  • anhydrous magnesium sulfate is a completely safe, consumer and environmentally friendly neutral salt.
  • anhydrous magnesium sulfate can also be replaced by other anhydrous neutral salts which correspond to its property profile, and that such salts thus develop a new mode of action in solid drain cleaners which has not hitherto been found in the prior art.
