The invention relates to a fragrance composition which has, as fixative, at least one ionic liquid, and to the preparation and use thereof. The fragrance compositions according to the invention are advantageous since the ionic liquid, being a polar solvent which has as it were no vapor pressure, can delay the evaporation of the base scent components in a targeted manner. The large choice of ionic liquids allows the rate of evaporation of the scent components to be adjusted precisely. Since the polarity of the ionic liquids can be varied by means of the structure of the cations and/or anions within wide ranges, the ionic liquids used as fixative can be matched precisely to the chemicophysical and/or olfactory requirements of the scent component.
