Oatmeal soap recipe

Making soap at home is a fun and creative hobby. To create something unique, I decided to formulate a handmade soap that was gentle on the skin, and with a slightly exfoliating effect. The result was to formulate a delicate oatmeal soap recipe with the cold process.

If you are a newbie to soap making, you have to know that cold method requires the use of caustic soda to guarantee the production of soap. If you want to start creating your soaps in a conscious way, learning why some ingredients are chosen and how to use them in practice, I suggest you take a look at my last course “Soap making 101” on how to prepare soaps with the cold method.

I decided to make an oatmeal scrub soap recipe because I really liked my last DIY coffee scrub soap. You can read the recipe here if you are interested. Adding an exfoliant helps cell renewal by eliminating, with mechanical action, dead cells. This time, however, I chose a gentler exfoliant for my hands. Recently, I noticed that my hands were much more sensitive and dry. The choice of this exfoliant and the oils that I will list shortly is, therefore, not accidental but the result of targeted research to help my hands.

Oatmeal scrub soap recipe | Procedure

To make the homemade oatmeal soap we will have to:

  1. Wear gloves, protecting mask, and goggles!!!! Safety first!
  2. Weigh oils and butter carefully and dissolve them in a bain-marie.
  3. Pour distilled water (50% water and 50% ice) in a glass
  4. Weigh the caustic soda in a second glass
  5. Pour the caustic soda slowly into the water and stir with the glass bar. (NEVER THE OTHER WAY AROUND!!! ALWAYS POUR THE LYE INTO THE WATER!!!)

When the temperature of the oils and caustic soda solution is around 45°C (113°F)

  • Pour the caustic soda solution into the container with oils.
  • Mix the two parts with the immersion blender, until the trace is obtained.

For this soap, I used titanium dioxide to color it white and give it a delicate character even to the eye. To do this, I dispersed half a teaspoon of titanium dioxide in a spoon of olive oil. I mixed well and poured it all into the soap. Helping myself with a silicone spatula, I mixed the color and after a few minutes the soap mass took on a perfect white color. At this point, I added the oats and continued to stir. All that remained was to pour it into the molds and let it cured, for more than 2 weeks. 


TIPS: To prepare the caustic soda solution, I prefer to use 50% of water and 50% of the remaining water as ice. Being a very energetic reaction, this trick allows me to control the temperature and prevent it from rising rapidly to 80°C.
