A powerful aldehydic material with a fatty, waxy character reminiscent of orange peel and neroli. Opens with a soapy-citrus brightness that softens into a floral, slightly greasy skin-like warmth. Signature Aldehyde C-11 oxy character — rounder and more floral than the straight fatty aldehydes.AI · claude-opus-4-7

Appearance

Colorless viscous liquid.

Solubility

Practically insoluble in water, soluble in alcohol and oils.

Odor

Powerful, floral-green, very diffusive, yet tenacious odor, reminiscent of Rose petals, Lily, Muguet, Peony, etc., but overall greener than the straight florals.

Uses in perfumery

Interesting in perfume compositions where it may introduce desirable waxy-floral petal-notes in above floral types, or it may be a part of a topnote composition which can be Citrusy, floral or aldehydic. It lends power and tenacity to such materials.

Production

From Decanol plus Sodium Methylate. The Acetal which is formed is subsequently reacted with Bromodimethyl acetal. The resulting Acetal is finally hydrolyzed with Oxalic acid to yield the Aldehyde.
