What’s Really In Your Baby’s Diaper?
As a parent, your biggest concern is your child’s health. If your child is currently in diapers, the thought of “What’s really in my baby’s diaper?” has crossed your mind recently. The quest for researching ingredients can be overwhelming. But look no further, we have all the information summarized here for you.
First, we must break down the layers of your baby’s diaper:
Top sheet (or Inner Layer): The layer that sits directly on your baby’s skin
Absorbent core: The layer that absorbs the fluids
Waterproof outer shell: The outer materials of the actual diaper

The two ingredients that are commonly present in most diapers are polypropylene and polyethylene. Followed by sodium polyacrylate, wood pulp, polyurethane, and polyester. Some brands also use dyes and fragrances in their diapers. What? No cotton? Nope, no cotton at all.
As we mentioned earlier, the top sheet of a diaper is in direct contact with your baby’s sensitive areas. This layer consists of a plastic film that covers the absorbent core; it is often made of polypropylene and polyethylene, the same materials used to make plastic products like plastic wrap, bottles, bags, and containers.
Since the 1980’s, the absorbent core in most diapers are made of Super Absorbent Polymer (SAP), or sodium polyacrylate. SAP, which is made of small absorbent crystals, is found in the layers of the diaper core. When in contact with moisture, these crystals expand in order to absorb large amounts of liquid waste. SAP is derived from petroleum, although diaper companies are currently researching a plant-based alternative. The super-absorbency sounds great until your baby moves, forcing waste out.
Waterproof Outer Shell
The outer shell of a diaper is also made of polypropylene and polyethylene. Graphics on the diaper are printed with dyes and pigments. In addition to these two chemicals, polyurethane is also used in the elastic waistband and synthetic rubber for the fastener.
The Ideal Diaper
Because the typical disposable diaper is made of entirely plastic, it is far from biodegradable. Purified Cotton™ would be the obvious choice for the ideal diaper because it’s the purest natural fiber on the planet, naturally hydrophilic (but can be made hydrophobic), and naturally biodegradable. Some diapers companies call themselves “green”, but only use cotton on the back sheet because it gives the feel of cotton. However, cotton on the back sheet is pretty much useless to the health of the baby. It is the components of the top sheet that matter most. That’s where Purified Cotton™ comes in.
