Sodium hydroxide (NaOH), also known as lye, is an essential ingredient in soap making. When sodium hydroxide granules or flakes are mixed with a liquid, a lye solution is formed, which, when mixed with fats and oils, causes a chemical reaction called saponification. The result of saponification is beautiful handmade soap. Making soap is a wonderfully fun and addictive profession.
Instructions for Use: Lye can be dangerous if not handled correctly. Learn how to work with it safely before you get started. Wearing safety gear, gloves, goggles, long sleeves, carefully measure the lye in a glass container. Measure out distilled water or other liquid into a separate container. Slowly pour the lye into the liquid, never the other way around, and stir until dissolved. Let cool and then pour in the oils.
