What essential oil should I use in my diffuser?


Essential Oils have many properties effective in diffusion and there is no danger of addiction, so enjoy!

The various effects and properties:

antimicrobial and antiviral: they can attack microbes and powerful viruses and also destroy them as well as stop their proliferation

ex: oregano, eucalyptus

antifungal: they prevent or treat infections due to microscopic fungi

ex: palmarosa, geranium

antiseptic et purifying: they disinfect by destroying germs, sanitizing and deodorising the air

ex: lemon, cajuput


A few ideas for creating an ambience:

You are ready to invent your own mixture? Here are a few basic principles to help you compose a harmonious odour for diffusion or other uses (massaging oils or perfume for example).


The different fragrance notes

Fragrances are classified into three large “notes”: the basis notes, the heart notes and the headnotes.

The headnotes

A headnote is quickly diffused and can be perceived very quickly but it will fade within 15 minutes.

These are the essences of zests or plants with a citrus odour as well as the pines that produce refreshing and stimulating odours

ex.: lemon, mandarin, orange, grapefruit, bergamot, Pinus sylvestris, lemongrass, eucalyptus globulus.

The heart notes

The heart note (molecules with average volatility) intervenes in a second phase and gives balance to the fragrance. It takes over to retain the freshness of the headnotes and announce the warmth of the base notes.

Here we find the essential oils of flowers or herbs. This note rounds off the mixture and gives a floral fragrance if accentuated.

ex: chamomile, true lavender, geranium, rose, petitgrain bigarade, ylang-ylang, linalol thyme, eucalyptus citriodora et eucalyptus radiata, palmarosa.

Basis notes

The basis note or bottom note comes into the air slowly and will remain there for a long time. It is the note that arrives last and stays the longest. It is the note that reaches the olfactive level last but that gives structure to the perfume.

Generally, they correspond to resins and woods, but some can be found in entire plants. These create warm and sensuous scents if accentuated. Beware however to not use a heavy hand with them.

ex. frankincense, cedarwood, rosemary, patchouli, cloves, cinnamon, vetiver, ravintsara, clary sage, sandalwood, vanilla, juniper, saro.


ratio The right proportions

Basis note: 1 part // Heart note: 2 parts // Headnote: 7 parts

10% of EO for mixtures using an oil base for the skin

5% of EO for mixtures using an alcohol base for the home or to spray on clothes

pyramide olfactive

precautionsCare to be taken

Not all EO are good for diffusion. Indeed, some of them may be irritating (even harmful) or just too thick for optimal diffusion.

Essential oils with ketones or phenols

Do not diffuse pure in the air EO containing ketones or phenols as they can provoke irritation of the respiratory tract. ex. clove, cinnamon leaf, rosemary camphor, spike lavender, peppermint

Beware of EO containing esters

Do not inhale or diffuse in the air, EO that contain esters such as chavicol methyl (ex. basil or fennel) either hot or cold.

Diffusion in the presence of children or pregnant women

Many EO are not suitable in the presence of children or pregnant women. Seek the advice of an aromatherapist. In any case, you should never diffuse EO in a room where there is a baby or a child. They should enter a room only 10 minutes after the end of a diffusion.

Precautions in the case of disease

People who are asthmatics, epileptics, allergic to camphor or who have a tendency to both hypertension or hypotension, must be very careful in their choice of EO used. Sylvestre pine is forbidden for people suffering from hypertension. Eucalyptus radiata and wild marjoram are forbidden in the case of asthma or epilepsy.
