We’ve written a lot of benzene posts on this blog over the years, and most of them share a common thread. Plaintiffs find a chemical decomposition byproduct nobody put on a label, dress it up as a corporate conspiracy, and ask a court to do what years of FDA rulemaking declined to do. Every so

Express OTC Preemption Or Your Money Back!!
No, your DDL bloggers are not offering a money-back guarantee—although we suppose offering one would not cost us anything, since reading the blog is free. For enterprises that actually sell products though, the story is sometimes different, and many product sellers do guarantee satisfaction—or your money back. Moreover, when those guarantees are unrestricted, we…
Half-Squeezed: S.D.N.Y Splits the Difference on Heavy Metal Toothpaste Claims
June 25, 2026 was a very good day for preemption. While one hand of the judiciary was busy with the Supreme Court handing down its 7-2 ruling in Monsanto Co. v. Durnell — establishing that FIFRA expressly preempts Roundup state-law failure-to-warn claims, the other hand was quietly doing the same thing with toothpaste. Specifically, the…
Supreme Court Roundup Decision: “Different From” and “In Addition To” Mean What They Say
Ever since we reviewed the Environmental Protection Administration’s (“EPA”) 2019 decision reaffirming its prior conclusion that glyphosate does not cause cancer and, therefore, the “Roundup” herbicide did not warrant any cancer warnings, we have been convinced that state-law claims demanding such warnings were (or should be) preempted – regardless of how pro-plaintiff decisions might seek…
Res Ipsa Loquitor Can’t Save Benzene Class Action
Benzene-based consumer class actions are becoming almost routine. So are their dismissals on preemption grounds. It takes something a little different to make one stand out. The plaintiff in Leonard v. CVS Pharmacy, 2026 WL 986311 (N.D. Cal. Apr. 13, 2026), tried just that, invoking a res ipsa loquitur–type theory to plead “parallel”…
Navarro – Another Benzene Ring Busted
As we have discussed more times than we like, the plaintiffs’ class action cabal, in conjunction with their running-dog Valisure “if it doesn’t have it, we’ll cook it until it does” “testing” laboratory, has targeted various products supposedly containing benzene contaminants. The result has been a plethora of no-injury class actions by plaintiffs who…
Same Theory, Same Result: Benzene OTC Class Action Runs Into the Same Preemption Wall
Today’s case, Kouyate v. L. Perrigo Company, 2026 WL 591874 (W.D. Mich. Mar. 3, 2026), is the latest entry in the ever-growing pile of meritless benzene OTC class actions. This time, the target is acne treatments containing benzoyl peroxide (BPO), with the now-familiar allegation that BPO degrades into benzene during storage and shipping. If…
OTC Preemption Letdown in the Eastern District of Pennsylvania
We’ve blogged a lot recently about preemption and the dismissal of complaints alleging that certain over the counter products, including acne medications, sunscreens, antiperspirants, expectorants, and shampoos contain benzene. Almost a year ago we blogged about the dismissal of an OTC case involving medicated shampoo that allowed plaintiff leave to amend. Today’s decision, Pineda v. Lake Consumer Products, Inc., 2025 WL 2698991 (E.D. Pa. Sept. 22, 2025), is a mixed bag that addresses plaintiff’s amended complaint. It’s about coal-tar shampoos, which are known to include benzene and are subject to an FDA monograph that recognizes the naturally occurring presence of benzene in coal tar. Yet, shockingly, plaintiff filed a class action claiming she would not have purchased the shampoos had she known they contained benzene.

Not too long ago, we tried to extrapolate from a doctoral thesis on quantum dots to lessons for litigation. That “[q]uantum dots are between one-billionth of a meter and one-hundred-millionth of a meter in size” emphasized that “appreciating the scope and scale of what is being discussed can be critical.” In the spate of litigation…
There Is No Established Causation Between Acetaminophen and Autism
“To be clear, while an association between acetaminophen and autism has been described in many studies, a causal relationship has not been established . . . .” That is not your DDL bloggers speaking (although we did add the emphasis). It is not a drug manufacturer speaking, nor any particular doctor or researcher speaking. It…
