When eating, the liver and digestive system process the products, but when you put the chemicals on your skin, they can enter the bloodstream directly, without metabolism ", explains Heather Patisol, Professor of Biology at North Carolina State University.
One of the main ingredients, used in most deodorants isaluminum.
Why aluminum is dangerous to health?
The metal helps to block the sweat glands and reduce odors. Aluminum salts from deodorants and antiperspirants are absorbed directly into the body, connecting with the sweat glands, whose secretion they block. Thus, large amounts of aluminum can penetrate the skin much more easily, than with other cosmetic products.
At high doses, a disorder of the central nervous system can also occur, dementia and memory loss, apathy and severe tremor.
The risk, related to the use of these products, containing aluminum, is bigger, than with other products, as:
Aluminum can be especially dangerous for women, as it stimulates the production of the female sex hormone estrogen, as a result it leads to hormonal imbalance and in some cases to breast cancer and severe damage to the nervous system. Only a few years ago, British scientists unequivocally found a link between the metal and breast cancer. Analyzes showed, that in women, who use deodorants, aluminum accumulates in the outer tissues of the mammary glands.
Propylene glycol is another ingredient, which is used in deodorants. Scientists are divided on two opinions about its safety. Some believe, that in small quantities it does not harm health. Often used, however, propylene glycol can cause damage to the central nervous system, liver and heart.
In most modern cosmetics are present andphthalates. The biggest concern of scientists is, that the compound may impair male fertility and affect fetal development in pregnant women. There are already studies, which point, that phthalates also affect hormonal balance and increase the likelihood of cell mutation.
Deodorants, antibacterial soaps, wet wipes and gels usually contain andtriclosan. Cosmetic manufacturers add this chemical to many products, to prevent bacterial contamination, and to kill bacteria on the surface of the skin. Some animal studies have linked triclosan to extreme hormonal activity.
That is why it is important to be careful with the choice of deodorizing products. Fortunately, there isnatural alternative of known antiperspirants.
