Soapmaking — Scientific

Soap is created through a hydrolysis reaction. The alkali (typically sodium hydroxide for hard bars or potassium hydroxide for liquid soap) breaks the ester bonds of triglycerides (fats), releasing fatty acids that then bind with the alkali to form salt—which we call soap.

: The hydrophobic tails attach to grease and oil, while the hydrophilic heads stay in the water. This forms a micelle , surrounding the dirt and allowing it to be rinsed away. Advanced Concepts for Soapmakers Scientific Soapmaking

At its core, is the study of saponification —the chemical reaction between a fat (oil) and a strong alkali (lye) to produce soap and glycerin. While craft soapmaking often follows "recipes," a scientific approach focuses on stoichiometry, molecular structures, and analytical testing to create precise, high-quality bars.
