What Are the Ingredients in Windex?

SC Johnson’s Windex product contains water and several cleaning agents, such as 2-hexoxyethanol, isopropanolamine, sodium dodecylbenzene sulfonate, lauramine oxide and ammonium aydroxide. The glass cleaner also has fragrance from SC Johnson’s fragrance palette and Liquitint Sky Blue dye.

SC Johnson has begun a product initiative to be more transparent with their product ingredient listings, as of 2015. The company is one of the first American home product retailers to offer ingredient listings for their specific internal fragrance categories. Though not all the ingredients are fully listed for the sake of formula security, the company has vowed to list ingredients of note to within .09 percent of the product mixture.

The Windex brand offers 11 different product variations for glass and other surface cleaning. Each contains a high concentration of ammonia, but there is one product called Crystal Rain that has an ammonia-free formula. The Windex line also has cleaners with disinfection ingredients for spot cleaning areas and ridding surfaces of germs.

Because of its popularity, Windex is often the name referred to for any and all glass cleaners in the United States. The product was first invented and introduced by SC Johnson in 1933 and is best known for its bright blue hue and unique scent. The original formula contained a variety of harmful and some flammable ingredients, but it has been modified over the years to be safer and more eco-friendly.
