The U.S. Food and Drug Administration (FDA) has scheduled a public meeting to discuss testing for asbestos contamination due to concerns about talc in cosmetics and baby powder. The meeting will be held on Tues., Feb. 4 at the agency’s White Oak Campus in Silver Spring, Md. from 8:30 a.m. to 5 p.m.

Among the topics on the agenda are recommendations to define what constitutes asbestos, other potential contaminants, and the development of testing standards in order to improve the accuracy of asbestos tests.

Definition of Asbestos?

While the need to define what asbestos is may seem odd and unnecessary, the fact is that asbestos is not a single mineral. Asbestos is a general term used by geologists to describe six different silicate minerals, characterized by their fibrous structure and flame resistant properties. Not all of these have been used commercially, and two asbestos varieties – crocidolite (blue) and tremolite (brown) – have been banned in most Western countries as well as Japan.

Chrysotile, or white asbestos, is still mined, processed and used around the world. Although U.S. law prohibits domestic asbestos mining and production, it may still be imported from countries such as China and India, which continue to have thriving asbestos industries.

How Did Asbestos Contaminate Talc in Cosmetics?

Asbestos-related illnesses have long been recognized as an occupational hazard for talc miners. The reason is that chemically, asbestos and talc are similar, formed as a result of the same geologic processes. As a result, it is not uncommon for asbestos to occur near talc mining operations.

The specific types of asbestos found in talc deposits tend to be tremolite (the brown asbestos referred to above) and anthophyllite, a ferrous (iron-containing) form of the mineral. Both of these are classified as amphiboles and are especially deadly when inhaled or ingested. They are made up of microscopic needles that literally drill their way through lung and organ tissue from the inside out. In the process, which can take years or even decades, these needle-like fibers create chronic inflammation as antibodies attempt to attack them. Over time, this process causes DNA mutation that results in mesothelioma, a cancer of the visceral lining surrounding the lungs, heart, digestive tract and other internal organs.

Talc in Cosmetics

In addition to baby powder, talc in cosmetics has been found in:

• blush
• eye shadow
• face powder
• foundation
• lipstick
• mascara

Talc may also be found in theatrical makeup, children’s products as well as some food, drugs, and supplements. In some cases, talc may be listed as talcum powder or magnesium silicate on product ingredients. Any of these pose a risk of asbestos contamination.
