Magnesium chloride

Magnesium chloride (CAS 7786-30-3) is an inorganic salt commercially available under trade names including TMT 2, Ekimac, Dus-Top, Slow-Mag, and Magnogene. It carries no E-number designation and is categorised under HS code 28273100 within the salts and minerals class.

In water treatment, magnesium chloride acts as a pH buffer and antimicrobial agent, controlling microbial growth by disrupting cell membrane integrity. In building and construction, it functions as a dust suppressant and de-icer by absorbing atmospheric moisture and lowering the freezing point of water. It also serves as a catalyst and flame retardant in polymer processing applications.

Magnesium chloride is sourced in food-grade (FCC), pharmaceutical-grade (Ph.Eur.), and industrial grades, supplied as white powder in 25 kg bags or bulk quantities. It is registered under REACH and compliant with applicable EU chemical regulations. Buyers should confirm grade specification against their intended application requirements.
