Deionised water’s uses: pharmaceutical, cosmetic, manufacturing, laboratory & automotive

Purified of almost all mineral ions including chloride, copper, calcium, iron and sodium, deionised water can be important in environments where a high level of water purity is required.

  • Laboratory & medical: Many laboratory settings have technical standards of water quality, for example when preparing chemicals and mixtures or testing substances for certain compounds.
  • Pharmaceutical & cosmetic manufacture: For the production of cosmetics and pharmaceutical products, deionised water holds uses as a raw material, ingredient or solvent when processing, formulating or manufacturing.
  • Manufacturing: When cooling and lubricating machinery, deionised water prevents the buildup of minerals like salt, as well as preventing interference caused by potential impurities.
  • Automotive: Deionised water is used for flushing and topping up engine cooling systems; the low mineral content prevents scale buildup.
  • Critical cleaning: Used in environments where the complete removal of certain undesirable contaminants is required, for example human medical devices, drugs as well as in cleanrooms.

Deionised water has many other, more niche applications including, but not limited to:

  • Freshwater and marine aquariums: Deionised water is free of copper and chlorine, avoiding the buildup of algae on aquarium plants and keeping inhabitants free of disease.
  • Household: Deionised water extends the life of household appliances like steam cleaners and humidifiers by stopping buildup of mineral scale and lime scale, as well as preventing stains or smears when rinsing cars, windows or other surfaces.
  • Lead-acid batteries: Foreign ions can drastically shorten battery life; deionised water can prevent cells being eroded.
  • Humidors: For preventing stored tobacco products from gathering bacteria, mould and contaminants, as well as preventing residue from forming on humidifier material.
  • Fire extinguishers: Useful as a result of its low electronic conductivity.
