▼Essential Oil Dilution Chart & Calculator: Safe Ratios Guide
Essential oils are powerful. Just one drop of peppermint oil is equivalent to 28 cups of peppermint tea. While this potency is great for wellness, applying it undiluted can damage your skin.
Whether you are filling a 10mL rollerball for headaches or mixing a 100mL body oil, getting the math right is crucial. This guide provides a free Dilution Calculator and a printable Reference Chart to help you blend safely every time.

Why You Should Always Dilute
Diluting doesn't make the oil "weaker" in effect; it makes it safer and smarter.
- 🛡️ Prevents Sensitization: Undiluted oils can cause chemical burns or long-term allergies.
- 💧 Better Absorption: Carrier oils (like Jojoba) help the volatile essential oils absorb into the skin before they evaporate.
- 💰 Saves Money: A 10mL bottle of essential oil can last for months when diluted properly.
