California Bill Targets Diaper Ingredient Transparency

A new legislative proposal in California seeks to increase transparency in the diaper industry by requiring manufacturers to disclose all intentionally added ingredients. Current laws allow companies to conceal chemicals considered not to be significant health risks, but Assembly Bill 1901 aims to change this.

Disclosure Requirements

If enacted, the bill would mandate manufacturers to publicly reveal every added ingredient in diapers, including the specific role of each ingredient, starting January 1, 2028, for diapers manufactured, sold, or distributed in California. By the following year, this information must appear on product packaging.

Assemblymember Marc Berman, who authored the bill, emphasized the importance of parents making informed choices for their children’s health. The bill has gained strong support, passing the California Assembly 68-1 and advancing through Senate committees with minimal opposition.

Reason Behind the Legislation

“As a new dad, I have a new appreciation for how important it is for parents to make informed decisions when it comes to the health and wellness of their children,” said Marc Berman.

The push for this bill stems from concerns over chemical exposure from diapers. Research indicates that children in the U.S. typically use around 7,000 disposable diapers. Concerns have been raised about toxic substances like phthalates and PFAS present in these products, which are not always disclosed.

AB 1901’s requirements extend beyond similar legislation in New York, demanding manufacturers not only publish ingredient details online but also print them on packaging. Violations could result in penalties from $5,000 for the first violation to $10,000 for subsequent ones.

Advocates and Opponents

Organizations such as the Environmental Working Group (EWG) and Consumer Reports support the bill. They highlight issues with manufacturers using vague terms like ‘fragrance’ that conceal numerous chemicals with potential health effects. Several consumer advocacy groups and individuals have endorsed the bill.

Conversely, business groups including the California Chamber of Commerce oppose the bill. The Center for Baby and Adult Hygiene Products (BAHP) argues that diapers adhere to strict safety standards, and its member companies already exceed regulatory demands.

“Diapers are designed and manufactured to meet strict safety standards, and decades of real-world use support their safety for infants and children,” a spokesperson for BAHP stated.

Bill Progress

Initially introduced in March, the bill passed the Assembly in May with substantial support. It has also cleared Senate committees and awaits a full Senate vote. Implementation costs are projected to start at $535,000 in the fiscal year 2027-2028, increasing but eventually leveling out in subsequent years.
