Household uses for soaps include washing, bathing, and other types of housekeeping, where soaps act as surfactants, emulsifying oils to enable them to be carried away by water. In industry they are also used in textile spinning and are important components of some lubricants. To make liquid soap, we need the following
- 16.5 ounces olive oil
- 7 ounces coconut oil
- 5.5 ounces potassium hydroxide
- 16.5 ounces distilled or filtered water
- 40 ounces distilled
- 3 ounces borax
- 6 ounces distilled or filtered water
- Essential oils, optional
How To Make Liquid Soap
To make a liquid soap, follow the steps below:
- Weigh your olive oil and coconut oil and place them into a pot and place on a cooker using low heat.
- In the jar, measure your water.
- Slowly add the weighed potassium hydroxide, stirring gently as you are adding it.
- Potassium hydroxide reacts slightly differently than sodium hydroxide in water so you may experience some kind of funny noise.
- When the potassium hydroxide is all mixed in and the solution appears clear, add your water/potassium hydroxide mixture to the oils. The temperature doesn’t matter at this point.
- Carefully stir by hand for 5 minutes to be sure all the oils come into contact with all of the potassium hydroxide.
- After 5 minutes, begin to stare with the stick.
- It could take up to 30 minutes to achieve “trace.” (In soap making, trace is normally when the mixture is thick like vanilla pudding, but with potassium hydroxide trace might look more like applesauce.)
- The mixture might look like it’s going to separate, but don’t stop until you have trace.
- Cook on low heat for about 30 minutes with the lid on.
- After 30 minutes, check if it’s separated then stir it back in.
- Check every 30 minutes for 3-4 hours.
