Question 1

Are there other types of aluminums in this product?

Accepted Answer

Taken from Dr Mercola's web site: REFERENCED: http://articles.mercola.com/sites/articles/archive/2010/02/16/aluminum-lurks-in-crystal-deodorants.aspx"Crystal" deodorant stones are a popular natural deodorant alternative, often used by health-conscious shoppers looking to avoid the aluminum and other chemicals common in most antiperspirants and deodorants. However, if you're looking to avoid aluminum, crystal deodorants may not be your best choice. While many claim to be aluminum-free, they are referring to aluminum chlorohydrate, aluminum chloride, aluminum hydroxybromide or aluminum zirconium.These types of aluminum are widely used in antiperspirants and deodorants. The aluminum is taken into sweat ducts in the top layer of your skin where they act as a plug, stopping the flow of sweat to your skin's surface. There is evidence, however, that this aluminum is absorbed into your body where it may cause serious damage. The aluminum in crystal deodorant stones is a different type of compound known as an alum, the most common form being potassium alum, also known as potassium aluminum sulfate.Potassium Alum or Ammonium Alum are natural mineral salts made up of molecules that are too large to be absorbed by your skin. They form a protective layer on your skin that inhibits the growth of odor-causing bacteria. These deodorants are recommended by many cancer treatment centers. But while this may be a better alternative to most antiperspirants and deodorants on the market, it is not completely aluminum-free.

Question 2

when it falls apart, cracks, breaks, splits? just crush it and put into a spray bottle. just a few bits is all it needs.

Accepted Answer

Interesting, will give it a shot

Question 3

Why aren’t Crystal containers sealed

Accepted Answer

They need to air dry in between use because of what they are made of. I have no idea why, but they always last a long time. I have always used them & they are really good.

Question 4

Whats the shelf life of this stick, does it "melt" or evaporate if stored?

Accepted Answer

If it is kept dry, the shelf life is probably centuries as this is an inorganic white crystalline salt - Ammonium Alum - Ammonium aluminium sulfate - (NH4)Al(SO4)2·12H2O -- see wikipedia or other references. At normal temperatures it does not melt or evaporate. BTW, used properly a single stick can last 1-2 years of daily use -- very economical. The biggest hazard is dropping it on a hard surface which can break it.
