California Bill Targets Toxic Chemicals in Disposable Diapers

California has introduced a bill aimed at making diaper manufacturers disclose all intentionally added chemicals in their products. Currently, business confidentiality shields companies from reporting on chemicals other than those posing a significant health risk. Assembly Bill 1901 requires manufacturers to publicly disclose all added ingredients and the specific reason for each by January 1, 2028, for diapers sold, distributed, or manufactured in California.

Companies would then need to print this information on all product packaging. The bill has received support from consumer safety organizations, including Consumer Reports and the Environmental Working Group, but faces opposition from the California Chamber of Commerce, the California Manufacturers & Technology Association, and the Center for Baby and Adult Hygiene Products, representing diaper manufacturers.

Diapers are expected to be used by an estimated 20 million women across the U.S. and can contain toxic substances like phthalates and PFAS. AB 1901 would set penalties of up to $5,000 for first violations and $10,000 for subsequent violations, with penalties accruing daily for continuing violations. The bill has already passed several California committees and is expected to reach the state Senate soon.
