aldehydes smell review

Aldehydes are organic compounds that are present in many natural materials, such as rose, citronella, cinnamon bark, and orange rind, and are also a family of synthetic chemicals. They are versatile compounds that can help make resins, dyes, organic acids, and perfumes for cologne, detergents, and soaps. Aldehydes are used in perfumery to add a sweet or fresh scent to fragrances. They are a family of ingredients that can be metallic, starchy, citrusy, or waxy. The most widely used aldehydes in perfumery are C7 (heptanal, naturally occurring in clary sage and possessing a herbal green odor), C8 (octanal, orange-like), C9 (nonanal, smelling of roses), and C10 (decanal, powerfully evocative of orange rind) . Aldehydes can be reproduced synthetically in a laboratory and contain what is known as a formyl group, which is part of a molecule with a specific structure (R-CHO) in organic chemistry. Aldehydes vary in smell, and those with a lower molecular weight can have an unpleasant odor, resembling the malodors of rotting fruit, while those with a higher molecular weight often have very pleasant aromas.
