An essential oil dilution chart can be helpful when blending aromatherapy products.
A typical way to dilute essential oil is in a vegetable carrier oil, such as almond, argan, coconut, grapeseed, jojoba, or olive. To dilute essential oils, drop them into a bottle or other container and then add the carrier oil. Close the container. Shake gently.
However, you can also use other carriers such as cocoa butter, shea butter, and other cosmetic butters. Typically, you need to melt the butter and stir in essential oils. Follow the instructions for the aromatherapy recipe you are making.
For most purposes, recommended dilution is 1% (for children and
sensitive individuals) to 3%. Stronger dilutions are occasionally used
for specific purposes. A common, but by no means universal, suggestion
is:
- For facial applications: 1% or less dilution
- For massages oils and other leave-on body products: 2% dilution
- For rinse-off bath and body products: 3% dilution
Generally, for essential oils that are safe for children under age 2 years, use a dilution of 0.5% or less.
You
need to know about the essential oils you are using. Some strong
essential oils have lower recommended dilutions. Best source for this information is Essential Oil Safety, 2nd Edition.
Recommendations may also be different for pregnancy or people who have a medical condition. If in doubt, consult a professional.
