The Full Story
Lemon zest in perfumery is the cold-pressed peel oil of Citrus limon (CAS 8008-56-8) — the same expressed material as the culinary 'zest' produced by rasping the outer yellow layer of the rind. The oil is captured by mechanical pressure on the rind's oil glands, with no heat; the volatile chemistry survives the process intact.
Chemistry
Lemon peel oil is limonene-dominant (~65–75%, CAS 5989-27-5) [A], with γ-terpinene (~6–11%), β-pinene (~6–12%), citral (geranial + neral, ~2–5%), neral and geranial each providing the lemon-aldehydic angle, and small fractions of citronellal, linalool, geraniol and α-pinene. The phototoxic furocoumarin bergapten is present at modest levels — IFRA limits apply to expressed lemon oil in leave-on products.
The oils in lemon zest are so volatile that simply twisting a strip of peel over a candle flame produces a brief, fragrant flare — a trick bartenders use to garnish cocktails.
Restricted. Expressed lemon oil is phototoxic due to furocoumarin content (bergapten, oxypeucedanin); IFRA limits use in leave-on products unless furocoumarin-free (FCF) grade is used.
