A soft, sweet almond-cherry aroma reminiscent of benzaldehyde but rounder, less sharp and more tenacious. The glyceryl acetal masks the raw bitter-almond bite, giving a smoother marzipan-like sweetness with faint balsamic and heliotrope facets.AI · claude-opus-4-7

Colorless viscous liquid.
Soluble in alcohol and oils.
The acetal itself has a very faint odor, barely reminiscent of Bitter Almond.
Used in fruit flavors, imitation Almond, Cherry, Nut, etc. in concentrations equal to 100 ppm in the finished consumer product.
Used in flavor compositions where lower volatility and improved stability towards air (oxygen) is desirable, and Benzaldehyde as such seems too volatile and unstable.
Chewing gum may contain up to 800 ppm of the acetal. Chewing gum is the most common outlet for this acetal.
Produced from Benzaldehyde and Glycerin by condensation, using Phosphoric acid as a catalyst, and making use of azeotropic distillation to remove reaction water. Also by heating Glycerol and Benzaldehyde in CO2 atmosphere to 150° C.
