Essential Oil: Dilution Chart
Also filed inEducation

Essential oils are very concentrated and need to be diluted in order to use them safely. Learn how to dilute essential oils properly for adults and kids.
Essential oils are very powerful substances that can be used to improve sleep, skin and even boost the immune system. We use them for cleaning, soap making, and in some of our favorite cooking dishes.
Therefore, it is very important to dilute them properly before use. Essential oils are natural aromatic compounds that are steam distilled from plants or cold-pressed from the peels of plants. They are very helpful for so many things, but at the same time, extremely potent.
They are very concentrated and a little goes a long way! With the proper dilution, we can even use essential oils for our kids.
HOW TO DILUTE ESSENTIAL OILS
Do your research and make sure the essential oils you use are pure will no adders or fillers. It is extremely important to note that there are a TON of different essential oil companies out there with a wide price range. The FDA does not regulate essential oils and as a result, manufacturers do not have to disclose the purity.
Essential oils can be diluted in a carrier oil, shampoo, lotion, salve, or serum. The easiest way to dilute essential oils is by making a roller bottle. To make a roller bottle, you need a roller bottle, carrier oil, and essential oils.
WHAT IS A CARRIER OIL
Any vegetable-based oil or animal fat can be used to dilute essential oils, here is a list of the top carrier oils for essential oils:
- Coconut oil
- Fractionated coconut oil
- Jojoba oil
- Sweet almond oil
- Rosehip oil
- Avocado oil
- Argan oil
- Grapeseed oil
- Olive oil

ESSENTIAL OIL DILUTION RATIO CHART
You will need to dilute essential oils differently depending on skin type and age. For younger children, we dilute the essential oils more than we would for an adult.
HOW TO DILUTE ESSENTIAL OILS IN A 10ML ROLLER BOTTLE
- Newborn-6 months: 1-2 drops
- 6 months- 2 years: 1-3 drops
- 2 -5 years: 2-5 drops
- 5-12 years: 5-10 drops
- 13 and up: 15-20 drops
Most roller bottles are 10mL; if you have a smaller roller bottle, be sure to adjust the above chart properly.

HOW TO DILUTE ESSENTIAL OILS IN A DIFFUSER
Use the chart below in conjunction with your specific diffuser.
- 100mL: 3-5 drops
- 200mL: 6-10 drops
- 300mL: 11-15 drops
- 400mL: 16-20 drops
- 500mL: 21-25 drops
DILUTING ESSENTIAL OILS IN SHAMPOO
To receive the benefits of essential oils in your hair, you can either make your own homemade shampoo or add essential oils to your conventional shampoo. For shampoo, it is recommended that you dilute the oils by 2.5%. This would be about 2-3 drops of essential oils to an ounce of shampoo.
If you add essential oils to a child’s shampoo, you should dilute the oils by .5-1%. This would be about no more than 1 drop of essential oil to one ounce of shampoo.
DILUTING ESSENTIAL OILS IN LOTIONS

If you want to make a massaging lotion or simply use essential oils to cover a larger surface area, it may be best to add the oils to a lotion. You can make your own lotion, like our homemade shea butter lotion, or you can add essential oils to a lotion you already have at home. It is best to dilute the essential oils between 1-5 drops per oz of lotion.
This would mean that you should not add more than 10 drops of essential oils to 1 teaspoon of lotion. If making an essential oil lotion for a child, dilute it further to make it a 1-2% dilution.
HOW TO MAKE ROLLER BOTTLE BLENDS FOR KIDS

A common question we get from our readers is how to make a roller bottle blend for kids. Most recipes have several different essential oils in them; however, it is only recommended to use 2-3 drops of oil total in the roller bottle.
Then dip a toothpick into an essential oil and then swirl it into your carrier oil. This is where the “toothpick drop” comes in handy. This idea allows you to use more essential oils without exceeding the recommended amounts. To start off, fill a 10mL roller bottle with a preferred carrier oil.
The toothpick will transfer less than a drop of essential oil into the roller bottle so that you can use several essential oils in one blend.
Always consult with your doctor before using any essential oils on kids.
MIXING ESSENTIAL OILS WITH WATER
We all know that water and oils do not mix; however, if you use a natural emulsifier, you can mix them. We make a lot of DIYs with oil and water, such as homemade febreze and linen sprays. If we shake the bottle right before misting it into the air, it does work.
We also like to add a drop of citrus essential oil to our drinking water for added flavor and benefits. If using essential oils internally in water, it is recommended to use 1 drop of oil to 4 ounces of liquid.
Although we personally think it tastes a little too strong. We add no more than 1 drop to a whole glass. It is not recommended for children under the age of 12 to ingest essential oils.
If you ever have a skin reaction to an essential oil that was applied topically, it is best to rub the area with a carrier oil instead of water. The water can cause the reaction to worsen, and a carrier oil can soothe the irritation.
DILUTING HOT ESSENTIAL OILS
Some essential oils are considered hot oils. These oils should never touch the skin without being diluted, as they can burn the skin.
Hot essential oils:
- Arborvitae
- Basil
- Bergamot
- Cassia
- Oregano
- Clove
- Cinnamon
- Ginger
When we am using these essential oils we will dilute them further to avoid skin irritations.
CAN YOU APPLY ESSENTIAL OIL UNDILUTED?
There are some essential oils known as “neat” oils. Neat oils are ones that you can apply to the skin without being diluted.
We always recommend diluting any essential oil before applying it, even if it is a neat oil. We know lots of people who do not have any issues with applying neat oils.
However, if you do decide to apply neat oils directly to the skin, test a small area of skin first just to be safe.
Neat essential oils:
- Cardamon
- Copaiba
- Frankincense
- Jasmine
- Lavender
- Roman Chamomile
- Rose
These essential oils are gentle and would be great to use with kids, diluted of course.
DILUTING ESSENTIAL OILS FOR SENSITIVE SKIN
If you are using essential oils on sensitive skin, then you should dilute them further. It is recommended to dilute essential oils 1-2% when using them on someone with sensitive skin or on an area of the body that is more sensitive.
If you are using an essential oil for the first time, you should test a small area on the back of your hand or on the bottom of the foot as that area is less sensitive than other areas. It is not recommended to use essential oils near the eyes, inside the ears, or inside the nose.
