Why are there warning labels on bubble bath products for children?

During the 1970's medical reports and complaints received from consumers by the Food Drug Administration (FDA) demonstrated that the use of children's bubble bath products was frequently associated with skin irritation and urinary tract infections; therefore, the FDA promulgated a regulation which requires that the label of children's foaming detergent bath products (bubble baths) bear the following warning statement.

"CAUTION: Use only as directed. Excessive use or prolonged exposure may cause irritation to skin and urinary tract. Discontinue use if rash, redness, or itching occurs. Consult your physician if irritation persists".

Currently marketed children's bubble bath products should be safe under conditions of intended use; however, occasionally a sensitive individual may experience an adverse reaction. The purpose of the required warning statement is to advise the user who may experience such a reaction.
