Solubility

Practically insoluble in water, soluble in alcohol and oils.

Odor

Powerful and penetrating, warm-herbaceous, minty-camphoraceous odor of moderate to poor tenacity.

Flavor

Warm-herbaceous, bitter taste in concentrations lower than 10 ppm. Higher concentrations produce pungent-bitter, herbaceous taste.

Uses in perfumery
