NOW Foods Citronella Oil (100% Pure Java Type, 1 fl oz)

NOW® Citronella Oil is a 100% pure, steam-distilled essential oil extracted directly from fresh and dried Java-type citronella grass (Cymbopogon winterianus). Celebrated for its bright, pungent, and clarifying citrus-musk aroma, pure citronella has served for generations as nature's foremost botanical tool for refreshing domestic spaces, clarifying enclosed air, and creating an outdoor sensory barrier against biting insects.

Unlike commercial patio torches or mass-market insect sprays that rely on synthetic scents and kerosene solvents, NOW Citronella Oil provides an unadulterated botanical extract. Sourced from the prized Indonesian Cymbopogon winterianus cultivar, it yields naturally higher concentrations of the volatile monoterpenes geraniol and citronellal than older Ceylon varieties, ensuring maximum aromatic projection and performance whether used in a patio diffuser or formulated into custom outdoor skin spritzers.

• Botanical Authenticity: 100% pure Cymbopogon winterianus with zero synthetic diluents, mineral oils, or artificial fragrances.
• Aroma Profile: Pungent, musky, citrus-rich, clarifying, and invigorating.
• Extraction Integrity: Low-temperature steam distilled from whole grass blades to preserve heat-sensitive monoterpenoids.
• Safety Verified: Purity tested via Gas Chromatography-Mass Spectrometry (GC-MS) for guaranteed authenticity.

Mechanism of Action: The Science Behind Olfactory Masking

A common misconception is that citronella oil acts as a lethal insecticide. In biological reality, citronella functions as a non-toxic biopesticide repellent. The United States Environmental Protection Agency (EPA) first registered oil of citronella as a botanical insect repellent in 1948 (EPA Reregistration Eligibility Decision, EPA-738-F-97-002; National Pesticide Information Center). The EPA notes that citronella poses negligible risk to humans and the environment because its repellent mechanism is purely physiological and non-toxic.

Female mosquitoes (including species in the Aedes, Anopheles, and Culex genera) hunt hosts by locking onto plumes of human respiratory carbon dioxide (CO2), convective body heat, and skin-surface kairomones such as L-(+)-lactic acid and 1-octen-3-ol. Research published in sensory entomology and biomedical reviews (Journal of Insect Science; Malaria Journal) indicates that the primary volatile monoterpenes in citronella—namely citronellal, geraniol, and citronellol—rapidly vaporize into the ambient air, saturating and inhibiting the mosquito's olfactory receptor neurons (ORNs) and gustatory receptors (GRs).

By creating an aromatic vapor barrier that blocks receptor binding sites, citronella effectively "blinds" the insect's navigation radar. Unable to locate the warm, lactic-acid-rich vapor plume emitted by human skin, the insect is repelled away from the protected perimeter.

Beyond pest deterrence, peer-reviewed botanical research (Journal of Essential Oil Research, PMC6484041) demonstrates that the aldehyde and alcohol fractions of Cymbopogon winterianus exhibit broad-spectrum antimicrobial and antibiofilm properties. The lipophilic molecules penetrate and destabilize the cellular membranes of unwanted airborne microorganisms, explaining the oil's potent deodorizing and air-purifying qualities when diffused indoors.

Complete Ingredients & Physical Specifications

NOW Essential Oils are packaged with complete analytical transparency. This product contains a single pure ingredient:

NOW® Analytical Laboratory Testing & Contaminant Verification

The retail essential oil market suffers from rampant adulteration. Cheap products are frequently diluted with odorless synthetic glycols, stretched with industrial solvents, or adulterated with less effective grass species. NOW Foods combats this through comprehensive testing in their state-of-the-art, ISO/IEC 17025 accredited in-house laboratories, processing over 16,000 analytical tests monthly to meet strict cGMP specifications.

• GC-MS & GC-FID Fingerprinting: Gas Chromatography-Mass Spectrometry and Flame Ionization Detection verify the unique chromatographic fingerprint of Cymbopogon winterianus. This confirms that natural ratios of citronellal, geraniol, and citronellol are present without trace synthetic aromachemicals.
• Physical Density & Refraction Screening: Refractive Index (1.466–1.475) and Specific Gravity (0.878–0.895) are validated with digital refractometers and pycnometers to confirm the liquid density matches pure, undiluted botanical grass oil.
• Heavy Metal Safety via ICP-MS: Raw botanicals undergo Inductively Coupled Plasma Mass Spectrometry to screen for toxic heavy metals (lead, arsenic, cadmium, mercury) down to trace parts-per-billion (ppb) thresholds.
• Multi-Residue Pesticide Analysis (LC-MS/MS & GC-MS/MS): Advanced liquid and gas chromatography mass spectrometry screens for hundreds of agricultural pesticides, fungicides, and synthetic crop treatments to prevent chemical carryover.
• Optical Rotation Testing: Polarimetric testing assesses how polarized light rotates through the oil, verifying natural chirality and weeding out racemic synthetic copies.

Every lot of NOW Citronella Oil carries a lot-specific Certificate of Analysis (COA) confirming that the product in your hands meets zero-tolerance standards for adulterants, microbes, and chemical diluents.

Practical Usage Guide, Carrier Dilution & Safety Precautions

Pure botanical essential oils are highly concentrated chemical matrices and must be handled with appropriate care. Follow these precise instructions for safe domestic and outdoor application:

1. Ultrasonic Diffusion & Patio Freshening

Add 3 to 5 drops of NOW Citronella Oil to an ultrasonic water diffuser. Place the diffuser on a covered porch, patio table, or near entryway doors to clarify the surrounding air and deter winged insects. For an enhanced outdoor synergy blend, combine:

✓ 2 drops NOW Citronella Oil
✓ 2 drops NOW Cedarwood Oil
✓ 1 drop NOW Lemongrass or Lavender Oil

2. Topical Application & DIY Outdoor Body Spritz (Mandatory Dilution)

Never apply pure citronella oil directly ("neat") to bare skin. Its active monoterpenes can cause acute contact dermatitis and cutaneous irritation.

Standard 2% Adult Dilution Ratio: Blend 10 to 12 drops of NOW Citronella Oil into 1 fluid ounce (30 ml) of carrier oil (such as NOW Jojoba, Grapeseed, or Fractionated Coconut Oil). For a non-greasy outdoor spray, blend 20 drops of citronella with 1 ounce of witch hazel and 1 ounce of distilled water in a fine-mist spray bottle; shake well before each spritz.

Critical Safety Constraints

• Not for Internal Use: Never ingest citronella oil or add it to food or beverages. Ingestion can cause mucosal irritation and systemic toxicity.
• Pet Safety Warning: Keep diffusers and topical blends away from cats and small dogs. Felines lack the hepatic glucuronyl transferase enzyme required to metabolize plant monoterpenes.
• Patch Test Recommended: Before widespread topical use, apply 1 drop of your diluted carrier blend to your inner forearm and monitor for 24 hours for signs of erythema or irritation.
• Pregnancy & Medical Conditions: Consult a licensed healthcare practitioner prior to use if pregnant, nursing, or managing chronic respiratory conditions such as asthma.

Frequently Asked Questions (FAQ)

What is the difference between Java citronella and Ceylon citronella?

Java citronella (Cymbopogon winterianus) is widely recognized as superior to Ceylon citronella (Cymbopogon nardus) for insect deterrence and aromatherapy. Java type produces roughly double the active volatile monoterpenes—specifically citronellal (approx. 27–40%) and geraniol (approx. 20–35%)—yielding a fresher, brighter citrus scent and noticeably stronger olfactory masking power.
