GENERALLY SAFEWhat Does Orange peel, sweet, alcoholate Smell Like?
Bursting with the vibrant, sun-kissed aroma of freshly peeled oranges, this alcoholate opens with a juicy, almost effervescent citrus punch. The initial brightness mellows into a rounded sweetness reminiscent of orange marmalade, with subtle green undertones from the peel’s white pith. Unlike cold-pressed oils, the alcohol extraction preserves delicate top notes while eliminating harsh terpenes, resulting in a smoother dry-down that lingers as a soft, candied citrus whisper.

Chemistry, Properties & Perfumer Guide
The Chemistry
Sweet orange peel alcoholate is produced through alcoholic maceration of Citrus sinensis peels, concentrating oxygenated compounds while reducing monoterpene hydrocarbons. The process preserves delicate aldehydes like octanal and decanal that contribute to the fresh-peeled character. Unlike steam-distilled oils, alcohol extraction captures non-volatile components like coumarins and flavonoids that add depth and tenacity.
