Diaper Chemicals Exposed: California Bill Aims for Transparency
16 Aug
Summary
- California bill mandates disclosure of toxic chemicals in disposable diapers.
- Diapers contain substances like phthalates, lead, and PFAS, posing risks.
- Legislation requires ingredient lists on webpages by 2028 and packaging by 2029.

A new California bill is progressing to mandate the disclosure of toxic chemicals present in disposable diapers. These products can contain a range of hazardous substances including phthalates, lead, PFAS, and volatile organic compounds (VOCs), which are concerning given their prolonged contact with infants' delicate skin. The legislation, having passed the California assembly with a vote of 68-1, is now headed to the state senate.
By January 1, 2028, manufacturers will be required to list all intentionally added ingredients and their functions on a publicly accessible webpage. This will be followed by similar disclosures on product packaging by January 1, 2029. Public health advocates champion this bill, asserting that such transparency will exert significant market pressure on diaper producers to reduce or eliminate toxic components and encourage the growth of nontoxic brands.
