So you may be wondering why I use a synthetic substance, zinc oxide, in my products if I’m trying to be all natural. You may not even know exactly what zinc oxide is. I definitely didn’t until doing some extensive research as I started creating baby products.
As soon as I started down this crunchy path creating my own beauty and household products, I decided that I wanted to be as knowledgeable as possible on every substance I put in or on my body. I stay away from processed foods, synthetically produced substances and toxic chemicals. The very core of my values related to my product line is to keep it natural. That’s why I want to explain what zinc oxide is and why I’m using it in the diaper rash cream.
What is Zinc Oxide?
Zinc oxide is a fine white powder that is insoluble in water. That simply means that if you dump a little zinc oxide into a cup of hot water and stir it around, you’ll just end up with powder and water. Zinc oxide can occur naturally as the mineral zincite but most zinc oxide is synthetically produced. (see wikipedia) You’ll find zinc oxide in a lot of products as an additive, and in the beauty world you will see it in diaper rash cream and in sunscreen.
Why Zinc Oxide Works Like Magic in Diaper Rash Creams
When you mix zinc oxide with hot emollients, butters, and oils the end result is a thick white cream. While the cream is still hot, you can see the powdery zinc oxide as a separate substance but as it cools the cream becomes a normal consistency and the powder dissolves.
Rub the zinc oxide cream on your skin and water droplets will sit on top of the cream. Wash your zinc oxide hands in warm water and you’ll still have beading water. The zinc oxide repels the water and keeps it away from your skin. This is exactly what it does on your baby’s body as well. Wet diapers won’t cause diaper rash because your baby has a layer of zinc oxide cream on that repels the wetness. It’s the best substance to use in diaper rash creams because it works so well at repelling moisture.
Zinc Oxide Percentages in Other Diaper Rash Creams
Zinc oxide can be found in most “natural” diaper rash creams as well as most mainstream store bought creams. It is the active substance in all these creams which means it’s what makes the cream work. Here are a few common creams that contain zinc oxide and the percentage that they contain:
Booty Goo – 25%
Bourdreaux’s Butt Paste – 16%
Triple Paste -12.8%
Burt’s Bees Baby Bee Diaper Ointment (Owned by Clorox) – ???% This is the only diaper rash cream without the percentage of zinc oxide listed on the label. Zinc oxide is the second ingredient on the label. (Ingredients are listed in order by how much of each ingredient is in the recipe so the first ingredients are the largest portions.)
Zinc Oxide and Cloth Diapers
The downside is that it’s tough to get the cream off hands, bodies and clothes because zinc oxide repels water. There are many zinc oxide rash creams that say they are diaper safe. Apparently fish oils are the really pesky ingredient in diaper rash creams that just won’t wash out such as cod liver oil.
If you are using cloth diapers, I would definitely suggest using a liner with my diaper rash cream. If you are using natural fiber diapers, the zinc oxide should wash out fine but a liner is a good idea. With synthetic cloth diapers such as pocket diapers, you need to stay away from zinc oxide creams so my baby balm would be a better choice as a diaper rash cream.

What are nanoparticles and are they bad?
Nano-particles in zinc oxide have become controversial in recent years. Basically, in non-scientific terms, a nanoparticle is a super tiny version of a substance. Initially, products with zinc oxide touted nanoparticles as a feature because zinc oxide with nano-particles were absorbed into your skin so the nanoparticles wouldn’t leave a white residue on your skin. It seemed like a good feature until further research was done. The problem with nanoparticles is that the structure of a substance can change.
It’s a controversial subject, and I choose to simply use the non nano-particle zinc oxide as a safety precaution. Many companies have changed their sunscreens and diaper rash creams to non-nanoparticles as well.
