In 1989, Windex was a 5% ammonia solution.[2] The product was reformulated in 2006.[3] In 2009, S.C. Johnson started publishing ingredients for all of its products, including Windex.[4] 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.[5] 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.[citation needed]
