SOAP!
I've been using this in CP soap for the past 6 months and it does make a very nice conditioning ingredient.  My only bother was that I bought the 3 pound amount which arrived with a big leaky crack in the bottom of the container.  Fortunately it was inside another plastic bag or there would have been quite a mess.  I'm thinking I'll buy the smaller size this time and hope the container doesn't crack again.  The small container is Prime supported anyway and I won't have to pay the shipping charge.  Spoiled, Prime lover, that I am.
