Essential Oil Dilution Calculator
Get the right number of essential oil drops for a safe and effective dilution. Pick your carrier oil amount, target dilution percentage, and how many essential oils you are blending. The calculator handles the math and gives you a safety note for your chosen concentration.
The dilution formula:
Essential Oil (mL) = Dilution% x Carrier Oil (mL) / (100 - Dilution%)
Then convert mL to drops: Drops = mL / drop size (typically 0.05 mL per drop, or 20 drops per mL)
Recommended dilution rates:
- 0.5% -- infants (6+ months), elderly, facial skincare
- 1% -- children ages 2-12, sensitive skin, daily facial blends
- 2% -- standard adult dilution for everyday body oils, lotions, and massage
- 3% -- acute issues, short-term use (muscle soreness, cold relief)
- 5% -- very targeted, short-term applications only
- 10%+ -- rarely recommended outside clinical aromatherapy
Common carrier oils:
- Jojoba -- closest to skin's natural oils, long shelf life
- Sweet almond -- light, affordable, great for massage
- Coconut (fractionated) -- odorless, stays liquid, very light
- Grapeseed -- light, slightly astringent, good for oily skin
