How to Make Goat Milk Soap – a natural cold process recipe

Goat milk soap is a classic handmade soap that is sought after for a reason.

The milk added to soap makes such a moisturizing soap that it’s a traditionally THE soap to buy from artisan soap makers. It can make a hard soap bar that’s long lasting, especially when made with tallow, and so wonderfully conditioning for the skin that it can even double as a shampoo bar as well!

Why Make Goat Milk Soap

I mentioned above how goat milk soap is moisturizing. Goat’s milk is even better is soap than cow’s milk, because it’s higher than beta-casein (fat content). This raising the superfat content in the soap and therefore increases the moisturizing content.

Goat milk also has Vitamins A, B6, B12, E as well as minerals like magnesium, potassium, and selenium. These do not get destroyed in the soap making process. Remember that your skin is the largest organ of your body. What you put on your skin matters.

Got milk is also full of alpha-hydroxy acids. Alpha-Hydroxy acids soften skin by helping to break the bond between dead skin cells. This helps to remove dead skin cells from the surface of your skin while you wash, making your skin look younger and more healthy.

Lastly, goat milk soap is naturally antibacterial. Those with acne prone skin do well with a goat milk soap because it’s not overtripping, but cleanses really well, moisturizes, and then helps kill bacteria better than other soaps.

How to Add Goat Milk to Soap

If you are new to soap making, you may not know that anything with herbs or sugars, even natural sugars like those found in milk, can cause scalding when lye is added.

Typically, after the water and lye are weighed and taken outside, the lye is slowly added and stirred until dissolved. When spirulina, aloe, and other herbs are added to the water before the lye is added, it results in a dark lye water. This is actually a benefit when it comes to adding color to soap. Lye water can deepen colors, which is why some herbs are added to the lye water directly instead of to the oils or at trace.

But when adding lye to milk, the milk can scald and separate. This stinks, literally. If this happens it’s not the end of the world. The scent can be covered up with essential oils for scent and the coloring will be a deep cream to creamy brown color. But its better not to scald the milk. There are ways to do this!

3 Ways to Add Milk

1. Add powdered goat’s milk to the oils. Instead of using goat’s milk for the lye water, use the same amount as water and make your lye water as usual. Then, add powdered goat’s milk to the oils and blend well before adding the lye water as you usually would with a cold process soap recipe.
2. Reduce the amount of goat’s milk in the recipe and add water instead. So, instead of adding 100% goat’s milk, add 30% goat’s milk directly to the oils and use the other 70% as the water that you will dissolve the lye into. If you want to use mostly or all goat’s milk, then use the next method.
3. Freeze the goat’s milk! Ideally you’ll want to make it almost frozen, but not fully. That slushy stage. Then when you add the lye to the goat’s milk, it will heat the milk, but not be able to rise the temperature to a degree that will actually scald it.
