Citrus Aurantifolia (Lime) Oil

What is Citrus Aurantifolia (Lime) Oil?

Citrus Aurantifolia (Lime) Oil is a volatile essential oil derived from the rind of the lime fruit, Citrus aurantifolia, a citrus species originating from tropical regions. Typically extracted through cold-pressing the peel for expressed oil or steam distillation for distilled variants, it falls under citrus essential oils used in personal care formulations. Its composition features predominantly hydrocarbon terpenes like d-limonene, β-pinene, and γ-terpinene, alongside aldehydes such as citral and esters. In cosmetic products, it primarily acts as a perfuming agent to deliver a sharp, citrusy aroma that enhances sensory appeal; supports skin conditioning by providing emollient and tonic effects for a refreshed feel; aids cleansing through surfactant-like properties that emulsify and remove lipids; and contributes to hair conditioning by smoothing strands. Commonly incorporated into cleansers, toners, shampoos, body washes, and fragranced emulsions at low levels.
