Alkali metal hydroxides such as sodium hydroxide are strong bases and are very soluble in water; alkaline–earth metal hydroxides such as calcium hydroxide (slaked lime) are much less soluble in water and are not as strongly basic.
Some hydroxides (e.g., aluminum hydroxide) exhibit amphoterism, having either acidic or basic properties depending on the reaction in which they are involved.
Ammonium hydroxide, NH OH, is a weak base known only in the solution that is formed when the gas ammonia, NH, dissolves in water.

 Study Injects New Interest In How Vaccines Work
Purdue researcher Stanley Hem has found that aluminum hydroxide, a small particle used to carry antigens into the body to boost an immune response, begins to dissolve in the muscle immediately after an injection and is eliminated from the body hundreds of times faster than presumed.
During the 1930s, researchers discovered that using aluminum hydroxide to carry antigens into the body resulted in a greater production of antibodies than could be produced by the antigen alone.
Though scientists have puzzled over the mechanism by which aluminum hydroxide increases the production of antibodies, the tiny amounts of the substance used in vaccines made it impossible to track or analyze it once it was injected into the body, Hem says.

 Nutrition Research Newsletter: Aluminum hydroxide as a cholesterol-lowering agent - Diet and Heart Disease
In vitro studies have shown that aluminum hydroxide, an ingredient in some over-the-counter antacids, has a strong affinity for bile acides, comparable to that of the cholesterol-lowering drug cholestryramine.
They were randomly assigned to receive two months of treatment with a chewable antacid tablet containing simethicone, magnesium hydroxide, and 113 mg/tablet of aluminum hydroxide, at a dose of two tablets four times daily, or with the same number of placebo tablets.
Aluminum hydroxide antacids are less expensive and more palatable than the bile acid resins currently in clinical use, and they have a long history of safe use with few side effects in other therapeutic contexts.

 Aluminum
Not surprisingly, other elements in the same group in the periodic table as aluminum, gallium and indium, also inhibit the voltage-gating of VDAC but the potency of their inhibition depends on the amount of the trihydroxide that is present under the conditions used, mainly as a function of pH.
However inhibition by aluminum does not alter the selectivity of the channels indicating that there is no real neutralization of charge that is facing the ion stream.
Thus either aluminum hydroxide is binding and neutralizing charge on the surface domains or the binding of aluminum hydroxide somehow reduces the steepness of the voltage dependence without neutralizing the charge on the sensor.

 Chemistry and the Aquarium
These aluminum oxide materials have been reported to cause negative reactions in certain corals, and one hypothesis that has been suggested is that aluminum is released that irritates the corals.
From the results in Table 4 it is evident that Phosguard does release aluminum to the water, and that the majority of this is present in particulate form (that is, that it is removed on a 0.45 μm filter (although that does not demonstrate that it was originally released as particulates).
However, the aluminum concentration in the filtered sample is not reduced, indicating that the “dissolved” fraction of the aluminum is not altered by rinsing the Phosguard first.

 AAD: Sodium Bicarbonate May Be a Better Abrasive Than Aluminum Hydroxide for Microdermabrasion
NEW YORK, NY -- August 4, 2004 -- The efficacy of sodium bicarbonate appears to be similar to that of aluminum hydroxide when used as the abrasive agent in microdermabrasion for photodamaged skin, according to results of a study of 35 women.
Subjects were aged 25 to 67 years and underwent microdermabrasion with sodium bicarbonate to 1 half of the face and aluminum oxide to the other half.
The researchers found that the sodium bicarbonate formulation significantly decreased mean skin surface sebum content by a mean of 80% on the cheek and 87% on the forehead during the study with no significant long-term effect.
