Diaper Dangers: California Mandates Ingredient Disclosure

The California State Senate has approved a bill mandating that disposable diaper manufacturers disclose all ingredients and their intended uses. This legislation is poised to be signed into law by Governor Gavin Newsom. Consumers will be able to access this detailed ingredient information online by the end of 2028, with packaging labels to follow by January 2029.

Actor Hilary Swank, alongside the Environmental Working Group, actively lobbied for this bill, citing concerns over chemicals found in diapers that have been linked to health problems such as hormone disruption and skin reactions. Similar disclosure laws have already been enacted in New York and Illinois, with mandates effective in late 2025 and January 2027, respectively.

Studies indicate that diapers can release volatile organic compounds (VOCs), including those linked to cancer, and may contain chemicals like quaternary ammonium compounds (QACs) and phthalates. Phthalates, in particular, have been associated with reproductive issues and premature births. Despite industry assurances of product safety, advocacy groups push for greater transparency to protect infants and children.

Experts recommend parents opt for plain, undyed diapers without wetness indicators or fragrances to minimize exposure to potentially harmful substances. The EWG offers resources to help consumers identify safer diaper choices, emphasizing informed decision-making for baby products.
