1,4-dioxane is a hidden carcinogen lurking in everyday products. It can be found in up to 46% of personal care products, including baby products, shampoo, body wash, and lotions. It is also found in many laundry detergents. 1,4-dioxane is not intentionally added to products and it does not enhance the effectiveness of a product, but rather it occurs as an unwanted byproduct. It results from a process called ethoxylation, which is used to reduce the risk of skin irritation caused by harsh petroleum-based ingredients. Manufacturers can remove dioxane from products simply and cheaply. The FDA recommends that manufactures remove the chemical; unfortunately many companies opt not to take that extra step.

Exposure to 1,4-dioxane occurs through inhalation, or breathing vapors, swallowing liquid or water contaminated with 1,4-dioxane, and through skin absorption. The International Agency for Research on Cancer (IARC) has determined that 1,4-dioxane is “possibly carcinogenic to humans.” The U.S. Department of Health and Human Services (HHS) considers 1,4-dioxane as “reasonably anticipated to be a human carcinogen.” The EPA has established that 1,4-dioxane is “likely to be carcinogenic to humans.” Exposure to this chemical is linked to tumors of the liver,
gallbladder, nasal cavity, lung, skin, and breast.
