I use caustic soda to
I use caustic soda to make soap. I am currently using the beads, and although they are cheaper, they are more of a hazard, as they clump together and create static electricity. So, now I am switching over to flakes. These flakes are the high purity I need, and at a great price. Shipping was extremely fast too, but I attribute that to the fact that I ordered early in the morning, and I am only 3 hours away by car from their facility in Taylor, Texas.
