Definicija

Tart, sparkling, faintly sulfurous. Grapefruit smells like sunrise on a terrace — a bright citrus burst with a bitter edge, a juicy sweetness, and an almost metallic tang that no other citrus possesses.

Miris

More bitter than orange, less acid than lemon, with a sulfurous-metallic undertone that neither possess. Grapefruit opens with explosive citrus brightness — d-limonene's clean, universally recognizable sparkle — then immediately reveals the nootkatone signature: a bitter, slightly woody, almost grapefruit-rind quality that is drier and more persistent than any other citrus. There is a faint thiol note (mercaptan compounds at trace levels) that adds a sulfurous, almost tropical edge. On blotter, the limonene-dominant top vanishes in under an hour, but nootkatone, being a sesquiterpene, persists noticeably longer than typical citrus notes.

Detaljno

Grapefruit (Citrus × paradisi) is a hybrid of pomelo (Citrus maxima) and sweet orange (C. sinensis), thought to have originated in Barbados in the seventeenth or eighteenth century. The cold-pressed peel oil (CAS 8016-20-4) is the standard perfumery natural; it is limonene-dominant like all citrus, but two minor compounds make grapefruit immediately recognisable.

The two signature compounds

Nootkatone (CAS 4674-50-4, a sesquiterpene ketone, C₁₅H₂₂O) is the woody-bitter heart of grapefruit [A] — it carries the characteristic grapefruit angle from limonene's plain citrus. Even more important at trace level is 1-p-menthene-8-thiol (CAS 71159-90-5), the powerful sulphur thiol that supplies the metallic-fresh juicy quality, identifiable below ~10 ppb in finished fragrance [B]. Together these two compounds — both at trace levels — turn an otherwise ordinary citrus oil into something only grapefruit smells like.

Dobijanje i hemija

Način dobijanja

Cold pressing of Citrus x paradisi peel. The oil is 90-95% d-limonene with 0.01-0.8% nootkatone — the sesquiterpene ketone responsible for the characteristic grapefruit identity. Cold-pressed oil contains phototoxic furocoumarins (IFRA-restricted in leave-on products). Distilled grapefruit oil is furocoumarin-free but lacks some peel-fresh character. Nootkatone can be used as an isolate to deliver grapefruit character without phototoxicity restrictions.

U parfemima

Grapefruit functions as a top note with slightly longer tenacity than most citrus materials, thanks to nootkatone's sesquiterpene weight. It provides a bright, bitter-fresh opening for cologne, hesperidic, fresh-spicy, and green-citrus compositions. The bitterness distinguishes it from sweeter citrus notes (orange, mandarin) and makes it a natural partner for green tea, vetiver, pepper, and woody-mineral bases. Grapefruit is prominent in the modern cologne genre, where its clean tartness creates a unisex freshness.
