AB 1901 would create a new product-safety disclosure regime for children’s diapers in California. The bill requires manufacturers of children’s diapers sold, distributed, or manufactured in the state to post, by January 1, 2028, a publicly accessible list of all intentionally added ingredients on their websites and on the product detail pages where the diapers are sold online. That disclosure must include each ingredient’s chemical or raw material name, CAS number, and specific function or purpose, and the information must be organized in order of chemical or raw material weight.
By January 1, 2029, the bill also requires the outermost package of every children’s diaper sold in California to include a website address that links to the same ingredient information, along with a package-level list of intentionally added ingredients. The bill defines “children’s diaper” broadly to include disposable briefs, protective underwear, liners, boosters, inserts, underpads, and components such as wetness indicators, absorbent linings, outer shells, adhesive tabs, dyes, and fragrance. “Intentionally added ingredients” is defined to cover chemicals intentionally added for a functional or technical effect, including certain components and breakdown products.
The bill would amend the Health and Safety Code by adding Chapter 12.7 to Division 104, placing these requirements under the authority of the Department of Toxic Substances Control. It authorizes enforcement by the department, the Attorney General, and local prosecutors, and it allows civil or administrative penalties of up to $5,000 for a first violation and $10,000 for subsequent violations. Violations may be assessed per violation or per day for continuing violations, and prevailing parties may recover attorneys’ fees and costs. Penalty revenue would go into the Toxic Substances Control Account, and the department could use that account, if appropriated by the Legislature, to implement the law.
The overall sentiment reflected in the bill’s history appears favorable, at least at the committee level, with the measure receiving a unanimous 5-0 do pass recommendation before being re-referred to Appropriations. The bill’s structure suggests a consumer-protection and transparency rationale, aimed at helping parents and caregivers know what chemicals are present in diaper products. No committee transcript is available here, so the record does not show detailed debate, but the vote indicates no recorded opposition in the committee action provided.
The main points of contention are likely to center on compliance burden, disclosure scope, and enforcement costs rather than the basic goal of transparency. Manufacturers may object to the requirement to disclose ingredient names, CAS numbers, and functions both online and on packaging, especially for products sold through multiple channels. There may also be questions about how the Department of Toxic Substances Control would fund and administer enforcement, since the bill is marked fiscal and authorizes use of the Toxic Substances Control Account only upon legislative appropriation.
AB 1901 would add a new chapter to the Health and Safety Code governing ingredient disclosure for children’s diapers and would effectively prohibit sale, distribution, or manufacture of noncompliant diapers in California. It would impose new labeling and online disclosure duties on manufacturers and sellers, create enforcement authority for state and local prosecutors, and establish administrative/civil penalties for violations. The bill would also direct penalty revenue to the Toxic Substances Control Account and allow the Department of Toxic Substances Control to adopt implementing regulations, thereby expanding the department’s role in product-safety oversight.
The available voting history suggests generally positive sentiment toward the bill, with a 5-0 committee vote to pass it and move it to Appropriations. That unanimous vote indicates broad support at the committee stage for increased transparency about diaper ingredients and chemical disclosures. Because no hearing transcript is provided, there is no direct record of floor or committee debate, but the bill’s progress suggests the concept was not controversial enough at that stage to generate recorded opposition.
Likely areas of contention include the cost and practicality of compiling and maintaining detailed ingredient disclosures, especially for products with complex supply chains or multiple retail platforms. Manufacturers may also be concerned about the requirement to list ingredients in order of weight, identify CAS numbers, and disclose functions or purposes, which could raise trade-secret, formulation, or administrative burden concerns. On the government side, the bill’s enforcement and implementation costs may be debated because it is fiscal and relies on the Toxic Substances Control Account only upon appropriation, meaning funding and staffing for enforcement could be a point of scrutiny in Appropriations.
