In short
Pharaone is 2-cyclohexylhepta-1,6-dien-3-one, a very powerful green ketone with a pineapple note. It is supplied at 10% in dipropylene glycol.
What Pharaone smells like
The Good Scents Company lists the 10% material as green, pineapple, fruity and herbaceous, very powerful and diffusive, for freshness and lift in top and middle notes. Fraterworks describes a crisp, intensely green aroma reminiscent of pineapple rind, with galbanum-like sharpness, tomato-leaf herbal facets and a metallic-ozonic lift. A patent example describes the neat compound as green-galbanum, fruity-pineapple and metallic.

What makes Pharaone distinctive
A green note with a fruit inside it: galbanum sharpness and pineapple rind at once.
Where the descriptions disagree: The patent stresses galbanum and metallic notes more than the commercial descriptions, which lead with pineapple and freshness.
How Pharaone is used
Used at very low levels for top-note freshness in citrus, floral, fruity, green and fougère accords.
Typical role: modifier (used in small amounts to change the character of a blend); lift (adds diffusion and radiance, especially at the top).
How Pharaone differs from similar materials
- Galbanum Resinoid
- Galbanum resinoid is the natural green, balsamic and woody; Pharaone gives galbanum's sharpness with pineapple rind and a metallic edge.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
Formulation considerations
Extremely potent; sold as a 10% solution in DPG, and formulas usually give it at that strength.
