Fragrance Alcohol - any insights

Not an area that I have a lot of experience, but a Private Label customer is asking me to formulate a perfume.

What I had in mind is denatured alcohol with iso propyl myristate and dipropylene glycol.

All I can find locally in Malaysia is something denatured with Brucine Sulfate.
Globally,  the jury is out on  this ingredient. The scientific literature and international cosmetic ingredient review expert panels conclude that there is not sufficient data  to support the safety of Alcohol Denat.  with  Brucine Sulfate.

The the ooptionother option is  Alcohol Denat. with DEP. Not exactly the flavour of the month these days.

Our customer base is largely Millenial Mums who look at ingredient list closely these days.

Any suggestions?

Thanks

    There is a product call "Perfumer's Alcohol" that is generally used for perfumes ... you might want to do a bit of research and see if there is a source in your locale.

    First see if the fragrance dissolves fine in alcohol with no solubilizers like IPM or DPG.

    Second see if your fragrance lasts too short a time
    so your formula may benefit from a fixative
    but don't expect fixatives to do miracles
    at most fixatives may extend fragrance "life" 1.5x. Consider yourself very very lucky with 2x.
    Fixatives just won't make cheap copycat fragrances last anything like top perfumes with expensive base notes.
    Fixatives deaden fragrances, so you'll need more overall fragrance levels for the same result.

    Third. Fixative mixtures work better than single ones.

    (stay away from potentially toxic fixatives like phtalates or coumarin.

    Fourth
    Surf a fragrance specific website like basenotes.com

    Fifth

    In Australia, The Ethanol used for perfumery is PGF4 grade and is denatured with 0.25% Tertiary Butyl Alcohol.

    Hope this helps. :)

    I posted earlier trying to find out the difference between the ethanol in perfumers alcohol and the ethanol in methylated spirits. Given that in Australia  coles home brand  meths is only ethanol 95% and water 5% with no toxic denaturant added. I really want to know the answer to this for use in a room spray and to solubilize EO in a roll on perfumed oil but getting my hand on the perfumers alcohol at this experimental stage is a PITA.
