Imerys Luzenac Industrial Talc

Product Description

Imerys Talc (formerly Luzenac America) supplied industrial-grade talc from its mining operations in Vermont (Argonaut Mine, Hammondsville) and Montana (Yellowstone Mine, Three Forks complex) throughout the asbestos era. Imerys/Luzenac was the primary U.S. supplier to Johnson & Johnson and many other cosmetic talc brands, and a major supplier to industrial customers in ceramics, paper, paint, rubber, plastics, and pharmaceutical applications.

Imerys Talc America filed Chapter 11 bankruptcy in 2019, establishing an asbestos personal injury trust for claims by workers and consumers with asbestos-related diseases. Workers at the Vermont and Montana mining operations are documented in litigation as having had occupational exposure to asbestos-contaminated talc during mining, milling, bagging, and shipping operations.

Asbestos Contamination

Talc and asbestos are mineralogically adjacent — both are hydrated magnesium silicates that often occur in the same geological deposits. Talc mines worldwide have produced talc that is contaminated with asbestos fiber in varying concentrations depending on the specific deposit. Tremolite, anthophyllite, and actinolite asbestos forms are most commonly found as contaminants in talc; chrysotile appears less frequently.

Publicly filed asbestos litigation has documented that the talc supplied to Imerys Luzenac Industrial Talc’s production line during the asbestos era contained asbestos fiber as a geological contaminant. The contamination was not always disclosed to downstream users — testing methodologies through the 1970s and 1980s often used techniques that did not reliably detect asbestos fiber in talc samples, leading to disputes about historical knowledge of contamination.

How Workers Were Exposed

Litigation records document the exposure pathway for workers who handled Imerys Luzenac Industrial Talc:

Industrial workers: Workers at facilities that received bulk industrial talc — for use as filler, extender, processing aid, or release agent — handled the material in bulk quantities daily. Exposure occurred during bag handling, weighing, blending, transferring, and any operation that aerosolized the talc.

Manufacturing workers: Workers at the Imerys Luzenac Industrial Talc production facilities handled the material during raw material receipt, formulation, blending, packaging, and quality control. The asbestos-contaminated talc was a primary ingredient in their daily work.

Consumers and beauticians (cosmetic talc): End users of cosmetic talc products experienced repeated low-dose exposure during normal product use over years or decades.

Bystander exposure: Workers in adjacent operations or living with workers in the talc supply chain experienced secondary exposure via dust transport on clothing, hair, and skin.
