Oatmeal, Milk and Honey is a classic soap to make. It’s one of the first soaps that I made when I first started to make soap. This method of milk soapmaking is a bit different than the other method where we used frozen milk in the lye solution. This method uses equal amounts of lye and water for the solution and then another equal amount of milk is added to the oils. Some people find this method easier when soaping with milk. You can use this method for any type of milk including goat, cow, hemp, coconut, soy, oat…etc.
In standard milk soapmaking you typically freeze your milk into ice cubes and use them for your lye solution. This helps keep the temps of the lye solution down. Milk soap turns orange because of the lye reacting to the sugars in the milk.
In the “Milk in Oil” method…you make a lye solution with equal parts lye and water. Then you add another equal part milk to the oils before you add the lye solution. This prevents the lye reacting with the sugars too much. You also don’t have to go through the hassle of freezing your milk. For some people it is just easier to do.
I like to run my oatmeal through a mini food chopper or a coffee grinder to grind it down some. The larger the pieces…the scratchier the soap. I prefer instant as it is softer in the soap but you can use any kind. I get fresh goat’s milk from another local soaper, Donna.

The first step is to make our lye solution. I mention above to make the lye solution with equal parts of lye and water. I always add a splash more because sometimes the mixture can fall out of solution if there is not enough water. Usually equal parts is the most concentrated you should go.
Measure out the water and the lye. Add the lye to the water and mix in a well ventilated area.
So now we have the oils, milk, honey, oats and fragrance. Give this a good stickblend to make sure everything is well mixed.
Take a look at the lye solution. You might see some floating white filmy stuff. Give it a mix. This is just because it is such a concentrated solution and the lye is reacting to the carbon in the air and forming sodium carbonate. Lye (undissolved crust) stuck to the bottom of your container is bad…white floaties are not.
Okay…so this soap likes to heat up. Honey and (the sugar in) milk like to heat up when in the mold. I prefer my soap gelled so I really have to keep an eye on it. I cover, but I check on it every ten minutes or so. If you don’t want your soap to gel or are afraid of overheating…you can put your soap somewhere cool like in the fridge or freezer…or even outside if its cold outside.
There is definitely a difference in color between gelled (darker) and ungelled (lighter) soap.
You can soap milk two different ways – full milk in lye solution or milk in oils as above.
Oatmeal – rate of 1 tablespoon PPO
Honey – rate of 1 tablespoon PPO
Happy (Goat’s) Milk Soaping!
