The U.S. Food and Drug Administration (FDA) has announced a proposal establishing standardized testing methods for identifying and detecting asbestos in cosmetic products containing talc. This measure responds to requirements set forth in the Cosmetics Regulatory Modernization Act of 2022 (MoCRA).

What does this new regulation entail?
The draft rule, titled “Test Methods for Detecting and Identifying Asbestos in Cosmetic Products Containing Talc,” proposes requiring manufacturers to analyze their talc-containing products using specific methods.
If adopted, this regulation would ensure that cosmetic products do not contain traces of asbestos, a known human carcinogen. The ultimate goal is to protect the health of consumers by reducing the risk of asbestos-related diseases.
Currently, the FDA does not require specific methods to test for asbestos in cosmetic products. Under this proposal, manufacturers will be required to employ advanced techniques such as Polarized Light Microscopy (PLM) and Transmission Electron Microscopy combined with Energy Dispersive Spectroscopy and Selected Area Electron Diffraction (TEM/EDS/SAED).
Talc and Asbestos Risk: Important Context
Talc, a mineral widely used in cosmetics for its smooth texture and absorbent properties, is mined where it is often found near asbestos. This proximity poses an inherent risk of contamination. Since asbestos is a known carcinogen that can cause serious diseases such as mesothelioma and lung cancer, the presence of even small amounts in cosmetic products is a cause for concern.
Until now, there was no mandatory standard in the United States to test for the presence of this contaminant, leaving a regulatory gap that could have put consumers at risk.
Background and scientific support
This proposal is supported by scientific opinions from an Interagency Working Group on Asbestos in Consumer Products (IWGACP), established in 2018. In 2020, during a public meeting, the initial findings of this group were presented and finally compiled into a peer-reviewed technical document in 2022.
Why are Advanced Methods like PLM and TEM/EDS/SAED Necessary?
Traditional asbestos detection methods often lack the sensitivity needed to identify minute traces of the mineral in complex products such as cosmetics.
Polarized Light Microscopy (PLM): This method allows the detection of mineral fibers through optical analysis. While useful, it does not always accurately distinguish between asbestos and other similar minerals.
Transmission Electron Microscopy (TEM/EDS/SAED): This is more advanced and precise, combining chemical and structural analysis to specifically identify asbestos at the microscopic level. This technique is especially effective on very small samples, making it ideal for cosmetics.
The joint use of these methods ensures a more rigorous and reliable approach , strengthening the ability of testing to protect the consumer.
What is expected from manufacturers?
Manufacturers will be required to carry out tests on representative samples of each batch of product or on the talc used as an ingredient. Alternatively, they may rely on certificates of analysis provided by their suppliers, provided that they verify the reliability of these documents by means of additional tests.
Failure to comply with these provisions could result in a product being considered adulterated under the Federal Food, Drug, and Cosmetic Act (FD&C Act). If asbestos is detected in a cosmetic product or the talc used to make it, it will be declared unfit for distribution.
Impact of Regulation on the Cosmetics Industry
Implementation of this regulation will require cosmetics manufacturers to adjust their quality control processes. Key challenges include:
Compliance Costs: The need for specialized equipment and trained personnel to carry out testing can represent a significant expense, especially for small and medium-sized businesses. However, these costs are expected to be offset by reduced product recalls and reputational damage.
Greater Transparency in the Supply Chain: Manufacturers will need to work more closely with their talc suppliers to ensure that raw materials meet established purity standards. This could strengthen trust between companies and consumers.
Boosting Consumer Confidence: With previous scandals involving talc and its safety, this regulation could be an important step in regaining consumer confidence in products that have historically been questioned.
