What is mandarin essential oil?

EFSA's panel defines expressed mandarin oil as "obtained by cold expression from the fruit peel of Citrus reticulata Blanco" and describes two colour types, green (green to green-brown) and red (orange to red-amber) (EFSA FEEDAP Panel, 2021). Its marker ranges are limonene 65 to 80% and gamma-terpinene 13 to 22% of the GC area, for a specification the panel wrote for one use. Our oil is sold neat, with the botanical name Citrus reticulata, cold-pressed from the fresh peel. The certificate we publish for one batch lists appearance "Green liquid". See what mandarin oil is for the full definition.

Is mandarin oil the same as tangerine or orange oil?

No, though they are relatives. A 2017 PLoS One study describes mandarin as C. reticulata Blanco, notes that Webber grouped mandarin genotypes in 1943 as king, satsuma, mandarin and tangerine, calls clementine "in fact a tangor", and puts the contribution of C. maxima to sweet orange at 41% (Oueslati et al., 2017). So tangerine is a group within the mandarin family and sweet orange is a different, hybrid-origin species. The oils differ in chemistry as well; Lu and colleagues found cold-pressed limonene at 74.93% in Ponkan mandarin against 85.50% in Valencia orange (Lu et al., 2019). Our shop FAQ says Citrus reticulata is a different citrus fruit from sweet orange. Orange oil is a separate comparison. Detail on tangerine is in the tangerine comparison.

How is mandarin oil made?

By expression, not distillation. EFSA describes water sprayed over the fruit to collect the released oil, the suspension filtered to remove cell debris, and centrifugation to separate oil from water. Our sourcing page describes a juice-line route and says the pressing happens at the extractors, not by us, so we say "cold-pressed" and never "we press". A 2026 review says pressing is described as preserving heat-sensitive volatile compounds, though it gives no composition data comparing pressing with distillation for this oil (Zhang et al., 2026). Read how it is made for the steps.

How much mandarin oil should I put in a carrier for skin?

Our shop's guidance is 0.5% to 2% in a carrier oil with a patch test first, roughly 3 to 12 drops per ounce, starting at the low end if you are new to citrus oils. The Tisserand Institute gives 1 to 3% for body oils and lotions and 0.2 to 1% for sensitive or reaction-prone skin (Tisserand Institute, dilution). We do not call 2% safe: we have no IFRA certificate for our oil, so no outside limit can be calculated for it. Weigh the oil for small batches, because a dropper cannot land on 0.5% in a 10 ml jar.

Is mandarin oil safe to wear in the sun?

Our shop page gives no sun warning, so it does not answer this. The Tisserand Institute lists expressed mandarin and tangerine among oils with extremely small amounts of furanocoumarins, not enough to be phototoxic, and says IFRA tells makers not to use citrus oils in leave-on products where bergapten is above 15 ppm (Tisserand Institute, phototoxicity). That statement is general to expressed mandarin oil, and the certificate we publish has no furanocoumarin figure, so we do not make the claim for our bottle. Distilled citrus oils differ from expressed ones. Distilled and expressed oils are not interchangeable for sun questions, so check which one a label describes.

Is mandarin oil safe in pregnancy, or around children and pets?

No source we read says it is, and our disclaimer tells anyone pregnant, nursing or with a medical condition to consult a physician. Our shop says to keep the oil away from eyes, children and pets. Tisserand's retail site advises a well-ventilated room for diffusing, caution around pets, and a minimum of diffusing in homes with cats (Tisserand FAQ). For what the authorities say about pregnancy, read the pregnancy article; the decision belongs to your midwife or obstetric clinician, and for a pet, your veterinarian.

Can I swallow mandarin oil?

Our shop says the oil is not for internal use. The Tisserand FAQ states that essential oils should never be swallowed or used in food and that doing so is potentially very hazardous. If you need to know what an ingestion listing covers, see the ingestion article, and ask a physician or poison control.

How long does mandarin oil last, and how should I store it?

We give no shelf-life number for our oil. The Tisserand Institute says most essential oils keep well for at least 1 to 2 years before oxidation takes effect, that heat, light and moisture speed oxidation, that more air in the bottle speeds it, and that refrigeration about doubles useful life (Tisserand Institute, oxidized oils). It is general to essential oils, not to ours. Our shop's line is to buy small, reorder often, and keep the bottle tightly capped in a cool, dark place. See how to store mandarin oil.

Does mandarin oil have proven health benefits?

No. A 2026 review of the oil describes the evidence as predominantly in vitro with some animal and computer-model work, and the 2026 review we read from a second group cites no human clinical trial (Castro et al., 2026; Zhang et al., 2026). We make no medical claim for our oil. Each claim is traced to its study in the benefit-claims article.

What does the mandarin oil certificate show?

