Enter the volume of essential oil and carrier oil into the calculator to determine the ratio of essential oil to carrier oil. This calculator can also evaluate any of the variables given the others are known.

## Essential Oil To Carrier Oil Ratio Formula

The following formula is used to calculate the essential oil to carrier oil ratio.

R = (E / C) * 100

Variables:

• R is the ratio of essential oil to carrier oil (%) E is the volume of essential oil (ml) C is the volume of carrier oil (ml)

To calculate the essential oil to carrier oil ratio, divide the volume of essential oil by the volume of carrier oil. Multiply the result by 100 to get the ratio in percentage.

## What is an Essential Oil To Carrier Oil Ratio?

An Essential Oil to Carrier Oil Ratio refers to the amount of essential oil that is diluted in a carrier oil for safe application on the skin. Essential oils are highly concentrated and can cause irritation or adverse reactions if applied directly to the skin. Therefore, they are mixed with carrier oils, which are mild and non-irritating, like coconut oil, jojoba oil, or almond oil. The ratio can vary depending on the specific essential oil and the intended use, but a common guideline is to use a 2% dilution for adults, which equates to about 12 drops of essential oil per one ounce of carrier oil.

## How to Calculate Essential Oil To Carrier Oil Ratio?

The following steps outline how to calculate the Essential Oil to Carrier Oil Ratio.

1. First, determine the volume of essential oil (E) in milliliters (ml).
2. Next, determine the volume of carrier oil (C) in milliliters (ml).
3. Next, use the formula R = (E / C) * 100 to calculate the ratio of essential oil to carrier oil.
4. Finally, express the ratio as a percentage (%).
5. After inserting the values for E and C into the formula and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Volume of essential oil (E) = 5 ml

Volume of carrier oil (C) = 20 ml
