There was recently a study done to see if laundry detergents and soap were a big cause of people having allergic reactions affecting their skin.  The study turned up that less then 1% of the cases, people had allergic reactions from detergents and soap.  And some of the 1% of results was people that had skin irritations, but not an allergic rash to the skin. People are quick to blame these items when they get a rash they often try to switch products over and over to get the rash to disappear. Before rushing to conclusions that it is your products, visit a doctor and have your skin rash examined.
