What Is Benzaldehyde glyceryl acetal?
Benzaldehyde glyceryl acetal is a synthetic fragrance ingredient that creates sweet, almond-like aromas. You’ll find it in gourmand perfumes, cherry-flavored products, and some almond-scented cosmetics. This molecule matters because it provides long-lasting cherry-almond notes without the volatility of natural benzaldehyde, making scents more stable in products like lotions and soaps.
Safety Profile
USE WITH AWARENESSWhat Does Benzaldehyde glyceryl acetal Smell Like?
Opens with intense marzipan sweetness reminiscent of crushed cherry pits, evolving into a dense almond paste heart. The dry-down reveals subtle woody undertones that distinguish it from simpler benzaldehyde derivatives. Unlike fleeting natural almond notes, this acetal lingers with a polished, almost liqueur-like richness that bridges gourmand and oriental accords.

Chemistry, Properties & Perfumer Guide
The Chemistry
Benzaldehyde glyceryl acetal belongs to the acetal class, formed by reacting benzaldehyde with glycerol. This molecular structure protects the aldehyde group, granting superior stability against oxidation compared to free benzaldehyde. The synthesis typically involves acid-catalyzed condensation, yielding a mixture of five- and six-membered cyclic acetals that influence its odor profile.
