At its core, is the study of saponification 鈥攖he 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. The Core Chemistry: Saponification

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鈥攚hich we call soap. At its core, is the study of saponification
For those looking to move beyond basic recipes, these concepts from Scientific Soapmaking by Kevin M. Dunn are essential: The alkali (typically sodium hydroxide for hard bars
: Each molecule has a hydrophilic (water-loving) head and a hydrophobic (water-fearing/oil-loving) tail .
