Description

Calcium hydroxide, also called slaked lime, Ca(OH)2, is obtained by the action of water on Calcium Oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime.


Calcium hydroxide is used for several purposes: building material, paper and drinking water treatments, in agriculture as soil conditioner, in food it is ruled as E526 under Regulation (EU) No 2008/13336, concerning a Union List of food additives approved for use in food additives, enzymes, flavourings and nutrients.


Calcium hydroxide is considered of essential use in Organic farming for its efficacy against fungus such as Neonectria galligena.


Many crop plants grow better at a pH of around 6 - 6.5. However, over time, soils tend to become more acidic than this. Lime water is used to raise the pH of the soil, it reacts with acids, and therefore raise the pH.


It has been established that for Calcium hydroxide as notified by the applicant, the following manufacturing impurities are considered, on the basis of information currently available, of toxicological or environmental concern:

  • Barium: Not more than 300 mg/kg
  • Fluoride: Not more than 50 mg/kg
  • Arsenic: Not more than 3 mg/kg
  • Lead: Not more than 2 mg/kg

EFSA authorizes the use as a basic substance having a fungicide action against Neonectria galligena (Pome fruit and Stone fruit).
