DIY: How To Make Goat Milk Soap


Many people are still washing their skin with soap made with water. Switching to soap made with raw goat milk can truly benefit your skin’s health. Goat milk soap is wonderful for people with dry or sensitive skin, or conditions such as eczema and psoriasis. It is also perfect for healthy skin that wants to stay that way. Unprocessed, raw goat milk fresh from the farm contains the following benefits.

In this article we will show you how to make your own goat milk soap.

Learning how to make goat milk soap doesn’t have to be complicated. Follow our step-by-step goat milk soap recipe and see for yourself. I will demonstrate one method for achieving pure, white goat milk soap, by using a water discount and adding the milk at trace.

What Equipment Do You Need:

Large mixing bowl of #1 or #2 plastic, glass, or stainless steel — NO ALUMINUM. (It will react with the lye!); two smaller containers made of #1 or #2 plastic, for measuring water and lye; a spatula, spoon or whisk for stirring oils, and another for stirring the lye mixture; a mold for the finished soap. Optional: small glass or stainless steel container for measuring essential or fragrance oils.


  • 22 oz(623 g) olive oil
  • 8 oz(226 g) coconut oil
  • 5 oz(141 g) chilled water
  • 5 oz(141 g) canned goat’s milk
  • 2 oz(119 g) lye (sodium hydroxide)

Step 1

At least a day before you plan on making soap, weigh out 5 ounces of canned goat’s milk, pour into an ice cube tray and freeze. Because canned goat’s milk is usually evaporated and double strength, we’ll end up diluting it later with an equal amount of water.

Step 2

When you’re ready to make your soap, place the frozen cubes of canned goat’s milk into a heat proof plastic or stainless steel pitcher. Pour 5 ounces of chilled water on top of the cubes.

Wearing proper safety gear – gloves, goggles and long sleeves, slowly sprinkle a bit of lye in at a time, stirring well after each addition. This will take several minutes. Make sure that the lye is fully dissolved before you proceed.

The mixture may turn orange or yellow and smell weird – like ammonia – but that’s all perfectly normal. Avoid directly breathing in the fumes. I like to work in my kitchen sink, with the window open for fresh air.

At this point, your lye mixture will probably be around 115 degrees Fahrenheit (46 degrees Celsius). It’s okay if it’s a little higher or lower.

Step 3

Set the lye mixture aside for a few minutes.

Heat the coconut oil in a small saucepan – first until melted, and then an extra three or four minutes until it’s hot. Pour it into the container you’ll mix your soap in and add the olive oil. The combined oils should be around 100 degrees F (37 degrees C), but it’s okay if it’s higher or lower by ten degrees or so.

Line your mold. For this batch, I used a glass 8.5 inch x 4.5 inch loaf pan (a 9″ x 5″ will work too) lined with a super cheap, unscented trash bag. You can also use parchment or freezer paper. (Wax paper is too flimsy and tends to tear and stick, so don’t use that.)

Step 4

Now, it’s time to mix everything together!

Carefully (wearing gloves, goggles & long sleeves), pour the lye solution into the soap mixture.

Using a stick (immersion) blender, stir the oils and lye together. Since this soap is high in olive oil, it will probably take a while longer to reach trace – perhaps up to ten minutes. Trace is when the soap batter is thick enough to leave a faint impression when you drizzle a bit over the top of itself. (If you hand stir it will take a long, long time – possibly hours to reach trace. I don’t recommend a hand mixer either.)

Step 5

Pour the soap batter into the prepared mold. Usually you can put milk soap in the refrigerator overnight, if you’d like it be a lighter color. Since canned milk has already been exposed to high heat during processing though, I just left this batch uncovered at room temperature.

Step 6

Let the soap stay in the mold for 24 hours.

The next day, you’re ready to unmold and slice into bars. Using the 8.5″ x 4.5″ loaf pan, this batch made 7 full bars, plus two ends that we’ll still use – they just aren’t as pretty for gifting.

Let the soap cure in the open air for at least four to six weeks. Since this soap is pretty high in olive oil, it may take longer to firm up. High olive oil soaps have a long shelf life and improve with age.
