Texas Opens Investigation into Lululemon Over 'Forever Chemicals' in Products

On April 13, 2026, Texas Attorney General Ken Paxton issued a Civil Investigative Demand (CID) to Lululemon USA Inc., formally opening an investigation into whether the activewear company's products contain per- and polyfluoroalkyl substances — a family of synthetic compounds commonly called "forever chemicals" because they resist degradation in both the environment and the human body [1]. Paxton framed the action as a defense of consumers who shop at Lululemon expecting premium, health-forward products. "I will not allow any corporation to sell harmful, toxic materials to consumers at a premium price under the guise of wellness and sustainability," Paxton said in a statement [2].

Lululemon, which generated over $11 billion in global revenue during fiscal year 2025 and operates stores across Texas in Houston, Dallas, Austin, and San Antonio, immediately pushed back. "Lululemon does not use PFAS in its products," a company spokesperson said. "The company phased out the substance in FY23, which had been used in durable water repellent products, a small percentage of our assortment" [3]. Shares fell as much as 4.5% following the announcement [4].

The gap between those two positions — an attorney general alleging potential consumer deception and a company insisting it already solved the problem — defines the central tension in a case that sits at the intersection of chemical regulation, consumer trust, and the politics of enforcement.

What Are PFAS and Why Are They in Yoga Pants?

PFAS (per- and polyfluoroalkyl substances) are a group of more than 9,000 synthetic chemicals engineered since the 1940s for their ability to repel water, oil, and stains [5]. In the apparel industry, PFAS have been applied primarily as durable water repellent (DWR) finishes on fabrics — coatings that make rain jackets shed water, hiking pants resist mud, and activewear repel sweat and stains [6].

The "forever" label comes from the carbon-fluorine bond at the core of these molecules, one of the strongest in organic chemistry. PFAS do not break down through normal environmental processes, accumulating in soil, water, and living organisms over decades [5]. Researchers have linked PFAS exposure to a range of health concerns including high cholesterol, reduced immune response, liver damage, pregnancy complications, and certain cancers, though the strength of the evidence varies across specific PFAS compounds and exposure pathways [7].

For Lululemon specifically, the company has acknowledged that PFAS were used in its durable water repellent products — items designed to resist moisture during outdoor activities. The company has characterized this as "a small percentage" of its total product assortment, though it has not disclosed exactly what share of its catalog was affected or the specific product lines involved [3].

What Testing Has Actually Found

Independent testing provides the most concrete data on PFAS levels in Lululemon products, though the available results predate the company's claimed phase-out.

In 2021, the consumer advocacy site Mamavation commissioned testing of activewear at an EPA-certified laboratory using total fluorine analysis — a method that detects the fluorine element common to all PFAS compounds, serving as a broad indicator of PFAS presence. Lululemon Align High-Rise Pants tested at 32 parts per million (ppm) of organic fluorine [8]. For context, California's AB-1817 textile ban, which took effect in January 2025, sets its threshold at 100 ppm of total organic fluorine, dropping to 50 ppm in 2027 [9]. The Lululemon result of 32 ppm falls below even the stricter future threshold, though Mamavation's researchers noted that any detectable fluorine raises questions about PFAS presence.

Across Mamavation's broader testing of 32 pairs of leggings and yoga pants, eight tested positive for fluorine at levels ranging from 10 ppm to 284 ppm — meaning roughly one in four products showed indicators of PFAS [8]. The testing was conducted from the crotch area of the garments, where skin contact is most sustained during exercise.

Among competing brands, results varied. Nike's tested products showed zero detectable organic fluorine, and Under Armour also passed with non-detect results in certain Mamavation tests [10]. Nike and Adidas have both publicly stated they have eliminated all PFAS from their products [10]. Patagonia has said it is "moving in the direction of stopping use of fluorinated finishes" in its outdoor gear, though it has not declared a complete phase-out [10].

The Environmental Working Group (EWG) conducted separate testing in 2022 that found PFAS indicators in a wide variety of garments including rain jackets, hiking pants, shirts, yoga pants, and sports bras from brands including Lululemon and Athleta [11]. A 2022 study also found that more than two-thirds of sports bras and a quarter of leggings tested contained detectable fluorine [12].

However, a significant limitation applies to all of this data: the available independent tests were conducted between 2021 and 2022, before Lululemon says it completed its PFAS phase-out in early 2024. No publicly available independent testing has verified whether current Lululemon products are PFAS-free.

The Dermal Exposure Debate

A critical question for the Texas investigation — and for consumer concern more broadly — is whether PFAS in clothing actually poses a meaningful health risk through skin contact, as opposed to the ingestion routes (contaminated drinking water and food packaging) that have dominated PFAS research.

