Calcium Hypochlorite for disinfection of water ITEM CAL-HYPO 65%min CAL-HYPO 70%min Available Chlorine % 65min 70min Water % 5.5-10 5.5-10 Granule Size (14-50mesh)% 90min 90min Calcium hypochlorite exists as a white granular powder and has the formula of Ca(OCl)2. It has a strong scent of chlorine but is more stable than chlorine. It exists as both anhydrous and hydrated forms, giving a basic aqueous solution. The basicity of the solution arises from the hydrolysis reaction, where calcium hypochlorite is broken down into hypochlorous acid and calcium hydroxide. The basicity outweighs the acidity property since calcium hydroxide is a strong base and hypochlorous acid is a weak acid. Calcium hypochlorite is a good chlorine derivative and can release chlorine upon reactions. Calcium hypochlorite can react with carbon dioxide to form calcium carbonate, releasing dichloride monoxide. Similarly, calcium hypochlorite can also react with hydrochloric acid to form calcium chloride, water and gaseous chlorineIt is a solid substitute for liquid sodium hypochlorite for water treatment and bleaching. Calcium hypochlorite is a versatile chemical that finds its application in various industries. Some of its major applications are: 1.

CAS: 99-76-3 MF: C8H8O3 MW: 152.15 EINECS: 202-785-7 Methylparaben is a colorless crystalline powder with a faint characteristic odor and a slight burning taste. It is slightly soluble in water but easily dissolves in ethanol, ether, acetone, and other organic solvents. One gram can dissolve in 2.5 ml of ethanol, approximately 4 ml of propylene glycol, or 400 ml of water at 25�°C or about 50 ml of water at 80�°C. It is commonly used as a fungistat in soft drinks, non-leavened bakery products, and other products, with a permissible level of up to 0.1%. To inhibit Gram-positive bacteria, 1000 to 4000 ppm are required, and its effectiveness increases with decreasing pH, similar to benzoates. Methylparaben is the ester of methyl alcohol and p-hydroxybenzoic acid, It is a bacteriostatic agent and preservative that was added to local anesthetic agents without vasoconstrictors before 1984 to prevent bacterial growth. Allergic reactions developed from repeated exposures to parabens led to the removal of this agent from dental anesthetic solutions. Similar products produced by similar production methods, like ethyl p-hydroxybenzoate (paraben B) and propyl p-hydroxybenzoate (Nepalese c), are also disinfectant preservatives. The products are irritating to the skin.
