I ran out of sodium hydroxide and will not get the new order in until Friday. I bought some potassium hydroxide that I haven't used yet, so I can still make soap. Will be making liquid laundry soap tonight with 100% CO, 0% SF, 3:1 ratio and 90% lye purity. This is based on several threads I found regarding liquid laundry soap. What I'm not sure about is additives and didn't find in any of the threads: Do I still need to add citric acid and sodium gluconate to the water before adding the lye? Also, what about a preservative? Is the high pH enough to ward off any microbials after dilution? TIA for any help.
