Windex
Windex is an American brand of glass and hard-surface cleaners—originally in glass containers, later in plastic ones.
The name "Windex" is a registered trademark. Drackett sold the Windex brand to Bristol-Meyers in 1965. S. C. Johnson acquired it in 1993 and has been manufacturing it since.
The original Windex was yellow. Today, it is commonly blue. Varieties are marketed in several colors and fragrances, with a number of additives such as vinegar, lemon, lime or orange juice.
Ingredients
On August 26, 1969, Melvin E. Stonebraker and Samuel P. Wise received U.S. patent #3,463,735 for a glass cleaning composition, listing example formulae, one of which is 4.0% isopropyl alcohol, 1% ethylene glycol monobutyl ether, 0.1% sodium lauryl sulfate, calcium 0.01%, tetrasodium pyrophosphate, 0.05% of 28% ammonia, 1% of a dye solution and 0.01% perfume. This formula was not only inexpensive to manufacture but allowed the product to be packaged in glass bottles and dispensed with a plastic sprayer.In 1989, Windex was a 5% ammonia solution. The product was reformulated in 2006. In 2009, S.C. Johnson started publishing ingredients for all of its products, including Windex. The S.C. Johnson website lists Windex's ingredients as water, 2-hexoxyethanol, isopropanolamine, sodium dodecylbenzene sulfonate, lauramine oxide, ammonium hydroxide, fragrance and Liquitint sky blue dye. An alternative variant also for household use cites water, hexoxyethanol, isopropanolamine, ammonium hydroxide, sodium C10-C16 alkylbenzenesulfonate, lauramine oxide, sodium xylene sulfonate, colorants and fragrances.
