What is the absorbent core of a diaper?
Absorbent Core - this layer absorbs fluids, but when your baby repositions, fluid can be squeezed out of the core and back onto baby's skin. This liquid can be potentially contaminated by the core materials and is no longer just baby waste. To enhance absorbency, all of the diapers we tested includes a matrix of fluff material and chemical crystals, known as Super Absorbent Polymer (SAP), to soak up and trap fluid (more on this below). The role of the fluff, usually made from wood pulp and may also include wheat/corn-based materials, is to distribute the fluid across the diaper surface, while the SAP is intended to absorb and lock liquids in the core and away from the baby. The bulk of the diaper is composed of the core materials. We consider this the 2nd most important element to understand.

Why do diapers have fragrance?
Perfume fragrances are sometimes used in disposable diapers, presumably to mask poop's distinctive stench. However, an infant's rapidly evolving organ systems are both immature and exquisitely sensitive to chemical insults. The scents found in many diapers are strong and chemical-laden, harboring unnecessary irritants with the potential to cause health issues like diaper rash and respiratory symptoms. Equally concerning, manufacturers are not required to disclose the chemicals used in fragrances as the FDA allows them to consider their fragrances "trade secrets." The Campaign for Safe Cosmetics notes that "in a 2010 study of fragranced products by the Environmental Impact Assessment Review of fragranced products titled Fragranced consumer products: Chemicals emitted, ingredients unlisted, it was found that "each product emitted volatile organic compounds that have been identified as toxic or hazardous under federal law", yet, "fragrance remains unregulated.
