How toxic are aluminum salts in deodorants?? And how do they work?
Antiperspirants are supposed to help against sweating by closing the sweat glands of the skin with the aluminum chloride they contain. However, aluminum salts are controversial: among other things, they are suspected of increasing the risk of breast cancer.
Not everyone wants to use an antiperspirant with aluminum chloride (aluminum chloride hexhydrate, ACH). Especially since until recently the substance was suspected of having a negative effect on health. The German Federal Institute for Risk Assessment (BfR) ied a statement on 20. June 2020 all-clear given for the use of such deodorants. The statement says: "Significantly less aluminum is absorbed through the skin than calculated on the limited data available to date", says Professor Dr. Dr. Andreas Hensel, President of the BfR. But how does ACH work in antiperspirants?? And what alternatives are there?
How does aluminum chloride against sweating?
Those who sweat frequently and heavily under the armpits can try an antiperspirant or antiperspirant instead of a deodorant. Manufacturers promise that the aluminum chloride contained in it helps against sweating. But the mode of action has its reason: in fact, it closes the glandular excretory ducts, suppressing the production of sweat and thus the formation of odor. An effect is noticeable even at low doses.

Usually pharmacies even offer an antiperspirant, usually a solution based on 20 percent aluminum chloride hexahydrate. Depending on the part of the body where the antiperspirant is to be applied, the concentration may vary. Antiperspirants. Deodorants – what is the difference? Even though no distinction is usually made in everyday language, antiperspirants and deodorants are two different products: While antiperspirants are intended to prevent or reduce sweating, deodorants primarily neutralize the odor of perspiration. For this reason, aluminum salts, due to their antiperspirant effect, are only found in antiperspirants, not in deodorants. However, a "48-hour deodorant" is not a good idea and "72-hour deodorant in most cases an antiperspirant.
Does aluminum chloride in antiperspirants cause breast cancer??
After a study was published linking aluminum chloride to breast cancer risk, the use of aluminum salts is controversial. In 2001, researchers found that breast cancer occurs more often near the armpit, and in 2007 it was discovered that these tumors had increased concentrations of aluminum. It was suggested that salts containing aluminum promote breast cancer. According to the German Cancer Society, however, aluminum-containing deodorants have not been proven to cause breast cancer.
According to an epidemiological study by the University of Medicine, intensive use of deodorants containing aluminum several times a day at a young age can increase the risk of developing breast cancer. Researchers compared 209 cases of breast cancer patients with 209 healthy women. The concentration of aluminum in breast tie was examined in 100 women. The scientists concluded that women who regularly use deodorants containing aluminum probably have an increased risk of breast cancer. Increased levels of aluminum were also found in the breast tie of women with cancer.
The German Federal Institute for Risk Assessment (BfR) stated in a revised statement on aluminum chloride hexhydrate in deodorants of 20.07.2020, that while ACH exposure remains too high in some populations, antiperspirants containing aluminum chlorohydrate contribute much less to this than previously suspected.
Link to nerve damage and Alzheimer's disease
Various studies suggest a connection between the ingestion of aluminum chloride and the development of Alzheimer's disease. In addition, the metal is suspected of having effects on bone development. And according to the European Food Safety Authority (Efsa), long-term increased intake of the metal can also lead to brittle bones, anemia and brain damage.
According to the German Federal Institute for Risk Assessment (BfR), it has been proven that high amounts of aluminum can damage nerves and offspring, i.e. have reproductive toxic effects (effects on fertility and children in the womb). Researchers from Australia and the UK have presented work on the possible risk of breast cancer and Alzheimer's disease from aluminum. It is therefore not possible at present to state with certainty that aluminum causes nerve damage and/or Alzheimer's disease, but must await the results of future studies.
What are the disadvantages of antiperspirants??
Deodorants containing aluminum chloride can also cause another problem: The substance dries out the skin and makes it more susceptible to irritation. Many people experience discomfort such as burning or itching after application. The higher the concentration of active ingredient, the more likely such side effects are to be expected. A 20 percent solution can already cause skin irritation.
You should only apply the antiperspirant thinly and observe how well your skin tolerates the active ingredient.
Aluminum is also found in other cosmetics
Many consumers already ingest high amounts of aluminum through food, and the weekly tolerable intake level is probably exhausted in part of the population through food alone, BfR explains. Lipstick and eye shadow, toothpaste and sun creams can also contain aluminum. The light metal can also be transferred to food via cooking utensils, cans, foils and tubes and thus enter the body.
So make sure that you do not apply antiperspirants containing aluminum immediately after shaving, and it is best not to use them on damaged underarm skin in the first place. This allows the ACH to enter the body more quickly. Deodorants entirely without aluminum salts are also a way to reduce your overall intake of aluminum. Numerous manufacturers now offer these products.
Which deodorants do not contain aluminum?
The list of deodorants without aluminum has been growing steadily for years. You can easily see from the ingredient list whether aluminum is contained in the product. A complete overview can be found on the page "deoohnealuminium".de". Also the own brands of the drugstore chains. Discount products are often made without aluminum salts.
