  • You should first measure the components and wear safety equipment
  • Then set the slow cooker to low
  • Put the coconut oil in a slow cooker.
  • Wait until it melts, prepare the lye.
  • Then you slowly add the lye solution to the water. You do not add water to the lye solution.
  • Continue to carefully stir the solution with a spoon if you want to add lye. At this point, it will become hot and smoky
  • You set the lye solution aside and let it cool for 15 to 20 minutes.
  • Measuring the oil, once the coconut oil is completely melted, you have to add the olive oil. This step is completely hidden
  • Checking the temperature of the oil with a candy thermometer. Because you feel the oil has reached 120 to 130°F (49 to 54°C), then place the immersion blender on the side of the slow cooker.
  • Just gently pour in the lye to avoid splashing. Continue stirring.
  • Set the blender to low to stir the mixture in a circular motion.

Note to keep the blender immersed in water to avoid creating air bubbles. Continue mixing and stirring for 10 to 15 minutes until the soap reaches the mark In the end you will see the oil and lye thicken like pudding

Cover the slow cooker on low for 50 minutes. If you look for the mixture frothy, stir gently. Turn off the slow cooker, then let the mixture cool until the mixture drops below 180°F (82°C). If you like, add essential oils and colorants and mix well.

Quickly pour the mixture into the soap mold and smooth the top with a spatula. In particular, tap the mold on the work surface to remove air bubbles. If you like, put dried herbs on top.

5. Make soap mold

Standard soap bars are 3.5 to 4 ounces. For the recipe that will make about 30 ounces. This all depends on how you cut the soap (7 to 10 bars). How to make a soap mold:

Before pouring the soap into the mold, let it sit for 24 hours.

When it cools, carefully remove the soap from the mold.

Then cut into bars with a cutter or soap knife. Please use only single soap mold because it is easy to open

At the same time, soap can be used at this point or can be left to dry for an additional week. Because the longer the soap is left on, the more hardness and quality will be improved.

If the soap is hot treated, it will have a rustic and homemade look. If you like delicate bars, consider trying the cold treatment.

However, homemade soaps tend to have a milder fragrance than traditional store-bought soaps. So you can add more essential oils for a stronger smell, but it is very expensive, especially when you use expensive oils

6. Soap making tips

Should choose a place to make soap that is ventilated when making lye solutions.

Pay attention when lye enters the water, avoid touching the container with bare hands or breathing the fumes.

Be careful not to add lye if the base oil is above 180°F (82°C).

You can also use individual soap molds, no cutting required.

When using essential oils, pay attention to the amount of drops as it will largely depend on the quality of the essential oil and personal preference. You can start with 20 drops for a lighter scent and 30 drops for a stronger scent.

Fragrance oils are usually more concentrated, so you can start with fewer drops.

7. How to choose soap ingredients

Some basic ingredients of soap base include:

  • Animal fat or vegetable oil
  • 100% pure lye solution
  • distilled water
  • Skin-safe fragrance oils (optional)
  • Colorant (optional)

The use of fat or oil is up to preference, usually soaps are made with animal fat, but nowadays vegetable oils avoid killing animals. In addition, depending on the type of oil, the hardness and foam of the soap will be different.

Water: is the essential city. Because it is used to make alkaline solutions in combination with oils. Because water simply assists the oil and lye in the saponification process. Once the soap has solidified, the water has evaporated. We recommend using distilled water.

Besides, some other liquids for your reference:

  • tea
  • coffee
  • beer
  • goat milk
  • coconut milk
  • Fragrant

Maybe soap doesn't need scent to clean skin. But to scent the enemy's body you can add a pleasant smell, by using essential oils or aromatherapy. Essential oils are mostly derived from plants, and they can be combined to create custom fragrances. Remember, fragrance oils are synthetic oils, when choosing fragrance oils, look for ones that are safe for the skin.
