Also known as slaked lime, it has a wide range of industrial uses due to its chemical properties and versatility.

Energy Sector

Calcium hydroxide, also known as slaked lime, finds various applications in the oil and gas industry. It is commonly used as a drilling fluid additive to adjust the pH and alkalinity of drilling fluids, and to control the viscosity and stability of drilling muds. It can also be used for neutralizing acid gases in gas streams, such as hydrogen sulfide (H2S), in oil and gas production. Additionally, calcium hydroxide is used for desulfurization and removal of impurities from crude oil, gas, and water in refining and processing operations.

Water Treatment

Calcium hydroxide, or slaked lime, is a commonly used water treatment chemical. It is used to adjust pH, aid in coagulation and flocculation, and soften hard water in drinking water and wastewater treatment. Its alkaline properties help control acidity and alkalinity, while its ability to precipitate calcium and magnesium ions aids in solid particle removal. Calcium hydroxide is a versatile and effective water treatment chemical, ensuring clean and safe water supply by optimizing water treatment processes and meeting regulatory standards.


Calcium hydroxide finds diverse applications in the pharmaceutical industry. It serves as an excipient in tablets, capsules, and suspensions, imparting specific physical and chemical characteristics. It is also used in dental products like toothpaste and mouthwashes for its antimicrobial and pH-regulating properties. Additionally, Calcium hydroxide is employed in the production of calcium supplements, antacids, and laxatives. Its alkaline nature makes it ideal for various pharmaceutical formulations, acting as an active ingredient, pH adjuster, or excipient as needed.
