Before the legislation was passed in 2024, the disclosure of diaper ingredients was not required in any state in the U.S., meaning companies did not have to inform parents and caregivers about the substances babies were exposed to daily through their diapers.
As of December 2025, manufacturers selling diapers in the state must list all ingredients in the product on the package, including fragrances, dyes, adhesives, and bleaching agents, which are commonly used in the production of disposable diapers.
The law doesn’t currently specify how manufacturers must list their ingredients on diaper packaging, but it states that an “intentionally added substance” must be listed in order of predominance. This could mean that diaper makers can simply list “fragrance” as a catch-all term for the more than 100 different compounds that fall under that umbrella, which may not be helpful for a parent trying to avoid specific chemicals.
Rosenthal says she’ll make changes to the law as needed. “I will be monitoring the implementation of this law and if more specificity is needed to protect consumers, you can bet that I will be working to update our laws to provide that,” she says.
While some diaper manufacturers have already taken steps to voluntarily share their ingredients online or on packaging before the legislation was enacted, now all diaper makers will be required to do so if they want to continue selling diapers to families in New York. If a company fails to comply with the law, it may face a penalty of 1 percent of its annual in-state sales, not to exceed $1,000 per diaper package, as stated in the law text.
If you’re buying diapers in New York state and find that there is no ingredients list on the package, you can file a report with the Office of the N.Y. Attorney General, Rosenthal says. She doesn’t anticipate many diaper companies not complying with the law. “In 2019, I passed the first-in-the-nation law requiring ingredient disclosure on packages of menstrual products, and we have not seen major compliance issues,” she says.
And if your baby has an issue with the diapers they’re using, you can always report product safety concerns on the Consumer Product Safety Commission’s SaferProducts.gov.
