Sustainable Soap Making: How to Make Soap From Tallow

Table of Contents

The practice of soap making has been around for centuries, and before the widespread convenience of commercial soaps in stores, people would often make their soap at home using animal fats.

Animal fat-based soaps can sometimes be harder on the skin than plant-based or industrially produced soaps, but they provide many unique benefits. For example, using grass-fed pure tallow soap means you are cleaning your body with an organic, non-toxic, and anti-bacterial soap, which has a lot of long-lasting cosmetic and health benefits.

This can’t be said about common soap brands found in convenience stores. In fact, most of those common soap brands contain chemicals, synthetic fragrances, and carcinogenic properties, which increase toxicity in organs when absorbed into the skin.

Homesteaders and preppers embracing healthy and natural living are likely aware that natural and sustainable products come with many benefits. One type of soap recipe you can make easily at home is beef tallow soap. After all, tallow is an affordable and organic food ingredient with lots of known health benefits.

In this article, we’ll discuss what tallow soap is, the advantages and disadvantages of using it, provide our favorite tallow soap recipes, and show you how you can make tallow soap yourself. Continue reading below for more.

What is Beef Tallow Soap?

Tallow soap is a kind of soap made from animal fat – typically from beef or mutton. It’s a sturdy and long-lasting soap that releases a creamy lather. It’s also suitable for most skin types.

We suggest using grass-fed tallow because it will be richer in nutrients like Vitamins A, D, E, and K, which are absorbed into your body, and provide you with more rejuvenated skin. And yes, vitamins can be absorbed through the skin.

Still, you should know that not all beef tallow is the same. The diet of the cow and any type of cow the fat is rendered from will affect the quality of the tallow. Generally speaking, if you use higher quality tallow, it will be less irritating to sensitive skin and rejuvenating properties of the soap. This is why we recommend using grass-fed tallow from pasteurized cows as your main ingredient for soap making.

How to Make Tallow Soap at Home

Our basic tallow soap recipe can be made at home following a simple DIY approach. We will begin by listing out the ingredients and materials; then, we will jump into the soap-making process.


Here are the ingredients you need to obtain to make tallow soap:

  • 10.5 oz beef tallow
  • 9.0 oz organic coconut oil
  • 10.5 oz extra virgin olive oil
  • 4.28 oz lye (aka caustic soda or sodium hydroxide)
  • 32 oz distilled water
  • Essential oils (optional)

Note: If you want to make pure tallow soap, simply remove coconut oil and olive oil from the recipe, and increase the amount of beef tallow in your recipe from 10.5 oz to 30 oz.

Soap-Making Materials:

Here are the materials you need to make soap:

  • Soap mold
  • A large stainless steel pot
  • A wooden spoon
  • A hand blender (or immersion blender)
  • A kitchen scale
  • A thermometer
  • Plastic Wrap
  • Safety glasses
  • Gloves

Note: The rendered tallow should be cooled to room temperature before use. The olive oil and coconut oil should also be at room temperature.

Moreover, lye is a caustic substance, so you need to make sure you handle it with care and follow proper safety procedures when handling it. Finally, note that you’ll be using distilled water to remove impurities in the soap.

Step-by-Step Guide: How to Make Soap from Tallow

To make your own soap, you can follow the DIY guide below.

1) Prepare Your Equipment

Before you start making your soap, ensure you have all the necessary equipment, ingredients, and safety gear. Then, get changed into a long sleeved-outfit and pants to protect your skin from splatters.

2) Prepare the Lye Solution

Go to a well-ventilated area and carefully measure about 12 ounces of lye and slowly pour it into 32 ounces of distilled water. Be sure not to pour the water into the lye since this can cause an adverse chemical reaction.

As you pour the lye, you’ll notice that the solution will heat up quickly and release fumes. So, you’ll want to double-check that you’re in a well-ventilated area and that you’re wearing safety gear.

Stir the mixture using your wooden spoon until the lye is completely dissolved. The solution will quickly become hot, so you’ll want to wait until it cools down to around 100°F (37°C). Then, label the container as “lye” and store it in a safe place out of reach from children and pets.

3) Prepare the Tallow and Oils

Mixing Tallow SoapIn a big stainless steel pot, melt about 3 pounds of beef tallow on low heat. The melting point of pure tallow is 112-120°F (45-50°C). Remember, the tallow should be rendered and cooled to room temperature before use.

Once you’ve fully melted the tallow, add a pound of coconut oil and a pound of olive oil to the pot. These oils should also be at room temperature. Then, stir the mixture until all the oils have melted and blended together.

4) Combine the Lye Solution and Oils

Once you’ve cooled both the lye solution and the oils to about 100 degrees Fahrenheit, carefully pour the lye solution into the pot that holds the oils.

Use a hand blender to blend the mixture until it reaches a light trace, which is the point wherein the mixture thickens and leaves a trail on the surface. This process of combining lye and oils – sometimes referred to as saponification – turns the oils into soap.

5) Add Essential Oils or Other Additives

In this case, popular essential oils that you could use in your soap include peppermint, tea tree, lavender, and eucalyptus.

6) Pour the Mixture Into a Mold

You’ll then want to cover the mold using a plastic wrap or towel to keep it warm, then allow it to sit for at least a day. During this time period, the soap will continue to heat up.

7) Cut and Cure the Soap

After about a day, remove the soap from the mold and cut it into smaller bars using a sharp knife or a soap cutter. Put the bars on a drying rack or any other suitable surface and let it cure for about a month.

While the soap cures, it’ll harden. You shouldn’t skip this step since this step is what results in a gentle and long-lasting soap.

8) Enjoy Your Soap

Once your soap has cured, you’re ready to use it.

Store the soap in a cool and dry place and enjoy its nourishing and moisturizing properties. This homemade soap makes an excellent gift for friends and family, too.

Note: This recipe makes a large batch of soap, so you might want to cut the soap into smaller bars.

9) Clean Up and Store Leftover Ingredients

After you’ve finished making your soap, it’s crucial that you clean up properly and get rid of any harmful substances. Start by wiping down all surfaces and equipment with paper towels to remove all traces of lye or soap thoroughly.

Next, wash all your equipment using hot water and dish soap. Lastly, store any leftover tallow, oils, or other ingredients in a cool and dry place.

Pro Tip: Troubleshooting

If you run into any issues while making your tallow soap, there are a few fixes you can try.

For example, if your soap doesn’t harden properly, it’s likely you didn’t leave the soap to cure long enough. On the other hand, if the soap is too hard or crumbly, it may be that you left it to cure for too long.

Disadvantages of Using Tallow Soaps

Although tallow soap is excellent, using it does come with a few drawbacks. These include:

  • Scent: Although this is a preferential thing, you might not like the natural smell of tallow soap. It’s often described as animalistic or musky.
  • Environmental Concerns: Despite tallow soap being sustainable, there are concerns about the environmental impact of using animal products when making soap. These concerns revolve around the potential for pollution from runoff and the ethical implications of using animal fat.
  • Allergies: If you’re allergic to tallow or other animal products, you may end up with irritated skin or other negative symptoms after using tallow soap.

All in all, tallow soap is an excellent option if you’re looking for a natural and sustainable alternative to commercial soap. Although there are some potential disadvantages to using tallow soap, you may find that the benefits outweigh any drawbacks.
