You know the scenario; you are sharing cramped quarters (an elevator, subway car or public bus) with someone who clearly showered in Axe after spending an hour on exercise equipment. The scent is strong, and it is far too early in the day for an attack on your olfactory senses. Some days, that person is the guy who works down the hall; some days, that guy, unfortunately, is you. While a strong cologne might be considered preferable when you don't have time to shower after the gym, you need to be sure you are wearing the right fragrance at the right time. And that involves a little knowledge about the fragrance industry.
Though it is commonly assumed that colognes are the preferred men's fragrances, the title of "eau de cologne" is actually more specific than that. Fragrances are grouped according to the concentration of aromatic compounds found in each style. At the bottom of the list are compounds with the lightest concentration, such as splash and aftershave. These are followed by compounds with increasing levels of concentration, such as perfume mist, cologne, eau de toilette and finally, eau de parfum, which has the highest levels of concentration.
