Perfumers Alcohol vs SD39C

    Perfumers Alcohol vs SD39C

    post #1 of 4
    Thread Starter 

    I recently purchased perfumers alcohol, but I find that it has a medicinal smell, using it, was great, would dissolve anything, Attars, oils, accords, essential oil as thick as Benzoin, but you have to wait a good 15 minutes after a spray before the real perfumic smell appears.

    i am now applying for a licence to get denatured Alcohol SD 39C, as i notice all commercial perfumes has this in the list of ingredients. 

     

    Any comments and help will be appreciated.

     

    Thank you

    Depending on the particular Perfumers Alcohol you purchased you will probably find the two are very similar in use.

     

    Normally the added ingredients in PA are more-or-less odourless solvents such as IPM, PG, DPG and the like.  These will have a minor effect on the performance of a blend, but will not significantly impact the smell of the alcohol itself.

     

    Some PA blends have aromatic ingredients added however and those can be radically different - either better or worse - depending on the ingredients used and the intended application.
