* Solvent: The main component, usually ethanol (alcohol), acts as the solvent. It's the substance that dissolves the other ingredients.
* Solutes: These are the fragrant oils and aroma compounds that give perfume its scent. They are dissolved in the alcohol.
Since the fragrant oils are dispersed evenly throughout the alcohol and don't separate out, perfume fits the definition of a solution: a homogeneous mixture of two or more substances.
