Why doesn't aluminum-free deodorant work

How well do deodorants work without aluminum salts?

Deodorants should protect against sweat and, above all, against odor.

Most people find the smell of sweat to be extremely unpleasant and repulsive. Anyone who sweats is considered neglected. The unpleasant odor is caused by the bacterial decomposition of sweat - butyric acid is produced in the process, which creates the typical sweat odor. Deodorants should protect against this.

Antiperspirants contain controversial aluminum salts

There are two different means: deodorants and the so-called antiperspirants. They differ in their effect. Deodorants contain fragrances that are supposed to mask the smell of sweat. A proportion of alcohol should ensure that the bacteria that break down sweat do not multiply as much. Antiperspirants, on the other hand, reduce sweat production: the aluminum salts settle in the outlets of the sweat glands and thus prevent us from sweating.

Many products contain them, but aluminum salts are controversial. Their use is discussed critically because they are absorbed by the body and are supposed to promote the development of breast cancer and Alzheimer's disease. So far, however, there is no sufficient scientific evidence that clearly supports or refutes the health risks. Nevertheless, the Federal Institute for Risk Assessment (BfR) recommends lowering the intake of aluminum as a precaution.

Do not use aluminum-containing deodorants after shaving

Admittedly, if the products are used once a day on healthy skin, no adverse health effects are to be expected. Nevertheless, the recommendation is not to apply products containing aluminum to freshly shaved armpits. Shaving can cause tiny skin injuries through which more aluminum could get into the body.

The list of ingredients shows whether a product contains aluminum salts. In addition, many manufacturers clearly label these products as antiperspirants. However, this is not required by law.

Visite tests aluminum-free products

Since the aluminum salts have come under fire, Visite had test subjects test aluminum-free products: an antiperspirant roll-on deodorant from Vichy from the pharmacy for ten euros and one from Lavera from the health food store for five euros. The product from the pharmacy did better with the tester than the one from the health food store: the test subject had to use the Lavera deodorant roller several times a day in order to feel good about her body.

Two deodorants were also tested: La Roche Posay from the pharmacy for ten euros and Nivea "Fresh Natural" from the drugstore for three euros. Both products performed satisfactorily. The drugstore product burned a bit when applied, but then provided reliable protection all day. The tester found the product from the pharmacy to be very pleasant to use, but also had to be refreshed during the day.

Baby powder and armpit pads aren't for everyone

In addition, another test person assessed the effectiveness of baby powder and armpit pads. Neither product did well. The pads were difficult to position and only soaked up sweat where they were stuck on. The powder prevented the unpleasant smell of sweat, but not the formation of sweat stains.

The antiperspirant effect of sage tea was also not convincing: the test subject even sweated more than before. Regular saunas, on the other hand, help train the sweat glands to secrete less sweat. By shaving the armpit hair, the bacterial load in the armpits and thus the smell of sweat can be reduced.
