Superabsorbers |
| If you've taken a diaper off a baby sometime in the past decade, you were probably surprised--not at how messy it is, but at how heavy it is. Today's disposable diapers can hold pounds of pee and still feel quite dry, which may be why fewer than 5 percent of American babies use cloth diapers.
This astonishing absorbency comes from a family of hydrophilic ("water-loving") polymers called polyacrylates. Perhaps the simplest of these is sodium (salt) polyacrylate, which can hold 800 times its weight in distilled water. Of course, there's more to urine than water. Dissolved salts and ions reduce the absorbency by more than a factor of 10. -- Madhusree Mukerjee |

| MOST MATERIALS used in a disposable diaper are synthetic. Polypropylene, used in winter athletic underwear, makes up the inner layer; it is soft and stays dry, drawing fluid away from the skin. At the core is the polyacrylate super absorbent powder, combined with fluffy cellulose. A layer of fiber (cellulose or synthetic) fights gravity by distributing fluid over the entire surface of the powder instead of letting it pool in one spot. The outermost layer is mostly microporous polyethylene; it keeps in fluid but lets out vapor. Adhesives hold it all together: elasticized hydrophobic polypropylene cuffs around the thighs contain leaks; Velcro or sticky tabs hold the diaper on the baby. | LARGE DISPOSABLE DIAPER can hold half a gallon of water. Super absorbents are the secret. |
 | Sodium Polyacrylate has sodium (salt) carboxylate groups hanging off the main chain. In contact with water the sodium detaches, leaving only carboxyl ions. Being negatively charged, these ions repel one another so that the polymer unwinds and absorbs water, which is attracted to the sodium atoms. The polymer also has weak cross-links, which effectively leads to a three-dimensional structure. In addition, it has molecular weights of more than a million; it cannot dissolve but instead solidifies into a gel. |

Super Absorbent Core found in today's diapers is made from salt, like table salt and does not cause rash, it is biodegradable and allows for the industry as a whole to use less wood pulp and other fillers saving both our landfills and our nation's trees. Super Absorbent Core is environmentally sound and safe for baby. Super Absorbent Core is in the form of small granules inside the lining of your baby's diapers, it works to pull rash causing agents such as urine, ammonia and other fluids away from baby's skin. Super Absorbent Core allows the diaper to be form fitting, not bulky between baby's legs from to much wood pulp and fiber fill which later turns into a sodden mushy diaper when wet. Two most common causes for rash
Irritant rash. This is most conspicuous on the exposed areas, such as the round part of the buttocks. It tends to spare skin folds and creases. It's generally the result of contact with stool enzymes or irritants such as harsh soaps, baby wipes, detergents, or topical medicines. One element of diapering that continues to escape 'change' is diaper rash. The first signs of diaper rash are small, red bumps on the lower abdomen, buttocks, genitals or thighs. Today's disposable diapers contain super-absorbent materials, which help keep babies drier, but there are other factors that can still cause diaper rash; such as teething, a change in diet, a cold or other illness, or antibiotics. While your baby can have a reaction to disposable diapers, it's highly unlikely. Most studies have shown that diapers are usually not the cause of a rash. All of the raw materials used in Ultra Baby diapers have been thoroughly tested, are safety-approved to ensure trouble-free use, and have no added perfumes or dyes. All diaper manufacturers currently use similar materials and none would use any products not considered safe for a baby. However, just as adults can be allergic to certain foods or medications, some children may not be able to wear some of the materials found within disposable diapers. Pediatricians agree that the best way to keep your baby from developing diaper rash and other infections is to change the diaper frequently and clean his/her skin thoroughly after each and every diaper change. Still, if your baby's skin does get irritated, change his/her diaper even more often, lessening the time his/her tender skin has to be wet.
