How this bar will behave

The dark band is the range most balanced bars fall in. The dot is your recipe: green when it sits inside the range, orange when it falls outside. Values are estimated from typical fatty acid profiles of each oil.

Formulator's notes

    Before you make it: always run your final recipe through a lye calculator such as SoapCalc to get your exact lye and water amounts. Weigh lye to the gram and wear goggles and gloves.
