Quick Summary

The semiboiled method of soapmaking involves heating fats and an alkali solution in a kettle without bringing the mixture to a boil. This process allows the saponification reaction to occur, transforming the fats and alkali into soap. Once the mass thickens, it is poured into frames to solidify. This method, along with the cold method, is ideal for small factories due to its simplicity and minimal machinery requirements. Both methods, along with the boiling process, are based on the saponification reaction where caustic alkali acts on fats or oils to produce soap and glycerin.123
