Colorless, viscous liquid.
Insoluble in water, soluble in alcohol and perfume oils.
Powerful and moderately diffusive green-rosy, sweet Lily-Muguet-like odor.
Occasionally used in flavor compositions for floral or fruity types, and in Rose type flavors. The concentration is usually mere traces in the finished product.
Used in perfume compositions as a floralizing aldehydic topnote ingredient, primarily in Muguet-Lily fragrances, but also in Rose, Peony (where the Geranyl-isomer is claimed to be superior), and various modifications of modern-aldehydic fragrance types.
Produced from Citronellol, reacted with Sodium methylate or Sodium iso-propylate. The acetal is then prepared by reaction with Chlorodimethylacetal. The resulting acetal is finally hydrolyzed with diluted oxalic acid to yield the aldehyde.
