after I posted that, I was assuming that's what you meant? As long as the bottle says 100% lye, it's ok to use for soapmaking. I get my lye at Menard's and Rooto is the brand they carry.
rooto is what i use all the time i used the powdered -- my local hardware store carries it just for me they also carry the liquid form, but have never tried it.
I use Rooto all the time. Actually just picked it up last night at my local Ace Hardware. You have to ask for it because it is not out on the shelf. I always take in a few bars of soap for them and the manager will mark it down to the lowest possible price for me. Got it for 3.50 a bottle yesterday (1 lb each)
