Natural citral is widely used in the fragrance and flavor industry due to its strong lemon-like aroma. It is a key ingredient in perfumes, soaps, detergents, and cosmetics, where it provides a fresh, citrus scent. In the food industry, it is used as a flavoring agent in citrus-flavored products such as beverages, candies, and baked goods. Citral also serves as a starting material for the synthesis of other aroma chemicals like ionones and methyl ionones, which are used in perfumery. Additionally, it exhibits antimicrobial properties, making it useful in natural preservatives and essential oil-based disinfectants.

Furthermore, natural citral has insect-repelling properties, often incorporated into natural insect repellent products, especially those derived from essential oils like lemongrass, where citral is a primary component.

In aromatherapy, traditional medicine, and herbal products, citral plays a role in promoting relaxation, reducing stress and anxiety, and supporting mental well-being. Its natural origin makes it preferred in organic, natural, and eco-friendly product formulations.
