greenfatty

An intensely powerful unsaturated aldehyde with a fatty, oily-green character reminiscent of fresh fish skin, cucumber peel, and cold sea air. Extremely diffusive even at trace dosage — pushes a wet, briny greenness that can smell rancid or nauseating undiluted but reads clean-marine and violet-leaf-like in high dilution.AI · claude-opus-4-7

Appearance

Colorless oily liquid.

Solubility

Insoluble in water, soluble in alcohol and oils.

Odor

Extremely powerful, fatty-green, somewhat vegetable odor of moderate tenacity.

Flavor

The taste is pleasant only in concentrations below 0.1 ppm.

Uses in perfumery

Except for very rare applications in artificial essential oils, this aldehyde is probably not used in perfume compositions.

Uses in flavor

It finds some use in flavor compositions, e.g. in the reconditioning of flavor in fried food, 'French fried' potatoes, etc. The effect in extreme dilution simulates the flavor of Cream to a certain extent.
