Calcium chloride hexahydrate

Calcium chloride hexahydrate (CAS 7774-34-7 ), commonly referenced as CaCl2·6H2O, is the fully hydrated crystalline form of calcium chloride used across industrial and food-grade applications. It functions as a desiccant, brine agent, setting accelerator, and preservation aid depending on the sector. Buyers typically source it where controlled water release or ionic calcium activity is required. In food processing, it acts as a firming agent and preservative in canned vegetables, tofu production, and cheese making, where it restores calcium ions lost during pasteurization. Oil and gas operators use it to formulate completion and workover brines, where its high density and solubility help control wellbore pressure without the use of solids. In concrete and construction, it accelerates cement hydration, shortening set times in cold-weather pours. Water treatment facilities apply it for calcium hardness correction in systems. Calcium chloride hexahydrate is supplied as white crystalline flakes or granules. Standard commercial grades include food-grade ( FCC ), pharmaceutical-grade ( USP / BP ), and technical-grade material. Packaging typically ranges from 25 kg bags to bulk quantities depending on application requirements. This material is highly hygroscopic and must be stored in a cool, dry environment.
