What is Citral?

Citral is an acyclic monoterpene aldehyde, primarily a mixture of neral and geranial isomers, extracted from essential oils of plants like lemon, lemongrass, and orange. It belongs to the class of terpenoids and imparts a fresh, citrus-like aroma. In cosmetics, it appears in perfumes, soaps, shampoos, and oral care products within the fragrance category. Functionally, it acts as a volatile scent carrier, blending with other notes to create balanced olfactory profiles, while also serving to cover off-notes from base ingredients. Its lipophilic nature allows even dispersion in oil-based formulas, enhancing product stability and appeal without altering texture. Derived botanically, it's prized for natural sourcing in clean beauty formulations, subject to purity standards to minimize impurities.
