Mixing and Blending Essential Oils
Mixing and blending essential oils is a personal and creative art. It is not an exact science. There are, however, suggestions that are very beneficial in the mixing and blending that will aid you in finding the perfect blend for your needs.
When searching for a therapeutic blend it is important to use essential oils with the desired properties and characteristics. For example for inflamation, you might consider Lavender for its anti-inflammatory properties, as well as Melaleuca (Tea Tree) oil which is also an anti-inflammatory oil. A blend of the two together is more effective.
Also the essential oil intensity isconsidered in the blending of two or more essential oils. The essential oil intensity refers to the odor or aroma of an essential oil. When blending an oil with a high odor intensity and one with a low odor intensity, the high intensity oil if not used sparingly will overpower the oil with a low odor intensity. More of the oil with the low odor intensity will need to be added in order to be noticed. Your preference and the oils properties will be the deciding choice.
There are no hard and fast rules of mixing and blending. I use oils whose odors I am drawn to, but have the properties that I am looking for. So experiment with the oils until you find the combination that works for you.
I have included several base oils and carrier oils along with their properties to guide you in choosing the ones most appropriate for your needs, and a chart of suggested amounts of essential oils to add to the base oils. There is also information included about some of the essential oils and the rating of odor intensity and evaporation rate, which is called the essential oil note. I will add to that information as I continue my research.
The evaporation rates vary considerable with the various essential oils. They are given in terms of top, middle and base notes for use in blending purposes. The classification of notes will also overlap at times. It seems to depend upon the seasonal variation in the crops. The top notes are noticed first in a blend as they evaporate more quickly. The base notes are the slowestto evaporate. They help in making the blend’s aroma last longer. The middle notes are the ones that help hold the entire range of scents together. They have a balancing quality.
The odor intensity of essential oils is rated low, medium, high, very high and extremely high. These ratings describe how powerful the odor of an essential oil is.
Extremely high indicates the most dominating essential oil and can easily overpower the blend if not used sparingly. Very high is also a strong odor, but a little less that the extremely high rating. The high rating is slightly less than the very high, whereas the middle rating is a bit lower that the high rating. The medium rating falls somewhere in the middle range of evaporation, and the low rating reflects a softer, gentler scent. The scent of this essential oil will be lost if not adjusted and taken into account when used with higher rated essential oils. As you work with the essential oils, you will become more adept at knowing the difference.
I am listing many (not all) of the essential oils along with their odor intensity and evaporation rates to aid you in adjusting the amounts accordingly when mixing and blending the essential oils with the base and carrier oils.
Basil- high odor intensity and top note
Bergamot – low odor intensity and top evaporation note
Cedarwood - low odor intensity and base note
Chamomile - very high odor and middle note
Clary Sage – medium odor intensity and middle note
Eucalyptus – very high odor intensity and top note
Frankincense – very high odor intensity and middle/base note
Geranium - high odor intensity and middle note
Ginger – medium odor intensity and middle note
Grapefruit – very high odor intensity and top evaporation note
Hyssop – high odor intensity and middle note
Juniper – medium odor intensity and middle note
Lavender – low odor intensity and middle/top note
Lemon – very high odor intensity and top note
Lemongrass - medium odor intensity and top note
Mandarin – high odor intensity and top note
Marjoram – medium odor intensity and middle note
Melaleuca (Tea Tree) – very high intensity and top note
Myrrh – very high odor intensity and base note
Patchouly – medium odor intensity and base note
Peppermint – high odor intensity and top note
Petitgrain – medium odor intensity and middle/top note
Rosemary – high odor intensity and middle note
Sandalwood – base note
Ylang – Ylang – high odor intensity and middle/base
The popular base and carrier oils are Apricot Kernel oil, Avocado Pear oil, Borage Seed oil, Castor oil, Cocoa Butter, Corn oil, Extra Virgin Olive oil, Evening Primrose oil, Grapeseed oil, Hazelnut oil, Jojoba oil, Peanut oil, Safflower oil, Sesame oil, Soy oil, Sunflower oil, Sweet Almond oil, and Wheatgerm oil. To learn about the properties of these oils and carriers, refer to the section on Base and Carrier Oils.
Vitamin E – It not only helps prevent oxidation, but helps to heal scar tissue, and helps to prevent aging by rejuvenating skin cellular activity. Cut the end off the vitamin E capsule and squeeze the oil out. I generally use 400 IU for 1 ounce of base oil. Other antioxidants are Evening Primrose, Jojoba, and Wheatgerm. You can learn more about these in the section Base and Carrier Oils.
This is a suggested mixing chart. I mix at least 1 oz and often 2 oz at a time. Essential oils need to be stored in containers that will not let the light penetrate. Small brown or dark blue bottles in various ounce sizes may be purchase at health food stores or ordered on line. It will save time if you know the size of the container before mixing your essential oil blends. The oils should be kept in a dark dry area, as light and moisture affect the quality of the essential oils.
1. Add the essential oils to your container
2. Add the antioxidant (optional)
3. Add any other ingredient that has the properties desired. (Optional)
4. Fill the bottle up with the base oil. (If you know the size of the container, otherwise measure)

This is a suggested mixing chart. You may find that you need to vary from this chart. I usually add 15 drops of combined essential oils to 1 oz and 30 drops of combined essential oils to 2 oz. You will want to experiment to see what works best for you.
Here is an additional chart that you will find useful from time to time
