In 2011, Women's Voices for the Earth posted a list of home cleaning and laundry products that contained questionable chemicals. One of those products was Tide Free & Gentle. Another environmental group, As We Sow, filed a lawsuit in California requiring that Tide reformulate to reduce or remove 1,4 dioxane, a chemical that cause cancer or birth defects. The chemical was found in small traces in Tide due to the way the product is manufactured. 1,4 dioxane is used to clean equipment in the manufacturing facilities.
Last week, Tide agreed to change their manufacturing process to remove the chemical by September 2013. While the agreement is only effective in California, a spokesperson for Procter & Gamble says that the new product will be distributed nationwide.
