Corn is used in many brands of modern disposable diapers.
Many modern disposable diapers use corn, often in the form of cornstarch derived polymers, to make the diapers more absorbent and eco friendly.
The cornstarch is used to create superabsorbent polymers, which lock away moisture and some disposable diapers use corn based materials for the top or soft layer and the waterproof outer ell of the diaper.
Cornstarch is used to develop and make the superabsorbent polymers also called SAP that absorb and trap the liquid or pee, which keeps the skin dry.
The SAP technology in diapers was originally inspired by research using cornstarch and some "green" diaper companies also use plant based bioplastics, which can also be derived from corn, for the waterproof outer layer of the disposable diapers.
Corn also can't grow in the wild because corn is a human made crop, which depends on human intervention for propagation.
Ancient people also selectively bred the wild grass, teosinte, over thousands of years to create the corn with larger and softer kernels and a structure in which the kernels cling tightly to the cob.
This means that the corn kernels have to be manually removed from the cob and then planted to grow, and without the human assistance, the corn would not survive or grow and produce.
Corn is man made and does not exist naturally.
Corn is a man made crop and was domesticated from the wild grass called teosinte through thousands of years of selective breeding by indigenous people in Mexico.
Today's corn does not exist wildly in the wild and corn relies on human cultivation to survive.
Teosinte which is a grass is the wild ancestor of corn.
Ancient farmers around 9,000 years ago began to cultivate the teosinte.
The teosinte ears were also small, with only a few kernels far apart, unlike the corn we know and eat today.
And over many generations, farmers also bred teosinte plants with desirable traits, like larger ears with more kernels.
The process of the artificial selection also transformed the corn plant into a more useful and productive food source.
And modern corn is also a product of the long process of domestication and is a crop which cannot survive on it's own in the wild.
