount of drops needed, therefore a good rule of thumb is to use fewer drops for the thicker oils.
1 ml = 20 drops
1 teaspoon = 100 drops
1 ounce = 600 drops
1/2 ounce = 15 ml
2/3ounce = 20 ml
5/6 ounce = 25ml
1 ounce = 30 ml
How To Calculate Dilutions
You’re creating an essential oil blend using Lavender and Melaleuca in a 10ml bottle and you want a 20% dilution. Using the chart provided you can see that a 20% dilution for a 10ml bottle requires 40 drops of essential oils. You can split the amount of drops you want to use for each of the three oils as you see best fit. Here’s an example of how to calculate the dilution per drop.
10 ml = 200 drops
20% of 200 drops = 40 drops
Add 40 drops of essential oil to your carrier blend.
In this example, we’ll use a 10% dilution in a 15ml bottle.
15ml = 300 drops
10% of 300 drops = 30 drops
Add 30 drops of essential oil to your carrier blend.
Dilutions for Massage
Typically for a massage oil blend, I recommend using a 1-2% dilution. This will give the client enough of the benefits of the oils to promote a relaxing effect. If you have a client with a specific issue like joint discomfort, muscle tension, or achy muscles, you can use a stronger dilution with oils that assist with these health concerns.
Dilutions for Adults: 2 – 25%
Dilutions for Infants and Children: 0.25% – 1%
