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.
Because of the explosion hazard related to hydrogen produced by the reaction of aluminium with hydrochloric acid, the most common industrial practice is to prepare a solution of aluminium chlorohydrate (ACH) by reacting aluminium hydroxide with hydrochloric acid. The ACH product is reacted with aluminium ingots at 100 °C using steam in an open ...
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. [1]
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 .
Up to 20% of aluminium from ingested antacid salts can be absorbed from the gastrointestinal tract – despite some unverified concerns about the neurological effects of aluminium, [11] aluminium phosphate and hydroxide salts are thought to be safe as antacids in normal use, even during pregnancy and breastfeeding.

[3] [4] [5] In the first step, lanthanum oxide is heated with ammonium chloride to produce the ammonium salt of the pentachloride: La 2 O 3 + 10 NH 4 Cl → 2 (NH 4) 2 LaCl 5 + 6 H 2 O + 6 NH 3. In the second step, the ammonium chloride salt is converted to the trichlorides by heating in a vacuum at 350-400 °C: (NH 4) 2 LaCl 5 → LaCl 3 + 2 ...
