The hydrogenated flake form of PKO causes pseudo trace for me if my soaping temps go much lower than 110F (i.e., it precipitates out of liquid suspension if my temps get too cool before the heat reaction of the lye can kick in). As long as I keep things warm enough for it to stay melted/fluid long enough for the heat reaction from lye to kick in, all goes well with me and PKO (or any other hard fat or butter for that matter).

Thank you IL. I can use all the help I can get. So, lard with CO, PKO and temps above 110. Noted.
