Citronella Essential Oil Supplier Malaysia

Citronella Essential Oil is a therapeutic-grade oil steam-distilled from the aerial parts of Cymbopogon nardus or Cymbopogon winterianus (citronella grass), presenting as a light yellow liquid. Best known globally as the premier natural insect repellent, Citronella Oil contains geraniol and citronellal as its primary active compounds — which are scientifically proven to repel mosquitoes, flies, and other insects by masking the carbon dioxide and lactic acid signals that attract biting insects to human hosts.

Applications:

Natural Insect Repellents (mosquito repellent sprays, lotions, candles, diffuser blends)
Personal Care (insect-repellent body sprays, outdoor protection products)
Aromatherapy (uplifting, deodorising, and insect-deterring diffuser blends)
Home & Garden (insect repellent candles, room sprays, outdoor area diffusers)

Key Features & Benefits:

Light yellow – clean therapeutic-grade citronella oil
No animal substance – suitable for vegan and Halal-compliant formulations
Proven natural mosquito and insect repellent – geraniol and citronellal active
Fresh, lemony-green aroma with deodorising properties
High demand seasonal and year-round in tropical Malaysian climate

Java or Ceylon type

Two grasses give two different oils. Java-type citronella (Cymbopogon winterianus) is rich in citronellal and geraniol, and is the type preferred for perfumery and as a source of aroma chemicals. Ceylon-type citronella (Cymbopogon nardus) has less citronellal and a harsher, more camphoraceous character. Because this listing covers either species, confirm which one a given lot is: the two are priced and perform differently.

Repellent claims are regulated

In many markets a product that claims to repel insects is regulated as a pesticide or biocide rather than as a cosmetic, and needs its own registration and approved label wording. Check the classification in each market before making repellency claims on a finished product; the oil used purely as a fragrance falls under different rules.

Formulation notes

Citronella oil contains geraniol, citronellol and limonene, which are declarable fragrance allergens in the EU and markets that follow its rules. It is volatile, so repellent performance in a spray or lotion fades as it evaporates. Store it sealed and away from light. Its close relative Lemongrass Oil shares the same genus but a very different, citral-led profile.

What the research says

A 2011 meta-analysis of 11 controlled laboratory studies found citronella oil protected against Aedes mosquitoes for 253 minutes less than DEET (95% CI 169–336). [1]
Adding vanillin may lengthen protection. In room tests, citronella products gave complete repellency for at least 3 hours. [1]
In a test of 38 oils on volunteers’ arms, undiluted citronella gave 2 hours of complete repellency. No oil diluted to 10% or 50% lasted 2 hours. [2]
A 2021 review of 16 studies found DEET 20% lotion protected longer than citronella 10% lotion. No adverse effects were reported. [3]

These summaries describe published research on the ingredient. They are not claims for any finished product; claims on finished products must meet the rules of the market where they are sold.
