Citronella essential oil is a bright, lemon-scented oil steam-distilled from the leaves (grass blades) of the citronella plant, Cymbopogon nardus. It is best known for its fresh, clean, citrusy aroma and is widely used in candles, room sprays, soaps and diluted skincare blends. Azlok's citronella oil is produced in India and comes as a clear, thin, colourless liquid that blends easily into most DIY and cosmetic projects.
What is citronella essential oil?
Citronella is a tall tropical grass, and its aromatic leaves are the source of this oil. Through steam distillation, the plant releases a pale, free-flowing oil with a distinctive lemony-fresh scent that many people find uplifting and refreshing. Because the aroma is strong and pleasant, citronella is a common ingredient in perfumery, home fragrance and outdoor products.
A few useful specifications for makers: botanical name Cymbopogon nardus, CAS 8000-29-1, specific gravity around 0.917, refractive index 1.468, flash point 85°C, and a shelf life of roughly two years when stored well. It is soluble in alcohol, which makes it handy for sprays and cleaners.
Common uses of citronella oil
- Candle making: A classic scent for outdoor and patio candles. Its lemony aroma carries well in wax.
- Room and linen sprays: Mixed with alcohol and water for a fresh, clean-smelling home spray.
- Soap and cosmetics: Added at low percentages to soaps, lotions and bath products for fragrance.
- Natural cleaning blends: Combined with vinegar or castile soap for a bright-smelling surface cleaner.
- Aromatherapy diffusing: A few drops in a diffuser for an energising, citrusy atmosphere.
How to use citronella essential oil
Citronella is a concentrated oil, so a little goes a long way. Here are practical starting points:
- Diffuser: 3–5 drops in a water diffuser is usually enough to scent a room.
- Skin blends: Always dilute in a carrier oil such as coconut, almond or jojoba. A safe general dilution is 1–2% — roughly 6 to 12 drops per 30 ml of carrier oil.
- Candles: Follow your wax manufacturer's recommended fragrance load and add the oil once the wax has cooled to the correct temperature.
- Room spray: Combine with a small amount of alcohol first to help it disperse, then top up with distilled water and shake before each use.
Blending ideas
Citronella pairs nicely with a range of oils. For a calming mix, blend it with lavender. For something warmer and woody, try cedarwood or cypress. A small touch of clove adds spice and depth. These combinations work well in both diffuser blends and candles.
Safety notes
Treat citronella like any concentrated essential oil:
- Never apply neat (undiluted) to skin — always dilute in a carrier oil.
- Do a patch test on your inner arm before wider skin use, and stop if irritation appears.
- Do not ingest the oil.
- Keep away from children and pets, and out of the eyes.
- Use in a well-ventilated space and keep away from open flame — the flash point is around 85°C.
- If you are pregnant, breastfeeding or have a medical condition, consult a qualified practitioner before use.
Buying and storage tips
Azlok offers citronella essential oil starting at ₹399, with pack sizes from 100 GM up to 25 KG, so it suits both home hobbyists and small businesses buying in bulk. Look for a clear, thin liquid with a characteristically fresh, lemony scent.
To protect the oil, store it in a tightly closed bottle away from direct sunlight and heat. A cool, dark cupboard is ideal. Kept this way, the oil holds its quality for about two years. Amber or dark glass helps slow down light exposure, and always reseal the cap promptly to reduce evaporation and oxidation.
