If you’re looking to make your own soap at home, tallow soap bars are a fantastic choice. They are gentle on the skin, economical, and made from simple ingredients. Here’s a detailed recipe and step-by-step guide to help you create your very own tallow soap bars.

Ingredients

  • Tallow: 1100g
  • Water: 276g
  • Sodium Hydroxide: 149g

Equipment Needed

  • Safety gear (gloves, goggles)
  • Digital scale
  • Heat-resistant container for lye solution
  • Large pot for melting tallow
  • Stick blender
  • Soap mold
  • Thermometer

Safety First!

Before starting, ensure you are wearing protective gear such as gloves and goggles. Sodium hydroxide (lye) is highly caustic and can cause burns if it comes into contact with your skin.

Watch the soap safety guide.

Instructions

Prepare the Lye Solution

  • Carefully add the sodium hydroxide (lye) to the water. Important: Always add lye to water, not the other way around, to prevent a dangerous reaction. Stir gently until fully dissolved. The solution will become very hot. Let it clear up and sit for at least 20 minutes.

Melt the Tallow

  • In a large pot, melt the tallow over low heat until it reaches a liquid state.

Combine and Mix

  • Allow both the melted tallow and the lye solution to cool until they are within 10 degrees of each other. Ideally, this should be around 120°F to 130°F (49°C to 54°C).
  • Slowly pour the lye solution into the melted tallow. Use a stick blender to mix the ingredients until they reach a light trace. This means the mixture will begin to thicken and take on a lighter color.

Pour into Molds

  • Pour the emulsion into your soap molds. Tap the molds gently on the counter to release any air bubbles.

Curing Process

  • Allow the soap to set in the mold for about three days. Once firm, remove the soap from the mold and cut it into bars.
  • Place the bars in a well-ventilated area to cure for at least four weeks. This curing process ensures that the soap hardens and any remaining lye is neutralized, making the soap safe to use.

Final Thoughts

Making your own tallow soap bars can be a rewarding and cost-effective way to produce high-quality soap at home. By following these steps and taking the necessary safety precautions, you’ll have a batch of homemade soap that’s perfect for your skin and the environment.

Happy soap-making!
