An international coalition of health and environmental groups contested that two chemicals considered harmful to babies remain in Johnson & Johnson’s baby shampoo sold in the U.S. and some other countries, even though the company already makes versions without them. Now the coalition is urging consumers to boycott Johnson & Johnson baby products until the company agrees to remove the chemicals from its baby products sold around the world, including in China and the U.K.

The Campaign for Safe Cosmetics has unsuccessfully been urging the world’s largest health care company for two years and a half to remove the trace amounts of potentially cancer-causing chemicals — dioxane and a substance called quaternium-15 that releases formaldehyde — from Johnson’s Baby Shampoo.

However, Johnson & Johnson have heard been saying that it is reducing or gradually phasing out the chemicals.
