After looking at previous skin studies that revealed how soap can deliver compounds through the skin, they evaluated infant wipes using mice, again. Once the animals were exposed to baby wipes and then dust and food allergens for 40 minutes during a two-week period, they were given an egg or a peanut. The rodents had severe and immediate allergic reactions on their skin and intestines.
The scientists realized the combination of the mutations and soapiness affect the skin’s ability to fight off dust and food allergens. “This is a recipe for developing food allergy,” Cook-Mills said in a statement. “It's a major advance in our understanding of how food allergy starts early in life.”
