SUPPLEMENTARY INFORMATION:

I. Background

    Talc is used in a wide variety of consumer products, including 
cosmetics. Talc is mined as a naturally occurring hydrous magnesium 
silicate and may be contaminated with asbestos fibers due to the 
proximity of asbestos to talc deposits. Asbestos is a known human 
carcinogen, and its health risks are well documented. Inhalation of 
asbestos is a safety concern because it can cause the formation of 
scar-like tissue in the lung, resulting in asbestosis, or it may lead 
to the development of lung cancers and malignant mesothelioma.
    In 1976, the cosmetics industry implemented voluntary asbestos 
testing of talc raw materials using the Cosmetic, Toiletry, and 
Fragrance Association (CTFA) J4-1 (Ref. 1) method in response to test 
results indicating asbestos to be present. Talc suppliers to the 
pharmaceutical industry use a similar method to certify that talc meets 
the United States Pharmacopeia's (USP's) requirement for ``Absence of 
Asbestos'' (Ref. 2). To date, both methods, which rely on the use of x 
ray diffraction (XRD) or infrared (IR) spectroscopy followed by 
polarized light microscopy (PLM) only if XRD or IR is positive for 
amphibole or serpentine minerals in talc, remain standard test methods 
despite long-recognized shortcomings in specificity and sensitivity 
compared with electron microscopy-based methods. In 2010, FDA asked the 
USP to consider revising the current tests for asbestos in talc to 
ensure adequate specificity, and, in 2014, the Talc USP expert panel 
recommended an update of the Talc USP monograph to require an electron 
microscopy method for the measurement of asbestos in talc (Refs. 3 and 
4). Recent testing of cosmetics by private laboratories \1\ using 
transmission electron microscopy (TEM) has revealed the presence of 
asbestos fibers in samples that had negative findings for the same 
products using polarized light microscopy, thus highlighting the 
shortcomings of optical microscopy methods.
---------------------------------------------------------------------------

    \1\ See AMA testing results at FDA's Investigation of Reports of 
Asbestos Contamination in Cosmetics 2017-2019 tab at https://www.fda.gov/cosmetics/cosmetic-ingredients/talc.
---------------------------------------------------------------------------

    FDA monitors for asbestos in talc-containing cosmetic products, 
including directing its sampling of products toward confirming reports 
from various laboratories that have reported asbestos using electron 
microscopy. For example, in 2010, shortly after reports of asbestos 
contaminated talc-containing products in Asia, FDA surveyed 34 cosmetic 
products,\2\ including body powders, face powders, foundation, eye 
shadow, blush, and samples from four major talc suppliers and found no 
asbestos contamination using the most sensitive techniques available. 
FDA's survey was limited in scope but served to provide data from 
testing using TEM, currently regarded by many experts as the most 
reliable technique for detecting asbestos fibers (see Ref. 4). In July 
2017, FDA began investigating reports of asbestos contamination of 
cosmetic products that contained talc, presumably originating from talc 
that was used as an ingredient in the cosmetic products. In 2019, FDA 
surveyed 50 talc-containing cosmetic products. In March, June, August, 
and October 2019, FDA confirmed the presence of chrysotile and/or 
tremolite asbestos in several cosmetic products, which were voluntarily 
recalled by the companies. The use of TEM was critical in detecting 
asbestos in these cosmetic products.

---------------------------------------------------------------------------

    Even when using the most sensitive electron microscopy methods, 
laboratories testing the same product may reach different conclusions 
about the presence of asbestos. These differences may be attributed to 
a lack of a uniform standard for testing which provides unambiguous 
guidelines for identifying and counting asbestos fibers. Thus, at FDA's 
request, on November 28, 2018, the Joint Institute for Food Safety and 
Applied Nutrition (JIFSAN) convened an ``Asbestos in Talc'' symposium 
to provide a forum for experts in asbestos mineral analysis, 
academicians, and government officials to share knowledge and 
experience.\3\ The discussions focused on the toolbox of available 
testing methods for analysis of asbestos in talc and talc-containing 
cosmetic products, criteria used for asbestos fiber identification and 
counting in current published methods, and how analytical microscopy 
data might be interpreted in making decisions about the suitability of 
cosmetic products found to contain asbestos and other potentially 
harmful mineral particles.

---------------------------------------------------------------------------

    During the fall of 2018, FDA formed an interagency working group on 
asbestos in consumer products (IWGACP). The IWGACP consists of 38 
subject matter experts from the following U.S. federal agencies: FDA, 
National Institute for Occupational Safety and Health (NIOSH), National 
Institutes of Health/National Institute of Environmental Health 
Sciences, Occupational Safety and Health Administration, Environmental 
Protection Agency, Consumer Product Safety Commission, National 
Institute of Standards and Technology, and Department of Interior's 
U.S. Geological Survey. The IWGACP was asked to support the development 
of standardized testing methods for asbestos and other mineral 
particles of concern that could potentially affect consumer product 
safety. The IWGACP was tasked to address terminology and definitions of 
asbestos and other EMPs of health concern in talc and talc-containing 
consumer products, recommend methodological improvements for measuring 
asbestos in talc and talc-containing consumer products, and recommend 
laboratory reporting standards for testing talc and talc-containing 
consumer products. The IWGACP is also addressing issues regarding 
asbestos contamination in talc-containing cosmetic products, the 
presumptive source of asbestos, as well as scientific and technical 
information shared at the JIFSAN Symposium and how that information 
could be used by different government agencies. The IWGACP is comprised 
of three subgroups formed to address the following topics: (1) 
Terminology and definitions of asbestos and other EMPs of health 
concern in talc; (2) development of a robust analytical protocol for 
detecting asbestos and other EMPs of health concern in talc and 
consumer products containing talc; and (3) data reporting and analysis.

