아래 내용은 미국 FDA에서 탈크 분석에 대한 보고서입니다.
탈크와 석면은 자연발생 광물이며 결정구조에 따라 달라지므로 광맥이 비슷한 곳에 위치할 수 있어, 탈크에 석면이 포함될 가능성이 높습니다.
탈크는 보통 화장품과 베이비파우더 등에 사용되는데, FDA에서는 2023년 시중의 탈크 제품에 석면 존재 여부에 대해 테스트를 하였으며 분석 방법과 결과는 웹페이지 첨부되어 있으니 참고하시기 바랍니다.

Talc is an ingredient used in many cosmetic products, from baby powder to blush. From time to time, FDA has received questions about its safety and whether talc contains harmful contaminants, such as asbestos.
FDA's Authority Over Cosmetic Product Safety
Under the Federal Food, Drug and Cosmetic Act (FD&C Act), cosmetic products and ingredients, with the exception of color additives, do not have to undergo FDA review or approval before they go on the market. Cosmetic products must be properly labeled, and they must be safe for use by consumers under labeled or customary conditions of use.
FDA monitors for potential safety problems with cosmetic products on the market and takes action when needed to protect public health. Before we can take such action against a cosmetic product, we need sound scientific data to show that it is harmful under its intended use. Learn more about FDA's Authority Over Cosmetics.
Talc: What it is and How it is Used in Cosmetic Products
Talc is a naturally occurring mineral, mined from the earth, composed of magnesium, silicon, oxygen, and hydrogen. Chemically, talc is a hydrous magnesium silicate with a chemical formula of Mg3Si4O10(OH)2.
Talc has many uses in cosmetic products and other personal care products. For example, it may be used to absorb moisture, to prevent caking, to make facial makeup opaque, or to improve the feel of a product.
Published scientific literature going back to the 1960s has suggested a possible association between the use of powders containing talc in the genital area and the incidence of ovarian cancer. However, these studies have not conclusively demonstrated such a link, or if such a link existed, what risk factors might be involved. More research is needed to confirm if there is a link or not. In addition, questions about the potential contamination of talc with asbestos have been raised since the 1970s.
Asbestos: What it is, Why it is a Concern, and How to Prevent its Occurrence in Cosmetic Products
Both talc and asbestos are naturally occurring minerals that may be found in close proximity in the earth. Asbestos is also a naturally occurring silicate mineral, but with a different crystal structure. Unlike talc, asbestos is a known carcinogen when inhaled. There is the potential for contamination of talc with asbestos and therefore, it is important to select talc mining sites carefully and take steps to test the ore sufficiently.
2023 Testing of Talc-Containing Cosmetic Products for Asbestos
The FDA has continued its testing for asbestos contamination in talc-containing cosmetic products. The products were selected based on various factors including, type of talc-containing cosmetic product, price range, popular products on social media and in advertisements, products marketed to children, and products marketed to women of color and, if any, third party reports of potential asbestos contamination. Testing of samples was conducted by AMA Analytical Services, Inc. (AMA) on behalf of the FDA. Samples were analyzed using polarized light microscopy (PLM) and transmission electron microscopy (TEM).
