Oatmeal Cinnamon Soap

Earlier this year we made the Oatmeal & Honey Almond Soap. Once again, we are going to make soap with oatmeal. Today’s batch of soap will be similar to the Oatmeal Cinnamon Soap Recipe, but I’ve made several changes to suit the ingredients I have on hand, as well as make this batch easier to make. I used the Lye Calculator to recalculate the lye necessary for this recipe.

Collect needed items:

Castor Oil
Grapeseed Oil
Palm Kernel Oil
Hydrogenated Soybean Oil
Sunflower Oil, High Oleic
Lye (sodium hydroxide)
Gingerbread & Spice Fragrance Oil
Soap Spoon
Long Loaf Mold
Immersion Blender
Time spent:Weighing time: 8 minutes
Adding lye to water: 5 seconds, followed by 60 seconds of stirring
Heating of oils time: 2 minutes
Pouring lye solution into the fat mixture: 5 seconds
Using immersion blender to mix soap solution: 2 minutes
Mix oat flour into the soap solution: 45 seconds
Pour into mold: 30 seconds
Allow soap to rest: 24 hours
Recipe in ounces:
8 oz wt Castor Oil
12 oz wt Grapeseed Oil
10 oz wt Palm Kernel Oil
38 oz wt Hydrogenated Soybean Oil
12 oz wt Sunflower Oil

30 fluid ounces water
10.4 oz wt lye

4 oz wt finely ground oatmeal was used as a filler
1 teaspoon Ground Cinnamon as a colorant
1 fl oz Gingerbread & Spice Fragrance Oil

Grind oatmeal to a fine flour. Measure 4 ounces. Set aside.

Measure oils on your scale. Warm on the stove or in the microwave. Bring temperature to near 120 °F. Exact temperature is not critical. Add sodium hydroxide to the water. Mix well. Allow to cool to near 120 °F. Once again, exact temperature is not critical. It is a good idea to record your temperatures so refinements can be made. Since this particular batch of soap was poured into one deep mold, the temperatures do not have to be as high as when pouring the same batch size into a shallow mold.

Combine oils and lye solution. Stir until thin trace. Add finely ground oatmeal and ground cinnamon. Adding the oatmeal slowly while continuously stirring will help prevent lumping. Stir out any lumps. Upon trace add the Gingerbread & Spice Fragrance Oil. Stir well. Pour soap into molds. Allow to sit until soap is firm.

Cut into bars. Stack to allow good air circulation. Allow to cure for several days before using. Longer curing will result in a harder bar.

Notes & Comments:
Please note that some individuals can have an allergic reaction to cinnamon. Please label your soap. We think the color is gorgeous! Try it if your family doesn’t have a cinnamon allergy.

Ground cinnamon will accelerate the trace, so be prepared to see your soap turn from very fluid to mashed potatoes in 2 minutes flat! You may add the cinnamon to the soap when you add your fragrance to minimize the acceleration. Before adding make sure your molds are ready for the soap!

About Andee

Director of Happiness. I'm a thirty-something soap snob. I've grown up with handmade soaps, and I love them! I really like making lotions, soaps, and perfumes. I adore mixing scents to come up with something new. My favorite scent is either Wicked or Cotton Candy. I tend to hoard fragrances, I even have an Earl Grey Tea from the MMS catalog. I won't tell you how old it is, but it sure is good!
