🌿 Benefits and Industrial Uses of Citronella Oil

Introduction
Citronella oil is one of the most commercially valuable essential oils in the global aromatics industry. Extracted primarily from the leaves of the Cymbopogon nardus and Cymbopogon winterianus plants, citronella oil is widely recognized for its fresh, citrusy, and slightly herbaceous aroma.
Beyond its well-known use as a mosquito repellent, citronella oil plays a significant role in industrial applications including personal care manufacturing, agarbatti production, home fragrance formulation, and surface cleaners.
In this article, we explore its key benefits, chemical composition, and major industrial applications.
______________
1️⃣ What is Citronella Oil?
Citronella oil is a steam-distilled essential oil obtained from aromatic grasses native to Southeast Asia. It is classified into two main types:
•    Ceylon Type (Cymbopogon nardus)
•    Java Type (Cymbopogon winterianus)
The Java type is generally preferred in industrial applications due to its higher concentration of citronellal and geraniol.

2️⃣ Key Chemical Components
The effectiveness of citronella oil depends largely on its chemical profile. Major constituents include:
•    Citronellal
•    Geraniol
•    Citronellol
•    Limonene
A GC/MS analysis is typically conducted to verify purity and composition, especially for export-grade material.
