How to Make Diaper Rash Cream

Sunday, July 14, 2013

I have tried several different diaper rash creams and have not really found one to work perfectly for me. I have used Aveeno, Desitin, Butt Paste, Vaseline, Triple cream, and Aquaphor. None of them really did the trick. They would help a little, but not totally. After spending lots of money on them, I tried to find a "better" brand, and found them to be super expensive. So I started developing my own diaper rash cream.

After experimenting a bit, I ended up with a cream that works better than anything else I have tried. Our son is prone to eczema and is alergic to certain baby wipes, like Costco's Kirkland wipes, and to his own poop. Whenever he poops, he gets red around the rectum and I always need to put cream on. He also gets diaper rashes during really hot weather. This rash cream I developed works well for all those conditions. So I'll share it with you now, and you can make it yourself if you so choose.

The ingredients are not expensive, and once you get them, you can continue to make batches and batches of this cream, along with other types of creams you might want to make. The main ingredient is castorlatum, which is similar to petrolatum, but it is made from castor oil. It seems to be the thing that really makes this diaper cream work well. It creates a barrier to protect against wetness, which is a major cause of diaper rash.

The virgin coconut oil is very healing and conditioning. The sunflower oil is great for the skin and adds softness and spreadability. Tamanu oil is very healing to the skin. (I also use straight Tamanu oil on mosquito bites, and they are healed permanently within 20 minutes. No more itching all week long.) You may be able to get away without the ground oatmeal. I heard that oatmeal is good for the skin, but mostly after it has been cooked. The oatmeal I used was raw, and I bought it in colloidal form (superfinely ground). ROE is to prevent the oils from going rancid, which they seem to do quickly in hot weather. But you can use a liquid capsule or two of vitamin E.


Castorlatum - 3/4 cup
Coconut Oil (virgin) - 1/4 cup
Sunflower Oil - 1/8 cup
Zinc oxide - 2 Tblsp
Tamanu Oil  - 1oz
Oatmeal (ground) - 1 Tblsp
Rosemary Oeloresin Extract (ROE) - 2 drops


1. Melt coconut oil by placing a container of it in a warm/hot water bath.

2. Mix in the Zinc powder until it fully dissolves.

3. Add Sunflower oil, tamanu oil, oatmeal, and ROE

4. Place castorlatum into a mixing bowl.

5. Slowly add the oil mixture to the castorlatum, a little at a time, mixing it in with a fork.

6. Beat the mixture well until it becomes like a diaper cream texture, making sure that the coconut oil re-solidifies.

7. Place into a jar, and use liberally as needed. I usually apply it using a Q-tip.

This new concoction didn't seem to work as well as the original one I made. I was a bit surprised because the previous cream I made worked like a miracle. Baby J (now 2yo) has had reactions to this new diaper cream, getting redder on his bottom where I applied this. And it has happened consistently the few times I have used it. I would use it and then switch to Aquaphor and it would clear up. Then when I went to use this diaper rash cream again, it would flare up again.

So I don't know if it is the Seabuckthorn Seed oil that I used in lieu of the Tamanu oil or what, but I have stopped using the cream. I suppose I will make a new batch with the Tamanu oil instead. I'll let you know if that helped it.

I loved this diaper rash cream so much. I used up this batch entirely, and made a new batch today. The only thing I didn't like about the first batch was the smell. I don't know if it is the castorlatum or the ROE that caused the smell. It started off smelling OK, and then turned into a little rancid oily smell. The ROE was supposed to prevent it from going rancid, but maybe I need a new batch of ROE. But I would probably go with just Vitamin E capsules instead.

This time, I didn't use tamanu oil, I used Seabuckthorn Seed oil instead. Just cuz I had it, and didn't really have enough tamanu oil. I also didn't wait until the coconut oil fully rehardened before I placed the finished mixture into the jar. Just because I didn't feel like waiting, and I didn't want it to get too hard before I put it into the jar.

I'll keep you posted on this new concoction!
