FDA proposes testing methods to detect asbestos in cosmetics

The FDA has announced a proposed rule that would require manufacturers of talc-containing cosmetic products to use standardized testing methods to identify the presence of asbestos, a known carcinogen.

Specifically, if the rule is finalized, manufacturers will need to test their products using both polarized light microscopy with dispersion staining as well as transmission electron microscopy/energy dispersive spectroscopy/selected area electron diffraction, according to an FDA press release.

Alternatively, “manufacturers may rely on a certificate of analysis from the talc supplier,” the release added.

“For many years the FDA has been sampling and testing talc-containing cosmetics for asbestos as well as working with our federal partners on efforts to reduce consumers’ risk of exposure to asbestos, a known human carcinogen, from contaminated talc-containing cosmetic products,” Linda Katz, MD, MPH, director of the FDA's Office of Cosmetics and Colors, said in the release. “We have carefully considered the scientific evidence and complex policy issues related to detecting and identifying asbestos in talc and talc-containing cosmetic products. We believe that the proposed testing techniques are appropriate methods to detect asbestos to help ensure the safety of talc-containing cosmetic products.”

Talc is often used in cosmetics and other personal care products for “absorbing moisture, preventing the appearance of caking, making facial makeup opaque, or improving the feel of a product,” the release said. Asbestos can be found in the same types of rocks as talc deposits and may be hard to separate from talc during the mining process, the FDA added.

The FDA is encouraging the public to comment on the proposed rule here. The comment period is open for 90 days.
