Also, if you don't have to buy glycerin or any of the chemicals you were using before that should cover the slightly higher cost of the palm oil. Do you have any other cheap oils available to you other than palm, coconut, and castor? What about red palm oil/butter? It is very moisturizing and your soap is already a beautiful orange color so you don't have to worry about it discoloring your soap. If I'm not mistaken, don't they produce red palm oil/butter in the Phillipines? It is fairly cheap in the United States so maybe even cheaper there closer to where it is produced? I use it in some of my recipes and it is wonderful. If you can get it allow me to suggest a basic recipe that should give you a very nice bar of soap that should lather well and be very moisturizing.
60% Palm Oil
30% Coconut Oil
5% Castor Oil
5% Red Palm Oil/Butter
When you make the soap, heat all the oils together. Don't add the castor oil after you add the lye water. Heat all your oils just until everything is melted, allow your lye water and your oils to cool to the proper temperature, and add the lye water to the oils, not the oils to the lye water. Proceed as you usually do. Bring the mixture to a light trace and then add your papaya purée. You don't need to put on a fan as you add the purée(you may want to put a fan on the mold after the soap is in it if it gets too hot).The thinner your papaya purée is the better result for your soap. It is best not to have any pulp if you can manage it. The pulp can spoil and ruin your soap. If you like you can message me and I will help you. If you have a great product you will have an edge over your local competition. The color of your soap is very beautiful by the way. I wish you much luck and success.
