CAMEO Chemicals
Aluminum chloride is a chemical compound with the chemical formula AlCl3. When contaminated with iron chloride, it often displays a yellow color compared to the white pure compound. It is used in various chemical applications as a Lewis base, with anhydrous aluminium trichloride being the most commonly used Lewis acid. It may also be found in over-the-counter as an antiperspirant or prescription products as an antihemorrhagic agent. In antiperspirant products, FDA approves the use of aluminum chloride as an active ingredient up to 15%, calculated on the hexahydrate form, in an aqueous solution nonaerosol dosage form
