well the one i have i believe it the HO, i got it at walmart but when i was reading about the HO one it said that if there was 2 ingredients together on the label it was the HO version ( cant remember the 2 ingredients ) and the one i have has them both listed together. so i am assuming i have the HO. ill be trying this recipe tomorrow. i didnt try it first cuz i didnt have the pko flakes then. but this recipe has such awesome reviews it should be one kick ass soap! i hope i like it! i will be adding the silk to the lye water, and sugar as well cuz im doing hp. expect pics sometime this weekend
