Percocet used for pain relief is a narcotic medication and prescriptions can prevent people from getting high on Percocet without medical reason.In fact, the Percocet high feeling can get you into lots of problems.
I think the formula of the perfume itself decides how fast it will spoil. My perfumes from Britney Spears Curious and Salvatore Ferragamo went bad within a year and a half. The Britney Spears one developed some precipitation and started smelling like alcohol, while the Salvatore Ferragamo just smelled plain weird.
Perfumes basically are three-part mixtures of chemicals. The first part, the fragrance, is the one that we usually think about. These are generally esters, aldehydes, or aromatic organic compounds that occur naturally in flowers, fruits, or other things that smell nice. The second part, the. solvent, is used to dissolve all the fragrance, and evaporate slowly so that the perfume's scent is given off over a period of time, and not all at once.
