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.
本发明涉及一种至少含有一种
离子液体作为固定剂的香味组合物及其制备和使用方法。本发明的香味组合物具有优势,因为
离子液体是一种没有蒸汽压的极性溶剂,可以有针对性地延缓基础香味成分的蒸发。
离子液体有多种选择,可以精确调节香味成分的蒸发速度。由于
离子液体的极性可以通过阳离子和/或阴离子的结构在很大范围内变化,因此用作固定剂的
离子液体可以精确地与香味成分的
化学物理和/或嗅觉要求相匹配。
