The Problem With Alcohol-Based Perfume in Indian Heat
Most synthetic perfumes sold in India use ethanol as their carrier. Ethanol evaporates fast, that's the point in a temperate climate, where the alcohol lifts the fragrance off the skin and into the air. In Indian heat, above 35°C, the evaporation happens so rapidly that the top notes disappear within 20 to 30 minutes of application. What you smell in the first burst is almost never what stays. Studies on fragrance volatility published in the International Journal of Cosmetic Science confirm that high ambient temperatures dramatically accelerate the evaporation of low-molecular-weight fragrance compounds, the very compounds that make up most synthetic top notes. By the time you've left home and reached the office, the scent has already peaked and declined.
