Making Soap with Goat Milk: Random Information and a Recipe


This is Part Five of my series on making soap with goat milk. You can click here to read Part OnePart TwoPart Three and Part Four.

Once I started writing about making soap I just kept going and going! There was just so much I wanted to share. 

This post contains some random thoughts that didn't fit anywhere else, where to find ingredients, ideas for additions to soap, a basic recipe, and a way to get around using lye if you want to make soap without lye.

First, a disclaimer and disclosure:

Oils and Fats

You can substitute any fat for another kind of oil, but be sure to use a lye calculator so you know how much lye to use. 

Any time you change a recipe you'll need to check the amount of lye, but if you use the same recipe all the time without changing the amount or type of oils or fats, the amount of lye won't change.

Many soap makers stick to vegetarian soaps that use plant-based oils exclusively - no lard or tallow included. Consumers tend to believe that tallow produces a low-quality soap that doesn't clean well and clogs pores.

But this isn't true. Tallow makes a creamy lather, is skin-conditioning, and makes a hard bar of soap that will last significantly longer than one made with vegetable oils only.

Actually, many of today's brands of commercial soap are made with tallow. This has given tallow a reputation of being harsh, but it's the harsh chemicals and detergents in commercial soaps that are hard on our skin, not the tallow itself. 

Commercial soap manufacturers also remove the glycerin that is a natural by-product of soap making; handmade soaps contain all the natural glycerin. 

A bar of soap made with 100% tallow wouldn't clean as well as one made with a variety of oils and fats though, so it's best to make soap with more than one kind of fat. Different fats give different properties to your soap.

I have a favorite recipe that I've developed and I use it 98% of the time. 

I prefer using oils and fats that I can purchase easily or even render myself from animal fat. I use coconut oil and that is the hardest ingredient to source, although it's so popular now that it's much easier to find than it used to be when I started on the adventure of making soap. 

Lard can be purchased at the grocery store but I render it from our pigs when they are butchered. I've rendered sheep tallow from the lambs we once butchered, and friends have given me fat from their deer when they have a successful hunt.

Where to buy fats and oils for soap making

If you are buying lard at the grocery store, look in the baking aisle, probably on the bottom shelf. Coconut oil is usually in the same area, but on a higher shelf. 

Vegetable oils such as corn, sunflower, safflower and soybean are easy to find and might be in your cupboard already. 

Castor oil is sold in the health and beauty section; ask the pharmacist if you have trouble finding it. 

Other soap oils such as shea butter and palm oil are available online if you wish to use them.

A simple and frugal way to obtain beef tallow is to save the fat when cooking ground beef, keep it in the refrigerator until you have enough, then render it. 

I've done it - it works just like you'd butchered your own steer, although sometimes I've had to render it two or three times to get clean tallow. I'm now using the beef fat I rendered from our steer.

How to easily change your soap recipe

I've made soap using tea or coffee added to the goat milk, using the same total amount of liquid that the recipe calls for. 

It's possible of course to make soap with all of the liquid being tea or coffee or whatever but I simply used a combination of the two liquids that totaled the amount of liquid called for in the recipe. 

Why would I want to use coffee or tea instead of goat milk? They are natural colorants. 

Surprisingly, I've found that using cream instead of milk produces a lighter, whiter bar of soap.

Sometimes I've added cinnamon and coffee grounds as exfoliates. A bonus is that these additives also change the color of the soap. 

Paprika turns soap orange, cinnamon gives a brown color and coffee (both the liquid and the grounds) lend a dark brown color.

One of my favorite soaps contains healing herbs that I've infused in olive oil. I use chickweed, yarrow and plantain that grow wild here on Oak Hill. 

I measure the infused olive oil as usual to make the soap, in other words, if my recipe calls for 12 ounces of olive oil, I use 12 ounces of infused olive oil. The infused oil is dark green and lends a light green color to the finished soap.

A Recipe at Last!

Several of you have asked for a recipe. I started out with a recipe similar to this one, a basic three-oil soap, but with lard instead of palm oil (this would change the amount of lye, so be sure to use a lye calculator to tell you how much lye to use). 

Please don't try making your first batch of soap with a single ingredient; I've had so many people tell me they've tried olive oil or castile soap first and it was a total bust. 

Once you've mastered this three-oil soap you can try another recipe, ok?

After I made this one a time or two, I changed the recipe a bit, one oil at a time, until I was happy with the result, and that's what I've been making ever since. 

For instance, here's how to add castor oil to your soap.

For instance, castor oil lends a nice lather to your soap and is a good addition to the combination of oils you use.

If you were to add castor oil to a recipe, however, here's how you should do it. Replace part of the amount of another oil, do not just add more oils

And then use a lye calculator so you'll know how much lye to add to this "new" recipe. Remember that you've not only added an ounce or two of castor oil, but you've also subtracted the same number of ounces of another oil.

A little castor oil goes a long way, I started by substituting with just one ounce to my recipe.

Here's how to use a lye calculator.

Melt and Pour Soap

If you want to try soap making but just don't want to worry about the danger of using lye, you can buy melt-and-pour soap base. My granddaughter and I had a fun afternoon making melt and pour soap together.

  1. Love the infused Olive Oil idea :)
    I also never thought of rendering fat for soap making. Too bad, I didn't think of it when we had our steer processed.
    Great Series!!

    We had 2 hogs processed before I thought to save that beautiful fat, Sandra, but now we know...

  3. Thank you Kathi. I especially appreciated that you pointed out where in the grocery store to look for the oils. I have left a grocery store many times without ingredients because I couldn't find them!

    You're welcome, Jennifer. Someone finally told me where to look for the castor oil, and I've been telling others ever since.

  5. Making soap is on my to do list. Can't wait to try it. Thanks for sharing at the Homestead Blog Hop. Hope to see you again this week. :)

  6. Love the idea of the infused oil in the soap! Thank you for continuing to share this series on the Art of Home-Making Mondays! :)

  7. Thank so much for sharing! Wonderful thoughts and guides for soap making, as always!!
    Hope to see you again tomorrow on Wednesday's Homestead Blog Hop.
    Pinned! :-)

    Thank you very much for the pin, Kelly! Have a blessed week.

  9. They look to pretty to use! Thanks for sharing it with us over at Country Fair Blog Party!

    Great site! Easy to understand instructions and love your photos at top of your website. Refreshing and calming. The soap bar photos are lovely too.

  11. The 3-oil soap recipe doesn't mention the use of goat's milk. How do you know how much of that to use? I'm a beginner, and want to make sure I understand what I'm doing before I start!

    Thanks for this series, I've really learned a lot and look forward to trying it!

    1. Excellent question, Karon! Using a lye calculator will help you. You'd put in the amount of each oil and click "calculate." It will figure out how much lye and liquid you should use. Goat milk is interchangeable with the water that is most often used in soapmaking, so you'd use the amount of liquid the calculator figured out for you. Goat milk would add some extra fat to your recipe though, which makes a more luxurious soap. (Hmm, I think I need to write a post about this.)
