Carcinogenic (cancer causing) materials have been discovered in baby shampoo products made and distributed by Johnson & Johnson Company. These chemicals include Quarternium-15 which prevents products from spoiling and contamination by releasing formaldehyde to kill bacteria.

There is an argument as to how much risk these chemicals pose to users of these products. Johnson and Johnson claims that using a single dose of any of their products cannot cause a bad reaction in children. But the question remains as to how much risk repeatedly using these products can pose.

Johnson & Johnson has only taken corrective steps after threatened boycotts from the Campaign for Safe Cosmetics and proddings from thousands of consumers.
