Alaiyna B's Tutiorial on Making LS with Goat Milk
That's a good tutorial.
Although it can be made with just water and just KOH. I use powdered GM added to the warmed oils before adding the lye solution. If you use 50% coconut oil or more, there's no need to thicken with HPMC and it can be diluted at 40% soap to 60% water.
Combine when oils are
160°F (71°C) and lye solution at
140°F (60°C). Stir by hand, then SB, on and off, to HARD trace (10-15 minutes) over MEDIUM to LOW heat. Maintain
160°F (71°C) while bringing to trace.
I have made LS with GM using my own formula. One thing I can assure you of is that you will get a brown sediment on the bottom of the diluted LS. I dilute the whole batch all at once, slowly, on the range top in a large stainless steel pot to accommodate all the liquid. I sequester for a full 2 weeks before removing the sediment to be sure I've got it all.
