CHANEL's official page describes N°5 Eau de Parfum based on a bouquet of rose and jasmine enhanced by aldehydes. The reference to the latter is part of the composition's language, not an evaluation conducted here. Identifying the exact version facilitates an orderly comparison within N°5. The sheet does not extend these notes to other concentrations nor promise an identical experience for each person.
