If you love making everyday cosmetics the traditional way, then this simple tallow soap recipe is perfect for you!

Beef tallow is a traditional ingredient that has been used for centuries in soap making. Pure tallow is a great ingredient for soap making because it creates a hard, long-lasting bar with a creamy lather. 

In this tallow soap recipe, we will be using tallow as the main fat, along with other oils to create a nourishing and moisturising bar of soap.

We have also chosen to use our pure essential oils, lemongrass and rosemary, to add some fragrance to our tallow soap recipe. However, you can leave the soap unscented without any essential oils to make the tallow soap even more gentle for sensitive skin.

Read on to make your own soap with our pure beef tallow!

How to make tallow soap

What is beef tallow?

Beef tallow is white in colour and has a solid, oily consistency (similar to coconut oil). It has a neutral scent and a waxy texture. Tallow melts at around 38°C to 48°C and becomes golden liquid.

Tallow is the fat rendered from beef. Our beef tallow is sustainably produced as it is a by product of the meat industry.

In soap making recipes today, most soap recipes use vegetable oils and natural butters. However, beef fat was an essential ingredient in a traditional soap recipe.

Why make tallow soap?

When making soap with pure beef tallow, it adds hardness to the soap bar. It also creates a creamy and conditioning bar.

Beef tallow has amazing moisturizing properties in soaps. Pure tallow soap is often preferred by those with sensitive skin or skin irritation, as it is gentle and soothing.

Making homemade soap allows you to control the ingredients and customize the soap recipe to your preferences, such as adding essential oils or fragrance oils.

  • Mix together and leave to cool.
  • In a separate jug, measure the lemongrass and rosemary essential oils.

Testing the temperature of lye water

4. Check the temperatures

  • Test the temperature of the melted tallow and melted oils mixture, they should be between 35C and 40C.
  • Reheat them or leave them to cool more if necessary.
  • Test the temperature of the lye water, it should be between 25C and 40C.
  • Leave to cool if necessary, but don't reheat the lye solution if it's too cool. Just heat the oils a little more to compensate.
  • When the temperatures are right, add the lye water to the oil mixture.

Blending the oils using an immersion blender

5. Blend until trace

  • With an immersion blender, mix the soap mixture to combine the oils and lye solution.
  • Watch for the soap mixture starting to thicken.
  • Test for a light trace by dripping soap batter on the surface of the soap mixture. If the drips sit on the surface then your mixture has reached trace.
  • When your soap has reached a light trace, add essential oils blend.
  • Mix and blend with a stick blender or spatula until combined.
