Cyclabute
Cyclabute by IFF is a quietly opulent ingredient that brings a modern, textural richness to fine fragrance compositions.
Radiating a distinctive woody–amber signature, it unveils an unexpected fruity luminosity—succulent pineapple layered with velvety mango and sun-ripened peach—before melting into a subtle yet intriguing cocoa-chocolate nuance.
The result is a multifaceted olfactory profile that feels both indulgent and sophisticated, balancing brightness with depth.
Positioned beautifully within the heart of a fragrance, Cyclabute offers exceptional tenacity compared to traditional fruity esters, while remaining more nuanced and fluid than heavier lactones.
This makes it an invaluable tool for perfumers seeking to extend and refine the fruity core of a composition without overwhelming its structure.
Its character is smoother and less herbal-anise in tone than related materials such as Cyclacet or Cyclaprop, allowing for a more seamless integration into both contemporary and classic accords.
Technically refined, Cyclabute is a colourless liquid with a flashpoint of 94°C, demonstrating both stability and versatility in formulation.
On a blotter, its presence lingers elegantly for two days or more, gradually revealing its layered complexity over time.
For perfumers and fragrance houses aiming to craft creations that feel both luxurious and distinctive, Cyclabute offers a rare balance: radiant fruit, warm gourmand undertones, and a polished woody-amber foundation—an ingredient that elevates the heart of a fragrance into something truly memorable.
