    source for polyproplyene glycol

    I would like to get a source of not too pricey glycol to mix my pyrocat A in.

    About half a gallon would do for quite a while, mixing the A in glycol and B in water.

    Can't seem to find a source other than some silly price for 100cc.

    Help would be greatly appreciated

    Propylene glycol is pretty common stuff, used in soaps, cosmetics, even to treat cows for ketosis (whatever that is).

    Befriend a farmer, he's probably bought some from his local Feed & Farm Supply for about $30 per gallon.
    Any local soap making artisans nearby?

    Or... get it at a resonable price at:

    The title says "polypropylene glycol" -- just to make sure, that's NOT what you want. There is a substance called polypropylene glycol but it's not of much use for mixing darkroom chemicals.

    What are Diary Cattle. Cows writing in books every day? I found a tree where someone had carved "moo". Guess this explains it.

    I recently bought a small amount of propylene glycol (not the same but related) from PF. I needed something that would flatten film (some rare films have no backcoatings and curl like corkscrews). Propylene glycol was the ingredient in Kodak's print flattener.

    In the process of looking for this stuff, I called a heating/cooling company and indeed, he could have sold me some if I had wanted enough for him to bother with opening a 55 gallon drum. It was used in a certain kind of cold humidifier to keep the moisture content of the air at a 70% level. I didn't need enough, so I got it from Montana.

    Mixing up a batch of the stuff with photo flow added did work. Worked very well. The solution does not keep however. Apparently, it is a sort of urschleim; weird stuff grows in it, and I suspect that after enough time, lizards will be crawling out of it.

    I don't know if PPG is sold by heating/cooling contractors, but it might be worth a shot.
