I think at least part of the reason the KOH doesn't get as hot is we use so much more water to dissolve it in. With bar soap we use between 30% to 40% water to oils (between 1.96/1 to 2.6/1 water to lye) while we use 50% to 70% water to oil ratio (2.3/1 to 3.27/1) for KOH. This by no means makes it safe… but a lost less concentrated that we use with NaOH. I have been thinking about this… I can’t find anything on saturation points on KOH, will it all dissolve in a 40% solution? If so can it be used for bar soap? I may have to waste some ingredients and try. KOH is definitely nicer to work with:D keep at it grandma, you will figure it out.....I should be making lotion and conditioner:drool: I better go now, a soaper has to have some secrets. I'm leaving this to the experts:D Happy Happy LS Making!
