Description
Manganese (CAS 7439-96-5, EC 231-105-1, formula Mn) is a transition metal commercially known under names including Cutaval and 25Mn, with HS code 81110090. It carries no assigned E-code and is classified within the Salts & Minerals category.
In water treatment, manganese acts as a catalyst in oxidation reactions that precipitate dissolved iron and other contaminants from drinking water. In personal care formulations, it functions as a skin conditioner and colorant, while in agricultural applications it serves as a micronutrient that activates enzyme systems critical to plant metabolism.
Manganese is available in powder form and must comply with REACH registration requirements for supply within the EU. Procurement should confirm grade specifications against relevant pharmacopoeial or food-grade standards depending on end use, as requirements differ significantly between pharmaceutical, nutritional, and industrial applications.
