When you have an abundance of goat’s milk and you use it for drinking, cheese, ice cream and every recipe you can find that has milk it’s natural to want to find other ways to use it. With heavy milking Toggenburgs, Alpines, Saanens and recorded grades there was plenty of milk and soaps were a natural extension to make and sell.
Goat’s milk soaps have been credited with clearing skin conditions and milk soaps as a rule are gentler than those with harsh chemicals. Making goats milk soaps is not difficult but it is exacting.
You will need to gather supplies. These include a large stainless steel kettle for mixing the soap. Make sure this is stainless steel rather than aluminum or other materials as it not only has to stand the heat but the caustic nature of the lye reacting to make soap. A stainless steel spoon helps as well as a stick blender used just for your soap making. A wide variety of molds can be used including plastic containers providing they can handle heat. A couple of candy or meat thermometers are needed also as you’ll need to watch temperatures.
Highly recommended are plastic safety goggles and long sleeves with gloves. Keep pets and small children out of the room or confined when mixing soap for their safety and yours.
You can follow an existing recipe or as you gain experience create your own. An excellent source for soapmakers is http://www.thesage.com/calcs/l as you can plug in your type of lye, liquid, what kind of fats and it calculates how much lye to use for you.
For example to use 12 ounces of corn oil and 36 ounces soybean oil (vegetable oil) it calls for 12-18 ounces of milk and, for the medium range, 6.18 to 5.98 ounces of lye, with the lower range making a softer soap.
Measure the oils into a pan and place on low on the stove, with a thermometer attached to the pan to watch the temperature. While that is heating work on the other half of the equation.
Measure the milk into the pot and add the lye to it. Always add it this way and with milk soaps watch carefully your thermometer. I found better success by placing the pan I’m working in in a sink of cold water. As you add the lye you will find the milk heats up considerablythe cold water outside the pan helps disperse this heat somewhat. By watching the temperature try to keep it less than 140 degreesas it starts to heat up slow down pouring and keep gently stirring.
The reason for this caution is to keep the milk from curdling, a problem some soapmakers have found. By watching the heat and doing it this way I never had a problem with this issue. Once all the lye is added you’ll need to carefully balance things to bring the lye mixture and the oils to the same temperature. I used 100 degrees as my temperature. The important thing is that both are the same temperature.
Once the same temperature is reached add the oils to the lye mixture, stirring constantly. Some soapmakers use a stick blender once the oils are added while others prefer to stir by hand. Be careful not to splash it or allow pets or children to stir it. As you are stirring you are looking for “tracing” which can take more than 15 minutes but with a blender can take less. Look carefully for this which will leave a drop for several seconds or leave a pattern where you have stirred for several seconds. Once this is seen quickly pour into your prepared molds as the soap is soft but can set quickly.
Once in the molds lightly cover and cover with a blanket to regulate temperature. If the soap cools too quickly it can spoil a batch. Carefully check the soap daily to see when it is set soft but firm. If you are using a mold that requires cutting you’ll want to turn it out and cut while it’s firm but not hardened. Once your soap is cut place on a rack out of reach of pets and children to cure or harden.
As you gain experience you can add oatmeal and other things to your soaps after the oils but before tracing begins. Some even add shredded rose petals! The 48 ounce weight can make a dozen cut bars but if you pretty up’ the edges don’t throw away the peelings and pieces. You can make laundry soap and even soft soap also.
Don’t underestimate the danger of lye but don’t be afraid of it either. Treat it with respect and use it carefully. Always add the lye to liquid, not the other way around.
Soap making is a way to use some milk, although not large amounts, but is also one more thing you can produce at home. Milk soaps are not difficult to make.
