A classic muguet (lily-of-the-valley) aromachemical — soft, sweet, watery floral with a fresh green-linden facet. Rounded and creamy rather than sharp, it lends a dewy floral transparency but can read as slightly waxy and old-fashioned on its own.AI · claude-opus-4-7

Colorless oily or viscous liquid.
Very slightly soluble in water, soluble in alcohol and oils. Poorly soluble in mineral oil and glycerin or propylene glycol.
Sweet-floral, at first delicate and refreshingly mild, but often increasing in odor strength after short olfactory study. The floral notes are mild, light and resemble Lily of the Valley.
Hydroxycitronellal has a sweet-floral taste, but shows a bitter aftertaste at concentrations higher than 20 ppm, sometimes even much lower than that.
This aldehyde is one of the most frequently used floralizing perfume materials. Originally introduced as a 'Muguet' material, it finds its way into almost every type of floral fragrance, and a great many nonfloral ones. Its concentration in perfumes may vary from about 1% (which rarely gives effect unless supported by parallel materials) up to 30 or 40%, in straight floral types.
High-grade Hydroxycitronellal is used sparingly in flavor compositions as a floralizer in many types of flavor: Berry complexes, Citrus, Violet, Cherry, etc. and in general, a discrete touch of floral note in a flavor tends to give impression of 'richness' or 'body' which are highly desirable virtues.
Produced from (many methods) e. g. from Myrcene, via Myrcene dihydrochloride to Dichloro dimethyloctene. This is converted to Chloro dihydrogeranyl acetate (and -neryl acetate) with Sodium Acetate in Benzene in presence of Triethylamine. The acetates are saponified with Calcium hydroxide to yield Hydroxycitronellol, from which the aldehyde is prepared by oxidation. Older methods start from Citronellal via the Bisulfite which is hydrated to yield Hydroxycitronellal.
