Tipp-Ex correction paper was invented by Wolfgang Dabisch from Eltville, West Germany, who filed a patent in 1958 [2] on Colored film for the correction of typing errors (German: Tippfehler). He subsequently founded a company of the same name. Shortly after that a Tipp-Ex Sales & Distribution company (Tipp-Ex Vertrieb GmbH & Co. KG) was founded in Frankfurt by Otto Carls. This company still exists under the name of Tipp-Ex GmbH & Co. KG close to Frankfurt.The organic solvent 1,1,1-trichloroethane was originally used as a thinner in the product. This solvent is readily absorbed by the lungs via inhalation. It passes readily through the blood–brain barrier and may be lethal following acute exposure. [6] 1,1,1-trichloroethane is also an ' ozone depleter', being one of the substances responsible for causing damage to the Earth's ozone layer. [7] For both reasons, it has not been added to Tipp-Ex since 2000, and it has been replaced by aliphatic hydrocarbons.

KG) that produced the products in the Tipp-Ex line. While Tipp-Ex is a trademark name for correction products, in some countries it has become a genericised trademark: [1] to tippex or to tippex out means to erase, either generally or with correction fluid. Earlier, in 1951, Bette Nesmith Graham invented the first correction fluid in her kitchen and began marketing the product in 1956 as Mistake Out. [4] Tipp-Ex GmbH only started to produce white correction fluid in 1965 under the brand Tipp-Ex, but also as C-fluid.
