Procter & Gamble Co is being sued by parents claiming new Pampers diapers have caused severe rashes and other skin conditions on their children, court documents showed, assertions the company has called "completely false."

The action, filed by the law firm of Keller Rohrback, comes on the heels of parents' complaints that updated Pampers Swaddlers and Cruisers diapers with P&G's new Dry Max technology appear to have caused rashes and burns on their children. A number of parents have voiced concern in Internet forums such as Facebook.

"While we have great empathy for any parent dealing with diaper rash - a common and sometimes severe condition - the claims made in this lawsuit are completely false," P&G said in a statement. "We have every confidence that we will prevail in this meritless lawsuit."

According to documents, the lawsuit wants the court to require P&G to ensure that Pampers will not cause severe rashes, blisters, welts, chemical burns and other skin ailments and to regularly test the product. It also wants parents to be reimbursed for the diapers and compensated for treatment of skin ailments in their children they say were caused by the diapers.

Last week, Pampers dismissed reports that the diapers were causing skin irritations after the U.S. Consumer Product Safety Commission and Health Canada said they were investigating the products.
