Transcript:How to Make Liquid Soap
Hi, this is Mike Lambert with About.com and in this video you'll learn how to make liquid soap using the instructions from About.com's Candle and Soap Making site.
To Make Liquid Soap, You'll need:
16.5 oz. sunflower oil
7 oz. coconut oil
5.5 oz. potassium hydroxide
16.5. oz. distilled water for the lye solution
40 oz. distilled water to dilute the soap paste
2 oz. of boric acid.
You'll also need some utensils like a double boiler or crock pot, a thermometer, measuring cups, a stick blender and safety equipment, like gloves. Personally I like my soap very natural, so I prefer not to add any fragrance or colorants. Ok, now that you have everything, let's get started.
Mix the Soap Solution until Trace
First, you have to make your lye solution. To do this, mix the distilled water with the potassium hydroxide. The potassium hydroxide will react with the water and heat up quickly to about 200 degrees. Set the solution aside in a very safe place while you heat up your oils. Mix the oils together and heat them up to about 160 degrees. Stir the oils and lye together, then start blasting it with the stick blender. It will take around 30 minutes to get to trace.
Dilute the Paste in Water
After this you'll need to be patient, waiting about three to four hours and stirring every 20 to 30 minutes. Over the three to four hour period, the soap will pass through various stages. You'll know the paste is finally ready when you see it has reached the translucent Vaseline stage. At this point, it's time to dilute the paste. Take the remaining 40 ounces of distilled water and bring it to a boil. Add the water to the soap paste and stir it up a bit with a spoon. Turn off the stove and place a cover on the pot and wait. As it may take quite a few hours, You may want to find a good book or even head to bed as it dissolves.
Neutralize the Soap with Solution
After the soap paste has dissolved in the water, it's time to neutralize the soap. Heat the soap back up to around 180 degrees. In a separate container, mix the neutralizing solution by adding two ounces of boric acid to eight ounces of boiling water. For this recipe, we'll be adding around two ounces of neutralizing solution. Slowly add the neutralizing solution and stir it as you add it. Add it a half ounce at a time.
Allow Soap to Particles to Settle
Let the soap cool and pour it into a jar or bottle. After about a week or so, all the insoluble particles should have settled to the bottom of your jar. From there, just transfer the soap to a container like this without disturbing any of the settle particles at the bottom. That's it. Thanks so much for watching.
