WSP is a bit stingy on giving up their ingredient lists, LOL! I tried asking the percentage of glycerin in a particular M&P base, and they said sorry that's proprietary. Darnit. That's their standard answer for a bunch of stuff.
At the moment, I only do M&P, though soon I might get the chance to venture into CP cuz we just moved and our new house has a seperate office/back house that I might be able to use to work with and store lye - my hubby won't let lye in the house because we have an 18-month-old. Oops, I sure got off track there - BACK to the question!
Since I've only done M&P so far, I measure with teaspoons and tablespoons - so this might not help much at all - but I was using 1/2 tsp per pound for the Energizing blend and 1/4 tsp per pound for the Euporia blend. So ROUGHLY, I was probably using .5% for the energizing and .25% for the euphoria, but I never weighed them.
