Uses in Perfumery & Cosmetics
Limonene is widely used to provide a fresh, sparkling citrus top note. It works particularly well in orange, lemon, bergamot, grapefruit, cologne, fresh, herbal, fruity and woody fragrance compositions. In perfumery, it blends particularly well with Citral, Linalool, Linalyl Acetate, Geraniol, Citronellol, Nerol, Dihydromyrcenol, Bergamot, Lavender, Rosemary, Cedarwood and other citrus materials.
Cosmetic Function
Besides its fragrance function, limonene is also used as a solvent and formulation ingredient in some cosmetic and household products. Because it is lipophilic, it can help dissolve certain oil-soluble aromatic materials.
Important: Limonene is a regulated fragrance allergen in several markets, and oxidized limonene is more sensitizing than fresh limonene. Products containing it should be protected from excessive heat, light and air, and finished-product usage and allergen labeling should be assessed for the intended market.
