Linalool Uses
Linalool is a monoterpene alcohol compound with the chemical formula C₁₀H₁₈O. It is widely found in natural plants and can be produced by chemical synthesis. It has a unique fresh floral and woody fragrance and is one of the important raw materials in the flavor and fragrance industry.
I. Flavor and fragrance industry
Linalool is the core ingredient in perfumery. It is widely used in the formulation of various fragrances due to its variable aroma characteristics (the left-handed body is more floral and the right-handed body is more woody).
Perfume: As a middle or base note, it gives perfume an elegant floral scent (such as lavender, lily of the valley) or woody feel, which is common in high-end perfume formulas.
Cosmetics and skin care products: used in lotions, shampoos, shower gels, etc. to provide soothing fragrance and may also assist in preservation (inhibiting bacterial growth).
Aromatherapy products: used in essential oils, scented candles, and diffuser stones to exert a calming and relaxing effect (such as the main ingredient in lavender essential oil).
II. Daily Chemical Products
Detergents and Softeners: Added to laundry detergents and fabric softeners, they give clothes a fresh floral and fruity scent and cover up chemical residual odors.
Antibacterial Products: Using its natural antibacterial properties, it is used in hand sanitizers and disinfectant sprays, which have both odor improvement and functional enhancement.
III. Food Industry
Food additives (usually synthetic linalool, which meets food safety standards).
Beverages: Give citrus, lychee and other flavors, commonly found in soft drinks and teas.
Candy and Baking: Used in chewing gum, ice cream, and cakes to enhance the fruity flavor.
Tobacco: As a tobacco flavor, it reduces the irritation of tobacco leaves and improves softness.
IV. Industry and Chemicals
Solvents and Intermediates: Used as solvents in electronic cleaning agents; used as precursors in chemical synthesis to prepare vitamin E, geraniol, etc.
Insecticide synergists: Some studies have shown that they can enhance the effects of botanical insecticides, but they are rarely used.
