What aromatic compounds are in the rose hydrosol (GC-MS profile)?

Question

Accepted Answer

The GC-MS fingerprint is dominated by phenylethyl alcohol (2-phenylethanol), supported by citronellol and geraniol — the classic markers of genuine rose water. CompoundRole2-Phenylethanol (苯乙醇)Signature sweet-rosy note, dominant markerCitronellol (香茅醇)Fresh rosy-citrus liftGeraniol (香叶醇)Rounded floral sweetnessTrace alcohols & estersComplexity, honeyed undertonesBecause these molecules are water-soluble, they pass into the hydrosol phase in measurable amounts, unlike heavier oil-soluble components that stay in the essential oil. The profile is a reliable authenticity tool — it distinguishes genuine distillate from synthetic rose-scented water.Ask for the GC-MS chromatogram of your batch as part of the COA package.
