Start by creating a double broiler with a glass bowl. You can do this by putting approximately 2 cups of water into a saucepan and letting it come to a boil on the stove.
While the water is coming to a boil, measure out your ingredients. The shea butter typically comes in blocks so it will need to be cut to fit (doesn’t have to be perfect) a 1/4 cup measure. You can purchase the exact shea butter I used here.
Once the water is boiling, use a glass bowl (or anything that can tolerate heat), setting it on top of the saucepan.
Add the coconut oil and shea butter to the glass bowl that is on the double boiler. Using a wooden spoon or rubber spatula, mix the two together as they start to melt. Be sure to keep your eye on this because it melts fast and needs to be stirred often.
When the coconut oil and shea butter have melted, add in the 1/4 Tsp vitamin E oil and lavender essential oil if you choose to use that. Mix.
Take the glass bowl off the heat, setting it on a stable surface. Slowly whisk in the arrowroot powder. This may take a few minutes to ensure there are no clumps.
The mixture should be totally smooth at this point, quickly pour it into whatever container you will be using for this diaper rash cream and set it in the fridge to set. You can also leave this at room temperature on the counter to set however it will take much longer.
My homemade diaper rash cream takes about 2-3 hours to set in the fridge. Once set, pull it out and let it come to room temperature. If the cream is smooth and silky, it's ready to use!
Notes
If you are dealing with a yeast rash, I highly recommend using this product.
Store this in an airtight container and use it as needed. When using more than once during a single diaper change, be sure to wash your hands before dipping back into the jar in order to not create cross-contamination between the rash and the cream.
I use this on my cloth diapers and have had no issues.
