You are getting awesome advice from all my favorite experts. My 2 cents is I've tried recipes similar to what you posted with great success and also do a 60:40 ratio -- but I've not used soy. I'm all about the bubbly (coconut) but finally reduced it to increase longevity. Two things. I use these pads, https://www.amazon.com/Snowkingdom-...t=&hvlocphy=9019664&hvtargid=pla-872238703885 which keeps soap dry.Ok, would this recipe create a bar that would not melt away? I'm trying to stick to 60:40 on hard vs soft oils while also steering away from lard/tallow (for now) :
Palm 35%
Coconut 15%
Olive 25%
Sweet almond 10%
Shea butter 5%
Soy wax 5%
Castor 5%
Also, now I dissolve 1tsp ppo of sugar to my distilled water BEFORE adding lye and it's a gamechanger with the bubbles.
Sorry to overload you with suggestions. It's hard to experiment and change too many variables at the same time! Anyway, good luck, keep us posted.
And using soy wax will bond you forever to @KiwiMoose -- always with the soy wax, that one.
