    Default Dipropylen vs propylen glicol

    What is the difference? Was trying to google it but didnt find an answer I could understand. Can someone please tell me the difference? But not in chemical stracture, and so... but simple explanation why I should mix a.c. with DPG and not PG. I ask because for some reason they sell PG everywhere but DPG only the big bulk companies sell.
    Thanks

    DPG is better at dissolving in alcohol and dissolving oils, and, due to its higher molecular weight, is substantially better at making the fragrance in a perfume slower to disperse (longer lasting on your skin, and this also means the fragrance can be stronger). Not sure about this but DPG probably evaporates better too.

    If I remember right PG absorbs moisture, which is something you do not want in a perfume. Which is why DPG is used in perfumes instead of PG

    Oh... can someone tell me then, in what ways P.G is better than D.P.G?
    Is it possible its better for water based things or household compounds?

    Do Not Use PG in Alcoholic perfumes, if you can help it. DPG is the proper dilutant.
    PG is for food consumption, and is hygroscopic, it attracts water.
    You don't want hygroscopic materials in an alcoholic perfume.

    I understand that, but if its a room spray that contains water?

    Then you'll need a bacterial growth inhibitor, and likely a solubilizer to allow the attracted new water content to not cloud the solution and or cause mold to grow,
