yogurt

Hello! How do I go about making cold processed yogurt soap? When do I add it? How much do I add (PPO)? What does it do to the soap? Anything I should know before making yogurt soap to anyone who has already made yogurt soap? Thanks!

Hot Processors - Can adding powdered goat milk at the end of cook increase fluidity similar to yogurt? I'm up for trying it, but wanted to ask if anyone knew or has tried it. TIA
