CP Soap Sticks to Teflon!?!?!?!?

[donniej]

A friend of mine makes teflon sheets, so he hooked me up with several yards of adhesive backed sheets. I made a wooden mold and lined it with some of these sheets... when I went to un-mold the next day, it was stuck! Next I tried to make a teflon mold liner... again, the next day when I went to un-mold, it was also stuck! I eventualy got it off but it was much harder than cut up trash bag material or wax paper.

I absolutely can't believe that CP soap sticks to teflon. And when I say "stuck" I mean that when I pried a 4 foot long side of 6" wide by 3/4" thick ply wood off the mold, it started to crack before it would peel off the loaf!

Oh My! :shock: Thanks for the info!

Sorry you had so much trouble..... could you save any of the soap?

I saved the second lot, the first was a total loss... so much so that I even pitched the mold. Next I'm thinking about latex or silicone, but I'll have to actually pay for them!

wow, so sorry that happened, I guess you couldn't have sliced out usable chunks?

do u think the lye reacted with the teflon, and is teflon an aluminum mix?

 

[donniej]

Teflon contains no aluminum. It wasn't that the lye reacted with it, it's that the soap was still soft and mud-like and stuck to it.

Maybe I could have cut the soap out, but it was torn up at that point... and besides, I'm not exactly short on soap

Lye is one of the means people use to remove teflon from cookware, so using it for the purpose you are using it may not work out well unfortunately. Lye does react with teflon, and the amount that's in there when you pour your soap in there is probably enough to get the interesting outcome you're seeing.

While it would be ideal if it works, I fear you may continue to run into trouble. :-(

I wouldn't use teflon for soap.....I don't use it for cooking either. Eventually that stuff breaks down and starts comming off in your food. EEEEWWWW!

I don't know.... I just did a little research on that and got mixed results. Some sites list no data and t
his one says it's good for 50% NaOH...

Maybe it comes in different flavors?

I use a teflon liner for my PVC pipe soaps and it's marvelous.
