I have been using the Crystal deodorant... haha not on my face like others are doing but on my arm pitts.... and it works like a dream!! So naturally I get suspicious about what potassium alum is... I looked it up on the internet and found it on some sites... some say that it is safe and will not penetrate the membrane because it has a negative charge or something like that.... but on other sites it talks about how it is just as bad as the aluminum used in antiperspirants... and I dont want that at all! So really, either it's REALLY safe or REALLY unsafe.... so what is it??? Is there anyone here who can tell me how safe potassium alum is? anyone know chemistry?? Haha.... thanks guys....

Well, mine contains Ammonium Alum...All the articles I've found on its safety say it's safe, and cannot be absorbed into the skin as well...Could you link to some of these studies saying it's unsafe?

I just found this:

"Antiperspirants & Deodorant

The Food and Drug Administration (FDA) does not closely monitor personal care products. Manufacturers are protected by "trade secret" formulas so all ingredients don't even have to be listed on the label. This occurs regularly in perfume and fragrances, for example. Many contain chemicals that can cause allergic reactions as well as cancer and other diseases. Many manufacturers believe that they can include small amounts of poison since at those levels there is no risk. But we use our favorite personal products regularly, compounding that minute amount every day and sometimes more than once each day. Considering that many personal care products, like deodorants and antiperspirants, are created to stay on our bodies for hours, more potential harmful chemicals can be absorbed through our skin and into our body. Therefore it is upon us, as diligent consumers, to get the facts and choose what's safest and best for our bodies. We need to learn the possible effects and safer alternatives.

Spray, stick or roll-on? Aerosol sprays are dangerous so always avoid those. As for stick or roll-on, it's a personal preference. Safety, aside from avoiding aerosols, has more to do with ingredients.

Antiperspirants, even so-called "natural" ones contain aluminum that work to clog our pores and stop us from perspiring. Aluminum is a poison. It has been linked to Alzheimer's disease. There is new research which indicates that there may be a link between breast cancer and antiperspirants. In particular, studies are showing that it travels more freely into our lymphatic system when underarms are shaved. Look on your antiperspirant label for aluminum as:

aluminum chlorohydrate

ammonium aluminum sulfate

potassium alum

potassium aluminum sulfate

mineral salts or crystal

Of less concern is aluminum chloride.

Aside from all the ill effects on our health, mining for aluminum is a destructive business that consumes electricity and destroys our environment.

Not only are we endangering our lives by using chemicals like aluminum, and supporting businesses that destroy our natural resources, but we are also polluting our environment every time we use them. The poisons wash into our water system every time we wash. This harms our future, our delicate ecosystems, and our drinking water.

Ammonium alum is different. It is a prevalent natural compound. It cannot be absorbed into the skin and does not clog pores the way aluminum chloride does. It does not kill the bacteria and does not stop perspiration, however, ammonium alum works to inhibit the growth of bacteria and therefore those critters that cause bad odor. This is the primary ingredient in deodorant crystals which are found to be safe and effective.

Aside from aluminum, a potential allergen in most antiperspirants is Zinc or Zirconium. Parabens (Proplyparaben, Methylparaben) are regularly used in personal care items including antiperspirants and deodorants as a preservative. These are hormone disrupters that can be harmful in certain quantities, and many people have an allergic reaction to these. APEs, Triclosans, Formaldehyde, Dioxane, Propylene Glycol, EDTA, Bronopol, Phthalates, Imidazolidinyl Urea, Quaternium, Artificial Colors, PEG, DEA, TEA, MEA, Polysorbates, Talc, Silica, and other harmful chemicals are regularly used in personal care products including antiperspirants and deodorants. Some are potential irritants and others are potential or known carcinogens.

Be wary of labels as they are not regulated strongly. A product can be labeled "natural" and still have highly processed versions of the natural ingredient meaning that they are really poor imitations and potentially harmful chemicals. Even the "organic" label can be abused since only one ingredient can qualify for the label!

Perspiring is actually our body's natural way to cool off. Perspiring allows our body to release toxins. A deodorant works to fight bad odor by stopping the bacteria that causes the odor. Deodorants are generally a better option to antiperspirants. They work to stop the stinking without clogging our pores to stop the sweat; but we still need to read labels and trust the company we choose. We can take control. Our choice in deodorant sends a message to the manufacturer about what we value most in our lives and our future. Thankfully, there are good options available to us.

Our best bet:

The safest based upon safest ingredients and those that are phthalate-free, and the deodorants that we suggest since they really do work, and therefore the only deodorants that we will carry are:

Weleda (particularly for women!): Citrus, Sage, Wild Rose

Tropical Traditions Deodorant (for men too!)

Aubrey Organics: Calendula Blossom, E Plus High C

Terressentials: Fragrance-Free, Zen Spice, Zesty Citrus

Burt's Bees Herbal Deodorant

Crystal Body Deodorant

Active Enzyme Deodorant, Kiss My Face

Alvera Aloe Roll On Deodorant

Alba Aloe Vera Deodorant, Tea Tree Enzyme Stick

Avalon Deodorants

Home's Herbal Magic Deodorant

Earth Science Deodorant

Nature's Gate Tea Tree & Blue Cypress Deodorant

Always read ingredients of deodorants and other skin care products, as well as foods, as packaging facilities, allergy warnings, and ingredients may change without notice. Overall one brand might be better than another brand but that does not necessarily mean that every product in that brand is considered safest. Always read ingredients for each product using this guide of brands and products which were safest when this was written."

I hope this helps!
