Mandarin essential oil: the gentlest citrus for the evening and for children

Sweet mandarin is the gentlest of the citrus oils and is not phototoxic. Dosage, blends, rules for children and storage.

In brief: Mandarin essential oil is cold-pressed from mandarin peel. It smells sweet, soft and slightly floral and is among the gentlest citrus oils: according to Tisserand & Young it is not phototoxic. For a diffuser 2–6 drops, on the body up to 2% (12 drops per 30 ml), for children from 2 years of age up to 1%.

Latin name	Citrus reticulata, for tangerine Citrus tangerina
Extraction	cold pressing of the peels, origin Italy
Main components	limonene 65–75%, γ-terpinene 16–22%, methyl N-methylanthranilate 0.3–0.7%
Dilution on the skin	adults 1–2% (6–12 drops per 30 ml), children 2–6 years 0.5–1%
Phototoxicity	no, you need not restrict your sun exposure
Shelf life	roughly 12 months from opening, best in the fridge

Mandarin is the citrus you reach for when orange seems too "juicy" and lemon too sharp. Its scent is sweet and round and has a floral undertone that makes it remind you more of a pastry shop than a fruit market. That is why it suits evening blends, a children's room (with regard to age) and winter spicy scents.

Below you will find what mandarin oil contains and why it is no problem in the sun, how many drops to put in a diffuser and on the skin, four blends with oils we have in stock, and where its limits lie. This is not medical advice.

What is in mandarin oil and why it smells different from orange

Most of the oil is limonene, as with all citrus oils from peel, but mandarin has less of it than orange and in addition contains around 16–22% γ-terpinene. The characteristic sweetness and floral note come from methyl N-methylanthranilate, a substance you also find in neroli. It makes up only up to 1%, but the nose recognises it at once, and under a UV lamp the oil fluoresces blue because of it.

Botanically it is a bit of a muddle. Mandarin is Citrus reticulata, tangerine (Citrus tangerina) is its close relative with a darker peel, and traders often interchange the names. The scent and safety differ only slightly. Some producers further distinguish green mandarin (from unripe fruit, sharper and fresher) and red (from ripe fruit, sweeter). Mandarin from Pěstík is pressed from ripe peels and has a sweet profile.

Is mandarin phototoxic?

No. Both the Tisserand Institute and the review by Dosoky and Setzer class pressed mandarin among the citrus oils that are not phototoxic, like sweet orange. It contains furocoumarins, which burn in the sun, only in traces.

IFRA does restrict methyl N-methylanthranilate to 0.1% in cosmetics that stay on the skin, but when mandarin is diluted to 2%, the finished blend contains roughly 0.006–0.014% of it, well below the limit. Beware of the difference with another oil: petitgrain mandarin from the leaves has much more of this substance and is phototoxic. Pěstík does not sell that one.

Citrus	Phototoxic pressed oil?	Limit on sun-exposed skin (IFRA)
Mandarin	no	no limit
Sweet orange	no	no limit
Grapefruit	slightly	4%
Lemon	yes	2%
Lime	yes	0.7%
Bergamot	yes, strongly	0.4%

How many drops and where

We count 1 ml ≈ 20 drops. Mandarin is gentle, and in a diffuser you can tolerate it even at a higher dose than mint or eucalyptus. A detailed table by device and room size can be found in the article how many drops of essential oil to put in a diffuser.

Diffuser: 2–4 drops for a room of 10–15 m², 4–6 drops for a living room.
Aroma lamp: 3–5 drops in the water.
Face: 1%, that is 2 drops per 10 ml of carrier oil.
Body and massage: 2%, that is 4 drops per 10 ml or 12 drops per 30 ml.
Bath: 3–5 drops mixed into a spoonful of carrier oil or cream, and only then into the water.

Blends with mandarin

Evening calm (diffuser)

3 drops of mandarin, 2 drops of lavender. The simplest evening blend, which smells sweet, not soapy. More tips for the evening are in the article essential oils for relaxation and sleep.

