A perfume is set to have a longer shelf life in a room kept at 60 degrees. Like temperature, there are many factors that control and identify your sense of smell. But understanding fragrance requires more than just trusting your nose. At Mercado, we build a scent’s personality by finding the best chemical relationships between aroma compounds, fixatives, solvents, and essential oils. Aroma is an intimate, sensory experience, but it is also scientific and calculative – a relationship we mix well.
