Litsea cubeba essential oil

Litsea cubeba is not a citrus: its oil comes from the berries of Litsea cubeba, a Lauraceae1. It contains 78.7 to 87.4% of neral and geranial, that is, citral4. Citral is named in Annex III of Regulation (EU) 2023/1545: declare it above 0.001% leave-on and 0.01% rinse-off2.

What the research says

Each result shows the protocol and the level of evidence. The higher the level, the better the result carries over to a finished formula.

Clinical trialReview or consensusLaboratory

Oil compositionChemistry

Neral and geranial at nearly 80 to 87%

Laboratory
Fruits harvested in 8 regions of ChinaHydrodistillation, GC-MS59 compounds identified

Monoterpenes represent 94.4 to 98.4% of the oil, mostly neral and geranial (78.7 to 87.4%). D-limonene is minor (0.7 to 5.3%). Composition varies markedly by region4.

An oil studied mostly for food

Review
2024 review

The review describes an oil with a broad antimicrobial spectrum and strong antioxidant activity in the laboratory, whose composition depends on several factors. It concerns the food industry, not cosmetics5.

Citral: allergy and thresholdsToxicology

A human induction threshold

Review
Review of the available literatureWeight-of-evidence approach

The no observed effect level for induction of skin sensitization to citral is 1,400 µg/cm². The authors work for the research institute of the fragrance industry6.

Citral: allergen and irritant

Clinical study
586 consecutively tested peopleClinic populationCitral at 2% in petrolatum

28 people had a positive test to citral and 82 an irritant reaction without a positive test. The authors conclude that citral can be allergenic and irritant7.

Citral, geranial and neral: 1.9 to 3.4% positive tests

Clinical study
1,476 consecutively tested peopleCitral, geranial and neral at 3.5% in petrolatum

Tests are positive to citral in 2.9% of people, to geranial in 3.4% and to neral in 1.9%. Among reactions to citral or its components, 61% come with a reaction to oxidized geraniol8.

Use on skinLaboratory

Citral and melanin production, in a formulation

Laboratory
Blend of Litsea cubeba, Pinus mugo and Cymbopogon winterianusOil-in-water emulsion and oily solutionNon-occlusive and semi-occlusive application

Citral showed inhibitory activity on tyrosinase, an enzyme of melanin production. The blend aims to lower the citral content to limit skin reactions. The oil-in-water emulsion releases the active compounds quickly, and semi-occlusive application limits their evaporation9.

6% spray: skin tolerance and protection against mosquitoes

Clinical study
Spray with 6% oil48 healthy volunteers, patch testWHO cage protocol, 3 mosquito species

No visible skin reaction up to 96 h. The median complete protection time is 225 minutes against Culex quinquefasciatus and 120 minutes against Aedes aegypti and Anopheles dirus. This is a repellent use, outside cosmetics10.

Frequently asked questions about litsea cubeba oil

What is litsea cubeba oil?
It is the volatile oil obtained from the berries of Litsea cubeba, a Lauraceae1. Its INCI name is LITSEA CUBEBA FRUIT OIL. Despite its lemony scent, it is not a citrus: it is 78.7 to 87.4% neral and geranial, that is, citral4.
What are the benefits of litsea cubeba oil for skin?
CosIng classifies it as a fragrance and a tonic1. We retained no robust cosmetic clinical trial on skin: the available studies concern its composition, food use5 and a repellent spray10. One formulation study looks at the effect of citral on tyrosinase9.
Do I have to declare litsea cubeba in the ingredient list?
The oil is not named in Annex III, but the citral it contains is: it must be declared, as "Citral", above 0.001% in a leave-on product and 0.01% in a rinse-off product2. With 78.7 to 87.4% citral in the oil4, the threshold is reached even at very low use levels.
Is litsea cubeba allergenic?
Its main component, citral, is an allergen and an irritant: 28 of 586 people reacted positively in one study7, and 2.9% of 1,476 people in another8. The no observed effect level for induction is 1,400 µg/cm²6: the final dose of a product is calculated with your safety assessor.
Is litsea cubeba photosensitizing?
The CosIng database refers it to no restriction1, and we retained no phototoxicity study on this oil. Furocoumarins fall under Annex II, line 3583: ask for the certificate of analysis of your batch.
What is the difference between litsea cubeba, citronella and lemon?
Lemon is a citrus rich in limonene; litsea is a Lauraceae rich in citral4; citronella (Cymbopogon winterianus) is a grass rich in geraniol, citronellal and citronellol11. Each oil has its own page.
Can you manufacture a litsea cubeba product for my brand?
Yes. Our ISO 22716 certified lab can add litsea cubeba to a catalog formula that you customize or to a custom formula, taking citral declaration into account. Samples are free.
