TALC: Questions and Answers
Q. What is talc?
A. Talc is a mineral, produced by the mining of talc
rocks and then processed by crushing, drying and milling.
Processing eliminates a number of trace minerals from the talc,
but does not separate minute fibers which are very similar to
asbestos.
Q. What kinds of consumer products contain talc?
A. Talc is found in a wide variety of consumer products
ranging from home and garden pesticides to antacids. However, the
products most widely used and that pose the most serious health
risks are body powders Talc is the main ingredient in baby powder,
medicated powders, perfumed powders and designer perfumed body
powders. Because talc is resistant to moisture, it is also used by
the pharmaceutical industry to manufacture medications and is a
listed ingredient of some antacids. Talc is the principal
ingredient home and garden pesticides and flea and tick powders.
Talc is used in smaller quantities in deodorants, chalk, crayons,
textiles, soap, insulating materials, paints, asphalt filler,
paper, and in food processing.
Q. Why is talc harmful?
A. Talc is closely related to the potent carcinogen
asbestos. Talc particles have been shown to cause tumors in the
ovaries and lungs of cancer victims. For the last 30 years,
scientists have closely scrutinized talc particles and found
dangerous similarities to asbestos. Responding to this evidence in
1973, the FDA drafted a resolution that would limit the amount of
asbestos-like fibers in cosmetic grade talc. However, no ruling
has ever been made and today, cosmetic grade talc remains
non-regulated by the federal government. This inaction ignores a
1993 National Toxicology Program report which found that cosmetic
grade talc, without any asbestos-like fibers, caused tumors in
animal subjects.1 Clearly with or without
asbestos-like fibers, cosmetic grade talcum powder is a carcinogen.
Q. What kind of exposure is dangerous?
A. Talc is toxic. Talc particles cause tumors in human
ovaries and lungs. Numerous studies have shown a strong link
between frequent use of talc in the female genital area and ovarian
cancer. Talc particles are able to move through the
reproductive system and become imbedded in the lining of the
ovary. Researchers have found talc particles in ovarian tumors and
have found that women with ovarian cancer have used talcum powder
in their genital area more frequently than healthy women.2
Talc poses a health risk when exposed to the lungs. Talc miners
have shown higher rates of lung cancer and other respiratory
illnesses from exposure to industrial grade talc, which contains
dangerous silica and asbestos. The common household hazard posed
by talc is inhalation of baby powder by infants. Since the early
1980s, records show that several thousand infants each year have
died or become seriously ill following accidental inhalation of
baby powder.3
Q. What about infants?
A. Talc is used on babies because it absorbs unpleasant
moisture. Clearly, dusting with talcum powder endangers an
infant's lungs at the prospect of inhalation. Exposing children
to this carcinogen is unnecessary and dangerous.
HERE ARE THREE THINGS THAT YOU CAN DO:
1. Do not buy or use products containing talc. It is
especially important that women not apply talc to underwear or
sanitary pads.
2. Contact your pediatrician and/or local hospital and
find out if they have a policy regarding talc use and infants.
3. Write to the FDA and express your concern that a
proven carcinogen has remained unregulated while millions of
people is unknowingly exposed.