Winter punch (aroma lamp)

4 drops of mandarin, 1 drop of cinnamon, 1 drop of ginger. Mandarin takes the sharp edges off the spices. Do not use cinnamon on the skin; it irritates strongly.

Soft floral (diffuser)

3 drops of mandarin, 1 drop of neroli, 1 drop of chamomile. Neroli and mandarin share the same sweet component, so together they hold the blend.

Massage oil (2%)

Pour 30 ml of jojoba oil into a dark bottle.
Add 7 drops of mandarin, 3 drops of lavender and 2 drops of frankincense, 12 drops in total.
Close it, mix by turning it upside down and label it with the date.
Test on the forearm and wait 24 hours.
Use up within 2–3 months.

Mandarin and children

In aromatherapy mandarin is traditionally cited as one of the most suitable oils for families, because it is gentle and does not contain 1,8-cineole like eucalyptus or rosemary. The age limits apply to it too, however. According to our article essential oils and children:

Age	Diffuser	On the skin
under 3 months	nothing	nothing
3–6 months	no citrus (only lavender or chamomile, 1 drop)	nothing
6 months to 2 years	1 drop of mandarin, briefly	no
2–6 years	1–3 drops, 10–20 minutes	0.5–1%, that is 1–2 drops per 10 ml
from 6 years	as adults, shorter sessions	up to 1%

Never drip oil on a child's pillow or on hands from which they may put it in their mouth or eyes. Keep the bottle out of reach.

Traditional use and research

Mandarin is traditionally used in blends for calming and a better mood, and it is popular in natural cosmetics for its sweet scent. Laboratory studies describe antioxidant and antimicrobial activity of mandarin oil, but these are experiments outside the human body. We do not promise that the oil will help with sleep or stretch marks, as is sometimes written. It is not taken internally.

What to watch out for

Oxidation: limonene and γ-terpinene age in air, and oxidised oil can cause an allergy. Close the bottle right after use, store it in a cool place (in the fridge is fine), and a year after opening use up what remains in the diffuser.
Cats: citrus oils harm cats, because their liver cannot break them down well. Run the diffuser only where the cat can leave, and put nothing on fur. More in the article essential oils and pets.
Pregnancy: mandarin is not among the oils to avoid in pregnancy. Stick, however, to a dilution of up to 1%.
Sensitive skin: always a patch test on the forearm, never undiluted.

How to recognise a quality mandarin oil

On the label, look for the Latin name (Citrus reticulata or Citrus tangerina), the method of extraction (cold pressing) and the country of origin. The oil should be yellow-orange to orange, in dark glass and without a sharp turpentine scent. Cheap "mandarin fragrances" without a Latin name tend to be synthetic perfumery. If you like sharper citrus, take a look at lemon oil, which is, however, phototoxic.

Frequently asked questions

Is mandarin oil phototoxic?

Pressed mandarin oil is not phototoxic, and you need not restrict your sun exposure after using it. A different oil, petitgrain mandarin from the leaves, is phototoxic. At the usual dilution of up to 2%, mandarin is safe even on exposed skin.

Is mandarin suitable for children?

It is among the gentlest oils, but age limits apply to it too: in a diffuser from 6 months, on the skin from 2 years of age and at a dilution of 0.5–1%. No oils under 3 months.

What is the difference between mandarin and orange?

Mandarin has less limonene and in addition methyl N-methylanthranilate, which gives it a sweet, slightly floral note. Orange smells brighter and more like fresh juice. Both have similar safety, and neither is phototoxic.

What should mandarin oil be combined with?

Best with lavender, chamomile and neroli for the evening, with cinnamon, ginger or clove in winter blends, and with frankincense or cedar in a massage oil.

How should mandarin oil be stored?

In a dark, well-closed bottle in a cool place, ideally in the fridge. Once opened it lasts roughly a year, after which it oxidises and no longer belongs on the skin.
