Diluting Essential Oils

It's no secret that essential oils need to be diluted before using. Essential oils are extremely powerful, this is one reason we love them so much.

Diluting essential oils is the best practice to follow when applying your oils topically. A few drops really can go a long way when diluted.

Dilution is a needed step in oil safety. Using undiluted essential oils is a quick way to get sensitized or irritated skin. It is also a waste of precious oils and money. Not to mention that essential oils are way more effective when they are diluted in a carrier oil.

Any carrier oil can dilute essential oils, making them safe for topical use. Some favorites are jojoba, fractionated coconut oil, and rosehip oil.

Essential Oil Drops as a Measurement

What is an essential oil drop? It is important to remember that drops are frequently used when making essential oil recipes but they are not an exact measurement. A drop is considered an approximated unit of measure.

Drop sizes can vary based on the device used to dispense the drop, oil viscosity, and other factors. These two calculators are based on the common thought that 20 drops are in 1 ml.

While drops may not be an exact measurement, they are good guidelines for safely making essential oil blends. Use drops when making homemade recipes and blends for personal use or even gift-giving.

When creating large batch essential oil blends (like when making products in bulk to sell), weighing your blend out on a scale would be a more exact method and less tedious than counting out hundreds of drops. Some also prefer to measure in ml or teaspoons.

What Dilution Percentage Should I Use?

Here is a general guideline to go by for diluting essential oils. Keep in mind that some essential oils have maximum dermal levels for safe use so that would need to be considered.

0.5% - 1% Dilution For essential oils being applied on the face (facial tissue is more delicate), recommended at 1% or less dilution.
1% Dilution For children age 2+, pregnant or breastfeeding women, elderly, adults with sensitive skin.
2% Dilution For adults, children age 12+, daily use, great for massage oils, lotions and creams, long term issues.

3% - 5% Dilution

For spot treatments in roll ons, aches, bruising, congestion, and other temporary issues.
up to 10% Dilution For RARE short term only, used on specific areas when lower dilutions were not effective.