II. Purpose of the Public Meeting

    FDA is interested in obtaining information to further the 
development of standardized testing methods to improve sensitivity, 
consistency, and inter-laboratory concurrence of asbestos testing of 
talc used in cosmetic products and of talc-containing cosmetic 
products. Toward this end, at the public meeting, IWGACP members will 
present preliminary recommendations (summarized in section IV.C) on 
testing methods, including criteria to be used for asbestos fiber 
identification and counting. We will also seek additional information 
on these topics at the meeting. We do not intend for this meeting to 
produce any decisions or new positions on specific regulatory 
questions. However, we expect this meeting to be an important step in 
our continued efforts to gather information, including data to improve 
the consistency in terminology, analytical protocols, and data 
reporting for

[[Page 1319]]

asbestos and other potentially harmful mineral particles that may be 
present as contaminants in talc and cosmetic products containing talc 
and provide information that can be used for future discussions on 
health effects.

IV. Issues for Consideration and Request for Information

    We encourage public comments and presentations at the public 
meeting. In submitting information to the docket, please provide 
available references for the information.

A. Testing Methodologies and Criteria

    As previously discussed, laboratories may reach different 
conclusions as to whether asbestos and other potentially harmful EMPs 
are present when testing consumer products. We are seeking scientific 
information on the following topics related to testing methodologies 
and criteria that can be applied to characterize and measure asbestos 
and other potentially harmful EMPs present as contaminants in talc and 
cosmetic products manufactured using talc as an ingredient. We invite 
comments on the following:
    1. The sensitivity of PLM as a test method, including whether the 
test method can lead to a false negative result for asbestos particles.
    2. The sensitivity of TEM as a test method, including the ability 
of the test method to identify asbestos particles in comparison to PLM.
    3. Criteria for identification of the specified asbestos minerals, 
noting that different minerals with the same chemical composition can 
exist in samples.

B. Research Needs To Promote the Reliability of Analytical Methods

    The IWGACP identified the following as areas for directing efforts 
to promote reliability of the analytical methods for asbestos and other 
EMPs of health concern in talc and talc-containing consumer products. 
We invite such information to be presented during the public comment 
section of the meeting:
    1. Validation of analytical methods (XRD, PLM, TEM) specific to 
talc and cosmetic products containing talc that minimize false positive 
and false negative results.
    2. Research and validation of methods of sampling that maximize 
sample representativeness and minimize error and false positives and 
false negatives.
    3. Research on methods for sample preparation, in particular 
treatment (e.g., ``concentration methods'') that improves sensitivity 
while leaving covered minerals unchanged with respect to identity and 
dimensions.
    4. Development of talc-specific reference standards with known 
concentrations of specific EMPs that can be used to assess laboratory 
and analyst proficiency, increase inter-laboratory concurrence in 
method validation, minimize reporting errors, and potentially provide 
for improved reliability of quantitative analysis.

C. IWGACP's Preliminary Recommendations

    We invite comments related to the following preliminary 
recommendations from the IWGACP:
    1. Adoption of the term EMP as ``any mineral particle with a 
minimum aspect ratio of 3:1'', consistent with how this term is defined 
in NIOSH Bulletin 62 (Ref. 5).

[[Page 1320]]

    2. Testing laboratories should report all EMPs having length >=0.5 
micrometers (500 nanometers (nm)).
    3. Test methods should specify reportable EMPs identified as 
amphibole or chrysotile particles as covered minerals.
    4. Test methods should include the counting and reporting of 
covered EMPs as a function of sample mass. In counting, guidelines such 
as ISO 10312, ``Ambient air--Determination of asbestos fibres--Direct 
transfer transmission electronic microscopy method'' (Ref. 6), classify 
primary and secondary structures. Individual fibers in secondary 
structures can be counted recording the dimensions of each fiber.
    5. Use of TEM at nominally 20,000 x magnification, in addition to 
PLM, to resolve the issues of sensitivity that cause reporting of false 
negatives for covered EMPs. Use of TEM with energy dispersive x ray 
spectroscopy and selected area electron diffraction analyses may 
reliably detect and identify chrysotile and asbestiform and non-
asbestiform amphibole minerals, including EMPs whose narrowest width is 
<200 nm. Scanning electron microscopy might be useful as a 
complementary method, but has significant shortcomings for 
identification of chrysotile and visualization of the narrowest 
particles in the population that can only be overcome by using TEM.
    6. ``Mass percent'', a unit that is frequently used to express 
content of asbestos in commercial bulk materials, is not appropriate 
for measurement of EMPs in talc and consumer products containing talc 
because mass percent does not correlate with the number of fibers, and 
one large fiber could dominate the mass percent value.
