Aldehyde

An aroma chemical that contains a functional group consisting of a carbon, a hydrogen, and an oxygen atom. Aldehydes can be derived from natural or synthetic materials. There are different type of scents associated with this chemical function but the most commonly referred to when profiling a scent as “aldehydic” is a sharp, metallic, crisp, slightly fatty impression often associated with the smell of clean textile or hot iron. One of the first “aldehydic” fragrance is the famous N°5 created by Perfumer Ernest Beaux in 1920 and launched by Gabrielle Chanel in 1921.
