What is Windex?

Windex is the brand name of a glass and hard-surface cleaner since 1933. S. C. Johnson acquired Windex in 1993 and has been manufacturing it since. Ammonia along with various other chemicals help to fight kill germs and bacterias leaving while leaving a shiny, streak-free window.


Scientific Name and Chemical Formula

Ammonia’s chemical formula is, NH3. Windex itself does not have a chemical formula. However, it does consist of multiple chemicals mixed together. Windex composes of:

part1
Fig. 2 Ammonia Molecule (“Ammonia.” n.d)
  • Water
  • 2-Hexoxyethanol
  • Isopropanolamine
  • Sodium Dodecylbenzene Sulfonate
  • Lauramine Oxide
  • Ammonium Hydroxide

Ammonium Hydroxide and ammonia are very similar, the only difference is that ammonium hydroxide contains water and ammonia does not. In simple terms, ammonium hydroxide is the liquid form of ammonia which is a gas.


Chemicals in Windex

Water = H2O

2-Hexoxyethanol = C8H18O2

Isopropanolamine = C18H29NaO3S

Sodium Dodecylbenzene Sulfonate = C3H9NO

Lauramine Oxide = C14H31NO

Ammonium Hydroxide = H5NO

Ammonia = NH3 (1 nitrogen + 3 hydrogen)
