Retired and using my years of experience as a chemist, due diligence was taken using scientific methods to analyses a score of different oils in a multitude of combinations.  It has been a five year journey.  The goal was to achieve the highest quality soap that could be made.  Sixteen different qualities and values were evaluated with cleansing, creaminess, and conditioning being at the top of the list. The cost of raw material was not a factor in determining ingredients. I did produce a soap that met my goals.
