ABSTRACT: At least in theory it should be easy to keep a perfume; just keep it away from light, holding it inside his own box, and stay away from heat sources.
Unfortunately it's not enough.
The biggest enemy of a perfume is the ' evaporation , a phenomenon that affects indiscriminately any old perfume, even in the presence of its cap.
Only at the end of the Fifties appeared the first sprayers, but their presence on the market for many years was very small. One of the advantages of the system was the sealing the bottle, preventing thus the evaporation (unless sprayer breaks, very frequent in early versions, when they used some kind of propellant gas.)
