To make bar soap, make a lye solution, measure out the oils, and blend the oils with the lye water. Add essential oils and fragrances, pour the solution into a mold, allow the soap to cure, and slice the hardened soap into bars.
- Make a lye solution
Put on rubber gloves and goggles for protection. Measure the desired amount of distilled water into a pitcher. Measure the lye separately. Slowly pour the lye into the water, mixing until the lye is completely dissolved. Place a lid on the pitcher, and allow the solution to cool.
- Measure the oils
Place a glass pitcher onto a scale, and measure out the desired amounts of coconut, palm or olive oil.
- Mix the oils
Place the oils into a soap-making pot, which is part of a soap blender. Heat the oil over medium heat to 100 degrees, and stir the mixture.
- Mix the lye water in
Slowly pour the lye water into the soap pot, stirring with a stick blender.
- Blend the oil and lye water
Turn the soap making blender on in short bursts to completely blend the oils and lye water. The oil and lye water should emulsify to create a thick liquid.
- Pour in additives
Add herbs, essential oils or fragrance. Slowly pour the additives into the trace, using a wooden spoon to blend them. If including a colorant, stir it in after adding the fragrance and oils.
- Pour the soap into molds
Use a steady back and forth motion to pour the soap into the soap mold. Use a rubber spatula to smooth the top. Tap the soap mold on the counter to get rid of bubbles.
- Cure the soap
Set the soap mold in a warm spot. Cover with a towel. Let the soap sit for 24 hours to harden. Remove the soap from the mold, and cut it into bars.
