Rosa x damascena absolute is produced by solvent extraction of the concrete, yielding an orange-red liquid chemically distinct from the steam-distilled otto: absolute is dominated by phenylethyl alcohol (~78%), whereas otto is characterised by citronellol and geraniol (>55% combined), reflecting the absolute's capacity to capture wax-soluble and heat-labile aromatic compounds lost during distillation.^[1] The solvent process also concentrates higher levels of tocopherols and carotenoids relative to essential oil and hydrosol, contributing to the richer, deeper aroma profile prized in perfumery.^[1]
