I've started looking at it...is it only HP? I do cp soaps.
Like Shari and the good Gent said, you can make a good one via CP, something along the line of the classic Williams hard puck, which is what my hubby used to use before he started using mine (which I made via CP).
For what it's worth, hubby happily used my CP shave soap for 6 years and would often rave about it to me because he never got a nick or a cut with it like he would with his Williams shave soap and it never dried his face out.
What happened after those 6 years, you ask? Well, that was when our forum got invaded by a bunch of "crazy wet-shaving dudes" (their words, not mine
) from Badger and Blade, who really expanded my formulating horizons as they related to shave soap, and I now make an even better shave soap because of their generous input.
I still use my basic formula for the most part, but I tweaked it to include a goodly amount of stearic acid, which forces me to HP it, but I found that the stearic allowed me to be able to drop the clay from my formula without any adverse repercussions happening to the performance of my soap.......and instead of only using NaOH, I now use a combo of NaOH and KOH.
My new version is much easier to lather than my CP version, it won't dull blades (because no more clay), and it performs and protects my hubby just as well as my old CP version (good glide and cushion and still no nicks or cuts).
Having said that, though, I'm going to try using all-KOH in my next batch to see if it makes for even less
elbow work to get that initial lather going.
For what it's worth, to help you get started experimenting with your own formulating- the bare bones of the CP recipe that satisfied my hubby 6 years contained 60% hard fats and butters (the most of which was tallow), which gave my formula a total palmitic/stearic content of 37%. It was low on the bubbly oils (10%), and it had 30% total soft oils, the majority of which was castor. It also contained 10% of added glycerin, coconut cream as part of my water, 1 tsp. kaolin clay ppo and 1 tbsp. sugar ppo.
Regarding the clay in my old formula: I know only too well that many wet-shavers balk at the thought of anyone using clay (i.e., 'dirt') in their shave soaps, but some wet-shavers do actually like its inclusion. For example, our own Lindy makes and markets a shave soap that sells well, and it has clay in it. And my old formula actually worked much better with
clay in it than it did without
it. The only way I could make my formula work without the clay was to tweak my hard fats to include in lots of stearic acid.
