Is talcum powder harmful to humans when exposed to it for a long time

Harmful. Stone powder is closely related to asbestos, a potent carcinogen. Talcum powder particles have been shown to cause tumors in the ovaries and lungs of cancer patients. For nearly 30 years, scientists have been closely examining talcum powder particles and have discovered dangers similar to asbestos.

In 1973, the U.S. Food and Drug Administration (FDA) responded to this evidence by drafting a resolution to limit the amount of asbestos fibers in cosmetic-grade talc.

However, no official decision has been made, and cosmetic-grade talcum powder remains exempt from federal** regulation. This idleness ignores the 1993 National Toxicology Project report, which found that cosmetic-grade talcum powder, which does not contain any asbestos fibers, caused tumors in animal study subjects.

Obviously, cosmetic-grade talcum powder, with or without asbestos fibers, is a carcinogen.

Long-term exposure to these objects is definitely harmful to the human body, so you should take more precautions and go to the occupational disease prevention and control center for regular testing.

Long-term inhalation of talcum powder can cause serious lung damage.

It is non-toxic, non-carcinogenic, and it is not good to eat more.

What's the harm, no one will eat it as a meal, it's just an additive, just like you have to add water to cook rice.

Talcum powder is a chemical raw material and a kind of Chinese herbal medicine, toxic but only slightly toxic, a small amount of contact is generally not much harmful to the human body.

It doesn't hurt much, because the raw material of talcum powder is talcum powder, but children should try not to use it.

There is no obvious harm to the body, so you can use it with confidence, but be sure to apply it according to the instructions.

The harm of talcum powder is mainly due to the possibility of carcinogenicity. Talcum powder is often used externally, for prickly heat, eczema and other parts, for clearing heat and dampness, and is often used as a medium for massage and other techniques. Most of the talcum powder and prickly heat powder for daily consumption are talcum powder as the main ingredient.

However, talcum powder has been confirmed to be toxic. Researchers have found that talcum powder is associated with the onset of ovarian cancer and lung cancer, and that talcum powder particles will be deposited into the ovaries after entering the human body, causing cancerous changes in ovarian cells. Talc, which contains silica, can lead to a significantly higher risk of lung cancer and other respiratory diseases if inhaled into the lungs. The toxicity of talcum powder is certain, so it is recommended that you can reduce the frequency of eating talcum powder and other talcum powder-containing substances in your daily life, and you can choose to use calamine lotion instead.

If you eat too much talcum powder, there will be carcinogenic ingredients, although there are many benefits, it should also be in moderation.

Under normal, reasonable and foreseeable conditions of use, it will not cause harm to human health.

Professor Li Qiong, former vice chairman of the National Technical Committee for the Standardization of Fragrances, Flavors and Cosmetics, said that talcum powder is widely used in various cosmetics, especially powdered cosmetics, and will not cause harm to human health under normal, reasonable and predictable use conditions according to the existing relevant regulations.

She said that as long as it is produced by regular manufacturers, purchased through formal channels, and strictly supervised and tested by national regulatory agencies, talcum powder products for cosmetics can be used with confidence without unnecessary panic.

Li Qiong said that in the natural environment, some talc and asbestos ore are mostly associated or symbiotic, and some industrial talc raw materials with insufficient purity are easy to mix into asbestos, and asbestos is a known carcinogen.

Therefore, talcum powder for cosmetics is a high-quality, high-purity cosmetic raw material that has been rigorously tested. The cosmetics testing standards issued by the regulatory authorities of various countries clearly require that "asbestos shall not be detected" in talcum powder used in cosmetics.

No, talcum powder itself is harmless to humans, so it is also added to food, medicine and cosmetics to beautify the color and improve the taste or feel.

However, as talc is a natural ore, unfiltered natural talc powder may contain asbestos, which can be harmful to health when inhaled into the lungs, so it is not suitable for direct use. At present, the European Union requires all baby products and chemicals containing talcum powder to use filtered talc to avoid asbestos.
