Goats Milk Soap Recipe

Goat milk soap recipe

August 16, 2023

If Cleopatra bathed in milk to keep herself beautiful then it’s good enough for us! For thousands of years milk soaps have been incredibly popular.

They feel luxurious on your skin and are bursting with moisturising properties from the fat content of the goats milk as well as being packed full of fatty acids, nutrients and glycerine. 

Why make goat milk soap?

Goat milk soap is an absolute classic. It is widely used by people with sensitive skin, and many people report that it helps their eczema.

To help keep the goat milk soap as gentle as possible we haven't added any essential oils. Some essential oils can often be the cause of irritation for people with sensitive skin.

However, if you would like to add essential oils then we'd recommend adding using around 25g in this recipe.

How to use goats milk for soap making

Usually, cold process soap recipes are made up of water, oils and sodium hydroxide. However, when you're making goat milk soap you replace the water with goats milk.

The more goat milk you use the creamier your bar. For our goats milk soap recipe we have gone for 100% water replacement for extra luxury!

We're using powdered goat milk in this recipe because it is much easier to handle than fresh goat milk. You can add it directly to the melted oils, rather than having to freeze it into cubes.

Safety Note: Cold process soap making involves handling sodium hydroxide. You must wear gloves and goggles at all times. It is a caustic product and will burn.

In the event of getting it on your skin, rinse well with plenty of plain water. If it is splashed in the eyes, wash with water and seek urgent medical attention. Keep away from pets and children at all times.

Testing oil temperatures for soap making

3. Check the temperatures

  • Test the temperature of your melted oils, they should be between 35C and 40C.
  • Reheat them or leave them to cool more if necessary
  • Test the temperature of the sodium hydroxide solution, it should be between 25C and 40C.
  • Leave to cool if necessary, but don't reheat if it's too cool. Just heat the oils a little more to compensate.
  • When the temperatures are right, blend the powdered goat milk into your oil mixture.
  • Add the sodium hydroxide solution to the oil mixture
