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.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ R = \left(\frac{2}{100}\right) \times 100 = 2 \% \]

The Essential Oil to Carrier Oil Ratio is 2%.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ R = \left(\frac{5}{200}\right) \times 100 = 2.5 \% \]

The Essential Oil to Carrier Oil Ratio is 2.5%.
