Is saponification exothermic or endothermic?

Asked by B P | 18th Mar, 2017, 08:51: AM

Expert Answer:

  • During the saponification process, as the lye (a strongly alkaline solution, especially of potassium hydroxide, used for washing or cleansing) reacts with the various soap making ingredients, soap (and glycerin) is produced.
  • The saponification process itself is an endothermic reaction, meaning that it absorbs heat from the surroundings.
  • This “heat stage” of soap making is commonly called as gel phase.
