Sodium Hydroxide is also known as caustic soda and it is a highly alkaline (thus, very corrosive) compound. The mixture of sodium hydroxide with a liquid is known as ‘lye’.

In cold process soap making, sodium hydroxide is added to the water in order to dilute it. The mixing of sodium hydroxide with water results in a reaction that causes the mixture to heat up to about 100ยฐC and fumes to appear. Never add water to sodium hydroxide.

When making cold process soap (and any other time you’re handling lye), wear protective safety gear (safety glasses, gloves, face mask, long sleeves and long pants).ย  Ensure there is good ventilation and there is low humidity in the room. The bowl you’re using to mix lye in is made of stainless steel. Other metals can cause reactions with the lye. If you’re using glass, ensure that it is sturdy and heat-resistant.

Should you come in accidental contact with lye, immediately wash the area with water.

Instructions (for 1+kg worth of soap)

  1. Wear your safety gear as mentioned in ‘Lye Safety’.
  2. Place a large stainless steel bowl on a kitchen scale and weigh 200g of refined coconut oil, 450g of pomace olive oil and 350g of refined palm oil. Set aside.

  3. Preparing the lye solution:
    a) Using a kitchen scale, weigh 325g of Distilled Water/Reverse Osmosis Water and freeze it. You can use ice cube molds or a small Ziploc bag for this purpose.
    b) Place the frozen Distilled Water/Reverse Osmosis Water in a stainless steel bowl.
    c) Using the kitchen scale again, weigh 147g of Sodium Hydroxide in a paper cup.
    btyd) Gently and gradually pour the Sodium Hydroxide into the stainless steel bowl with the frozen Distilled Water/Reverse Osmosis Water. Using a disposable chopstick, stir and ensure that the Sodium Hydroxide has melted between each pour.

    e) Ensure that the sodium hydroxide has dissolved entirely.
  4. Pour the lye solution into the oils.

  5. Gently stir the mixture using a stainless steel whisk. Do not whisk it as though baking.

  6. Once the oils and lye solution have blended, increase the stirring speed.ย After a while, a light trace will form.

    This is light-medium trace, as you can see that the soap batter thick enough to support trailings and drops of batter on the surface.

    *Note: You can use mica powders or natural colorants like clays and activatedย charcoal powder to color the soap. Plant powders like beetroot powder and matcha may change colour during the saponification process, though.
    For 1kg of soap batter, you can add up to 4 teaspoons of powdered colorants once you have achieved light trace.

  7. Pour the soap batter into your mold and firmly tap the bottom of the mold on the table. This is to release any air bubbles.

  8. Place the mold in a large box and lightly close the top. Leave it aside at a cool, dark and not-humid place for 2 days.
  9. After 2 days, remove the soap from the mold and cut it into bars using a soap cutter or a non-serrated knife. Allow the bars to cure at a cool, dark and not-humid spot for 4-6 weeks. While it cures, the water in the soap will evaporate, resulting in a firmer and longer-lasting bar.
