In short
Java citronella oil is distilled from Cymbopogon winterianus and is rich in citronellal, geraniol and citronellol. It is best known from functional products and as a natural source of those constituents.
What Citronella Oil (Java) smells like
Citronella oil is fresh, lemony and grassy, with a rosy side — the smell most people associate with citronella candles. Two types differ in composition and odour: Java-type is richer in citronellal and is preferred in perfumery for its fresh, sweet, lemony aroma; Ceylon-type is richer in geraniol and has been judged crude and heavy by comparison, unbalanced by its herbaceous elements. The type names describe the oil's character rather than where it was grown.

What makes Citronella Oil (Java) distinctive
Lemon pulled towards rose: citronellal's lemony green plus geraniol's rosiness, in proportions that differ between the Java and Ceylon types.
How Citronella Oil (Java) is used
Used in functional and household fragrance and insect-repellent products, and as a source of citronellal and geraniol.
Typical role: modifier (used in small amounts to change the character of a blend).
How Citronella Oil (Java) differs from similar materials
- Citronellal
- Citronellal is the oil's lemony-green core; the oil adds geraniol's rosiness and grassy, herbaceous notes.
- Lemongrass Oil
- Lemongrass is citral lemon with a dry, grassy body; citronella is rosier and more citronellal-led.
- Lemon Eucalyptus Oil
- Lemon eucalyptus is almost all citronellal, with a balsamic-floral drydown; citronella is grassier and rosier.
- Melissa Oil
- Citronella oil is used to imitate melissa; melissa is softer, more herbal and more delicate. (compared directly by a cited source)
