Can anyone explain to me just how heat and/or humidity effects bottled fragrances of any or all dilutions? Do chemicals breakdown? Separate? Go rancid? What's the prevalance of preservatives or antimicrobials in fragrances?
Inquiring geek mind would like to know. :P
Heating bottles and the content deteriorate their quality as a result of decomposition of certain components. The more and longer heat, the sooner is your frag degradated and simply "other".
