  • Solubility: approx. 220 g/l in water (20 °C); insoluble in alcohol
  • Uses: main component of the AB57 poultice (with EDTA, Desogen, CMC) for removing black crusts, gypsum and dirt from stone and wall paintings; saturated solutions in compresses for solubilising sulphates
  • Store in a closed container in a cool place (slow decomposition)
  • Manufacturer/supplier: Kremer Pigmente GmbH & Co. KG (Germany)

Safety: Harmful if swallowed; releases ammonia – work with good ventilation. Safety data sheet (SDS) available on request.
