Recipes
Used http://www.soapcalc.net/calc/SoapCalcWP.asp for calculations
Roughly
fat + base ( NaOh or KOH ) = Fatty Acids + Glycerol i.e. soap

- A great Piece on "Sap Values" http://en.wikipedia.org/wiki/Saponification_values
- Handmade soap makers who aim for bar soap use NaOH (sodium hydroxide). Because saponification values are listed in KOH (potassium hydroxide) the value must be converted from potassium to sodium to make bar soap; potassium soaps make a paste, gel or liquid soap. To convert KOH values to NaOH values, divide the KOH values by the ratio of the molecular weights of KOH and NaOH (1.403).
