Illinois law removes certain chemicals from cosmetics — formulators await substance list

Illinois has enacted a new law that removes certain chemicals from makeup and personal care products sold in the state, according to reporting carried by KFVS12. The headline-level disclosure identifies the action as a state legislative measure but stops short of naming the chemical inventory, bill number, sponsor, signing date, and effective date — the four data points that will drive the reformulation calendar for brand owners with product on Illinois shelves.

The structural shape of the regulatory action, even at this level of detail, tells trade readers what kind of compliance workload is coming. A state-level chemical ban on cosmetics and personal care products operates outside the federal Modernization of Cosmetics Regulation Act (MoCRA), which set the FDA's baseline authorities over cosmetic product safety, manufacturing, and adverse-event reporting. States retain the authority to restrict substances the FDA has not restricted, and Illinois has built a track record on the file in recent years, layering targeted substance limits on top of the federal floor.

That layered federalism is the headline trade consequence of any new state chemical ban. A national brand does not get to ship one formula and call it compliant; it must run a state-by-state matrix and decide whether to reformulate for the most restrictive jurisdiction or to maintain a regional SKU set. The unit cost of the second option is well understood by retail buyers and account leads; the cost of the first option is reformulation work, safety substantiation, stability re-testing, and a packaging and label review.

What the source confirms and what it leaves open

The source confirms three things and leaves open everything else:

• Confirmed: a new Illinois law exists.
• Confirmed: the law targets makeup and personal care products.
• Confirmed: the operative regulatory effect is the removal of certain chemicals from those products.
• Open: which chemicals.
• Open: under what concentration thresholds.
• Open: from what effective date.
• Open: whether the law carries a sell-through or recall obligation on existing inventory.
• Open: whether the law carries a private right of enforcement.

The unknowns are not minor details. The chemical list defines the scope of reformulation. The thresholds determine whether trace impurities trigger non-compliance or whether a finished product can clear testing with a certificate of analysis. The effective date defines the clock. And the enforcement mechanism determines whether a brand faces a one-time fine or an ongoing plaintiff bar.

What formulation and compliance teams should do this week

• Pull the Illinois General Assembly bill text once it is enrolled and posted.
• Build a CAS-number-level match against the restricted list — not a trade-name match, because trade names vary across suppliers and regions.
• Map each restricted CAS number against the current bill of materials for every SKU shipped to Illinois.
• Cross-reference the restricted list with California Proposition 65, the EU Cosmetics Regulation, and the FDA's voluntary cosmetic ingredient listings; overlaps reduce duplication of effort.
• Confirm whether the law carries labeling or notification requirements that would force a packaging change or a state-specific product listing.
• Re-cut the forecast for raw material orders on any restricted substance to allow time for reformulation, scale-up, and stability re-testing before the effective date.

The next data points to watch

Watch the Illinois General Assembly website for the enrolled bill text, the governor's signing statement, and any agency rulemaking that follows. The restricted substance list, the concentration thresholds, and the effective date will drive the reformulation calendar. Until those three numbers land, R&D cannot scope the project, procurement cannot quote the substitution cost, and regulatory affairs cannot size the compliance workload.

The state is moving; the trade waits for the chemical list.
