U.S. FDA Withdraws Proposed Rule on Asbestos Testing for Talc-Containing Cosmetics

Latest Updates:

On November 28, 2025, the U.S. Food and Drug Administration (FDA) issued an unpublished notice titled “Testing Methods for Detecting and Identifying Asbestos in Talc-Containing Cosmetic Products; Withdrawal,” formally withdrawing a previously proposed rule on this subject. The withdrawal took effect upon publication of the notice.²

In the withdrawn proposal, the FDA had considered specifying testing methods for detecting and identifying asbestos in cosmetic products containing talc. By issuing this withdrawal notice, the agency has ended further action on that specific rulemaking, and the proposed testing requirements outlined in the now-withdrawn rule will not move forward.

On December 26, 2024, the U.S. Food and Drug Administration (FDA) announced a proposed rule mandating the testing of talc-containing cosmetic products for asbestos contamination. This initiative aligns with the requirements of the Modernization of Cosmetics Regulation Act of 2022 (MoCRA) and is open for public consultation until March 27, 2025.¹

Talc, widely used in cosmetics for moisture absorption and texture enhancement, can be contaminated with asbestos, a known carcinogen. Currently, there are no specific requirements for asbestos testing in talc-containing cosmetics.

The proposed rule outlines two primary testing methods: Polarized Light Microscopy (PLM) and Transmission Electron Microscopy/Energy Dispersive Spectroscopy/Selected Area Electron Diffraction (TEM/EDS/SAED). Manufacturers of talc-containing cosmetics would be required to test representative samples from each batch or lot of their talc-containing cosmetic products or the talc ingredients used.

Furthermore, manufacturers may rely on a certificate of analysis from the talc suppliers if they can verify the reliability of the supplier’s documentation. Non-compliance with the new testing or recordkeeping provisions could result in products being deemed adulterated under the Federal Food, Drug, and Cosmetic Act (FD&C Act).
