Three parallel class-action suits filed in US courts in the first half of 2026 have made "clean beauty" a functionally litigated category. Ulta is defending a suit alleging its Conscious Beauty seal has appeared on products containing ingredients on the retailer's own "Made Without" restricted list. No7 is defending a suit alleging biodegradability overstatement on wet wipes. Unilever's Dove is defending a suit over a "0% Aluminium" and "no alcohol" deodorant that plaintiffs allege in fact contains benzyl alcohol.

For most of the last ten years, clean beauty was a positioning trend. The economics were straightforward. Consumers responded to "clean," "natural," and "free-from" language with higher purchase intent and higher willingness to pay. Retailers built merchandising programmes around it. Brands built launches around it. The absence of a formal regulatory definition of "clean" was a feature, not a bug, because it allowed each brand to define the term inside its own storytelling.
That gap between marketing language and formulation reality is now being priced by the plaintiff's bar. This is the moment where "clean" transitions from marketing shortcut to legal claim, and any brand still treating it as the former is running exposure it has probably not modelled.
What the current suits actually allege
The three headline suits share a structure worth reading carefully.
Ulta's Conscious Beauty programme allegedly includes products containing ingredients on Ulta's own "Made Without" restricted list. The suit does not allege that the products are unsafe. It alleges that the retailer's claim, that the products are made without a specific set of ingredients, is contradicted by the products' own ingredient decks. That is a straight consumer-protection argument: the label said one thing, the formula said another, and the consumer paid a premium for the promise.
No7's biodegradability claim on wipes allegedly overstates the extent to which the product breaks down in real-world conditions. The suit turns on the difference between marketing language ("biodegradable") and formal environmental testing standards. This is the same category of claim that the Advertising Standards Authority in the UK has now moved against multiple beauty brands on. In the US, it becomes a class action.
Dove's "0% Aluminium" and "no alcohol" deodorant allegedly contains benzyl alcohol. The suit argues that a reasonable consumer reading "no alcohol" on a deodorant would understand it to mean no ethyl alcohol and no other cosmetic alcohols. That reasonable consumer interpretation is doing the legal work.
None of these are safety claims. They are consumer-protection claims about the accuracy of marketing language. That distinction matters, because it means a brand cannot defend itself with "our product is safe." The defence has to be "our marketing is precisely true."
Why the plaintiff's bar has found this category
Three inputs align. Consumer-protection statutes in California (Business and Professions Code sections 17200 and 17500), New York (General Business Law sections 349 and 350), and Washington (Consumer Protection Act) provide statutory damages and attorneys' fees on top of actual damages. That is the economic engine for a class action.
Beauty marketing routinely uses language that does not have a formal definition. "Clean," "natural," "pure," "green," "safe," "non-toxic," "biodegradable," "recyclable," and "eco-friendly" are all terms where a reasonable-consumer standard invites litigation. The FDA does not define most of them. The FTC has issued guidance ("Green Guides") that is now routinely used as evidence in cases against brands.
Ingredient decks are public. A plaintiff's law firm can read the label of every product a brand sells, cross-reference against the brand's own claims, and identify contradictions without setting foot in a lab. This is low-cost discovery. It is exactly the shape of case a plaintiff's firm wants to bring at scale.
Once one high-profile suit is filed, the template spreads. Ulta's suit is being tracked by every major consumer-protection tracker. The learnings from that suit will be applied to the next twenty brands whose marketing language contains the same shape of gap.
What a £500k-£5m brand should do this quarter
The wrong instinct is to strip all "clean" language from the brand. That is over-reactive and it destroys marketing equity that most indie beauty brands cannot afford to lose. The right instinct is to build the substantiation infrastructure that makes the current language defensible.
Build a claim ladder. For every current SKU, list every marketing claim used in campaigns, on-pack, on the website, and in sales collateral in the last twelve months. Map each claim against its substantiation. That substantiation might be a formulation record showing the ingredient is absent, a third-party test, an accepted industry standard, or a published scientific reference. Where the substantiation is thin or missing, mark it as a priority.
Rank each claim. Verified claims (with a documented file). Weakly supported claims (there is an argument but not documented evidence). Unsupported claims (marketing language that outran formulation, or that was inherited from a prior era of brand storytelling). The list of unsupported claims is the priority backlog for legal review.
Fix the unsupported claims. This is where founders get stuck. There are usually two options for each: change the language, or build the file. Changing the language ("clean" becomes "made without our restricted list") is often the fastest fix and the least commercially damaging. Building the file (third-party testing, formulation records, industry standard evidence) is heavier but leaves the marketing intact. The choice depends on the claim.
Add a claims review to the launch process. Any new campaign, any new SKU launch, and any new landing page should route through a claim review before it goes live. That does not need to be an external law firm. It can be an internal check against the claim ladder. The point is that new marketing does not add new liability.
The economics of prevention versus settlement
The reason to invest six to eight weeks in a substantiation project is that the alternative is expensive.
An early-stage class action settlement in California typically runs from $500k to $3m for a mid-sized brand, before legal fees. The disruption cost, including diverted founder and executive attention, is often multiples of that. The brand equity cost, particularly for a brand whose whole positioning is trust and integrity, is often uncosted and material.
The prevention cost is comparatively small. A properly built claim ladder, a substantiation file, and a review process cost between £15k and £60k depending on brand size and complexity. Most of that cost is time, not fees. For a founder-led indie with five to fifty SKUs, the project fits inside a single quarter with dedicated internal ownership.
That is the maths. It is not close.
The wider frame
The clean beauty movement did real work. It pushed the industry toward better formulation, more transparent ingredient disclosure, and a higher standard of consumer expectation. That is a net positive for the category.
The next phase of the movement is not looser language. It is tighter language, backed by better files. The founders who understand that shift will keep the marketing equity of the last decade while stripping out the legal exposure of the next one. The founders who treat "clean" as a permanent free option will find themselves in a courtroom in the next twenty-four months.
The suits are already filed. The precedents are being set. The claim ladders are being written by the brands paying attention. Q3 is the right quarter to write yours.