A 2024 University of Birmingham study found that certain PFAS compounds can be absorbed through human skin, adding weight to concerns about dermal exposure [13]. Heat and friction during exercise may amplify absorption, as sweating can increase the rate at which chemicals penetrate the skin barrier [6].

But the broader toxicology literature is more cautious. A 2026 peer-reviewed critical review published in the journal Risk Analysis examined all available studies on dermal PFAS exposure. The authors found that estimates for human dermal exposure were "generally less than 1 nanogram per kilogram of body weight per day for individual compounds and total PFAS," and that dermal exposures "constituted a small fraction of total PFAS exposure relative to other routes" such as ingestion [14]. Some scenarios modeled exposures exceeding 100 ng/kg-bw/day, but these were outliers rather than typical estimates [14].

This creates a genuine scientific disagreement. Environmental advocates argue that any additional PFAS exposure from clothing adds to an individual's cumulative chemical burden — and that the precautionary principle should apply given the persistence of these compounds. Industry defenders and some toxicologists counter that the dermal route from textiles contributes a negligible fraction of overall PFAS exposure compared to contaminated drinking water, and that regulatory attention would be better directed at those larger sources.

The Texas AG's CID does not specify which PFAS compounds it suspects are present in Lululemon products, nor does it cite any specific health studies linking apparel-based PFAS exposure to documented harm [1].

The Legal Landscape: What Texas Can Actually Do

Paxton's investigation is proceeding under Texas's Deceptive Trade Practices-Consumer Protection Act (DTPA), one of the state's broadest consumer protection statutes. The law prohibits false, misleading, or deceptive acts in the sale of goods, and grants the attorney general's Consumer Protection Division the power to issue CIDs — essentially investigative subpoenas — to compel the production of documents and testimony [15].

The CID directed at Lululemon will examine the company's Restricted Substances List, its internal testing protocols, its supply chain practices, and its chemical management policies, including any third-party testing documentation [1].

If the investigation finds violations, the DTPA authorizes civil penalties of up to $20,000 per violation for public enforcement actions brought by the AG's office [15]. In theory, if each sale of a PFAS-containing product to a Texas consumer were counted as a separate violation, the potential liability could be substantial — though in practice, enforcement actions under the DTPA rarely reach those theoretical maximums. The statute also allows the AG to seek temporary restraining orders and injunctions [15].

For private consumer lawsuits — separate from the AG's action — the DTPA provides for economic damages, and courts can award up to three times economic damages if a defendant is found to have acted "knowingly," plus attorney's fees [15].

The legal standard Paxton's office must meet is whether Lululemon's public claims about its products were deceptive. If the company can demonstrate that it genuinely completed a PFAS phase-out before the investigation began, the AG would need to show either that the phase-out was incomplete, that PFAS-containing products remained on shelves in Texas after the claimed transition date, or that the company's marketing during the period when PFAS were present was misleading in some specific way.

Paxton's office has recent experience with PFAS enforcement: in 2024, the AG filed suit against 3M and DuPont over PFAS misrepresentations in household brands like Teflon and Scotchgard [3].

Paxton's Track Record: Consumer Protection or Political Signal?

The Lululemon investigation does not exist in a vacuum. A joint investigation by ProPublica and The Texas Tribune documented that Paxton has used consumer protection law more than a dozen times in recent years to investigate entities whose activities conflict with his political views or those of his conservative base [16]. Those investigations have targeted organizations offering shelter to immigrants, providing healthcare to transgender teenagers, and promoting workplace diversity initiatives. Not a single one of those investigations was prompted by a consumer complaint, Paxton's office confirmed [16].

Georgetown Law professor Michele Goodwin has called the pattern "a core violation" of the principles underlying consumer protection divisions [16].

The Lululemon case fits a different profile than those politically motivated probes — PFAS regulation has bipartisan support, and chemical safety in consumer products is a traditional consumer protection concern. But the timing and framing raise questions. Lululemon says it addressed the PFAS issue two years before the investigation launched. The CID does not cite any specific consumer complaints, new test results, or identified products currently containing PFAS [1].

Steelmanning Paxton's position: even if Lululemon completed a phase-out, the company sold PFAS-containing products in Texas for years without disclosure, and the AG has a legitimate interest in determining whether those marketing practices were deceptive. If Lululemon marketed its products as wellness-oriented and sustainable while using undisclosed PFAS, that could constitute a deceptive trade practice regardless of when the phase-out occurred.

Steelmanning Lululemon's position: the company identified the issue, added PFAS to its restricted substances list, required third-party testing of all vendors, and completed the phase-out — all before any state investigation. A probe launched after the problem was resolved, without citing current violations, risks looking more like a political headline than a consumer protection action. The company stated: "The health and safety of our guests is paramount, and our products meet or exceed global regulatory, safety, and quality standards" [3].

