How to Make Homemade Soap

You don't have to be an arts and crafts master to learn how to make homemade soap. Depending on what kind of soap you want to make and how much effort you want to put forth, you can find a soap making technique that works for you.

The following are common handmade soap techniques:

Melt and Pour Process
In this process, you will purchase blocks of clear soap base, melt them, add coloring, fragrance, or essential oils, and then pour the melted soap into soap molds. This is also referred to as soap casting. This is the simplest soap making technique and can be done by anyone, including children.

Cold Process
Cold process soap making is more complex. It is the same process that was used before commercial soap was available. There are many variations to this process, but basically you will combine lye (sodium hydroxide), water and fatty acids (always in that order). You must mix the lye and water first, then add the oils, which should have been melted together before combining with the lye-water mixture. Since lye is a dangerous product, you will need to use safety gear such as goggles and gloves. The mixture has to be stirred (you can use a stick blender to speed the process) until the mixture begins to trace, which means it begins to thicken like pudding thickens after you mix it for a while.  The mixture is poured into molds after it begins to trace (this can take up to an hour), then left in the molds for a few days. The soap will need to cure for six weeks before the soap is ready for use. You can add different oils to the mixture for different effects.
