What is a Citral?

Citral is a terpene compound with the chemical formula C₁₀H₁₆O, commonly found in citrus fruits like lemons, oranges, and in plants such as lemongrass. It is known for its fresh, lemon-like scent, which is why it is widely used in the production of fragrances and essential oils. Chemically, citral exists as two isomers: geranial (citral A) and neral (citral B), which have nearly identical chemical structures, but differ slightly in their aroma and properties.

Citral has a variety of uses, especially in the fragrance industry, where it is used to provide a citrus-like scent to perfumes, soaps, and cosmetics. It also has antibacterial and anti-inflammatory properties, making it a valuable ingredient in skincare products and pharmaceuticals. The presence of citral in lemongrass oil, for example, is well known for its natural antimicrobial effects, which are also beneficial in products that require a refreshing or deodorizing element.

Additionally, citral serves as an attractant for certain insects and organisms, which has led to its use in agriculture as a natural pesticide or insect repellent. Its versatility and natural properties make it a popular ingredient in many health and wellness products.
