The composition has the form of a powder or an aqueous solution and contains, as the active main constituent, a hydroxymethane sulphonic acid salt, preferably the sodium salt of hydroxymethane sulphonic acid. Preferably, the pulverulent composition comprises hydroxymethane sulphonic acid salt only, whereas the aqueous composition which preferably contains about 20-40 % by weight of an active main constituent, may also comprise optional additives, such as 0.001-1 % by weight of a surface tension depressor which preferably is a cetyl pyridinium chloride, and about 1-10 % by weight of iron or zinc salt for binding hydrogen sulphide. The preferred iron and zinc salts are iron sulphate and zinc chloride, respectively.</p> |
