The lawsuit, reportedly filed in Los Angeles County Superior Court, claims the feminine hygiene products contained perfluorooctanoic acid (PFOA), a synthetic substance belonging to a group of chemicals known as PFAS, or ‘forever chemicals’.

The plaintiffs claim they regularly wore the liners for extended periods, sometimes exceeding 10 hours, leaving them in sustained contact with sensitive genital tissue.

‘The tissue is vascular, and permeable, and what it absorbs enters the bloodstream directly,’ the lawsuit states.

The women allege their repeated use exposed them to PFOA hundreds or thousands of times over several years. They claim to have suffered breast, ovarian and kidney cancer, thyroid disease, chronic inflammation, infections, high cholesterol, immune disorders and reduced fertility.

‘Each plaintiff suffered physical, mental, and emotional pain and suffering, anxiety over her diagnosis and treatment, and loss of enjoyment of life,’ the court papers state.

The allegations have not been proven in court, and the lawsuit does not establish that the products caused the reported illnesses.

PFOA has attracted scrutiny because it can persist in the environment and remain in the human body for extended periods.

The US Environmental Protection Agency has identified evidence linking PFOA exposure to kidney and testicular cancers. Research has also associated certain PFAS with reproductive problems, immune system effects, elevated cholesterol and hormonal disruption.

However, risks depend on factors including exposure levels and duration. The available evidence does not establish that every condition cited by the plaintiffs resulted from wearing the liners.

The complaint accuses manufacturers of concealing the alleged contamination despite having access to testing that could have detected the chemical.

The plaintiffs claim the companies were notified on 6 February 2024 that PFOA had allegedly been detected in Carefree liners but continued selling the products. They also allege sales continued in California after restrictions on intentionally added PFAS in menstrual products took effect on 1 January 2025.

The latest case follows an earlier legal challenge involving Carefree panty liners. In September 2024, environmental group Ecological Alliance sued Edgewell Personal Care Brands in Los Angeles, alleging PFOA had been detected in the products and consumers had not received warnings required under California’s Proposition 65 law.

That case sought warnings and civil penalties rather than compensation for individual illnesses.

The legal actions reflect growing scrutiny of PFAS in consumer goods, including personal care products. California has introduced restrictions targeting these chemicals in cosmetics, textiles and menstrual products.

The women involved in the latest lawsuit are seeking punitive damages intended to punish the manufacturers for their alleged conduct.

Johnson & Johnson, Essity and Gelson’s were contacted for comment, according to reports on the case. The allegations remain subject to legal proceedings, and no finding of liability has been established.
