Perfume and Flavor Chemicals, page 1241.
Colorless oily liquid. Solidifies in the cold.
Insoluble in water, poorly soluble in propylene glycol and glycerin, soluble in alcohol and oils.
Warm and sweet, soft, floral-anisic, mildly spicy and tenacious odor. Sweeter, more floral, more anisic, less woody-spicy than Safrole.
Sweet, warm, mostly floral taste in concentrations near 30 ppm. Tends to appear perfumey at higher concentrations.
The title material is very well known by name, but hardly ever used as such in perfumery. It serves as an intermediate in the manufacture of Heliotropine, although certain methods avoid this step altogether.
Iso-Safrole is not permitted in flavors in the U.S.A., and also banned from food flavors in most other countries.
Produced from Safrole by treatment with potassium or sodium hydroxide in dry state or alcoholic solution, under pressure or at atmospheric pressure.
