Aluminum chloride hexahydrate, sold under the brand name Hydrosal Gel among others, is a first-line treatment for excessive sweating. [ 1 ] Clinical studies support the efficacy and low incidence of irritation of the 15% aluminum chloride and 2% salicylic acid gel base formula.
Anhydrous aluminium chloride is hygroscopic, having a very pronounced affinity for water. It fumes in moist air and hisses when mixed with liquid water as the Cl − ligands are displaced with H 2 O molecules to form the hexahydrate [Al(H 2 O) 6]Cl 3. The anhydrous phase cannot be regained on heating the hexahydrate.
The variation most commonly used in deodorants and antiperspirants is Al 2 Cl(OH) 5 (dialuminium chloride pentahydroxide). Aluminium chlorohydrate is also used as a coagulant in water and wastewater treatment processes to remove dissolved organic matter and colloidal particles present in suspension.
Side effects if contact occurs may include skin irritation and chemical burns to the eye. [2] They may also cause corrosion and therefore may require being rinsed off. [ 3 ] Specific compounds in this family include sodium hypochlorite , monochloramine , halazone , chlorine dioxide , and sodium dichloroisocyanurate .
Almay Sensitive Skin Antiperspirant & Deodorant provides all-day protection from sweat and odor, while its fragrance- and alcohol-free formula is gentle enough for sensitive skin. As a result, the ...
It is selected for its ability to obstruct pores in the skin and prevent sweat from leaving the body. Its anhydrous form gives it the added ability of absorbing moisture. It is sometimes called AZG, and contains a mixture of monomeric and polymeric Zr 4+ and Al 3+ complexes with hydroxide , chloride and glycine .
Ammonium aluminium sulfate, also known as ammonium alum or just alum (though there are many different substances also called "alum"), is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH 4)Al(SO 4) 2 ·12H 2 O.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
