Description
Manganese(II) Sulfate (MnSO4), also known as manganous sulfate, is an inorganic manganese salt registered under CAS 7785-87-7 and EC 232-089-9. It carries no E-code designation and is commercially available under the common abbreviations MnSO4 and manganous sulfate.
In agriculture and animal feed, MnSO4 supplies bioavailable manganese to correct soil and feed deficiencies, directly supporting enzyme activation and bone formation in livestock. In water treatment, it functions as an oxidation catalyst, promoting the precipitation of iron and manganese from potable water. Personal care formulators incorporate it as a humectant and skin conditioner at controlled concentrations.
MnSO4 is sourced in technical, feed-grade, and food-grade forms, with food and pharmaceutical applications requiring compliance with FCC or Ph.Eur. monographs respectively. The substance is subject to REACH registration obligations within the EU. Typical packaging includes 25 kg bags and bulk quantities depending on grade and application requirements.
