Preserving Absolutes in Alcohol?

[Guest guest]

Hello All,

I could swear I recalled a few posts about adding alcohol to absolutes such as

rose or jasmine to help extend their shelf lives, but I cannot seem to find them

searching through the archives. Am I recalling this correctly?

I understand that it creates a dilution, which has its own advantages, and that

it limits you to alcohol-based perfumes. I am interested in how exactly it

helps preserve an absolute though, and what amount of alcohol to absolute or

what % dilutions are best for preservation. Also, are there certain absolutes

that need this more than others, e.g. have routinely shorter shelf lives?

Thanks for sharing your immense knowledge and experience!
