Are deodorants with aluminum dangerous?

For years, experts have been advising careful handling of aluminum-containing cosmetic products such as deodorants or creams. These are suspected of increasing the risk of diseases such as cancer and dementia. However, this danger has not yet been scientifically proven.

No reliable evidence of serious health risks For years, increased intake of aluminum has been associated with the development of diseases such as breast cancer and Alzheimer's. Above all, the use of aluminum-containing deodorants and other cosmetics is viewed critically. So far, there is no reliable evidence that aluminum deodorants can cause cancer or dementia. However, it is known that if there is hypersensitivity to some ingredients, an itchy rash or allergies can be caused. Those who use deodorants can fall back on aluminum-free products. According to experts, these are the healthier alternative, even if, in contrast to the deodorants with aluminum salts, they do not completely close the sweat glands.

Aluminum-containing deodorants not on freshly shaved skin The question of how dangerous aluminum-based deodorants really are is being explored in a current article. The Berlin Federal Institute for Risk Assessment (BfR) advised caution about a year ago due to the uncertain facts. So you should only apply aluminum-free deodorants to freshly shaved skin to keep the load low. The industry association for body care and detergents has been recommending the members of the "Welt" since 1973: "spray directly on clean, dry, intact - healthy or healthy - skin!" However, only a few print the voluntary warning on their products.

Limit value for aluminum in cosmetics required The BfR is now going one step further and no longer requires only the voluntary printing of warnings on deodorants, but even a limit value for aluminum in cosmetics in general. A study by Alain Pineau from Nantes, France, found in 2012 that significantly more aluminum passes through slightly injured skin than through intact ones. The scientist had tested deodorant sticks, rollers and sprays on isolated skin samples and also applied the stick to damaged skin, which he had previously injured as easily as any shave. It took place instead of 1.81 micrograms per square centimeter, suddenly 11.50 micrograms per square centimeter.

Harmful effects of aluminum The harmful effects of aluminum have also been shown in older studies. According to the “Welt”, researchers discovered in 2001 that breast cancer often occurs in the part of the breast that lies towards the armpit. In 2007, scientists found more aluminum in the tissue of such tumors than elsewhere. Some concluded that deodorants cause cancer, but other experts quickly disagreed. The higher content is related to the denser growth of the tissue in this breast region. In addition, healthy and cancer tissue from patients contained an equally high aluminum concentration. According to the article, only one study shows that women are more likely to develop cancer if they consume a lot of aluminum, but two studies have disproved this connection.

Higher aluminum concentration in samples from dementia patients It is said that scientists have found aluminum in higher concentrations in tissue samples from dementia patients and therefore suspect that the light metal favors the aging disease. In experiments with mice, it was found that the metal - in very high amounts - damages the nerve cells by clumping the so-called tau proteins, similar to what happens in dementia diseases. "When dialysis of kidney disease became popular forty or fifty years ago, the first patients died after half a year," said toxicologist Robert Yokel of the University of Kentucky. "They died of dialysis dementia, which was caused by aluminum in the dialysis fluid."

Brain-damaging effect Patients with impaired kidney function are particularly sensitive to the foreign substance, since the kidneys usually filter the metal salt out of the blood. Despite the evidence that aluminum has a brain-damaging effect, even after decades of research, Yokel admits: “We don't know whether it causes Alzheimer's disease in small quantities. It could be that the accumulation of aluminum in the head of dementia patients is a consequence, but not the cause. ”The BfR also believes that it has not been proven that aluminum causes Alzheimer's disease. Aluminum is also taken up in toothpaste in the form of aluminum fluoride, albeit in very small quantities. The use of aluminum foil for food storage can also be problematic, as aluminum-containing substances can dissolve and pass into the food. Since deodorants are used daily, they pose a greater potential risk. (ad)
