Carrier oils also called base or fixed oils; they play a vital role in aromatherapy. Essential oils are so potent, and most often, they need dilution to use them safely.

Although, this doesn’t mean that carrier oils’ only purpose is to dilute essential oils. That would be a false statement. They are highly nutritional and beneficial for humans, and carrier oils have a variety of uses. 

For our purposes, let’s focus on the use of carrier oils in aromatherapy and start by the dilution rates right away. To safely use essential oils in healthy adults, a %2 dilution rate is needed. For kids and other risk groups, %1 or even less dilution rate would be optimum.

Let’s say that you are preparing a simple hair serum by using rosemary oil for yourself. If you are targeting a %2 dilution rate, that means for a 10 ml base oil; you need only six drops of essential oil. For larger amounts, you can just multiply and re-calculate how many drops needed to dilute your E.O safely.

What is a Carrier Oil?


They are called carrier oils because they carry essential oils. These oils are vegetable oils extracted from the high oil content plant seeds, kernels, and fruits. In contrast, essential oils are derived from the aromatic parts of the plants. Since the yield is lower essential oils are much costly than carrier oils.

Most of the fixed oils are not so potent, and they have a nutty smell and a taste. If you suspect a bitter taste or odor in base oils, most likely that oil has been spoiled. In essential oils, we talk about oxidization rather than rotting. This is bad because it means the therapeutic properties have long been gone.
