Why is sodium hydroxide used in soap making?

When mixed with water, sodium hydroxide dissociates completely to just hydroxyl and sodium ions. The hydroxyl ions carry a negative charge, and the sodium ions have a positive one. This influx of ions leads to a strong exothermic reaction, which helps hydrolyze fats in the saponification process to form soaps.
