I have always wanted to make soaps. So I did some research and found a easy cold process soap kit to start.  If you love easy soap making. This post will show you how to make a cold process soap recipe. Once you make this soaps its perfect for any gifting ideas.

Cold process soap is made by combining oils and sodium hydroxide lye, which causes a chemical reaction called saponification. In the process, you get to choose the oils, scents, colorants, and any other ingredients.

Why Cold Process Soap

The first soap makers were Babylonians, Mesopotamians, Egyptians, as well as the ancient Greeks and Romans. All of them made soap by mixing fat, oils and salts. Soap wasn’t made and use for bathing and personal hygiene but was rather produced for cleaning cooking utensils or goods or was used for medicine purposes. Much of this process they used is very similar to cold process soap making.

Supplies for Cold PRocess Soap

If you are serious about soap making even as a hobby, it’s worth while to have these equipment solely for soap making and nothing else. It’s because of the Lye ingredients which is toxic. I have research all the equipment brands and they work well. Here is a kit I used that has all the oils. I substituted the palm oil for lard.

  • Scale
  • Infrared thermometer
  • Stick blender
  • Glass containers
  • Spatula
  • Stainless steel spoon
  • Sharp
  • Knife
  • Goggles
  • Gloves
  • 10 inch soap mold.
  • Oils

Oils Needed for Cold Process Soap

  • 13.5 oz. Olive Oil
  • 9 oz. Coconut oil
  • 1.5 0z. Caster oil
  • 2 oz. Fragrance oil
  • 9 oz. Lard! (The recipe that came with the kit was palm oil, palm is bad for the environment so I substitute it with lard).
  • 10. 9 oz.Distilled water
  • 4.6 oz. Sodium hydroxide lye
  1. Weigh the oils in a glass measuring container, make sure you take the weight off of the container first and use the true weight. Very easy to reset the scale. Put all the oils in a 64 oz. glass container. Set aside.

2. With gloves and goggles weigh the lye in a glass container, weigh the water and oil in separate container as well.

3. With the gloves and goggle on prepare the lye mixture. Warning! Add the lye to the water not the other way around. It will cause a volcano and splash everywhere. Lye is dangerous for the skin and eyes. Do this part outside. Trust me it’s easy and safe if you follow directions. 

4. When the lye is added to water it becomes hot. With the thermometer cool down the lye to 130 F and the oils need to be warmed up to 130 F as well.

7. Add the fragrance into pudding. Blend well again.

8. Once it is blended, pour into 10 inch silicone loaf. Let harden for 2-4 days  (This is where the soap making process is magical)

cutting the soap

 After 3 to 4 days check the soap. Once its hard, cut into 1 inch thick using that sharp knife. Afterwards you have to cure for 4 weeks in a dry area. Keep the soap uncovered. This is art of natural soap making. After I did it I felt so happy that it came out perfect. The key is that you have to use the scale and thermometer to get perfect. Otherwise it can get a blotchy brown.
