Two DIY Methods for Making Soap from Scratch

Have you ever thought about making your own soap? Imagine being able to make the scents YOU want. all from scratch!  With a few different methods out there, find out which one is right for you.


Making Soap from Scratch

One major benefit of making soap from scratch is knowing the exact ingredients that go into it. There are two different ways you can make the soap:


Cold Process

This process consists of combining exact mixtures of oil or fat and sodium hydroxide—also known as lye. Because lye is highly corrosive and can burn your skin, you should be extremely cautious and use protective gear, such as gloves and goggles. Once you’ve found the right recipe, you simply follow this 6-step process:

  1. Pour dry lye into water, mixing until it has dissolved completely.
  2. Pour your liquid oils or fats in a separate pot, then add the solid fats or oils, melting them to liquid form.
  3. After reaching the recommended temperature for each mixture, mix the lye with the fats and oils.
  4. After trace is reached, add the desired fragrances, oils, and other nutrients.
  5. Pour soap into a mold and cover.
  6. After it has become solid, slice into equal bars and lay on a rack to cure, flipping every 6 to 8 days.

Depending on the recipe you use, your soap will be ready to use in 3 to 8 weeks!


Hot Process

The hot process is like the cold process, except for the following:

  • You combine the separate containers right away.
  • You turn on low heat once separation begins, stirring continuously to keep from boiling over.
  • Once bubbles are the size of pin heads (about 15-25 minutes), turn heat off, restarting when they are completely gone.
  • Repeat this process until the soap layers bond together to form an even-toned substance.
  • Pour the soap into a mold, smoothing as much as possible

With the hot process, the soap will be cured within a few days. One disadvantage of this method is that it can be difficult to remove the soap from its mold once it has solidified.

If working with lye seems too dangerous, you could always try making soap using less hazardous methods like rebatching or melt and pour—both of which utilize other soaps as a base.
