Rhodinol Usage And Synthesis

Uses

Rhodinol is a flavoring agent that is a colorless liquid, with an odor resembling rose. It is soluble in most fixed oils, mineral oil, and propylene glycol, insoluble in glycerin. It is usually obtained from reunion germanium oil.

Uses

Rhodinol is an expensive perfume material (about twice the cost of Geranium oil) but it is unsurpassed in floral beauty. It can not be replaced by any grade of Citronellol (synthetic or Citronella-isolate) in a composition. The flavor chemist may be even more discriminate, since “Rhodinol” is used as a Sweet undertone In 3trawberry, Kaspberry, Currant, Honey, Grape and in fruit complexes, spice blends, Ginger Ale flavor, Chocolate imitation, etc. The concentration is normally about 1 to 10 ppm in the finished product, except in chewing gum, where it may reach 30 ppm.

Safety Profile

Moderately toxic by intramuscular route. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
