In the aftermath of a report revealing that popular Johnson & Johnson baby care products contain carcinogens, a coalition of environmental, health and consumer groups are demanding the company remove the toxins from their product line.

The chemicals in question are 1,4-dioxane and preservatives that release formaldehyde. A letter was sent to Johnson & Johnson by the Campaign for Safe Cosmetics and was signed by nearly 50 groups representing about 1.7 million members, from the Environmental Working Group and Friends of the Earth to the American Nurses Association and Physicians for Social Responsibility, according to an Associated Press story.
