Soap is a product that's been around for thousands of years. It's made using a recipe that combines lye with oils and butters.

The chemical reaction between lye and fats produces soap and glycerin. This reaction is called saponification.

All soap contains lye, but not all products called soap are true soap. Some are made with detergents and other chemicals.

True soap, also known as lye soap or natural soap, is created by mixing lye with oils and butters. This mixture is then heated to produce the soap.

There are different kinds of lye, including sodium hydroxide and potassium hydroxide. Sodium hydroxide is used to make solid soap, while potassium hydroxide is used to make liquid soap.

After the saponification reaction is finished, there is no lye left in the soap. Only soap and glycerin remain.

When making lye soap, it's essential to use 100% lye, specifically sodium hydroxide, to ensure the soap turns out right.

You'll often find lye packaged as drain cleaners, like Roebic or Rooto, but it's best to get it from a soap making supplier for the best results.
