Апельсин

Sweet orange (Citrus sinensis) is itself a hybrid — a cross between pomelo (C. maxima) and mandarin (C. reticulata) — though this hybridization occurred so long ago in Southeast Asia that the sweet orange has been treated as its own species for centuries. It is the world's most cultivated citrus, with Brazil, the United States (Florida, California), and Spain as major producers.

The essential oil is obtained by cold pressing the peel and contains 90-97% D-limonene — a higher concentration than in any other frequent citrus oil. However, as with lemon, limonene provides generic citrus character; the specific sweet-orange identity comes from minor components: octanal, decanal, linalool, and various esters. The oil is relatively inexpensive, making orange one of perfumery's most accessible raw materials.

In perfumery, orange functions as a top note — bright, sweet, and immediately recognizable, with less acidity than lemon and less bitterness than grapefruit. It is the warmest of the common citrus notes, reading as solar and approachable. The note fades relatively quickly due to limonene's volatility, but it provides a welcoming, uncomplicated opening.

Orange oil is structural in eaux de cologne, citrus-floral compositions, gourmand accords, and chypres. It pairs naturally with spices (cinnamon, clove), flowers (neroli, orange blossom — from the same tree's flowers), and warm bases (vanilla, amber). The oil oxidizes easily and has limited shelf stability, requiring careful storage.
