I believe it occurs naturally or can be manufactured. This is the same alum that used to be used in pickles, and it is a powerful astringent. The crystal deodorants, on the other hand, typically contain potassium alum. The industry is complaining due to lack of scientific evidence, but someone at the FDA seems to believe in “prudent avoidance”! those who have trouble shedding environmental toxins) and children should not use these products. The FDA has recently required a new label on antiperspirants saying that people with impaired renal function (i.e. Theoretically the ions are eventually removed from the body in the urine, but research suggests that certain tissues (liver, kidney, brain, cartilage and bone marrow) selectively absorb it. This effect is temporary, as capillaries serving the cell clean up the ions, making daily reapplication necessary for a continued effect. No sweat also means no water for the bacteria, so no odor. The aluminum ions are positively charged and small, which apparently means that they can pass through skin cell membranes, where somehow they either cause the cell to puff up, or help form a physical plug, thereby squeezing off nearby sweat glands. When water from sweat mixes with one of these salts, their component chemicals break apart into “ions”, which are positively or negatively charged. Regular antiperspirant works by having an ingredient off a short FDA list, all of which are aluminum salts. There are many different forms of Alum found in the deodorants, and they tried to market the newest form - Potassium Alum, as the the natural and safe form of it in the new-age deodorants,Īnyways, don't be fooled and avoid all Alum like wildfire, because it is very well absorbed through the skin, and they found that about 0.012% or more is absorbed through every single application,Īnd that is massive, for that value should be Zero. There has been many studies done about the toxicology of Aluminium and it's a well established fact that it is best to avoid any and all of it from reaching inside your body, for more information about its adverse and side-effects, check google. Īluminum ( Aluminium ) is one of the most toxic and well accumulating heavy metals once in the body, it builds a plaque in the brain, and accumulates in the most vital and common organs, - liver, kidneys, etc. The study could help to develop a better understanding of and treatments for skin diseases and synthetic materials based on the properties of skin.Don't get accidentally caught in the new-age hype of crystal deodorants, which contain Potassium Alum ( Potassium Aluminium Sulfate ) as their main ingredient. This means that our skin can give off the water it absorbed and return to a smooth state without taking any damage. The expansion stops before the keratin filaments touch each other and can become permanently interlinked, which would result in a permanent change of the cells’ mechanical properties. This interplay of forces acting in opposite directions brings the expansion of the cells to a halt and ensures that the skin only absorbs a limited amount of water. If the cells swell in the process, the keratin filaments are stretched, which in turn costs elastic energy much like in a coil spring that is pulled. Keratin is hydrophilic, meaning it feels very at home in an aquatic environment, which explains why skin cells absorb water. The outermost layer of skin contains keratin filaments in a geometrically ordered structure. Using a computer model, the scientists calculated the processes that take place in the individual components of the skin when it absorbs water and observed an interesting interplay of forces in the outermost skin cells. The outer skin layer, known as epidermis, consists of dead skin cells but fulfils key functions: for instance, it protects our body from loss of moisture in dry environments and from absorbing too much water when we bathe. Our skin is a complex organ with many different functions. Their results were recently published in the journal Physical Review Letters. Myfanwy Evans and Professor Roland Roth from the Institute for Theoretical Physics at the University of Tübingen modelled the structure of the outer skin layer on the mesoscopic scale for the first time. Researchers have now been able to show how this is possible using a physical model: FAU physicist Dr. Once in a dry environment, the skin gives off the additional water without sustaining any lasting damage and returns to smooth within a short time. If we spend longer periods in the water, our skin absorbs moisture and the cells of the outer skin layer begin to swell. We all know the phenomenon of wrinkly fingers after a bath. Physicists reconstruct how wrinkly skin returns to smooth using a computer model The space between the fibres is filled with water. FebruThe computer model shows the ordered structure of the keratin fibres of the outer skin cells in a contracted (links) and expanded (right) state.
