The Consumer Product Safety Commission says it is looking into reports of severe rashes caused by new types of pampers diapers.

The investigation started this week after complaints of babies and toddlers suffering severe and persistent diaper rashes and blisters.

In March, Procter and Gamble launched new versions of its Swaddlers and Cruisers Diapers in the US.

In a statement, Procter and Gamble says it has received less than two complaints about diaper rash for every one million diapers sold, which is average for its business and does not deviate from the number of calls it received prior to dry max.

The Consumer Product Safety Commission encourages parents to report any problems to the agency by calling 800-638-2772.
