You can add shea butter to any CP recipe by just subbing some of the oils already included - REMEMBER though to run the new mix through a lye calculator first!!!
I love a combination of Coconut (76 degree), Olive, Ricebran & Shea Butter as a basic recipe. I use grams so here it is in weight:
CO 300g
OO 300g
RBO 200g
SB 100g
I discount my lye (superfat) at 6%, so use 127.5g
For lye solution I prefer 30%, so 297g water.
If you have a recipe you are thinking of already, to add SB I would replace some of the hard oil with it. I use it instead of palm oil for example.
I am sure you will get lots of tips and recipes. Enjoy your soaping .....it is so much fun!!
