| With proper training and knowledge, home made soap or hand made soap should be OK to use. However, with only a bit of knowledge and a little bit of information about how to make so and so in a small scale operation, can I trust their product with proper quality control? What if they have some residual alkali left in the soap? How do I know their alkali do not have heavy metal contamination? I would trust the big company that could loss a lot if got caught doing thing improperly.
