I have done it a few times. It's fun and always feels great. Here is the recipe I use the most often. Good luck and enjoy.
You will need the following raw materials for this oatmeal soap:
1. 4 cups of water
2. 16 ounces of essential oils; it would be best to mix coconut and olive oils. However make sure that the coconut oil will just form 25% of the oil solution.
3. 12 ounces of lye powder
4. A quarter cup of honey
5. 1 cup of ground oatmeal
First, you have to dissolve lye by mixing it slowly with water. Be very careful though because this solution will get too hot it would be best to mix it in a heat proof bowl. After thorough mixing, let it sit and allow the solution to cool.
The next step involves cooking the essential oils (coconut and olive) at 100 degrees. Set it aside after wards and wait for the oil; to cool down a bit.
If the oil mixture is not so hot already, slowly pour the lye solution. Mix continuously until the soap mixture achieves its tracing point. This means the liquid is thicker just like your favorite pudding.
Then add honey and the ground oatmeal while mixing to evenly distribute the additional ingredients. Pour the soap mixture into prepared molders and leave for 24 hours. You can now remove the soap from the molder. Cure it for a month.
