Every time I have used Great Value Olive Oils from Wal-mart, my soaps develop DOS (Dreaded Orange Spots) which are commonly found in soaps when the oils are old and begin to go rancid. I have tried it many times hoping that it was just a bad batch and every time it only takes 30 days. Sometimes only 14 days to develop the DOS. The soaps are discoloring before they are properly cured. I have tried lowering the superfat and tried with only 100% olive oil with no other oils or scents. I have tried gelled and ungelled. I have tried the same thing with oil from another source and only the Great Value Olive Oil causes this problem for me. The bottom line is that I really question the freshness of this oil. If it is causing this in soap, I can't imagine it would be any better for human consumption. I would pick another brand.
