Pampers Fresh Clean wet wipes provide an even more thorough clean (compared to the previous product) thanks to the softer and stronger wet wipe, but still with the refreshing scent that you and your baby love. The enzymes from urine and stool change the pH of baby's delicate skin and increase the risk of irritation and nappy rash. All Pampers wet wipes contain a unique formula that protects the natural pH of baby's skin better than cotton and water. Pampers Fresh Clean wet wipes are dermatologically tested and endorsed by dermatologists from the Skin Health Alliance. Because Pampers Fresh Clean wet wipes are designed for baby's sensitive skin, they contain no alcohol or dyes.
