Transcript:How to Make Soap Using Goat MilkHi, I'm David Fisher for About.com. One of the most popular additives people put in their cold processed soap is goat's milk. It has extra proteins and vitamins and caseins that are actually really good for your skin. Making soap with goat milk is not too hard but it takes a couple extra preparations steps. Today I'm going to show you three different ways to use goat's milk in your soap batch.
Fresh Goat Milk in SoapThe first way that we're going to incorporate goat's milk into our soap, is to use fresh goats milk. I know that this doesn't look fresh, it's actually frozen. What I did is I took the milk and put it into a large ziploc bag and put it into the freezer to lay it flat. We'll use this frozen goats milk incorporating into the soap.
Put your lye pitcher in a large bowl of ice water. This ice bath will keep your solution cool as you're mixing it. Then we're going to substitute the goat's milk for the water in our lye solution. Break off the amount you need and put it into the pitcher, and then measure out the lye you'll need for the recipe. When the goat's milk has warmed up just a bit so that it's slightly slushy, start adding you lye, bit by bit, very, very slowly. Wait several minutes between adding any more lye. Stir a little bit. Wait a little bit.
What will happen is that as the lye reacts with the milk, it's going to start to warm up. This is what you don't want. The hotter it gets, the more the color will shift. As a guide, don't add any more lye if the temperature is over 90 or a 100 degrees. Keep adding tiny bits of lye to the mixture until you've added all the lye for the recipe. For a normal batch of lye-milk this will take between 10-15 minutes. Once the lye is mixed with the milk, make your soap like you normally would, using the milk-lye solution in place of your water-lye solution.
Soap With Evaporated Goat MilkNow if you don't happen to have several readily milk-able goats in your backyard, or a friend with some goats, you may have to use canned or evaporated goat's milk. Now the thing with the canned evaporated goat's milk is that it's usually double strength - so we'll have to deal with incorporating this into your soap just a little differently.
Most of the once you'll find at the grocery store are double strength canned goat's milk. What you'll do for your recipe you'll measure out half the amount of water that you'll need for your recipe. So for example, this recipe that I'm using today uses 7 oz of water. So I've put in 3.5 oz of water in this pitcher, and set aside 3.5 oz of the evaporated goat's milk. Then using the half amount of water add the lye and stir carefully. It's going to take a while to dissolve because this is a double strength lye solution. And not that you're not always careful with your lye solutions, but be doubly careful with this lye solution. If it's not quite dissolving, you can add a couple of tablespoons of water, a bit and a bit. But you do want to make sure that all the lye particles have completely dissolved.
Prepare to mix your soap like you normally would, but when it comes time to add the lye solution to the oils, add the liquid goat's milk first and stir it well. Then add the double-strength lye solution to the mixture and mix until it reaches trace. You may get a tiny shift of color using this method, but not too much.
Soap With Powdered Goat's MilkFor people who don't have fresh or canned goat's milk, powdered milk actually works really well. I know many people swear by fresh or canned goat's milk, But I've used the powdered goat's milk many times and it actually comes out really wonderfully. Check with the vendor of milk you're buying to find out the concentration. The powder I use is pretty concentrated. I use about 1 oz by weight of powdered milk for every 8 oz of water in my recipe. As you are measuring out your oils, separate two or three ounces of oil and mix the goat's milk into it with a whisk. Stir it well to get out the lumps. Set it aside to add at trace.
Make your lye-water solution as you normally would and then make your soap as you normally would. Add a very light trace, add in the goat's milk/oil mixture. Stir well and pour as you normally would.
So those are the three methods at incorporating goat's milk into your soap: using fresh frozen goat's milk, using canned evaporated double strength goat's milk, and then using powdered goat's milk. While using any of these methods, your color should only shift a little bit beige, a little bit ivory colored. Regardless of which method you use, and what color your soap is, your customers and family are sure to like your goat's milk soap.