The certificate we publish covers one batch (MANLUCCRBRC003A): botanical name Citrus reticulata, parts used peel, extraction cold pressed, appearance green liquid, relative density 0.852, refractive index 1.471 and optical rotation +69.80 degrees at 20 C. EFSA's ranges at 20 C are density 0.844 to 0.859 and refractive index 1.470 to 1.480, so the first two constants sit inside them. It shows no composition, no origin and no furanocoumarin or residue data, and its best-by date, 11/14/2025, has passed. If you need a GC-MS or residue report, ask in writing and get the answer in writing. Our COA guide reads it line by line.

Mandarin Essential Oil FAQ: Your Questions Answered

Ask five people what mandarin oil is and you will hear five answers: it is tangerine, it is orange, it is the one in the kids' room, it is basically lemon with the volume turned down. Here are the questions that sit behind most of those answers, with the plain version first and the source where one matters.

Is it the same as tangerine or sweet orange oil?

Mandarin and tangerine are close relatives. Citrus researchers have long grouped the mandarin family into subgroups (king, satsuma, mandarin and tangerine), and both oils carry the botanical name Citrus reticulata. Sweet orange is a different story: it is a hybrid with a good deal of pummelo in its ancestry. Our guide to mandarin versus tangerine goes through the overlap.

How is it made?

Ours is cold-pressed from the peel, not distilled. The oil sits in tiny glands in the outer skin of the fruit, and mechanical pressing releases it without steam. We buy it from the extractors that do the pressing, so what we do is select it, and we sell it neat and unblended. The full walk-through is in how mandarin oil is made.

What does it smell like?

Sweet, mellow and juicy, with a faint floral hum and an orange-blossom tinge. It is the softest of the common citrus oils, without the sharp edge of lemon. If you want the full tour, the scent profile has it.

How much goes on skin?

Our guidance is to dilute to 0.5% to 2% in a carrier oil and patch test first, which works out to roughly 3 to 12 drops per ounce of carrier. We start at the low end, and we would stay there for the face. For comparison, the Tisserand Institute lists 1 to 3% for body oils and lotions and 0.2 to 1% for reaction-prone skin. Nobody should treat 2% as a universal green light, so begin small and build only if you want to. The details are in our dilution and patch test guide.

What about sun?

Expressed (pressed) mandarin and tangerine oils are listed by the Tisserand Institute among citrus oils with extremely small amounts of furanocoumarins, not enough to make them phototoxic. That is a statement about the category. We do not have furanocoumarin data for our own bottle, so if you will be in strong sun or on a sunbed, a wash-off product or an evening routine is the easy choice.

Can I use it in pregnancy, around children or pets?

That is a conversation for your midwife, pediatrician or veterinarian, because the published guidance is thin and varies by situation. We sell an external cosmetic oil, keep it out of reach of children and pets, and have written up what authorities say in our pregnancy article.

Can I swallow it?

No. It is a concentrated aromatic material for external and aroma use, and Tisserand says essential oils should never be swallowed or used in food. The ingestion article explains what an ingestion listing does and does not cover.

How long does it keep?

Pressed citrus oils are mostly limonene, which reacts with air, so freshness matters more than a number on a label. Tisserand says most essential oils keep well for at least one to two years and that refrigeration about doubles that. Our habit is simple: buy a size you will finish, keep it tightly capped, cool and dark, and reorder when you are low.

How should I smell it before I use it?

Put a drop on a paper strip rather than sniffing straight from the bottle. Hold it at arm's length and bring it closer slowly. You'll notice the first impression is sweet and juicy, and that a floral shading shows up a little later as the brightness fades. Smelling it this way tells you far more than a quick whiff from the neck of the bottle.

What is a good first project?

Something small. A few drops in a diffuser, or a little linen spray, is an easy way to meet the scent without committing to anything. If you would like to try a diluted body oil or a bath oil, mix a small amount and patch test first. We sell the mandarin only, so a carrier oil, a spray bottle or a diffuser comes from a craft shop, pharmacy or grocery.

Does the colour matter?

Mandarin oils come in different shades, and the certificate we publish describes our batch as a green liquid. A shade is a type label rather than a score, so if a bottle looks different from one you had before, treat it as a reason to ask a question and not as a verdict.

Does it have health benefits?

We make no medical claims. A 2026 review of the oil describes research that is mostly laboratory and animal work, which is interesting chemistry but not a promise about what a bottle does for you. We sell it for its aroma and for scenting your own cosmetic projects.

What does your certificate of analysis show?

The certificate we publish covers one batch: relative density 0.852, refractive index 1.471 and optical rotation +69.80 degrees at 20 C, with the oil described as a green liquid with a mandarin aroma. If you need a GC-MS report for your own formulation, ask us in writing through the contact page before ordering. Our COA guide reads it line by line.

Whatever you came to find out, a small bottle, a clean carrier and a patch test will answer most of the rest.
