Antiperspirants work by sealing in moisture and blocking the body’s natural process of sweating. Aluminium compounds, such as aluminium chlorohydrate and aluminium zirconium, are commonly used in antiperspirant deodorants as the active ingredients to block sweat glands and reduce sweating. However, there are concerns about the safety of these compounds and their potential effects on the body.
One concern is that aluminium compounds can be absorbed through the skin and may accumulate in the body over time. Some studies have suggested that aluminium compounds may have negative effects on the nervous system, the brain and the bones. But it is important to note that the majority of these studies were done on animals and the results are inconclusive on the effects on human.
Another concern is that aluminium compounds may have an impact on hormone function, specifically on estrogen receptors, the hormone that is responsible for the development and regulation of the reproductive system. However, the majority of studies on the relationship between aluminium and estrogen receptors have been done in cell cultures, and their results are not conclusive.
Additionally, some studies have suggested that long-term use of antiperspirant deodorants that contain aluminium compounds may be associated with an increased risk of breast cancer, although the evidence for this is not yet clear.
It's important to note that the safety of aluminum in antiperspirant deodorants is still a topic of ongoing research and the results are inconclusive. Some people may choose to avoid products containing aluminum compounds due to these concerns, and opt for natural deodorants instead.
