π‘ How to blend safely
Dilution % = essential oil volume Γ· (carrier oil volume + essential oil volume) Γ 100. A standard dropper delivers about 20 drops per ml. Add the essential oil first, then top up with carrier oil, shake well, and let the blend rest 24 hours before use. Essential oils are highly concentrated plant extracts β applying them undiluted can irritate or sensitize skin. Keep face blends at 1% or below, and consult a professional before use during pregnancy, with children, or if you have skin conditions.
β FAQ
What is the essential oil dilution formula?
Essential oil volume (ml) = carrier oil volume (ml) Γ dilution % Γ· 100. For example, 30 ml of carrier at 2% needs 30 Γ 0.02 = 0.6 ml of essential oil, about 12 drops at 20 drops/ml. Dilution % is the essential oil share of the final blend.
What dilution should I use for different parts of the body?
0.5% for children and sensitive skin, 1% for the adult face, 2% for adult body massage, 3% for local soreness, 5% for short-term acute care, and 10% only for short-term targeted use with professional guidance. Higher concentrations carry a higher irritation risk.
How many drops are in 1 ml of essential oil?
A standard dropper bottle gives about 20 drops per ml, though 15-25 drops is possible depending on the dropper, oil viscosity, and temperature. This tool uses the industry-standard 20 drops per ml.
