|Invented by||Harry R. Drackett|
|Company||S. C. Johnson & Son|
The original Windex was colored a light, transparent shade of blue, but varieties are marketed today in a variety of colors (ocean fresh blue, sunshine lemon and citrus orange) and fragrances (spring bouquet, ocean mist, lavender and tea tree), and with a variety of additives such as vinegar, lemon, lime, or orange juice.
When Windex was invented in 1933 by Harry R. Drackett, it was almost 100% solvent. It was highly flammable and had to be sold in metal cans. When modern surfactants were introduced after World War II, the product was reformulated.
The Sam Wise patent[clarification needed] #3,463,735 lists example formulae, one of which is 4.0% isopropyl alcohol (a highly volatile solvent) 1% ethylene glycol monobutyl ether (a less volatile solvent), 0.1% sodium lauryl sulfate (a surfactant), 0.01% tetrasodium pyrophosphate (a water softener), 0.05% of 28% ammonia, 1% of a dye solution, and 0.01% perfume. This formula was not only less expensive to manufacture, but allowed the product to be packaged in glass bottles and dispensed with a plastic sprayer.
