Chlorinated lime, calcium hypochlorite

Calcium hypochlorite, colloquially and commonly referred to as chlorinated lime, is in fact an inorganic salt of hypochlorous acid (Ca(ClO)2). It is in the form of a strongly hygroscopic white powder. Like related compounds from the hypochlorite group, it is a strong oxidant. During transport and storage, moisture, exposure to high temperatures, contact with combustible substances and other organic compounds must be strictly avoided. In extreme cases, contact with organic substances may lead to self-ignition of the mixture. When wet, it emits chlorine gas, which is dangerous to human and animal health and life. The product may self-degrade during storage, spontaneously emitting chlorine gas to the environment.

Calcium hypochlorite has strong biocidal properties, which on the one hand make it an ideal component of disinfecting solutions, on the other hand, it is very toxic to aquatic organisms. Under no circumstances should it be allowed to be released into the environment.

It is used to prepare disinfecting solutions that fight algae, bacteria and fungi. It is used in substances intended for the disinfection of drinking and process water, equipment, tools, containers and dishes in the food and feed industry and the HoReCa industry, used to protect water or other working fluids in cooling and water processing systems. It fights pests harmful in these technologies, such as microorganisms, algae, mussels and others.

Attention! Calcium hypochlorite is a dangerous substance. Even in solid form, it can be irritating to the skin, eyes and respiratory tract. When using caustic soda or its aqueous solutions, use appropriate personal protective equipment.
