I add the stearic acid and PS80 to my canning jar along with the paste and set aside momentarily. Then I combine the water, sodium lactate, and EDTA to a small pot and heat to boiling, then I pour it immediately into my jar of paste/stearic/PS80 before covering and setting the jar in my boiling water bath.
Welcome Robzanc. :wave: Yes- it does change the 25% lye concentration, but I adjust for that by adding less water during dilution time.I've searched through this thread but couldn't find an answer to the following:
Regarding the easy water/glycerin method for dissolving KOH, the instructions are to dissolve KOH in an equal amount of water and then add the full recipe amount of glycerin. However, doesn't this now change the 25% lye concentration of the original recipe?
Couldn't you dissolve the KOH in an equal amount of water and then add 2/3 glycerin so that you maintain a true 25% lye solution (aka 3:1 ratio)? The only disadvantage is your final soap paste will have less glycerin as compared to the original recipe. To account for this, can we add additional glycerin during the paste dilution stage?
In the end, the soap comes out the same consistency whether you keep to a 25% concentration up front, or use a lesser concentration up front, just as long as you make sure to add less dilution water if you used a lesser lye concentration up front.IrishLass said:
