Citrus junos extract
CAS 233683-84-6
What Is Citrus junos extract?
Citrus junos extract comes from the aromatic peel of yuzu, a Japanese citrus fruit. You’ll encounter its bright, tart aroma in premium citrus perfumes, gourmand candles, and Asian-inspired skincare. This extract captures the unique character of yuzu – more complex than lemon, less sweet than orange. Yuzu matters because it bridges Eastern and Western fragrance traditions. Its distinctive scent profile adds sophistication to citrus accords while maintaining natural freshness. Japanese artisans have prized yuzu for centuries in both perfumery and cuisine.
Safety Profile
GENERALLY SAFEWhat Does Citrus junos extract Smell Like?
Citrus junos extract bursts with an electrifying citrus opening – imagine a grapefruit colliding with a mandarin, sprinkled with green herbal nuances. The top notes carry a distinctive tartness reminiscent of kaffir lime, but with deeper floral undertones. As it evolves, the heart reveals subtle peppery facets and a delicate honeysuckle-like sweetness. The dry-down presents woody-herbal traces that distinguish it from common citrus oils, leaving a clean yet complex trail. Unlike lemon’s straightforward brightness, yuzu maintains intriguing dimensionality throughout its evaporation curve.

Chemistry, Properties & Perfumer Guide
The Chemistry
Citrus junos extract contains a complex mixture of volatile compounds including limonene, γ-terpinene, and nootkatone. Unlike common citrus oils, it contains higher proportions of oxygenated terpenes contributing to its distinctive character. The extract is typically obtained through cold pressing of the fruit peel, preserving delicate top notes. Recent advances in CO2 extraction yield cleaner profiles with enhanced longevity. Key differentiating components include trace sulfur compounds and unique sesquiterpenes not found in other citrus species.
