SPRINGFIELD – Legislation championed by State Senator Laura Fine to require clear ingredient labeling on diaper packaging has been signed into law, ensuring parents and caregivers have straightforward, reliable information about the products their children use every day.
“Families should have easy access to information about the products their children rely on,” said Fine (D Glenview). “By requiring ingredient disclosure on diaper packaging, this law gives parents greater confidence and helps them make choices that are right for their children.”
Concerns from parents, caregivers, and individuals with sensitivities to fragrances and other chemicals highlighted a gap in consumer information surrounding diaper products. While adults using medical-device-classified diapers are afforded certain ingredient disclosure protections under federal regulations, infant and children’s diapers have not been subject to the same transparency standards.
The newly signed Diaper Labeling Act closes that gap. The law requires manufacturers of disposable and reusable diapers sold in Illinois to list ingredients clearly on product packaging, in descending order of predominance, with exceptions for ingredients present at 1% or less. To protect proprietary information, manufacturers may list confidential or trade secret ingredients by their common or functional names rather than specific chemical formulas.
By improving transparency and helping families identify potential allergens, the law aims to give parents greater peace of mind when selecting products for their children.
“Transparency is one of the most effective consumer protections we can provide,” said Fine. “With clear ingredient labeling, families will be better equipped to avoid products that may contain substances they prefer not to use and make informed decisions with confidence.”
House Bill 4702 was signed into law Friday and takes effect Jan. 1, 2027.
