Documented Uses

• Table: Reported uses (ppm): (Flavor and Extract Manufacturers' Association, 1994) [Table#6302]
• Citronellol is one of the components responsible for the insect repellent properties of citronella oil ... Citronellol finds extensive use in floral fragrances and in flavors for citrus and other fruit notes. Its stability makes it particularly useful in fragrances for soaps, detergents, and other household products. Citronellol is also important as an intermediate in the synthesis of a number of other aroma chemicals ... Citronellol is the key feedstock for the synthesis of rose oxide.
• Citronellol is one of the most widely used fragrance materials, particularly for rose notes and for floral compositions in general. As flavor material, citronellol is added for bouquetting purposes to citrus compositions. It is the starting material for numerous citronellyl esters and for hydroxydihydrocitronellol, an intermediate in the production of hydroxydihydrocitronellal.
