A class-action lawsuit has been filed against Costco Wholesale Corporation and Nice-Pak Products, Inc., alleging that the companies misled consumers about the safety and environmental claims of their baby wipes. The complaint centers on the marketing of Kirkland Signature Baby Wipes, which were advertised as “plastic-free” and made with “Naturally Derived Ingredients.”
According to the lawsuit filed by plaintiff Ella Rosewood, independent testing conducted by Rosewood revealed the presence of microplastics in the wipes. The complaint states that these microplastics may pose potential health risks, particularly to infants and young children, including immune system stress and the potential to contribute to the spread of cancer cells. Rosewood contends that the presence of these materials contradicts the product’s advertised environmental benefits and its suitability for sensitive skin.
The suit alleges violations of consumer protection laws and breaches of express and implied warranties. Rosewood claims that the wipes’ marketing led consumers to believe the product was safe and environmentally friendly, when in fact it contained synthetic materials inconsistent with those representations.
The complaint seeks equitable relief on behalf of a class of consumers who purchased the wipes based on the marketing claims. Rosewood is also pursuing monetary damages, including punitive damages, and a declaratory judgment that the defendants’ practices violate consumer protection statutes in multiple states.
The plaintiff is represented by attorney Kim E. Richman of Richman Law & Policy. The case was filed in the United States District Court for the Eastern District of New York under Case ID 1:25-cv-02892.
