Illinois lawmakers signed off late last month on a far-reaching cosmetics crackdown that would bar a short list of intentionally added toxic ingredients and a group of PFAS from products sold in the state. The measure cleared both chambers and is now on Gov. J.B. Pritzker’s desk, setting up legal questions about exactly how and when the new restrictions would kick in if he signs it.
What the measure would ban
According to the Illinois General Assembly, House Bill 3409, known as the Chemicals in Cosmetic Products Act, would prohibit knowingly manufacturing, selling or offering for sale cosmetic products that intentionally contain any of 11 named ingredients, including dibutyl phthalate, diethylhexyl phthalate, formaldehyde and mercury. It would also restrict a specified list of PFAS, such as PFOS and PFOA.
The enrolled bill text carves out a narrow exemption for “technically unavoidable trace quantities” and sets July 1, 2028, as the effective date. Supporters say the timing is meant to line up Illinois rules with stricter European chemical standards while giving manufacturers a clear runway to rework formulas and supply chains.
Sponsors frame it as consumer protection
Sen. Mattie Hunter, who carried the measure in the Senate, told the Chicago Crusader that “for too long, the cosmetics industry has operated without the kind of oversight we apply to food, medicine and drinking water.”
Backers in both chambers argued the bill targets products that have long sidestepped the ingredient controls other sectors routinely face. They pitched it as a consumer-safety move and an equity measure in a market where some communities see heavier exposure to certain beauty-product chemicals than others.
Research and equity concerns behind the push
Lawmakers leaned on a growing body of science that flags hazardous chemicals in products used disproportionately by Black women and by salon workers. A February analysis from the Silent Spring Institute found 169 distinct chemicals across 43 hair-extension samples, with many appearing on formal hazard lists.
Federal researchers at the National Institute of Environmental Health Sciences have reported that frequent use of chemical hair-straightening products was associated with higher uterine-cancer risk. A large Boston University study of Black women similarly found that long-term relaxer use was linked to increased uterine-cancer risk among postmenopausal participants. Advocates pointed to those findings as part of the case for tightening up cosmetics rules.
Legal pressure is amplifying the debate
The policy fight is unfolding alongside a sprawling federal mass-tort over hair relaxers. That litigation, centralized as MDL No. 3060 in the U.S. District Court for the Northern District of Illinois before Judge Mary M. Rowland, has grown into the low-five-figure range of federal filings.
This spring, the case moved into a pivotal expert-evidence phase, with defendants pressing Daubert challenges to plaintiffs’ general-causation experts. Advocates and some lawmakers say the courtroom battles have only sharpened public attention on potential harms and the long-standing gaps in cosmetics oversight.
Next steps and the timeline to watch
Legislative records show HB3409 was sent to the governor on June 26, 2026. If signed, the act would take effect on July 1, 2028, as spelled out in the enrolled text.
In the meantime, state agencies and manufacturers have a built-in lead time to sort out enforcement plans, ingredient reformulations and supply-chain changes. The proposal also builds on earlier Illinois action limiting intentionally added PFAS in consumer goods, a change approved in 2025 that starts phasing certain PFAS uses out on a multi-year schedule.
Regulatory watchers are already asking how state officials will prioritize enforcement, which products will draw the closest scrutiny and how the state will interpret what qualifies as a “technically unavoidable” trace amount.
What to watch
Consumer and environmental groups quickly labeled the bill a win for safer products and clearer information for communities that shoulder heavier exposure to some beauty chemicals. Advocacy organizations such as the Campaign for Safe Cosmetics and the Environmental Working Group have documented both the disproportionate hazard ratings and marketing patterns for products aimed at Black women, a disparity lawmakers repeatedly cited as they steered the bill through Springfield.