The Supply Chain Question

Lululemon outsources 100% of its production, with primary manufacturing hubs in Vietnam, China, Cambodia, and Sri Lanka [17]. Key fabric suppliers include Eclat Textile (Taiwan), MAS Holdings (Sri Lanka), and Toray Industries (Japan) [17]. The company publishes its Tier 1 supplier list twice a year, but its Tier 2 and Tier 3 suppliers — the fabric mills and raw material providers where DWR treatments would actually be applied — remain largely undisclosed [17].

This supply chain opacity matters for liability. Under the DTPA, the brand that sells the product to consumers bears responsibility for deceptive marketing claims. But the question of whether Lululemon directly instructed its suppliers to apply PFAS treatments, or whether those treatments were applied by upstream chemical suppliers as a standard textile finishing step, could influence both the factual narrative and any potential penalties. Lululemon has said it now requires all vendors to "regularly conduct testing for restricted substances, including PFAS, by credible third-party agencies to confirm ongoing compliance" [3].

A Regulatory Wave Already in Motion

Data as of Apr 14, 2026CSV

California's AB-1817 and New York's parallel legislation banned intentionally added PFAS in textile products effective January 1, 2025, with California setting a threshold of 100 ppm total organic fluorine (dropping to 50 ppm in 2027) [9]. Minnesota's textile PFAS ban took effect in January 2026 [18]. Maine, Vermont, and Rhode Island have bans scheduled for 2027, with Colorado and Connecticut following in 2028 [18]. In 2025 alone, nearly 350 PFAS-related bills were introduced across 39 state legislatures [18].

Internationally, France banned PFAS in textiles, footwear, and consumer waterproofing agents starting January 2026. Denmark's ban on PFAS-containing clothing and footwear takes effect in July 2026. The EU's broader REACH framework is expected to extend PFAS textile restrictions to all textiles by 2030 [19].

Texas itself has not enacted a PFAS textile ban. Paxton's investigation is proceeding under existing consumer protection law rather than chemical-specific regulation — a distinction that matters because it means Texas is not alleging that PFAS in clothing is per se illegal, but rather that Lululemon's marketing about its products was deceptive.

The Cost of Going PFAS-Free

For the activewear industry, eliminating PFAS is not simply a matter of stopping a chemical application. DWR finishes built on PFAS chemistry have been the industry standard for decades because fluorinated coatings provide unmatched performance in repelling both water and oil simultaneously [6].

Several alternative technologies are in development or early deployment. Water-based and silicone-based finishes can provide water repellency, though often with reduced durability. Hyperbranched polymers create multi-layered moisture barriers. Fluorine-free nanocoatings enhance fabric durability while maintaining breathability. CO₂-based fabric treatments eliminate the need for water or toxic chemicals in the dyeing and finishing process. Plasma treatments modify fabric surfaces at a microscopic level to create water-repelling properties [6].

Brands like Aktiiv have pioneered the use of biobased materials, treating clothing with algae-based finishes for moisture-wicking properties instead of PFAS [20]. But these alternatives generally cost more than conventional PFAS treatments, and the performance gap — particularly for outdoor apparel exposed to sustained rain — remains a point of industry debate.

The cost burden of transition falls unevenly. Large incumbents like Nike, Lululemon, and Adidas have the R&D budgets and supplier relationships to absorb reformulation costs and pressure their supply chains to adapt. Smaller activewear brands, which rely on standard fabric finishes from the same mills, face higher per-unit costs for alternative chemistry and may lack the purchasing power to demand custom non-PFAS treatments [6]. Whether this dynamic accelerates market consolidation — pushing smaller brands out of categories where PFAS-free compliance becomes mandatory — remains an open question as state bans proliferate.

What Comes Next

The Texas CID compels Lululemon to produce documents and potentially testimony related to its PFAS history, testing practices, and supply chain management. The investigation could result in a negotiated settlement, a formal enforcement action, or a determination that no violations occurred.

For the broader industry, the case signals that even companies that have phased out PFAS may face scrutiny over their historical use and marketing. The absence of a federal standard for PFAS in textiles means companies must navigate a growing patchwork of state regulations — with at least seven states on track to have active textile PFAS bans by 2028.

The 2023 class action lawsuit against Lululemon, which focused on alleged greenwashing in the company's "Go Planet" advertising campaign rather than direct health harm, remains a separate legal track [21]. That case alleged Lululemon misled consumers about the environmental friendliness of products that contained non-sustainable materials — a claim about marketing, not toxicology.

Whether Texas's investigation produces evidence of ongoing PFAS use, or instead confirms that Lululemon addressed the issue before regulators arrived, will shape the narrative about corporate accountability in the PFAS era. The answer depends on data that has not yet been made public: current test results from Lululemon's product line, the company's internal timeline for its phase-out, and whether any PFAS-containing inventory remained on Texas store shelves after the transition was supposedly complete.
